Title: Controlling anode effect during electrolytic mfr. of aluminium - where computer fed with anode voltages operates hoist raising or lowering anodes
IPC: C25C3/20
Filed: 1979-11-03
Abstract: During the prodn. of Al in an electrolysis cell contg. molten cryolite and alumina, the normal voltage is 3.8-4.5 but this can rise to more than 30 V if the melt becomes low in alumina. This voltage increase is known as the anode effect, and wastes energy while also increasing anode consumption. The invention measures the anode voltage, and raises the anodes to create the anode effect, and lowers the anodes to eliminate the effect. When the voltage attains 8 V, the anodes are pref. raised until a max. of 28 V is reached; and the anodes are lowered to obtain te desired operating voltage. The vertical movements of the anodes are pref. controlled by an electronic computer fed with the anode voltages. The anode effect can be created and eliminated at prescribed times to assist completely automatic operation of the electrolysis cell.

Title: Tensioning device for two-for-one spindle - has spring capsule seated on pneumatic piston within cylindrical housing
Inventor: WEHRMEISTER GERHARD
IPC: D01H13/10
Filed: 1980-01-08
Abstract: A yarn tensioning device for a two-for-one spindle comprises a cylindrical housing forming a continuation of the spindle within which a tensioning capsule consisting of two telescoping sections joined by a compression spring restricts the yarn path between two friction braking rings. The upper ring is fixed adjustably to the upper section of the housing, the lower ring being mounted in an air-tight piston which rests on a spring in the lower section of the housing. In the bottom of the housing below the piston is a vertical pin which projects through the lower friction ring when the piston is in its lowered position for threading the spindle, to raise and displace the capsule laterally, leaving an unobstructed passage for the yarn. This construction enables the tension to be adjusted, and enables the spindle to be threaded by any suction-threading device, without the necessity of semi-dismantling the device.

Patent DE-3023833-A1 (DE)
Title: Regenerator for multilevel digital signals - has multiple differential amplifier formed by single multi-emitter transistor and several single-emitter transistors
Inventor: JUNGMEISTER HANS DR ING
IPC: H04L25/49
Filed: 1980-06-25
Abstract: A multi-emitter transistor (T8) receives the input signal (U(t)) at its base and has n emitters, where n is the number of voltage thresholds or levels in the digital input signal. Each emitter is connected to the emitter of a normal transistor (T12-T15). The collectors of the normal transistors are connected via a common resistor (RA) to OV - as is the collector of the multi-emitter transistor. The threshold voltages (U1-U4) are connected to the bases of the normal transistors. The normal transistors and the multi-emitter transistor therefore form a series of differential amplifiers. The output is taken from the collectors of the normal transistors and is applied to the data input of a flip-flop (FF). The regenerated output (A) appears at the flip-flop's output. Control signals (S1,S2) and reference voltages (UR1,UR2) are applied to further transistors (T9-T11, T16-T18) supplying current to the emitters of all the transistors. The advantage lies in reduced supply current and in simplicity. The regenerator can be readily realised as an integrated circuit.

Title: Piezoelectric knock vibration detector for combustion engines - has shunt resistor eliminating sudden depolarisation by removing electrical charge
Inventor: BONITZ JOERG DIPL ING
IPC: H01L41/047
Filed: 1980-07-18
Abstract: The sensor is for detecting the vibrations occurring with knocking in an internal combustion engine contains a flat piezoelectric element (10) with contacts on two sides. The sudden depolarisation of the piezoelectric element conventionally experienced is eliminated and the uniformity of the measurement characteristics over long operating periods ensured. A shunt resistance (17) connected between the two contacts (11,12) removes the charges arising in the capacitive element during operation. The resistance can be in the form of a resistive paper applied to the contacts or of a sealing compound mixed with conducting material. The use of a sealing compound mixture with conducting material results in no change to the construction methods employed with conventional sealed knock detectors. The elimination of strong capacitive charges prevents the associated measurement errors. 1+2.
Patent DE-3031162-A1 (DE)
Title: Ski binding with axially adjustable toe clamp - has sprung-piston heel clamp with pressure detectors and electronic release circuit
Inventor: BILDNER CAROLYN
IPC: A63C9/08
Filed: 1980-08-18
Abstract: The binding consists of two clamps, one at the toe and one at the heel of the ski boot and both mounted on the ski. One clamp is sprung and has pressure detectors measuring the force exerted by the ski boot on this clamp. When the force exerted exceeds a given threshold, an electronic circuit produces an electrical signal that actuates an unlocking mechanism. The unlocking mechanism releases the sprung clamp, allowing the ski boot to come free of its binding, thereby preventing a serious leg injury. The sliding clamp is the one at the toe and is moved by an adjustment screw along the axis of the ski. The heel clamp consists of a telescopic sprung piston whose round tip locates in a recess in the heel of the boot. The heel clamp has an optical display showing the clamping force being exerted on the boot. The pressure detectors are located either on the periphery of the piston or in the wall of its cylindrical hole.

Title: Machine tool, in particular a multi-spindle automatic lathe
Inventor: YOUDEN DAVID H
IPC: G05B19/06
Filed: 1981-02-12
Abstract: The invention relates to a drive system for a multi-spindle automatic lathe, in which a special servomotor is provided for driving the control shaft, which serves as a main control element for the time and spatial sequence of the movements of the tools which machine the workpieces carried by the spindles. According to the invention, the speed of the servomotor is regulated via a feedback loop with a tachometer in such a way that it is kept at a predetermined value. The control shaft rotates either at a high speed in order to move the tools in rapid traverse or at a low speed which corresponds to the feed rate for the tools during the machining of the workpieces. Furthermore, according to the invention a second tachometer driven by the spindle-drive system produces a signal which is proportional to the spindle speed and by means of which the control-shaft speed is adapted to the spindle speed. In this way, the couplings normally present for the change-over to rapid traverse and for a reversal of the direction of rotation of the control shaft can be dispensed with and replaced by switches and potentiometers. <IMAGE>

Title: Cylinder kit especially for engine-power-driven heat pumps
Inventor: DERER ANDREAS
IPC: F02B63/06
Filed: 1981-02-18
Abstract: The invention is a kit, by means of which series production engines can be converted into engine-power-driven compressors, mainly for heat pumps. The conversion is generally effected in that, by means of the kit, one combustion cylinder is converted to function as the compression cylinder, the remaining combustion cylinders serving for the drive. The kit is so designed that no refrigerant vapour can get into the crankshaft space and thence into the combustion cylinders. The advantage of this construction compared to others lies in the fact that the separation of the refrigerant circuit from the combustion cylinders is more reliable and the construction is accessible and inspectable from outside.
