Title: Wind turbine is posited with rudder to maintain direction into wind - and bevel gear transmits shaft motion to pulley wheel
Inventor: MALZAHN EUGEN
IPC: F03D3/04
Filed: 1974-02-07
Abstract: A wind tubine with a vertical shaft is freely mounted on a turntable that is supported on ball bearings which are located in a base plate. The turbine has a rudder to steer the inlet opening into the wind direction. A number of profiled blades are rigidly fixed to the turbine shaft and air flow passing across the blades causes rotation. A bracing strap supports the housing and is located in a central bearing. A bevel gear transmits the output of the turbine to a friction pulley mounted on a horizontal shaft output supported in bearings.

Title: Retractable brake for loose ski - is released by separation of boot from ski
Inventor: SITTMANN GEB VOESTER BRIGITTE
IPC: A63C7/10
Filed: 1974-02-08
Abstract: To brake a loose ski from escaping downhill, a retractable brake arrangement is fixed to it. The brake element is held in its inactive position by a spring loaded retainer. The retainer is linked to the safety fixture or ski boot. When the fixtures opens, the retainer is dislocated which in turn activates the brake. The force required to release the brake retainer can be adjusted by varying the spring pressure on it. Preferably a second linkage is also incorporated into the system with an additional coupling, and which when the skier falls, initially frees the release element of the brake.

Title: Synchronising loop system for groups of synchronous motors - has each motor controlling next motor converter to form closed loop
Inventor: LOSENKO WALERIJ K
IPC: H02P5/56
Filed: 1974-02-28
Abstract: The synchronising system, for groups of synchronous motors, has each motor (2) controlled by its own converter (5) and coupled to a control circuit (4) which controls the settings of the converter belonging to the next synchronous motor. All the motors are thus connected into a closed loop and all can be regulated by regulating just one of them. The system is cheaper and less complicated than synchronising systems which involve using main motors with balancing asynchronous machines.

Title: Earth drill for geothermal bores - tip driven down by cable kelly bar travelling in tool shaft tube
Inventor: HENSBERG FRIEDRICH
IPC: E21B11/02
Filed: 1974-06-05
Abstract: Earth drill, typically for geothermal recovery, consists of a tool with tubular shaft and reinforced tip. The shaft is of strong material and encloses a kelly bar which falls onto the tip, also made of strong and hard material, and thus drives the tip into the ground. The kelly is hauled back up by a cable and then allowed to drop back to repeat the blow. To ensure smooth and unimpeded travel within the shaft tube, the kelly rod is sealed against water and air with respect to the bore. The cable is made of spring steel and is designed as a smooth rod where it passes into the encapsulated kelly bar through a pressure proof gland seal.

Title: Upright for guide rails and crash barriers - has I-section with unequal flange widths to improve bearing capacity
Inventor: MICHNA RUDOLF ING
IPC: E01F15/04
Filed: 1974-11-28
Abstract: The upright is made of an I-shaped section with one flange wider than the other. This uses a minimum of metal but gives maximum resistance to sliding into the ground because of the wide flange. To avoid the section being bent while being driven into the ground, the ends of both flanges are reinforced, by inwardly extending lips. The connection zone between the web and the upper larger zone tapers inwardly from the flange to the web.

Title: Fast response brake valve - with pre-stressed spring for immediate opening when pedal operated
Inventor: VOLLMER OTTO
IPC: B60T15/04
Filed: 1975-02-18
Abstract: The brake control valve is operated from the brake pedal and closes the brake venting line while at the same time opening the brake inlet to the brake pressure supply. In order to achieve a good brake control for a minimum of pedal travel, without increasing the valve throughput cross section, the valve element is linked to the pedal by a special spring which is pre-stressed by an amount sufficient to overcome friction etc, so that the brake operates as soon as the pedal is pressed. The system minimises the hysteresis of the pedal operation.

Title: Control cct. for AC motor - returns control gradually back to normal after failed supply returns
Inventor: MATSUDA YASUO
IPC: H02P21/22
Filed: 1975-05-06
Abstract: The control circuit, for an a.c. motor, has a switch that opens when the supply fails. When the supply returns, the voltage regulator gradually returns to its normal state and thereby the voltage on the supply rectifier is only gradually increased. The frequency divider is controlled such that the static inverter has a load free interval after the supply has returned to normal. The switch is then closed after a given delay so that the frequency divider then receives an input. The control circuit monitors the phase of the motor's terminal voltage.

Title: Picture-size stabilising circuit for TV receiver - alters power consumptions of tube and video amplifier in opposite sense to keep sum const.
Inventor: HIRSCHMANN WALTER
IPC: H04N3/223
Filed: 1975-08-04
Abstract: The picture-size stabilising circuit, for a T.V. receiver, prevents changes in picture size due to fluctuations in loading by keeping the sum of the power consumed by one of the video amplifiers and the power consumed by the tube itself constant. When the picture luminance changes, the beam power consumption acts in the opposite direction to the power consumed by the video amplifier. Two circuits may be used to perform this task. The first is for a tube controlled from the cathode and has a regulating pnp transistor inclined in the video amplifier out put stage. An alternative circuit is for a tube controlled from a grid and has a regulating npn transistor in the video amplifier output stage.
