Title: Bag filter cleaning device - with reciprocating tie rod and elastic elements on pulley to twist filter top
Inventor: BYSCHOVER LEONID NOSONOVITSCH
IPC: B01D46/04
Filed: 1977-02-02
Abstract: Bag filter for the removal of dust from gases is equipped with bags which are open at the bottom and closed at the top by a disc with a central stub shaft. Two elastic pulling elements are wrapped halfway around a pulley on the shaft from a fixed end, and the other end of each is attached in opposite directions to a tie rod. The latter can be reciprocated by a drive. This twisting motion followed by or combined with a backflushing flow of air restores the filtering quality of the filter cloth very efficiently (150-200%). The hydraulic resistance is greatly reduced and the filter capacity increased. The maintenance required is negligible and the filter is functionally reliable.

Title: Ozone prodn. appts. for use in cars - using glass cylinder with electrodes along the walls and rotating arms to create sparks and thus form ozone
Inventor: URBAN WERNER
IPC: C01B13/11
Filed: 1977-05-18
Abstract: Ozone for cars and other special purposes is produced in a device with a cylindrical glass body. Each end has a cover with openings for air inlet. It has a shaft down the centre which acts as a rotor with plastic discs carrying contacts. These line up with contacts on the inner surface of the cylinder. The shaft is connected to a drum on the outside of the cylinder contg. a contact breaker and a condenser, together with the requisite cable connections. The switching creates high voltage sparking. As the shaft rotates, the notched edge causes the contact breaker to operate when the electrical contacts line up in the cylinder. In this way the air stream is subjected to a series of spark discharges and ozone is formed. For use on motor vehicles where environmental pressure necessitates fume suppression. It can also be used to protect the vehicle driver from external influences by allowing an ozone rich stream to enter the vehicle and disinfect it. It can be used on the air intake to improve engine performance.

Title: Quick release accumulator terminal connector - has lever with eccentric pivot bearing against terminal clamp for emergency use
Inventor: HERTE GERHARD
IPC: H01R11/28
Filed: 1977-06-04
Abstract: The quick release connector is principally for motor vehicle accumulators, serving as a manually-operated interruptor in case of short circuit due to an accident. The fire risk can thereby be reduced. It replaces a conventional bolted connector. A lever with an eccentric pivot (a) bears against the terminal clamp (b). With the clamp on the accumulator terminal post (e) the lever is pressed into the horizontal position to exert pressure on the clamp and make good contact with the terminal post. A screw (d) and nut (c) serve to set the opening of the clamp (b) so that the lever action gives the required pressure on the terminal post. To release the clamp it is only necessary to pull the lever up.

Title: Microwave antenna with homogeneous dielectric lens - uses two concentric hemi-spheres with different radii as lens, with specified radius relation
Inventor: HOFMANN HOLGER DR ING
IPC: H01Q3/44
Filed: 1977-08-26
Abstract: The antenna is preferably intended for reception of electromagnetic waves, but can be used for transmission as well. The lens consists of two hemi-spheres, concentrically abutting with their planar surfaces. The radii (R1, R2) of the hemi-sphere are different and in such mutual ratio as to form of focus on the curved surface of the smaller hemi-sphere, when waves impinge on the greater hemi-sphere curved surface. The focus is located diametrically opposite the wave point of impingement. In the reception mode the energy of the electromagnetic waves can be output coupled at this focus, while in the transmission mode this energy may be coupled at this focus.

Title: HV potential measurement in encapsulated metal switch - has capacitive sensor consisting of burst disc and insulated plate
Inventor: LUEHRMANN HARRO DR ING
IPC: H02G5/06
Filed: 1977-12-28
Abstract: A device for measuring a high voltage potential in metal capsulated press. sealed high voltage switches has an electrode with the conductor carrying the high voltage. The capacitive voltage measurement avoids penetration of the pressurised gas volume and the use of a pressure tight connection. The electrode consists wholly or partly of a burst disc (7) sealing an opening (4) of the metal capsule (1) with intermediate insulating layers (8, 9). When a defined pressure is exceeded the disc bursts and relieves the pressure. A second metal sheet (13) is insulated from the disc.

Title: Variable picture size underwater television camera - uses synchronous switching in line and frame coil circuits to vary picture size in discrete steps
Inventor: RAY BRIAN
IPC: H04N5/228
Filed: 1978-01-13
Abstract: The underwater television camera has horizontal and vertical scan circuits that can vary the scanned picture circuits on the picture tube whilst in operation. Horizontal scanning is varied by switching additional inductances in series with the line coil or by switching the tappings of the line output transformer. Vertical scanning is varied by switching additional resistors so as to vary the current of the frame coil circuit. The switching takes place in discrete steps by synchronous operation of the double pole electromagnetic relays to give discrete changes of picture size. Further, it is possible to vary the position of the picture surface by varying the d.c. current in the line and frame coils from a high impedance source simultaneously with the variation of picture size.

Title: Speed control circuit for AC series motor - provides compensation for electrical supply voltage variations by use of trigger diode and series thyristor
Inventor: BRESSERS CORNELIS GERARDUS
IPC: H02P7/295
Filed: 1978-04-17
Abstract: The speed control circuit enables the voltage drop across the motor to be measured by an RC circuit (D1, R1, R4, C1) and used to control a trigger diode (D) which in turn triggers a thyristor (T) in series with the motor. The circuit comprises a stabilising circuit of a variable resistor (R2), and two capacitors (C2, C3) whose common point is connected to the trigger diode (D). In addition a reference diode (D3) is connected across the trigger capacitor (C1). The voltage on the trigger device is thus stabilised, eliminating mains fluctuations and their effect on speed.
