Title: High speed async machine with squirrel cage rotor (s) - has specifier rotor parts dimensions for desired flux generation
Inventor: SAPPER JOERG
IPC: H02K17/16
Filed: 1975-01-22
Abstract: The high speed asynchronous machine has at least one squirrel-cage rotor, constructed from a massive inner part of magnetisable steel and an outer, axially subdivided part also of magnetisable steel. The outer part (3) has minimum radial dimensions measured from the rotor surface to the outer squirrel-cage outer circumference, and maximum radial dimensions over the inner squirrel-cage, so chosen that during synchronous running at least one half of the rotor yoke flux per pole, at the stator filled exited by the machine rated voltage, closes over the inner part (2) as a consequence of the outer part saturation.

Title: Camera lens focus detecting system - with simple electronic circuit simulating focusing mechanism of human eye
Inventor: TAKEDA HIDEOMI
IPC: G02B7/36
Filed: 1975-02-07
Abstract: The system detects the focus of an image in a plane located at a variable distance from a lens in a camera. A focus sensor, e.g. using CdS cells, generates an electrical signal dependent on the focus in the image plane and having an extreme value at optimum focus. A memory stores the extreme value and a comparator compares the stored value with the value occurring when the lens is adjusted. When the two values are identical an indicator shows that the lens is correctly focused. The memory may be a capacitor with a comparator which comprises a differential amplifier, a threshold circuit, a light emitter and an amplitude limiting circuit.

Title: Programming circuit for ECL ROM with transistor - has fuse link cells and switching circuit coupled to line selection to provide switching
Inventor: SCHARBERT JUERGEN DIPL PHYS
IPC: G11C17/16
Filed: 1975-02-07
Abstract: A programmable ECL ROM has a switching circuit for time selection that allows a sufficiently high current to be applied to a resistance fuse link for memory cell setting. Each time (26) of a memory matrix consisting of a transistor and fuse is supplied by a selection circuit consisting of three control transistors (TR1, TR2, TR3) with a common collector resistance. The resistance and an emitter follower resistance of a transistor (RE1) are coupled to a supply voltage (VCP) the transistor (T1) and a parallel transistor (T2) together with resistances (RE1, RE2) provide two constant current sources. In operation one current source is active during the normal selection process and the higher current applied when memory cell programming is required.

Title: Lock for stacked drawers in cabinet - has actuating vertical rod guided only by two brackets
Inventor: REIS ANTON
IPC: E05B65/463
Filed: 1975-02-25
Abstract: The locking arrangement is intended for stacked drawers arranged into a common cabinet. One drawer can be pulled out, while the others remain locked. The locking rod (35) moves at right angles to the direction of movement of the drawer (16). This rod is guided by guides (30) held on the cabinet or frame (17). The guide has a guide slot (34) for the locking rod and a hooked rack which is engaged by the pinion held on the rod. The guide slot can have a local contraction, e.g. in the middle of the slot. This slot also has reinforced edges (39). The advantage of the mechanism is that it has only two guides and no brake system is needed.

Title: Anti-static floating cover seal for bulk storage tanks - with plastic foam in both cover and seal hose with graphite filler
Inventor: AVERDIEK WALTER GEORGSMATIENHU
IPC: B65D88/50
Filed: 1975-03-22
Abstract: A storage tank for liquid media has a floating cover which is filled with plastic insulating foam and has a peripheral seal against the cylindrical tank walls. The seal consists of a perforated hose which is bonded into a semicircular rim of the cover and is also filled with plastic foam. To make the foam of both cover and seal conductive for static electricity it is filled with particles of graphite. This prevents the accumulation of static electricity by friction of the seal against the wall and of the fluid against the cover, which may produce explosion if the fluid is oil, petrol or a liquefied light hydrocarbon. The hose can be easily cut to length to make it suitable for different tank diameters.

Title: Sprung coupling for windscreen wiper arm - with axially interlocking cams disengaged by axial pressure to set wiper arms
Inventor: BAUER KURT
IPC: B60S1/34
Filed: 1975-07-03
Abstract: The end of the wiper stub axle (10) is fitted with a special cam (13) bolted to the axle by a securing nut (14) and located on a conical, splined fitting (34). The cam is located inside the hollow head of the wiper arm (20) and is pressed into contact with a cam surface (31) at the bottom of the head, by an axial spring (15). This couples the wiper arm and stub axle together. The coupling is released by axial pressure on the head to allow the head to be adjusted. The system allows the operator to press the head and release the coupling so that the position of the head w.r.t. the axle can be adjusted even with the wiper arm located in a slot under the windscreen for improved parking.

Title: Water removal from glass objects leaving no stains - using row of tanks contg. organic solvent immiscible with water
Inventor: GOLLMICK HANS-JOACHIM DR
IPC: F26B5/00
Filed: 1975-10-25
Abstract: Water is removed from the surface of an object, esp. glass, by immersion in a boiling dewatering bath (1) of solvent immiscible with water and contg. surfactants. The glass is then rinsed in pure organic solvent baths (2) to remove surfactants. The vapour is condensed and recycled.

Inventor: VADASZY PAL DIPL ING
IPC: G07B15/00
Filed: 1976-07-12
Abstract: The device for identifying the vehicles entering and leaving a vehicle pool comprises transmitters built into the vehicles and a stationary receiver provided with an antenna. The transmitters have a modulator (2) connected to a carrier-frequency oscillator, a code signal transmitter (4) connected to the control input of the modulator and an oscillator (3) connected to the input of the code signal transmitter (4). Depending on the identity number of the vehicle, the corresponding code signal, introduced by a long start pulse, is formed by the code signal transmitter (4). The receivers (5) have a demodulator in the carrier-frequency component which is connected via an <<AND>> circuit (7) to a recording and evaluation device (6) and to a sampling circuit to generate sample signals. This sampling circuit controls the generation of the sampling signals. It reduces the requirements for synchronous operation of transmitter and receiver and enables the manufacture of less accurate and less expensive transmitters. <IMAGE>
