Title: Improvements in or relating to gas discharge devices such as cold-cathode tubes
Inventor: JEFFERSON SIDNEY
IPC: H01J9/395
Filed: 1953-07-03
Abstract: 748,906. Cold-cathode tubes. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. July 2, 1954 [July 3, 1953], No. 18489/53. Class 39 (1). A gas discharge device comprising an envelope and an electrode structure within said envelope has a tritium-containing element supported within said envelope so that it may be selectively heated by means outside the envelope so as to release the tritium into the envelope. The cold-cathode diode shown comprises a thimble-shaped anode 10 supported on wires 11 and a disc cathode 12 supported on wires 13. The tritium-containing element may be in the form of a fine wire of highly purified zirconium impregnated with tritium and provided with a coating of copper, or a ribbon of tungsten coated on one face with zirconium impregnated with tritium, folded in two along a longitudinal centre line with the coating inside and sealed along the three open edges, or a nickel tube filled with tritium and flattened at each end. Two alternative methods of supporting the element are shown. According to one method the element 3 is spot welded to the flattened ends of the legs of a nickel wire stirrup 6 spot welded to a wire 15 which is welded to a support wire 11. The loop formed by the stirrup 6 and element 3 is eddy current heated by means of a coil C located outside the envelope and supplied with alternating current. At red heat the element bursts or leaks sufficiently to release the tritium. Alternatively the element 7 is spot welded between an additional lead 16 and a support wire 11 and may then be heated to red heat or fused by passing a current through it. The released tritium is deposited on the electrode structure and the wall of the tube and to encourage deposition in the region of the main discharge gap a tantalum or zirconium wire 17 is spot welded across two electrode leads 11 and 13 and fused by passing a current therethrough prior to releasing the tritium. The resulting deposit 18 of tantalum or zirconium selectively absorbs the tritium when it is released into the envelope. Specifications 737,386 and 738,182 are referred to in the Provisional Specification.

Abstract: 457,645. Making wire fabrics. SPUHL, E., and SPUHL, J., 7, Lukasstrasse, St. Gall, Switzerland. July 3, 1936, No. 18534. [Class 83 (iv)] [See also Group XIV] In a machine for connecting mattress &c. springs by wire clips 14, Fig. 14, a tong member straddles adjacent springs to bring them beneath a pincer member for positioning a preferably sharpended clip over the springs. Mechanism then operates to close the clip, the point piercing the fabric. In use the clip takes the position to the right, Fig. 14. A clip is positioned in a groove of a wheel 13 rotated by ratchet 18 from a crank 19. At the bottom of its rotation the clip is grasped by holding arms 20 when a nose 37 of lever 35 operated by a cam 10 is removed from between the arms 20. The arms are then lowered by the cam 10 and a bell-crank 22. The springs S are inserted between a stationary tong member 39 and a movable member 41. When the arms 20 move downward to lower the clip a roller 45 swings the arm 41 to close the tongs and to bring the springs together. Levers 7 are then operated by cams 5 to move levers 28 to effect the closing of the clip. The springs may be tied by cords 49 fed through a hole in the member 39.

Abstract: 503,945. Photomechanical printing- surfaces. DULIK, K. July 9, 1937, No. 19117. Void. Convention date, July 10, 1936. [Class 98 (ii)] Printing plates or cylinders for intaglio printing with a doctor blade, are prepared from originals in which the shades of the picture are divided into lines and the half-tones and high lights into dots. The originals may be obtained by the use of a screen having lines alternately widened and constricted resembling a string of beads as shown in Fig. 1. This screen may be used in making screened negatives from which diapositives are produced or in preparing screened diapositives from unscreened negatives. Alternatively, the negatives or diapositives may be produced using a cross-line screen and a rhomboidal stop with the major diagonal parallel to one set of screen lines. In a further method, the negatives or diapositives are produced by exposure in contact with a cross-line screen using a row of lamps parallel to one set of screen lines or a single lamp moving parallel to one set of screen lines. The screens may be prepared by printing across line screen on a sensitive surface using a rhomboidal stop as above.

Hydrocarbons, distilling.-In the continuous treatment of crude oil for the production of light distillates with a minimum of cracking and the continuous cracking of the heavier bottoms separating therefrom to obtain a fuel oil residue of greater fluidity than the bottoms and additional light distillates, oil is pumped through a preheater comprising a bank B of tubes in the cooler part of a tubular oil heating furnace A, thence through a bank B<2> in a hotter portion of the same furnace and finally through a bank B<4> in the hottest part thereof to heat the oil rapidly to a cracking temperature and yet cause a minimum of cracking. The heater oil passes into a fractionating column D having off-takes D<1> - - D<5> and the bottoms remaining pass down a pipe D<6> to be pumped through a bank b of cracking tubes disposed in the furnace between the bands B and B<2>.

The cam grooves extend the full length of the sections and rotation of the inner section to the unclamped position is limited by abutment of the faces 21, 22 of the cams. Near the upper end 23 of the inner section I is fixed an annular bushing 24 in which is rotatably mounted a stud 26 to which is fastened one end 34 of the coil spring 31, the other end 32 of which is fastened to the annular bushing 24. A triangular extension 35 of the stud 26 carries three rollers 37 which ride on tracks 22 on the inside surface of the outer section 10 to prevent rotation of the stud 26. In assembling the leg the spring is tensioned so that it normally tends to rotate the section 11 anticlockwise relative to the section 10 into the clamping position. To prevent the inner section being completely withdrawn, a spring- pressed lever 38 on it has a nose 40 passing through a hole 41 in the inner section and adapted to engage a hole 44 in the outer section.

Filed: 1957-06-20
Abstract: N - (2 - pyrimidylsulphenyl) - morpholines are prepared by reacting an alkaline solution of a 2-mercaptopyrimidine with a N-halomorpholine.  The alkaline medium is preferably an aqueous or alcoholic solution of alkali or alkaline earth metal hydroxides. Suitable 2-mercaptopyrimidines are, for example, 2-mercapto-4-alkyl-, -4,5-dialkyl-, and -4,5,6-trialkylpyrimidines especially the 2-mercapto-4-methyl and 4,6-dimethyl derivatives, or also the corresponding aryl derivatives.  The preferred N-halomorpholines are the N-chloro- and N-bromo-morpholines.  The reaction is preferably carried out by gradually introducing an aqueous and/or alcoholic solution of an alkali metal salt of a 2-mercaptopyrimidine into a N-halomorpholine.  The products are vulcanization accelerators and also intermediates in the synthesis of pharmaceuticals.  In examples, N - (4 - methyl - 2 - pyrimidylsulphenyl) - morpholine is prepared by adding an aqueous or methanolic sodium hydroxide solution of 2-mercapto - 4 - methylpyrimidine to N - chloromorpholine.
