Title: Brake pressure regulator for vehicle hydraulic braking system - has electromagnetically-operated blocking device for low pressure reservoir coupled to brake fluid return line
Inventor: DINKEL DIETER
IPC: B60T8/48
Filed: 1991-11-19
Abstract: The brake pressure regulator controls valves (12, 14) inserted in a brake line (5) between a master braking cylinder (1) and each of wheel brakes (10, 11), and between the wheel brakes and the pump (16) inserted in the brake fluid return line (15) feeding the brake fluid to a low press reservoir (18). An auxiliary valve (6) allows the brake line to be interrupted between the pump and the master braking cylinder allowing the brake fluid to be received by the reservoir. The reservoir is blocked when the auxiliary valve is open, via an electromagnetically-operated device (24).

Title: High speed electrophotographic printing - uses printing plate with transparent, anion-contg. polymer layer for image formation
Inventor: RAUH WOLFGANG DIPL CHEM
IPC: G03G17/10
Filed: 1991-12-12
Abstract: A novel electrophotographic printing process is claimed, as is also the printing plate used and a method for prodn. of the plate. The characteristic features of the printing process are that (i) the plate used consists of a photo-semiconductor layer (2) covered by a transparent polymer layer (4) contg. elec. field-diffusible anions and being reversibly changeable from an elec. conducting to an elec. insulating state; (ii) after prodn. of the charge image, layer (4) is conducted with an electrolyte soln. (7) which, on application of a fixing field, extracts anions from positions corresponding to charges in underlying layer (2) so as to give an elec. insulated fixed image in layer (4), this image being repeatedly toner transferred to the material to be printed; and (iii) the fixed image is erased by exposure of layer (4) and soln. (7) to a field opposing the fixing field. Prodn. of the printing plate is by applying in order to a carrier (e.g. supported on a drum) a photo-semiconductor or layer (2), a transparent, conductive electrode (3) and a polymer layer (4), this layer (4) being obtd. (pref. in situ) by polymsn. of an electrolyte soln. contg. a conductive salt as well as a monomer, esp. by oxidative polymsn. of a (hetero) aromatic monomer. ADVANTAGE - Higher printing speeds are attained than in prior-art electrophotographic processes with initial image formation effected directly from digitised data using a computer-controlled laser source (pref. an LCS or LED system) and with the image transfer effected in a high-speed rotary printing process. Fresh images can be directly introduced.

IPC: A47J27/09
Filed: 1993-05-07
Abstract: A steam pressure cooking vessel having a catch, in particular a bayonet catch, between a vessel body and a lid, which catch is to be opened by relative rotation, is described. The steam pressure cooking vessel has a lid-securing device to prevent relative rotation between lid and vessel body when the cooking vessel is under a predetermined internal pressure.
