Filed: 1964-08-04
Abstract: 1,016,405. Coating wire. HOOKER CHEMICAL CORPORATION. Aug. 4, 1964 [Aug. 6, 1963], No. 31160/64. Heading B2B. [Also in Division Dl] A process for coating a wire comprises passing a wire through a halogenated hydrocarbon vapour zone into a hot coating composition comprised of film-forming ingredients and a halogenated hydrocarbon solvent for at least the major portion of the film-forming ingredients, the coating composition being at a temperature below the boiling point of the solvent, removing the wire from the coating composition and again passing it through the halogenated hydrocarbon vapour zone, repeating the above procedure so as to form on the wire successive films of the coating composition, and subjecting the wire to heating between successive passages through the coating composition, thereby reducing the solubility of the film of coating composition on the wire. Specified film-forming ingredients are alkyd resins, phenolic resins, epoxy resins and polyurethane resins. Specified halogenated hydrocarbon solvents are trichloroethylene, carbon tetrachloride, perchloroethylene, the trichloroethanes, the tetrachloroethanes, methylene chloride, ethylene dichloride, ethylidene chloride, the dichlorotetrafluoroethanes, the trichlorotrifluoroethanes, the tricholrodifluoroethanes, the tetrachlorodifluoroethanes, the fluorotrichloroethanes, the fluorotetrachloroethanes, methyltrichloroethylene, 1,2-dichloropropane, 1,2-dichloropropene, 1,1,2-trichloropropane, ethyltrichloroethylene, mixtures thereof and other halogen analogs of the above. The temperature of the coating bath may be maintained between 40 ‹C. and 50 ‹C. below the boiling point of the solvent but is preferably only slightly below this point, e.g. 2-25 ‹C. As shown, the wire 30 to be coated passes in flattened-helicoidal form between parallel grooved rotatable drums 28, 30 situated in a coating tank 11 and a curing section 32, respectively. The upper edge of the tank 11 is surrounded by a peripheral trough 23 to catch solvent condensed on cooling coils 24. A peripheral jacket 25 is supplied with a coolant to cool the contents of the trough 23. The coils 24, the jacket 25 and the trough 23 are positioned so that only a relatively small vapour zone is formed between the upper surface of the coating in the tank 11 and the lowermost coil 24. Heat lamps 38 are provided in an oven section 39 of the section 32. Substantially all of the solvent in the film of the coating composition, which was not flashed off in the vapour zone, is removed in the area between the vapour zone and the section 32. This area may be open to the atmosphere, as shown, or may be enclosed and contain air or a non-reactive gas, e.g. nitrogen, or may be under vacuum. A system for maintaining the proportion of the ingredients of the coating composition in the tank 11 constant is described, Fig. 2 (not shown), (see Division Dl).

Abstract: 219,236. Uehling, F. F. Dec. 12, 1923. Testing heating, illuminating, and motivepower gases.-In an apparatus for estimating and recording the combustible constituents of a gaseous mixture, the gas is passed through a chamber having an inlet and an outlet, which are both heated, and the variation in the pressure of the gas in the chamber due to the prior combustible constituents is indicated on a suitable gauge. The inlet and the outlet are :constructed so as to offer resistance to the flow of gas, and means are provided for regulating the flow so that in the absence of a combustible constituent there is always a constant pressure-difference between the inlet and the outlet. The chamber 1 has a restricted inlet A and a restricted' outlet B, these parts consisting, in the apparatus shown, of platinum capillary tubes protected from atmospheric influences bv insulated casings 31, 32. The tubes A, B are electrically heated from a battery 4, the current passing by way of pipe 3, tube B, chamber 1, tube A, and rheostat 8; the pipes 3, 2 are electrically insulated as at 6. The temperature to which the tubes are heated is above that required for the complete combustion of combustible constituents, and' the length of the tubes is such that combustion is completed during passage of the gas through the inlet A. Gas is drawn through the apparatus by an aspirator 21, and to ensure a normally constant pressure-difference between the tubes A, B a regulating device is provided comprising tubes 24 - - 26 immersed in water to different depths as shown in the Figure. The tube 26 is open to the atmosphere and serves to compensate for any fluctuations in the capacity of the aspirator, which is arranged to draw gas through all three tubes so that the normal pressure difference between the pipes 2, 3 is represented by the head b, c. Gas, previously filtered and dried, enters the apparatus through an orifice 20, the combustible constituents are ignited in the tube A, and the corresponding change in pressure in the chamber 1 is duly recorded by the manometer 10 and the gauge 11.

Abstract: 644,617. Supply systems for welding-arcs. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Nov. 28, 1947, No. 31529. Convention date, Nov. 30, 1946. [Class 38 (iv)] To reduce the open circuit voltage necessary for stable operation of an A.C. welding arc, the welding circuit 11 is shunted by a condenser 22 having a capacity of from 50 to 250 microfarads and forming with a reactor 21 an oscillatory circuit having a natural frequency of about 600 to 1000 cycles per second which is shocked into oscillation to re-strike the arc when the current in the welding circuit passes through zero. Additional and variable inductance, not carrying the welding current, may be included in series with the condenser to allow further adjustment of the natural frequency of the oscillatory circuit. The arc current may be controlled by a further reactor 20. Using a 60-cycle per second supply wave, an open circuit voltage of 55-65 volts and a welding current of 105 amperes, the condenser should supply one watt-second of energy to the welding circuit at a peak current of 200 amperes each half cycle of the supply wave, whilst its charging time should be about 4 per cent of onehalf cycle of the. supply wave.

Title: Improvements in or relating to die-casting
Inventor: CARLSEN JON ERIK MARIUS
IPC: B22D18/04
Filed: 1967-07-08
Abstract: 1,235,109. Casting-machines. J. E. M. CARLSEN. 7 Oct., 1968 [8 July, 1967], No. 31529/67. Heading B3F. In a low-pressure die-casting machine in which molten metal is forced upwards from a furnace 40 into a die cavity (21) through a feed tube 16, 18 extending below the melt surface level, the pressure of air (or inert gas in the case of molten Mg) applied to the melt surface to raise the metal is controlled to maintain the level of metal, in the tube, above the level in the furnace between successive casting operations. The purpose is to reduce movement of the metal in the feed tube 16, 18 and turbulence in the furnace 40. Compressed air from an inlet 30, or (in the ghost line modification) inert gas returned by a line 67, passes to the furnace 40 when a valve 37 is opened. This valve is opened by gas from a bypass 50, 60 (controlled by a valve 53 operated by an electric circuit including a timer switch 54) for an interval which allows the die cavity (21) to be filled and the metal therein solidified. To allow the metal level in the feed tube to fall to about the junction of its upper and lower sections 18 and 16 before opening the die elements (20, 20a) to extract the casting, a valve 42 is opened by gas from the line 60 (with the valve 37 closed) so that some gas from the furnace 40 passes into a receiver 41. The pressure of the gas in the furnace 40 and the receiver is determined by the available receiver-volume, possibly adjusted by altering the volume of a body of liquid in the receiver. When the casting has been extracted and the die reclosed, the valve 42 is closed and the valve 37 re-opened to refill the die while the receiver 41 is exhausted to atmosphere or (if inert gas is used) passed by a pump 63 to a reservoir 64, through a normally closed valve 44. A microswitch 56 in the electric circuit is operated by mechanism of the die support (22) so that the valve 53 cannot operate to start the cycle until the die is properly closed and a safety switch 61 ensures that the die is not opened while under pressure from the metal.
