Patent GB-373799-A (GB)
Title: Automatic starting mechanism
Filed: 1931-06-12
Abstract: 373,799. Starting prime movers. STARTOMATIC CORPORATION, 1627, West Pico Street, Los Angeles, U.S.A. June 12, 1931, No. 17094. Convention date, June 12, 1930. [Class 38 (iv).] In an automatic starting system for internalcombustion engines in which an electrical starting circuit is provided with a solenoidoperated switch, the solenoid is de-energized by means of a control relay when the engine starts and while it runs under its own power and means delays the restarting of the engine if it stalls until it has come completely to rest. Closure of a switch 39 energizes the solenoid 36 and closes the switch 25 to connect the starting motor SM to the battery 10. Coil 59 is energized but the heavy starting current traversing the coil 28 prevents the retraction of plunger 47. When the engine starts the load on the starting motor is reduced and the current through the coil 28 reduces and the potential across the coil 59 increases so that the plunger 47 is drawn downwards. This moves a lever 53 having a roller 56 that engages a cam 46 on the end of a springy strip 44 and causes the contacts 42, 43 to open and break the circuit of the solenoid 36. This allows the switch 25 in the starting motor circuit to open. The plunger 47 is not released because the generator G driven by the engine builds up sufficient voltage to retain the plunger by means of a coil 64. Should the engine stop while the switch 39 remains closed, coil 64 becomes de-energized and plunger 47 is returned to its original position by a spring 48, thus releasing the strip 44 and cam 46. Since the cam 46 is set in vibration, contact 43 will open and close the circuit through coil 36 for a predetermined length of time before coming to rest against contact 42. The coil 36 is designed so that it is not effectively energized during this time, and the vibrating element is so designed that the time delay is sufficient to allow the engine to come completely to rest.

Filed: 1944-09-07
Abstract: 591,902. Retractable undercarriages. MILES AIRCRAFT, Ltd., and BARNES, W. B. Sept. 7, 1944, No. 17135. [Class 4] A retractable undercarriage comprising a pivoted leg having a member for carrying a trailing wheel, which leg swings in the general plane of rotation of the wheel to retract, and shock-absorber apparatus, is characterized by mechanism for pivotally displacing the member in said plane in relation to the leg for retraction. Fig. 1 shows a nose wheel unit in which the landing wheel 5 is carried by a trailing fork 3 pivotally connected at 4 to the lower end of the forwardly retracting leg 1. The lower end of a shock absorber 6 is connected to the fork 3 at 7, and at its upper end is connected at 10 to a link 8, the latter being pivoted on the leg at 9. The plunger of the' retracting jack 12 is also connected to the joint 10. During retraction the fork 3 swings forwardly about the pivot 4, thereby reducing the depth of the fuselage cavity for the reception of the leg and landing wheel. A drag link comprising two pivoted elements 15a, 15b, normally retains the leg 1 in its extended position, being maintained in alignment by a sleeve 16d which is slid clear of the folding joint by a spring link 17 at the commencement of retraction. In the embodiment shown in Fig. 2, the trailing fork 20 is swung forwardly about its pivot 21 during retraction of the leg 18 by a jack 24, the plunger of which is connected to a sector 26; which actuates a catch 32 and levers 34, 36, the lower end of the latter member being connected to the fork 20 by a pin-and-slot joint 37, 38. Fig. 4A shows a third embodiment in which fluid is supplied simultaneously to the retracting jack and to a space 45 above a piston 46 in the lower part of the leg 18, movement of the piston through a connecting rod 47 first releasing a catch 52 and then swinging the fork 20 about its pivot 21. Reference has been directed by the Comptroller to Specification 527,110.

