Title: Improvements relating to the treatment of sewage and other waste liquors
IPC: C02F3/18
Filed: 1934-10-06
Abstract: 445,352. Treating sewage &c. KESSENER, H. J. N. H., 1, J. P. Coen Straat, The Hague. Oct. 6, 1934, No. 28669. [Class 111] An aerator for use in the treatment of sewage &c. comprises a rotary shaft c from which project a number of strips b which are sufficiently resilient to become bent while being drawn through liquid and to resume their unrestrained form on leaving the liquid. The strips are so arranged on the shaft that when the aerator is immersed to less than half its diameter in liquid, the acute angle made by each strip to the horizontal as the strip enters the liquid is less than the angle between the horizontal and a line passing through the centre of the shaft and the outer end.of the strip. The aerator is mounted in a tank, and to prevent air that has been beaten into the liquid from escaping too rapidly a plate e is fixed horizontally near the aerator and below the surface of the liquid as shown in Fig. 2. An air diffuser f may be provided as shown in Fig. 4, and also a baffle g to assist circulation of the liquid. Fig. 5 shows an, installation for the aeration of sewage &c. in' which a constant flow of the liquid under treatment is maintained. The liquid is admitted through a pipe hand inlet i into tanks j, k provided with aerators as described above. The tank k discharges into a settling tank l provided with an effluent chamber m and a sludge return conduit n from which sludge can be lifted by a screw or wheel &c. o and returned into the inlet pipe h. The sludge lifter o and the aerators in the tanks may be driven by a motor p.

Abstract: 154,438. Chassis Construction Co., and Laurence, L. Nov. 19, 1919. No Patent granted (Sealing fee not paid). Axles for motor and other vehicles are formed of sheet metal with the middle and ends of channel section. The sheet metal is pressed to form continuous upper and lower flanges C, D, and with end flanges E at the jaws round which at F and G the sheet metal may extend. Shaped blocks H are then inserted in the jaw parts and the open side of each axle end is enclosed by a jaw-shaped plate J united to the axle by welding or like operation. The blocks H are drilled after being placed in position, for the reception of the steering-pivots.

Title: Multiple arc welding
IPC: B23K9/173
Filed: 1958-09-08
Abstract: 903,253. Welding by fusion. AIR REDUCTION CO. Inc. Sept. 8, 1958 [Sept. 16, 1957], No. 28766/58. Class 83 (4). In electric arc welding apparatus in which two series connected high current density self regulating arcs are formed between continuously fed electrodes and a common workpiece, control devices are provided in the feeding arrangements of each electrode to interrupt the feed of an electrode when it makes electrical contact with the workpiece. Two like D.C. generators 13, 30 are connected in series with electrodes fed by mechanisms 6, 22 to inert gas shielded guns 3, 4 mounted on a common frame 1 movable relative to a workpiece 2. When the welding current is connected up by contactors 15, 32, relays 37, 41 are operated to actuate clutches 25, 26 to couple a common motor M or two synchronized motors to the feed mechanisms 6, 22. When an electrode, say that passing through the gun 3 contacts the workpiece 2, the relay 37 is shunted down and the feed mechanism 6 is disconnected to stop the feed. When the second electrode contacts the workpiece 2, relay 41 is de-energized and the feed mechanism 22 stops feeding the second electrode. The combined voltage of the generators 13, 30 strikes arcs between the electrodes and the workpiece, whereupon the relays 37, 41 re-operate and both electrodes are fed. In a modification, one generator supplies the welding current. In either case the electrode fed to the arc of straight polarity is treated with an emissive agent as described in Specification 738,284. If an A.C. welding supply is used both electrodes are treated with an emissive agent as described in Specification 731,836. Specifications 687,666 and 713,507 also are referred to.

[Also in Group XVII] The mouth of a bag made of relatively thick thermoplastic sheet material, e.g. sheet polythene having a thickness of 0.01-0.03 inch, is sealed by applying pressure to its opposed walls 1 and 2 and generating the required heat by passing an electric current, e.g. from a 12 or 24 volt battery, through a wire 3 which is disposed between the walls and subsequently remains in position for use as a rip wire and/or for resealing the bag mouth after the walls 1 and 2 have been separated. The wire 3 may be incorporated in the bag during manufacture as by attaching it to the inside of the wall 1 by a covering layer or pieces of thin thermoplastic sheet material 4 secured to the wall by adhesive or the application of heat.

Title: Improvements in or relating to the Manufacture of Flat Glass.
IPC: C03B18/14
Filed: 1965-07-09
Abstract: 1,151,853. Flat glass. PILKINGTON BROS. Ltd., D. G. LOUKES, and G. NIGHTINGALE. 8 July, 1966 [9 July, 1965], No. 29288/65. Heading C1M. A method of manufacturing flat glass comprising separately contacting the surfaces of the glass with bodies of molten electrically conductive material isolating the molten bodies from each other and passing a controlled electric current through the glass between the isolated bodies thereby modifying the surface constitution of the glass particularly so that metal enters the surface layer when molten metals are used. The molten electrically conductive material is confined on the upper surface of the glass by forming the margins of the glass ribbon as ridges thus laterally containing the molten pool. The forward and rearward movement of the molten pool is prevented by carbon barriers. In one embodiment the electric current is passed through the glass in a direction such that the molten pool acts as an anode and the top surface of the glass is modified. By reversing the electrode leads and including other metals in the bath, the bottom surface of the glass may be modified. In another embodiment both surfaces of the glass may be modified simultaneously by having two molten pools of electrically conducting material confined on the upper surface of the glass and separated by a distance such that the pools are electrically isolated from one another, passing electric current through the glass between the molten metal surface and the pools of molten metal in a direction such that one pool acts as an anode and the other as a cathode with respect to the molten metal surface, and an apparatus for use in such a process comprising a tank structure containing a bath of molten metal 10, means for delivering glass at a controlled rate to the bath and for advancing the glass along the bath as a layer of molten glass in ribbon form, thermal regulators 23 and 24 for controlling the viscosity of the glass so as to ensure that the glass is gradually cooled as it is advanced, means for maintaining a pool of molten material 39 on top of the glass and for preventing forward movement of the pool with the glass, electrodes arranged to dip into the pool of molten material and into the bath of molten metal, an electric current supply circuit connected to said electrodes, and edge shaping means 31 and 32 mounted relative to the tank side walls 7 for shaping the margins 36 of the ribbon of glass 37 so that the ribbon assumes a shallow trough-like formation, and means for maintaining the pool of molten material in said trough. The bath is preferably molten tin or a tin alloy but may be lead or bismuth or an alloy thereof. The electrically conducting molten pool may be molten tin, lead or bismuth, an alloy of any of these with other metals (many specified) or a molten salt. The lead and bismuth alloys may be used to give colouring additions to the surface.
