Title: Structural boards
IPC: B32B3/30
Filed: 1974-04-19
Abstract: 1467964 Laminates NIHON SUNPLY CO Ltd 19 April 1974 17182/74 Headings B5N and B5A A structural board of thermoplastics material comprises at least two spaced parallel layers each having a multiplicity of ribs on a face of the layer, the ribs on the layers respectively being disposed in intersecting relationship, with the ribs on one layer being integrally united with the ribs of the other layer at the crests of the respective ribs where the ribs intersect, the ribs on at least one of the layers having a sinuous or zigzag shape. The board may consist of two layers having ribs on their inner faces or two outer layers having ribs on their inner faces and an inner layer having ribs on both faces, the inner layer optionally comprising two layers each having ribs on one face thereof and opposite faces which are flat and which are integrally united together. The ribs may have crosssections which are substantially normal to or inclined to the faces of the respective layers on which they are formed. The ribs may have widths which are substantially uniform throughout their heights, which are reduced toward the crests of the ribs or which have enlarged crests which may be of circular or rectangular crosssection. The ribs may be equidistantly spaced apart or may be arranged into a plurality of groups which are spaced apart from each other by distances greater than the separation between adjacent ribs of a group. The ribbed layers may be produced by extruding thermoplastics material 40 through annular orifice 35 in die 30 between die blocks 32 and 33, die block 32 having formed on its outer peripheral wall serrations 36 so that ribs 42 are produced on the inner surface of tubular form 41, which extend curvilinearly if rotary die 30 is driven alternately in opposite directions. Tubular form 41 may be flattened into sheet form or longitudinally slit and fused to another web produced in the same manner. Foamed thermoplastics material may be provided between the layers, e.g. by extrusion, to partially or fully fill the spaces between the layers. The structural board may be used for packaging, floorings, roofings, partition panels, sound absorbing or heat insulating material, linings for vehicles, cushioning for benches and chairs and panels for mounting pictures and photographs.

Title: Improvements in or relating to loading mechanism for refuse collectors
IPC: B65F3/18
Filed: 1945-07-05
Abstract: 602,107. Refuse-collecting vehicles. SCAMMELL LORRIES, Ltd., HUGH, P. G., and WATTS, L. D. July 5, 1945, No. 17183. [Class 108 (i)] [Also in Group XXX] Hydraulic operating-mechanism for the loading mechanism of a refuse collector of the type comprising a travelling refuse scoop includes a driving shaft mounted in a hydraulic pressure chamber and a pair of hydraulic cylinders attached to and communicating with the interior of the chamber and containing pistons attached to opposite ends of a chain passing over a sprocket which is mounted on the driving shaft within the chamber, so that rotary movement can be imparted to the shaft in either direction by creating a difference of pressure between the chamber and the head end of one or other of the cylinders, according to the direction of rotation required. The invention is shown as applied to a refuse collecting vehicle with loading mechanism of the kind described in Specification 467,479 in which a scoop 7 is moved vertically in a refuse receptacle 2 and horizontally along the top of the vehicle by cables 8. The latter are wound on pulleys 9 at the ends of a cross-shaft and are actuated by pistons working in pairs of hydraulic cylinders 21 at the sides of the vehicle, the pistons being connected by chains passing over sprockets on the ends of the shaft. Pressure liquid for the system is supplied by an engine-driven pump 28 from a reservoir 29, and a distributing valve 27, to a conduit 26 for operating the scoop 7, or to a conduit 36 for operating vehicle tipping mechanism, which may be of the type described in Specification 595,516. The scoop-operating mechanism is controlled by a valve 31, shown in the neutral position in Fig. 8, and in all positions of which pressure liquid is supplied by the conduit 26 to the casing 17, 18 enclosing the sprockets and cross-shaft, to tension the chains connecting the operating pistons. To drive the scoop 7 forwardly, the valve 31 is moved downwardly, connecting the conduit 33 and two of the pistons to pressure, and the conduits 34, 35 to exhaust. To reverse the drive, the valve 31 is raised, thus connecting the conduit 34 and one only of the pistons to pressure, and the conduit 33 to exhaust. By this means an increased speed is obtained during the return movement of the refuse scoop. The mechanism for operating the control valve 31 is as described in Specification 602,108.