Title: Fluid pressure operated disc brake
IPC: F16D55/228
Filed: 1953-06-20
Abstract: 735,748. Disc brakes. DUNLOP RUBBER CO., Ltd., and BUTLER, H. J. May 27, 1954 [June 20, 1953], No. 17136/53. Class 103 (1). In a disc brake an annular plunger and cylinder mechanism is positioned coaxial with, and on each side of, the brake disc to force a plurality of friction pads axially to engage the disc such that a pivotal connection is provided between the annular plungers and the friction pads to enable the pads to tilt to compensate for variation in wear of the pads and irregularities in the surface of the disc. In the embodiment illustrated applied to a transmission brake for a marine engine, an annular copper disc 1 is secured to the propeller shaft of the engine and two non-rotatable annular plates 3 and 4 are located one each side of the disc and bolted together by means of bolts 5 which pass through spring members 6. The two plates 3 and 4 are each provided with a plurality of equispaced substantially segmental shaped holes 7 extending axially therethrough. Slidable in the holes are pads of friction material 8 which frictionally engage an adjacent face of the disc. When fluid-pressure is introduced into the spaces between annular plunger 13 and the closed end of annular cylinder member 14, the annular plunger is moved towards the disc 1 and annular plates 12 integral with the plungers 13 force the pressure members 9 and the friction pads 8 into frictional engagement with the disc. Reaction of the two annular cylinders 14 is taken by U-shaped straps 16 and flexible protective members 20 are provided to protect the plunger and cylinder mechanisms from foreign matter. The friction pads have sufficient clearance in the holes 7 to tilt, due to the part-cylindrical recesses 10 in the segmental shaped pressure members 9 and the complementary-shaped members 11 having a flat base secured to the annular pressure plate 12, so that the friction pads 8 may tilt when so worn as to ensure that full frictional engagement is effected and also to permit the pads to tilt to accommodate themselves to irregularities of the disc due to excessive heat. Other embodiments are described; one enabling the invention to be applied to a plurality of axiallyaligned, axially-slidable brake discs, the other describing an arrangement for use with a single brake disc in which the pads may be secured to each of the segments of an articulated annular carrier plate which is itself non- rotatable and axially slidable relative to the disc, a pivotal connection being provided between each of the segments and the plunger.

Abstract: 1505415 Injection carburetters ROBERT BOSCH GmbH 28 April 1975 [24 May 1974] 17475/75 Heading F1B A fuel injection system for mixture-compressing, spark-ignition I.C. engines with continuous injection into the inlet manifold comprises a measuring element 2 arranged to be displaced through a distance proportional to the quantity of air flowing through the manifold against a restoring force and to thereby move a valve-member 14 for metering a fuel quantity proportional to the air quantity, and the restoring force is provided by a fluid-pressure  which is variable by a pressure control valve 42 having a valve diaphragm 45 acting as a movable valve-member and forming at least part of a wall of a pressure chamber 55 which is connected via a duct 56 to the inlet manifold downstream of the engine throttle valve 7 and connected via a restrictor 59 to another pressure chamber 58 but separated from the latter by a control diaphragm 57, the diaphragms being acted upon by respective springs 46, 63 and inter-connected by a link 65. Upon acceleration or deceleration, the consequential change in the pressure downstream of the throttle valve 7 is communicated directly to the chamber 55 but is communicated to the chamber 58 with a time lag due to the restrictor 59, the resultant temporary irregularity of pressure between the chambers altering the opening of the valve 44 to alter the restoring force acting on the end 15 of the valve-member 14, thereby providing the required alteration of the mixture richness. In conjunction with a restrictor 37, the valve 42 forms a variable hydraulic potentiometer connected between the fuel line 21 and a drain line 43 so as to supply fuel at variable pressure via a restrictor 39 to act on the end 15 of the valve-member 14. The pressure in line 21 is maintained constant by a relief valve 23. The time lag is variable by a further restrictor 60 in parallel with the restrictor 59 and opened by a bi-metallic spring 61 after the engine has warmed up. The spring 61 is heated by direct thermal contact with the engine or by an electrical heater. During the warm-up period, a bi-metallic spring 50 bears downwardly on the spring 46 to reduce the spring force tending to close the valve 42, thereby enriching the mixture, this effect being gradually reduced as the bi-metallic spring is progressively heated by an electrical heater 53.
