Abstract: 1,120,490. Vehicle hydropneumatic suspensions. DAIMLER-BENZ A.G. 13 Dec., 1966 [14 Dec., 1965], No. 55820/66. Heading B7D. A control arrangement for a pressure medium operated regulating device 19, such as for controlling the level of a vehicle oleopneumatic suspension, comprises a piston-like control slide 11 which is responsive to a disturbance, such as a vertical movement of an axle 14, through spring means 12 and which controls the connection of a pipe 23 leading to the regulating device 19 with either a pressure medium supply pipe or to an outlet pipe, valves 24, 26 operated by the control slide being provided in the pipe 23 and the supply pipe at least. As shown, the valves 24, 26 comprise spring-loaded balls 28 movable by push-rods 29 actuated by conical or spherical surfaces 31, 32 of the control slide 11 and the outlet pipe communicates with a passage 33 in the wall of the control slide cylinder 10 controlled by the outer periphery of the conical surface 32. The push-rods 29 may be disposed normal to the conical surfaces 31, 32 or in the direction (34) (Fig. 2, not shown) of the resultant of the normal force and frictional force between the push-rod and surface. On upward movement of the control slide the valve 26 is opened, permitting pressure medium from a reservoir 25 to pass to the valve 24 and thence to the device 19. On downward movement of the control slide the valve 24 and the annular passage 33 are opened, permitting discharge of pressure medium from the device 19.

Abstract: 1,159,922. Compacting material into containers. R. J. PIOCH. 19 July, 1966 [24 Aug., 1965], No. 55963/67. Divided out of 1,159,921. Heading B8E. [Also in Division F1] Refuse material tipped into a ram chamber 18 is pushed forward and compacted into a rectangular opening 24 in one end of a container 20 by means of a rectangular ram 16 of a width substantially equal to the width of the opening 24 and of a height substantially less than that of the opening. The ram extends in its protracted position into the container an amount at least equal to the difference in height of the ram and the opening. The upper edge of the opening is defined by a beam 25 which mounts a cam 44 to move a cam follower 42 when the beam is deflected by articles jamming between the top of the ram and the beam. The cam follower 42 is attached to and will rotate a hollow shaft 38 mounted parallel to the beam and one end of which mounts an arm 45 to engage a switch 46. The switch 46 is incorporated in the circuitry for the hydraulic ram 16 to stop the ram should the beam deflection become excessive. Further excessive deflection detectors comprise an arm 55 which extends diagonally on one side of the ram chamber and has its lower end attached at 59, 59<SP>1</SP> to vertical and longitudinal ram chamber reinforcing guiders 50, 51 respectively. The upper end of the arm is free to move relative to the ram chamber and mounts a switch 52 which engages a plate 56 attached to a shaft 60 extending through the shaft 38, whereby any undue bulging of the ram chamber will deflect the upper part of the arm and so close the switch 52 which in turn stops the ram. A similar arm 66 mounted on the other side of the ram chamber has the upper end attached to the shaft 60, whereby to move the plate 56 away from the switch to stop the ram when that side of the ram chamber bulges. A similar arrangement operates at the rear of the ram chamber. The ram operating means 11 is situated below a platform 14 extending between the dockside 10 and a shoot 15 feeding the rain chamber. The front of the ram chamber has a flange to locate the container opening and also has a releasable means 21 to connect the ram chamber to the container.

Abstract: 1,244,183. Photographic processing apparatus. INTERNATIONAL POLAROID CORP. Dec. 2, 1968 [Dec.1, 1967], No. 56992/68. Heading G2A. A self-developing camera, e.g. as described in Specification 1, 207, 000, has a pair of static members defining a pressure generating gap, one of the members 20 defining the gap having at the gap defining portion 46 a radius of curvature of the order of five to eight times the radius of curvature of the gap defining portion 44 of the other member 22.

The laminate may be produced by extruding a stream of polyethylene or ethylene-vinyl acetate copolymer containing not more than 8% by weight of vinyl acetate and a stream of ethylene-vinyl acetate copolymer containing 10-45% by weight of vinyl acetate from the respective outputs of two extruders, feeding the streams to an inflation die, thermally welding together the two streams before or after the exit of the die to form a composite layer and pressing the composite layer on to a metal foil at an elevated temperature such that the latter copolymer is in contact with the foil. The composite layer may be extruded as a tube and cut to form a sheet or the tip ends of the two extruders may be connected to a single T-die. One or both surfaces of the composite layer may be subjected to treatment to improve its adhesive properties, e.g. by corona discharge. The laminate may be used as a shielding layer for a communication cable, the laminate being disposed around an aggregated core covered with a bundling tape of polyester or polyethylene film and an outer jacket of polyethylene being disposed on the outer surface of the plastics layer of the laminate.

Abstract: 588,843. R÷ntgen-ray apparatns. DUDLEY, L. P. C. J. Nov. 11, 1944, No. 22260. [Class 98 (i)] Stereoscopic X-ray photographs are made by passing the X-rays through the subject on to a fluorescent screen, the image being photographed through an optical grid composed of parallel strips of opaque material alternating with strips transparent to light, the grid being moved in a direction transversely with respect to the longitudinal axes of the grid strips and the subject and X-ray source being moved relatively to one another in a direction substantially at right angles to the longitudinal axes of the strips. X-rays from the source 1 pass through the subject 2 and fall on the fluorescent screen 3, the image being photographed by the camera 4 which may be either a still or a kinematographic camera. (Mirrors, prisms or the like may be interposed.) A grid having fine transparent strips alternating with opaque strips is mounted either in the camera or between the fluorescent screen and the camera, preferably close to the former. For parallex panoramograms the opaque strips are preferably wider than the transparent strips ; for stereograms they are preferably of equal width. As the source is moved to positions 1<1>, 1<2>, the screen and camera are moved to corresponding positions 3<1>, 3<2> and 4<1>, 4<2> respectively. Alternatively, the source remains stationary and the subject is moved, e.g. by rotation. In making a parallax panoramogram, the grid movement and the exposure are continuous or a series of separate exposures is made with the grid moving a distance equal to the width of one opaque strip whilst the source or subject is moved between its extreme positions. For parallax stereograms, two exposures are taken in different positions. Specification 564,490 is referred to.

This ring 48 is axially movable under the action of springs 80 to disengage the clutch when support blocks 54 are moved by centrifugal force against adjustable springs 60. A latch 82 is moved by a . spring 84 to latch the ring 48 and hold it out of engagement when the ring is allowed to so move by the radial movement of blocks 54. The teeth 50 are shaped as shown in Figs. 4 and 5 with one set having concave sides (Fig. 5) with which concave sides of the other set register (not shown) and in cross-section (Fig. 4) the teeth are provided with chamfers 90 and a gable bottom 92 to strengthen them. The coupling is described incorporated in a drive between an electric motor and a pump, so that if liquid is forced through the pump and the motor driven thereby the coupling prevents the motor from overspeeding.
