Title: Fire protective door for thin movable partition wall - has cooling filling in reinforcing frame and foaming filling in cavities
IPC: E06B5/16
Filed: 1976-03-24
Abstract: The fire-screening door or flap is of the type installed in a wall opening or movable partition wall, with a stiffening frame of shaped steel bars covered outside with insulating strips. The stiffening frames (6) for the case and/or door leaves (2, 3) are sheathed and/or filled with a material (9) which cools them under the effect of heat, pref. one with an evaporating fluid. The sealings (16) in the rebates (11, 12) are in the form of cavity units of durable elastic material, the cavities being filled with material which foams under the effect of heat. A sealing strip of fireproof material may be inserted between the case fixture section and the masonry. Case and leaves may be built flush into a partition wall. This affords a high degree of fire protection and sound insulation, with rebates providing prolonged sealing from gas and smoke, and it can be built as a unit into thin partition walls.

Title: Electromagnetic fault recorder analogue for inputs and binaries - has discs recording amplitudes of periodically compared input signals and states of contacts
Inventor: SCHLEBAUM KAREL HENDRICK
IPC: G01R17/04
Filed: 1976-06-02
Abstract: The electromagnetic fault recorder analogue for input currents, input voltages and binary criteria, such as conditions of contacts, consists of a constant velocity infinite tape with recording discs placed at regular intervals. The discs record amplitude of periodically compared input signals from the zero point and states of contacts at right angles to the motion of a recording paper travelling in a fixed relation to the motion of the tape. There is a printing unit extending over the recording range, controlled by comparators which compare the input voltages. The comparison is via pulse circuits with step shaped reference voltages produced from coupled reference voltage generators. This is achieved by setting the positioning pulse read off from the tape by a positioning pulse generator or a coding disc rigidly coupled to the tape.

Title: Automatic centering of conductor in insulating covering - uses mean value of video signal generated on camera tube target with readjustment of radiation sources if necessary
Inventor: DOMORAZEK GOTTFRIED DIPL ING D
IPC: B29C48/06
Filed: 1976-09-24
Abstract: Conductor position inside the covering is image by penetrating radiation on a camera tube target, and the image is scanned by an electron beam. Its deviation from the central position causes an asymmetry of the video signal from which an evaluation device derives control pulses used for centring the conductor in the covering. A mean value of video signal amplitudes is formed, and when it deviates from a nominal value, intensity of radiation sources is so readjusted, that the mean value returns to the nominal value.

Title: Automatic fuel consumption measurement for IC engine - involves calibration liq. filling calibration glass with two probes controlling valves
Inventor: MEYER WILFRIED
IPC: G01F9/00
Filed: 1977-08-10
Abstract: The device can be used for measurement of fuel consumption of heaters etc. IT comprises two vessels separated by two highly flexible, fuel resistant diaphragms. One vessel represents the gauge glass, while the other holds between two probes a weight calibrated reference liquid. The device is connected to an electronic control unit and through a pipe (03) to the engine etc., controlled by a solenoid valve. The gauge glass (05) is automatically filled through electronically controlled valves (02, 06) and a bent pipe (04) reaching to the diaphragm (08).
