Patent DE-2446685-A1 (DE)
Title: Rapid emptying device utilising water pressure - for filling eg. sand filter pits
Inventor: REPPERT HERBERT
IPC: B01J4/00
Filed: 1974-09-30
Abstract: In an apparatus for the automatic emptying of containers without the supply of energy, in which after a desired maximum water level has been reached, sufficient upthrust is produced by a float coupled with the closure, that this raises the water pressure acting on the closure in the discharge opening and in such a way as to effect the lifting away of the closure and discharge of the water. After lifting off the closure, water enters an air chamber between this and a smaller auxiliary closure sitting underneath in the discharge. Water fills the chamber, the water pressure load on the closure is increased and the upthrust released on the float overcomes the smaller water pressure on the auxiliary closure resulting during filling of the air chamber and the suction resulting in the inserting water discharge. The floating of both coupled closures and the free discharge of the water from the container proceeds for such time until the main closure sinking with the falling water level is pressed onto the discharge opening and the auxiliary closure also floats down into the closure position with the remaining underground water.

Title: Boiling plate with three heating resistors - is controlled by seven position switch and temperature limiter on boiling plate
Inventor: FISCHER KARL
IPC: H05B3/68
Filed: 1974-12-17
Abstract: The limiter switch is used to turn off a part of the heating apparatus and the limiter has at its fixed limiting temperature a narrow temperature differential between switching on and off, and is thermally tightly coupled with the boiling plate (11) heater temperature; the power of the disconnected heaters (N2, N3) is more than half of total power (N1, N2, N3). The result is that rapid heating takes place up to the chosen temperature, at which point most of the heating is discontinued and the heater (N1) provides sufficient heat to maintain a steady temperature. A hand knob is provided for switching the apparatus on and off.

Title: Protection circuit for series connected thyristors - has signal generator for each thyristor and signal transmitter to evaluator
Inventor: LEOWALD KARL-FRIEDRICH DIPL IN
IPC: H03K17/10
Filed: 1975-04-30
Abstract: The circuit is intended to prevent self-igniting of the thyristors and contains for each thyristor potential, which generates a switching signal when the current at the thyristor reaches zero, or the voltage drops below a preset negative value. Each such device has a series connected transmission device for the switching signal to an earthed evaluator, which generates a time signal for a monitoring time interval, transmitted via a second transfer device to a monitoring circuit at the thyristor potential. A second signal generating device provides a second signal at a preset positive voltage, transmitted to the monitoring circuit. The latter controls the igniting circuit on appearance of the second switching signal during the monitoring time interval.

Title: Rotation speed measurement using integrating gyroscope and torque coil - current is applied to achieve defined angle then reversed for equal but opposite torque
Inventor: ROELKER ALBERT ING GRAD
IPC: G01C19/42
Filed: 1975-10-04
Abstract: The measurement of rate of revolution is carried out by using an integrating gyroscope. A constant external turning movement is applied to the gyroscope by means of a torque coil mounted on it until a defined angle is achieved. The current to the coil is then reversed to produce an equal and opposite torque until the same deflection is achieved in the opposite sense. The rotation speed is determined in a processor from measurement of the deflection angle and the times to the first and second torque switching as well as a time-averaged value for the first switching time.
