Very good point about reading the insurance policies in place and seeing what they will or will not cover. Personally, I don't specify overhead glass in which the inner leaf is monolithic toughened. Although, it is termed a 'safety glass', such that the failed glass is supposed to form into relatively harmless particles, it can in fact fall out in large clusters of interlinked particles that disintegrate only on impacting something or someone below. So, I normally go with a laminated inner leaf with either toughened or heat strengthened or a combination of these glass leaves each side of the interlayer. The idea is that if one of the leaves breaks then the interlayer and opposite intact glass leaf should hold it in place until the unit is renewed. Safety films have been applied retrospectively to the inner glass surface, sometimes as a safety measure. But it is necessary to trap the film edges in the peripheral glazing rebates (assuming it's a framed installation) or by mechanically secured angles, otherwise you can have a sheet of failed toughened glass falling to the ground and wrapping itself around the nearest object or person. The distance from which the glass falls and its momentum also has some bearing on the risk from failed falling glass. |

I sometimes defer to the original spelling when nickel sulphide/sulfide failures were prominent in the early 90's. You can't assert a failure cause without preferably seeing what remains of the cracked/shattered glass insitu. I agree that poor glazing practice is an issue too, along with damage from transportation and handling. Which is why edge/surface damaged glass should not be installed. In a case where the shattered toughened glass had fallen out, someone was tasked with collecting and sifting all of the particles and they did in fact find the nickel sulphide particle embedded in a glass dice from the seat of the break. Another case to do with a large shopping centre with a complicated glass roof had a team of representatives peering over the glass installation and discussing the migratory patterns of birds in the area as they believed that birds were picking-up roof ballast in their beaks then dropping it on the glass. Although this has been known to happen, the true cause of these breakages was a disgruntled employee who used his free time to go on to the roof and lob stones at the glass. Another building alongside the Chiswick flyover had multiple failures and while the early investigations considered traditional failure causes, the real cause was someone taking pot shots at the building when passing in a vehicle. Which fenestration surveyors/engineers have you worked with? I may have dealt with them too. [Post edited 22 Feb 10:48]

Haha I needn't have gone fully in to 'work mode' describing nickel sulphide inclusions. When you get your new screen, it should have an identification stamp in one of the glass corners. It should be marked with one of BS EN 12150 or BS EN 14179 if processed in Europe. Take a photo for your records. Also, when you receive the new glass check there are no damaged edges (it should be ground flat and sometimes the edges are polished also) or deep surface scratches. Any damage inherently weakens the glass and acts like a stress raiser from which cracks/breakage can propagate in future. So, damaged glass should be returned. |

Spontaneous breakage of toughened glass can be attributed to nickel sulphide inclusion. This is a foreign body that can become trapped in the glass during manufacture. The nickel sulphide inclusion undergoes a time and temperature related phase change causing it to grow in volume. The force of that phase change exceeds the strength of the surrounding glass causing it to break. Nickel sulphide is a particular problem with toughened glass because of its integral stresses in opposition to the inclusion. So, toughened glass should be made to BS EN 12150. Published authority states that such glass has a risk of spontaneous breakage from nickel sulphide in the range of 1 in 4 to 6 tonnes of toughened glass supplied. Toughened glass begins as ordinary float glass. It is then floated on a bed of rollers and warmed while moving back and forth. The glass is then cooled rapidly by jets of cold air. This imparts compressive stress in the glass surface and balancing tensile stress in the body of the glass. The toughening process imparts the glass with greater resistance to heat and mechanical load compared to ordinary float/annealed glass. And toughened glass is also considered to break safely by failing into small dices or particles that disintegrate and fall to the ground. This is different from float glass that can break into dangerous shards that can cause injury. So toughened glass is commonly described as a 'safety glass' and it is why it is used in shower screens and in other vulnerable applications. This has been a recognised problem for some years and there have been lots of such breakages in buildings and high profile legal cases. The industry responded by introducing a quality control technique called 'heat soaking'. This takes toughened glass and puts it in an oven and heats the glass for a set period. The idea of heat soaking is to promote the phase change of any inclusions within the glass so that the glass pops while in the glass works. Heat soaking supposedly changes the breakage risk to 1 in 400 tonnes of glass supplied and such glass must be stamped to say it is made to BS EN 14179. The loud bang that you hear when toughened glass breaks is from release of its internal stresses. Toughened glass can also break from impact if you sufficiently gauge the surface to the point of penetrating the outer compressive zone but such failure would normally be instantaneous and you would be aware of the thing causing damage. So, absent any other explanation you might want to tell you insurers the above explanation. Sometimes, if you're lucky, the glass hangs in position until the effects of gravity or a wind gust say cause it to fall out. In those situations, you can sometimes trace the origin of the break to a butterfly pattern or back to back double D pattern and in the straight line of the butterfly you can sometimes see a very fine spec that is the nickel sulphide inclusion. I've previously retrieved lots of these and had them formally identified in a laboratory under a powerful microscope. But, identification is usually impossible when all of the particles fall out and disperse as in your case. I hope that this helps. [Post edited 21 Feb 12:39]

