Abstract: 325,924. Murray, H. D., and Spencer, D. A. Dec. 24, 1928. Ornamenting.-A coloured or other design is produced on a compound transparency on the intermediate sheet or on the glass sheets by means of a diazo photographic process. Lightsensitive diazo compounds are used on one or more of the plates and a design produced thereon by exposure behind a design or negative. The plate is then bathed in an alkaline solution of a coupling agent and formed into a compound transparency. One plate may be printed beneath a. green colour-selection positive &c. and coupled to give a red image, a second beneath a blueviolet colour-selection positive and coupled to yellow, and the intermediate film sensitized with ferroprussiate blue printing solutions exposed beneath a red selection negative. The three images are registered to give a three-coloured picture and united to form a compound sheet. By ultimate swe11ing and shrinking of the substratum, e.g. by means of water, alcohol, &c. for gelatine coatings, a reticulated or ageing effect may be produced. Specifications 322.598 and 323,301, [both in Class 20 (iii), Doors &c.], are referred to in the Provisional Specification.

Abstract: 1362118 Hydraulic transmissions; valves SUNSTRAND CORP 24 Aug 1972 [14 Sept 1971] 39470/72 Headings F2D and F2V A hydrostatic transmission in which a variable displacement axial piston pump 14 supplies fluid to a motor 16, shown as fixed displacement but optionally variable, through flow and return conduits 18, 20, has a by-pass valve 120, which acts as a starting valve to allow by-pass to occur on an initial rise in pressure in conduit 18 or 20 to limit acceleration and then closes on further pressure increase and also acts to limit and control hydrostatic braking. The valve, shown in Fig. 2, has identical axially movable spools 133 and 135, biased apart by a spring 139. Each spool has lands 144, 145, peripheral passages 142, 146 and a central bore with which a bore 150 communicates and which has a member 153 with a central passage 154 and a radial bore 155 and through which fluid can reach the end of the spool to move it towards an abutment 129, contact between which and the spool causes passages 142 to be closed off. In operation, with conduit 18 being the flow conduit, an initial pressure rise in the conduit is slowed by fluid passing through passages 142 in each spool to pass through the valve 120. Eventually the pressure rise, transmitted through the various passages to the back of spool 133, moves the spool to close off the valve. On sudden reduction to neutral of the pump 14 and the motor 16 acting as pump the pressure in conduit 122 drops and that in 124 rises to move spool 133 back to the illustrated position to provide by-pass and reduce braking, a check valve 159 opening to hasten this. This pressure eventually moves spool 135 to the right to give a controlled braking.

[Also in Division D1] Siliceous materials are provided with adherent polymeric coatings by a process comprising polymerizing an ethylenically unsaturated material, which is normally polymerizable by a free radical mechanism, with a two-component initiator comprising (i) a complex of a transition metal and (ii) an organic compound which contains a carbon-halogen bond and a group which forms a stable chemical bond with a siliceous surface, the polymerization being effected in the presence of a surface of a siliceous material. The siliceous material may be glass, silica or a natural silicate mineral, e.g. mica and asbestos, and may be in massive form or in the form of sheets, fibres or particles. The polymerizable material may be a vinyl pyridine, acrylic or methacrylic acid or an ester, amide or nitrile thereof, an aralkene (e.g. styrene), vinyl chloride, vinylidene chloride or a vinyl ester (e.g. the acetate). In the initiator component (i) may be a carbonyl, or part carbonyl, or isocyanide of Fe, Co, Ni, Mo, Cr, W, Mn or Re; the carbonyl may be used in conjunction with, or reacted with,-a phosphine compound. Preferred as component (ii) of the initiator are compounds of the formula X 3 C-Y-SiZ 3  where X is halogen (e.g. Cl or Br), Y is a direct link or a divalent organic radical and Z is halogen or a hydrocarbyloxy group, e.g. an alkoxy group. The polymerizable and initiator components are generally applied to the siliceous material by means of organic solvents or diluents. Polymerization is generally assisted by photochemical or heat radiation, and additives such as fillers, pigments and heat or light stabilizers may be present if desired. The coated siliceous materials have good dye receptivity (see Division D1). In examples, the following are polymerized: (a) methyl methacrylate, (b) 4-vinylpyridine, (c) methacrylic acid, (d) 2-hydroxyethyl methacrylate, (e) 2 - t - butylaminoethyl methacrylate, (f) ethyl acrylate, (g) styrene, (h) acrylonitrile, and (i) vinyl acetate.

As shown, a valve 72 slidable in a valve body 46 is provided with appropriate lands and seals to enable the proportioning valve 88 to be bypassed through bores 66, 51 and 74 when loss of pressure in the front-brake system due to failure therein results in the valve being moved (by rear brake hydraulic pressure), to the right. At the same time, ball 116 is depressed by land 91 to close the circuit of a warning lamp L. If the rear brake system fails, the valve is moved to the left, whereupon land 87 serves to switch on the lamp L.

Title: Improvements in or relating to methods of forming articles of thermo-plastic material and presses for carrying out such methods
IPC: B29C43/02

Abstract: 860,558. Hydraulic presses for gramophone records &c. TELEFONAKTIEBOLAGET L. M. ERICSSON. Nov. 23, 1959 [Dec. 10, 1958; Sept. 15, 1959], No. 39667/59. Class 87(2). A thermoplastic article such as a gramophone record is moulded in a hydraulic platen press containing a mould and having valves controlling the supply of pressure fluid for operating the movable press platen, and valves determining the duration of steam and a cooling water supply to channels in the mould having inlet and outlet lines, which mould is initially heated by high pressure steam with the outlet lines open, and then by steam with said lines throttled or closed. Mould parts 7, 8 are located between a fixed upper platen 1 and lower platen 2, displaceable by a piston 3 slidable in a cylinder 4. Steam supply to the mould is adjustable by valves V9, V10, the latter having a check valve V20, pressure fluid to cylinder 4 is adjustable by valves V5, V6, and a valve V11 having a check valve V12 controls the discharge of steam or cooling water from the mould. Valve V10 may be switched to supply cooling water instead of steam to the mould, valves V6, V9, V10, V11 are operated electrically by solenoids 6, 9, 10 11, but valves V5 is operated by a link 5 associated with a protection gate 12. With the mould at a steady high temperature, Fig. 3, valves V10, V20 supplying throttled steam and valve V12 being either throttled or closed, gate 12 is lowered, valve 5 actuated so that platen 3 is raised, the mould closed, and contact 18 closed. A timing relay TR21 is thus started and after a predetermined period a second relay TR22, Fig. 2 (not shown), which causes valve V10 to be switched, so that cooling water is supplied to the mould and valve V11 to be opened so that is passes freely therethrough. Relay TR23 is actuated after TR22 and operates valve V6 so that the mould is opened, contact 18 opened, and relays TR21, TR22 released so that V10 resumes the supply of throttled steam. Thereafter V9 is actuated to supply high pressure steam and on the expiry of the delay time of relay TR25, valve V11 is switched so that the outlets from the mould are obstructed or throttled by valve V12 and the cycle may be repeated.
