Patent DE-3015409-A1 (DE)
Inventor: LINDER ERNST DIPL ING
IPC: F02B1/04
Filed: 1980-04-22
Abstract: A rotary vacuum pump is proposed, having a rotor with vanes which rotates eccentrically within a housing bore. Each vane is coupled with a body which is ineffective at relatively low pump rpm; however, at higher rpm, the body engages the vane in such a manner that it removes the vane from its track within the housing bore. In this manner, an rpm-dependent shutoff device is created for the pump. In cooperation with the furnishing of underpressure as an auxiliary pressure in motor vehicles, the pump is used to supplement the underpressure which prevails when the internal combustion engine is at low, idling rpm; this prevailing underpressure is at a very low pressure level, and so when it is thus supplemented there is sufficient auxiliary vacuum force available over the entire rpm range.

Title: Throttle, stop and/or two way valve - has plug guided axially with seal in housing and spindle acting against seat
Inventor: EGLINSKI JUERGEN
IPC: F16K31/363
Filed: 1980-06-04
Abstract: The valve has a setting spindle thrusting a plug against a coaxial seat. Holes are connected to the seat and to the space round it, and an unloading hole passes through the plug. The plug (4) has a seal (8) acting against the housing (1), in which it is guided in the axial direction, and also a passage (11) leading to its face at the spindle end. At the other end, this passage connects to the lower-pressure chamber of the two round the valve seat (6,13). The free end of the spindle (15) acts against a seat (12) formed in the passage end so as to shut it off, and limits the amount for which the plug can lift off its seat. The unloading hole (9), emanating from the plug face at the spindle end, contains a throttle (10), and leads to the highest pressure chamber (13,16).

Title: Contact assembly for electronic component measurement and testing - has piston in internal case and sliding contact ring
Inventor: KRUEGER GUSTAV DIPL PHYS DR
IPC: H01R11/18
Filed: 1980-06-14
Abstract: The contact element has a contact piston (10) inside a case (7) which is pressed against the end of the case by a coil spring. It enables a four pole measurement to be achieved in a very small space without the measurement being adversely affected by mechanical clamping or insufficient isolation. An external case (1) concentric to the piston case (7) retains an axially movable contact ring (5) acted upon by a bias spring. The contact ring (5) and external case (1) are electrically isolated from the contact piston (10) and inner case (7). The insulation material may consist of plastic or a non-conducting oxide layer. The contact piston and ring surfaces (13,14) protruding from the casings have cutting edges.

Title: Control of sweet flow to feeder - having rotating table which feeds individual sweets being on weigh scale and controlling vibratory feed from this signal
Inventor: HAERTWIG SIEGFRIED DIPL ING
IPC: B65B37/18
Filed: 1980-09-20
Abstract: Process is to control a sweet feeder stream to a distributor plate which sorts out the stream into individual sweets. The wt. of the rotating distributor is continuously monitored and the signal from this is used to regulate a vibratory feeder which feeds onto the distributor. The weighing mechanism can be an electrical load cell device with elastically deformable members. The weigher can be on a balanced beam with a conventional sensor to monitor the wt. The mechanism is for use in sweets mfr. As the feed stream is accurately controlled it is not necessary to alter or switch off the feeder frequently.

Title: Reciprocating internal combustion engine - has inlet and exhaust valve openings positioned to give complete scavenging
Inventor: TRINKNER ADOLF
IPC: F02F1/42
Filed: 1980-11-05
Abstract: The engine has a cylinder (1) with a cylinder head (3) forming a combustion chamber (5) with a dome shaped top. Inlet (12) and exhaust (13) passages are controlled by mushroom headed poppet type valves (7,8). The inlet passage has a constant cross section (22) upstream of the valve with a short section (23) of increasing cross section immediately on the inlet side of the valve. The opening of the inlet passage into the cylinder immediately above the valve seat (16) lies in the plane of the face of the head of the exhaust valve (8).

Title: Endoscope with an image-transmitting flexible element
IPC: A61B1/00
Filed: 1981-03-24
Abstract: Endoscope with an image-transmitting flexible element which is exchangeably located in the outer tube of the endoscope. As a rule, these are fibreglass elements which can be easily released from, pulled out of and re-inserted in the outer tube. In order to ensure a reliable connection between the distal end of the endoscope shaft and the distal end of the image-transmitting element, it is proposed, according to the invention, that the distal ends have a fastening device which rules out slipping of the image-transmitting element relative to the distal end. <IMAGE>

Abstract: The invention relates to an object for levelling the intensity of radioactive radiation, radioactive material being packed in a protective mass in such a way that in the case of manual manipulation direct bodily contact with the radioactive material is avoided and distribution of radioactive particles in the air, in liquids or on human, animal or plant bodies is prevented.
Patent DE-3202252-A1 (DE)
Title: Deformable seal for the gap between an opening in a building and a vehicle drawn up to said opening
Inventor: ALTEN KURT
IPC: B65G69/00
Filed: 1982-01-25
Abstract: In the seals, there is situated between a downwardly open U-shaped frame for mounting a deformable apron on the one hand and the building on the other hand a cover which is distorted by, due to its being articulated on guide bars, being subjected to a slight lifting movement when the apron is struck by a vehicle. In order to eliminate disadvantageous deformations of the cover, the edge of the cover facing the building is guided height-adjustably. To prevent the apron from being deflected when it has been very slightly deformed, and its sealing action is thus diminished, the edges of the cover can be displaced upwards only against the action of a tension spring which, advantageously, is intended to act on the guide bars and/or the U-shaped frame.

Title: Pivoting interruptor switch for high voltage
Inventor: ZUERCHER ERNST
IPC: H01H31/02
Filed: 1982-05-03
Abstract: The switching blade (3) which pivots into the stationary contact (5) would theoretically follow the line of the arrow (6). However, because the switching blade (3) is in oscillation, it follows the line of the arrow (10) to the limiting stop (52), temporarily deflecting the stop (7) against the spring (71) in the direction of the arrow (72). From the limiting stop (52), the switching blade (3) would bounce out of the stationary contact (5) again along the line of the arrow (11) whereupon it is impeded by the lock (7) and then moves into the contact piece (9) along the arrow (12). <IMAGE>

Title: Video recorder recording a vision carrier
Inventor: KLUTH HANS-JUERGEN ING GRAD
IPC: H04N9/83
Filed: 1982-07-22
Abstract: It is known that a vision carrier frequency-modulated with the video signal is recorded in a video recorder. According to the invention, the limits of the frequency deviation are allocated to the signal values of black and white. The synchronisation pulses (S) are recorded with an auxiliary signal outside the frequency spectrum of the vision carrier. Full utilisation of the range of frequency deviation for the composite video/blanking signal results in a higher signal/noise ratio or greater video band widths. <IMAGE>
