Title: Improvements in fluid control valves
IPC: G05D7/06
Filed: 1953-08-07
Abstract: 790,993. Valves. BROADBENT, S. Nov. 8, 1954 [Aug. 7, 1953], No. 21909/53. Class 135. A fluid control valve comprises a body with a bore formed by the assembly in axial alignment of two or more rigid components positively spaced apart to provide at least one narrow, annular port gap at which the fluid flow is controlled by a sealing element of an axially displaceable valve member movable across the port gap. According to Fig. 1 the valve body consists of an intermediate part 8 and end members 9, borings 10 in each part being in axial alignment to receive a closure member 11 which has resilient sealing rings 22 mounted in grooves. A reduced part 20 of the closure member connects an inlet 15 with either of a pair of outlets 13, 14 depending upon the position of the closure member. The outlets 13, 14 communicate with annular grooves 16 which open to the bore 10 through narrow annular gaps g formed between annular parts 17 of the intermediate member and the end members 9. In a modification the valve body is formed of three elements clamped between end members 9, Fig. 2, by a bolt 29 upon which the valve member is slidable. The upper member 9 has a connection 33 whereby fluid pressure may be admitted to the upper end of the valve member to depress it against a loading spring 32. Each of the intermediate members has a fluid connection 12, 13, 14 opening into an annular channel 16 which communicates with an annular gap g. A modified form of valve body consists of a number of outer rings having the fluid connections and clamping between them inner rings which provide the annular gaps g. Fig. 4 illustrates another form of the invention in which inlet pressure from a connection 12 passes through a port 61 in the valve member to a chamber 47 where it acts continuously in an upward direction on the valve member. The inlet pressure also passes through bores 50, 39 in a member 44 which holds the body parts together to a push-button pilot valve 53 which controls the application of pressure to the upper surface of the valve member 11, whereby the member may be depressed against the loading of the pressure in the chamber 47. In a further modification the application of pressure fluid to each end of the valve member is controlled by separately operable pilot valves. Further embodiments of the invention are described in which actuation of the valve member is by fluid pressure under the control of a pilot valve actuated by a solenoid. A push-button valve may also be provided to override the solenoid valve. In another embodiment the valve member is actuated by a foot pedal acting through rack and pinion mechanism. The parts in which the bores 10 are formed may, alternatively, be tubular elements which are separated from each other to form the annular gaps g by small integral projections.

Title: Process for the treatment of aluminiumsilicates of the kind of montmorillonite for the treatment of beer or wort
IPC: C12H1/044
Filed: 1951-09-19
Abstract: In the preparation of absorbents for the treatment of beer and wort to remove substances such as albumen, montmorillonite-type aluminium silicates are treated for the removal of arsenic with hydrochloric acid at a concentration of at least 5 per cent and preferably between 10 to 15 per cent, and then washed with a solution of a neutral salt of an alkali metal such as sodium chloride of such a concentration that swelling is inhibited.  When calcium bentonite, or other non-swellable material, is being treated, such a washing solution serves the dual purpose of removing acid and replacing calcium by alkali metal.  A small amount of alkali or ammonia may be added to the washing out liquid to aid neutralization.

Filed: 1938-07-25
Abstract: 518,715. Colour photography. KODAK, Ltd., and JELLEY, E. E. July 25, 1938, No. 22045. [Class 98 ii)] In the reversal processing of a colour photagraphic element comprising three emulsion layers inseparably coated on the same side of a single support, of which one of the outer layers is not specially colour-sensitized, while the other two layers are specially colour-sensitized to different colours, the latent, images are developed to silver, and after removal of the negative silver images a filter dyestuf which is substantially transparent .to all visible ray,s but opaque to ultra-violet, or transparent to all visible rays except, violet, is temporarily introduced, and the residual silver halide of the outer layers is made developable by exposing such layers successively to light from which the middle layer is protected by the temporary dyestuff. After removal of the said dyestuff, the middle layer is exposed and developed. In an example, the film is developed and subjected to a permanganate reversing, bath. It is then cleared with aqueous bisulphite containing Naphthol Yellow, a bath of sodium sulphate and acetic acid being used to remove the surface layer of yellow dye. The front and back layers are separately exposed to violet or ultra-violet light and colour developed, the two steps being spaced by a treatment with the Naphthol Yellow -bisulphite bath and rising. The film is then exposed to white light and. the middle layer colour developed. The metallic silver is removed from all the layers. Reference is made to the colours to which the layers may be developed. Specifications 440,032, 475,784, 475,786, 500,717, 500,793, 507,841, and 500,826, are referred to.

