IPC: F41F3/08
Filed: 1939-06-07
Abstract: 581,882. Firing torpedoes. PAINE, H. SCOTT-, and GWILLIAM, V. C. E. MARTEN-. June 7, 1939, No. 16748. [Classes 9 (ii) and 92 (ii)] Consists of a remotely-controlled percussion firing-mechanism for torpedoes. The combustion chamber 10 of the torpedo-tube houses a cartridge 12 and to the breech-block 11 is fixed a casing 13 housing a striker 14. The striker may be withdrawn manually against the action of the spring 16 and if desired locked in the retracted position by means of a pin 18 engaging within a bayonet-slot 19. At the forward end 15 of the striker is a bevelled edge 20 engaged by a sear 21 pivoted at 23 and normally held against the'striker by a triggerlever 24 pivoted at 25. When the lever is moved against its spring 31 by a Bowden cable 32, the nose 28 of the sear is forced laterally by the striker into a notch 27 in the lever. When the striker is again retracted by means of a handle 17, a cam surface 29 in the striker stem acts on the end 30 of the sear lever so that the sear is again moved to engage the nose of the striker. The mechanism is lubricated from an oil cup 33. The Bowden-wire casing passes through: a spherical oil-tight joint at its entry into the casing 13. The mechanism may be used with the torpedo-holding and firing devices described in Specifications 581,880 and 581,881.

Filed: 1962-05-02
Abstract: 940,054. Electric selective signalling systems. JERVIS B. WEBB CO. May 2, 1962, No. 16781/62. Drawings to Specification. Heading G4H. The invention provides an apparatus for detecting the arrival of a carrier, for example, of a conveyer of the floor track type - at a certain position and for producing a control signal upon such arrival. The carrier is provided with a non-energized resonant pick-up circuit which, when the carrier is at the selected position, lies directly above an energized coil detector. The resultant coupling between the pick-up and the detector causes the detector to produce a control signal. To increase the number of different arrival points, the resonant frequency of the pick-up and detector is variable, and the position of these units relative to the track is also variable. Further, more than one detector may be required to detect the presence of a pick-up before a control signal is produced. Such detection may be simultaneous or sequential.

Abstract: 706,129. Conditioning exhaust gas. ALCOCK, J. F. May 28, 1952 [July 19, 1951], No. 17187/51. Class 7(2) In an engine exhaust gas conditioning means comprising a conditioning water tank f, an auxiliary water tank c and an ejector c arranged in the exhaust pipe a, the ejector c is arranged to draw water from the auxiliary tank e and is of such dimensions that it will not detrimentally impede the normal flow of gases through the pipe a, the ejector becoming operative when the gases attain a temperature and hence velocity corresponding to a given engine load condition. Within the pipe a is located the Venturi ejector c to the throat of which latter is connected a conduit d from the auxiliary tank e, the water thus induced is evaporated by the exhaust gases and is subsequently condensed in the tank f where it serves to replenish evaporation losses. The tank e which is usually located below the level of pipe a may either be closed or open to atmosphere; in the former case a conduit g joins the top of the tank to the pipe a so that the exhaust gas pressure assists the displacement of water therefrom. The Venturi may be replaced by a nozzle.

Abstract: 778,957. Starting prime movers; electric supply systems. LISTER & CO., Ltd., R. A. June 10, 1955 [June 11, 1954], No. 17273/54. Drawings to Specification. Class 38 (4). A compression-ignition engine, particularly one for driving the generator of automatic electric power supply plant which starts up on closure of the load circuit, has an electrically operated starter motor (which may, in fact, be the generator) and an associated battery, there being also an electric switch-motor which is started when it is desired to start the engine and which drives a series of cams for controlling the sequence of operations necessary in starting the engine, some of the cams operating switch contacts and others directly controlling through mechanical linkages the fuel pump and engine decompressor, and the arrangement being such that once the switch motor has been started the complete starting cycle 'of operations is carried out, even if stopping of the engine is attempted before it becomes self-running. The motor-driven cam switches may also be arranged to effect a complete cycle of stopping operations when the engine is to be stopped, so as to be left in readiness for restarting the engine. The current supply to the switch motor is controlled by switch mechanism actuated by a cam driven by the motor, the mechanism comprising two detents each arranged by its movement to actuate a respective current supply switch in the motor supply circuit, the two switches being in series and the detents being on diametrically opposite sides of the cam and engaging alternately in a notch in the edge of the cam to break the current supply, and the appropriate detent being disengaged from the notch on initiation of a starting, or stopping, cycle. When the engine drives an electric generator, a circuit breaker actuated by one of the cams may open the battery-starter motor circuit if the generator fails to excite. In the case of stopping cycle which includes the actuation of a decompressor for the engine, means responsive to engine oil pressure may prevent each actuation until the pressure falls below a selected value.

[Also in Division F2] A trolley 27 is driven by a member 24 engaging a pin 26 extending through a slot 20 in the floor; the pin sliding in fixed bearings 30, 31, can be raised out of the slot 20 by raising handle 32 which can be engaged in notch 33 in bracket 34 or can be raised away from member 24 by rearward movement of bumper 38 on striking another trolley 36 so causing rollers 51 carried by a sleeve 50 of pin 26 to move up cams 46 on arms 44 to engage sleeve 50 with a collar 52 on the pin. To enable a trolley 18 to push another trolley 17 into an undriven spur line 12, a cam 76 is placed just before a switch point to rotate a lever 60, through roller 72, lever 70 and shaft 62, to the full-line position, Fig. 3, in which a member 66 extending between members 44 engages in a notch 64 in lever 60 to stop rearward movement of the bumper 38 and the raising of the pin 26. The cam 76 is discontinued at the switch, Fig. 5, to allow a trolley 17 to pass to the spur line 12, but a catch 78 in notch 64 prevents disengagement of member 66 from lever 60, the trolley 18 thus continues to push trolley 17 into line 12. A further cam 84 raises roller 72 to cause disengagement of the member 66 from the notch and a spring 54 acting on a spacer 58 between arms 44 returning the bumper to its normal position. To prevent a trolley running back when the drive is disconnected, the rearward movement of arms 44 moves a rod 97, connected to spacer 58, the rod passing freely through a slot in lever 96 to allow a plate 99 to descend to move a lever 96 against a rubber-tyred wheel 101, any backward movement causing lever 96 to dig into the tyre. The front and rear bumpers of each trolley have circular arc profiles with the pin 26 as an approximate centre for each arc, the rear bumper 36 having a flange 87, Fig. 1, to prevent the front of a pushing trolley from rising.
