Title: Improvements in or relating to valve arrangements for the control of liquid flow to a positive-displacement hydraulic starter motor
Inventor: TURNER HORACE GEORGE
IPC: F16K1/42
Filed: 1960-10-21
Abstract: 995,371. Valves. PLESSEY CO. Ltd. Sept. 29, 1961 [Oct. 21, 1960], No. 36121/60. Heading F2V. Fluid flow from an inlet 2 to an outlet 3 connected to an engine starter 20 is controlled by a main closure member 5 embodying a collar 6 with ports 7 and a piston flange with a restricted passage 10 therethrough; a filter 11 is associated with the latter. When the pressures on both sides of the piston flange are equal the member 5 is spring closed. Upon operating a solenoid, as shown, or an hydraulically-actuated half-ball pilot-valve 13 to relieve the pressure behind the piston flange, the member 5 opens. Downstream of the member 5 is a trip valve 15 comprised of an adjustable spring-loaded piston 16 with an aperture 17, the valve 15 cutting-off the supply of fluid to the outlet 3 when the flow rate is high enough to create a given pressure-drop across the aperture 17. This valve ensures that the supply to the starter ceases when the latter reaches de-coupling speed. The valve 15 incorporates a small through-bore 19 to permit passage of some fluid when the valve is closed. The pilot valve solenoid may be de-energized by a time switch or a manual switch.

Divided out of 423,025. [Classes 110 (i) and 122 (iii)] Comprises a method of storage and utilization of energy by utilizing external energy to drive through an electrical machine MG, acting as a motor, a compressor C which draws in steam by evaporation of water supplied to a constant pressure or displacement accumulator VS and compresses and delivers it to an upper water-andsteam drop accumulator OS from which steam is drawn off to drive a turbine which drives the machine MG, acting as a generator, the exhaust steam of the turbine being utilized to heat the accumulator VS. Two devices V<1>, V<2> arranged in series act as evaporators for the compressors C, or as condensers for the turbine T. The compressor has multiple inlets V<3>, V<4> and multiple outlets F<1>, F<2>, F<3> and the contents are cooled by a series of sprays controlled by a cock C<2>. The steam from the compressor is passed through a heat-exchange apparatus U<1> through which liquid with a higher boiling point than water is circulated from a superheat accumulator U<1>S. In a modification, the heat-exchange may take place in the accumulator U<1>S. The stored heat superheats the steam on its way to the turbine. The lostenergy heat due to friction, &c., is eliminated by an auxiliary turbine a. Part of the condenser circulating-water passes through a cooling-tower KT. The part a may be cut out of action by shutting off the cooling water to the condenser. In a construction with separate evaporators and condensers associated with the compressor and turbine respectively, the lostenergy heat is removed by a cooler placed between the bottom of the accumulator US and the evaporators or condensers. Specification 423,025 is referred to. The Specification as open to inspection under Sect. 91 describes the use of an upper accumulator working on the circulatory or displacement principle, and the use of solid bodies, such as metals or ceramic substances, for the storage of the superheat. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the production of hydrogen peroxide
IPC: C01B15/026
Filed: 1954-12-21
Abstract: Hydrogen peroxide is produced by interacting a liquid secondary alcohol containing 3-12 carbon atoms in the molecule and oxygen at a temperature of about 70-160 DEG C. in a plurality of reaction zones, e.g. 2-5, through which the alcohol is successively passed.  A substantially constant concentration of hydrogen peroxide is preferably maintained in each zone.  The temperature is preferably decreased progressively from zone to zone in the direction of liquid flow.  In a three zone process the temperatures in the respective zones may be 140-160 DEG C., 130-140 DEG C. and 120-130 DEG C.  The same amount of hydrogen peroxide is preferably produced in each stage.  The secondary alcohol is preferably an aliphatic alcohol containing 3-8 carbon atoms, e.g. isopropyl alcohol.  The alcohol may be employed as an azeotropic mixture with water.  The oxygen may be in the form of air, oxygen-enriched air, substantially pure oxygen, or mixtures of oxygen and helium, carbon monoxide or methane.  The reaction may be carried out under pressure, e.g. 35 atmos.  The reactors may be constructed of, or lined with, glass, porcelain, aluminium, tin, stainless steel or a resin.  A hydrogen peroxide stabilizer, e.g. potassium pyrophosphate may be employed.  The reaction may be initiated by the addition of an organic or inorganic peroxide including hydrogen peroxide itself.  The hydrogen peroxide may be recovered from the crude product by distillation or by precipitation as calcium peroxide followed by treatment with acid.

Abstract: 960,854. Welding by pressure; brazing. ROLLS-ROYCE Ltd. Oct. 5, 1962 [Oct. 13, 1961; Jan. 19, 1962], Nos. 36899/61 and 2132/62. Heading B3R. [Also in Division G6] A method of making a nuclear fuel element comprises coating the interior of a stainless steel sheath with nickel or a nickel-phosphorus alloy and the exterior of a fissile mass with nickel, and forming a diffusion bond or a brazed joint therebetween at 800-1050‹ C. The fissile material may be uranium, a uranium alloy, or a uranium compound, the fissile material being dispersed in a non-fissile material, such as a ceramic. Examples of uranium compound given are uranium monocarbide, uranium nitride, and uranium dioxide. After the nickel has been deposited on the surfaces of the fuel components to be assembled within a single can by vapour deposition, and on the can (e.g. by electrolytic, vapour, or chemical deposition), an axially bored end plug is placed in the can after insertion of the fuel components. The assembly is placed in an oven under external pneumatic pressure (300-500 lb./sq. inch), and the assembly interior connected to a vacuum source, through the plug bore. The external pressure collapses the can into intimate contact with the fuel. The oven temperature is raised to between 800‹ and 1050‹ C., at which temperature metallic diffusion of the nickel takes place without it actually melting. The can may be formed by welding or brazing together a plurality of parts, and the excess metal resulting from collapsing the can may be absorbed in part forming axially extending integral projections of the can to act as spacers when assembled. Fuel element assembly.-Fuel elements 14 with end plugs 20 therein are assembled about a cone 12 by welding them to plates 27 which are held in slots 26 on the cone 12 by a swaged ring 28. The lower ends of the fuel elements are restrained by a ring 30. Each fuel element has two integral projections 22, 23 (Fig. 4) which locate it with respect to the annular space 13 and adjacent fuel elements. Holes 25 in these projections allow coolant pressure to be equalized between adjacent flow paths. In a modification (Fig. 7, not shown), the projections from a wedgeshaped cross-section fuel element extend outwardly from the element along the longitudinal axis of the section.
