Title: Improvements in or relating to levelling valve mechanisms
Inventor: TREVASKIS HENRY WILLIAM
IPC: B60G17/052
Filed: 1959-02-07
Abstract: 935,901. Maintaining vehicle height constant. DUNLOP RUBBER CO. Ltd. Jan. 21, 1960 [Feb. 7, 1959], No. 4360/59. Class 108(2) A valve mechanism for maintaining the height of a vehicle constant comprises a casing 10, a port 17 communicating with one or more fluid springs, a port 15 connected to a source of fluid pressure, an exhaust port 16, an inlet valve 37 to connect the ports 15, 17, an exhaust valve 44 to connect the ports 16, 17, a pair of pressureresponsive devices, such as bellows 21, 22, each associated with one of the valves, and means 30 controlled by a member 35 responding to changes in vehicle height for adjusting the pressure on one or other of the bellows and thereby causing actuation of the corresponding valve. When vehicle height decreases the members 35 is rotated anti-clockwise by a lever and spring connection with the unsprung part of the vehicle to cause a resilient pad 31 to close a port 26 between the bellows 21 and the interior of the casing 10 which is at atmospheric pressure. Contraction of the bellows 21 now occurs by virtue of a connection through ducts 27 and a port 14 with a source of sub-atmospheric pressure so that the valve 37 is actuated by an arm 24 and a lever 43 to admit fluid to the spring until the body is restored to its original height. The valve 37 consists of two parts separated by a spring 39 and provided with rubber closure pads 40. The lever 43 lifts the right hand part from its seat by displacement of a tappet 41 to produce a pressure difference across the left hand part which is thus also lifted to open the part 15 leading to the supply of fluid under pressure. The exhaust valve 37 consists of a part 38A similar to one of the parts of the inlet valve and has a tappet 41A for direct engagement by an arm 25 on the bellows 22 when the vehicle height is increased.

Title: Improvements relating to Motion Pictures.
Inventor: FLOWER SAMUEL ALBERT
IPC: G03C11/02
Filed: 1918-03-12
Abstract: 123,842. Flower, S. A. March 12, 1918. Kinematograph apparatus.-In kinematograph films, the pictures are illustrated by the application thereto of words or numerals, so disposed that they appear to issue from the speaker's mouth, the word or the separate letters of the word being successively displaced as shown in Figs. 1 and 2, separate letters only being employed in the film shown in Fig. 2. The words &c. disappear when the mouth is closed, and may be produced on the film by employing a negative bearing the word either in conjunction with, or separate from, the negative of the picture, successive displacement of the word negative being necessary between each printing. Alternatively, a negative film bearing the words &c. of the same length as the picture negative may be employed. In a second modification, the words may be printed on the negative or film, or the sensitive surface may be removed. An apparatus for printing the words is shown in Figs. 4 and 5, the film passing over a toothed roller d from the shaft of which a type roller e is driven by gearing f, g. Displacement of the type roller e is effected by a half-nut i engaging screw-threads on the roller shaft e<1>. During printing, the nut is lifted out of engagement by a cam n driven by gearing k, m from the roller d, the cam serving to rock a lever q connected by a link p to the half-nut. Where the sensitive surface is to be removed, the type roller is dispensed with and graduations are formed on the shaft e<1>. Instead of printing the words on the picture film, two projecting apparatus may be employed to produce the one picture.

