Title: Bags
Inventor: OLSEN GEOFFREY THORVALD
IPC: B31B39/00
Filed: 1989-04-26
Abstract: A bag, for spectacles or spectacle lenses, is formed of two superimposed layers (1,2) of different materials, the two layers extending from one side (3) of an opening (4) of the bag to a closed end (5) of the bag formed by a folded over portion of the two layers, and from the folded over portion to the other side (6) of the opening. The run (7) of the superimposed layers extending from the one side (3) of the opening (4) to the folded over portion (5) is sealed at its edges (8, 9) to the opposite edges (8', 9') of the run (10) extending from the other side (6) of the opening (4) to the folded over portion so that layer 1 constitutes an outer case and layer 2 constitutes an inner lining. In one form, Figure 3, the opening (4) is at the end of the bag remote from the closed end. In another form, Figure 4, both ends (5A and 5B) of the bag are closed and the opening (4) is intermediate the ends. Reversible closure pockets (11, 12) comprise return portions (2A, 2B) of inner layer 2. Layer 2 comprises plain high density polyethylene, and layer 1 comprises low density bubble film or foamed polyethylene. Apparatus for forming the bag of Fig 3 comprises a first supply roll (20) for layer (1) and a second wider supply roll (21) for layer (2), the layers meeting at a tensioning roller (23) and thereafter passing in superimposed relationship between upwardly inclined plate (24, 25), over guide rollers (26A, B), between downwardly inclined plates (27, 28), between tension controlling rollers (29, 30) and to a transverse sealing device. Before roller (23), layer (1) runs over roll (21) against its direction of rotation and creates a static electricity charge such that the edges (2A, 2B, Figs 1B, 1C) of the wider layer (2) fold around the layer (1) during passage through the plates (24, 25). A V-portion (27c, Fig. 2) at the lower end of plate 27 causes the layers to be folded about a longitudinal line. <IMAGE>

Title: Recoilless air gun
Inventor: HUTCHISON ROY
IPC: F41B11/644
Filed: 1989-12-15
Abstract: In a recoilless air gun in which opposing pistons 12, 13 are arranged to be propelled simultaneously in opposite directions when the gun is fired, to compress a charge of air to propel a projectile, the pistons are attached to opposing locations on an endless chain or flexible belt 18 extending around spaced apart reversing pulleys 20, 22, so that as the attachment point of one piston to the chain or flexible belt 18 moves in one direction along one of the runs thereof between the pulleys, the attachment point of the other piston moves in the opposite direction along the other of said runs. The pistons are propelled by respective similar springs (15) so that the effective masses of the springs are also balanced and the flexible belt or chain is under negligible tension and therefore subject to relatively little wear. The pistons may be connected to the belt or chain via respective connecting links 30, 32 whose inclination relative to the runs may vary. In order to minimise loads on the trigger sear, in the cocked condition of the gun the line of action through link 30 may be close to the rotary axis of pulley 20. <IMAGE>

Title: Removing dust from used foundry sand scouring apparatus
Inventor: SATMER FRANZ
IPC: B22C5/10
Filed: 1990-11-28
Abstract: A method and apparatus for regenerating foundry old sand is proposed, by which method combined impact and shearing stress of the sand grains occurs within a rotating treatment drum (1), with simultaneous removal of dust (2) from the drum by suction. The nonburned bentonite and carbon components can be reused, as can the regenerated material, i.e. core sand. Environmental pollution and quantities for dumping are thus drastically reduced. The treatment drum (1) contains a stirrer which rotates in the opposite direction to the drum. Removal of sand by the suction is restrained by labyrinth passages between the stirrer and a suction hood. The dust (2) is separated by a cyclone (3), and filter (4), into reusable dust and waste dust. <IMAGE>

Patent GB-2242175-A (GB)
Title: Power steering valve assembly mechanism
Inventor: KOBAYASHI SHIGEKI
IPC: B62D5/083
Filed: 1991-02-04
Abstract: The valve assembly comprises an input shaft (1), a pinion shaft (2), a valve sleeve (3) and a torsion bar connecting the input shaft and the pinion shaft. The center line (C1) of the cylindrical bore of the valve sleeve (3) intersects the center line of a radially extending pin hole (3a) in the valve sleeve (3) and is displaced from the center line (C) of the valve assembly toward the side of the sleeve opposite to the pin hole (3a). The valve sleeve is thicker at its periphery adjacent to the pin hole, thereby increasing the engagement length ( beta ) of a drive pin with the pin hole. Consequently, the pressure-receiving area of the pin hole is increased, and the unit area engagement force of the valve sleeve is thus reduced. The bending moment on the drive pin is also reduced, which adds to the durability of the drive pin. Since a bearing stress is thus reduced, a driver never feels unexpected reaction, due to wear, applied to a steering wheel while the driver is manually turning the steering wheel. <IMAGE>

Title: Propulsion by self aligning foil
Inventor: HAZELWOOD RICHARD ANDREW
IPC: B63H1/36
Filed: 1991-11-30
Abstract: Propulsion is achieved using one or more foils each mounted on a shaft about which they are free to rotate. The design of the foils and their mountings ensures that they are self aligning to adopt a constant angle of attack. This provides a high lift, low drag, efficient means of propulsion. A single hydrofoil f, mounted on a bent shaft s, which oscillates about a nearly horizontal axis at the stern of a boat, Fig 1. provides a sculling action, and can be controlled to provide efficient steering and propulsion, forward or backward, with one hand. Multiple foils, mounted to form a screw propeller or turbine, provide an automatic variation of pitch without complex control mechanisms, applicable where the cost of fully optimal control is not warranted. As well as propelling craft through air and water, fluid can be pumped, or energy extracted with good efficiency in a range of conditions. In a further embodiment two pivoting, self adjusting foils replace the two fixed blades of a kayak paddle. <IMAGE>

Title: A levelling workstation
Inventor: RIGBY JACK WILLIAM
IPC: A47B9/04
Filed: 1992-11-17
Abstract: A workstation 10 in which raising or lowering of each edge of the work surface 12 is coordinated so that a level work surface is maintained. Screw-threaded actuators 34 are attached between the work surface 12 and its supporting frame 26, each of which have extendable driving members 36 to raise or lower the work surface 12 with respect to the frame 26. The movement of the two driving members 36 is synchronised by mechanical linkages 38 at each end of the work surface, formed of a pair of elongate members 40, 42, member 40 being pivotally connected at one end to the frame 16 and at the other end to the second member 42. The free end of member 42 is rigidly attached to a shaft 44 rotatably carried by the frame 26. Thus, vertical movement of one end of the work surface 12 becomes rotational movement of the shaft 44 which causes a corresponding movement in the linkage at the other end. <IMAGE>
