Title: Foamed polyolefin and a foamable polyolefin composition therefor
IPC: C08J9/08
Filed: 1980-10-09
Abstract: A foamed (preferably crystalline aliphatic) polyolefin is made from a foamable polyolefin composition containing sodium carbonate as a foaming agent together with an acidifier such as citric acid. Use of the process in making polypropylene strapping tape enables a sodium carbonate/acidifier foaming agent system to be used to obtain a cell structure regular enough to inhibit fibrillation. This is achieved by using a foamable composition comprising 0.05 to 0.4% by weight of carbonate, extruding the foaming composition into an extrudate no thicker than 6 mm and stretching the extrudate after chilling to a stretch ratio of at least 4:1. The polypropylene may be homopolymer or copolymer with ethylene and/or butene-1 and the preferred acidifier is anhydrous citric acid.

Title: Video disc preview apparatus
IPC: H04N5/76
Filed: 1980-10-23
Abstract: A video disc player apparatus having a preview feature. A signal pickup stylus (24) assembly is compliantly mounted (45) in a carriage assembly (20) for translating the stylus radially across the record.

Title: Continuously applying a treating solution as a foam to a cloth
IPC: D06B19/00
Filed: 1980-11-21
Abstract: Treating solution e.g. a dye, is continuously applied as a foam layer to a cloth, the thickness of the foam layer being selected so that sufficient solution is applied, but not so much that excess must be removed.