Title: Improvements in the manufacture from viscose of fibres resembling wool
IPC: D01D10/04
Filed: 1935-02-12
Abstract: <PICT:0451860/IV/1> Continuous filaments of cellulose xanthate are collected from a large number of spinning nozzles to form a bundle which is cut into staple fibres, and the cut fibres are opened up by a strong current of liquid which converts the cellulose xanthate into cellulose, and then forwarded in a continuous process to subsequent treatment baths.  The bundle of fibres may also be subjected to the loosening action of the flowing, washing and after-treatment liquids. For the initial precipitation of cellulose xanthate threads soluble in water or alkali, solutions of ammonium sulphate, organic acids, or dilute mineral acids may be used.  Dilute mineral acid such as sulphuric acid may be used for converting the cellulose xanthate threads into cellulose threads.  The conversion bath may contain sodium sulphate or an oxidizing agent such as hypochlorous acid, hydrogen peroxide, or a substance obtained by causing a hypochlorite to react with p-toluene sulphonamide.  The artificial fibres obtained are strongly and permanently crimped and may be used as a substitute for wool.  As shown, cellulose xanthate threads, obtained by extruding viscose into a solution of ammonium sulphate containing a little sodium sulphate, are passed as a thick bundle a to a cutting device c.  The cut fibres fall into trough d and are carried down tower e provided with baffles f by a stream of conversion liquid such as dilute sulphuric acid and sodium sulphate.  The fibres are received on a conveyer sieve g and transported to a further trough d and tower e where they are treated with further conversion liquid or with washing liquid. The fibres are then passed to and through similar apparatus where they are treated with washing and other liquids, and they are then passed through a drying device i.  Rollers h are provided for squeezing liquid from the fibres.  The liquids after use are collected, adjusted to the original concentrations, and returned to the towers by means of pumps m.  The fibres are loosened during passage through the towers.  If desired, the towers may be omitted and the various liquids may be vigorously sprinkled on the fibres on the conveyer sieves.  This sprinkling may be supplemental to the treatment in the towers.

Abstract: 1,139,732. F!ame desurfacing. UNION CARBIDE CORP. 2 Feb., 1966 [3 Feb., 1965], No. 4523/66. Heading B3V. The surfaces of a metal workpiece W are flame desurfaced simultaneously by separate desurfacing units 22, 24, 27, 32 movable towards and from the surfaces and which can be locked in an adjusted position. The desurfacing apparatus is generally of the automatically adjustable kind described in Specification 1,008,333 wherein the top and left side units 22, 24 are mounted on a horizontal slide 30 movable by a pneumatic cylinder 36 and carried by an upper float member 14 running on guide rollers (16), Fig. 2 (not shown), and actuated by pneumatic cylinders 18; the side unit 24 is also slidable vertically relatively to horizontal slide 30. Bottom and right side desurfacing units 27, 32 are similarly mounted on a horizontal slide 34 movable by a pneumatic cylinder 40 and carried by a lower float member 15 actuated by pneumatic cylinders 19; side unit 32 is also vertically movable independently. When the bottom unit 28 is moved upwardly by cylinders 19, the left side unit 24 is also moved upwardly through cylinder unit 50, 51, rack and pinion 53, 54, telescopio shaft 55 and rack and pinion 57, 56; this also produces a corresponding closing-off of gas ports in manifold 43 moving over fixed piston 41. Similarly downward movement of upper unit 22 produces a downward movement of right side unit 32 with closing-off of the corresponding gas ports. The loading on the rack and pinion gearing is relieved by air cylinders 95, 97. Horizontal adjustment of the upper unit 22 produces a closing-off of the gas ports in lower unit 27 by means of cylinder unit 80, 81, rod 82, chain 84, telescopic shaft 86, chain 88 and pistons 46 in selector valve assembly 28. Similarly horizontal adjustments of lower unit 27 produces a corresponding closing-off of the gas ports in the upper unit selector valve 23. In operation the units are moved inwardly into contact with the workpiece surfaces and are then locked by pneumatic brake units 120, 130, Fig. 6 (not shown) acting on piston rods 37, 39 of the cylinders 36, 40. A limited retracting movement of the units through adjustable distance (D), Fig. 6 (not shown), is then effected, the workpiece is returned to its starting position, the pre-heating gas and scarfing oxygen supplies are turned on automatically by a timer, the units are then moved inwardly through the distance D and desurfacing commences. This may be effected either by movement of the workpiece or of the desurfacing apparatus. Means (110), (112), Fig. 2 (not shown), are provided to ensure alignment of the top and bottom units. The top and right desurfacing units 22, 32 may alternatively be mounted on the upper float member 14 and vice versa.
