Patent GB-714274-A (GB)
Title: Apparatus for drying strips or other substances or articles by dielectric heating
IPC: H05B6/78
Filed: 1951-11-30
Abstract: 714,274. Dielectric heating. CUNNING- HAM, J. B., and WILBURN, F. Nov. 30, 1951 [Dec. 2, 1950], No. 28192/51. Addition to 700,467. Class 39 (3) Dielectric heating apparatus as claimed in claim 1 of the parent Specification comprises a circuit resonator with two capacitance walls 33 connected by at least one self - inductance wall 35, at least one of the capacitance walls having an aperture to permit the material to be heated to move into the electric field between the capacitance walls, the aperture having a position orientation or pattern capable of concentrating the field in the material. In Fig. 1 strips of wood 37 glued together at their edges are passed through rectangular apertures 36, an apertured drum-shaped resonator 30 directly energized by means including a valve 32 mounted on the resonator, which may be a cylindrical casing in which either the flat end walls or diametrically opposite parts of the cylindrical wall form the capacitance walls, the remaining interconnecting walls serving as inductance. The depth of penetration of heating of strip material may be decreased by increasing the depth of the aperture, by decreasing the thickness of the aperture wall 33 or the spacing of the walls 33. Thus a photographic film strip comprising a thin emulsion layer on a cellulose acetate sheet may be dried with a depth of heat penetration equal only to the thickness of the emulsion. The depth of penetration may be increased by making the aperture small or by lining the aperture with bands 41 of metal to form lateral extensions of the capacitance walls. The inner glue layer of a veneer board 43 may thus be heated. The orientation of the electric field may be altered from a longitudinal to a lateral orientation across the material by fitting adjustable or detachable capacitance plates 60 to the aperture as shown in Fig. 8. These plates are closer together than are the walls 33 of the resonator and are perpendicular or inclined to the walls. The plates may have ribs, bosses or other protuberances on the opposed faces to concentrate the field. Thus the plates 60 may have ribs in the direction of travel of the board 37, thereby intensifying the field in the glue lines of the board, which comprises strips glued at their edges. The resonator may be of doughnut form with central apertures, and where one wall only is apertured, it may act as inlet and outlet for a conveyer belt. Fishing rods may comprise six longitudinal strips of wood of triangular cross-section glued together and heated as in Fig. 15 by metal ends 72 of ceramic pressure members 70, the metal shoes 72 are pressed on to the rod by leaf springs 73 on an annular metal support 75 with a flange 76 attached to the wall 33 of the resonator. The electric field is set up with the shoes 72 as electrodes pressing on the wood to be heated.

Title: Improvements in and relating to reclaimed silicone rubber
IPC: C08J11/14
Filed: 1952-11-12
Abstract: Silicone rubber is made by (1) mixing a reclaimed, vulcanizable, solid, elastic organopolysiloxane which has been obtained by subjecting to steam pressure a comminuted solid elastic organopolysiloxane in a wholly or partially cured state, with an uncured organopolysiloxane convertible by heat to the solid, elastic, cured state, and (2) moulding the mixture under heat and pressure until an infusible and insoluble product is obtained.  The silicone rubber, constituting the material which is reclaimed, may be that made in known manner from the siloxanes described in Specifications 592,018, 594,481, [both in Group IV], and 618,453, fillers such as lithopone, ferric oxide, titania, talc, zinc oxide, silica aerogel, asbestos and glass fibres, and curing catalysts, such as benzoyl peroxide, t.-butyl perbenzoate, 2-azo-bis-isobutyronitrile and boron hydrides.  In the reclaimation, the cured rubber is disintegrated, e.g. on a heavy two-roll mill, placed in a pressure vessel, e.g. an autoclave, and subjected to steam at pressures ranging from 5 to 1000 p.s.i. Alternatively water may be added to the comminuted rubber in the pressure vessel in amount sufficient to produce adequate steam pressure.  The steamtreated rubber is then preferably dried and plasticized and may be freed from fibrous fillers if used in the initial rubber.  The reclaimed rubber may then be mixed with further curing catalyst, if it is to be used alone, or be mixed with uncured siloxane and curing catalyst and moulded under heat and pressure. Examples are given.  The use of the reclaimed rubber with the uncured siloxane is stated to improve the shrinkage and compression set of the moulded products.  Reference has been directed by the Comptroller to Specification 716,024.

