Title: IC engine ignition circuit with extra transistor - has precise limiting of current flowing through output transistor and transformer primary
Inventor: JUNDT WERNER DIPL ING
IPC: F02P3/045
Filed: 1976-09-21
Abstract: The ignition circuit, for an IC engine, has the control transistor base (9) connected via the emitter/collector path of an auxiliary transistor (11) to the emitter of the output transistor (7). The auxiliary transistor collector is connected to the control transistor base. The auxiliary transistor base is earthed via a diode (12) and resistor (13). The advantage lies in being able to precisely limit the current flowing through the output transistor base/emitter junction and therefore the current flowing via this transistor collector/emitter path through the transformer primary winding.

Title: High pressure gas bottles cleaning machine - performs sand blasting of end of steel bottle and bottle end is enclosed in hood
Inventor: LINOW WERNER
IPC: B24C9/00
Filed: 1976-10-30
Abstract: Steel bottles used for storing high pressure gases such as acetylene have identification marks and other data stamped on the upper end of the bottle. After years of use this information becomes illegible due to accumulation of dirt so that the surface must be cleaned. The bottle is mounted vertically in a cradle which is swung to the horizontal position by the pneumatic jack and the end pulled inside the hood. The pipe directs a stream of air containing sand or other abrasive material over the end of the bottle which is simultaneously rotated about its horizontal axis by the motor driving the rollers.

Title: Feeding oxygen into activation basins - using spray nozzle reaction impulse to move gasification unit over floor
Inventor: KROETZSCH PETER DIPL ING DR
IPC: B01F15/00
Filed: 1977-01-29
Abstract: The process introduces oxygen and forms activated sludge suspension in activation basins. The reaction impulse occurring with self-priming or compressed air-operated spray nozzles or ejectors is used to move the gasification unit over the floor of the activation basin. Turbulence generation in the sludge can be aided by rotary compressor bodies. The design ensures that the ventilation units necessary for oxygen introduction can also be relied on to keep the sludge in suspension.

Patent DE-2705674-A1 (DE)
Title: Hydraulic system control valves - include sealing valves switched parallel to conduits of valves or cylinders
Inventor: DITTMANN CHRISTIAN
IPC: F15B13/02
Filed: 1977-02-11
Abstract: The pressure medium - or control conduit of a valve or cylinder (12, 13, 14) within the system each have a parallel sealing valve (11). For a hydraulically actuated valve, the sealing valve releases the pressure medium when there is low pressure, or a low medium flow. With high pressure, resp. a high flow, the sealing valve closes. In a working system having several three position cylinders with three pressure chambers next to each other, only the central chamber is charged with pressure medium. The sealed conduits of the outer chambers (12', 13', 14') each have a sealing valve acting in the same way as above. The medium conduit of each valve has a sealing body, which is pressed away from a sealing surface by a spring against the direction of flow.

Title: High performance windscreen wiper - has double blade on common holder to produce suction between blades and windscreen with connection to low pressure source
Inventor: KALKHOFF HEINZ
IPC: B60S1/48
Filed: 1977-02-11
Abstract: The high performance windscreen wiper has two parallel wiper blades on a common holder, with the ends of the blades sealed to form a closed space when placed on the windscreen. The space is linked to a low pressure supply so that the suction enhances the blade pressure and prevents the blade from leaving the windscreen. The wiper provides effective wiping for high speed vehicles including aircraft. The cross section of the enclosed space is either U or V shaped. A pipe (30) on the rear of the wiper connects the space to the vacuum line via a flexible pipe along the wiper arm.

Title: Weighing control for food slicing machine - generates digital signals to control slice thickness should weight deviate beyond set limits
Inventor: FERRI I RAFAEL DIPL ING
IPC: B26D7/30
Filed: 1977-02-18
Abstract: Control system for cutting and weighing block-like food products, esp. cheese, regulates the thickness of the cut sections in relation to analogue signals generated by the weighing machine. The analogue signals are digitised in a converter and fed to a calibrating unit with a read-out display. The weighed out portions pass to a sorting unit which separates out those portions which exceed or fall short of preset weight limits. The digital signals from the calibrating unit are fed to a discriminator which only allows to pass those signals that correspond to weights between the boundary limits. These signals pass on to control the servo-motor for adjusting the thickness of cut.
Patent DE-2709156-A1 (DE)
Title: Acceleration indicator device generating electrical signals - has Hall generator or field plate mounted adjacent deflectable permanent magnet
Inventor: WUNDER DIETER
IPC: G01P15/105
Filed: 1977-03-03
Abstract: An acceleration indicator device generates electrical signals as a result of deflection, by an accelerating force, of a permanent magnet (4) relative to a magnetically controllable semiconductor device (6). A permanent magnet (4) is suspended by a leaf spring (3) from a surface (1). The spring may be deflected by means of an accelerating force. Beneath the magnet in its quiescent position, a magnetically controlled semiconductor device (6) is affixed to a lower surface (2). The semiconductor device, which may be a Hall generator or a field plate, generates a signal indicative of its horizontal relationship with the magnet. After amplification, the signal may be employed to actuate a moving coil instrument. Two semiconductor devices may be employed to sense movement of the magnet in orthogonal directions.
Patent DE-2711099-A1 (DE)
Title: Ski brake which can be locked in braking position - has rack and pinion mechanism connected to pivoted blades via rod, and catch with tip which can engage rack hole
IPC: A63C7/08
Filed: 1977-03-14
Abstract: The ski brake consists of two blades (24) which are mounted one on each side of the ski (1) on the ends of a transverse shaft has a pinion which engages a rack (6) connected to a rod (12). The rod is connected to a spring which pulls the blades to the vertical position. The spring is released by the removal of the ski boot from the ski. The blades can be held in the vertical position when still being worn, by a catch (20) with a tip which fits into a hole (29) in the rack (6). This enables the blades to be held in the braking position so that when climbing steep slopes the skier is prevented from slipping backwards.

Title: Glass melting furnace giving improved quality glass - part recycle of excess in working vat to adjacent melting section or clarifying chamber, to remove bubbles and obviate component evapn.
Inventor: PIEPER HELMUT DIPL ING
IPC: C03B5/187
Filed: 1977-04-27
Abstract: In operating a glass melting furnace with a melting section adjacent to a workinv vat the amount of glass flowing into the working vat is maintained at a higher level than the mat. extracted from the vat, e.g. 3 to 10-times greater. The excess is recirculated by a connecting duct into the melting section or into a separate clarifying chamber. Process removes any bubbles introduced by the extraction operation and prevents quality alterations by surface evapn. of boron, lead or fluoride contents. Glass of better and more uniform quality is obtd. independent of the loading and type of operation. The furnace is easy to build and to operate.

Title: Water or wind powered turbine - has vertical drum carrying blades with conical inlet on top and open bottom
Inventor: STEINLE ANTON
IPC: F03D1/04
Filed: 1977-05-13
