Title: Windscreen wiper with intermittent sweep - with feedback control to relay amplifier for instant response
IPC: B60S1/08
Filed: 1975-09-30
Abstract: The windscreen wiper motor is coupled to the supply line by a control relay operated by a transistorised timing and amplifying circuit. The amplifier is coupled to the parking switch by a special feedback loop which ensures that the amplifier is reset when the wipers reach the end of the sweep. If the wiper switch is still on then the timing circuit provides the interval time delay. The system ensures that when the wipers are first switched on, with interval setting, then the first sweep starts immediately and not after a set delay. This provides instant response and does not deceive the driver that the wipers are faulty.

Title: Self-locking nut for adjustment of automatic gear boxes - is in form of plastics tube with longitudinal split
IPC: F16H25/20
Filed: 1976-06-23
Abstract: In order to adjust automatic gear changing transmission of road vehicles, it is necessary that the adjusting nut is self locking at any point along the length of a screw rod. This can be achieved by making the nut (1) from a resilient plastic tube with a thread (2) and a longitudinal split (3) extending the full length of the tube. For ease of adjustment, the gap (3) is forced open with a suitable tool and this allows the nut to rotate freely on the screwed rod (4). When the nut is in its required position, the gap is allowed to close so that the nut is locked to the rod.

Title: Electrostatic sprayer centrifugal atomiser - has spinning bowl with serrated or crenellated lip to inhibit premature coalescence of droplets
IPC: B05B5/04
Filed: 1976-12-28
Abstract: A high speed spinning bowl for the head of a centrifugal atomiser to generate small droplets for electrostatic spraying, has a serrated or crenellated lip to disrupt the flow from the bowl. The effect on the spray pattern is to suppress any regularly divergent or convergent streams from the bowl lip which could result in microvoids in the sprayed coating due to e.g. premature coalescence of some of the droplets. The notches around the lip may be of angular trapezoidal form and may be irregular in their form or spacing. The roots of the slats may be cut through the rim at an angle to the radius of the mouth of the bowl.

Patent FR-2348351-A1 (FR)
IPC: E05F15/56
Filed: 1977-04-14
Abstract: The loading spaces (35, 36) provided on both sides of the piston (38) of the actuating cylinder (37) are, in the case of pneumatic actuation, alternately connected to a compressed-air source (11) via a respective solenoid valve (2, 3) assigned to them or to the atmosphere via a throttling nozzle (31, 32). The actuating cylinder for closing and opening the door (6) is effective in both directions. Furthermore, each loading space (35, 36) is connected to the atmosphere via a respective non-throttled connection, in which a piston-controlled shut-off valve (17, 18) is located. The piston (19, 20) of the shut-off valves can be loaded, counter to the force of a spring (25, 26), in the closing direction of the shut-off valve by the pressure of the other respective loading space (35, 36). When one loading space is loaded with pressure, the compressed air of the other loading space escapes in a throttled manner, whilst the non-throttled connection is opened via the shut-off valves (17, 18) and manual actuation of the doors is guaranteed, without obstruction, when the solenoid valves (2, 3) are simultaneously located in a position opening their outlet valves (15, 16). The door (6) can thus be actuated by hand in a unrestrained manner, but the door movement is damped in the case of pneumatic actuation.