Filed: 1970-04-10
Abstract: 1305643 Continuous casting MONSANTO CO 10 April 1970 [11 April 1969] 17187/70 Heading B3F A crucible assembly 13, Fig. 1, or 70, Fig. 4, for spinning a melt having a viscosity no greater than unity, e.g. Cu, Fe or steel, has a base-plate 14 or other member 65, 67 with an extrusion opening 19 or 66 coaxially aligned with an aperture in a shelf 11 or 62 which is of material such as pyrolytic boron nitride or graphite which is thermally anisotropic and is more conductive in planes 22 or 77 perpendicular to the direction of extrusion so that there is even heat distribution to the base-plate 14 or member 65 from the periphery of the shelf 11 or 62. The anisotropic shelf (32) may be separated from the crucible base (35) by a graphite or beryllia member (33) which, like a member 68 in Fig. 4, reduces immediate contact of melt and film-forming gas into which it is spun. The extrusion opening 19 or 66 may be the spinning orifice or receive an insert defining the orifice. There may be several openings 19 in the base-- plate 14. An induction coil 17 or 74 heats the periphery of the anisotropic shelf 11 or 62 and the crucible 13 or 70 (by way of a susceptor 12 or 69) and melts the spinning charge in it. The crucible is of alumina, beryllia or zirconia and the contacting surfaces of a base cover-plate 15 or base 71 and a wall member 16 or 72 are lapped mating surfaces. For greater control of melt temperature, the crucible may have an upper reservoir (42. 43). There may be two anisotropic shelves 61, 62. To increase the heating of the shelf aperture, the pitch of the induction coil is increased and to restrict the heat flow to the upper portion of the shelf, the inner coil of the water-cooled inductor 74 is mounted on and in electrical contact with a copper support 76 gapped to prevent short circuiting of the inner coil. The upper and lower parts of the inductor may be separately powered. There may be an annular slot (51) in the bottom of the shelf (32) to restrict heat transfer in the lower shelf portion. Reference has been directed by the Comptroller to Specifications 1,153,577 and 1,197,972.

Title: Improved fluid-pressure power steering mechanism for motor vehicles
IPC: B62D5/06
Filed: 1955-06-15
Abstract: 771,157. Vehicle power steering. GENERAL MOTORS CORPORATION. June 15, 1955 [July 19, 1954], No. 17217/55. Class 79(5). In a vehicle fluid-pressure power steering mechanism comprising a control valve 26, Fig. 1, and a servomotor, one part of the control valve 26 is connected with a manually movable arm 16 and the other part is connected with the wheel steering linkage 46 and through an auxiliary linkage 42, 40, 34, 30, 28 with the manually movable arm 16 so as to be moved at a different rate to the first part of the valve, the auxiliary linkage including an expansible and contractible link 34, 40 incorporating the servomotor. As shown in Fig. 1, a steering shaft 10 rotates the arm 16 about a pivot 18 by means of a gear 14, the part 20 of the arm 16 being connected to a stud 24 and the other part 22 being connected by the link 28 to the two-armed lever 30 pivoted at 32. The lever 30 is connected to the piston 36 normally hydraulically locked in the cylinder 40 which in turn is connected at 124 to the idler arm 42 pivoted at 44, the arm 42 and the control valve 26 being interconnected by the rod 46 which is also connected to the steerable wheels through links 48, 50 and steering arms 52. The ends of the cylinder 40 are connected by pipes 76, 78 to the control valve 26 which also has a conduit 86 leading from an accumulator 88 charged by a pump 90 from a reservoir 92 which is connected to the valve by a conduit 94. The stud 24 on the arm 20 is held between ball seats 54, Fig. 3, in a plunger 56 slidable in a sleeve 58 of the valve 62, the sleeve 58 being secured to or integral with the rod 46. A plug 104 is threaded onto the sleeve 58 and has a flange 108 to limit its axial movement. A spring 167 disposed between one of the seats 54 and a plug 100 urges the plug 100 against the plug 104, the plug 100 being located on a spindle 96 secured at 98 to a valve element 66 having positively lapped lands 68, 70 co-operating with parts in a casing 60 secured to the conduits. In operation, counterclockwise rotation (for example) of the shaft 10 causes clockwise rotation of the parts 16, 30. Due to the hydraulic lock in the cylinder 40 the idler arm 42 is rotated clockwise to move the rod 46, but such movement is less than that imparted to the stud 24 through the part 20 due to the leverage employed and hence relative movement takes place between the valve elements 60, 66 to pressurise one end of the cylinder 40. In a modification, Fig. 4, the steering gear box 14<SP>1</SP> carries a rocker arm 134 connected by a drag link 136 to a two-armed lever 138 pivoted at 140 to the vehicle frame 142, the lever 138 being connected at 158 to a link 154 connected to a two-armed lever 154 pivoted at 156 and carrying a piston rod 150. The cylinder 40<SP>1</SP> is connected to a valve casing 62<SP>1</SP> having a ball jointed connection at 148 with a bell crank lever 128 connected to track rods 132. The movable valve element in the casing 62<SP>1</SP> has a short shaft 146 having a pin and slot connection 144 with the lever 138.
