Abstract: 1302678 Minimising explosion risk in ships KONGSBERG VAPENFABRIKK AS 4 Oct 1971 [3 Oct 1970] 46127/71 Heading A5A [Also in Division Fl]  The invention relates to apparatus for supplying inert gas to holds or tank spaces in ships, the apparatus comprising a gas turbine engine the exhaust gases from which are passed to an afterburner in which the oxygen content of the gases is reduced, the gases then being passed through a cooler and thence to the holds or tanks, no blowers being required. The plant shown comprises a gas turbine engine comprising a compressor 1 combustion equipment 2 and turbine 3, the turbine driving the compressor also an electric generator 4. Fuel is supplied to the combustion chamber from tank 5 through pump 6. The turbine exhaust gases normally discharge through ducts 7 and 8 to atmosphere. When inert gases are to be supplied to a hold, a valve 11 in a duct 9 connected to the duct 7 is opened and the exhaust gases then pass to an afterburner 12 to which fuel is supplied from tank 5 through pump 15, line 14 and nozzle 13. The gases then pass to a cooler 16 into which sea-water is sprayed through line 17, the water discharging through outlet 19. The cooled gases then pass through the line 21 under control of valve 27 to the point of use. A pressure sensor 22 is connected to the line 21 and acts to control a valve 10 in the exhaust duct 8 whereby the pressure in the line 21 is maintained constant at say 16.4 psia. An oxygen analyser 24 is connected to the line 21 and acts on a fuel by-pass valve 25 so as to maintain the oxygen content of the inert gases within predetermined limits. When the inert gases are to be cleared from the hold air is taken from the compressor 1 through line 30 and passed to an ejector 31 which draws in atmospheric air, the air passing through duct 33 to the cooler 16 and then passing through line 21 to the point of use.

Abstract: 1344814 Detecting leaks H LUY 11 Oct 1972 [14 Oct 1971] 46955/72 Heading G1N Apparatus for detecting leaks in gas con-  tainers, e.g. aerosol cans, comprises hermetically closable chambers 13 in which the containers are placed and a device 14 which extracts a gas sample from each chamber in turn for analysis. The result of the analysis is stored at 26 and subsequently actuates a rejection device 30 if the container was faulty. The chambers 13 move the containers, optionally pre-heated, in a circular path between loading and unloading points 121, 122. After a container is loaded, its chamber is scavenged with air to remove unwanted gases, and then when the chamber reaches 14 a predetermined volume of gas is extracted by moving piston 16. Immediately before this extraction, valve 161 is briefly opened to allow air to enter and scavenge the gas detector 20. For aerosols the latter is a conventional Freon (R. T. M.) detector, and its output is amplified at 23 and passed via a threshold device 24 to store 26. When the container is removed from its chamber at 122 it passes to a photo-cell (not shown) adjacent rejector 30. This causes the store to be interrogated, and if the container was faulty the rejector 30 is actuated via encoder 27. Device 28 resets the store following rejection. A coder 25 controls the timing of the various valves and the threshold devices. Several detectors 20 may be used, and for greater sensitivity ionization detectors may be used, such as a flame ionization or electron capture detector or a spectroscope.

