In order to determine whether in the case of a plastic bottle there are present in the region of the base of a bottle fatigue cracks which exclude the further use of the bottle, the measuring beam of a laser distance measuring device is applied to the base of the bottle in the region of the crack. The quantity and depth of the cracks can be detected from the output signal of the said device to the...

Polyurethane foams blown with a mixture of water, HCFC-22 or HCFC-141b, and a perfluorinated hydrocarbon having from 3 to 8 carbon atoms yields polyurethane and polyisocyanurate foams having exceptional physical properties, i.e., small and uniform cells, low initial K-factor, low aged K-factor, and high tensile strength. The low initial and aged K-factors are most unexpected when it is considered ...

11 To determine whether stress cracks are present in the bottom area of a plastic bottle which make it unfit for further use, the bottle bottom is scanned in the potential crack region by the measuring beam of a laser distance-measuring instrument. From its output signal, the prevalence and depth of the cracks can be identified sufficiently to enable a decision to be made on the removal of the bot...
