Patent DE-3043256-A1 (DE)
Title: Telephone system signalling circuit - uses AC with synchronisation circuit timing control pulses to coincide with zero voltage crossover
Inventor: FINK GERHARD
IPC: H04M19/02
Filed: 1980-11-15
Abstract: The system uses alternating current on the conversion line of a telephone switching system. A signalling voltage generator (GEN) has its output connected to the conversation line. A shaping circuit (REU) modifies the alternating voltage provided by the generator, and produces a rectangular voltage with pulses in synchronism with the alternating current. A logic current synchronises the control signals which are produced, with the passing through zero of the reshaped alternating voltage. The signalling voltage generator comprises a Wien-Robinson bridge oscillator. The generator (GEN) may be coupled to the conversation lines (A,B) via a switchable pre-amplifier (VOV), a voltage doubler, (SPV) an isolating transformer (T1) and a transmission amplifier (SEV).

Title: Machine tool for truing straight pipes with high cutting speed - has speed regulator operating changeover switch for max. and min. cuts
Inventor: SKAROHLID OTAKAR DIPL ING
IPC: B24B27/06
Filed: 1980-12-29
Abstract: The workpiece is kept in a fixed position and a rotating cutting disc removes the material from the surface. The cutting disc removes the min. of material during the first few rotations around the workpiece to form a starting slot. This facilitates the increase in the linear speed of the cutting disc to improve the rate of cut. A speed regulator (522) is controlled by the min. and max. cuts by the disc. The speed regulator module operates a change-over switch (506). There is a pick-up module for the speed and a counter (505), which actuates the change-over switch to change the position of the switching element (560).

Patent DE-3120008-A1 (DE)
Title: Rowing mechanism
Inventor: RECKENDORF HANS
IPC: B63H16/04
Filed: 1981-05-20
Abstract: In summary, it can be said that the invention with the designation "rowing mechanism" relates to oars and sculls with a blade movably attached to the shaft. The blade is held in the favourable right-angled position relative to the longitudinal axis of the boat by a parallel linkage. The invention enables both forward and backward thrust forces to be transmitted to shaft and blade by a rotatably mounted handle as well as torque to be transmitted by universal joint to the blade, pivotably mounted around the shaft end about its longitudinal axis, even over an angle between shaft and blade. Here, the shaft is carried in a rowlock which permits both the shaft movement required for rowing and the force transmission to the boat and can also absorb the thrust forces coming from the boat and acting axially to the shaft in the direction of the handle. In this arrangement, the bearing points of the handle are configured in such a way that reliable guidance of the blade during the stroke is possible.

Title: Fireproof door with a door leaf of flush or shiplapped design I
Inventor: PODSZUCK KARL ING GRAD
IPC: E06B5/16
Filed: 1981-05-23
Abstract: The subject matter of the application is a fireproof door with a door leaf which is of flush or shiplapped design, has a large door surface on the hinge side (8) and on the side (9) opposite the latter, and butts, on the side opposite the hinge side, against a leg of a case which is designed essentially in the form of a Z or a W. The door-leaf abutment (10) on the side opposite the hinge side is arranged in a plane between the door surface on the side (9) opposite the hinge side and that on the hinge side (8) or in the plane of a hinge-side abutment (15). By positioning the case abutment towards the centre of the door, deflection of the fire gases in the direction of the door surface is suppressed. As a result, complex measures to prevent the border zone of the door surface heating up on the side directed away from the fire can be dispensed with. <IMAGE>

Patent DE-3218550-A1 (DE)
Title: Machine gun
Inventor: KOINE RICHARD ING GRAD
IPC: F41A7/08
Filed: 1982-05-17
Abstract: For an exclusively power-operated machine gun having two weapons connected next to one another in a common weapon housing, the object is to provide a shot-controlling safety device by which, in the event of any fault not leading to ignition, a power-operated weapon drive is to be cut off automatically in a jolt-free and shock-free manner, with the breech being secured in position. The object is achieved in that each weapon comprises a power-operated chain drive (5) of a breech assigned to each weapon and a shot-controlling device (3) which acts jointly on the chain drives (5), monitors the safety state of the breeches (6) and is controlled in dependence on the gas pressure generated by the shot, the power supply being positively interrupted continuously with a delay by the shot-controlling device (3) in the event of any fault not leading to ignition. If the breech (6) can be released directly as a result of the firing energy by means of a device (4), the movement ratios outside a catch interval (37) are determined by a driver (15), whilst a breaker cam (9), in cooperation with two switch levers (13), a rotary slide of the shot-controlling device (3), the conditions of the loading space (72) and the position of the trigger, decides on "stop firing" and "free to fire". <IMAGE>

Title: Heat exchangers and method of de-icing the same
Inventor: KOELLER DIETMAR
IPC: F25D21/06
Filed: 1982-11-18
Abstract: Heat exchangers which are operated outside in temperatures below freezing point tend to form ice on the outsides of the exchange elements (exchange plates 10), as a result of which the efficiency of the heat exchanger is restricted. For this reason, the invention proposes a heat exchanger made from elastically formable exchange elements (exchange plates 10) whose ducts (12), through which a heat exchange medium flows, can be elastically deformed, for the purpose of mechanically removing the ice, by a rising pressure therein. The method of doing this is to interrupt the circuit of the heat exchange medium flowing through the ducts (12) in conjunction with simultaneously uninterrupted feeding of further heat exchange medium to the ducts (12). <IMAGE>
