Title: Power semiconductor device with tungsten electrodes - has semi-conductor disc chip with PN-junction(s) reaching to its edge
Inventor: BATZIES PETER DIPL PHYS
IPC: H01L23/31
Filed: 1973-12-19

Title: Suction-cleaner for hop-harvesting machines - separates umbels from bines and has wind duct from fan
Inventor: DAUM HERMANN
IPC: A01D46/02
Filed: 1973-12-22
Abstract: The picked crop is transported on a conveyor belt to a suction cleaner enclosed in a housing. The cleaner consists of a duct on the air-inlet side of which is a sloping mesh belt, and on the air-outlet side a fan. The mesh-belt runs over rollers, the outside one being the feed cylinder, and the other one the return cylinder. A gap between the conveyor belt and the mesh belt is for the crop to fall into. The crop particles fall onto the outer cylinder of the mesh belt, which runs in a direction contrary to their direction of falling. The umbels and short stalks fall down along the lower half of the mesh belt onto another conveyor belt, whereas the leaves and longer stalks remain on the outer cylinder of the mesh belt as a result of their predominantly flat shape, and the suction exerted on them, until they are conveyed to the top of the guide roller.

Title: Double-acting piston IC engine - has two series cylinders having interconnected pistons and common combustion chambers
IPC: F02B75/28
Filed: 1974-01-09
Abstract: The ic engine has two piston chambers in series with interconnected pistons for synchronous reciprocating motion the combustion-expansion cycle of one cylinder serving to return the other piston to the fuel-compression state. Return-movement of the piston bringing about compression of gases forces a ball valve out toward the distant end of the ignition cylinder away from the approaching piston, to seal the far end of the ignition chamber, whereby as the approaching piston continues to approach and finally to become flush with the piston chamber, gases within the space adjacent the approaching piston are compressed within the ignition chamber prior to ignition by a spark plug within the ignition chamber. The chamber is formed within a central division and is common to both cylinders. The reciprocating motion may be used to drive a rotary air compressor.

Title: Lining protection for arc furnace used in steel mfg. - comprises measuring its electric resistance during melting down of solid charge
Inventor: POKLEKOWSKI GUENTHER DR ING
IPC: H05B7/00
Filed: 1974-01-30
Abstract: During the melting of a solid charge, the electric resistance is measured between at least two points on the furnace lining above the melt and, when a sudden, persistent drop in resistance occurs, the power is reduced to the value employed after melting down. The A.C. resistance is pref. measured, esp. via the impedance w.r.t. magnitude and phase, taking the dialectric properties of the lining into account. The pref. device uses two electrodes in contact with the lining, fed by an A.C. generator with adjustable frequency, the circuit contg. a band-pass filter, A.C. voltmeter and a controller which adjusts the power supply to the arc. Method prevents the lining from being directly exposed to the higher arc temp. used for melting down, esp. in large arc furnaces with high power ratings, and increases the lining life.

Title: Remote control of typewriter for use by disabled - involves counters for selection of character from matrix
Inventor: LENZEN JUERGEN
IPC: B41J7/00
Filed: 1974-02-09
Abstract: The matrix is operated from a four station control such as a joy stick whereby two reversible counters are actuable up or down and across the stations of a square matrix. Each station is formed by an AND gate whose output becomes "1" if the respective inputs are both made "1" by coincidence of a given two counts of the counters. The output of the AND gate energizes a visual indicator of the character selected in this way. Further, the output of the AND gate is connected to effect printing of the corresponding character by the typewriter on activation of a switch.

Title: Variable geometry car seat - with periodic variation to prevent stiffness and backache on long journeys
Inventor: BECK ARMIN DR
IPC: B60N2/90
Filed: 1974-08-30
Abstract: The car seat is fitted with an array of hollow pockets inside the padding, with the pockets connected to a control manifold and to a pressure supply.
