Title: Laminating process
IPC: B32B17/10
Filed: 1972-11-09
Abstract: 1461255 Laminates IMPERIAL CHEMICAL INDUSTRIES Ltd 5 Feb 1974 [9 Nov 1972] 51682/72 Headings B5N and B5A A laminate comprising at least one rigid alumina bonded to at least one glass lamina which forms a surface of the laminate, is produced by a process in which bonding is brought about by photopolymerization of an ethylenically unsaturated material comprising at least one ethylenically unsaturated monomer in the presence of a photoinitiator system capable of initiating polymerization of the monomer when exposed to radiation of suitable wavelength, the photoinitiator system comprising a photosensitizer and a reducing agent capable of reducing the photosensitizer when the latter is in an excited state. The glass lamina may be bonded to the rigid lamina which may be of wood, metal, glass, concrete or solid or foamed polymer material, e.g. polyurethanes, amino resins, polyesters, polycarbonates or polyacrylates, optionally containing fibrous reinforcement, e.g. polyethylene terephthalate, nylon, glass or carbon fibre, pigments and other fillers, by photopolymerization of an adhesive comprising the ethylenically unsaturated material. Alternatively the rigid lamina itself may be a polymer formed by photopolymerization of the ethylenically unsaturated material in contact with the glass lamina, e.g. in a mould. The ethylenically unsaturated monomer may be styrene, vinyl toluene, divinyl benzene, methyl methacrylate, methacrylic acid, ethyl acrylate, vinyl acetate, acrylonitrile or N-vinyl pyrrolidone or a mixture thereof, which may be used in admixture with isocyanates, polyols, unsaturated polyesters, polyethers, polystyrene and polymethyl methacrylate. The -photosensitizer may be a compound of the formula in which X is >C=O, >CR 1 R 2  or >CR 3 OR 4 , in which R 1  to R 4  are hydrogen or hydrocarbyl groups, n is 0 or 1 and the groups A are hydrocarbyl or substituted hydrocarbyl groups, the groups A being aromatic or substituted aromatic when n is 1 and X is >CR 1 R 2  and when n is 0, e.g. benzil, and the reducing agent may be a primary, secondary or tertiary amine, e.g. dimethylaminoethyl methacrylate or dimethylaminoethanol. Visible or ultraviolet light may be used for the polymerization reaction. The adhesive may contain a particulate or fibrous reinforcement material, e.g. a printed lightweight or open-mesh fabric. Glass/interlayer adhesion may be improved using newly formed glass, a glass lamina chemically treated with trimethoxy vinyl silane, an adhesive containing polar hydrophilic groups, e.g. a vinyl urethane resin, or adhesive having a low shrinkage during curing. Laminates comprising a thin layer of low melting glass bonded by a photopolymerizable adhesive layer to a thermoplastic lamina or partially cured reinforced thermosetting material layer or a thin layer of low melting glass bonded to a glass fibre reinforced uncured photopolymerizable unsaturated polyester resin, may be softened by heating and shaped, e.b. by winding on to a cylindrical mandrel to form a pipe, prior to photopolymerization and curing.

