Title: Stabilized Optical System
IPC: G02B27/64
Filed: 1967-07-26
Abstract: 1,151,559. Sighting devices. BELL & HOWELL CO. 26 July, 1967 [12 Sept., 1966], No. 34447/67. Heading F3C. [Also in Division G2] The line of sight of cameras, telescopes, binoculars, gun sights, missile guidance systems or other optical apparatus is stabilized by an optical wedge formed of two lenses 6, 50, Fig. 5, lens 6 being fixed relative to the apparatus and lens 50 being movable parallel to itself, without tilting movement in a plane perpendicular to the optical axis of lens 6, by an amount corresponding to the movement of the apparatus. As shown applied to a cine camera, an electric motor 14 having a drive-shaft 180 drives a shaft 142 through a sleeve assembly allowing a slight amount of misalignment of the shafts 180, 142. The shaft 142 terminates in a sphere 150 whose centre is located at the intersection of the pivotal axes of a member 80 in gimbal 24 and of the latter in casing 4, respectively, the sphere 150 having a circle of contact with the closed but apertured end of a sleeve in a rotor support arm 116 and point contact with a spring-pressed plug. The rotor 115 is rotatably mounted within member 80 by means of bearings on its support arm 116. When the camera vibrates, the axis of rotor 115 tends to remain fixed in space and thus it moves angularly relative to shaft 142. If this angular movement is about an axis perpendicular to the plane of Fig. 5, due to the coupling members 99, 100 connected to member 80, a parallelogram linkage 68, 68<SP>1</SP> is pivoted about 70, 70<SP>1</SP>, to slide the plate 52 carrying lens 50, parallel to itself, the motion being non-tilting by virtue of lugs 54 on plate 52 sliding between roller bearings 58F and 58R. If the angular movement of the axis of rotor 115 relative to shaft 142 is about the axis passing through gimbal pin 26, the member 80 causes gimbal 24 to rotate about such axis and links 68, 68<SP>1</SP>, cause corresponding sliding motion of lens 50 in the perpendicular direction. Thus any relative motion of the rotor 115 about either axis causes corresponding sliding motion of the lens 50.

The cam 111 is urged towards its retracted position by centrifugal force. The pistons 101 have conical ends engaging a tapered surface on the cam 111 so that the pistons are rotated; the piston ends may however be rounded. The cam surface 115 may be shaped to alter the timing of injection according to the delivery. Fuel is supplied under pressure to the inlet channel 74 which feeds the cylinders through individual valves which may be cup-wash type valves as shown in Fig. 7 or flexible ring type as shown in Fig. 15. Each pump cylinder is connected directly to an injection valve having a flexible ring valve 138. The pistons 101 are returned to engage a shoulder 118 by the feed pressure but a light return spring may also be provided.

Title: Improvements relating to fluid pressure braking systems
IPC: B60T8/32
Filed: 1935-12-14
Abstract: 467,217. Fluid-pressure brakes. KERSHAW, A. G., SIMMONS, A. W., and WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. Dec. 14, 1935, No. 34784. [Class 103 (i)] In a fluid-pressure brake system for railway and other vehicles, one or more brake cylinders are controlled-by one brake pipe and another cylinder or cylinders by an additional brake pipe extending throughout the train, the pressure in the additional brake pipe being controlled in accordance with the speed of the train. Figs. 1 and 2 show the equipment on the locomotive and tender of a train respectively. The usual vacuum brake pipe 1 with driver's valve 6 is connected to vacuum brake cylinders on each carriage. A second brake pipe 2 connected to other brake cylinders on the carriages is normally exhausted through a check valve 9 and the pipe 1. The pipe 2 is also connected to the pipe 1 through a speed responsive valve device 10. Compressed air brake cylinders 11, 12 on the locomotive are supplied by a reservoir 13 through valves 21, 26 under the control of the vacuum in the pipes 1, 2 respectively whereby these cylinders are charged proportionally to the fall of the vacuum in applying the brakes. The reservoir 13 is charged from a main reservoir 16 through reducing and check valves 14, 15. Compressed air brake cylinders 28, 29 are provided also on the tender and are controlled by the pipes 1, 2 respectively through valves 30, 31, the supply being from a reservoir 32 connected to the reservoir 16 through pipe 3 and a check valve 37. When, to apply the brakes, the vacuum in the pipe 1 is reduced, the cylinders 11, 28 and those on the carriages that are directly connected to this pipe are operated in the usual manner. The vacuum in the pipe 2 will be reduced to an extent dependent upon that in the pipe 1 and upon the action of the device 10 the reduction being greater, the greater the speed, and this reduction will effect a corresponding application of the brakes by the cylinders 12, 29 and those on the carriages that are connected to the pipe 2. The upper and lower chambers of the carriage cylinders connected to the pipe 2 may be connected to each other through a restricted port so that the initial braking effort of these cylinders may gradually diminish to zero. A restricted port may also be provided between the brake pipe chamber and the vacuum reservoir chamber of the valve 26 so that the effect of the cylinder 12 also diminishes. The braking effort of a cylinder or cylinders may also be rendered dependent on the load. Thus in the case of the tender, the hydrostatic pressure of the water in the tank 38 may operate a pilot valve 39 controlling relay valves 40, 41 interposed in the pipes 34, 36 connecting the valves 30, 31 to the cylinders 28, 29.

Abstract: 1502268 Crop spraying HORSTINE FARMERY Ltd 31 July 1975 [7 Aug 1974] 34878/74 Heading AID [Also in Division B2] Apparatus suitable for spraying crops comprises a rotatable disc 15, Fig. 2, a pipe 22 for supplying flowable material to the disc and a fixed mask 16 substantially concentric with the disc, said mask having slots 16c such that part of the flowable material centrifuged from the rotating disc is obstructed at a plurality of locations spaced about the axis of rotation of the disc and part of the flowable material passes through the slots. The material obstructed by the mask flows into a frustoconical portion 16b thereof and thence onto an unmasked rotatable disc 25 secured on the same shaft 12 as the disc 15; the unmasked disc produces an uninterrupted spray pattern on which the interrupted spray pattern produced by the disc 15 and mask 16 is superimposed. If desired, spray material obstructed by the mask 16 may be recirculated to the disc 15 via the pipe 22. The sum of the circumferential widths of the slots 16c is preferably substantially equal to the sum of the widths of the tongues between the slots so that the volume of spray material passing through the slots is approximately half the total volume of material centrifuged from the disc 15. Rods (24), Fig. 1 (not shown), adjacent the leading edge of each slot prevent small droplets produced when the spray pattern impinges on the edges of the slots from issuing from the mask; if desired, the leading edge of each slot may be turned inwardly and the mask tongues deflected so as to increase the angle between the inner mask suface and the droplets impinging thereon. The discs 15, 25 may be flat or dished and may be made of metal or plastics material. The mask 16 is preferably rotatably adjustable about the shaft 12. Crop-spraying apparatus. Figs. 4 (not shown) and 5 depict crop-spraying apparatus in which five spray assemblies are mounted on a carriage. A liquid supply tank 35 is provided with supply pipes 22 to each assembly and the flow of liquid is controlled by a metering device 36 which is itself controlled by a chain drive 37 connected to a wheel 38 so that the volume of liquid delivered to the spray assemblies is dependent on the speed of the carriage. An air compressor 39 discharges air downwardly through nozzles (40), Fig. 4 (not shown) to assist penetration and distribution of the droplets within the crop.
