Title: Process for producing a carbon black
IPC: C09C1/50
Filed: 1949-04-20
Abstract: <PICT:0661057/III/1> Liquid hydrocarbon, e.g. catalytic process distillate having an A.P.I. gravity 21-23, which may be preheated to 300 DEG -600 DEG F, is supplied through tube 13 and unheated hydrocarbon gas, say natural or refinery gas, or air is injected through tube 10 and the resultant suspension passes into combustion chamber 18 of cylindrical refractory-lined furnace 12.  Air is injected through spaced ports 14 preferably in a direction tangential to the inner wall of the furnace so that partial combustion in the resulting turbulent admixture raises the temperature of the gases to say 1200 DEG -1600 DEG F during their passage in say 0.06-0.12 sec. through chamber 18, which is preferably 1/6th of the length of the furnace.  The gases pass through orifice in collar 17 and expand into reaction zone 19, while further combustion is effected and wherein the temperature falls from 2650 DEG -2500 DEG F during 0.14-0.28 sec., and pass to flue 20 wherein the temperature falls to 2150 DEG F in 0.18-0.36 sec.  The resultant gas mixture may be cooled to 600 DEG F by water spray, and then passes to a carbon black collecting apparatus.  The orifice in collar 17 should have a cross-sectional area equal to 1/7th of the cross-sectional area of the furnace so that the pressure in chamber 18 is 4-7.5 inches of water while that in zone 19 is 0.6-2 inches of water.

Title: Improvements in or relating to plastic welding by high frequency dielectric heating
Inventor: WILKINSON WILLIAM DINSDALE
IPC: B29C65/04
Filed: 1958-04-02
Abstract: 885,820. Seaming non-metallic sheet materials. RADYNE Ltd. July 1. 1959 [April 2, 1958], No. 10626/58. Class 42 (1). [Also in Group XI] In a method of welding a sheet of thermoplastic material to a thermoplastic layer of a laminate in which a metal layer adheres to the thermoplastic layer, the laminate and the sheet are superposed and pressed together where the weld is to be made, between the metal layer of the laminate and a further electrode having highfrequency energy applied between them to heat the thermoplastic sheets dielectrically. Where two laminates of metal and plastic are to be welded together each metal layer acts as an electrode, the plastic sheets being welded together in their overlapping areas. The method may be applied to the lining of metal cans with thermoplastic material by seaming the material along the edges of the can before the ends are applied. A metal and plastic laminate is formed into a cylindrical shape with its plastic face inwards, the marginal portions of the two adjacent edges are bent and rolled together so that the plastic layer of one marginal portion comes into contact with the plastic lining of the cylinder wall adjacent the other marginal portion. A bar electrode is pressed against the interior of the cylinder wall at the site of the seam and high-frequency energy is applied between the electrode and the metal layer of the cylinder wall, the adjacent plastic layers being heated dielectrically. If desired a plastic filler string may be placed in the joint of the can. Similar plastic and metal laminated end portions may be applied to the can, the plastic layer being bonded by means of an induction heating work coil used to heat the metal wall of the can.

Title: Improvements in the production of inflated hollow articles
IPC: B29C49/46
Filed: 1940-06-25
Abstract: 538,329. Hollow articles; balls. DUNLOP RUBBER CO., Ltd., TWISS, D. F., and EVERETT, R. M. June 25, 1940, No. 10857. [Class 132 (ii)] [Also in Group V] Relates to a process for inflating balls or other hollow articles with nitrogen produced by chemical reaction between an ammonium salt and a nitrite of an alkali metal and consists in eliminating gaseous atmospheric oxygen (entrapped when the ball is sealed prior to vulcanization) by effecting the reaction under acidic conditions in the presence of an excess of the nitrite. For example, prior to sealing and vulcanizing, ammonium chloride, sodium nitrite, benzoic or salicylic acid and water may be introduced into the ball. The reaction resulting from the heat of vulcanization causes evolution of nitrogen and absorption of substantially all the entrapped oxygen. The acidic condition may be provided by ammonium salts possessing in themselves, or as impurities, the desired acidic qualities.

Class 38(5) A gas-blast switch has an arc chute with two blast passages 15, 16 and a blast "divider" 19 with a nozzle 23 for directing a high intensity stream of gas into the passage 15 to interrupt relatively high currents, and a nozzle 24 for directing a lower intensity stream of gas into the passage 16 for interrupting relatively low currents. The nozzle 23 is of substantially circular cross section and may be larger than the nozzle 24, which is of oblong cross-section and extends for substantially the full width of the passage 16. The blast divider also has a funnel-shaped portion 22 communicating with a gas supply conduit 13 and housing the fixed and movable contacts. 7, 8. Each blast passage 15. 16 may contain an electrode 39. 41 which extends across substantially the full width of the-passage, the electrode 39 being connected by a resistor 40 to the fixed contacts 7.

When the arc comes into contact with the electrode 39, a portion of the are is shunted by the resistor 40 and extinguished. The portion of the arc in series with the resistor may be extended into the passage 16 as the contact separation increases and there extinguished by the lower intensity stream of blast gas through the nozzle 24.

Printing-apparatus.-An apparatus for copying written or printed surfaces, designs, pictures, &c. comprises a casing having an open mouth 11, Fig. 1, in which is journaled a transparent or translucent roller 12, a film 15 passing from a Spool. 13 and between the roller and the surface 20 to be copied to a spool 14. The apparatus is traversed over the surface 20, and light from electric lamps 17 passes through the roller and film to the surface 20, whence it is reflected to a greater or less extent back into the film. In order to rotate the roller 12 at a predetermined speed, an arm 50, Fig. 6, on the shaft of a gear sector 55 is moved along a scale 57 and then released. A spring 53 suddenly returns the sector 55, which gears with a pinion 56 on the shaft of a fly-wheel 45, which is connected to the roller 12. The pinion 56 is moved into correct position for meshing by a spring finger 66 on a lever 62 provided with an operating-stud 65, the lever being returned to its normal position by a cam-surface 68 on the arm 50 coming into contact with the stud 65. The lamps 17 are mounted in a casing having a cap 69 and a plate 71 of insulating-material, the lamp casings 73, Fig. 3, being connected by a conductor 80. Two lamp contacts 72 are connected by a conductor 81 to the outer casing of the apparatus, the remaining contacts being connected to a terminal 83 connected to one of the terminals of a battery.
