Patent DE-2724006-A1 (DE)
Title: Flanged valve body sand casting - produced with core widened to flange diameter to save flange machining
Inventor: WURZER LOTHAR DR
IPC: B22C9/02
Filed: 1977-05-27
Abstract: A sand casting method for a valve body with flanges at both ends has been modified in such a way that the flanged faces need not be machined afterwards and that no machining allowance need be made. This has been achieved by replacing the conventional core which has a dia. to suit the inflow and outflow bores, by one which is widened to the full dia. of the flanges. The flange face is thus bounded, not by the moulding sand, but by the core with its much better surface finish.

Title: Self priming inlet for rotary pump - has air connection from pump inlet to top of inverted U=section of suction pipe to prevent reverse siphonage
Inventor: GROS HERMANN DIPL ING
IPC: F04D9/00
Filed: 1977-07-02
Abstract: A rotary pump (11) draws liquid from a vessel (16), the suction pipe (13) dipping into the liquid and rising to an inverted U (14) above the pump. From this it drops to a U (15) bellow the pump and then enters the pump inlet. Liquid is always trapped between the upper U and the pump to make the pump self priming. A small diameter pipe (18) is taken from the suction inlet of the pump to the top of the upper U. When the pump stops air entering the pump from the discharge side (17) flows through this connection to the top of the U and breaks the liquid column at its highest point. This prevents liquid being siphoned back to the vessel.

Title: Async. machine control system - corrects stator voltage deviations by changing rotor slip frequency, by varying stator current frequency
Inventor: WOLF HORST DIPL ING
Filed: 1978-06-19
Abstract: The machine speed is controlled by varying the stator current. When the speed is controlled, the asynchronous machine terminal voltage is continuously kept at an approx. constant value. When the stator voltage deviates, it is corrected by changing the rotor slip frequency by changing the stator current frequency faster than the stator current magnitude can change. The stator current frequency change is so small, that the rotor slip frequency remains smaller than the frequency difference between the pull-out point and synchronism point of the torque-rotor frequency characteristic.

Title: Headlight dipping system for motor vehicle - uses radio receiver to detect oncoming vehicle and to initiate dipping automatically
Inventor: THIELER WOLFGANG ING GRAD
IPC: B60Q1/14
Filed: 1979-05-22
Abstract: The headlight dipping system has a radio transmitter and radio receiver fitted to the vehicle, e.g. on its roof. The receiver is directional and points forwards whilst the transmitter is omnidirectional. The transmitter's power is chosen so that its range is greater than the range of light from the vehicle's headlights when not dipped. An oncoming vehicle is detected by the receiver detecting that vehicle's transmitted radio signals before the driver is dazzled by the headlights. The receiver controls the dipping of the headlights. All headlights are therefore dipped before either driver can be dazzled by the other's headlights.

Title: Power consumption control system for digital processor - has clock pulse generator disabled at pre-determined period after last key-in operation using counter circuit detector
Inventor: HOSHII TOSHIFUMI
IPC: G06F1/32
Filed: 1979-12-19
Abstract: The power consumption control system for electronic digital data processing devices is provided with a counter circuit (31) to update a time count operation and to count a given time every time any one of the keys in the key input section (3) is depressed. When none of the keys in the key input section (3) is depressed until the counter circuit (31) finishes the count of the given time, the oscillating operation of the oscillator circuit (1) now supplying the clock pulse to the data processing device (21) is stopped. With such a construction, when no keying in operation is performed for a given time while the power source is turned on, the oscillation of the oscillating circuit is stopped to stop all the circuit operations. However, the operation results in the memory are held as they stand. Therefore, wasteful power consumption when an operator fails to turn off the power source switch may be prevented. Additionally, the data obtained before the oscillation stops is held and therefore the data is held even in the course of the operation execution. Accordingly, there is no need to re-enter the identical data at recommencement of the operation.
