Title: Method of sealing a stopping and withdrawing head in a continuous casting mould
IPC: B22D11/08
Filed: 1972-02-25
Abstract: 1386633 Continuous casting CONCAST AG 25 Feb 1972 [25 Feb 1971] 8907/72 Heading B3F A mould having at least two adjoining walls movable out of the casting position is closed ready for casting by inserting a starting head and a seal, after withdrawing the movable walls away from the casting axis, and then returning them to the casting position so that the gap between the head and walls is closed by the seal. The seal may be placed on the head before the latter is moved into the mould and may be protected against guiding elements by a removable sheet metal hood while the head is being inserted. A slab mould may have one fixed wall and three walls movable by hydraulic cylinders for adjustment to different slab sections. The head may be prepared with a seal while a preceding cast is in progress. The walls deform the seal so that an effect equivalent to ramming of the seal is produced. A sealing card may be covered with a heat-protection layer of chill scrap, or an asbestos cord containing soft steel wires, as described in Specification 1,368,653 may be used.

Title: Process of polymerisation
Inventor: ROEBUCK DAVID SAMUEL PETRIE
IPC: C08F291/00
Filed: 1957-03-19
Abstract: Graft polymers are prepared by treating with a polymerization catalyst anaqueous dispersion of a polymer or copolymer obtained by the emulsion polymerization of a vinyl compound such that active centres are induced in the trunk of the polymer, and then introducing an additionpolymerisable monomer which graft polymerizes directly on to the active centres to form branches. Polymers specified are those of ethylene, propylene, styrene, butadiene, isoprene, vinyl and vinylidene chlorides, vinyl acetate, acrylonitrile and methyl methacrylate and copolymers thereof, e.g. styrene-butadiene and styrene-butadiene-divinyl benzene copolymers.  Monomers specified are styrene, butadiene, acrylonitrile, methyl methacrylate, vinyl chloride and vinyl acetate.  Polymerization catalysts specified are potassium persulphate, tert. butyl peracetate and tert. butyl hydroperoxide. The aqueous polymerization medium may contain a dispersing agent. In an Example (6) a graft polymer obtained by polymerizing a mixture of styrene and butadiene on to a styrene-butadiene copolymer is mixed with natural rubber, aluminium silicate and conventional vulcanizing recipe ingredients and then vulcanized. Specification 847,603 is referred to.

Title: Frame support for panels
IPC: E04B2/96

Abstract: 832,132. Glazing, walls. PITTSBURGH PLATE GLASS CO. March 20, 1958 [March 29, 1957; Dec. 5, 1957], No. 8936/58. Classes 20(3) and 20(4) A glazing bar 60 used for the securing of glass panels 20 or spandrels 21 to the framework of a curtain wall is of the section shown in Fig. 12. The glass or spandrel is secured on the inturned flanges 76 by a clamping member 90 screwed into the flange 74 upstanding from the web 70. A cover 100 is snapped over the clamping member 90. In horizontal glazing bars only there is a longitudinal flange 82 extending from the web 70 and a drip flange 80 with a convex under surface depending from the flange 74. Drainage and ventilation holes 83, 84, 98, 106 and 107 are provided in the assembly and the surface of flange 74 may be slotted as at 81. Several modifications in the form of a flange 74 are described. The panel edge is covered with tape. Curtain walling is constructed on a frame work of vertical and horizontal box-section members 26, 50. The horizontal members 50 fit over and are secured to channel members 29 attached to members 26. Where it is required that the walling form a quadrilateral the end of a side wall of a member 50 is slotted so that the member may be slid into position over the channel member 29. Wood setting blocks 115 spaced horizontally on member 50 are covered with metal flashing 116 bent to form rear and side flanges 118, 122 and a front flange 117 overlapping the flange 82 of the glazing bar 60. Between the flanges rests a pad of heat insulating material 124 such as glass fibres bonded to masonry 30. The back of the pad is provided with a vapour barrier coating. The members 50 may be hidden by sheeting 131, 134 secured to ceiling and floor respectively. To permit expansion of the framework the vertical members 26 may be replaced (Fig. 6) by opposed channel members 27 bolted to angle brackets 31 secured to the masonry 30. The glazing bars are also modified as shown. To prevent ingress of water the gaps between the channel members are covered at one end by a strip 168 and at the other by a glazing compound 171.

Patent GB-1103653-A (GB)
Title: Method and apparatus for sputtering
IPC: C23C14/28
Filed: 1965-03-02
Abstract: In a sputtering process of depositing a material on a substrate a radio frequency electric field is established between a pair of sputtering electrodes in a low-pressure atmosphere, the field being such as to form a plasma between the electrodes. The material is sputtered from both electrodes which may be of the same or different material and the coating layer may be formed of a single material, layers of different material, a composite consisting of a mixture of the different material from both electrodes or as a graded layer varying in composition from the material of the first to the material of the second electrode. The sputtered materials may be Cu, glass, quartz, porcelain, BeO, permalloy; the substrates specified are conductors, insulators and semi-conductors such as Si and glass.  The sputtering is carried out at 10-6 to 10-3 Torr and the sputtering atmospher may be inert e.g. argon, or reactive e.g. oxygen or nitrogen which would result in the formation of metal oxides or nitrides.  The frequency of the applied RF field is 1-100 megacycles/sec. A baffle or shield may be located in the sputtering chamber and may be moved so as to obstruct the sputtering from one of the electrodes. Alternatively the shield may be located within the Langmuir sheath zone of an electrode (within 1/2" of electrode surface) and is then itself sputtered to form part of the coating. The specific examples relate to coating a Si wafer with glass; a Si wafer with a layer of glass, a layer of Cu and a further layer of glass; by using a permalloy shield a Si wafer is coated with glass/copper/permalloy/glass.

Title: An improved apparatus for diminishing the recoil of guns by utilising the reaction of the gases of the exploded charge
IPC: F41A21/36
Filed: 1920-03-30
Abstract: 146,929. Schneider et Cie. June 27, 1919, [Convention date]. Ordnance design. - Relates to muzzle attachments for reducing recoil, of the kind comprising a tube laterally perforated by a series of rings of orifices, and having check plates attached for deflecting the escaping gas. The invention consists in (1) providing the tube with a number of continuous longitudinal portions on its interior surface whereby the projectile is guided while passing through the attachment, and (2) providing means whereby the projectile is not disturbed by gas eddies. In the construction shown in Fig. 1, the longitudinal strips A<1> separating the rows of gas orifices are either grooved, so that the grooving of the attachment, and the rifling of the bore are continuous, or the attachment is bored out so that its internal diameter is the same as the diameter of the bottom of the rifling grooves. When the projectile has uncovered the ring of orifices a<2>, a portion of the gas passes up channels e in the outer check plate E, and is first deflected outwardly and then inwardly and to the rear, as shown by the arrows. The projectile having uncovered the orifices a<3>, this gas impinges on the gas following up the projectile, and retards the flow.