Title: Improvements relating to the manufacture of silicon semi-conductor devices
IPC: H01L21/24
Filed: 1957-09-11
Abstract: 894,786. Soldering. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd., and GLASS, W. B. Sept. 10, 1958 [Sept. 11, 1957], No. 28614/57. Class 83 (4). [Also in Group XXXVI] In making a silicon semi-conductor device, firstly, a quantity of nickel is introduced into a solder and secondly, the solder is applied to a silicon element, the solder acquiring during the first step sufficient nickel to destroy, at least partially, any oxide film present on the element to enable wetting of the element. A nickel-iron disc, whose coefficient of thermal expansion is close to that of silicon, is covered with a low-melting point soft metal, e.g. tin or tin-lead alloy and is heated in hydrogen to not more than 700 C. to partially alloy the soft metal with the nickel and iron. The cooled disc has a solder coating containing up to 1% nickel. Alternatively, 1% nickel may be dissolved in tin or tin-lead alloy to form a solder and this solder and a disc of metal other than a nickel alloy are heated as before. The silicon body is contacted with the solder on the disc and heated in hydrogen to 750‹ C. to bond the body and disc now forming a contact. The nickel iron disc may be removed during cooling or by reheating and replaced by a disc of other metal or a metal lead or electrode may be attached to the wetted area. An impurity, with or without a carrier, may be applied to the wetted area to form a rectifier with a PN junction. Transistors with PNP or NPN junctions may be similarly made. Silicon bodies provided with PN junctions by diffusion may be wetted by the method described, the silicon surface being cleaned by etching before wetting. A solder of high.melting point, e.g. lead, may be superimposed on the wetted surface to bond a metal contact thereto.

Title: Improvements in and relating to carburettors
IPC: F02M9/02
Filed: 1952-11-14
Abstract: 734,529. Carburetters. WIEGEL, P. H. Nov. 14, 1952 [Nov. 15, 1951]. No. 28837/52. Class 7(3). In a carburetter for a motor cycle or for the auxiliary engine of a bicycle, the jet is located in a recess in the induction pipe and the manually operable control slide is formed with a bore one end of which is in alignment with the jet the arrangement being such that when the control slide is moved past its normally closed position it will enter the recess so as to prevent the flow of fuel directly into the induction pipe and to constrain it to flow into the bore in the slide means being provided when the slide is in this position to permit a restricted flow of air through the bore or across the end thereof remote from the jet to produce a rich fuel air mixture for starting the engine. In Fig. 1 in the closed position of the throttle valve 2 mixture for cold starting is obtained by means of passages 8, 9, 10 in the valve which co-operate with the fuel jet 6. Fig 2 shows a modification in which the throttle valve is provided with a bore 12 and is bevelled at its upper part 17. The passage provided by the bevelled part is slightly narrower at the outer side. The upper part of the slide may be recessed. Fig. 3 shows how an existing carburetter can be converted by providing a vertical bore and an oblique saw cut. In a modification of Fig. 3 the upper part of the throttle valve instead of being bevelled is cut away on its opposite sides adjacent the air inlet and mixture outlet. In another modification a horizontal bore with an orifice therein is provided in the upper part of the throttle valve. The orifice can be changed to make the carburetter suitable for different engines. The throttle control lever co-operates with a second lever. Thus in one position ofthe second lever the throttle valve can move past its normally closed position into a position for cold starting but during normal running the second lever is shifted into a position in which the throttle valve cannot be moved into a position in which too rich a mixture is supplied.

Title: Improvements in or relating to joints and couplings or jointmaking packings for pipes, rods, stuffing-boxes and the like
IPC: F16L19/10
Filed: 1931-10-16
Abstract: 391,140. Metallic packings for stuffing- boxes. LAMONT, B. N. R., 23, St. Philips Road, Surbiton, Surrey. Oct. 16, 1931, No. 28840. [Classes 122 (iii) and 122 (v).] In securing a pipe P to a socket member 2, the end of the pipe abuts against a flange 4 on a sleeve member S formed on its outer surface with circumferential grooves 3 and the sleeve is compressed axially by a nut 1 to distort it and form on its inner surface ridges 5 opposite the grooves 3. If the bore of the socket member 2 is conical, one face of the flange 3 is coned to fit it. The ridges produce minute air chambers 6. Where two plain pipe ends are to be connected, each end is provided with a flanged sleeve S and in either case each contacting surface of a sleeve may be roughened by concentric grooves to ensure a fluidtight joint when the sleeves are compressed. The flange on the nut which engages the sleeve may be conical on its inner face to press down the end of the sleeve on to the pipe or an interposed coned slip ring may be used for the same purpose. The pressing is facilitated by providing the sleeve with a thin outer edge either by increasing the internal or decreasing the external diameter of the sleeve or by forming it as described in Specification 340,074, [Group XXVIII]. When the pipe and socket member are of the same internal diameter, the flange is made of the same diameter, but when the pipe is of smaller diameter, either the flange 4 is omitted and the pipe extends into the socket or else the sleeve is of stepped formation to engage inside the socket and the pipe, a leather washer being interposed between the shoulder on the sleeve and the end of the socket member. In another form the sleeve comprises upstanding flanges 18, Fig. 10, between which are wide grooves 17 or several smaller grooves. The sleeve may comprise a flat metal strip bent into a ring with its ends abutting along an oblique line or otherwise. To adapt the coupling to make a stuffing box joint, the sleeve is formed with circumferential grooves on both its inner and outer surfaces, the grooves being in staggered relationship. Specification 378,898, [Group XXVIII], also is referred to.