Abstract: 1,072,845. Electronic counters; shift registers. WESTERN ELECTRIC CO. Inc. Nov. 28, 1963 [Nov. 30, 1962], No. 47026/63. Headings G4A and G4C. [Also in Division H3] A binary counter or shift register includes a plurality of cores, each having a flux drive leg and an apertured cross leg, corresponding apertures of groups of the cores being coupled together by figure-of-eight closed loop windings for processing information, supplied by way of an input winding, through the counter or register to an output winding. In a counter a first core 10 differs from cores 11 to 15 (Fig. 1) whereas in a shift register all the cores are identical. The drive legs 20, and optional shunt legs 21, are coupled to windings 110, 111, 112 for successively driving pairs of cores to saturation in a clockwise direction and returning them to a condition in which the cross legs 22 are magnetically unsaturated. In the counter, before information is supplied, each winding 110, 111, 112 is energized in turn and coincident with energization of 111 and 112 a pulse is supplied to an initial condition winding 114 which threads all apertures 40 to 43 of cores 13 to 15. As the cross legs 22 of these cores are driven to their unsaturated condition anticlockwise fluxes are set up around the apertures. Simultaneously with the next energization of winding 110 information is supplied to input winding 48 from source 30. Energization of winding 110 meanwhile resets core 15 to its saturated condition and a pulse is induced in winding 52, indicative of the previous state of the counter (in this case " 0 " " as provided by winding 114). Windings 48 and 52 1  are so coupled to magnetic members 61 to 64 of core 10 that the currents therein assist switching of flux in only one of the magnetic members and as a result more flux is switched in this member (in this case 63) than in any other. Output signals are thereby induced in sum winding 50 1  and in carry winding 53 1  to switch flux around apertures 40 and 41 of core 11. Subsequent energization of windings 111 and 112 transmits the flux distribution by way of cores 12, 13 and 14 to core 15, which provides the previous state indication to be added to the next input digit by way of winding 52, and also a carry digit by way of winding 55 1  The carry digit is passed to the second stage of the counter which in due course supplies an output in winding 55 2  In the counter shown an output is produced in response to four input binary " 1 " digits. The number of stages may be increased by providing additional magnetic circuits similar to 60, 65 in core 10 and additional apertures in the other cores. One drive leg and associated shunt leg of each core may be omitted.

[Also in Division G3]  Underwater drilling apparatus for sinking casings 1, 2 and cementing them in place consists of a frame 3 connected to the casings and a drill and motor for each casing mounted on a box 8 which is detachable from the frame. The drills extend below the casings and have pivoted extending bits (Fig. 7 not shown) so that holes large enough for the casings are drilled while allowing the bits to be withdrawn upwards. When drilling is completed; cement is fed through a pipeline 13 to the casings. The. cement also moves a plunger 31 (Fig. 2) connected by a push rod 30 and .cables 28 to pins 27 which are withdrawn to release the drill motors 9, 10. and box 8 from the frame 3. Finally, a line 72 is pulled, withdrawing a pin connecting the pipeline 13 to the frame 3, to allow the pipeline to be raised. To preserve stability during drilling, there may be one or more hydraulic support legs 18. Drilling fluid supplied through a line 14 is distributed .to the drill motors and the support legs by a distributor 11 comprising a series of nozzles discharging against a plate which is kept horizontal by a universally mounted pendulum on which it is mounted. The pressure differentials across the respective nozzles vary according to the attitude of the frame, and are used to operate diaphragm controlled valves which control the fluid supply to the motors and/or support legs.

Abstract: 1,274,728. Combustion equipment for gas  turbine engines. ROLLS-ROYCE Ltd. Sept. 26, 1969, No.47564/69. Heading F1L. Combustion equipment comprises a combustion chamber having an interior of substantially circular cross-section, a substantially axiallyextending, centrally-located and permanently open gas outlet opening, and means for producing in the interior a combustible mixture swirling at a sufficiently high pressure and velocity to inhibit egress of said mixture through the opening until the velocity of swirl has decayed to a predetermined value. The combustion equipment is shown applied to a gas turbine plant which comprises compressor 11, combustion chamber 31, HP turbine 16, which drives a useful load 19, and an LP turbine 15 which drives the compressor 11. Air from the compressor passes to two lines 25, 26 and under control of rotary valve 29 to the main combustion chamber 31 and an auxiliary combustion chamber 30, respectively. Fuel is supplied to the main and auxiliary combustion chambers through inlets 39, 32 respectively and ignition means 40, 33 are provided in the chambers. Combustion gases from the auxiliary chamber pass through line 35 and inlet 36 to enter the main chamber tangentially. Air from the line 25 enters the chamber radially through inlet 37, the resulting combustion gases swirling within the chamber. The gases do not discharge through the permanently open outlet 38 which is disposed at the axis 34 of the chamber until the velocity of swirl has decayed to a predetermined value. Thus combustion occurs at constant volume. In place of the auxiliary combustion chamber 30, a piston and cylinder device may be utilized.

