Title: Butter from cream finely dispersed into refrigerated neutral gas - provides cheaper, longer storing without loss of original quality
Inventor: KRASCHENININ PAWEL FIRSOWITSCH
IPC: A23C15/06
Filed: 1975-01-03
Abstract: During the prodn. of butter from cream, by pasteurising, chilling, holding at the chilled temp., and heating to the point at which butter forms, the cream is cooled first of all to 30-16 degrees C, and then refrigerated to between +6 degrees and 0 degrees C by atomising it into an atmosphere of a neutral gas such as carbondioxide, or nitrogen. It is then maintained at that temp. for 30 mins. The butter thus produced contg. milk fat, humidity, defatted dried milk residues, has also a gas phase, 50-60% of the volume of which is made up on the neutral gas. This reduces the holding time after refrigeration, saving large areas of space and cheapening the prod.

Title: Car seat belt tension limiter - has notched portion which travels between edge pegs when stressed heavily
Inventor: BLUEGGEL ERWIN
IPC: B60R22/28
Filed: 1975-11-26
Abstract: A car seat belt has a coiled-up metal strip which forms part of the belt and which uncoils, when the belt is heavily stressed, to force its way past a pair of pegs.
