Filed: 1961-02-07
Abstract: 933,570. Torpedoes. THOMPSON RAMO WOOLDRIDGE Inc. Feb. 7, 1961, No. 4578/61. Class 9 (2). [Also in Groups XIII and XXVI] Fluid is vaporized in a container by the heat of fusion of a molten fusible material and the vapour thus formed drives a turbine, the spent vapour being condensed and the eondensate being returned to the container. A submarine torpedo 12, having a warhead, a guidance system and a sonar system (not shown), contains a boiler 18 which has three groups 40, 42, 44 of cylindrical cartridges each containing lithium hydride or other heat storage material such as aluminium or sodium chloride, and each having a coaxial electrical heater element 49 connected by a connector 62 and a cable 64 to a plug 61 which may, at will, be connected with the submarine generator system so that the lithium hydride becomes molten and thereby provides a heat store. The boiler 18 is covered at 50 with a heat-insulating material such as a material known under the Registered Trade Mark " Thermoflex," so that once the lithium hydride is molten only a small supply of power (about 6 kilowatts) is required to replace heat losses while the torpedo is awaiting use. The cartridges are clad with niobium or stainless steel to reduce corrosion. A pressurized tank 20 stores water which upon the launching of the torpedo is passed into the boiler 18 through a valve 34 to be initially heated by the group of cartridges 40 and changed to saturated steam by the group 42, which steam is superheated by the group 44 which has a high surface to weight ratio. The steam is fed to a turbine 22 which drives contrarotating propellers 14, 16 through a reduction gear-box 30. The exhaust from the turbine passes to a condenser preferably having tubes such as 54 cooled by sea water entering openings 59, the condensate being fed through a conduit 60, as by a pump 65 driven through the gear-box 30 or otherwise, back to the boiler 18. Instead of steam the working fluid may be a fluid known under the Registered Trade Mark " Dowtherm " or it may be mercury vapour. In the latter case, the reduction gear-box 30 may be omitted and a directly driven propeller used.

Title: Improvements in or relating to Devices for Producing Axial Displacement of the Shafts of Rotary Converters and other Apparatus.
Inventor: FIELD ALLAN BERTRAM
IPC: H02K5/167
Filed: 1917-04-02
Abstract: 114,468. Field, A. B. April 2, 1917. Reciprocating shafts axially.-Limited axial movement is imparted to the rotating shaft of an electrical rotary converter by fluid pressure. Oil in a chamber E<1> under pressure, which may be that generated by rotation of the shaft A, enters at each revolution a radial passage C in the shaft, fitted with a ball valve C<1>. The pressure acts upon a fixed plunger B and moves the shaft to the right until the accumulated pressure is sufficient to force back a spring-loaded plunger N acting on a ball valve K, when the oil escapes through a restricted passage L and the shaft returns to its original position. A tube F in the chamber E<1> forms an air chamber to maintain the pressure. or a compressible closed hollow steel capsule may be placed in the chamber for this purpose. The oil enters the passage B<1> in the plunger B through an annular opening J<1> around the edge of a plate J; this ensures that oil, which is kept by centrifugal action against the walls of the cylinder A'. shall enter the passage B<1> rather than air.

Title: Improvements in or relating to photographic shutters
IPC: G03B9/22
Filed: 1945-02-26
Abstract: 585,691. Photographic shutters. TAYLOR, TAYLOR, & HOBSON, Ltd., and CLIFFORD, T. W. Feb. 26, 1945, No. 4798. [Class 98 (i)] In a pivoted blade symmetrical opening shutter, each pivot pin constitutes the pivot of a set of superimposed blades whose operating studs lie at different distances from the pivot pin so that upon operation of the blade-operating member the blades of each set move respectively through different distances. For an increasing number of blades in each set, the slots have to be correspondingly larger. The front body of the shutter assembly carries a fixed blade pivot ring with pivot pins E<4>, and a blade-operating ring, F carrying studs F<1>, F<2> is angularly adjustable thereon. The blades are in pairs E<1>, E2, the studs F<1>, F<2> being offset and lying at different radial distances from the main axis O. The stud F<1> extends through an elongated slot F<3> of the lower blade E<1> and through an opening F<4> in the upper blade E<2>. The second stud F<2> extends through different parts of the openings F<3>, F<4>, which are so shaped (roughly L-shaped) that pivotal movement of one blade does not interfere with that of the other blade. In the fully-open position of the shutter, the two sets of blades are superimposed so that the annular space accommodating the blades is roughly equal to their width. Movement of the ring F swings the lower blade E<1> further than the other blade E<2>, and the two blades cover different areas of the aperture. Widening and/or thickening of the blades E<1>, E<2> at their pivot ends enables the pivot pins E<4> to be positioned to engage the blades at or near their centres of gravity. Specification 585,690 is referred to.
