Title: Marine propulsion unit
IPC: B63H11/14
Filed: 1970-04-22
Abstract: 1357322 Propelling ships R GRAY 21 July 1971 [22 April 1970] 19344/70 Heading B7V A ship is propelled by using steam pressure to expel water from a container in the ship through a jet pod located below the ship. As illustrated in Fig. 1, three containers 1, 2, 3 are discharged and refilled in sequence to provide a continuous pulsating jet from a jet pod 10 to which they are connected by lines 11. Water is tapped from the discharge line of whichever container is discharging at any particular time and passes through a one-way valve 6 and a preheater coil 5 into a flash boiler 7 from which steam passes to the head of the  next container in the cycle to discharge it. The cycle is commenced by means of a pump 4. Steam enters the containers through ejectors 9 to draw in seawater through a line connected to the forward end of the jet pod. The effective water capacity of the containers is thus increased. The containers refill by gravity, the refill water entering the containers through ejectors in their discharge lines. The pressure build-up at the forward end of the jet pod may be used to speed up the refilling process. In the embodiment illustrated in Fig. 3, the containers 104, 105 and 106 are supplied with steam from a single boiler 101. The containers discharge cyclically, the discharge of one container initiating the supply of steam to another. At a typical point in the cycle container 105 discharges and its discharge pressure opens a valve 107 to allow passage of steam from a header 103 to an orifice plate located between valve 107 and a closed valve 108. When steam pressure equalizes across the plate, valve 108 opens to admit steam to container 106 to discharge it and thereby to continue the cycle. Steam passing to the containers entrains boiler furnace flue gases at ejectors 109. In contrast to the Fig. 1 embodiment, steam is generated from a demineralized feedwater supply. The feedwater is fed to the boiler by pulses of steam from one of the valves 108 acting on the surface of water in a vessel 116. Feedwater passes through a one-way valve, a regulating valve and a preheating coil to the boiler. Any excess feedwater enters a vessel 115 to compress air in it and thereby to maintain the feedwater supply pressure. The containers 104-106 are refilled with seawater through the suction openings of ejectors 11. The containers, jet pod, and steam generating equipment are mounted as a unit in a through wall of the ship. The unit can be turned to change the direction of pod thrust and can be raised and lowered to position the containers appropriately relative to sea level.

Filed: 1958-06-17
Abstract: 850,557. Respiratory appliances. ROBERTSHAW-FULTON CONTROLS CO. June 17, 1958 [June 17, 1957], No. 19388/58. Class 81(2) [Also in Group XXIX] A servo-actuated control valve assembly for high altitude use has means for applying fluid pressure, derived from the oxygen source, to the outer face of the control diaphragm. Oxygen is received into the body of the assembly through a union 22, Fig. 3, and duct 30, and is fed to a valve chamber 32 which is closed by a flexible member 40, Both sides of the member 40 are, however, connected through ducts 44, 46, Fig. 4, which are restricted by a metering choke 48, and consequently the valve normally remains closed. The user's mask is connected to the outlet 26 and, on inhalation, the drop in pressure is communicated through orifice 54, Fig. 3, to the diaphragm 56 and, when this is drawn downwards, it bears against a lever 62, Fig. 4, pivoted on a spring 74, and so lifts a block 64 and sealing member 66 away from the valve seat 58 so that the lower side of valve 40 is vented through duct 50. This causes the member 40 to be deflected downwards by the supply pressure and oxygen flows round the seating 38, Fig. 3 to the pipe 26. The upper face of the diaphragm 56 is adjacent to a perforated plate 95 forming the lower wall of a cup-shaped chamber, the upper rim 80 of which may be engaged by a plate 88 when the latter is lowered by a spring-loaded aneroid 97. The enclosed space 92 is supplied with oxygen received from the duct 30 through a communicating conduit 94 and, according to the position of the plate 88, this builds up a pressure which bears on the diaphragm 56 and tends to open the pilot valve to assist the flow of oxygen to the mask.

A nuclear fuel element comprises fissile material enclosed in a sheath permeable to infrared radiation. Removal of heat from the element takes place mainly by radiation and is thus less dependent on contact between the fissile material and the sheath. Tubes 2 of quartz or silicon carbide contain powdered or granular uranium or plutonium oxide or carbide and extend across the steel envelope or a reactor, being connected to the envelope 1, as shown in Fig. 2, by means of an elastic body 3 and a seal member 8. The tubes 2 may incorporate apertured steel reinforcing members and may be evacuated. As shown in Fig. 3, the fuel 11 is contained in crucibles 10 of graphite or silicon carbide, which may be spaced from the walls of the sheath 2 by alumina rings. If the fuel is in compressed and sintered form, the crucibles are not necessary. In Fig. 6 (not shown), fuel elements are supported in a cage-like structure. Alternatively, individual elements are arranged in a duct in a graphite moderator, a space for coolant flow being provided between the elements and the finned wall of the duct. Provision may also be made for controlling fission by circulating a neutron-absorbing fluid, for example a solution containing cadmium or boron, between the sheath and the fuel. For use in a fast reactor rod-shaped sheathed elements are arranged incooling ducts, the walls of which are corrugated and coated with infra-red absorbing material,for example nickel-chromium steel with an oxidised surface layer, or iron, steel, or molybdenum coated with aluminium. Specification 841,545 is referred to.

Abstract: 770,422. Mineral-mining machines. BRITISH JEFFREY-DIAMOND, Ltd., and SAVILLE, A. Y. April 15, 1955 [July 6, 1954], No. 19800/54. Class 68 (1). In a mineral-mining machine cutting head of the kind comprising upper and lower cutter jibs 1, 2 and an intermediate cutter extending between the outer end of the jibs, the intermediate cutter has a vertically extending, serrated cutter 3, 5 secured to a cylinder 8 resiliently attached by leaf springs 9 to a structure 12, such as is described in Specification 770,423, which is referred to, that can slew the jibs 1, 2 and the intermediate cutter about a vertical axis as a unit. The cylinder has an internal partition 17 on opposed sides of which are disposed plungers 15, 16 that extend outwards through the ends of the cylinder to engage blocks 36, 24, slidably mounted in apertures of complementary section extending through the jibs 1, 2. On the supply of pressurized liquid to the chamber on one side of the partition in the cylinder and exhaust of liquid from the chamber on the other side of the partition the ram subjected to the pressurized fluid moves outwards of the cylinder until the associated block engages the roof or floor whereupon the cylinder moves in the opposite direction. After a certain travel of the cylinder it contacts and actuates a spring- loaded mechanism that reverses a two-way valve 19 controlling the passage of liquid to and from the cylinder and the cylinder movement is reversed. Thus the cutter 3, 5 is reciprocated. The valve and actuating mechanism therefore are protected by vertical, mutually-inclined shields that can act as ploughing and loading structures.
