Title: Improvements relating to windscreen wipers
IPC: B60S1/18
Filed: 1946-10-18
Abstract: 630,695. Windscreen-cleaners. TRICOFOLBERTH, Ltd., and BODDY, J. Oct. 18, 1946, No. 31091. [Class 138(i)] Control mechanism for a windscreencleaner comprises an actuating shaft 6 mounted on a carriage 4 bodily displaceable transversely of the shaft, and a transmission shaft for driving the shaft 6 through a clutch which is mounted on and movable with the carriage and adapted to be disconnected when the carriage is shifted, provision being made to ensure that disconnection of the clutch takes place only when the cleaner is in the desired parking position outside its normal arc of wipe. In the arrangement shown in Figs. 1 and 2, the U-shaped carriage 4, which rests freely on parallel runners 3 on the baseplate 1. carries the shaft 6 transversely of the runners 3. The shaft 6 is provided with a crank 8 for driving the cleaner through links, a flexible rack or other means, and is driven through a worm wheel 9 by a worm 10 which is mounted on the carriage and continuously driven from any moving part of the engine or gearing. The worm wheel 9 is free to rotate on the shaft 6 and is provided on one face with clutch teeth 12 for engagement with similar teeth on a dog 14 which is axially slidable on the shaft 6; a compression spring 15 normally, urges these parts into disengagement. On its face remote from the worm wheel 9, the dog 14 is provided with a boss 16 on which a ring 17 having projecting pins 18 is slidably mounted. The forked end of a bell-crank lever 19 pivoted at 20 on the carriage 4 has slots for engagement with the pins 18 and its opposite slotted end engages a pin 22 on the baseplate 1. When the wiper is operating, the carriage is at the end of the baseplate which causes the lever 19 to hold the ring 17 against a flange 23 on the boss 16 and thereby effect engagement of the clutch parts 12, 14 for driving the crank 8. When the carriage is moved on the runners, the lever 19 moves the ring 17 away from the flange 23 so as to permit disengagement of the clutch parts 12, 14, and the displacement of the axis of the crank 8 changes the sweep of the wiper. The clutch parts are not actually disengaged until a key 25 on the carriage 4 registers with a radial keyway 24 at the end of the boss 16, and, when this occurs, the drive of the crank is stopped and the wiper is arrested in the desired position.

Abstract: 690,213. Hydraulic valves. ELECTROL, Inc. Dec. 3, 1948 [Dec. 3, 1947], No. 31396/48. Class 135. A manually-operable selector valve unit for controlling the supply and exhaust of pressure liquid to and from a double-acting jack, operating, e.g. the retractable landing gear of an aircraft comprises a pressure-responsive by-pass valve, closing when the supply pressure rises above a predetermined minimum to isolate the two ends of the jack cylinder and opening when the pressure is below this minimum to connect the two ends of the jack and permit direct manual operation of the jack piston. As shown, a casing 10, Fig. 2, having supply and return ports 42, 44 respectively and jack ports 24, 25, houses a ported sleeve 32 within which is slidably mounted a plunger 31 having lands 34, 35 co-operating with sleeve ports 36, 38 connected to the jack ports 24, 25. A transverse casing bore 15 slidably mounts a spring-loaded piston by-pass valve 21 subjected on its under face to supply pressure through a port 12 and having a recess 23 permitting the interconnection of ports 24, 25. Opposite sides of a dashpot piston 56 mounted on the plunger 31 and slidable in a cylinder 63 are connected by ports 64, 65 and non-return check valves 78, Fig. 3, having small holes 79 therethrough permitting a restricted flow when one or other of the check valves are closed to retard movement of the piston 56 and so prevent chattering or abrupt movement of the plunger 31. Opposite ends of the cylinder 63 are connected to the return port 44 to ensure that the cylinder is always filled with liquid. On the pressure of the liquid supplied to the ports 42, 12 exceeding a value determined by the spring 22 the valve 21 is raised to cut communication between the ports 24, 25. On then moving the plunger from its neutral position, Fig. 2, one end of the jack is connected to pressure liquid supply whilst its opposite end is connected to exhaust. Should failure or partial failure of the pressure liquid supply occur, the valve 21 will be urged downwards by its spring to open communication between the ports 24, 25 and so permit transference of liquid from one end of the jack to the other and direct manual operation thereof.

