Title: Film drive control for sound cine camera - has claw motor controlled by loop size using switching circuit
Inventor: EBERHARDT PETER DIPL ING DR
IPC: G03B31/02
Filed: 1979-05-18
Abstract: A film drive control for a sound cine camera has monitors on the film loop (FS) between the sound head and the claw motor for the film gate. The whole camera drive is determined by the size of the loop to prevent film damage, in both running and single shot exposures. The monitors operate a switching circuit for the claw motor while the sound head motor is driven by an impulse generator controlled by another switching circuit. The single shot exposures are driven by signal pulses generated by a switching circuit, with the sound head motor operating for set periods.

Title: Central heating system radiator cell - has rear flange preventing heat loss to adjacent wall by radiations
Inventor: COLLE AUGUSTO
IPC: F28D1/02
Filed: 1979-06-26
Abstract: The radiator cell in heating system is connected to other cells to form heating radiators. Efficiency of the radiator is improved by reducing to the maximum the amount of heat radiated to the adjacent wall. On the rear of the cell is a flange (11) which faces the wall against which the radiator is installed. The surface temperature of this flange is appreciably lower than the temperature of the heating fluid. This flange screens the heat radiated from other parts of the cell towards the wall. The screening flange is connected by a ribbed part (10, 12) which does not carry heating fluid to the main radiator cell.

Title: Gas mixing apparatus control - by timing switch and solenoid operated three=way valve, for breathing and medical appts.
Inventor: SCHWANBOM ERIK DR ING
IPC: B01F23/10
Filed: 1979-07-03
Abstract: A gas mixing device for use in breathing and medical appts. is controlled by a three-way valve in one of the two mixing gas supply lines. When a push button is depressed, a time switch is energised and a pilot lamp lights up. A solenoid magnet then turns the three-way valve to admit a third mixing gas to replace the second. After the set time, the appts. reverts to the original setting. It thus operates automatically and eliminates possible individual timing errors.

Title: Ship identification system for water channel - uses thermal barriers broken by passage of ship to provide characteristic modulated radiation pattern
Inventor: LANG HELMUT
IPC: G01V8/20
Filed: 1979-09-07
Abstract: The ship identification system uses a number of facing transmitters and receivers, one above the other, on opposite sides of the water channel to define thermal barriers broken by the passage of the ship through the channel. An evaluation logic is coupled to the receivers to determine the outline of the hull and the superstructure from the times during which the different barriers are interrupted, as in DE2854215. Each receiver receives radiation from several transmitters, periodically interrupted to provide a modulated radiation component characterising the ship. The system allows identification of two ships passing through the channel at the same time.

Inventor: HAEFELI HANS
IPC: B65G45/12
Filed: 1979-10-19
Abstract: Below the belt (6), a basic frame (3) in which a lift frame (10) is supported by means of connecting links (11) and rollers (12) is supported by means of rollers (4) on running surfaces (2) of foundation rails (1). The lift frame (10) can be displaced with respect to the basic frame (3) by means of a toggle bar (16) operable by a hand lever (21), the lift frame (10) being simultaneously raised by the connecting links (11). By means of this oblique movement in the opposite direction to the movement (B) of the belt (6), plates (7, 8) arranged in series in the lift frame (10) are pressed, with elastic deformation, in the direction (B) against the belt surface. The driveless and therefore simple device cleans reliably and has only slight wear of the plates. In addition, clogging of residues on the plates is avoided, since such residues fall into a drawer (26) arranged below the plates (7, 8). <IMAGE>

Title: Hygroscopic granules dissolution - by inclined jets from slotted nozzles intersecting below charging tunnel
Inventor: SCHULER KLAUS
IPC: B01F5/20
Filed: 1980-02-28
Abstract: A device for the dissolution of granular hygroscopic substances in water, esp. of flocculants for use in the sewage clarification, consists of a tank in which two flat jet slotted nozzles direct their fluid jets at an angle towards each other. The two jets intersect each other directly below a funnel through which the granules to be dissolved are charged. This creates an effective wetting and enclosure of each granule of flocculant before the granules can coalesce and form lumps. The result isa reduction of the flocculant consumption.

Title: Defroster control for evaporator of refrigerator or heat pump - utilises increase in weight resulting from ice formed to trigger and terminate process
Inventor: GROSS ERICH
IPC: F25D21/02
Filed: 1980-04-19
Abstract: The defrosting control system is for evaporators of refrigeration and heat pump installations. The defrosting process is immediately triggered and controlled by the freezing process. It is based on the principle that the weight of the evaporator is increased as a function of the specific weight of the ice when ice is formed. A measurement is taken of the change in the weight of the evaporator to determine the amount of ice. This is used to trigger off and terminate the defrosting process. The evaporator is fitted with a weighing device with electrical contacts. The pressure signal is converted to operate a switch.
