Title: Regulatable sliding vane compressor with openings to exhaust medium - with rotor eccentrically arranged in bore of fixed housing and cylindrical housing part having guide edge rotatable about axis
Inventor: FACKLER HANS
IPC: F04C28/14
Filed: 1987-04-06
Abstract: The fixed housing (1) has at least one closable opening on the inlet side (18) and or outlet side (38), additional to the fixed inbuilt unchangeable openings (15, 19) separated from this by the rotatable housing part (12, 13). For volumetric flow regulation, the unchangeable opening (15) works together with at least one closable opening (16, 17) in the inlet side (18) or for regulating the inner pressure relationship, the unchangeable opening (19) works together ith a closable opening on the outlet side. For the independent regulation of the vol. flow and the inner pressure relationship the unchangeable opening (15, 19) works together with the closable opening on the inlet side (18) and outlet side (38). The arrangement of the rotary housing part (12, 13) in the housing (1) as well as the circumferential and swivel range of the part (12, 13) or the arc length of the closable opening is so tuned, that the control edge (24, 27) of the fixed unchangeable opening (15, 19) is not influenced. USE/ADVANTAGE - In sliding vanve rotary compressor gives loss free regulation of volumetric flow and/or inner pressure relationship.

IPC: H04Q11/04
Filed: 1987-06-04
Abstract: This digital communication system comprises a central data processor and several decentralised input/output processors controlling peripheral devices, the functional interaction of the central data processor with the decentralised input/output processors and with the peripheral devices being effected by means of an organisation system control. The organisation system control (OSS) contains hierarchically ordered sequence control units (AE1, AE2 to AEn) with a priority decreasing in order. The sequence control unit having the lowest-valued priority (AEn) initiates, in the non-active state, the reset hold state command (IR) within the sequence control unit having the highest-valued priority (AE1). Such methods are used for controlling digital communication systems having several processing planes. <IMAGE>

Patent DE-3800733-A1 (DE)
Title: Automatic adjusting device for a disc brake
Inventor: HENDRICH UWE
IPC: F16D65/56
Filed: 1988-01-13
Abstract: The invention relates to an automatic adjusting device for a hydraulically and mechanically operated disc brake in which the intention is to prevent adjustment under high braking forces. The invention achieves this by means of an inner piston which projects through the end wall of the brake piston and is actuated by the lining carrier as soon as a sufficient force is exerted on the brake linings. The inner piston, which is displaced into the interior of the brake piston, thus comes into frictional engagement with an adjusting nut, thereby preventing adjustment by the adjusting device. The invention furthermore envisages the support of the brake piston within an inner cylinder which is rigidly connected to the hand-brake piston and is axially displaceable within the housing. <IMAGE>

Title: Spectacles
Inventor: PUPP HELMUT
IPC: G02C7/14
Filed: 1988-07-09
Abstract: The invention relates to spectacles, two transparent optical elements being present in a spectacle frame and which are assigned to the two eyes. According to the invention, commercially available spectacles can be designed in such a manner that, when wearing the spectacles, it is possible in addition to looking forward, also to look backwards without the need for turning the head. This is achieved in that on the inside of the optical elements rear mirrors are arranged which are either placed on the inside or set in the plane of the optical elements. After a short familiarisation time, the spectacles can be worn and used by everybody, can be produced easily and in a cost-advantageous manner and are suitable in particular for all persons for whom it is of great importance to watch at any time what is happening behind them.

Patent DE-3926245-A1 (DE)
Inventor: SCHRUMPF HANS
IPC: B60C23/04
Filed: 1989-08-09
Abstract: A pressure sensor (13) for motor vehicle tyres has a manometric switch for monitoring the tyre pressure, which is actuated by the tyre pressure. The manometric switch comprises a reference pressure chamber (21) which is sealed on the side nearer the tyre by an electrically conductive membrane (22) and carries a contact pin (23). When the air pressure in the tyre is sufficient, the central region of the membrane rests against the contact pin, closing a current circuit. To test for leaks in the reference pressure chamber, the latter is flushed with the compressed air and when the pressure is equalized on both sides of the membrane (22), the membrane (22) is lifted off the contact pin (23). Between the sensor housing (18) and the reference pressure chamber (21) is a semi-permeable sealing ring (31) made of material which is permeable to air and impermeable to moisture, and which therefore prevents moisture from entering the passage (24) through which the contact pin (23) passes into the reference pressure chamber (21).