Abstract: 1283383 Semi-conductor devices GENERAL ELECTRIC CO 26 Sept 1969 [10 Oct 1968] 47576/69 Heading H1K The capacitance associated with PN-junction 20, 24 is greatly increased by the formation of an inversion region of controllable extent under capacitative electrode 17, 15A. Electrode layer 17 (with terminals 11/33 and 12/34) is resistive so that an increasing control potential applied to the electrode (12) nearest the PN junction leads to the formation of an inversion layer extending increasingly from the junction. A less-thaninverting voltage obtained from potentiometer 31 at the other end of this layer determines the value of the voltage at the junction end of the electrode at which inversion first occurs. That part only of electrode 17 is effective which lies on the thinner part 15A of the insulation 15. The shape of the control voltage-capacitance characteristic may therefore be tailored by suitably shaping the thinner area of insulation or by providing a shaped electrode 17 on part only of the thinner area (see Figs. 10 and 11, not shown). In embodiments the semi-conductor body is of silicon; the insulator layer 15, 15A is of silicon dioxide; the terminals 11, 12 are of molybdenum; the resistive layer 17 is of chromium nitride or of amorphous silicon; protective insulation 21 for the resistive layer is of silicon nitride; overlying insulation 18 is of phosphosilicate or borosilicate glass if the diffused zone 20 is formed near the end of the manufacture or is of undoped material if the junction is formed near the beginning of the manufacture; and terminal layers 25, (26), and 27 are of aluminium. The capacitor may be an individual device or may form part of an integrated circuit such as one containing IGFETs formed during common processing steps.

A bladed fluid torque transmitting wheel comprises separate inner and outer coaxial blade support members with a plurality of fixed blades secured therebetween by separable abutting surfaces. An outer semi-toroidal blade support member 44, which may have an integral hub 84 formed with driving splines or gear teeth 88, is formed with a number of conical axially-extending posts 56 which pass through hollow blades 48 and an inner semitoroidal support member 51. The blades are located by a circumferential ledge portion 58 of the member 44 and by tongues 78 engaging a groove 74 and are retained by deforming the end 66 of the post 56 against a washer 82 and the inner blade support. In modifications, the post 56 may be of other than circular cross-section and may be other than radial and parallel to the wheel axis. The blades may be of sheet metal or formed to blade configuration by casting or moulding and may be hollow or be shaped to fit the particular form of post. The blades and support members may be of steel, cast iron, light alloy or plastic and may be moulded or stamped to shape. In a further modification, an outer shell 174, Fig. 13, is welded to the outer blade support 170 and has stamped out posts 182 passing through apertures in the members 170 and 198. The blades may be located by a ring 210 secured to the outer support and the assembly may be held together by a circumferential split ring engaging notches in the ends of the posts 182 and bearing on the inner support 198.

Abstract: 1,077,829. Automatic position control. J. G. HENDERSON. Nov. 24, 1964 [Nov.26, 1963], No. 47687/64. Heading G3R. In an edge guiding system for sheet material, an edge feeler operates a switch on deviation of the edge from a predetermined position so that a controller including a particular arrangement of electronic valves, relays and time delay device restores the edge to the predetermined position. In Fig. 1, fabric 10 having a pile 11 and a selvage 12 is supported on a driven feed roll 15. Before starting feed roll 15, a handwheel 43 is operated to move a detector 30 into the position shown so that pairs of cam-shaped feelers 31, 32, 33, 34, rotatable on a shaft 35, ride on the pile and selvage respectively in the manner shown. During operation, if the fabric moves laterally in one direction or the other, the relative movement of feelers 31, 32 or 33, 34 actuates associated switches to operate thermionic valve relays 28 and cause an electric motor 25 to run in the appropriate direction to restore the fabric to the position shown by lateral movement of roll 15. Additional switches associated with the feelers ensure appropriate operation of motor 25 even if the lateral deviation is such that all the feelers ride on the pile or selvage. The position of roll 15 may alternatively be controlled through a fluid-pressure actuator. Thermionic valve relays 28 include adjustable resistancecapacity delay networks to prevent operation of motor 25 as the result of occasional edge imperfections.

