Patent DE-2942926-A1 (DE)
Title: Hydraulic tappet for IC engine - has piston sealed to cylinder with air vent above piston
Inventor: REITZ JOHANNES ING GRAD
IPC: F01L1/25
Filed: 1979-10-24
Abstract: The tappet has a cylindrical body with a crown piece which has an internally projecting cylinder. A piston (2) fits tightly in the cylinder. Oil is admitted to the inside of the piston through a radial passage (2). A plate (5) is held above the piston by a spring. The piston is sealed (3) to the cylinder but the plate has a small clearance (6) to it. Air passes through the clearance easily while oil flows through it very slowly. The air is thus vented and is discharged through an annular channel (7) surrounding the plate (5) in the crown. There is a radial outlet (8) from the channel.

Title: Transport and storage vessel for irradiated fuel elements - has firmly pressed inner liner giving good thermal contact
Inventor: HACKSTEIN KARL-GERHARD DIPL CH
IPC: G21F5/008
Filed: 1979-12-22
Abstract: A transportation and/or storage vessel for radioactive wastes, esp. irradiated fuel elements, consists of a heavy outer vessel to provide the structural strength and an internal vessel to provide the necessary corrosion resistance. These two are intimately locked together to provide a good thermal connection between them as follows. The internal vessel is of round or angular (polygonal) shape, and has prismatic beadings at the corners or sides engaging into corresp. beading-shaped recesses or grooves in the outer vessel. The inner vessel is firmly pressed into the outer vessel to form a good contact. In addn., the inner vessel may also have radial beadings engaging into corresponding grooves in the outer vessel. In a variant, thermally conducting and/or radiation shielding material may be incorporated between the inner and outer vessels. A good thermal connection between the two parts of the vessel is assured, ensuring removal of the decay heat of the fuel. The internal lining can be easily replaced when necessary.

Title: Belt adjusting system for vacuum drying vessel - uses pressure changes to operate pneumatic servo system controlling belt adjuster
IPC: F26B17/04
Filed: 1980-09-06
Abstract: The vacuum drying vessel with an endless conveying belt passing around rollers (14) inside, has selected rollers supported by 'U'-shaped frames (20) for adjustment. Between the bottom member of the frame and horizontal support (22) below is a central bellows between two vertical telescopic pillars, which allow the frame to tilt about a horizontal axis (24). This tilt is controlled by an external sliding psiton (56). Under the belt is a pipe connected to a pressure vessel (62) with a valve (72) connected to a compressed air supply. This is controlled by a servo system so that the piston controlling the tilt of the roller around which the belt passes is operated in response to a change in pressure inside the vessel. The system can also be used to control the discharge of an organic solvent corresp. to the pressure inside the vessel.

Title: Brake monitoring circuit for tracked vehicle - includes braking curve transmitter and uses reference valve synchronised to braking curve with lead signal
Inventor: LANGE HANS-ARMIN DIPL ING
IPC: B61L3/12
Filed: 1980-10-01
Abstract: The brake monitoring circuit for a manually driven tracked vehicle, which is fitted with a braking curve transmitter. The braking curve is preset to a given braking delay. The action points along the line are spaced given distances apart. The monitoring circuit transmits a signal to denote the permissible reference speed to achieve the targeted braking of the vehicle. The reference value transmitter (SG) can be switched in synchronism with the braking curve transmitter (B) from a basic setting. An output signal corresponding to a reference speed leads the output signal of the braking curve transmitter by a given time interval. A comparator produces an output signal, which is fed to an indicator unit when the actual speed does not fall below the reference speed.

Title: Single sided coating of metal strip with molten metal or alloy - esp. zinc coating of steel strip which travels over convex guide rolls partly immersed in zinc bath
Inventor: UMLAUF NORBERT
IPC: C23C2/06
Filed: 1980-12-19
Abstract: A metal strip (I), made esp. of steel, is preheated in a furnace, and is then fed round at least one guide roll which is partly immersed in a molten bath (II) of a metal or alloy, esp. molten Zn, so the strip (I) is only coated with metal (II) on its underside. The roll has a convex profile so the strip (I) assumes a trough-shaped profile while travelling through the bath (II). The coating plant pref. uses two convex guide rolls sepd. by a gas deflector baffle; and gas is blown across the upper surface of the moving strip to keep metal (II) off the upper surface of the strip. A relatively thick coating (II) can be obtd., which has a similar thickness to that obtd. when a strip is coated on both sides and the height of the bath (II) can be accurately adjusted.

Title: Exhaust system for vehicle - has reactor producing hydrogen for re-cycling to reduce exhaust pollution
Inventor: ATTERMEYER WERNER ING GRAD
IPC: F02M26/57
Filed: 1980-12-22
Abstract: The exhaust system has part of the exhaust gases flowing into a reactor (10) on their way to the exhaust pipe (4) from the engine (1). The reactor contains a platinum wire (17) between two pins (15,16) connected to the vehicle's battery (18) via a switch (22). A toroidal chamber (25) lies between carburettor (2) and engine and passes the output of the reactor into the fuel/air inlet line (3) leading to the engine. The platinum wire attains temps. above 1200 degrees C and dissociates the exhaust gases to give a gas containing hydrogen, which passes back (via a butterfly valve (29)) into the fuel/air inlet. The advantage lies in reducing the harmful products in the exhaust.

Title: Data transmission system and method for transmitting data
Inventor: YASUMOTO SEIICHI
IPC: H04L12/423
Filed: 1981-04-02
Abstract: A central station (CST) and a transmission station (TST) are connected in cascade via a serial transmission line and form a main data path system in the form of a loop. The central station (CST) controls the whole system en bloc. The system allows the transmission station (TST) which has a request for data signal transmission to transmit a data signal on the basis of a normal data retrieval signal. However, only the station which has transmitted the data signal on the basis of the preceding normal data retrieval signal is able to transmit data signals again on the basis of a repetition data retrieval signal. <IMAGE>

Patent DE-3123231-A1 (DE)
Title: Semiconductor device and method of producing it
Inventor: NISHIZAWA JUN-ICHI
IPC: C30B19/04
Filed: 1981-06-11
Abstract: In a semiconductor device made of a group II-VI material, a substrate crystal is pulled from the liquid phase using the differential temperature technique, while a regulated vapour pressure is maintained for the element of group VI. This method reduces the concentration of vacancies and other defects which act as donors, compared with the concentration of the p-type impurities introduced by diffusion. Semiconductor devices which emit a light of very short wavelength as light-emitting diodes can be produced by this method.
