Disintegrating HP-41 pouch Message #1 Posted by Juergen (CH) on 15 Sept 2004, 5:27 a.m. The inside of my 41 pouch (the brown one which can also hold the card reader) is disintegrating. Small black crumb is polluting my calculator. What can I do? Should I wash the pouch? For my other 41, I have a smaller black pouch. The inside is furred and shows no signs of disintegration. Seems to be a much safer place for my calculator... Cheers, Juergen

Re: Disintegrating HP-41 pouch Message #2 Posted by Raymond Del Tondo on 15 Sept 2004, 6:14 a.m., in response to message #1 by Juergen (CH) Hi Juergen, just throw away the disintegrating pouch, or you'll have the black snow forever;-) I also have some of these pouches. From my experience, the HP-41 pouches with the small sharp-edged zipper latch are the ones which are disintegrating. Maybe they used a different material, or the pouches have reached a specific age now, compare to the card reader wheel... Regards, Raymond

Re: Disintegrating HP-41 pouch Message #3 Posted by Jeff O. on 15 Sept 2004, 7:06 a.m., in response to message #1 by Juergen (CH) Based on recommendations from this Forum, I put mine through a cycle in the washing machine, then let it air dry. The crumbly disintegrating stuff was eliminated. Worth a try before you throw it away.

Re: Disintegrating HP-41 pouch Message #4 Posted by Thibaut.be on 15 Sept 2004, 7:08 a.m., in response to message #3 by Jeff O. yes, this is often the case with Spice series pouches... I store my spices out of their pouches but keep the pouches, otherwise there's no use to build up a collection...

While browsing through the Forum Archives I've found the following two threads regarding the same problem: Disintegration of vinyl case Disintigrating 41C soft case

Re: Disintegrating HP-41 pouch Message #6 Posted by Valentin Albillo on 15 Sept 2004, 9:16 a.m., in response to message #1 by Juergen (CH) Same here, a few years ago, with my HP-71B 'pouches'. In my experience, there are two reasonable things you can do, in this order: 1) Wash the offending pouch thoroughly, till all the disintegrating dust is completely eliminated. You'll know it's enough when the pouch, once dry, expels no dust whatsoever under strong agitation and severe tapping with the hand over a blank sheet of paper. Afterwards: 2) Place your calculator *inside* a Teflon plastic envelope, which can be either thermo-sealed if it's just a collector's item intended for long storage, or else left open if you use or take out the machine frequently. Then place the teflon-enveloped machine inside the pouch. This will prevent any further 'contamination' should the pouch keep disintegrating but even better, it will absolutely protect your valuable calculator against any scratches and wear (such as logo wear on the Voyager series and the 71B). I do exactly like this, with excellent results over the passing years. Frankly, putting an HP-15C, say, in and out of its original tight pouch on a frequent basis should be regarded as criminal behavior. Best regards from V. Edited: 15 Sept 2004, 9:17 a.m.

CalcPro had some the last time I looked. If that is not what you need CalcPro also has a belt clip pouch that works real well too.

Re: Disintegrating HP-41 pouch Message #11 Posted by Juergen (CH) on 15 Sept 2004, 1:44 p.m., in response to message #8 by Mike (Stgt) French rubber => safer calculating? Which flavor do you recommend: banana, strawberry, ...? And what about my HP-85? I guess it does not fit into a rubber, even into XXL sized ... Just kidding ;-)

Re: Disintegrating HP-41 pouch Message #12 Posted by Mike (Stgt) on 15 Sept 2004, 2:35 p.m., in response to message #11 by Juergen (CH) I recomend those strawberry flavoured from MIGROS (a big Swiss food and non-food distributor), AFAIK they are manufactured in Sweden. So it will be safe European wrapper for that "disintegrating" pouch (from Asia I suppose). Ciao.....Mike

Rubbers Joke Message #13 Posted by Thibaut.be on 16 Sept 2004, 4:12 a.m., in response to message #12 by Mike (Stgt) Regarding the flavour, sorry, I dunno, I'm not the one that usually taste them. Sorry Dave, I know it's not the place for such jokes, but I can't help telling this one : President of France calls the Belgian Prime Minister, Guy Verhofstad, and tells him : - Guy, we're in big trouble. We're out of rubbers supply. Could you produce some extra more for us ? you know we French lovers are very active, and I don't want to be held for responsible for increase of disease transmission. - Sure, Jacques. What size do you want them ? - Well, according to our recent statistics, they should be 15 inches long and 3 inches wide. 100 million units will do. - No problem. I'll take care of that. The Belgian Prime Minister calls the Minister of Economy and tells him : - You need to procude 100 millions rubbers for France. Size is 15 inches long and 3 inches wide. - Huh ? are you sure Sir ? Isn't there a misunderstanding regarding the size ? - Not at all. Just write down on them "Made in Belgium. Size : XXS".
