Abstract: 1,209,660. Electro-phoretic painting. GES: FUR ELEKTROCHEMISCHE MATERIALBESCHICHTUNG m.b.H. [trading as E.C.M. GES: FOR ELEKTROCHEMISCHE MATERIALBESCHICHTUNG m.b.H.K.G.]. Dec. 23, 1968 [Jan.17, 1968], No.61214/68. Heading C7B. An organic coating is electro-phoretically deposited on a conducting article, e.g. of Al, Fe, steel or with Au-plated surface connected as anode or cathode in an aqueous dispersion of a partly or completely reacted plastics material, adjusted to an electrical conductivity of 5, 00 to 100, 000 micro-mho/cm, to which has been added one or more anionic, cationic or amphoteric organic compounds having surface active properties and capable of forming a passive layer on the article, which develop an electrical resistance on the article within 25 seconds after the current density peak to reduce the density below 20% of the peak. Examples of organic compounds are alkali metal and amine soaps, alkyl and aryl and alkylaryl sulphonates, alkyl sulphates, alkali metal and ammonium salts and esters of sulphosuccinic acids and of sulphuric acid esters of castor oil, fatty acid condensates, casein, gelatine, lactalbumin, zein and gum arabic. Suitable dissociating substances for adjusting the required conductivity include soluble hydroxides (e.g. NaOH) carbonates (e.g. Na2 CO3), phosphates, chromates, halides (e.g. KF), cyanides (e.g. KCN), and salts of mono, di-, or polycarboxylic acids. Suitable plastics materials include polyalkylenes, polystyrenes, styrene copolymers, polyvinyl (idene) chloride, polyvinyl-actuates, -ethers and -carbazoles, F-containing polymers, polyacrylates, polyesters, alkyd resins, polyamides, polyamines, polyurethanes, polycarbonates, epoxy resins, formaldehyde resins and silicone resins. The plastics may still contain carboxyl, carbonyl, hydroxyl, amino or epoxide reactive groups. The dispersion may also contain hydrazine and peroxides as acceptors for oxygen and hydrogen respectively, pigments and/or dyestuffs. Powdered plastics material, e.g. a styrene-acrylonitrile copolymer of particle size 0À2 to 10 microns, may be used in making the dispersions, which may be adjusted to pH 12 with triethylamine. A polyol e.g. triglycol may be added to increase the B.P. of the dispersion. Diphenoxyethylformal or dibutylphthalate may be included as a plasticizer. The counterelectrode, e.g. cathode of 18 Cr-8Ni steel, may be the bath tank. The process is suitable for continuously coating strip, tubing or wire. The organic coating may be cured by baking at 80-200‹ C or treatment with electronic rays.

Abstract: 632,290. Ticket-issuing machines. KOOPERATIVA FORBUNDET FORENING, U.P.A. May 18, 1945, No. 12547. Convention date, July 18, 1944. [Class 106 (iii)] A ticket printing machine of the kind in which the clichÚs intended for printing the tickets are carried by turnably-mounted members which are adapted during the working stroke of the machine to be moved from an inactive to an active position and to co-operate in the last-mentioned position with a cardboard strip advanced and cut-off in the machine as well as with a counting mechanism forming part of the machine, is characterized by the fact that the members carrying the clichÚs are divided into two magazines counterbalancing each other and adjustable into various positions, the machine being further provided with a selecting-device which makes it possible beforehand to select that magazine from which, during the working stroke of the machine, a cliche member is to be moved into active position. In the embodiment described, two magazines or frames 1, Fig. 3, are vertically slidable on bars 8 and 10, and each contains a plurality of arms 2 mounted on a vertical shaft 3. Each arm comprises a stepped plate 6 for co-operating with a register, and a clichÚ 5 for co-operation with ticket-printing mechanism when the arm is brought to the operative position. The frames 1 are positioned vertically under the control of a hand wheel 23 which, through gears 25, 26, turns a pinion 28 which is in engagement with racks 29 fixed to each magazine. Since the magazines I move in opposite directions they balance each other. In this manner the arm 2 for printing the desired ticket is brought opposite the operative position by observing indicator drums 24 on the hand wheel shaft. The magazine containing the required arm 2 is selected by movement of a lever 12 (see also Fig. 1) which moves a slide 15 having an oblique slot 16 co-operating with a pin 17 on a longitudinally-slidable bar 18. Members 19 on this bar engage, and move longitudinally, pins 21, engaging one or the other with a notch in one of two slides 30. The pins 21 slide in the U-shaped ends of vertical levers 22 rocked by a cam 33, so that the slide 30 which is engaged by a pin 21 is moved longitudinally and, since its hooked end 31 engages a notch 7 in the selected arm 2, this arm is turned about the shaft 3 and its clichÚ 5 and stepped plate 6 are brought into the operative position. To start the machine, a key 67 is depressed, and through a link 68 a pawl 69 is disengaged from a toothed wheel 70 allowing an electric motor 102 to drive, through this gear a cam-shaft 66 controlling the various machine operations.

Abstract: 635,542. Controlling gas burners. DENBERG, T. F. VAN., and SELBY, J. July 31, 1945, No. 19628. [Class 75 (i)] [Also in Group XXIX] Permanent-magnet safety control mechanism applicable to gas burners comprises relatively movable permanent magnet and keeper members one of which is movable with a valve biased towards its closed position and held open against such bias by attraction between the magnetic members when these members are brought into contact, the valve being permitted to close under the,action of its bias upon separation of the magnetic members by a temperature-responsive device when the burner flame is extinguished. As shown, a main burner 10, connected to a pipe 11, is supplied with gas frdm a pipe 12 controlled by a main valve 21 whilst a pilot burner 14 is supplied through a pipe 47 and a pilot valve 43. A temperature-responsive device comprising a tube 42 of a material expansible by heat, e.g. stainless steel and a relatively non-expansible member 50, e.g., of silica, porcelain, &c. within the tube is heated by the pilot burner. The main valve 21, loaded by a spring 24, and carried in a body 19 removable as a unit from the valve casing 13, has a stem 22 for engagement with a push button 37 for opening the valve whilst a piston valve 25 moves with the push button to close ports 32 in the body 19 when the button is depressed. As the main valve is opened, it engages a stem 44 of the pilot valve which opens against a spring 53, movement of the pilot valve being arrested by a rod 52, made of material similar to that of the tube 42, the main valve being in a position in which a small gap exists in armature or keeper 20 thereon and a fixed permanent magnet 35. In this position, the magnetic attraction between the parts 20, 35 is insufficient to hold the valve 21 open should the button 37 be released, but if the pilot burner is ignited the temperature-responsive device allows the pilot valve to move to the right and the members 20, 35 to come into contact to hold the valve 21 open, when the button 37 may be released to uncover the ports 32 and pass gas to the main burner. In the event of the burners being extinguished, the stem 44 of the pilot valve pushes apart the parts 20, 35, whereupon the main and pilot valves close under the action of their springs. Means is described whereby a dial indicator is employed for adjusting the amount by which the stem 44 projects beyond the face of the magnet 35 during initial assembly and adjustment.
