Abstract: 1455701 Laminates IMPERIAL CHEMICAL INDUSTRIES Ltd 3 April 1974 [19 April 1973] 18958/73 Heading B5N [Also in Division C3P and C3R] A method of making a laminated article comprises applying to the surfaces of the materials which are to be bonded together a plastisol composition of polyvinyl chloride containing an isocyanurate polymer which has been added to the plastisol as a solution in a solvent which is an effective plasticiser for polyvinyl chloride (see Division C3), followed by placing the plastisol-coated surfaces in contact and applying pressure at a temperature sufficient to cause the polyvinyl chloride to become plasticised. Prior to contacting the surfaces the plastisol may be semi-gelled by heating to 95-115‹ C. before raising the temperature to the level at which the polyvinyl chloride becomes plasticized. In the example a square woven twistless nylon fabric is coated with plastisol, semi-gelled at 110‹ C. and two layers thereof press laminated at 175‹ C. with their coated surfaces in contact.

Title: Improvements in and relating to electric arc welding
IPC: E01B11/50
Filed: 1920-07-07
Abstract: 158,215. Rail Welding & Bonding Co., (Assignees of Lincoln, J. C.). Jan. 26, 1920, [Convention date]. Uniting by fusion.-Electric arc welding of rails, ships' plates, members of bridges, buildings, &c. is effected by a carbon electrode of relatively small diameter mounted in a holder so that only a small section thereof protrudes, which is highly heated and maintained at burning temperature. The arc is maintained as short as may be drawn with a well defined crater, and the diameter of the electrode is small so that a long tapering point is produced so as to facilitate control of the arc and so as to ensure a deep penetration of the metal. In welding fish plates to rails, a carbon electrode g of 5/16 in. diameter is adjustably mounted in a massive copper holder h held by a pivoted handle h<1>, the electrode projecting 1 to 2 in. from the end of the holder. The electrode is supported by an insulated roller f, and a copper bar e is placed against the lower edge of the seam to chill the molten metal produced in welding. A current of great density, such as 400 amperes and low voltage is supplied by the generator i, so that the end of the electrode is burned to a tapering point so as to produce a short conical arc which is about 3/16 in. in diameter at its apex and 7/16 in. at its base. Additional metal supplied in the form of a flat wire k may be fused into the joint and a flux, preferably of sodium carbonate, is used, preferably enclosed in a metal tube j, which is melted under the arc. The electrode is traversed along the joint, the molten metal being impelled from left to right of the crater as the electrode is traversed from right to left.

A sound-insulating tile is formed from a dried, water-laid fibre-board made of vegetable fibres, mineral wool, or glass wool, by pressing blunt-nosed projections into the front surface to displace material and leave irregularly-shaped elongated openings 1 lined with loosely-felted fibres. The blunt projections may be on the surfaces of a succession of cylinders or on a platen of a punch-press which may be so arranged that the openings 1 are not at right angles to the surface of the fibre-board. Smaller, regularly-shaped openings may be pressed in, between the elongated openings 1, e.g. using blunt pins. A dark dye may be applied before forming the openings I, and thereafter the surface may be coated with a lighter colour. The back of the tile may be embossed to have small, regular, elongated depressions at right-angles to the general direction of the openings 1. Adjacent tiles 7, 8 may be arranged with the openings 1 at right-angles.

Title: Fluid-tight couplings for rotary cylinders and the like
IPC: F16L39/04
Filed: 1931-07-06
Abstract: 376,493. Swivelling pipe joints. DEHN, F. B., 103, Kingsway, London.- (Beloit Iron Works ; 2nd Street, Beloit, Wisconsin, U.S.A.) July 6,1931, No. 19447. [Class 99 (i).] A pressure fluid fitting for a rotary and non-rotary aligned conduit where a bearing ring is interposed between the hollow rotary journal and the stationary fitting portion so as to allow motion at right-angles to the axis of the journal, includes an expansible compartment in communication with the main fitting portion and having a transverse wall responsive to fluid pressure. The main fitting portion is tied to the rotary conduit by devices which are also connected with the fluid pressure responsive wall of the expansible compartment. The construction is particularly applicable for the steam joints of drying 'cylinders used in paper-making. As shown in the drawings, the end trunnion 9 of a drying cylinder is supplied with steam through a pipe 15 and condensate is removed through a pipe 16. Owing to expansion of the cylinder, the steam fitting moves lengthwise with the journal, and the pipes 15, 16 are therefore connected to the supply and discharge mains by universal joints or flexible connections. Pipes 15, 16 are fixed to a main fitting 18 having an interior compartment 19 communicating with the steam pipe, and another compartment 21 communicating with the discharge pipe. The fitting 18 bears against the spherical face of a ring 24 preferably of hard carbon impregnated with graphite. The opposite face of the ring bears against an annular flange 26 fixed to the journal. A second bearing ring 32 is seated on the collar 27 and bears on the surface 34 of the flange 26. A yoke structure connects this bearing ring with the main fitting and ties the assembly together. The expansible compartment 36 is formed by a tubular flexible metal siphon 37 attached to the main fitting and to an endplate 39. Tie rods 42, 43 connect the plate 39 to the ring member 35 and are located in annular and elongated holes 44, 46 which allow for slight displacement due to expansion of the pipes 15, 16. To obtain a balance of the steam pressure the effective area of the expansible member 36 is made equal to or slightly greater than the effective area of the compartment 19. The pressure on the plate 39 is resisted through the yoke structure and taken by the thrust on the flange 26. This is balanced by steam pressure in an annular shaped chamber 54 in the face of the bearing ring 32. The small pressure required for keeping the fitting steamtight may be supplied by springs 48, this pressure being independent of fluctuations in the steam pressure.

Filed: 1960-06-02
Abstract: 909,601. Testing adhesives. AVIATION, MINISTER OF. May 18, 1961 [June 2, 1960; Jan. 9, 1961], Nos. 19523/60 and 835/61. Class 106 (2). A joint made by a non-metallic adherent is tested by applying temperature changes to the joint and noting the corresponding expansion or contraction in a direction parallel to the bond, on the basis that the change of dimension will be greater for an ineffective joint than for an effective joint. In the case of a cold setting adherent a temperature gradient is set up between the two metal bodies by applying platens, gases or liquids at different temperatures and the corresponding changes in dimension are compared with those which would be experienced if the adhesive were absent. The stress, at ambient temperatures in a joint made with a hot-setting adherent may be such that no change of dimension is produced by change of temperature until a certain temperature range is reached. In this case the joint is heated and its dimension change compared with that of a standard joint. The dimension change may be measured by an extensometer comprising two vertical arms, one fixed and one pivoted on a horizontal bar. The arms have knife edges which rest on the joint and deflection of the pivoted arm due to change in dimension of the joint is measured by electronic or optical means.

Title: Improved manufacture of hydrofluoric acid from natural fluorides
IPC: C01B7/19
Filed: 1920-07-08
Abstract: Hydrofluoric acid is prepared from sulphuric acid, preferably in the form of monohydrate, and a natural fluoride such as fluorspar by thoroughly mixing equivalent quantities of the two compounds with an inert solid substance such as finely-ground anhydrous calcium sulphate, and heating to 200-300 DEG  C.  By feeding the material into a muffle furnace of the Mannheim sulphate type which is provided with mechanical stirring and discharging devices, the process becomes continuous and the handling of the resulting calcium sulphate charged with hydrofluoric acid is avoided.  The hydrofluoric acid is absorbed by means of alkalis, thereby yielding alkali fluorides.  The residual calcium sulphate is used in the preparation of fresh charging-material.
