Title: Apparatus for manufacturing glass ribbon
IPC: C03B18/06
Filed: 1968-07-03
Abstract: 1,219,809. Flat glass manufacture. NIPPON SHEET GLASS CO. Ltd. 3 July, 1968 [7 July, 1967], No. 31837/68. Heading C1M. In float glass apparatus the float tank contains a pair of dams 10, 10<SP>1</SP> disposed in spaced relationship to define a path for the glass ribbon to be formed, the dams being spaced from and extending parallel to the side-walls over at least part of the length of the tank and extending above the bath level, and means to control the flow of molten metal between each dam and the adjacent side-wall. In the preferred embodiment the dams 10, 10<SP>1</SP> extend upwardly from the tank bottom. They are made of a gas permeable material 13, preferably graphite, and have on the inside of such material a longitudinal cavity 14 into which a non-oxidizing gas is fed. Gas permeating the material 13 prevents contact between the dam 10, 10<SP>1</SP> and the glass ribbon. The dam is also water cooled. The flow of molten metal 31, 31<SP>1</SP> between the dams and the sidewalls 22, 22<SP>1</SP> is controlled by water-cooled graphite dampers 21, 21<SP>1</SP> which can be located in the molten metal bath to desired depths. The combination of dampers and dams reduces the flow of molten metal beneath and parallel to the moving ribbon and reduces contamination of the undersurface of the ribbon. In an alternative embodiment a rotatable water cooled graphite roller is located in the channel defined between the dam 10 or 10<SP>1</SP> and side-wall 22, 22<SP>1</SP>. Other alternatives mentioned are pairs of adjustable dampers wholly immersed in the molten metal 31, 31<SP>1</SP> or the use of induction motors to set up a forced flow of molten metal. If there is no contact with the glass ribbon spheroidal graphite cast iron may be used in place of graphite. Reference has been directed by the Comptroller to Specification 1,103,276.

Abstract: 465,953. Jacking vehicles. STEVENSON JACKING SYSTEM, Ltd., and STEVENSON, J. F. Nov. 18, 1935, No. 31857. [Class 79 (iii)] A jacking lever 1 is pivoted to the lower end of a bar or bracket 2 which, at its upper end, is non-turnably and detachably carried by a sprung part of a vehicle. The bar may be of channel formation with a lateral projection 2<a> of square cross-section adapted to engage a transverse socket member 3 attached to the chassis side member 4 below the running-board 5 or a longitudinally disposed socket member at the end of the chassis frame. A plurality of holes 2b may be provided in the bar 2 and/or the lever 1 for adjustment of the fulcrum pin 1<a>. The lever, which may terminate in a ground engaging shoe 6 or roller 7, may be of right angle form as shown in Fig. 4 in which case it is pulled down to raise the vehicle or of the form shown in Fig. 1, in which it is raised and retained in the vertical position indicated by a stop and hook or by a pin inserted through registering holes in the lever and bar. Instead of a single lever 1, the parts thereof on opposite sides of the fulcrum 1<a> may be connected by reduction or ratchet gearing. To enable jacking to be effected in stages, the bar or support 2 may carry a telescopic extension 8, Fig. 5, moved downwards by a spring 9 or by gravity as the lever is raised, being sustained by a catch 10 whilst the fulcrum pin is transferred to a lower hole 2b. A similar effect may be obtained by means of a block pivoted to the lower end of the bar 2 and which falls into position to form a support as the bar 2 is raised. The lever 1 may be successively pivoted to the bar and the block or it may be initially secured to the block as a ground engaging element. The block may be a loose member inserted under the bar 2 manually. The operation of the lever 1 may be facilitated by running the wheel or wheels of the vehicle on to a suitable elevating block or support. When employing a ground engaging shoe 6, the lever 1 operates in the longitudinal direction of the vehicle, but when provided with a roller 7 it may be mounted transversely.

