Patent GB-922108-A (GB)
Title: Pneumatic servomotor unit
IPC: B60T13/58
Filed: 1961-04-28
Abstract: 922,108. Fluid-pressure brakes. BENDIX CORPORATION. April 28, 1961 [June 30, 1960], No. 15393/61. Class 103 (1). In a tractor trailer fluidpressure brake servo system in which a movable wall carrying a control valve divides a housing into opposed power chambers, a coiled flexible tube in one power chamber connects the control pressure chamber of the control valve to an external connection to the trailer, and back - pressure means within the housing restricts the flow between the tube and one of the power chambers. In the released condition of the system high-pressure air fed through flexible tube 56 is held by a valve seating 54 of a spring 66, loaded poppet member 62 and atmospheric pressure from aperture 70 in the housing 22 passes by passage 72, open valve 76, passage 78 and flexible tube 80 to a connection 90, in the power chamber 30, leading by pipe 88 to the air motors 86 of the trailer brakes. On brake application, movement of the push-rod 46 moves the control valve C to close the valve seating 76 and open valve seating 54, thus passing pressure air from tube 50 through control chamber 60 and passage 78 to pipe 80. As pressure builds up in the pipe 88 and motor 86 a spring-loaded rubber faced valve member 104 is moved away from its seating 98 to supply pressure to the power chamber 30 to move the flexible wall 32 to the left and apply the tractor hydraulic brakes through a push-rod 40 and conventional master cylinder A. Thrust between the control valve housing 34, secured to the wall 32, and the rod 40 compresses a rubber reaction disc 45 into a space 84 to bear against the end 82 of the control valve C to provide " feel " and to make that valve self-lapping. Due to the back pressure valve 90 the trailer brakes are applied simultaneously or just before the tractor brakes. On brake release the valve C moves rightwards under the action of the disc 45 to open the seating 76 and allow trailer pressure air to flow to atmosphere through aperture 70. When the pressure in the pipe 88 has decreased to some 20 1b. per sq. in. less than that in the power chamber 30, air from the chamber 30 flows through holes 114 and 112 in the backing plate and rubber diaphragm respectively of the valve 104 and the pressures in the pipe 88 and chamber 30 drop together, allowing release of both tractor and trailer brakes.

Abstract: 478,485. Automatic control systems. ELECTROLUX, Ltd. (Platen Munters Refrigerating System Aktiebolag) June 4, 1937, No. 15536. [Class 38 (iv)] [Also in Groups XIII, XXIX, and XXXVII] Temperature.-Defrosting of the cooling clement of a refrigerating system is effected automatically by a device which integrates the amount of energy consumed in active periods by the driving motor 16 of a compression machine, Fig. 1. The machine is controlled in the usual manner by a thermostat 18 and operates intermittently to maintain a constant temperature in the cabinet 11. The electric integrating device shown in Fig. 1 comprises a constant speed motor 22 driving through reduction gear 24 and an adjustable friction disc 27 a rotary drum 30 of hard rubber or other insulating material having shaped contact strips 62, 63, with raised edge 66, Fig. 3, engaged by spring contacts 34.. 37. The motors are connected through a manual switch 48 and a thermostatic switch 20 to the mains 41, 42. With the parts in the position shown the auxiliary motor is connected independently of the compressor motor. When contact 36 engages the strip 62 the auxiliary motor runs with the compressor motor under control of the thermostat, and continues running after the compressor motor has been cut out by movement of an insulating surface 64 of the drum, into the path of the brush 35. Defrosting takes place until the drum again establishes the circuit to the compressor motor. The defrosting control may be disabled by the manual switch to permit manual control. The intermediate brushes 35, 36 may be adjusted to vary the running and defrosting periods. In a modification of this system shown in Fig. 5. the rotary switch drum 89 is driven through opposite friction clutches from the compressor 12 during active periods and from an auxiliary constant speed motor 79 during defrosting periods. Alternatively another auxiliary motor may be used in place of the compressor drive.

Abstract: 532,107. Directive wireless signalling. THIEMANN, W. H. A. (Bendix Aviation Corporation). May 25, 1939, No. 15598. [Class 40 (v)] An aerial for use with a horizontally-polarised "blind landing" beam consists of a centre-fed dipole with the two limbs 10, 11 bent back in the form of a loop, as shown in plan in Fig. 4. This provides a capacity " loading " and gives the aerial a substantially non-directional response, making it uniformally sensitive even when the plane is diving to land, or heading against a cross-wind. The aerial is fed at adjustable points 20a, 20b by a transmission line 19. The bentback limbs are adjustably secured in a common insulator sleeve 15, which is carried by a support 17, Fig. 5, mounted horizontally on the aeroplane. The aerial is preferably half a wave long, but a sliding bridge 12 near the feeding point allows the length to be adjusted. Figs. 6 and 7 show an alternative construction in which the two limbs 30, 31 are separated vertically, the inner ends 30a, 31a, being brought to a common intermediate plane and bridge at 32. The outer ends 30c and 31c overlap each other, as shown in elevation in Fig. 7, and are supported by bars 33, 33a and insulating pieces 34. The capacity loading between the overlapping parts allows the overall length of the aerial to be reduced for a given wavelength.

An hydraulic reciprocating motor comprises a piston 5 reciprocable in a cylinder 1 by alternately pressurizing and de-pressurizing the large cylinder space 2, while maintaining the smaller annular cylinder space 3 pressurized, the alternate pressurization and de-pressurization being effected by a distributing valve 10 actuated by fluid pressure influenced by the covering and uncovering of a throttled pipe 14 by the piston 5. As shown, the piston 5 is moving to the right by fluid from inlet 8 acting via the valve 10 and a conduit 6 on its left face F 1 . When the annular groove 16 is covered by the piston 5 pressure drops in pipe 14 through an adjustable throttle 13 and discharge pipe 9. This pressure drop also occurs in a chamber containing a face F 3  of the valve 10, whereby supply pressure acting on the opposed face F 4  causes the valve to changeover. Conduit 6 is therefore connected to exhaust and the piston reverses. When groove 15 is covered pressure builds up in the pipe 14 causing the valve 10 to return to its original position. In a second embodiment a plurality of longitudinally spaced grooves 15 are provided selectively connectible to the pipe 14 whereby the piston stroke is adjustable. In this embodiment changes inpressure in the pipe 14 control a pilot valve which controls the distributing valve 10. The throttles 11-13 may be adjustable to vary the working frequency.
