Title: Improvements in or relating to horizontally pivoted sluice gates
IPC: E02B7/44
Filed: 1924-05-26
Abstract: 216,874. Ransomes & Rapier, Ltd., (Assignees of Sommer, 0.). May 28, 1923, [Convention date]. Sluice gates. - In a horizontallyhinged sluice gate of the type which is raised and lowered by means of ballast chambers within the gate, dash-pots are provided which check the movement of the gate and thus enable it to be maintained in any desired position. The gate comprises a float mounted on hollow horizontal pivots a<2>, Fig. 1, and having a series of ballast chamlers a. Water from upstream flows into a chamber c, Fig. 3, whence it is led by a pipe c' to a cock b bv means of which the chamber c can be put into communication either with the compartments a through the hollow pivot a<2>, or with the downstream side of the gate by means of the pipe b<2>. Formed in the gate is a series of dash-pot chambers d in which are located pistons d<1>, Fig. 1, secured to the floor of the channel. The water in the chambers d escapes through leak holes e<1>, e<2> as the gate falls. To facilitate the raising of the gate the chambers d can be connected to the upstream chamber c by valve controlled ducts k, k<1>. The dash-pot chambers d can be rapidly emptied by placing them in communication through conduits h<1> with a dis. charge passage h controlled bv a valve. The valves may be controlled either by hand or automatically by mechanism connected to the gate. The plungers of the dash-pots may be carried by the gate and the cylinders formed in the floor of the channel.

The reaction time may be between 1 sec. and 4 mins.  The carbonaceous material may be in the form of charcoal, coke, coal, graphite, coal tar pitch, wood, paper, lithium carbide or naphthalene.  The alloy may comprise 2-10% or more of each metal.  01-10 parts, preferably 0.5-2 parts, of alloy per part of carbonaceous material may be employed.  The product may be treated with fuming nitric acid.  As shown, a central cylindrical alloy slug 34 and two outer cylindrical graphite slugs 35 are compressed according to Specification 830,210 within a hollow pyrophyllite cylinder 31 and end platinum discs 32, heat being supplied by passage of an electric current through the slug assembly.  In an alternative, cylinder 31 may contain an alloy wire and a surrounding hollow cylinder of carbonaceous material.  In a further alternative, cylinder 31 may contain a hollow alloy cylinder packed with carbonaceous material.  Examples are given. Specification 871,645 also is referred to.

Filed: 1952-05-22
Abstract: 723,744. Compound transparent sheets. KASEMANN, E. May 22, 1952 [May 28, 1951], No. 12973/52. Class 140. In a method of cementing hygroscopic polarizing foils made of synthetic plastics, preferably with molecular orientation such as polarizing filters, between protecting plates made of glass or other transparent non-hygroscopic material, a homogeneous optically isotropic mixture of natural resins, e.g. Canada balsam, colophony copal resins arid turpentine and liquid cementing agents, e.g. of the class of the tertiary ethylene imines which are hardenable by polymerization is used as a binding agent, polymerization and hardening of the cementing agents taking place in the cold state or when slightly heated after the assembling of the foil and the plates. In an example for cementing between glass plates a polarizing foil made on the basis of a coloured molecularly orientated polyvinyl alcohol there is applied to the cleaned surface of one of the two covering glasses an amount of liquid cement produced by mixing 100 gms. of liquid cement obtainable under the Registered Trade Mark " Hostacoll C " with 20 gms. of Canada balsam previously dried to a hardness approximately that of glass, until completely dissolved when 4 gms. of a strong alkylating medium, e.g. dimethyl sulphate, are added and distributed uniformly, the polarizing foil is then placed upon it and the same quantity of cement is applied to the free surface of the foil and the second covering glass then put on, slight digital pressure being applied to distribute the liquid uniformly over the whole surface, the excess being pressed out and removed, the cemented filters are then kept either at room temperature or as required at higher temperature for about half-hour to an hour until the hardening has proceeded so that the covering glasses cannot be shifted.