IPC: D06M13/432
Filed: 1936-11-23
Abstract: Hydrophobic properties are imparted to fibrous materials comprising nitrogenous substances of high molecular weight and of colloidal character by incorporating with the fibres a urea derivative or an aliphatic monocarboxylic acid amide free from hydroxyl groups containing an alkyl group having at least 11 carbon atoms and then causing the compound on or in the fibres to react with an aliphatic aldehyde.  Preformed condensation products may be used and acid substances may also be present in the treating baths.  Suitable fibres include wool, natural silk, casein or gelatine artificial silks, animal hair, felts, bodies made from horn, tanned or untanned hides, and acetate artificial silk containing a basic nitrogenous polyvinyl resin.  Suitable ureas or amides include lauric acid amide, stearoylmethylamide, stearoylbutylamide, stearoyloctadecylamide, or the corresponding methylol compounds.  The process may be applied after a pre-treatment such as the treatment of wool with chlorine or hydrogen peroxide.  In examples: (1) wool piece goods are treated in a bath containing lactic acid then in a carbon tetrachloride bath containing montanic acid methylolamide and then heated, (2) wool piece goods are impregnated in an ethyl alcohol-carbon tetrachloride bath containing stearic acid methylolamide and lactic acid and then heated, (3) wool piece goods are impregnated in a hot solution of montanic acid methylolamide in tetrachlorethane, (4) artificial fibres from rennet-casein are impregnated with a solution of N-heptadecyl-N1-methylolurea and lactic acid in alcohol and carbon tetrachloride and heated, (5) wool gabardine is impregnated with a solution of stearic acid amide in carbontetrachloride, dried, and impregnated with aqueous formaldehyde containing lactic acid and finally heated.  The Specification as open to inspection under Sect. 91 refers also to pre-treatment of the fibre with ethylene oxide, propylene oxide, epichlorhydrin or similar compounds and contains examples of pretreating wool piece goods with ethylene oxide followed by treatment as in example (2) of the Specification as accepted and of pretreated dyed natural silk piece goods with butadiene dioxide followed by impregnation in a bath containing methylolcarbamic acid octadecyl ester in tetrachlorethane followed by drying.  The Specification also refers to the use as urea derivative of mono-iso-butylurea.  This subject-matter does not appear in the Specification as accepted.

Abstract: 754,635. X-ray apparatus. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. Nov. 8, 1954 [Nov. 12, 1953], No. 32240/54. Classes 97 (1) and 98 (1). An optical system for viewing the image formed on the screen 8 of an image intensifier tube (Fig. 2) comprises a support structure, an objective lens 14, mirrors 15, 16 supported at an angle of other than 90 degrees to the optical axis of the lens and positioned to form a light path including the optical axis, a third mirror 17 positioned to receive light projected from the mirror 16, and at least one field lens pivotally mounted on the structure for movement into and out of operative position in the light path. Two field lenses 18, 19 may be pivoted to the structure to be movable alternatively into operative position in the light path. As shown in Fig. 4, a mounting ring 6 which supports the image intensifier is carried by a member also carrying the X-ray tube and adjustably mounted on a tiltable patient table. Ring 6 supports a bearing plate 21 and a toothed ring 24 shaped above it. Rings 25, 26 grip the edge of plate 21 by plastic lined surfaces so that a housing 12 for the optical system, supported on ring 25, rotates freely on plate 21. A spring-biased plunger 27 engages toothed wheel 21, but may be disengaged by a bar 28 on the front of the housing and linked to the plunger for turning the housing within limits set by stops. The objective lens 14 is mounted in a cylindrical holder 33 slidably axially on shafts 35 by a fork 38 pivoted about a shaft 36 journalled in the housing and fast with a rod 37. The lenses 18, 19 are respectively mounted in holders fast with shafts 45, 42 and sprockets 46, 44. A chain 47, tensioned by an idler sprocket 48, passes over sprockets 46, 44 so that when one of the lenses is swung from operative to inoperative position, the other swings from inoperative position. At the same time, rod 37 is rocked by a spring connection 52 to chain 47, so that lens 14 is moved axially to its other position wherein it is held by spring action against stops, thus changing the magnification of the system. Counterweights 52A, 52B balance the lenses 19 and 14. The holders of lenses 18, 19 are held in operative position by magnets 54, 53. The light emerges through a glass window 55 in the housing wall to an adjustable mirror 56 so that the image can be viewed from any convenient position. The lenses, window 55, and the mirrors have coated surfaces. Specification 652,451 is referred to.

