Abstract: 892,453. Aeronautical cameras with optical gyroscopically-controlled orientation indicators. SOC. FRANCAISE D'OPTIQUE ET DE MECANIQUE. May 15, 1959 [May 16, 1958], No. 16793/59. Classes 97(1), 97(3) and 98(1). A device for determining the orientation in space of an aerial survey photographic camera in an aircraft comprises a gyroscope with its rotor mounted on the support for the camera so that the mobile parts of the gyroscope mounting means are entirely balanced about the centre of gravity of the rotor and the spin axis of the rotor is free from influence by movements of the support, and means for indicating the orientation of said camera with respect to the spin axis of the rotor. As shown, deviations of the support 2 and camera 1 from the horizontal cause movement relatively to the plane mirror 6 carried by the freely mounted gyroscope 5 having a vertical spin axis of the light source 7, reference grid 8 and the remainder of the optical system 10, 9 and 13, 14 so that a focused image of the grid 8 is moved relatively to the centre of a photographic film 16 indicated by an image of a central cross engraved on a plate 17 overlying the film. The exposure of the film 16 in the auxiliary camera is effected in synchronism with the exposure to the terrain in the main camera 1, either by momentarily illuminating the lamp 7 or by means of a shutter, under control of contacts closed by the main camera shutter or of mechanism controlled by a photo-cell responsive to the terrain exposure, and the film 16 is fed in step with that in the main camera 1. In a modification the auxiliary camera may be arranged to form the graticule image in a margin or corner of the terrain photograph, synchronized shutters being employed. A second gyroscope with its axis horizontal may be used to give indications of displacement in a horizontal plane. Instead of a plane mirror 6, a concave or convex mirror or a prism may be used.

Title: Improvements in buffing and draft-gear for vehicles, more particularly railway vehicles
IPC: B61G7/10
Filed: 1931-06-10
Abstract: 380,120. Combined buffing and drawgear for railway vehicles. AMERICAN STEEL FOUNDRIES, 410, North Michigan Avenue, Chicago, U.S.A. June 10, 1931. No. 16874. Convention date, Feb. 19. [Class 103 (v).] In a combined friction buffing and drawgear for railway vehicles the transversely disposed wedge blocks 18, 22 pass through slots 36 in the underframe sills 10, and the coupler 38 is provided with an integral shank or yoke 40 that embraces the wedge blocks and thereby secures the coupler to the sills. Adjacent to the slots 36 the sills are reinforced by a casting 11<1> comprising a forward striking surface 14, draught and buffing stops 12, 13, and a coupler supporting surface 15 fitted with a wear plate 16. The transverse wedges 18, 22 co-operate with longitudinally disposed wedges 25, 26 which are adapted to be displaced laterally against the action of springs 31 embracing a connecting-rod 30. In order to allow the coupler to pivot freely when under either draught or buffing stress the yoke 40 at its rear end is formed with a part cylindrical surface 42 engaging a corresponding surface 24 on the rear wedge 22, while at its forward end the yoke has a concentric surface 43 adapted to abut against a correspondingly curved surface 21 on the front wedge 18. In addition, the coupler is permitted a certain amount of vertical play by making the opening in the casting 14 of a sufficient height and by increasing the depth of the slot in the yoke 40 at the outer or forward end of the latter. In assembling the gear the yoke and coupler are inserted into the casting from the front, and then the friction elements are introduced from the outer sides of the sills 10. In a modification the yoke is introduced from underneath the casting and is formed with a lug which coacts with an internal projection on the casting to prevent the gear from being completely separated from the underframe in the event of the gear collapsing.

Title: Hydraulic control valve
IPC: F15B13/04
Filed: 1959-05-19
Abstract: 859,658. Valves. NEW YORK AIR BRAKE CO. May 19, 1959 [Sept. 17, 1958], No. 16926/59. Class 135. A valve suitable for controlling a double-acting differential-area piston motor 72 for positioning the bucket of a loader used in earth moving equipment has a slidable valve member 35 urged by a spring 67 to a neutral position in which ports 22, 24 communicating with an inlet 12 connected with an hydraulic pump are placed in communication with an outlet 13 leading to a reservoir to unload the pump and ports 19, 26 communicating with the two ends of the motor 72 are isolated. When the valve member is moved to the right the communication between the inlet 12 and outlet 13 is interrupted, the lower side of the motor 72 is connected to the inlet through ports 48, 49 communicating with an axial bore in the valve member, and the upper side of the motor is connected to exhaust through ports 52 which open to a second axial boring communicating with ports,51, 53 which, in this position of the closure member, communicate respectively with exhaust ports 23, 28. Movement of the closure member to the left of the neutral position causes reverse motion of the motor 72 by connecting the upper side thereof with the inlet through ports 52, 53 and the lower side with exhaust through ports 49, 48, the latter then communicating with an exhaust port 17. The lefthand position of the valve member is determined by engagement of an abutment 68 with a stop 66 but the valve member may be moved beyond this position by the application of sufficient pressure to force a shoulder on a sleeve 65 past an elastic, split-ring 63 so that the central land 41 of the valve member enters the bore between ports 21, 22. In this position both sides of the motor 72 are connected with each other through ports 51, 53 and are also connected with ports 21, 25 which are interconnected by means of a passage 33 incorporating a restriction 56 leading to the port 22. By this means the motor 72 is free to descend under the weight of the bucket owing to the unequal volumes on the two sides of the piston of the motor 72 due to the piston-rod the rate of descent will be limited by the rate at which fluid can pass through the restriction. The inlet 12 to the valve incorporates a relief valve 34. A check valve (not shown) is incorporated within the closure member adjacent the ports 48 to prevent return flow of fluid from the conduit 73 when the closure member has been moved to the right but before the pump has developed sufficient pressure to operate the motor 72.

The tubes 11, 17 pass through a framework 20 and an arm 24 pivoted at its rear end to the framework, extends between the two tubes so that by moving the arm towards either side of the framework the corresponding tube 11 or 17 is flattened. During milking, tube 17 is flattened against the side of the framework, the tube 11 then applying vacuum to the container to draw milk into the container, and for emptying the container, the teat cups are removed from the cow, the tube 11 is flattened leaving the tube 17 open to convey milk to the milk delivery pipe, air entering the container through the teat cups. The framework comprises a plate 26 having convergent side edges whereby arm 24 is retained in either of its tube-closing positions, the plate being vertically adjustable so that flexible tubes of varying diameter may be used. The tube 11 may also be closed by bending the tube 9 on itself and inserting the bent portion between projections 28. A further tube 14 connected to cups 15 for use when washing the equipment is provided and during the milking operation this tube is bent upon itself and inserted in a loop 16 to hold it closed.