Title: Improvements in and relating to compositions suitable for use in electric capacitors
IPC: H01B3/24
Filed: 1943-08-12
Abstract: Deterioration due to corrosion of electric condensers employing a chlorinated aromatic compound as dielectric is inhibited by the addition to the dielectric of a chlorinated quinone in an amount not exceeding that capable of being entirely dissolved in the dielectric, in general less than 10 per cent.  The chlorinated aromatic compound used as dielectric is chlorinated diphenyl, chlorinated diphenyl oxide, chlorinated diphenyl methane, chlorinated nitrodiphenyl, chlorinated naphthalene, chlorinated nitronaphthalene, or a mixture of chlorinated diphenyl or chlorinated diphenyl oxide with trichlorbenzene.  The chlorinated quinone may be chlorinated benzoquinone, naphthoquinone, anthraquinone, phenanthraquinone, toluquinone, or xyloquinone. Tetrachlorbenzoquinone, mono-, di-, or trichloranthraquinone, and trichlorphenanthraquinone may be used. Anthraquinone is chlorinated while dissolved in 95 per cent sulphuric acid, preferably in the presence of a catalyst such as ferric chloride.  The reaction is carried out at 100-150 DEG  C., the reaction mixture poured into water, filtered, and the solid product washed with dilute alkali solution, and if desired purified by distillation under reduced pressure.  Specifications 394,828 (as open to inspection under Sect. 91), [Group XXXV], and 534,216, [Group XXXVI], are referred to.

Abstract: 1459764 Valves NORBRO PNEUMATICS Ltd 7 Feb 1974 [20 March 1973 17 Oct 1973] 13262/73 Heading F2V A valve comprises a landed spool 15 slidable axially in a cylindrical body 1 containing annular elastomeric lip seals 8, 9 &c. spaced axially by apertured rings 7 having annular extensions 60. In the case of the five port valve shown, spool 15 comprises three main lands 16, 17, 18 separated by intermediate lands 19, 20. The latter define annular grooves 21 to 24 communicating with radial passages 40 opening into opposed axially extending bores 30, 31 separated by a dividing wall formed by land 17 or a plug. Bores 30, 31 respectively contain plugs 34, 35 and possibly centralizing springs. Thus, when spool 15 is displaced from its neutral position shown the flow from inlet port 3 to one or other of the working ports 5, 6 passes through passages 40 in the spool, rather than over the spool, thus reducing erosion of lip seals 8, 9, &c. The drain fluid similarly flows through the spool to ports 2 or 4. During the displaced condition of spool 15 intermediate lands 19, 20 provide support for the adjacent lip seals. The latter may be impregnated with a solid lubricant such as molybdenum disulphide. The spool may be actuated by pilot air supplied to chambers or pistons at the ends of the spool, mechanically or by solenoids. In a modification (Fig. 2, not shown) the valve has only three ports.

A machine which forms a pair of intermeshed helical coils from synthetic resin filamentary material such as nylon, the coils being particularly intended for use in a sliding clasp fastener, comprises a pair of heads 6, Fig. 3, which each rotate relative to an axial mandrel 8 whereby filaments F are wound into coils about the mandrels, and means to effect intermeshing of the coils adjacent the free ends of the mandrels. In operation, the filaments F are nipped between elements 7 at the extremities of the heads 6 to produce deformations H, Fig. 6 (not shown), which provide interlocking means for the coils, the coils then progressing along the mandrels 8 as the heads 6 rotate to be entrained by position-adjustable toothed-wheels 42 which accurately space the convolutions of the coils relative to one another and cause intermeshing thereof. From wheels 42 the intermeshed coils pass to a wheel 51, Fig. 2 (not shown), and are forced into a peripheral groove thereof by a pressure roller 76. The coils are maintained within the wheel 51 by a metal band 75 which passes over rollers 74 and moves with the wheel, and are heated by heaters 54 to relieve tension in the filaments. Finally the coils are delivered to a cooled guide 90 after being stripped from the wheel 51 by a flexible band 55. Modifications include lengthened and angled mandrels 8, Fig. 7 (not shown), and means for facilitating the moving of the coils from the free ends of the mandrels 8 to the wheel 51, Figs. 8-10 (not shown).
