Abstract: 626,053. Photographic silver salt emulsions. KODAK, Ltd., TEAL, E. F., and DAVEY, E. P. April 1, 1946, No. 10022. [Class 98 (ii)] A developing-out silver salt emulsion is prepared by forming the sensitive silver salt in the presence of one or more of the following substances: arsenites (e.g. meta-arsenites), stannites, phosphites (e.g. meta- and hypophosphites), antimonites, hyposulphites and germanites. The emulsion may be of the ammoniacal or non-ammoniacal type, and may be a silver bromiodide or bromide emulsion. The emulsion may be coated immediately after ripening without washing, or may be washed and digested before coating. The emulsion may be an autopositive emulsion which is chemically fogged (e.g. with hydrazine, formaldehyde, hydroxylamine, or excess silver nitrate, or by extra digestion with or without sulphur sensitizers such as sodium thiosulphate), or light fogged. The substance may be added to the mixed halide solution used for forming the silver bromiodide emulsion, and the emulsion made in the usual manner using ammoniacal silver nitrate solution. With an autopositive emulsion, the formation of negative images on low exposure may be avoided by adding hydrazine hydrochloride or formaldehyde to the emulsion immediately after mixing the two solutions. The emulsion may be sensitized with sensitizing dyes, and a quantity of dye greater than the optimum may be used as in Specification 524,087. A developing agent such as hydroquinone may be added to the emulsion to permit of development merely by immersion in alkali, and the emulsion will thus be tanned imagewise, permitting the unhardened parts to be washed off.

Abstract: 1,217,841. Digital computers; simulators. FERRANTI Ltd. 11 March, 1968 [8 March, 1967], No. 10799/67. Heading G4A. A field selection system for selecting any desired one of a plurality of fields which together comprise one word of a computer code and comprising word storage means, word defining register means and selection means enables a computer to operate with different machine codes. As shown (Fig. 2), 24-bit machine code words (external orders) are read from a main store into a register w. Registers # 0  and # 1  (Fig. 3) contain information in the form of patterns of 1's and 0's defining the field breakdown of the relevant machine code. Masking gates 10 (Fig. 7, not shown) enable a selected field from the register w to be transferred to a predetermined position in a register #. By varying the contents of registers # 0  and # 1 , different machine codes can be processed. If only a restricted number of machine codes are to be catered for, the masking registers # 0  and # 1  may be reduced in length, each bit of these registers then representing a zone of bits of the register w (Figs. 9-12, not shown). Further simplification may be achieved with single bits representing selected zones. The figures referred to above relate to a simple hypothetical computer. Three other embodiments of more sophisticated computers are described in detail with reference to Figs. 13-92 (not shown), all of which computers are for processing 24-bit words in parallel, each word having associated with it 2 or 3 extra bits defining the type of word. NOR and OR logic is used. The computers also involve the use of external orders (microinstructions) the function field of which defines one or more internal orders (micro-instructions) stored in the same memory. Interrupt instructions, indirect addressing, external orders in the form of internal orders (equivalent forms), double length working, an adder circuit (Figs. 25 and 61, not shown) and fast carry propagation (Figs. 16-24 and Fig. 61, not shown) are described. The following modifications are referred to: the logic may comprise NAND and AND gates, the words may comprise other than 24 bits, the computer may operate in the serial mode.

Abstract: 724,004. Gas-turbine jetpropulsion plant. ROLLSROYCE, Ltd. April 9, 1953 [April 29, 1952], No. 10812/52. Class 110 (3). A gas-turbine jet-propulsion engine' has a reheat chamber before the propulsion nozzle to which fuel is fed by an air turbine-driven fuel pump, the turbine of which is fed with air tapped off from the compressor and which exhausts to atmosphere through a restriction whereby the pressure ratio across the air turbine is less than the ratio of the inlet pressure of the air turbine to atmospheric pressure. Air from the compressor 10 is fed to the combustion equipment 11 which supplies combustion gas to the turbine 14 driving the compressor. The turbine 14 exhausts to the atmosphere through a jet pipe 18 and variable area propelling nozzle 19a. Under normal conditions fuel is supplied to the combustion equipment 11 from a tank 12 by pumps 12a, 15 and is controlled by a throttle 13. When additional thrust is required fuel is supplied to the main burners 20 in the jet pipe 18 by a fuel pump 26 driven by an air turbine 27. The main burners are ignited by a pilot burner 21 supplied with fuel by the pump 15. The air turbine 27 is supplied with air by the compressor 10 through a conduit 28 and throttle valve 29. To avoid an excessive run-away speed of the air turbine 27 the pressure ratio across the turbine is limited. In the arrangement shown, the air turbine exhaust conduit 30 is connected to the jet pipe 18 so that the exhaust air passes through the propelling nozzle 19. When the reheat system is in operation, the propelling nozzle 19 is usually choked so that the pressure drop across the air turbine is less than if the turbine exhausted to atmosphere so that the run-away speed is limited. In another arrangement, the conduit 30 is connected to a manifold encircling the jet pipe having nozzles which induce cooling air from the atmosphere into a casing surrounding the jet pipe and then through hollow variable area nozzle segments. To cool the jet pipe when the reheat is out of operation, a bypass pipe containing a restrictor may be provided around the turbine. The flow may be diverted through either the turbine or bypass pipe by a two-way valve. The air turbine 27 is preferably a two-stage pressure-compounded impulse turbine, that is, one in which part of the expansion takes place in the first stage stationary nozzles and the remainder in the second stage stationary nozzles. Specifications 608,963 and 667,394 are referred to.

In a method of casting comprising the steps of positioning a tube 18 with its lower end immersed in a bath of molten metal 26 within a sealed chamber 35 and positioning a mould 2 with its gate 14 communicating with the tube, sub-stmospheric pressure is developed in the chamber to lower the metal in the tube to approximately the bottom thereof, and then super-atomospheric pressure is developed in the chamber to urge the metal through the tube into the mould, the flow of metal to the mould being terminated when the mould is filled by moving a plunger valve 42 against the gate to close same. The tube is inclined to the vertical and its lower end may be closed by a fusible cap to prevent the entry of slag when entering the molten metal reservoir. A riser 12 is positioned at the highest point of the mould cavity, and the distance between the plungerseat 44 and the gate-seat 46 is substantially less than the distance between the plunger-seat and the upper surface 48 of the hub section of the mould cavity, to reduce pumping action of the plunger on the metal in the mould. In other respects the mould and chamber are substantially as described in the parent Specification.
