Title: Delayed action-self-priming cells
IPC: H01M8/24
Filed: 1979-09-04
Abstract: A battery of self-priming cells 6 is disclosed comprising insulating plates (14) each having a peripheral flange (15) and a strip (27a) which is parallel to and spaced from a rectilinear edge (15b) of the plate. The strip (27a) on each plate fits into a groove (28) in an adjacent plate so that a conduit (29) is formed between each adjacent pair of plates (6) through which electrolyte passes when priming takes plate. The strip (27a) is shorter than the rectilinear edge so that the bottom of the conduit (29) opens into a compartment (16) formed between the adjacent pair, in which the electrodes (7) are placed. The provision of the conduit (29) reduces the possibility of two adjacent element being short circuited by the electrolyte once priming is complete. It also enables more rapid filling of the elements as it enables purging of the air upwards. <IMAGE>

Title: X-Y addressable workpiece positioner
IPC: G03F9/00
Filed: 1980-02-21
Abstract: A semi-conductive wafer 30 to be aligned with the image of a mask 98 is movable in X-Y directions on a work stage 24 having an array of positioning indicia 45. An enlarged image portion of the positioning array is projected onto a sensor stage 46. The X and Y image coordinates are sensed through windows 53 and compared with a reference address to derive an error output for moving the workpiece to the reference address. Border indicia are similarly sensed through respective windows 115 for reference. The approximately stationary sensing stage is movable relative to the enlarged image of the positioning array for interpolating between the X and Y coordinates of the sensed address to permit an operator to precisely super-impose the image of a pattern on the wafer with a mask image thereby zeroing the reference system to the interpolated value. The machine then sequentially steps the interpolated (zeroed) reference position address by predetermined increments. <IMAGE>

Patent GB-2073651-A (GB)
Title: Moulding apparatus
IPC: B29C45/02
Filed: 1981-04-01
Abstract: In a multi-cavity, flashless mould for moulding small rubber articles, such as seals for use in vehicle hydraulic braking systems, each mould cavity (6) is defined between a piston (10) received in a bore (12) in a first rigid platen (4) and an insert (8) firmly mounted on a second rigid platen (2), the rear ends of the pistons (10) being exposed to the pressure of a common body of fluid contained within a closed chamber (44) so that, when the mould is closed, the pistons will retract into their bores on engagement by the respective inserts until all the pistons are engaged with the inserts. The fluid body in chamber (44) then supports the full moulding pressure whilst biasing the pistons (10) against their inserts (8) with substantially equal forces. Instead of a common body of fluid the pistons may be acted upon by respective Belleville springs. To assist in preventing flash, the mould cavity (6) is separated from a surrounding flash groove (54) by very narrow land surfaces (50, Fig. 2) e.g. about 0.1 to 0.2 mm wide. <IMAGE>
Patent GB-2080549-A (GB)
Title: Methods and apparata for measuring capacitances and locating breaks in cables and conductors
IPC: G01R31/08
Filed: 1981-04-13
Abstract: In a method of measuring capacitance or capacitance difference, or of locating a break in a cable or conductor by such measurement, the two balancing resistors of a Murray bridge circuit are replaced by a changeover switch S1, S2 with a variable switching time ratio. The bridge is balanced by altering the switching time ratio, and the switching time ratio is measured and displayed when the bridge is balanced. The polarity of a constant charging current which charges the capacitances to be measured is periodically reversed by switches 53, 54. Minor modifications of the circuit permit measurement and display of capacitance differences as well as of capacitances, after the insertion of standard capacitances. Unnecessarily large measuring voltages are avoided by such a method. <IMAGE>
Patent GB-2096372-A (GB)
Title: Logging a borehole while drilling
IPC: H01M50/251
Filed: 1978-12-04
Abstract: Pulses of pressure drop in the liquid (drilling mud) pumped to circulate in the boreholes are generated, in response to parameters sensed down the borehole, by rapidly opening and shutting a valve (36) in a comparatively wide bore passage which bypasses the drill head (26) or hydraulic motor which restricts mud flow in the borehole. A surface receiver in the high pressure side of the mud flow path is equipped with means to eliminate from the received signal the pressure variations arising from pulses due to the pump (12). The valve used to open or close the bypass is almost balanced by opposed pressure faces (50, 36) but is biassed by pressure bistably to its open or closed position such that only a very small driving force from drive means (54) is required to drive it from one to the other of these positions. <IMAGE>
