Patent GB-2129404-A (GB)
Title: Sliding drawer assembly
Inventor: STRUTT JOHN RICHARD
IPC: G03G15/00
Filed: 1982-09-21
Abstract: A drawer assembly includes a drawer (1) slideably mounted on a frame, and a locating tab (61) for positively locating the drawer in its home position. The locating tab is preferably kite-shaped, having narrower leading and trailing portions (62, 63) and a wider intermediate portion (64), and extends rearwardly from the drawer in the direction of sliding movement of the drawer. A tab-receiving arrangement on the drawer frame comprises two rollers that are spring-urged towards one another, and sensing means operated by the tab to supply a signal to indicate that the drawer is in its home position. Once the intermediate portion (64) of the tab has passed the rollers of the tab-receiving arrangement, the drawer is positively pulled into its home position. The assembly is particularly applicable for copy sheet trays in a xerographic copier.   <IMAGE>

Title: Improvements in joints for connecting together hollow frame members
Inventor: HIBBERT ERIC
IPC: F16B7/18
Filed: 1983-01-27
Abstract: First and second hollow frame members 1 and 2 respectively extending normal to one another are connected by a joint including two joint blocks 21 spaced apart to prevent local distortion of the members 1,2 by bending or twisting forces to which the joint may be subjected. The joint blocks 21 have edge flanges 23 engageable with complementary grooves 17 within the hollow section of the second member 2 and are secured by screws 26 so as to project from the end of the second member 2. The projecting ends of the blocks 21 are received within a channel 9 extending lengthwise along one side of the first member 1 and are secured by bolts 32 so that the end face of the second member abuts the side of the first member. By this arrangement the joint may be provided at any position along the length of the channel 9. The members 1,2 and joint blocks 21 are of uniform section along the length thereof and can be made from elongate extruded sections cut to length to form a door or window frame of any required size. <IMAGE>

Patent GB-2126858-A (GB)
Title: Method of compressing data
Inventor: OKAI TSUKASA
IPC: B41B19/00
Filed: 1983-09-12
Abstract: To compress data derived by tracing the outline of a character or symbol, normally comprising at least one closed loop having straight and curved parts, a plurality of sampling points along the outline are selected. Those on straight or lightly curved parts are disregarded while those on strongly curved regions are retained. Retention or rejection of each sampling point Pn is determined by comparing with a selected constant k the product of the length l of the straight line segment to the next point Pn+1 and the angular charge  theta  in direction between the segment from the preceding retained point Pn-1 and the segment to the succeeding point Pn+1. <IMAGE>

Title: Vehicle door lock system
Inventor: WARD MARCUS JOHN SCOTT
IPC: E05B65/20
Filed: 1984-07-21
Abstract: A vehicle door lock system comprises a latch mechanism connected to a door handle by a single push-pull control cable 14. The control cable has three operating positions; an intermediate unlocked position (2); push to lock (position 3); and pull to release (position 1). In the form of handle shown in Fig. 5A, a toggle button 90 pulls the outer sheath 18 relative to the inner cable 16 to lock the latch (position 3). The latch may be unlocked either by return (clockwise) movement of the button or by pulling handle 92 which, when fully rotated, releases the latch. In the latch construction shown, a relative pull on the inner cable causes nipple 62 on its end to rotate release lever 26 and hence to free conventional pawl 30. Reverse movement to position 3 rotates locking lever 40, moving its pin 36 into part 44 of an aperture in the release lever, thus disabling its actuation by external means via end 38. <IMAGE>

Title: Method and device for monitoring or controlling the welding process when welding workpieces with the arc-welding method
Inventor: GAWLIK NORBERT
IPC: B23K9/073
Filed: 1984-12-07
Abstract: In a method of monitoring arc-welding of two workpieces to be joined at a welding seam, radiation from the instantaneous welding zone or welding arc is spectroscopically analysed during welding to provide a monitoring signal indicative of whether each workpiece has adequately fused at the instantaneous position of formation of the welding seam. The method may be used in controlling welding using a welding torch adjustable during welding by having the monitoring signal further processed to provide a control signal to the welding torch to adjust its position if necessary during welding to ensure that each workpiece is adequately fused. Apparatus for carrying out this method preferably comprises an emission spectrometer 5, an optical-fibre wave guide 7 for receiving radiation from the instantaneous welding zone or welding arc and capable of transmitting it to the spectrometer, and a microprocessor 13 comprising an evaluation system and control circuit capable of being programmed to analyse the presence and/or intensity of spectral lines to provide the control signal for the welding torch. <IMAGE>

Title: Shower apparatus
Inventor: WOOD RODERICK CHARLES ROWLAND
IPC: A61H9/00
Filed: 1985-09-02
Abstract: A shower apparatus arranged when required to produce a pulsating flow of water from the showerhead, comprises a cold water inlet 11 which is connected to a pair of inlet valves 12 and 13. The valve 12 is arranged to remain open both when the apparatus provides a pulsating flow of water and when it provides a substantially constant rate of flow of water whereas the valve 13 only remains open when the apparatus is producing a constant rate of flow of water, said valve 13 being arranged to open and close in succession when the apparatus is set in a pulsating mode of operation. The valves 12 and 13 have outlets which are connected to a heat exchanger (17) for heating water which subsequently passes to the showerhead and there is also provided a third valve 23 which is conveniently controlled by means of a solenoid and which is arranged to be open when the shower apparatus is in its pulsating mode and thereby maintain the total volume of water flow and therefore the temperature thereof, said valve 23 being closed when the shower is set to produce a constant rate of flow of water. <IMAGE>

Title: Aerosol actuator and cap
Inventor: BULLOCK KENNETH ROSS
IPC: B65D83/14
Filed: 1985-10-10
Abstract: An actuator 1 includes a jet 29 engageable with a valve stem 3 of an aerosol 1 and the nozzle 20 of the actuator is moved in direction D with respect to a mounting portion 4 to operate the aerosol valve and provide a spray of aerosol material from said jet on to a surface in contact with the open outer end 23 of the nozzle 20 when the aerosol with actuator fitted is pushed on to said surface. The actuator has a skirt portion 31 which provides a desired spacing between said jet and said surface to be sprayed, a stencil 24 providing the required mark on the surface. The actuator nozzle 20 is reversible to engage in a compact manner over said aerosol valve to provide a cap therefor. <IMAGE>

IPC: F16F9/02
Filed: 1986-01-17
Abstract: In a gas spring the piston rod 3 is introduced through one end wall of the cylinder 2 by means of a guiding and sealing device 5,6. An annular separating piston 7 sealingly engages the piston rod 3 and the internal surface of the cylinder 2. A sealing liquid is contained within an annular sealing chamber 11 located axially between the sealing and guiding device 5,6 and the annular separating piston 7. A body of pressurized gas 10 is provided on the other side of the separating piston. The pressurized gas acts onto the separating piston 7 such as to create pressure of the sealing liquid within the sealing chamber 11, but additionally a separate spring 12 is provided which acts on the separating piston 7 in parallel with the pressurized gas such as to increase the pressure of the sealing liquid beyond the pressure of the pressurized gas. Spring 12 could be replaced spring elements of other type, eg. a secondary annular gas chamber. <IMAGE>
