Patent DE-2504393-A1 (DE)
Title: Lock key anti loss warning - has flashing light or buzzer operating when key withdrawn until correct storage
Inventor: BELLARTZ HUBERT
IPC: E05B19/00
Filed: 1975-02-03
Abstract: The car or house door key is fitted with a miniature battery which is cut off when the key is inserted. When pulled, the battery operates a flashing light and produces audible pips until it is inserted in a small case attached by a chain to the trousers or to the wall. When the car key is inserted in the ignition lock, button is depressed by the dashboard. The spring in the housing is compressed and the contacts are broken. When the key is withdrawn, the contacts actuate a battery in a circuit with a tone signal and a flashing light. For car keys, a retainer to make the signals inoperative can be attached to a chain sewn to the clothing of the user.

Title: Tool rolling tubes into tube plates - ensures delay in decoupling after roller begins running in opposite direction
Inventor: HAUSCHKE MANFRED
IPC: B21D39/10
Filed: 1975-04-19
Abstract: The step by step roller is used for connecting tubes to deep tube plates. A rolling mandrel is pressed between the rolling rolls which contact the tube inside walls. Individual rolling steps are adjusted by coupling a stop to the groove in a rolling element. The driving machine coupled to the mandrel is actuated by a controlling system, after reaching the adjusted expansion, for a selected period of time to rotate in the opposite direction. After the rollers begin the run in the opposite direction the coupling of the stop is opened after a given period. The duration of the coupling opening can be adjusted. However, it does not exceed the moment of the termination of the opposite running of the rollers.

Title: Distributor for six-cylinder engine - has rotor arm and suppressor ring with extra blade to prevent explosion during suction stroke
Inventor: HARTIG FRITZ DIPL ING
IPC: F02P7/02
Filed: 1975-05-22
Abstract: The combustion engine distributor, e.g. for an opposed cylinder type six-cylinder engine, has an arm (2) rotated by a shaft (1) carried on an end plate (3) with a C-shaped metal ring (12) around its edge. When the arm (2) is opposite one of the contacts (e.g. 5) so as to connect it to the ignition coil, the other five contacts are earthed by the C shaped ring. In an alternative design, an additional blade extends inwards from a similar C shaped element which causes an ignition for each sparking plug during its suction stroke. This prevents an unwanted explosion inside the ignition chamber.

Title: Thrust bearing for large hydraulic turbine - has thrust pads mounted on elastomeric supports to allow self alignment
Inventor: KOHLER KARL
IPC: F03B11/06
Filed: 1976-06-14
Abstract: The shaft (7) of a large hydraulic turbine is provided with a collar (8) to carry the bearing thrust ring (9), supported by the bearing pads (10) which run on the stationary ring (11), fixed to the structure (13).

Title: Magnetic tape tension control - uses scanner for tension between pulling and pulled tape spools and control variable for adjusting braking or pulling action
Inventor: PLENER HELMUT
IPC: G11B15/48
Filed: 1976-08-18
Abstract: When the tape transport, stops the control variable of the tape tension for the stopping period is stored in a memory, so that it is immediately available when the tape transport starts again. Or, when the tape transport resumes, the drive motor on the winding-on side is supplied with a brief run-up current pulse and the drive motor on the winding-off side is supplied with an adjustable braking current pulse smaller than the run-up current pulse. The tape tension desired for tape tension control results from the difference between the torques supplied by the two drive motors. In one embodiment, the light source is associated with a phototransistor and the output is connected through a memory element to the non-inverting input of an operational amplifier.
Patent DE-2637413-A1 (DE)
Title: Inductive angular velocity transducer - monitors eddy current in rotating element, induced by HF inductive head current
Inventor: HILGNER REINHARD ING GRAD
IPC: G01D5/20
Filed: 1976-08-19
Abstract: The inductively operated angular velocity transducer depends on eddy currents in the metallic element being monitored to produce an impednace change in an inductive measurement head carrying a high frequency current signal. The transducer operates well in hostile chemical, radiation, heat or pressure conditions. The measurement and excitation head (2) consists basically of a coil (3) wound core (4) mounted in a tubular chassis (6) at the end of suitable moutning tube (11). The core and coil are held in position by a spring (9) mounted pedestal (5) so that a field is generated by a roughly 1 MHz excitation current through a non magnetic face plate (7) to induce eddy currents in the object being monitored (2). The velocity of this past the face plate (7) affects the impedance of the excitation coil (3) and this provides the output required.
Patent DE-2643939-A1 (DE)
Inventor: BASTAR BOZO
IPC: H04J1/04
Filed: 1976-09-29
Abstract: In this method, the frequency bands of 162 to 264 kHz and 36 to 138 kHz are generated from the base frequency band of 6 to 108 kHz, according to the CCITT recommendation. The carrier frequencies of 270 kHz and 300 kHz, which are required for frequency conversion on the principle of single-sideband modulation, are generated from the 60 kHz pilot frequency of the 24-channel multiplex part. This makes possible good carrier generation, for which frequency stability is relatively uncritical. The device has two modulators (B1, B3), a demodulator (B2), a carrier frequency generation circuit with a frequency divider (C), a frequency multiplier (D) and two selective amplifiers (E1, E2), and is connected between the multiplex part (A) and the line part (F). <IMAGE>
