Patent DE-2921565-A1 (DE)
Title: Sterile mixing of powder with liquid - using ampoule of liquid the end of which is sheared by pulling up plunger which pushes over collar to break end of ampoule to cement
Inventor: GALIA KARL
IPC: A61J1/20
Filed: 1979-05-28
Abstract: Powder is held in a flexible bag clamped into circular housing above which is a plunger contg. sealed ampoule of the liquid for mixing into the powder. The whole package is sterile. The housing is in the form of a holder to allow the ampoule to be opened. The ampoule has a teat which extends below it. This is held in a collar, one side of which is wedge shaped. The ampoule plus collar, are mounted inside the plunger. The plunger has a horizontal rib inside when the plunger is pulled up this rib rides up the wedge on the collar, pushing the collar to one side. This shears off the teat and allows the liquid in the ampoule to fall onto the powder in the flexible bag. Used for mixing bone cement method. Allows the cement to be made with min number of hand actions.

Title: Bipolar electrolytic capacitor - has two or more transversely-formed electrode foils with absorbent spacers
Inventor: OEHME FRANK DIPL PHYS
IPC: H01G9/04
Filed: 1979-06-23
Abstract: The formed electrode foils are arranged transversely to one another and separated from the unformed electrode foils by several layers of absorbent spacers. After being wound together and impregnated, both formed electrode foils are completely covered and integrated into a series of formed-unformed-formed electrode foil. The unformed electrode foils are not connected electrically and are therefore free in the potential gradient to fluctuate electrically, and on an A.C. voltage, to adjust to a low positive potential less than ten volts with reference to the respective negative formed electrode foil, e.g. one to four volts.

Patent DE-2933716-A1 (DE)
Inventor: RAFAEL ARUTH
IPC: C10J3/48
Filed: 1979-08-21
Abstract: An arrangement for pressure gasification of fine-grain coal in which the exit of a reactor is followed by a waste heat boiler for cooling the generated gas. The waste heat boiler has a radiation section and downstream heat exchanger surfaces. The reactor is provided, furthermore, with cooling cubes which are studded and lined with refractory ramming mix. The radiant type heating surfaces are sized so that the gas temperature at the exit of the radiation section is situated below the ash sintering temperature of the coal being used. On gas sides, the radiation section is followed by a pressure vessel accommodating convection type heating surface banks which are swept by the generated gas. The radiation section may be in the form of two gas passages through which the gas flows successively. These gas passages are formed by the tube walls welded between each other in a gas-type manner.

Patent DE-2944796-A1 (DE)
Inventor: GOEDECKE LUDGER DIPL ING
IPC: G05B9/02
Filed: 1979-11-06
Abstract: A heating arrangement in a fixing station of a printing device has its operation monitored by an arrangement in which a measuring element is disposed in series with the heating element and a switch element. The measuring element is traversed by the heating current and emits a corresponding voltage which is supplied to an amplifier circuit which produces pulse-shaped clock signals as long as the heating current flows through the measuring element and the heating element. The clock signals are supplied to a reset input of a flip-flop whose dynamic input is connected to an oscillator operating at a frequency lower than that of the alternating current so that as long as clock pulses occur, the flip-flop is constantly reset. Therefore, the flip-flop can only be set over a longer interval when no heating current is flowing. If heating current flows although no heating current should flow, the same is identified by a counter whose counting input is connected to the amplifier circuit and whose reset input is connected to a heat sensor. Therefore, an undesired heating current through the heating element causes operation of the counter. A set flip-flop or a counting counter indicate malfunctions of the heating arrangement.

Title: Warning device for reversing vehicle - uses horn shaped transmitter receiver mounted on rear of vehicle to give visual or audio indication
Inventor: FILIPOV MLADEN
IPC: G01S13/931
Filed: 1980-03-07
Abstract: The warning device mounted on the vehicle has a horn shaped emitter (11) mounted at the rear of the vehicle being fed from a high frequency oscillator (12), using a frequency of 4 GHZ. This oscillator (12), is activated via a switch (13) connected to the gear base or gear lever of the vehicle and is automatically switched on when the vehicle reverses. The horn-emitter (11) forms a transmitter-receiver, which emits electro magnetic waves with the frequency of the oscillator (12). If these waves are reflected by another vehicle or obstruction (14) at the rear, they are fed to a demodulator (15), where the difference frequency between transmitted and received waves is fed to an amplifier (16), then to a threshold value circuit (17) which produces an output signal. This signal activates a relay (19) via a monostable circuit (18) having a hold time of 10 seconds, after which the relay (19) drops out. The relay is used to indicate optically, or acoustically, that the vehicle is reversing into another vehicle, wall or other obstruction.

Title: Frame-saw type feed wood aligning and clamping assembly - has guided holder carriages circulating to and from machine front
Inventor: RIGHI EDUARD
IPC: B27B29/04
Filed: 1980-08-25
Abstract: The appts. is for setting up and firmly holding pieces of timber conveyed in succession to a woodworking machine, such as framesaw. One or more carriages or other devices (1), for setting up and holding, move in a circulating direction in front of the machine, conveying pieces of timber to it singly or together. The movement can involve a rail guideway (2) permitting an individual carriage, with wood clamped at its end, to traVel to a position directly in front of the machine; after unclamping it is thrust (3) sideways, upwards or downwards to the return rails (4), conveyed to the rear and then thrust (5) against into the feed rails. This ensures that trunks are held firmly in position until the frame saw is reached.

Patent DE-3035171-A1 (DE)
Title: Melting furnace electrode feed control - using sensor for field changes due to electrode advance
IPC: H05B7/109
Filed: 1980-09-18
Abstract: A control system for the feed of an electrode of an electric melting furnace, to keep the impedance between electrode and melt constant, includes an ultrasonic transducer which produces ultrasonic vibrations in a magnetostrictive wire along a bore with a magnet in a piston. The piston moves with the electrode holder and this alters the ultrasonic field. The transducer picks up this change and corrects the electrode feed circuit accordingly. The impedance control now responds with a much reduced delay to changes and with a much greater accuracy.
