Patent GB-2197192-A (GB)
Title: Alternating pressure pad
Inventor: SCHILD ROLF
IPC: A61G7/057
Filed: 1987-10-23
Abstract: An alternating pressure pad has two or more layers (5,6) each made of two sets of cells (1,2) the cells of each set being inflatable independently of the cells of the other set. The layers are so arranged that the cells of the first set, of the uppermost layer, are immediately above corresponding cells of the first set, of the next layer down. Corresponding cells of the second set, of each layer, are also arranged to overlie each other in the same fashion. A control system may inflate a given cell simultaneously with inflation of the cell immediately above or below, and may inflate the two sets of cells alternatingly. Inflation may be carried out so that the average pressure in the pad as a whole is substantially constant over time. In addition means are provided to inflate all cells simultaneously with a constant pressure well below occulsion pressure without the risk of bottoming. <IMAGE>

Abstract: A signboard comprises a frame 1 constructed from channel-shaped members 2 made from a polyvinyl chloride (PVC) material and adhesively bonded together to form a square, in which the bases of the channel-shaped members form the outer perimeter of the frame 1. A supporting post 3 is bonded to the frame through one side thereof and extends across the central line of the frame to abut the opposite side, thereby also forming a brace member for the frame. A sheet 4, 5 of PVC material, upon which the sign information is printed, is adhesively bonded to each side face of the channel-shaped members 2 of the frame 1. The lower end of the post 3 may be secured to a wall or other support by brackets 6, 7 having holes 8, through which a screw or bolt passes and is screwed into the wall. <IMAGE>

Title: Ultrasonic welding technique, particularly for welding contact tab to battery electrode
Inventor: NG ANDREW S
IPC: H01M50/536
Filed: 1987-12-24
Abstract: At least one of the two contacting metal areas to be welded are in the form of void-containing disseminated units, such as a bundle of wires, the strands of a wire mesh, the fibres of a metallic fibre mat, or the component elements of a metal foam or sponge. This ensure that the necessary vibration can take place whereby frictional engagement at a multiplicity of points gives rise to heat and fusion with good mechanical and electrical connection. In one example (Fig. 1a) a bundle of wires (3) has a flattened contact area (4) of separated wires ultrasonically welded to a prepared electrode (1). In another example (Fig. 2b) a metal tab (10) is ultrasonically welded to a compressed zone (8) of a fibrous mat electrode (7) utilizing additionally a wire mesh element (9) whose area corresponds to that of the compressed zone (8). The electrode (7) may be a nickel fibre mat. <IMAGE>

Patent GB-2226472-A (GB)
Title: Image reduction/enlargement system
Inventor: ISHIWATA MASAHIRO
IPC: H04N1/387
Filed: 1989-12-04
Abstract: Image data from apparatus of the type where a line sensor is moved in a secondary scan direction while an image on an original is read by the line sensor in a main scan direction, e.g. facsimile, is passed to an image reduction/enlargement system comprising two one-line buffers 4, a circuit 2 providing interpolated values from the immediately adjacent pair of points on the same line, and a circuit 5 for controlling the interpolation circuit 2 and the writing of one line of image data into a buffer 4 while reading from the other buffer in ping-pong fashion. Selector switches 1, 3 act to configure the system so that during reduction, input data is first interpolated and then stored at 4 for direct read-out, while during enlargement input data is first stored at 4 and then passed via interpolator 2 to the output. The system requires little buffer memory and enables the same clock to be used for reading and writing the buffers; image shifting, repeating and reversal are possible. Vertical enlargement/reduction is accomplished by varying the speed of the line sensor.

Title: A slot valve for slot openings in walls or window frames
Inventor: MADSEN MOGENS
IPC: E06B7/02
Filed: 1991-09-10
Abstract: A ventilation slot valve that is both operationally safe and discrete in appearance is made of a flat channel sleeve (2), which is inserted in the slot opening so as to cover the edge thereof with a narrow flange (16), an associated oblong valve plate (14) in its closed position being located entirely inside the front opening of the sleeve.

The valve plate (14) may thus be brought into an open position by a successive pressure actuated release of its two ends, and it can be closed just by being pressed home for snap locking of the projector locks (46). The valve plate may have a discrete appearance without visible actuator means and almost as an integral part of the mounting surface.

Title: Producing corrugated sheets
Inventor: STEPHENS WILLIAM H
IPC: B31F1/28
Filed: 1992-01-14
Abstract: Corrugated board is produced by bonding an inner liner web to a corrugated intermediate web in a single facer 3 or 27. A second outer liner web is then applied in a double facer 16. A web of corrugated board 6 or 31 is then directed upwardly to a rotary shearing station 35 for cut-off as required, at the end of an order run. The web 6 or 31 is then directed upwardly to one of two streams which are led upwardly to a double level cut-off knife 45 which forms sheets cut to a desired size. The cut sheets are delivered to upper or lower stacking stations 50, 51 where they are downstacked on beds which are lowered and stacked sheets are led along roller conveyors to a mobile trolley. Any sheets 109 which are warped are passed between a pair of backing rollers 110, 111 and an adjustable bending roller 115 is urged downwardly against the bow of the sheet 109 to correct the warp. Dust generated in the cutting step is removed by ionising dust particles, vibrating the particles and removing them by vacuum. <IMAGE>

Title: A vibration dampener for dampening the vibration of a tubular member
Inventor: OBERMEYER FRANKLIN DELANO
IPC: G21C17/10
Filed: 1993-03-12
Abstract: A vibration dampener for dampening vibration of a tubular member, such as an instrumentation tube (170) of the kind typically found in nuclear reactor pressure vessels, which tube is received in an outer tubular member, such as a guide thimble tube (270), comprises an annular sleeve (320) which is attachable to the inside surface (280) of the guide thimble tube and which is sized to surround the instrumentation tube. Dimples (370) are formed in the interior wall (330) of the sleeve for radially supporting the instrumentation tube. The wall of the sleeve has a flexible spring member (380) disposed opposite the dimples for biasing the instrumentation tube into abutment with the dimples. Flow-induced vibration of the instrumentation tube will cause it to move out of contact with the dimples and further engage the spring member, which will flex a predetermined amount and exert a reactive force against the instrumentation tube to restrain its movement. <IMAGE>

Title: Cleaning a gas filter
Inventor: SEIBERT JEFFREY M
IPC: B01D46/54
Filed: 1993-04-28
Abstract: Filter elements 11 in a housing 10 are used to filter particles from waste gas before it is discharged from radioactive waste processing plant. When the elements are clogged they are cleaned by a reverse flow of liquid, delivered through valve V3, while venting off the gas, until housing 10 is full of liquid. Then compressed air is delivered through valve V4, above the liquid, and drain valve V6 is opened, to force the liquid through the filter elements and out of the housing. Elements 11 are HEPA or ULPA rated and preferably of sintered metal fibres. The backwash liquid may be water with or without surfactant, caustic soda, nitric acid or organic solvent, and helps to remove small particles by neutralising electrostatic forces holding them in the filter element pores. The liquid and air are both delivered to housing 10 through filters 41 and 44, which are rated at least as finely pored as elements 11. Used backwash liquid is collected for further treatment. Several housings 10 may operate in parallel and be cleaned in sequence. <IMAGE>