Abstract: 824,055. Thermionic valves. MACHLETT LABORATORIES Inc. July 12, 1957 [Aug. 13, 1956], No. 22168/57. Class 39(1). In a discharge tube in which a low amplification factor, i.e. between 3 and 10, is required, the grid has a plurality of parallel wires which are also parallel to the anode and cathode, the wires being spaced apart sufficiently widely to produce a variable mu across the cathode, and the effectively emitting portions of the cathode are restricted to the areas thereof where the mu is relatively low. In the arrangement of Fig. 2, both grid and cathode are formed of a series of separate wires, respectively 18 and 33. The spacing between the grid wires is considerably greater than the grid-cathode spacing, so that a variable mu effect between adjacent grid wires is obtained, Figs. 4 and 5 (not shown). As shown, the cathode wires 33 are located midway between the grid wires, where the mu is at a minimum, there being no emissive portion in the higher mu areas adjacent the grid wires. In the alternative arrangement of Fig. 6, the cathode 38 has emissive strips 41 lying between and parallel to the grid wires 40. The completed tube may be constructed as in Fig. 1 (not shown.)

Abstract: 732,986. Switch cases; switch contacts. ENGLISH ELECTRIC CO., Ltd. Aug. 28 1953 [Sept. 3, 1952], No. 22175/52. Class 38 (5). An isolator switch mounted in a casing 1 intended to be supported by an overhead bus-bar distribution system by bolts 3 and connected to the bus-bars through contacts 2, comprises pairs of fixed contact clips (not shown) located in insulating channels 4 having covers 5 provided with slots through which pairs of movable contact blades 17 may pass to bridge the respective fixed contact pairs. One fixed contact of each pair is connected to a contact 2 whilst the other is connected to one end of a cartridge fuse link 6, the other end of the fuse being connected to the load. Each pair of blades 17 is connected by a bar 18 and mounted on an insulating block 16 slidable on a rod 15. The rod 15 is supported by clamps 11 on a lid 7 of the casing and a spring 19 on the rod biases the blocks 16 towards the left-hand clamp 11. The arrangement is such that when the lid 7 is open the contacts 17 are slightly to the left of the position they occupy when the lid is closed to engage the contacts 17 with the respective fixed contact pairs. Thus the contacts are self-aligning. Further, the blocks 16 may be held in a displaced position on the rod 15 (shown in chain-lines in Fig. 3) so that when the lid is closed the contacts 17 do not engage the fixed contacts but enter spaces to the right of the channels 4, end to this end a latch 20 is pivoted by a screw 21 on the left-hand clamp 11. The latch 20 is spring-biased to the position shown in Figs. 1, 2, but may be set in the position shown in Figs. 3, 4 to hold the blocks 16 displaced, the latch being retained in this position by friction between itself and the adjacent block 16. The position of the blocks is indicated by an " off," " on," indicator carried by the centre block 16 and visible through a window in the lid 7 (Fig. 5, not shown). The lid 7 is operated by a handle 13 and held closed by a latch 8 projecting through a hole 10 in the lid. In another construction described with reference to drawings accompanying the Complete Specification (not shown), the movable contacts 17 are carried by a hinged flap retained closed by a ball-and-socket catch, the casing being closed by an outer hinged door.

Title: Improvements in or relating to crimped yarn
Inventor: DEELEY JOHN COLIN
IPC: D02J1/22
Filed: 1959-07-03
Abstract: In a combined process of drawing and crimping undrawn or incompletely drawn, low or zero twist yarn composed wholly or mostly of continuous filaments of a synthetic linear polymer, e.g. a polyamide, polyester, polypropylene, polyurea or polyurethane, the yarn, as it approaches a draw roll, is caused to engage frictionally a flange on the roll which thereby rapidly rotates the yarn about its axis and so imparts false-twist thereto.  The twist is set by passage of the yarn around a heated snubbing pin or over a hot plate or by hot nitrogen, steam, infra-red radiation, molten metal, or a high frequency electrical field, with which the action of a swelling agent may be combined. The draw roll, and/or the yarn in the vicinity of the surface thereof, may be cooled, as by an air jet or circulation of a fluid in the roll.  The feed roll (or the snubbing pin) may be offset in relation to the draw roll so that the yarn approaches the latter at an acute angle to the axis thereof.  The flange may be integral with or detachable from the draw roll and of material which withstands abrasion and grips the yarn, e.g. glass, ceramics, polyamide, polyurethane, alumina, carborundum, stainless steel, or elastomer such as rubber or synthetic rubber; the contour constitutes a surface of rotation generated and defined by a curved "geodesic" line connecting the points at which the yarn makes and breaks contact therewith, and may be convex, conical or concave.  The potential crimp induced by the falsetwisting and setting operations is developed, prior or subsequent to twisting the yarn and/or converting it into fabric, by relaxation, the effect of which may be assisted by (gradually applied) heat, e.g. by hot air and steam.  The relaxation may occur within controlled limits, e.g. the yarn may be overfed as it proceeds from draw roll to forwarding nip rolls via a hot zone: if the nip rolls are heated this zone is unnecessary.  Additional heat-setting, optionally with swelling agents, e.g. water or steam, may be effected after relaxing the yarn.