Abstract: 1468461 Data compression INTERNATIONAL BUSINESS MACHINES CORP 29 Nov 1974 [26 Dec 1973] 51734/74 Heading H4P A system of data compression for computer, facsimile, or video information providing reduced transmission time or storage comprises generating sets of signals in accordance with the length of the runs of said data signals, each of the sets of signals including an event designation signal and asignal representing the event designation number, a first predetermined length of the runs of said data signals being represented by a special event designation signal and a second predetermined length of the runs of said data signals being represented by a regular event designation signal, an encoder table for supplying a plurality of prior established signals, and a second encoder responsive to each set of signals for selecting from the encoder table established signals corresponding to each set of signals, the second encoder combining the signal representing the event designation number of each of the sets of signals with its corresponding selected established signal to provide sets of encoded compressed data signals. The second encoder may comprise a subtractor of known complement adding and sum inversion form and the events are designated, purely arbitrarily, as (i) regular, e.g. a set of 7 run lengths codes and (j) special, e.g. end of line or page. Data events are recognized at 10, when enabled at 37, which defines on line 12 regular or special status and an event number is placed on cable 11. Encoder 14 selects the appropriate word and then combines it with event designation number to provide a compressed signal which is supplied parallely to 17 for conversion to serial form. The decoder operates in approximately reverse manner except that tables are subdivided into parts as there is no prior indication as to whether they are regular or special. The arrangement is stated to be particularly suited to employment of standard semi-conductor modular elements. Table selection circuitry may be used in preference to random access. Encoder and decoder tables include a plug board arrangement (e.g. 150-3, Fig. 4, not shown) so that code words may be changed, examples of (i), (j) codes being given in the Specification. Details of logical arrangements are described to perform the various functions involved. A slightly simplified arrangement is described in connection with Fig. 19 (not shown).

Filed: 1964-12-21
Abstract: An explosive composition comprises nitroglycerine, glycol dinitrate or isopropyl nitrate, adsorbed on finely divided carbonaceous fuel, an oxidizing salt, and water.  The composition is flowable, but sufficiently viscous to prevent segregation of the ingredients. Suitable carbonaceous fuels are woodmeal, ryeflour, wheatflour, paper pulp, foamed rubber, polystyrene or polyurethane, charcoal, coke, or carbon black.  The preferred oxidizing salt is ammonium nitrate; others referred to are sodium, potassium and calcium nitrates, chlorates, and perchlorates. Urea, ethylene glycol and glycerine may be added to reduce viscosity and guar gum, with or without zinc chromate, to increase viscosity.  The addition of dinitrotoluene lowers sensitivity. Paraffin oil or wax may also be present and diammonium phosphate, chalk and urea act as antacids.  A small amount of nitrocellulose may be added to increase the viscosity of the nitroglycerine. Aluminium, magnesium and ferrosilicon may be present as additional fuels.

Title: Improved fluid discharge mechanism for directing fluid from a movable nozzle
IPC: F28G15/04
Filed: 1966-12-06
Abstract: 1,133,949. Soot blowers. DIAMOND POWER SPECIALTY CORP. 6 Dec., 1966 [24 Jan., 1966], No. 54621/66. Heading F2N. [Also in Division B2] A soot blower 10 is provided with a fluid discharge mechanism comprising a tubular nozzle body 45 secured to the end of a rotatable and extendible lance tube 15, a nozzle ball jet 50 universally rockable in the nozzle body to different angular positions relative to the axis of rotation of the lance tube and nozzle body, and means for thus rocking the ball jet during the rotation of the lance tube so that a liquid, e.g. water, jet is discharged at varying angles to said axis of rotation. Rocking of the ball jet is achieved by disc 68 which is rotatably mounted in the nozzle body and which is connected by a pin 55 having one end threadly secured in the ball jet and the other end journalled in an eccentric hole 66 formed in the disc. The lance tube is projected, rotated and retracted to and from its operative position within a boiler by an air motor 28 through reduction gear 30, shaft 32 and gearing 34, a control unit 36 regulating the number of blower operations and terminating said operations when desired operating cycle has been completed. Rotation of the disc 68 at a different relative rotational speed to that of the lance tube and nozzle body to effect rocking of the ball jet is also achieved by said motor through chain drives 77, 80, tubular shaft 74, and a square shaft 72 secured to the disc at one end and telescopically received in the tubular shaft at the other. However, rocking of the ball jet would also be achieved by maintaining the disc stationary. The fluid flow through the ball jet is variably throttled by an element 90 fixed in the nozzle body which progressively obturates the inlet of the flow passage through the ball jet as the inclination of ball jet outlet passage relative to the nozzle body axis decreases. In a modification, Fig. 6 (not shown), the obturating element is formed by a pin (90B) extending axially from square shaft (72b).
