Patent DE-2458917-A1 (DE)
Title: Controller for light beam focussing - has photo-detector reader element with peak signal valve augmented by pilot signal
Inventor: TINET CLAUDE
IPC: G11B7/09
Filed: 1974-12-12
Abstract: In one embodiment of the invention the incoming light beam (1) impinges on an objective lens (2) mounted in a carrier (21). The parallel beam is brought to a focus (22) on the surface (41) of the data carrier (4) to a photodetector (3), followed by an amplifier (5). The signal from the latter returns through a curve envelope detector (8) to a peak value detector (9) which operates a switch (91). A sinusoidal pilot signal is injected from an external generator, and this is fed through a filter unit (10) which enables the pilot signal to pass through. Other components include a d.c. power source, adder, motor and phase shifter (20).

Title: Oil level dip:stick for engines - has flexible sleeve with corrugated side walls for cleaning dip:stick before reading is taken
Inventor: RUEBSAMEN WILLI
IPC: G01F23/04
Filed: 1975-10-22
Abstract: The dip-stock for measuring oil level in car engines can be wiped free of oil without the use of rags.

Title: Rail conversion for tractor - with flanged wheels moved by rear and front hitches to sit between pneumatic wheels and rails in friction contact
Inventor: BUETTNER SIEGFRIED
IPC: B60F1/00
Filed: 1975-12-04
Abstract: The front and rear hitches of the tractor are fitted with rail wheel sets (2, 19) which are lowered onto rails and are then pressed down to lift the tractor off the ground and support the weight on the rail wheels. Drive is by swinging one set of rail wheels into contact with the drive wheels of the tractor. The system provides a simple and economic rail conversion for a road tractor. No special fittings are required if the tractor has front and rear hitches. No special drive is required for the rail wheels, just a friction contact drive with the existing drive wheels.

Title: Quarrying nonmetallic minerals esp. coal - using thermoplastic gas and dust suction pipes broken up during quarrying
Inventor: PUTTER WARNER JAN DE
IPC: E21B17/08
Filed: 1975-12-13
Abstract: Process involves drilling longitudinal boreholes and introducing gas suction conduits forming a gas suction system to remove gases and dust particles, following which minerals are quarried from deposits. Novelty consists in using non-metallic gas suction conduits, which are left in boreholes during quarrying and are progressively broken up during separation of the minerals. Conduits pref. consist of plastic, of strength such that the conduits can be broken up with quarrying machinery during separation of minerals. Use of non-metallic conduits allows taking of electromagnetic measurements; minimises damage to quarrying tools and obviates removal of gas suction conduits during quarrying. In using plastic, costs are reduced and no. of joints can be limited.

Title: IC engine running on weak air fuel mixture - has sparkplug electrodes arranged at antechamber connecting channel
Inventor: KATO TAKASHI
IPC: F02B19/12
Filed: 1975-12-30
Abstract: Engine has an ante chamber in the cylinder head. The connecting passage between the ante chamber and the main combustion chamber contains the spark plug electrodes. The passage diameter (10) is greater where the spark plug electrodes enter than the passage diameter junction with the main combustion chamber. Ignition of a weaker than normal mixture is improved because the exhaust gases which remain after each power stroke are pushed back into the antechamber away from the spark plug electrodes on the compression stroke.

Title: Dot printing head pivoted clear of paper - has print receptor and friction pawl acting on stationary track
Inventor: KOCH KLAUS-PETER ING GRAD
IPC: B41J19/94
Filed: 1976-02-07
Abstract: Dot printer has a head movable linearly in the direction of the print line and movable pivotally about an axis parallel to the print line. During printing the head is pivoted into a position close to the print receptor. During the return of the head to the beginning of a new line the head is pivoted clear of the receptor. The latter pivoting is effected by a one-way detent comprising a friction pawl pivoted to the head and biased against a stationary track. During the return of the head the pawl is tilted and applies a force on its pivot bearing which pivots the head.

Title: Relative motionless condition detection - using at least one position pick up and monitoring unit for two machine parts rotatable w.r.t. each other
Inventor: TOMIC SLOBODAN
IPC: G01P13/00
Filed: 1976-03-31
Abstract: In a practical application the rotational condition of an axle (1) can be tested. An angle coder (2) is installed as a position detector. This can be in the form of a BCD code coding disc and a corresponding number of photocells. The output comprises eight digital channels (3) corresponding to an eight bit code. These channels (3) lead to an evaluating unit (4) with an output signal lead (5). The control lead (6) is connected to a switch (8), e.g. press-button, via a timing unit (7). The switch (8) brakes the axle (1) which is typically the drive shaft for the machine concerned. Simultaneously, a control signal is delivered to the timing unit (7). This unit, in turn, delivers this signal as a delayed output signal. This signal is conducted to the evaluating unit (4) as a monitor start signal by means of lead (6).
Patent DE-2613896-A1 (DE)
Inventor: KIENBERGER HELMUT DIPL ING
IPC: H02H7/12
Filed: 1976-03-31
Abstract: In such converters, the influence of the tilt of the transistor current pulses on the duration of the current pulses is to be largely limited. For this purpose, the converter is constructed in such a manner that the limiting of the instantaneous current value is carried out by comparing a measurement voltage (Usoll-Uist) derived from the transistor current pulses (i1) with a periodic sawtooth voltage (USZ) of constant edge slope. The converter is particularly suitable for current supply devices in which a number of DC converters operate in parallel without current balancing control. <IMAGE>

Title: Synchronising and stabilising circuit for DC regulation in TV - with switching circuit to provide stabilised output insensitive to disturbance effects
Inventor: HOLLANDER WILLEM DEN
IPC: H02M3/335
Filed: 1976-06-10
Abstract: A synchronising and stabilising supply circuit operates on an A.C. voltage supply in conjunction with a regulator to generate a D.C. voltage, the amplitude of which is proportional to the ratio of the period of two drive signals. The circuit is for application in television receivers and minimises the effects of disturbances. The un-isolated stage of the receiver is coupled to an A.C. supply over a diode and capacitor and supplies the winding of a transformer. The transformer, transistor and diode coupled to the secondary winding operates as a regulator controlled by drive signals from a generator formed from a multi- vibrator and associated stages. Outputs of the circuit are coupled to an isolated stage to generate the d.c. output.

IPC: A45D1/04
Filed: 1976-09-14
Abstract: The curling iron has a tubular barrel (10) in which a heater is axially slidable between advanced and retracted positions. A handle (11) is located at one end of the barrel and a liquid-contg. reservoir (12) is located at the other end.