Jerry. Tall and slim, white hair and glasses. I can't remember the year he died. He was friendly with an Irish couple in there that (from memory) ran a B and B I think and I always found them very nice. The B and B owner man had distinctive white hair too. I'd often join Jerry for a Sunday pint along with 2 of my in laws. [Post edited 29 Jun 2023 11:09]

Same person then. I'm not sure if John knew what to make of us turning up at The Century. He seemed friendly. But we were maybe 17 or 18 and loud and well on our way from starters in Stallone's. I remember the pub name now you say it but, it also went by another name for a while and that's the one I'm struggling with - I liked it at the time and it was preferable to The Greyhound opposite. I lived near the stadium for about 5 years before leaving home, so was fairly close to Llanover Road. I later moved to Kenton, after which Wembley pub visits were typically limited to having a beer with my fantastic father in law in The Green Man. I've met a few Irish mothers and equally heard lots of things that are hilarious, but that can't be repeated on public forums! [Post edited 29 Jun 2023 11:07]

There was a John Higgins in my brother in laws class. He'd be about 64 now. After leaving Manning we used to do Friday night pub crawls from a little pub at Wembley Triangle (that sold Newquay Steam beer) to The Century and then on to the Dog and Duck at North Wembley. John was often in The Century and I remember being told he was investing in houses in his early 20's. This has reminded me that there was also an unusual act in The Century involving a lady and very large snake. I was never that comfortable around the snake. John knew my mates older brother.

Yes, I have fond memories of all the teachers save for Mrs Cobb who slapped my legs more times than I care to remember. Mr Rainbow was fantastic. We also had a great sports teacher called Mr Williams. There's a Malorees Facebook page and I joined some former class mates for an exchange a year or so ago, which was nice. |

Also attended Malorees Infants and Juniors. Mr. Singer was head. Left around 76 or 77 I think. Then Cardinal Manning in Ladbroke Grove, followed by several years of Old Boys football for them. |

Ok then. So, if you're in France and in reach of a Decathlon store here's a link to a wheel mounted smart trainer. It's pretty cheap for what you get. Also, if you're interested you can find online a guy called DC Rainmaker who does great tech reviews on bike and other sports kit/watches etc. With the option below you will probably need to get an Ant+ dongle (unless there's one in the box) to connect the trainer and app. It's also a good idea getting a cadence sensor that attaches to your pedal crank. This is because a lot of sessions will factor your revs per minute and encourage you to spin efficiently. I also like wearing a heart rate chest strap because the apps can keep track of that too and it adds another training metric and helps gauge if you are roughly fit or maybe overtrained or going down with a bug say. The direct drive (wheel off) smart trainers are the next step up from this and they probably cost in the range of £500-£1k. The top option is a purpose designed training bike like a Wattbike or Tacx Neo bike, but they cost an arm and a leg and there's no point considering that if there's a chance indoor biking is not your thing. As far as training apps are concerned, I've tried Zwift and it's the most widely advertised on TV but, I love using Wahoo X as you can choose a training calendar and make it sports specific or multisport. I choose the multisport option and mix in a bit of structured running and swimming plus is has bolt-ons for 15 min yoga sessions and separate bodyweight strength sessions which help me now I'm older. If you're new to this I definitely urge you to consider the smart trainer option because it made indoor biking so much engaging than before.
Also, these trainers are heavy. They need to be to stop you from toppling over. So, I'd expect a lot of Ebay sales to be collection only unless you find a retailer who's prepared to deliver.

