Patent GB-2067663-A (GB)
Title: Safety Device for a Diesel Engine Equipped with a Supercharger
IPC: F02D1/08
Filed: 1981-01-13
Abstract: A safety device is fitted to a control device (1) which operates in dependence upon charging pressure and which, by means of a wall (8) movable by the charging pressure (pL), acts upon a delivery quantity adjusting member (6) of a fuel injection pump in a direction to increase the delivery quantity. In the event of an inadmissibly high charging pressure (pL), an electromagnetic control member (19) controlled by an electronic control device (20) directly or indirectly returns the movable wall (8) into a position in which the delivery quantity adjusting member (6) establishes a reduced delivery quantity. The member (19) may be a solenoid valve which modifies the pressure acting on the wall (8) or a lever operated by a solenoid. <IMAGE>
Patent GB-2070793-A (GB)
Title: Electronic flash apparatus
IPC: G03B15/05
Filed: 1981-02-26
Abstract: A flashtube (18) is quenched when a light-responsive integrating circuit 15 has received a required amount of light; said amount being reduced if the ambient light exceeds a certain level. As shown, a light-level sensing circuit (14) measures the intensity of the ambient light. A threshold-setting circuit (22, 32, 34), responsive to the sensing circuit (14) causes the amount of light needed to be sensed by the integrating circuit (15) for terminating the flash in bright ambient light to be less than the amount of light required to be sensed for terminating the flash in low ambient light. Alternatively, the integrating circuit has two capacitors, one of which is switched out when ambient light is bright. A single element may be used to sense both the ambient light and the flash light. <IMAGE>

Title: A machine for building wafer sandwiches
IPC: A21C15/02
Filed: 1981-09-04
Abstract: A machine for building wafer sandwiches comprising a building unit (12) to which individual wafer sheets are successively fed from an input conveyor (10) and which causes the wafer sheets to be stacked in super- imposed relationship to produce a wafer sandwich which is subsequently removed from the building unit by an output conveyor (11). In the building unit (12) the individual wafer sheets are received by a pair of contra-rotating part-circular shelves (14) which convey the sheets forwardly against a stop (21), and, after a degree of rotation, deposit the sheets successively onto a plurality of rails (51) which support the sheets until the sandwich is completed, whereupon the rails (51) are lowered on pivotted arms (52) so that the sandwich is deposited onto the output conveyor (11). The shelves (14) are rotated continuously or intermittently to ensure substantially continuous operation. Alternatively, a second pair of intermittently contra-rotating, part-circular shelves may replace the rails or rails and second pair of shelves may be omitted if conveyor (11) is stationary during stacking. <IMAGE>

Patent GB-2097805-A (GB)
Title: Soft contact lenses and manufacture thereof
IPC: B29D11/02
Filed: 1982-04-27
Abstract: Soft contact lenses are made by polymerizing a substantially anhydrous polymerization mixture containing a polymerizable acrylic or methacrylic monomer, and a water displaceable ester of boric acid and a compound containing 3 or more hydroxyl groups so as to form a hydrophilic polymer containing at least 30% of said boric acid ester. In a preferred embodiment, the polymerization is effected in a mould cavity where the contact between a sharp circular edge in one mould part and a spherical surface in the other mould part defines the edge of the lens and the distance between the two mould surfaces outside the sharp edge increases in all radial directions away from the center. The boric acid ester is displaced from the hydrophilic gel polymer by water on a 1:1 volume basis and thus the water content in the final lens can be closely controlled. The procedure also permits the production of lenses which have the same shape and size as the mould cavity in which they were polymerized. <IMAGE>

IPC: G06V10/10
Filed: 1982-11-02
Abstract: Processing of information obtained at a high rate is carried out in parallel to enable presentation of such information substantially in real time. Digital electronic circuit means is adapted to receive and process information from a linear array of photo diodes scanning a succession of objects and producing a raster of given width but of indefinitely extended length. The information is fed to the processor serially by a multiplexer 32 and likewise is output serially by a demultiplexer 62. Processing of information derived from any given scan, or by comparison of scans stored in a memory, is carried out in a parallel manner by interconnected circuits 40/1 to 40/n in order to provide speed of operation. Principal uses are in the inspection of objects carried past a said array of diodes; and in processing satellite photographs, and images resulting from medical X-ray and ultrasound scans. <IMAGE>

Title: Centrifugal oil weirs
Inventor: WINDLE DONALD OMER
IPC: F16C33/66
Filed: 1983-05-31
Abstract: A centrifugal oil weir 98 transfers lubricating oil between, e.g. a rotating shaft 36 and an oil catcher ring 102 which is also rotating, but at a different speed from shaft 36. Normally, oil, held in chambers 94 between weir 98 and shaft 36 by centrifugal force, enters flow channels 108 in the weir surface 112 via inflow edge 110 and is centrifugally dispensed to catcher ring 102 via outflow edge 114 and oil flinger lip 115. There is also normally an axial clearance between lip 115 and a bearing race (Figure 2) with which catcher ring 102 is associated, but in the event of this clearance being reduced sufficiently to cause blockage of the outflow edge 114, that oil which would normally be dispensed from the outflow edge is dispensed instead from apertures in the form of scallops 106 in the outflow edge. In this way, the supply of oil to the bearing is maintained. <IMAGE>
