Title: Overload protection for supply transformer for electronic equipment - uses non-inductive additional winding on transformer as temp. sensor
Inventor: STERNAD ROLF
IPC: H02H5/04
Filed: 1980-06-25
Abstract: The application is typically to the power supply transformers for audio amplifiers. An additional winding (5), of fine wire gauge, is mounted on the transformer, typically between the prim. and the sec. The coil (5) is bifilar wound (6,7) and is thus free from an induced a.c. voltage. The coil (5) is connected as the variable element in a dc bridge (1,2,6,7;3,4) whose diagonal is the input to a comparator (9). The comparator (9) is pref. an operational amplifier whose output controls switching transistor (15) in series with the operating coil (23) of a relay (16). If the dc bridge is unbalanced by a large increase in coil resistance, due to high temperature in the transformer, the amplifier output changes polarity. The transistor switches off and the relay contacts open to switch off the power supply to the transformer. The latter is then automatically reconnected when the winding have cooled to the point where the comparator again changes its output polarity.

Title: Moving object detection, identification and speed measurement - by correlation of signals corresp. to ambient reflected light and stored reference value
Inventor: KRISZIO HORST
IPC: G01S11/12
Filed: 1980-08-09
Abstract: A method of detecting and identifying moving objects and for determining their speeds involves the evaluation of beams reflected from the objects. It enables reliable identification and speed measurement after a coarse alignment of the system perpendicular to the direction of motion of the object. The method involves extracting a signal from the ambient light reflected by the object. The signal is characteristic of the object and is compared with sorted object patterns. Signals may be extracted at different times and from different points and then correlated with each other. The signals can be passed to a different position for processing and display and for camera or warning activation. The signals are obtained using a passive optical sensor connected to a signal processor contg. a correlator, peak detector and amplifiers.

Title: Control for a hydraulic displacement motor with variable displacement
Inventor: JACOBS HARVEY C
IPC: F15B11/02
Filed: 1981-03-18
Abstract: An energy-saving control for at least one displacement motor of a plurality of motors which are driven by a pump, controlled in a pressure-compensated manner, by way of a branch. The controlled motor is connected on the high pressure side to the branch and on the low pressure side to an accumulator and drives a small positive displacement pump, preferably an existing feed pump, and produces a flow through a square edge orifice in an isolated control circuit. Responding to load changes, a hydraulic booster monitors the pressure in the control circuit and adjusts the engine stroke, preferably by adjusting the angle of a tiltable plate producing the piston stroke. When the pressure in the control circuit falls due to an increasing load, the stroke is increased, being reduced when the control pressure increases as the load decreases. In each case the small positive displacement pump returns the pressure in its isolated circuit essentially to the initial pressure as soon as the engine stroke has attained its new adjustment.

Title: Bridge rectifier circuit
Inventor: WAGNER BURKHARD
IPC: H02M7/162
Filed: 1981-07-18
Abstract: The invention relates to a bridge rectifier circuit for obtaining DC voltages. The aim of the invention is to create a rectifier circuit which is accident proof and requires a lower economic outlay than the bridge rectifier circuit. The object of the invention is to design the rectifier circuit such that fewer diodes are required than in the case of the bridge rectifier circuit. According to the invention, the technical object is achieved in that a thyristor is in each case arranged downstream of the fuses, in that the outputs of the thyristors are connected to one another and their control electrodes are connected via resistors and diodes arranged downstream of them to the respectively opposite output of the transformer, and the inputs of the thyristors are connected via in each case one capacitor and the resistors allocated to them to their own control electrodes. The solution according to the invention is used in those fields in which accident-proof rectification is required and the use of the bridge rectifier circuit is economically more costly.