If it's a rudimentary trainer you're after and are prepared to pick up in Hove, I've got one you can have for free. It's about 20 years old. An old Tacx model. It has an integral headset that clips on handlebars that you can tinker with to simulate an up or downslope and this changes the resistance through the back wheel. These things have a clamping pressure each side of the back wheel axle so it's best to have one that is all metal (including the nuts) to cope with the clamping pressure. I'm sure it's in the loft. You preferably need a front wheel riser too so that the training bike is level. And, I like the idea of a separate training wheel with training tyre as the tyre especially runs a bit quieter. And though you are welcome to this I'd say it is also worthwhile seeing how cheaply you can alternatively find a 'smart trainer'. These can look like what you want but they can connect to the net and allow using apps like Wahoo X and Zwift etc where you can take part in structured training sessions or bike rides or races for that matter. They can be set in Erg mode that controls the resistance through the back wheel which varies according to the amount of power the session might require you to apply or to simulate up or downhill. The apps really transformed bike training for me and if I'm well I'd normally do a couple of midweek indoor bike sessions and a weekend outdoor ride. I use another setup these days. |

Made me laugh Brian. You can have fun playing up to the stupidity. I was in my brother in laws pub in a place called O’Meath and a coach pulled up filled with tourists. The driver was in a panic as the tour guide didn’t show up. So he negotiated terms for a local to stand in. The coach set off and stopped 20m down road at which point the tourists got off and were photographing what they were told was the ‘oldest telegraph pole in Ireland.’
Worst film - we left part way through a 1987 film called the Glass Menagerie and headed for the pub. |

On a family trip to Connemara detoured to a place called Roundstone (County Galway) and found this stunning white sand beach called Dogs Bay. A friend had separately camped there and we both agreed the place had a good vibe. Also enjoyed Narin and a Portnoo beach in Donegal. |

Loved the article NW5 and everyone's reflections on bringing youngsters to R's games, home and away.
We did the mascot thing too and because of the occasion my mum and wife decided to come and it was possibly the first time both had been to see the R's. It was against Scunthorpe I think. Our group was bigger than usual and we got seats together near the away supporters. I was settling in to watch the game and my wife has taken offence at something Scunthorpe were singing and got on her feet and started shouting in their direction. She was really getting into her stride when I gave her a nudge and told her they are currently working out a song to sing just to her and it won't be nice so she had better sit down. So she did. I thought that was the end of it. But once the game got underway she then wasn't best pleased about the refereeing decisions and turned to my mum and asked her if they should both start calling the ref a 'banker' and my mum agreed that they should! Haven't taken either of them to a game since. |

Wholly off topic but, that's going back a while and to a time when you could do day and night courses while working the rest of the time and the RICS set exams as a route to membership. Found him a bit amusing, but can't remember why. There was also a new lecturer called Joe Kehoe who we respected because he worked hard for us. Joe later moved to Cork. |

Likewise. Be good to see the openers play like test cricketers. That said, was impressed by India's bowling attack in last test. Thought they were aggressive and varied bowling over/around the wicket as well as angling many of the deliveries. Is it Bumrah who manages 85mph off very short run ups?

For whatever reason I've only just registered Kohli and found him irritating. He did remind me of the Aussie team in the 2000s. Kohli is articulate when interviewed though. |
