Title: Complete knee joint prosthesis - permitting specified flexion and rotation by ball joint
Inventor: MAAZ BURKHARD DR
IPC: A61F2/38
Filed: 1979-07-11
Abstract: Endo-prosthesis for the knee joint consists of a tibia part with a stem to be implanted in the shinbone and carrying a condyle, and a stem to be implanted in the thigh bone, carrying a two-part socket. The ball joint formed by them has a limited flexion, pref. up to 120 deg., and a limited rotation, pref. of plus or minus 15 deg. A guide groove in the condyle, which faces a slot on the socket, carries balls to limit the motion. A grubscrew runs across the two socket parts. Both socket and condyle are pref. coated with PTFE. The additional final possible rotation prevents premature loosening of the implanted stems.

Title: Gas-tight rotary stopcock - forms seal by higher pressure in housing
IPC: F16K5/04
Filed: 1979-07-28
Abstract: The rotary-disc-type stopcock is gastight, the seal being effected by pressure in the stopcock housing, e.g. of gas, higher than that in the piping. Thus the prod. cannot penetrate into the housing, and a clearance volume is formed. The disc can be of PTFE-cpd., with low friction and high elasticity. Any leak is detected by a pressure drop in the housing, shown on an indicator or setting off a warning signal.
Patent DE-2931878-A1 (DE)
Title: Speed control circuit for async. motor - is for even motor rotation at low rates and uses current converter without intermediate DC circuit
Inventor: THURNER WALTER
IPC: H02P23/24
Filed: 1979-08-06
Abstract: The circuit uses a current converter supplying the AC for the motor, the frequency of which controls the rotation rate of the motor. A comparator (1) provides a control signal to a voltage/frequency converter (6), dependent on the difference between the signal from a tachogenerator (16) monitoring the actual motor rotation and a reference signal representing the required speed. A commutation frequency generator (8) responds to the output of the voltage/frequency converter (6) synchronised with the network supply, to provide six commutation signals with relative phase offsets of 60 degrees. These signals are used to control load switches (11), via which each stator winding (15) of the motor (M) is coupled to all three phases of the network.

Abstract: The method of forming connections with the windings of a transformer, uses connectors (6) made as metal stampings, which are inserted into cavities through the flanges (2) of the former (1) carrying the windings. Each connector has a thin stem (3) at one end, to which the ends of the windings are connected by e.g. soldering, and a wider portion at the other end, for crimping around the ends (9) of external connecting wires. Each cavity has a shoulder (8) against which there is located a resilient tongue (4) projecting from the central part of the connector. The cavities terminate in a larger chamber (10) divided by a central partition (16) into two parts. Connection with the winding ends can be made in these two parts, and both can be filled with an insulating substance.
Patent DE-2937066-A1 (DE)
Inventor: PALETTA BENNO PROF DR PHIL
IPC: F04B49/00
Filed: 1979-09-13
Abstract: The metering apparatus for small volumes of liquid in the milliliter and microliter range comprises a piston/cylinder system driven by a direct-current motor. The piston stroke is measured by means of an optical path-length measuring system. For this purpose, a slide-rule pulse scale provided with a regular line grid is affixed to the piston. The light from a light transmitter passes through the slide-rule pulse scale and a stationary scanning plate which likewise is provided with a regular line grid, and to a light receiver. The pulses of the light receiver are digitalized in a pulse conditioning circuit and fed to a counter adapted to be preset by means of a coding switch. The counter position acts upon a braking and rotative-speed regulating circuit in such a way that regardless of the preset desired value of the rotative speed the speed of rotation of the motor is reduced to a small value as the final value is approached. As soon as the preset volume has been metered and the counter has reached the zero position, the motor is brought to a dead stop through a motor-control logic circuit with the aid of a reverse voltage. During the stopping process the no-load voltage of the motor is measured by means of a zero-voltage comparator at regular intervals. A pulse monitoring circuit serves to measure and regulate the piston-stroke speed and to turn off the motor in case of a mechanical defect. Motor and electronic systems are supplied with current from dry cells or storage batteries, a power supply being optionally provided to charge them.

Title: Goods stack shrink-wrapping method - involves gas current directed at overlapping area during shrinking of second sheet section
Inventor: KLUEPFEL OLAF DIPL ING
IPC: B65B53/06
Filed: 1979-11-02
Abstract: The method is used for fully wrapping piece goods, particularly in stacks, in shrunk-on sheet material. A first section of sheet is shrunk over the top and part of the sides of the stack, which is then turned through 180 deg. to allow a second section, overlapping the first, to be shrunk on. At the overlapping area, a current of gas aimed at the first section underneath is directed at the second one during or after the second shrinking operation, and typically shortly before completion of the latter. Compressed-air can be used for the gas current, its duration and local intensity being adjustable.

Title: Schottky diode with specified doping concentration - achieving high-ohmic semiconductor zone on low-ohmic semiconductor zone
Inventor: KASPER ERICH DR
IPC: H01L29/872
Filed: 1979-12-15
Abstract: The Schottky diode has a low-ohmic semiconductor zone (1) adjoining a thinner intrinsic or high-ohmic semiconductor zone (2). A Schottky contact is formed on the intrinsic or high-ohmic semiconductor zone. The doping concentration of the high-ohmic zone is determined by the thickness of this zone. If the diode is used in a microwave mixer then the working point and the power of the local oscillator are chosen to lie below a given figure. The low-ohmic zone may be the substrate for an epitaxial intrinsic or high-ohmic semiconductor zone.
Patent DE-3007136-A1 (DE)
Title: Alcohol concn. measurement - by dipping semiconductor sensor in non-conductive liq. mixed with test fluid
Inventor: EIBL VOLKER DIPL ING
IPC: G01N33/497
Filed: 1980-02-26
Abstract: Alcohol concn. in a medium, e.g. in blood, is measured by dissolving the medium in an electrically non-conductive liquid (bidistilled water) in a predetermined ratio. A semiconductor sensor is immersed in the solution to a given depth at a given temperature and its readings are compared with figures of a calibration curve, obtained by dipping the sensor into a solution of the non-conductive liquid with a known concentration of alcohol. This eliminates the difficulties in the calibration of conventional alcohol sensors as regards constant pressure and temp. conditions.
