Title: AC network internal resistance measuring device - based on principle of voltage drop caused by load impedance
Inventor: PAWLAT JOSEF DIPL ING
IPC: G01R27/16
Filed: 1974-10-15
Abstract: Two load circuits are used, with two different impedances. They have common controllable rectifiers and a circuit responding to voltage drops in the load circuits and controlling the rectifiers, opening them only for one single period or a specified number of periods.

Title: Digestible protein from proteinaceous materials, e.g. raw fish - by partial hydrolysis with organic acids after comminution (NO280676)
Inventor: PENNEY GUY LAURISTON
IPC: A23J3/32
Filed: 1975-12-01
Abstract: Proteinaceous raw materials of animal or vegetable origin are treated for the recovery of >=93% of the digestable material by (a) breaking up the hard fibres or bones into particles of 1 mm dia. and (b) hydrolysing the comminuted material with an aq. soln. of >=1 organic acid to such an extent that the hydrolysate after filtration through a 40 mesh sieve comprises >=70% of the raw material broken down to molecular size or converted to an aggregated molar suspension and that is not>10 wt.% of the raw protein is present in the hydrolysate as free amino acids. Previous processes of this type resulted in hydrolysis to individual amino acids and also led to large amts. of ash in the prd. Use of enzymes as an alternative method of hydrolysis also led to individual amino acids alone or in admixt. with chain-crosslinked amino acids. The invention enables digestable protein to be obtd. directly.