Abstract: 1,019,901. Automatic temperature control. HOOVER Ltd. Aug. 31, 1962 [Sept. 7, 1961; July 31, 1962 No. 32193/61 and 29431/62. Heading G3R. [Also in Divisions H2 and H3] An electric converter circuit (Fig. 1) includes a thyristor 10 with an inductance which may be or may include an induction heater 11, in series with it, and in parallel with it a series resonant circuit having a capacitor 15 and an air cored inductor 16. The circuits may be used for an ultransonic vibration generator, in which case the capacitor 15 is a ceramic capacitor transducer forming the load. The induction heater is in the form of a flat spiral and operates by inducing eddy currents in the base of the pot standing on it. A low hole storage diode 17 may be connected in parallel with the heater. When the d.c. supply is connected at terminals 13, 14 the capacitor 15 becomes charged. On triggering the thyristor current flows both from the supply and from the charged capacitor through the thyristor and the load. As the circuit is oscillatory the current reverse after a time, and the thyristor cuts off. The power supplied is therefore a function of the frequency at which the thyristor is triggered. The oscillator 18 which provides trigger pulses for the thyristor may be free running as described below with reference Fig. 2 or it may be triggered by a pulse derived from the induction heater circuit at the moment it turns off (Fig. 3 not shown). In the triggered form a frequency of 25kc/c is possible. Control circuits. The main oscillator comprises transistor 25 and transformer 26 connected as shown to a supply derived from the main d.c. supply resistor 41 and Zener diode 42. The frequency is determined by the potential of point 35, which is controlled by variable resistor 36 and the temperature regulating circuit. Capacitor 40 causes the circuit to start up slowly so that the protection circuit (below) has time to operate if the heater is not loaded The temperature sensitive resistor 57 passes a current, dependent on the heater temperature, which supplies the tunnel diode oscillator comprising tunnel diode 50 and transformer 51. The rectified output of transformer 51 is applied to point 35 (to control the main oscillator) and this output is a function of the current in the temperature sensitive resistor 57. Protection. If the pot is removed from the heater the supply is turned off by a manually reset relay 21, 22 connected across the heater through a diode 47 and current limiting inductor 46.

Filed: 1954-11-09
Abstract: 755,494. Feeding sheets. NOON, A. W. Nov. 9, 1954 [Nov. 9, 1953], No. 32378/54. Class 100 (1). In sheet-separating apparatus the end portion of the top sheet 28 of a stack of sheets 16 is raised towards the periphery of a suction roller 20 by blowing air across the top of the pile to create a sub-atmospheric pressure above the end portion of the sheet 28. Air blown from a tube 30 is directed upwardly, by a deflector 32 thereon, into a circumferential recess 26 in the roller 20. The roller 20 is driven about a fixed axis, as by a belt and pulley, and has two radial holes therein which communicate with a transverse hole 40 leading to one side of the roller. A fixed arcuate vacuum chamber 34 in engagement with the side of the rotating roller causes the sheet 28 to be sucked against the periphery of the roller when the hole 40 is covered by the chamber, and the sheet is removed from the pile and fed to a conveyer 37. As shown, the pile 16 is pressed upwardly against a fixed arm 10 by a spring arm 12. A cross-pin 14 prevents the top sheet being prematurely separated from the pile. In a modification, to prevent two sheets being separated together from the pile, two devices are described above are arranged as shown in Fig. 4. The device on the left is remote from the pile and creates a low pressure area which will serve to peel the excess sheet from the one being carried away from the pile by the device on the right.
