Patent GB-2166785-A (GB)
Title: Blowout preventer
Inventor: JONES MARVIN RICHARD
IPC: E21B33/06
Filed: 1985-11-11
Abstract: A blowout preventer has means G to connect the bore beneath the closed rams with chambers behind them, whereby, with the rams closed, well fluid pressure acts over at least part of the area on the outer ends of the rams to provide a force which supplements hydraulic operating pressure in maintaining the ram packings in sealing engagement. Means 40,41 are provided in only one of the rams 26B for connecting the chamber behind it with the bore of the housing above the closed rams for venting well fluid in order to reduce the forces acting on the ram prior to opening movement of the rams, so as to facilitate withdrawal of the rams from a closed position. <IMAGE>

Title: Improvements relating to spas or whirlpool baths
Inventor: MURFIN JOHN
IPC: G11B33/04
Filed: 1985-08-05
Abstract: A spas or whirlpool bath has a bath tub (30) with water jets (32) mounted in the side of the bath tub. A pump (16) is arranged to draw bath water from a suction inlet and pump water out through the jets. The pump outlet is connected to a first, common, generally-horizontal conduit (54) which runs along underneath the bottom of the bath tub, and the jets are connected to the first conduit by a plurality of second conduits (52) extending vertically upwards from opposed sides of the first conduit. The inlet channel to the pump and the said first conduit are constituted by a common composite moulding. The first conduit drains through a restricted drain aperture (86). The structure is particularly easy to fit to a bath tub and yet is effective in operation. The waste outlet of the bath is closed by a stopper (146) which is mounted on a shaft (144) for operation by rotation of a cover plate (150) above the bath waste aperture (36) between 90<o>-separated open and closed positions. The coupling mechanism between the cover plate and the stopper is accommodated in the chamber (104) and works with a bayonnet type of movement defined by a pin (154) and the lower edge of a guide boss (140). The stopper is resiliently mounted on the shaft (144) so as to seat properly against the waste outlet (108) regardless of the thickness of the bath. The waste outlet closure mechanism is positive and reliable, and can be used in a shower or conventional bath.

Patent GB-2175245-A (GB)
Title: Device for producing ceramic mouldings
Inventor: BUHLER EUGEN
IPC: B22F3/02
Filed: 1986-05-01
Abstract: The device comprises an isostatic press-mould half (10) having an isostatic pressure membrane (16) and an injection head (12) having an inlet opening (12f) for introducing granulate and an extraction orifice (12 l ) for sucking the granulate in or out of the mould cavity. The injection head (12) is spring-mounted (34) on a press crosspiece (14) which supports it, so that, as the injection head moves towards the isostatic press-mould half, a sealing pressure slowly forms between the injection head and the isostatic press-mould half and as the injection head moves away from the isostatic press-mould half this sealing pressure is slowly reduced. <IMAGE>

Title: Controlling drilling tool
Inventor: NURMI VEIJO
IPC: E21B44/00
Filed: 1986-09-09
Abstract: In a method of controlling a drilling tool in rock drilling for automatic drilling of several adjacent holes, the drilling tool (2) is shifted from hole to hole along a shifting level (S) situated at a distance from the rock surface (1). In order to avoid unnecessary shifting movements of the drilling tool and to speed up the drilling, the drilling tool is shifted from one hole to another (R4, R5, R6) along shifting levels (S5, S6) defined individually for each hole. The shifting levels can be determined on the basis of a constant safety distance (C), a sensed location of the rock surface or an estimated form of the rock surface. <IMAGE>
Patent GB-2189898-A (GB)
Title: Light valve
Inventor: HUMPHREYS RICHARD GEORGE
IPC: G02F1/133
Filed: 1986-09-10
Abstract: A light valve for a thermal imager comprises a liquid-crystal cell containing a viscous liquid-crystal (18) material which is at least partly non-monomeric. The polymeric liquid-crystal material has a viscosity in excess of 5 poise, and may have a viscosity exceeding 100 poise, as compared to monomer liquid-crystal viscosities between 0.3 and 1.0 poise. The material may be a mixture of alkyl cyanobiphenyl material and a polysiloxane side-chain copolymer. This has been found to have the advantage of greatly reducing the undesirable degree of noise generated in prior-art light valves. The liquid-crystal cell includes two spaced- apart polyimide pellicles (12, 14) containing therebetween the liquid-crystal material. One pellicle (12) has a surface layer (26) which is transparent to visible light but absorbing to another wavelength interval such as infra-red. The cell may be arranged with a quarter-wave plate between a polariser and an analyser to form the light valve. The light valve may be arranged as part of a thermal imager to provide a visible-light image of a thermal scene. <IMAGE>
Patent GB-2187179-A (GB)
Title: Method of preparing perfluorosilanes from perchlorosilanes
Inventor: KITSUGI NAOMICHI
IPC: C01B33/107
Filed: 1987-02-03
Abstract: A perfluorosilane such as Si2F6 or Si3F8 is prepared by reaction between a perchlorosilane such as Si2Cl6 or Si3Cl8 and a metal fluoride such as ZnF2 or SBF3 the reaction is carried out in a nonaqueous liquid medium such as n-butyl ether. By using the liquid medium the reaction proceeds smoothly, and the desired perfluorosilane is obtained at high yield. Preferably a saturated hydrocarbon such as n-decane is added to the liquid medium to prevent the reaction system from becoming viscous as zinc chloride is formed.

Abstract: A lifting leg (10) for use in raising and lowering large loads, such as mobile offices and freight containers comprises a first leg portion (11) to be supported by the ground, a second leg portion (12) which is telescopically slidable relative to the first leg portion (11), a lift hitch (13) secured to the second leg portion (12) and projecting laterally therefrom, and a reaction hitch (14) secured to the first leg portion (11) and projecting laterally therefrom. A lever-operated ratchet device (17) controlled by a lever (18) can be operated in either direction, in order to lengthen or shorten a length of chain between its hooked ends (16) which are attached to respective ones of the hitches (13, 14). A slot (19) is formed in the wall of the outer tubular leg portion (12), and the hitch (14) provided on the inner first leg (11) extends through the slot and is movable relatively along the slot during relative movement of the leg portions (11, 12) during raising and lowering operations. A pin (20) can be used to lock the leg portions in any required position, and a shear pin (21) can be used to arrest downward movement of leg portion (12) in the event of failure of the ratchet device. <IMAGE>

Patent GB-2196301-A (GB)
Title: Glass-etching
Inventor: MARTIN JOHN VICTOR
IPC: C03C15/00
Filed: 1987-09-22
Abstract: An image is etched in glass by transfer to the glass surface of a pattern delineating the image, from a carrier of tissue paper or plastics film onto which that pattern has been copied electrophotographically using toner composed for example, by weight, of at least approximately 10 parts carbon black to 90 parts styrene butyl methacrylate, and fused to the carrier by radiant heat. For the transfer, the carrier is bonded to the glass surface with the toner-pattern down onto that surface, and the carrier when plastics film, but not tissue, is then stripped away from the toner-free areas prior to the etch by acid or sand-blast. Copying may be onto a carrier-coating of cellulose-based varnish which disperses from the toner-free areas during the fusing of the toner, and the carrier may be bonded by heat-rolling to the glass surface using an adhesive that adheres to the toner alone. <IMAGE>