Title: Improvements in or relating to electrodes or rods for welding
IPC: B23K35/40
Filed: 1929-10-25
Abstract: 337,589. Aitchison, J. H., Bull, H., and Johnson, L. Oct. 25, 1929. Uniting by fusion.-An are-electrode or welding rod for welding alloys comprises a billet &c. composed of one or more metals of the alloy to be welded and provided with one or more longitudinal cores or coverings of the other metal or metals of the alloy, the composite billet being worked into a composite electrode by rolling, forging or drawing. One hole of the billet may contain two or more of the other metals of the alloy disposed concentrically therein and the hole or the exterior of the billet or the core may be coated with one or more of the metals by electrodeposition. The core may be composite when the alloy contains a great number of metals, e.g. a sleeve or liner containing elements such as tungsten, manganese, vanadium, silicon &c. may be interposed between a nickel core and a chromium steel billet, or the additional metals may be in the form of powder. One or more of the alloying metals may be inserted in a hole in the billet by casting or a central core may be secured in place by casting one or more metals in the annular space between the core and billet. In a modification the composite billet is formed from a central core by adding the other materials to its exterior by electrodeposition. spraying, wrapping or casting. In an example, an electrode for welding stainless steel containing 15 per cent chromium and 11 per cent nickel is made from a billet of chromium steel containing 20 per cent chromium and 0.1 per cent carbon, a hole in the billet being filed by a nickel core secured by welding or riveting. The diameters of the hole and rod are so chosen that the nickel represents approximately 10 per cent of the weight of the composite billet which is then heated and rolled to form a rod. The rod is next annealed if necessary and then cold drawn to the required size of the electrode which, in use, melts to form a welding joint containing 0.09 per cent carbon, 18 per cent chromium and 8 per cent nickel.

Abstract: 768,041. Electromagnetic couplings; automatic tension control systems. T.M.M. (RESEARCH), Ltd. Dec. 30, 1955 [Nov. 10, 1954], No. 32542/54. Classes 35 and 38 (4). Winding tension is kept constant by means of a coupling comprising a D.C. excited driven field member, and an A.C. generating driving member, the A.C. output being rectified and used to excite the field member. As shown, the winding drum 10 is driven by a coupling 12 whose outer field member is driven by a chain 24. Polyphase current is drawn from the inner armature at slip-rings 122, rectified at 13 and fed back through a rheostat 14 to the field member at slip-rings 124. The transmitted torque may be additionally controlled with respect to the winding diameter by means of a rider on the spool controlling the rheostat through a cam. To economize power, the rectifier output may be fed into a series motor in the transmission to the spool 10. An arrangement is described for driving the coupling from an auxiliary machine to build up its field current while winding tension is developed. Fig. 9 shows how a carbon-pile resistor 142 in the coupling field circuit may be controlled by the tension of the wound material 20, so as to regulate this tension.

Title: Process and apparatus for firing porcelain or ceramic material in electrically or indirectly heated tunnel furnaces
IPC: F27B9/04
Filed: 1935-11-26
Abstract: 460,386. Tunnel furnaces. KERAMISCHE INDUSTRIE-BEDARES-AKT.-GES. Nov. 26, 1935, Nos. 32740 and 32741. Convention dates, Dec. 22, 1934 and Oct. 4, 1935. [Class 51 (ii)] In an electrically or muffle-heated tunnel furnace for firing porcelain or like ware requiring a reducing atmosphere at a certain stage in the heating operation, the ware-carrying trucks are fitted with containers for reducing gas or for solid or liquid material adapted to produce such gas by evaporation or gasefication. In the form shown, a container f for liquid fuel is arranged on the truck b below the platform c, the latter being formed with a slot e or a row of nozzles for the passage into the furnace tunnel a of the gas generated by the gradually increasing temperature to which the truck is subjected during its forward travel. If desired, the container f may be fitted with a heating coil g to which current from a conductor rail i is supplied by a collector brush h. The production of the reducing atmosphere may be regulated in various zones of the furnace by subdividing the container or providing a number of containers so as to permit the use of different fuels which evaporate at different temperatures. Instead of liquid fuel, the container may be filled with compressed gas, the escape of which through the slot e is automatically controlled by valves actuated by the movement of the truck. Additional feed devices k are arranged to supply liquid fuel through channels m which open into the furnace slightly above the truck platform c. A modification is described in which the substance producing the reducing gas is contained in dishes arranged on the platform c or in recesses formed therein. In a further construction, the platform c is formed of porous fire-clay which is saturated with the atmosphere-producing substance before the truck enters the furnace.
