Title: Biocompatible porous membrane prodn. with definite cut=off - by coating porous membrane with isotropic carbon, useful for plasma sepn. or sensor
Inventor: CHMIEL HORST PROF DR ING
IPC: B01D67/00
Filed: 1980-04-05
Abstract: The prodn. of a biocompatible porous membrane with a definite sepn. sharpness (exclusion limit) involves coating the porous membrane with biocompatible isotropic C (I). The active pt. of the membrane is produced entirely from (I). The membrane can be perforated first and then coated with (I) or coated with (I) and then perforated. Perforation can be effected by ion or nuclear ray bombardment, followed by etching, whilst the (I) coating can be produced by cathode sputtering, ion beam sputtering, ion plating and/or electron beam evapn. It is also possible to apply (I) to a substrate, e.g. a PTFE film, e.g. by cathode sputtering, then bombard it with a beam of particles to perforate it, after which the (I) film is transferred to a supporting membrane. In comparison with certain other membranes, which adsorb and/or change proteins, the new membrane is more compatible, is not harmful to body fluids, esp. blood, when in contact with these and does not suffer impairment to its function by deposition or adsorption. Membranes of this type are useful as plasma sepn. membranes and sensors, e.g. glucose sensors implanted in the bloodstream.

Title: Multiple lock system for coded information - uses change of master key providing new master key with altered programming
Inventor: KREPPEL CHRISTIAN
IPC: G07C9/00
Filed: 1980-08-19
Abstract: The locking system operation is intended to provide high degree of flexibility combined with high security. The number of locks in the system is presettable, and both the locks and their keys store a coded information, changeable only under certain conditions, in order to release a lock when both the lock and key switch. The matching code thus identifies the key. In this manner keys used as master keys can preset a lock for other than normal operation such that during a limited time period a matching key is inserted into a non-matching one, and vice versa. A lock, operated by a matching master key, is so changed that no master key fits this lock. The latter then programs a predetermined key as a new master key. The previously fitting master key may be again reprogrammed for this operation. Thus the use of unauthorised key(s) can be prevented.

Title: Motor vehicle brake pressure ratio valve - has housing with differential piston between inlet and outlet chambers, with valve coupling auxiliary piston surfaces
Inventor: GRUENER HANS
IPC: B60T8/26
Filed: 1980-11-25
Abstract: The valve has a housing (1) with a differential piston (8) so that pressure from the brake operating valve (15) enters a control chamber (16) and passes through an inlet valve in the main piston into an outlet chamber (20), connected to the wheel cylinders (22). Increased pressure pushes the main piston up, closing its inlet valve (10,12). Pressure in the control chamber opens a valve in an auxiliary piston (23) on the main piston, thus increasing the surface area of the piston. Then it is pushed down to reopen the inlet valve. On releasing the brake the piston rises, and a discharge valve (10,13) opens emptying the outlet chamber and releasing the brakes.