A parachute pack 1 is connected by a static line 12, 6 to an anchorage 10 on the aircraft, a part 4b of a releasable fastening being fixed at an intermediate point on the static line for attachment to the rest 4a of the fastening fixed to the parachute harness. When the fastening is connected, the part 6 of the line acts as a safety line and can be lengthened for increased mobility. The part 12 of the line, between the fastening and the top 9 of the pack has a surplus length to prevent accidental deployment and also is attached to the harness by a press-stud 12. The parachute is deployed by releasing the fastening by turning a button 14, and falling through the doorway 13. The force required to turn the button is sufficiently small for it to be operated when the wearer has fallen from the aircraft and is hanging on the part 6 of the line.

Abstract: 1408227 Punched tape reader SIEMENS AG 12 Oct 1973 [16 Oct 1972] 47707/73 Heading G4M  A reader for punched tape containing sprocket holes for producing clock pulses has two sprocket hole detectors spaced by a distance equal to the distance between sprocket hole centres plus half the diameter of a single sprocket hole (Figs. 3, 4 not shown). The two detectors produce signals Ta, Tb respectively during movement of the tape. The graph of Fig. 5 shows tape movement from a rest position to a read position 24 where tape bounce occurs to a further read position 36 and then reversal of tape movement. Ta and Tb are '1' when their detectors coincide fully with a sprocket hole and change state when they are shifted half a sprocket hole diameter from this position. The clock pulses Ta, Tb are fed to a circuit (Fig. 6) which feeds a clock pulse T to enable bistables 42-49 to receive data from the punched tape. Ta and Tb are fed directly or via inverters 55, 54 to bistables 50-53 where a '1' on the a input sets the bistable if the b input has a transition from '0' to '1'. Thus at tl (Fig. 5) bistables 51 and 53 are enabled and 51 and 52 have '1' inputs so 51 is set. At t3 bistable 50 is set so AND gate 56 is enabled and pulse T1 is produced from OR gate G0, and via delay 62 resets the bistables. At t5 51 is set, at t6 52 is set and reset pulse R2 is produced from delay 62. At t8, 69, 53 and 50 are set to produce R3. At t10 51 is set and at tll 50 is set producing T2 and R4. At t12 53 is set and at t13 52 is set producing T3 and R5. For a timing pulse T to be produced a '1' to '0' transition of Tb occurs after a '1' to '0' and before a '0' to '1' transition of Ta. This indicates consecutive movements of the tape in one direction with no oscillation.

Abstract: 1408613 Controlling suspension height HOESCH AG 17 Oct 1972 [22 Oct 1971 22 June 1972] 47830/72 Heading B7D [Also in Division F2] In a vehicle suspension system, one unit 49 (see Division F2 for more details) has an internal level regulating device comprising two valve members 31, 45 which co-operate with one another for controlling liquid flow between the working chamber and a connection 41 (to a source and drain, not shown) to effect upward and downward regulation, and this unit controls another unit 50 on the other side of the vehicle. In Fig. 6 (not shown) the unit 50 has no levelling valves and so its upward and downward regulating is controlled by the unit 49, a pipe (55) interconnecting the working chambers of both units. In Fig. 5, downward regulation is effected separately for the units 49, 50 but upward regulation is controlled by the unit 49. The operation of the unit 49 is as follows when the static load on the vehicle increases so that the suspension unit is contracted to below its means length (as shown), the valve member 31 is held on to its seat by a tension spring and so forces the valve member 45 off its seat against spring bias. An electric motor driven pump (not shown) is actuated in response to the change in height and causes liquid from the source to enter the working chamber via the opened valve member 45, the valve stem 46 and the valve member 47, which lifts off its seat, to expand the unit and raise the vehicle. When the mean length is reached, the valve member 31 is entrained by the piston, and lifted off its seat, enabling the valve member 45 to close and cut off the supply of liquid to the chamber. When the static load on the vehicle decreases so that the suspension unit extends beyond its mean length an electromagnetic valve (not shown) in the pipe 41 opens to allow the pressure in the pipe to fall, so that the valve member 45 opens in response to the pressure in the working chamber and liquid flows out, contracting the unit and lowering the vehicle until valve member 31 seats again, closing the entrance to the valve stem 46.
