Abstract: 972,033. Semi-conductor devices. SIEMENSSCHUCKERTWERKE A.G. Oct. 31, 1962 [Oct. 31, 1961], No. 41274/62. Heading H1K. A plurality of rectifier elements are simultaneously manufactured by applying a layer of semi-conductor material to a carrier plate, applying a plurality of small counter-electrodes using a mask, covering with lacquer, applying a continuous collecting electrode which penetrates the lacquer to contact the counterelectrodes, thermally and/or electrically forming, and then dividing the assembly to form a plurality of separate rectifier elements. As shown, an aluminium carrier plate 1a is covered with a selenium layer 1b formed by evaporation, on which are deposited counter-electrodes 4 of a eutectic tin-cadium alloy by spraying or evaporating through a mask. The exposed surfaces of the selenium and the counterelectrodes are covered with a heat resistant silicone lacquer 5 which is allowed to dry. A collecting electrode 6 of tin alloy is sprayed on to the lacquer and penetrates the surface to make contact with the counter-electrodes 4. The assembly may then be heated to crystallize the selenium layer and to alloy the counterelectrodes to the collecting electrode, the porous structure of the sprayed-on collecting electrode allowing gases given off by the lacquer to escape. The assembly may then be electroformed and is finally divided by stamping into individual rectifier elements each containing one counter electrode. In a modification, the counter-electrodes are applied in strips across the selenium layer.

Abstract: 1374838 Apparatus for connecting submerged pipes; cleaning with fluid jet SUBSEA EQUIPMENT ASSOCIATES Ltd 6 Sept 1972 [10 April 1972] 41308/72 Heading F2G and F2N Apparatus for connecting a pipe 32 by remote control between submerged terminal stations, each having a conduit 15 and a guide structure 35 therearound, includes a mobile support 40 carrying connectors 11, 7 linked by the pipe 32. The connectors 11, 7 are held in the support 40 by retaining means 41, 58 and 13, 12 which are released in turn at each terminal station by contact with a stop member 14 on the guide structure. The connectors lock on to the conduit end 15 by depression of a connector control member 11d (see Specification 1,374,712 this Division). After connection of the lower connector 11 to the conduit 15 the support 40 is movable to a second terminal station and connector 7 is connected to a conduit (38) (Figs. 2, 3 not shown), inside a guide structure (37) thus connecting the conduits by the pipe 32. As shown, the support 40 is lowered from the surface on a rod string 33 provided with impact absorption devices both on the surface vessel and at 23, 24, and guided to the terminal by a locating device 10, e.g. sonar equipment, the pipe being held clear of the support by floats 28, 29 connected by frangible painters 47, 48 to a support 30. As the support 40 is lowered into the guide structure 35 a feeler 19 contacts a stud 52 and triggers the release of a first stop 25, Fig. 1b to release a rod 22 and thus also the support structure 40. The support 40 drops causing the stop 14, Fig. 1a, to lift a sleeve 13 which frees locking ball 41. An abutment 9 on a sleeve 18 depresses the connector control member 11d to lock the connector on to a flange 15a of the conduit 15. During this lowering, a lever 56, Fig. 1a, controlling the tap 4a of a compressed air bottle 2, strikes a stop 57 to open the tap. Compressed air is delivered through a tube 16 when the end of the tube is adjacent the flange 15a. The eddies of water so formed remove marine fouling on the flange 15a to ensure a good connection. The support is then raised and moved to the second terminal where the operation is repeated with the upper connector 7, a second stop 26 initiating the fall of support 40, release of locking ball 58, opening of a tap 4b and depression of the connector lock control 7b by a plate 34. As the rod string 33 is finally raised, frangible painters 47, 48 break since the floats 28, 29 are connected to rod 33 by lines 49, 50.

Abstract: 1529715 Electro-chemical analysis: measuring impedance ratio BACTOMATIC Inc 14 Oct 1975 [15 Oct 1974] 42015/75 Headings G1N and G1U The real part of the ratio of a first impedance 12S, Fig. 1, to the sum of the first impedance and a second impedance 12R, is determined digitally by arranging the two impedances in a bridge, as shown, together with a ladder network, and automatically adjusting the ladder until the real part of, that is the part in phase with an A.C. power source 16, of the diagonal voltage is reduced to zero. As described the first impedance 12S is that of a sample of an unknown micro-biological organism growing in a particular nutrient medium, and the second 12R is that of a reference organism. According to the Specification, the way in which the impedance ratio evolves in time is of assistance in identifying the unknown organism, and to this end the impedance ratio is converted from digital form to analogue form and plotted, together with the ratios for other cell pairs, by a graphical recorder Fig. 3 (not shown). In the preferred embodiment, the voltage, 92, Fig. 4, from the junction of the two impedances 12S, 12R is applied to a differential amplifier 90 together with the output voltage from an R-2R resistor ladder 36. The amplifier 90 output, is phase-conscious rectified, 94, smoothed 98 and applied to the automatic balancing control circuit, in which, in operation, the stages of the ladder are successively turned on via solenoids 80 by shifting a one-bit down a register 56, 58 and those stages which overbalance the bridge are immediately turned off by the output from the comparator. Thus, at the end of a cycle of operation J-K triggers 76, controlling the solenoids, store in pure binary, the required real part of the impedance ratio being measured. The measuring equipment may be used with a plurality of pairs of impedances using conventional multiplexing techniques.

The heat pipe comprises means 11 to remove excess of the vapour phase of the heat transfer fluid from the heat pipe and means 8, 9, 9b to supply to the heat pipe make-up heat transfer fluid in the liquid phase. The excess vapour removed is condensed and may pass into the engine or gas turbine cooling system (radiator 13) from which the make-up liquid is supplied. Liquid can also pass from the heat pipe 1 via non-return valve 21 to the cooling system, which may be a sealed radiator system. The heat transfer fluid may consist of a mixture of water and an alcohol, e.g. methanol or ethylene glycol with at least 50% by weight water. A valve 18 allows air to enter the heat pipe on cooling. To control heat supply to the heat pipe, the amount of exhaust gases 16 passing through conduit 5 is variable by a diverter valve in the exhaust system which may be responsive to pressure in the heat pipe, the position of the engine throttle valve or exhaust gas temperature. Additional cooling means may be present in the heat pipe. A compressor may be present in the engine inlet system upstream or downstream of the point at which air and fuel are mixed. Water or steam may be injected into the cylinders. Additional heating means, e.g. an electric heater, may be provided for vaporizing fuel during a cold start and may heat the fuel or all or part of the fluid in the heat pipe.
