Patent DE-2453942-A1 (DE)
Title: Capacitor with metallised plastics film - with improved self sealing capacity and stability over a long period
Inventor: EPPLE RICHARD DIPL PHYS DR
IPC: H01G4/224
Filed: 1974-11-14
Abstract: Capacitors with metallised plastics films are manufactured by placing the capacitor bodies in pots in a dry oxygen atmosphere, and enclosing them in the dry oxygen atmos. This prevents molecules of water from entering the capacitor, and due to the use of oxygen the possibility of conductive prods. of disintegration occurring in case of a dielectric breakdown is reduced. The process may be used on all capacitors where these problems can occur.

Title: Air conditioning diffusion ventilator - has oblong chamber with end wall slots for T-section supporting bar
Inventor: DAY THOMAS LOGAN
IPC: F24F13/072
Filed: 1974-11-22
Abstract: The ventilator has an oblong slot for fitting to a T-section bar on the ceiling, and a housing with an oblong air chamber (12).

Patent DE-2527421-A1 (DE)
Title: Safety lowering device for people or loads - has cable drum braked when gas ram pressure equals liquid ram pressure
Inventor: KANKKUNEN KAUKO VALDEMAR
IPC: A62B1/12
Filed: 1975-06-20
Abstract: The braking mechanisms of the device comprises two interconnected cylinders, one of which is filled with a liquid and the other with a gas. Lowering is performed by unwinding a cable or rope from a drum. Rotation of the drum causes, by means of a gear system, the piston of the cylinder filled with a liquid to move, thereby pressing liquid into the second cylinder and moving the piston of this cylinder against the mounting counter pressure of the gas cushion. When this counter pressure equals the force exerted on the piston of the first cylinder by the cable load the unwinding stops. By providing the device with an additional bearing and means for selectively coupling the cable drum to said gear system, the device may be used as a safety device when working at high heights.
Patent DE-2529652-A1 (DE)
Title: Electronic con.rol for windscreen wipers - with washer control for set interval after end of wash sequence
Inventor: GILLE GUENTHER
IPC: B60S1/48
Filed: 1975-07-03
Abstract: The windscreen wipers are operated by a motor controlled by an electronic interval timer. This has an astable switching circuit with NPN input transistor and PNP output transistor in cascade. The system provides a simple parking control by shortin out the motor circuit when the park setting reached. It also provides a controlled interval sweep, with controlle delays between sweps. The washer control is linked to the circuit in such a way that the wipers are activated when the washer is switched on. A charged capacitor provides sufficient signal to operate the wipers after the washer is switched off, for a set period, controlled by the delay time of the capacitor.

IPC: F01C1/356
Filed: 1975-09-16
Abstract: The annual cylinder (RZ) engine has a number of pistons (K1, K2) attached to the rim of a disc (S) mounted on a central spindle (A), via a slot (N) in the cylinder wall. The rim of the disc seals this slot, except for a cutout section adjoining the leading edge of each piston which acts as an exhaust port. Disc valves (V1, V2) equal in number to the pistons subdivide the cylinder. They are electromagnetically actuated to permit piston passage. Working fluid is supplied from the middle of the disc through internal passages to inlet valves (E2) at each piston. Alternatively, or in addition inlet valves (E1) may be fitted to the cylinder. Lubrication points (O) are provided in the cylinder walls, unless lubricant can be carried in the working fluid. If fixed partitions are fitted instead of the disc valves, the engine becomes an oscillating one.

Title: Valve for well testing and sampling string - has closure bias increased by annulus pressure and is operable by increasing annulus press
Inventor: FARLEY DAVID LEE
IPC: E21B34/00
Filed: 1976-04-15
Abstract: A valve for use in a well testing tool is arranged to be exposed to the pressures interiorly and exteriorly of the tool and while these pressures are equal assumes an open position in which it allows the exterior pressure to act to increase the bias applied to an actuator, e.g. a test valve actuator, in the tool. Upon setting a packer below the tool and increasing the pressure exteriorly thereof, the valve assumes a closed position in which further increases in exterior pressure are not effective to increase the bias applied to the actuator but are effective to displace the actuator against the existing bias, e.g. to open the test valve.
