Title: Door closing mechanism with piston and cylinder - has piston operated rack and pinion with seats for external connections
IPC: E05F3/10
Filed: 1975-05-23
Abstract: The door closing mechanism has a long slender housing with a cylindrical bore which accommodates a spring loaded piston. This cylinder is filled with oil and the piston has a flexible seal. The closing mechanism can follow angular movements of the door. The housing (10) accommodates a piston which is connected to a toothed rack (26). This rack engages with a pinion with an axis at right angles to the rack. An external arm is connected to the pinion for accommodating door angular movements. The piston is loaded by a spring (19) and the piston has a one way valve for the oil in the cylinder. Oil flows through the piston when it compresses the spring. When the piston has reached one end of the cylinder then oil flow takes place through a pipe which has a valve.

Title: Signal receiver for carrier wave frequencies - has two modulator circuits 90 deg. out of phase in parallel and leading to adder stage
Inventor: BRAUN LOTHAR DIPL ING
IPC: H04B3/10
Filed: 1975-10-16
Abstract: The carrier wave frequency circuit consists of two modulators (11, 12) in parallel lines and each in series with a low pass filter (21, 22) and a further modulator (51, 52). The latter modulators are responsive to the same local oscillator voltage as the former. The output signals of the further modulators (51, 52) are collected by an adder stage (6), the output from which passes to another low pass filter (7), and from thence to a rectifier (8) and a final low pass filter. The filtering stages have the effect of removing the harmonics. The local oscillator signal to one of the parallel lines passes through a 90 deg. phase shift unit (1).

Title: Double:beat air control valve, for IC engine afterburners - has diaphragm operated by pressure from engine speed regulator to give automatic flow path selection
Inventor: GOTO KENJI
IPC: F01N3/22
Filed: 1975-11-10
Abstract: The control valve, comprises a cylindrical hollow body (9a) with a radial inlet (8) co-axial outlet (12a) and two further outlets (10b, 11b) on the cylinder axis. The upper of these (10b) connects with a radial pipe (10) in line (roughly) with the first outlet. The latter outlets (10b, 11b) are closed by sprung valves (10a, 11a) pipes from them lead to different parts of the exhaust system. The valves are free to slide on the reduced dia. portion (17d) of an axial spindle (17) fixed to a transverse diaphragm (15) dividing a chamber (14) on top of the valve body. Shoulders (17a, 17b)) on the spindle cause movement of the diaphragm to be converted into opening of one of the valves. Thsi movement is caused in turn by press. differences across the diaphragm, applied from a regulator unit which responds to engine speed through 2 connecting pipes (16, 16a).

Title: Fault current protective circuit - has summator transformer and has auxiliary windings feeding biasing generator and RC control
Inventor: EBEL HERBERT ING GRAD
IPC: H02H3/33
Filed: 1975-12-09
Abstract: A fault current protective circuit consists of a summing current transformer whose primary windings are formed by the main conductors of an AC single-phase or three-phase supply. The secondary windings of the transformer are connected to a trigger. There are auxiliary windings connected to a generator to produce an AC biasing magnetisation of the current transformer. The secondary windings are connected to a rectifier circuit. The frequency of the biasing magnetisation is large compared to the main frequency. A RC network is connected in parallel to the rectifier circuit. The time constant of the RC network is approximately equal to the period of the biasing oscillations. There is a discriminator circuit parallel to the RC network. When the voltage of the RC network drops below a limiting value it will produce a trigger pulse.

Title: Vibrator axial thrust absorber assembly - has resilient disc attached by force fit pegs to support disc for reduced wear
Inventor: FONTAINE MICHEL
IPC: B06B1/18
Filed: 1977-02-14
Abstract: The vibrator which is driven by a pressurised agent comprises a hollow outer cylinder and at least one inner cylinder whose axial thrust is absorbed by a support plate system.
