Patent DE-2347169-A1 (DE)
Title: Measurement and grading method - designed for temperature coefficient of resistance of voltage independent resistors
Inventor: POETZLBERGER HANS WERNER DIPL
IPC: G01R27/02
Filed: 1973-09-19
Abstract: The method is intended to maintain a specified tolerance range around the value of TCR=O. A sinusoidal voltage of a certain value is applied to the resistors; harmonic distortion expressed as attenuation is measured, and the TCR is determined in accordance with a specified equation; resistors whose harmonic distortion is lower than the value corresponding to the maximum permissible TCR are accepted; the TCR specified range lies between 200 and -200 ppm/deg.K. The invention offers a quick routine testing method that can, in fact, be constructed to work automatically, and up to ten resistances or resistors can be measured every second.

Title: Communication system for vehicles - each vehicle has sender and receiver, whose power is controlled as function of vehicle speed
Inventor: WEISSER WERNER
IPC: G08G1/16
Filed: 1973-10-02
Abstract: The transmitter and receiver power is increased at lower speeds, and reduced at higher speeds. Each vehicle has a tachometer which supplies the speed signal. A controlled attenuation pad is inserted between the transitter and receiver on one hand, and the antenna on the other one. The speed signal, together with other possible signals, is applied to this attenuator. The antenna may have a directions characteristic, controlled by the speed signal. A microphone is connected to the transmitter and an acoustic transducer to the receiver. A signal generator may be coupled to the transmitter for limited signal number transmission to an associated optical or acoustic receiver.

Title: Constant velocity coupling for angled shafts - has two shaft ends connected by intermediate coupling forks on independent bearings
Inventor: HAARMANN WALTER DIPL-ING
IPC: F16D3/38
Filed: 1973-10-08
Abstract: The intermediate links are of a hinge type and can pivot about the hinge point of the coupling. The bearing in the centre of the hinge point is a spherical type with a sphere connected to one fork and the socket connected to the other. The spherical link is eccentrically mounted between the fork links and there are support arms bent inwards towards the hinge point. An alternative arrangement has bow shaped side pieces opposite one another instead of the intermediate forks. In this case the hinge is at the point of joining of the bows.

Title: Exhaust gas pollutant separator - has water spray cloud zone directly after heating boiler, with gas recirculation to combustion space
Inventor: HUTHMANN OTTO
IPC: B01D53/34
Filed: 1973-12-03
Abstract: Pollutants are separated from waste gases by a washing process, and the gases are passed, directly after leaving the heating boiler, through a zone with an artificially produced cloud, preferably of sprayed water, to which binder chemicals are added. After leaving this zone, the gases are passed back through a channel into the combustion space. Behind their last chamber or trickling plant, the gases are directly passed into the atmosphere. In a container, an upper water atomizer and a lower trap are fitted, and the waste gas channel is conducted in at one side, and out the other, of the chamber. The apparatus may be used for household heating, motor vehicle, or industrial waste gases.

Title: Voltage multiplier with chain of four diodes - has capacitors converting AC input into doubled and quadrupled outputs
Inventor: HUBERT KALINOWSKI HAMBURG
IPC: H02M7/10
Filed: 1974-01-19
Abstract: The voltage multiplier has the a.c. input signal applied over two input capacitors to a chain of four diodes, all in the same conduction direction. The first input terminal is coupled over both capacitors to two points in the diode chain, and the second input is connected to the centre of the chain. The two output capacitors bridge the halves of the chain and the three output terminals are taken from the ends and the centre of the chain. The voltage between one end and the centre is double the input and between the two ends, four times the input. By replacing one pair of diodes with a single diode, three times the input can be obtained.
Patent DE-2414932-A1 (DE)
Title: Tank recycle filter - having cartridge mounted on threaded nipple which projects into tank but allows oil to drain
Inventor: KRUEGER HEINZ
IPC: B01D27/08
Filed: 1974-03-28
Abstract: Recycle filter for tank installations consists of a replaceable cartridge which is screwed onto a threaded nipple. This projects into the tank and has a flat surface on a flange which seals against the tank when the cartridge is screwed on. Rotation of the nipple when the cartridge is being screwed on or off is prevented by a bar through it, which also prevents it dropping into the tank. When the cartridge is removed, the nipple drops onto this bar and opens a hole on the dirty fluid inlet port, allowing fluid in this region to fall into the tank. System of use where liquids, such as oil, are filtered on a recycle system.

Title: Centrigufuge for separating powder/fine-granules from an airstream - two coaxial cones rotate in the central of three compartments
Inventor: GONARD ANDRE
IPC: B07B7/083
Filed: 1974-08-14
Abstract: The centrifuge is envisaged for use in a plant where air currents are used to convey grains and powders from place to place. At the destination, the solid is separated and the air re-circulated. The laden air is brought into the middle compartment of the separator, where two coaxial cones are rotating. The solid particles, moving outwards between the coneS, pass down into a storage receptacle which forms the lower compartment; the air moves up, under suction, through the inner cone and its chimney, into the upper compartment and out for re-circulation. A valve controls the air pressure in the upper compartment at the required reduced level.

Title: Standby or emergency electrical supply - uses filter circuit to provide power during transition period when normal supply fails
Inventor: UDVARDI-LAKOS JANOS DIPL ING
IPC: H02J9/06
Filed: 1974-09-27
Abstract: The electrical supply equipment is designed to provide power during the breakdown of normal supplies, the transition from one supply to the other being uninterrupted. The design is intended to reduce the losses due to two stage conversion from battery d.c. to output occurring in some systems. Any pause between supply breakdown and standby operation is catered for by the energy stored in a filter in series with the load. Two or three phase systems are accommodated, the standby supply being fed into the load circuit when signals derived from load circuit transducers are allowed to pass to a d.c. powered oscillator.

Title: Black board washing and cleaning device with rotating roller - horizontally moving roller traverses black-board surface under constant light pressure
Inventor: REIF GEORG
IPC: B43L21/00
Filed: 1975-01-02
Abstract: A wall mounted blackboard washing or cleaning device has sets of toothed racks mounted above and below the blackboard which engage into open wheels mounted on the vertical roller type washing and cleaning device. A spring is used to ensure a constant light contact pressure between the cleaning roller and the blackboard surface cleaning rubber strip. The cleaning roller supplies water to the blackboard and the rubber strip following closely behind it scrapes the excess water off into a trough below the device. On its return to start travel of the board, the spring tension is released thus ensuring that the chalk laden roller does not contact the board surface. Water sprays then clean the roller.

Title: Power transformer with rectangular core - has coaxial windings to occupy minimum space and resists internal forces
Inventor: WEBER WALTER
IPC: H01F27/28
Filed: 1975-02-25
Abstract: This power transformer has a core that is virtually rectangular and has coaxial windings which, although they have a modified shape, are also approximately rectangular. The sides of the outer windings are curved to ensure that the tensile forces under short-circuit conditions remain below the limit of elasticity. Other spacing pieces are provided between the windings, core and casing to support and restrict the windings as well as provide damping in case of oscillation. This arrangement enables the transformer to be made in a compact form.
