Patent GB-2169135-A (GB)
Title: Improvements in electric power control switches
Inventor: SONG KI WON
IPC: H01H3/00
Filed: 1985-11-15
Abstract: The switch comprises an operating lever 11 adjusted by a control cam 24. In one position of the control cam 24 the operating lever 11 opens a first switch 8 to 10. in other positions the first switch 8 to 10 is closed and a motor M rotates a timing cam 6, which passes between blades 16 and 17 of a second switch, intermittently opening the switch. The second switch 16 and 17 is mounted on the operating lever 11 so that adjustment of the control cam 24 moves the blades 16 and 17 and alters the proportion of the each revolution of the timing cam 6 for which the second switch is closed, and hence the average power delivered to a load through the second switch. As illustrated, two electric power control switches 7 to 24 and 7' to 24' share a common motor M and timing cam 6. If only one first switch 8 to 10 or 8' to 10' is closed the timing cam 6 rotates but the other second switch 16' and 17' or 16 and 17 is held permanently open. <IMAGE>

Title: Video image magnification system
Inventor: DOUBLE IAN R
IPC: G06T3/40
Filed: 1988-10-26
Abstract: An input video signal is digitised, 10, and stored, 11. The portion of the image to be magnified is defined by its centre point and address generator 14 calculates the number of pixels to be read out according to the required magnification. The store, 11, is read out column by column directly and via a delay, 20, to an interpolator, 17, which generates a fixed number of interpolated pixels (Fig. 4). A data selector 21 selects the appropriate number of interpolated pixels for the degree of magnification selected. The pixels, now at increased line density, are again stored, 25, and read out line by line with repetition of pixels according to the selected magnification. A D-A converter, 29, generates an analogue signal which is filtered, 30, to have the effect of interpolation in the line direction. <IMAGE>

Title: Fuel injection pump
Inventor: THORNTHWAITE IAN ROY
IPC: F02M59/02
Filed: 1989-07-10
Abstract: A fuel injection pump of the rotary distributor type has a fluid pressure operable piston 12 connected to a cam ring of the pump for the purpose of timing adjustment. Flow of fluid into or out of one end of the cylinder containing the piston is controlled by a valve member 29 slidable in a bore in the piston. The valve member is pressure balanced and is positioned by means of control pistons 41, 43 in response to variation in fluid pressures. The piston is subject to reaction forces when the cam followers of the pump engage the leading faces of the cam lobes and the tendency for piston movement is resisted by a ball valve 39. Opposite reaction forces occur when the cam followers move over the crests of the cam lobes and piston movement is resisted by restricting liquid flow from the other end of the cylinder through the clearance 24B or the restriction 24C. <IMAGE>

Title: Cleaning reactors used in the gas-phase treatment of workpieces
Inventor: MOLLER RAINER
IPC: C23C16/44
Filed: 1989-08-02
Abstract: A method of cleaning reactors for the gas-phase treatment of workpieces is characterised in that a suitable etching gas or etching gas mixture is passed alternately or simultaneously through the reactor, which is to be cleaned, during the process routes provided for substrate treatment as indicated by arrows at the base of the reactor and along a second gas route as indicated by arrows at the sides of the reactor, which serves for providing a flushing gas cushion on the reactor wall during substrate treatment and which is formed by lining a reactor from the gas-phase treatment of workpieces with a gas-permeable second wall system 8 which is arranged at a defined distance from the outer reactor walls 1 and thus forms a filling cavity, into which a flushing gas flows during the substrate treatment and an etching gas or etching gas mixture flows during the cleaning cycle, emerging into the reactor through the surface of the gas-permeable second wall system and by extraction channels which are spatially and functionally separate from the process gas extraction. In the specific embodiment NF3 is admitted in a cleaning cycle after a layer of SC3N4 has been deposited, which decomposes into fluorine ion, atomic fluorine and nitrogen during the cleaning cycle. This route after the cleaning cycle has been completed is isolated and changed to a flushing gas feed 9 or flushing gas extraction 10.

Title: A linear displacement sensor
Inventor: BRUNNING ALAN DAVID
IPC: G01D5/165
Filed: 1989-12-27
Abstract: A linear displacement sensor makes use of a known flexible, force and position sensing linear potentiometer (Fig. 1) and bonds this potentiometer into a U-shape before mounting the opposite ends on components 28, 32 which are linearly movable relative to one another. As the components move, the fold between two arms of the U-shape is forced to roll along the length of the potentiometer and this causes the point of electrical contact to move at the same time. <IMAGE>
