[Class 36] [Also in Group XL (a)] In electrostatic precipitation apparatus the deposit on the insulators of solid or liquid particles is avoided by the formation of an ionized electric field, in which the particles are charged and subsequently precipitated towards the wall of the apparatus, the ionised electric field being obtained by means of a disc placed between the insulator and the gaseous atmosphere, the disc co-operating with a cylindrical member within which it is situated. The insulators are arranged at the downstream side of the apparatus. Thus, an insulator 4 through which passes the rod 5 carrying the cross-rod 6 from which the high potential precipitating wires 3 depend into the air current tubes 2 is provided with a disc 7, whereby an ionized field is formed between the disc 7 and the wall 8 of the apparatus, the wall 8 being earthed. Any remaining particles travelling towards the insulator 4 must first go through the ionized field 9, where they are charged and thus driven by the electric field towards the wall 8.

Filed: 1959-09-14
Abstract: 883,241. Cooling nuclear reactors. ESSO RESEARCH & ENGINEERING CO. Sept. 14, 1959 [Nov. 12, 1958], No. 31221/59. Drawings to Specification. Class 39(4) Heat is removed from the core of a nuclear reactor by circulation of a cooling fluid comprising a material which undergoes an endothermic reaction in the presence of a catalyst in the vicinity of the fuel elements. The preferred cooling fluid is a cyclohexane-benzenehydrogen mixture; the cyclohexane is dehydrogenated to benzene in the presence of a platinum, palladium, nickel, or platinumalumina catalyst coating on the fuel elements. The coolant leaving the reactor is regenerated in a tube steam boiler where the benzene is hydrogenated back to cyclohexane by means of a nickel, platinum, or palladium catalyst on the tube surfaces ; this is an exothermic reaction which provides heat for the production of steam in the boiler. Part of the coolant from the boiler may be recirculated back through the boiler in order to reduce the temperature to that at which hydrogenation takes place. The nuclear fuel elements may comprise stainless steel conduits with plates of uranium 235 encased in stainless steel; platinum catalyst is applied to the stainless steel cladding by means of an electric arc sputtering device or by electroplating.

Abstract: 954,352. Steering motor vehicles. HYDROSTEER Ltd. June 29, 1960 [Sept. 14, 1959], No. 31303/59. Heading B7H. In a motor vehicle power assisted steering mechanism having a follow-up action, there is provided a power control valve having resilient means biasing it to its neutral position, the biasing force increasing with the displacement of the valve, means being provided to reduce the biasing force as the valve reaches its limiting displacement. A manual steering control comprises a steering shaft 6, a worm 19 and nut 20 provided with circulating balls 21, the nut being carried by a rocker arm 22 on a rocker shaft 23 coupled to the steering transmission. The nut is connected by a rod 26 to a double acting piston 24 and a limited amount of axial play is provided in the steering shaft to operate a valve 1 controlling the supply of pressure fluid to the piston. Liquid is supplied to the valve through connection 3 and returned to the reservoir through connection 4, there being means to convey liquid to each side of the piston. The valve comprises a housing 2, a spool 1 provided with a ball 5 engaging a groove in the steering shaft 6, and an insert 16<SP>1</SP>. The spool has control faces 9, 10, 13, 14 which may co-operate with closing rings 11 and 12 and faces 15 and 16 on the insert 16<SP>1</SP> respectively. Spring rings 17 and 18 bias the spool to the neutral position, Fig. 1, in which liquid can flow past the faces 13 and 14 and past the rings 11 and 12 to the return connection 4. When a steering movement is commenced, the valve spool is moved by the reaction against the pressure of spring 17, Fig. 2 (or 18 if in the opposite direction). The face 9 co-operates with the ring 11 to direct the fluid to the appropriate side of the piston and the faces 14 and 16 come together to seal that side of the piston from exhaust. At the limiting position, when faces 14 and 16 are in contact, the fluid pressures acting on the spool 1 are unbalanced (owing to the change in areas contacted by the fluid) to provide a bias opposing that of the spring.

Abstract: 832,729. Letting-off warps in looms. NEW YORK WIRE CLOTH CO. Oct. 11, 1957, No. 31808/57. Class 142(2) [Also in Group XXXIV] A constant warp tension is maintained, in spite of the variation in the length of the warp path when the shed is open, by a resilient flexible member 38 secured to the shaft of the warp beam at one end and to the loom frame at the other end. When the shed opens, the member 38 is flexed and when the shed closes the member returns to its initial state. The invention is described in connection with the weaving of wire threads. The beam shaft carries a brake housing 48 and the hub 50 of the brake has a portion 40 to which the member 38 is secured by a pin 42. Just before the healds reach their position of maximum displacement the brake yields to allow the warp beam 20 to turn more when delivering warps than when turning back to maintain the tension constant. This arrangement compensates for the amount of cloth wound on the cloth roll.  To allow for the decreasing weight of the warp beam the spring pressure on the brake plates can be adjusted by a nut 68. A device 24 over which the warp passes indicates the warp tension and visible or audible means indicates when the nut 68 should be turned.
