Title: Rubber hot-water bottle closure
Inventor: LANGE GEORG OSWALD
IPC: A61F7/02
Filed: 2000-01-05
Granted: 2005-06-28
Abstract: Existing rubber hot-water bottles have a screw-type closure which is arrange d directly on the hot-water bottle, and which forms a rather hard seal which causes discomfort to the user when lying on the bottle. Moreover, a screw-ty pe closure is tedious to operate and must be screwed in using a certain amount of force which also corresponds to forces required for loosening. In order to avoid these disadvantages, the invention provides that the bottle neck (21) is configured in such a way that the closure is located distinctly at a distanc e from the body (20) of the bottle when the fill opening (22) is closed. According to another embodiment, a clamping device (23, 40, 60) is provided on the bottle neck (21) of the rubber hot-water bottle with which the bottle ne ck (21) can be closed. Clamping devices are easy to operate and require only a small amount of force for closing. In addition, they are easy to open and comprise a very flat design so that they do not cause discomfort to the user .

Abstract: An improved plug device for sealing an internal tubular passageway in a predetermined location against pressure and flow applied from one side. The plug is selectively inserted and retrieved from the tubular passageway using an installation tool. The plug has an elastomeric seal and multiple latch dogs that reciprocate in an axial direction to engage or not engage the tubular passageway. An elastomeric seal of the plug is manipulated to cause it to recess during the installation and retrieval of the plug device to minimize scuffing the seal. Multiple latch dogs housed in the plug are radially moved outward to engage a prepared internal groove in the tubular passageway, then the elastomeric seal is relaxed to bias against the interior of the bore of the tubular passageway. The plug is easily installed and removed by robots or remote manipulators.

Abstract: Selon l'invention, des compositions polyuréthannes sont fabriquées au moyen d'un procédé à deux étapes. Dans une première étape, un composant diol ayant une masse molaire inférieure à 2000 est transformé avec un diisocyanate monomère ayant une masse molaire inférieure à 500, et le diisocyanate monomère non transformé est retiré du produit de la transformation. Dans une deuxième étape, le diisocyanate macromoléculaire ainsi fabriqué est transformé avec un polyol de manière à produire un prépolymère réactif ayant des groupes terminaux isocyanates. L'addition de polyisocyanates ayant un pouvoir migrateur et présentant une pression vapeur nettement inférieure à celle du diphénylméthane-diisocyanate permet d'améliorer l'adhérence des compositions polyuréthannes selon l'invention. De telles compositions polyuréthannes peuvent être utilisées en tant que liants pour des colles ou agents d'étanchéification réactifs à une ou deux composantes, pouvant éventuellement contenir des solvants. Lesdites compositions peuvent par ailleurs être utilisées dans la fabrication de colles fusibles réactives lorsque l'on emploie des polyols adaptés. Par rapport aux compositions polyuréthannes connues, les compositions selon l'invention présentent l'avantage de faire intervenir une quantité fortement réduite de diisocyanates monomères ayant une masse molaire inférieure à 500.

Abstract: The present invention provides a method of detecting the exceeding of a predetermined limiting value in a radioactivity measurement. A total duration of measurement for a contamination measuring device is calculated. Several single measurements are taken with the measuring device. After each single measurement, based on previously measured single measurements, the probability that the mean value of all measurements exceeds the predetermined limiting value is calculated. If the probability is smaller than a predetermined certainty, then a signal is generated which stops any further measuring. As such, within a shorter duration of measurement than the total duration of measurement, a probability with a sufficient reliability has been calculated.
