Title: Method and apparatus for welding with gas shields having laminar flow
IPC: B23K9/173
Filed: 1951-02-19
Abstract: 684,011. Welding. FAIRWEATHER, H. G. C. (Air Reduction Co.). Feb. 19, 1951, No. 3989/51. Class 83 (iv). In a method of electric arc welding with a consumable electrode, an annular stream of gas is continuously flowed downwardly around the electrode and arc, laminar flow of the stream being maintained by confining its cross-section and co-ordinating its velocity with the cross-section so as to keep the Reynolds number below 3000 immediately upstream from the arc. Apparatus comprises a guide 20 through which an electrode 22 is fed, a housing 10 having a sleeve portion 11 with an outlet adjacent the arc end of the electrode for discharging an annular stream of gas around the region of the arc and weld, and an enlarged gas chamber 12 at the upper end of the housing having a cross-section substantially larger than the cross-section of the stream of gas supplied through said sleeve portion, said chamber connecting with the upper end of the sleeve portion. A baffle 17 deflects the incoming gas, and fins 35 in the upper portion of the sleeve restrict the gas flow to parallel columns and reduce the Reynolds number of the passages. The fins are thin and their lower ends are tapered to sharp bottom edges, so that the gas streams will merge into a continuous annular curtain. The tube 20 is of copper and conveys current to the electrode through brushes 29 formed at the lower end of the tube by slotting the tube wall and swaging inwardly to a diameter slightly less than the diameter of the electrode wire. A cooling coil 32 is wrapped around, and preferably bonded to, the bottom portion of the sleeve, whose length is of the order of not less than 20-50 times the diameter of the equivalent circular cross-section of each passage between the fins. The invention can be used with any of the gases commonly employed for shielding the arcs of non- consumable electrodes, or with mixtures of gases corresponding to the shields set up by the volatilizing of the coating materials used with coated electrodes, e.g. argon, helium, carbon monoxide, carbon dioxide or mixtures of these and various other gases, with or without entrained powders for stabilizing the arc. The cross-section of the sleeve may also take the form shown in Figs. 1 and 3.

Title: Improvements in or relating to apparatus for tipping and discharging railway wagons
IPC: B65G67/00
Filed: 1934-02-07
Abstract: 433,530. Tipping apparatus. PRESLAND, C. W., Dumsey Point, Shepperton-on-Thames. Feb. 7, 1934, No. 4026. [Class 78 (iv)] The L-shaped wagon-receiving cradle 1 of a tipping-apparatus is pivoted at 6<a> to side rods pivoted in turn to fixed points at 6b and is also connected pivotally at 10<a> to shorter camshaped links pivoted to other fixed points at 10<b>. The positioning of the pivots and the difference in length between the links causes the wagon to be tipped sideways as shown in dotted lines when hoisted by the cable 12 passing from drum 13 round the periphery of the cam-shaped links to fixed points on the cradle near the pivots 10<a>. Balance weights 14 are suspended by a cable 15 passing to drum 19 fixed on the winding-drum shaft. Cables 26, fixed to drums on the shaft 21, pass to the pivoted-arm wagon-securing structure 24. As the wagon commences to tip, it contacts with the structure 24 and moves it about its pivots so that the run of the cable 26 passes to the opposite side of the vertical line through the axis of the pulley 27 and thereupon the continued movement causes the cable 26 to be paid out against the action of the counterweights 14, which provide sufficient force to maintain the wagon on the rails. Various modifications are referred to, including the replacing of the cam-shaped links by straight links and the transfer of the winding-drums to, or use of guide sheaves in, an overhead position. In some cases the winding-gear may be replaced by toothed gearing driving toothed sectors mounted on the links at the pivots 6b, 10<b>. The cradle is provided with the usual tilting platform 3 and side support for the wagon.

Abstract: 977,777. Microwave ovens. J. LYONS & CO. Ltd. Jan. 31, 1963 [Feb. 2, 1962; Nov. 13, 1962], Nos. 4065/62 and 42834/62. Heading H5H. A radio-frequency oven comprises walls 5 defining an enclosure 6 for an article to be heated, a source of radio-frequency energy 11 and separate waveguides 12, 13 extending from source 11 to a point on each of two opposed walls of enclosure 6, radiation means at these points for radiating energy in mutually perpendicular planes into enclosure 6, and means for supporting an article within enclosure 6 so as to intercept energy radiated from the radiation means. As shown, the radiation means comprises slots 17, 18 arranged at right angles to each other to polarize the radiation. The means for supporting articles comprises shelves 8, 9 of glass or similar dielectric material. The electrical path lengths between source 11 and slots 17, 18 differ by an odd number of quarter wavelengths, conveniently one, so that the radiation from slots 17, 18 is 90 degrees out of phase. The height H of enclosure 6 is a whole number of wavelengths, conveniently one. Source 11 is a magnetron and dent 15 provides impedance matching. In a second embodiment (Fig. 3, not shown) the two waveguide paths are similar and symmetrical to prevent loss of power. Specification 977,776 is referred to.

Title: Improvements in or relating to fuel burners
IPC: F23D11/10
Filed: 1933-02-10
Abstract: 414,756. Vacuum apparatus; raising liquids by aerating ascending column. WILTSHIRE, W. F., 16, Birmingham Factory Centre, King's Norton, Birmingham. Feb. 10, 1933, Nos. 4153, 8819, and 25713. [Class 102 (ii).] The main fuel storage tank 38 of a liquid fuel burner 1 is connected to a closed subsidiary tank 39 by a fuel raising pipe 40 and an overflow pipe 41, both of which pipes have their upper ends approximately level with the burner fuel jet. The tank 39 is connected above and below the fuel level by pipes 43, 44 to the burner. When the burner is in operation a partial vacuum is produced in the tank 39 by the suction at the burner and fuel is drawn up the pipe 41 which is fitted with a number of non-return valves 42. The valves 42 above the oil level admit air to the fuel pipe, the aeration of the fuel reducing the vacuum needed. Separation of the fuel from the air takes place in the tank 39. A valve 45 allows air to enter the tank 39 if owing to the high fuel level in the tank insufficient air enters by the valves 42. In another arrangement, the tank 39 is at the same level and is arranged inside or in connection with the main fuel tank, the fuel level in which may be either above or below the burner, cocks being provided to prevent oil from flowing into the pipe 43 and to allow air to enter the burner air tube when the fuel level is high. In some cases the pressure in the warm fuel tank may be raised above that of the atmosphere by a connection to the pressure air supply to the burner. Fig. 10 shows a suitable construction of valve 42. The valve body 49 contains a sleeve 50 resting on the lower length of the pipe 40 and formed with a circumferential groove 50<a> which is connected by ducts 50b to the seating on which rests the valve member 51. The groove 50<a> is connected to the atmosphere through an adjustable needle valve 52 so that the valve member 51 in the closed position shuts off both air and oil. A stop 53 limits the upward movement of the member 51. Preferably, air is only admitted at the lowest valve 42 above the fuel level, ingress at the other valves being prevented by floats 60. In another construction the oil and air admission valves are separate.
