Title: Self-monitoring amplifier for high voltage capacitive measurement - has voltage comparator comparing input and output voltages and revealing nature of failures
Inventor: RUF DIETER DIPL ING
IPC: G01R15/06
Filed: 1979-01-22
Abstract: A self-monitoring measurement amplifier for a capacitive voltage measurement of high voltages has a capacitive voltage divider connected across the measured voltage and driving the amplifier input. The input is isolated from the output and supply connections which are also mutually isolated. It enjoys a high degree of reliability despite the high failure rate of electronic components. If a failure does occur an unequivocal indication is provided of its origin and nature. The circuit contains a voltage comparator comparing the amplifier voltage input with its output voltage. The comparator consists of a differential, eg. operational, amplifier, or forms part of a microcomputer. In the latter case the amplifier circuit input and output stages contain an A/D converter and a D/A converter respectively.

Title: Capstan lathe for machining long workpieces - has guide bushes and pneumatic clamp in rotating head for bar pushed up to stop
Inventor: STADLER HERMANN
IPC: B23Q7/04
Filed: 1979-02-23
Abstract: A capstan lathe which handles long workpieces has a feeding device which pushes the workpiece (5) through the hollow spindle against a stop (17) mounted on the rotating head (7). The required machining operations are carried out by the tool (18). The head (7) is rotated so that the bar can be pushed through the guide bush (8) until it abuts against the fixed stop (15). The bar is then held by a pneumatic clamp whilst the machining is completed. After machining, the head is rotated once more to enable the workpiece to e ejected downwards.

Title: Dog food additive to impart a carrion odour - consisting of comminuted gastrointestinal offal esp. ruminant stomach mixed with fat esp. pork lard as preservative
Inventor: HANS WALTER
IPC: A23K50/48
Filed: 1979-04-14
Abstract: Comminution of the gastrointestinal material is advantageously carried out in a cutter of the type used in the prodn. of sausages. The preservative effect of the fat can be increased by including salt in the mixture. The mixture is advantageously packed in a tube in order to facilitate the measuring out of small amounts of the composition and to minimise contact of the composition with air. Addition of a small amount of the additive to normal dog food renders it particularly attractive to dogs (which are known to be particularly attracted by the smell of carrion) while keeping odour to a tolerable minimum.
Patent DE-2921741-A1 (DE)
Title: Film of PVC for sealing concrete structure - has smooth projective ribs enclosing honeycomb cells rolled from film
Inventor: LESCHUS GERD
IPC: E04B1/66
Filed: 1979-05-29
Abstract: Breadth of the cross-sectional profile of the ribs formed on a continuous run of synthetic film, such as PVC or synthetic rubber, for sealing a concrete structure, diminishes continually from a plane level with the surface of the film, to the crest of the rib. The ribs engage in the surface of the concrete. They stand vertically on the film and their profile is symmetrical to their lengthways central plane. The profile is a trapezium with a convex crest. Ribs are in sections which enclose cells and blend into each other solidly. For pref. the cells are hexagonal and they have their long axes parallel to the direction fo extrusion the ribs are embossed by rollers before the synthetic material has set. Provides a sealing film which since the ribs have no projection does not allow the formation of pockets through which ground water can penetrate, so that the passage of water from leaks is prevented.

Title: Knitting machine Jacquard device - with each pattern sinker fitted with permanent magnet coil and pole shoe mounted on shaft and held by bars on coil periphery
Inventor: ROSE WOLFGANG DR ING
IPC: D04B15/84
Filed: 1979-09-08
Abstract: Knitting machine Jacquard device having an auxiliary bed in which diposed pattern selecting sinkes displaced by pulses derived from a store has each of the sinkers provided with a permanent magnet, coil and a pole shoe which are disposed on a shaft. Magnets, coils and shoes are arranged along the shaft and held in positin by bars disposed about the periphery of the coils. For selection of the sinkers the magnetic field of the permanent magnets is weakened with the aid of the pulses derived from the store. Weakened field allows the biasing spring to displace the sinkes into their selected positions. Sinker selection time is reduced.

Title: Transistor pulse generator e.g. for interference suppression - uses time constant circuit providing variable level signal fed to threshold circuit
Inventor: TANAKA KOUICHI
IPC: H03K5/04
Filed: 1979-10-03
