Patent GB-1533469-A (GB)
Title: Liquid crystal display cells
IPC: G02F1/1337
Filed: 1976-08-20
Abstract: In a twisted nematic liquid-crystal display cell, a specific inclination of the nematic director is necessary on the inner surface at least of one of the glass plates (1, 2) forming the cell, in order to evade problems of inverse inclination. A five-degree oblique vapour deposition of SiO delivers an excessively large inclination and slows the response time of the cell. The angle of inclination is reduced by coating the five-degree oblique vapour deposition with the aid of a surface treating agent which produces a homogeneous orientation. <IMAGE>

Title: Improvements in or relating to apparatus for treating material with gases
IPC: F27D9/00
Filed: 1931-12-18
Abstract: In apparatus for treating solid material with gases comprising, as described in the parent Specification, two spaced perforated walls or grids between which passes the material to be treated by gas flowing through the grids, at least one of the grids is formed of separate rotary elements.  Fig. 1 shows a construction in which both grids are constituted by driven rollers, the front rollers 1 being of non-metallic refractory material and of uniform diameter, while those constituting the rear grid 3 are <PICT:0385109/III/1> <PICT:0385109/III/2> formed of iron and increase in diameter downwardly as shown at 4, 5.  In the modification shown in Fig. 2, the front grid is formed of cruciform rotary elements 10 and the rear grid is constituted by an endless band 11 which may be formed either of perforated plates as shown or of inclined slats connecting a pair of endless chains.  In this form, the gas outlet may be arranged between the runs of the band 11 so that the outer flight thereof is disposed in the open air.  Scrapers for cleaning the outer side of the rear grid are shown at 6, 7, Fig. 1, and at 13, Fig. 2, the removed material being returned to the column 2 through valve 8 and shoot 9.  A further construction is described in which both grids are similarly formed of hollow air-cooled rollers having radial perforations through which the cooling air escapes, these air jets serving to keep the grid openings clear.

Title: Double universal joint
IPC: F16D3/33
Filed: 1934-12-07
Abstract: 430,226. Universal joints. HARDY, SPICER, & CO., Ltd., Birch Road, Witton, Birmingham. Dec. 7, 1934, No. 35176. Convention date, May 4. [Class 80 (ii)] A double universal joint has driving and driven forks connected respectively to an intermediate yoke by coupling members and is positioned by ball-and-socket means one member of which is slidable with respect to its associated fork. The joint is of general application but is described in connection with the front wheel drive of a motor vehicle. The driving shaft 11 terminates in a fork 12 co-planar with a fork 13 on the driven shaft 14. Between the forks is a yoke 15 formed with a pair of arms 16, Fig. 4, to be connected to fork 12, and a pair 17 to be connected to fork 13. The connection is effected by coupling members 18, Fig. 2. Each of the arms 12, 13, 16, 17 has a hole in which is inserted a thimble 19, held in position by a spring ring 20, and engaging its trunnion 21 through roller bearings 22. The trunnions have an oil reservoir at 28. The space containing the rollers is enclosed by a flexible annular seal 24 with interposed cork packing 25. To take the weight of and position the joint, shafts 27, 28 are provided, the shaft 27 carrying a slidable ball 29 coacting with a socket 30 fast on the shaft 23. When the shafts are aligned, the centre of the ball is on the line 31 slightly off-set from the centre line of the yoke, but when the steerable wheel is locked fully over and the driving and driven shafts at their maximum inclination, the centre of the ball will be substantially coincident with that of the yoke. To ensure efficient lubrication, the ball-and-socket device is enclosed in a casing 34 made in parts relatively slidable and provided with annuli 35 coacting with ball portions 36 on the shafts 27, 28 a felt or other packing 37 being provided outside each annulus. One of the ball portions, e.g. that on the shaft 28 is slidable and loaded by a spring 38.

Title: Improvements in or relating to ships' davits, and luffing gear therefor
IPC: B63B23/04
Filed: 1928-11-29
Abstract: 324,172. Barclay, J. S. Nov. 29, 1928. Davits of the gravity type which have an athwart ship movement on inclined guides accompanied by a luffing movement occuring at the termination of the athwart ship movement have these movements controlled by falls which running from a winch 17, pass over a pulley 18 on the davit frame 4 and back to a pulley 20 coaxial with the roller 18 after the fall has been looped around a pulley 19 on the davit 9. The fall finally passes over fairleads 21, 22 to the boat. This arrangement constitutes a triple purchase gear for controlling the movements of the davit on the guides 4. The fall further controlling the luffing movement of the davit about the roller 11 until the base of the davit abuts on the stop 16 whereupon the fall acts as a single purchase gear during the boat-lowering operations.

Title: Improvements in or relating to valves for controlling fluid flow
IPC: F16K5/04
Filed: 1959-10-27
Abstract: 865,943. Valves. EDWARD VALVES Inc. Oct. 27, 1959 [Nov. 14, 1958], No. 36357/59. Class 135. [Also in Group XXVI] A valve, such as a cylindrical plug valve, comprises a housing 10 having inlet and outlet ports 12, 14 communicating with a chamber 16, a closure member 38 having grooves 56, 58, 60 surrounding the ports when the valve is closed and a composite sealing-ring 54 located in each of the grooves, the ring comprising a metal backup ring 62 and a resilient sealing-ring 64 bonded thereto. As shown, the lip 68 of the ring is proud of the back-up ring and the surface of the plug so that, when the latter is assembled into the housing, the lip is compressed into sealing contact therewith and thus maintains a seal at low pressures. When the valve is closed and subjected to line pressure in either direction, the controlled fluid, at the upstream side, enters a clearance-space between the groove 56, 58, 60 and the resilient sealing-ring 64, which may be of synthetic rubber, thereby forcing the lip 68 and portion 70 of the ring into firm sealing engagement with the housing and plug respectively, any extrusion of the rubber being prevented by the back-up ring; the shape of the lip 68 permits any build-up of pressure in the chamber 16 to leak away through the sealing- ring at the downstream side of the valve. In the construction of valve shown in Fig. 7, a tubular sleeve constitutes the body of the valve and is closed at its ends by plates 82, 84, thereby permitting easy access to 0-ring seals 108, 110, 116, 118. The sealing-ring arrangement may be applied to gate valves (Fig. 8, not shown) and to spherical plug valves. A drain hole 75 is provided for draining the chamber 16.
