Title: Process for extracting and processing glycoproteins, mucopolysaccharides and accompanying substances
IPC: C07K14/00
Filed: 1975-02-25
Abstract: The extraction and processing of glycoproteins and/or mucopolysaccharides and accompanying substances, from natural substances, such as tissues of animal, cryptogamic, bacterial or other plant organisms, or materials produced by such organisms is disclosed. The substance is treated with water of buffers with a pH value of 7.5 to 9.5, in one or more stages, at between atmospheric temperature and 110 DEG C.

Title: Vehicle transmission control system
IPC: B60W10/10
Filed: 1980-08-14
Abstract: A control system for an automatic vehicle transmission includes a clutch mechanism interconnecting the driving connection between the vehicle engine and the vehicle driving wheels.
