Abstract: <PICT:0953137/C3/1> <PICT:0953137/C3/2> A tubular hydrocarbon cracking reactor in a furnace comprises first and second sections, the first section (2) being substantially circular in cross-section and the second (3) having one axis longer than the other, the second section being positioned so that its broader side(s) face(s) the furnace heating means (7).  In a preferred embodiment the second section 3 is substantially rectangular (see Fig. 4); cross-pieces 8 connect the broad sides and serve to support and maintain the cross-sectional profile and to cause turbulent flow.  Preferably the ratio of lengths of the first to second sections is 1 : 1-1 : 2, of cross-sectional areas is 1 : 1-3 : 1 and of surface area/capacity ratios is 1 : 2-1 : 5.  Acetylene and ethylene can be produced in the apparatus by pyrolysis of gaseous and/or liquid hydrocarbons with recycled residual gas and in the presence of an inert diluent such as steam. Cracking to olefines occurs in the first section and to acetylene in the second.

Abstract: 506,151. Cutting-out plastic material. UNITED STATES RUBBER PRODUCTS, Inc. Dec. 8, 1938, No. 35787. Convention date, Dec. 11, 1937. [Class 87 (ii)] Blanks, such as shoe parts, are formed from continuous plastic material, such as rubber, by partially severing the blanks leaving a continuous strip of scrap material, disposing and pressing the material on mats on a conveyer, and moving the scrap out of the path of the mats leaving the blanks adhering to the mats. The rubber &c. is sheeted in a calender 2 and the sheet 1 passes through a cooling tank 5 to a cutting press 8 in which a lower platen 9 presses the sheet 1 against the upper platen 11 which carries cutting blades 10. The blades 10, Fig. 3, have notches 12 which leave small strips joining the severed blanks to the scrap material. The sheet 1 then passes to a conveyer 13<1> where flexible mats 14 are introduced under the sheet. An upper conveyer 16 presses the sheet on to the mats and carries the continuous scrap back to the calender 2 leaving the blanks 18 adhering to the mats. A second conveyer 19 may be provided to press the blanks on the mats.

[Class 20 (iv).] A corrosion-proof tie member for attaching wall or roofing sheets to the supporting structure comprises a flexible metal core 14, a tubular textile member 15 enveloping the said core, and an asphalt or like bituminous outer coating 17, the ends being covered by an asphalt sealing member 21. The strip 14, which may have a preliminary asphalt coating, is first fed through a braiding machine in which the tubular member 15 is formed, after which the whole is subjected to the action of an asphalt bath at about 300‹ F. until the textile member 15 is saturated. The outer coating 17, preferably of a high-temperature asphalt containing stearin pitch, is then applied, and the strip is cut up into suitable lengths to form the tie members. Holes 19 are then formed to accommodate the securing bolts, the strips are suitably bent, and finally the ends are dipped in an asphalt bath to form the sealing pieces 21.

Labels 12 are removed from a magazine 13 by adhesion segments 1 each pivoted on a rotary carrier 2 by means of a gear-wheel 5 turned by a toothed segment 8 under cam control, so that on approaching the magazine 13 the segments 1 pivot forwards, i.e. in the direction of movement of the carrier, and rock rearwardly on the labels as they pick them up. The toothed segment 8 is formed on one end of a bell-crank lever 6 carrying a roller 9 guided by a track 10. The segments 1 are gummed by a rotating roller 11. Grippers 14 on a rotary conveyer 15 remove the labels from the segments 1, the conveyer 15 attaching the labels to articles, e.g. bottles. In a modification, Fig. 10 (not shown), the conveyer (15) attaches labels to articles (16) carried on a conveyer belt (18), the labels being supplied alternately from a pair of rotary carriers. Again, the segments 1 may pick up the labels by suction, carry them past a gumming roller and attach them directly to the articles; or they may pick up labels coated with thermoplastic, the gumming roller being replaced by a heating, device. The grippers 14 may be replaced by suction elements.

Abstract: 819,146. Perforating sheet materials. STANDARD TELEPHONES & CABLES Ltd. Nov. 26, 1956, No. 36031/56. Class 31 (2). [Also in Groups XXII and XL (b)] A process for producing acoustic impedance material consists in piercing solid material 2 to produce an array of closely-spaced very small holes or slots, Fig. 3, of controlled dimensions by means of a corresponding array of coplanar needle points or chisel edges up to a predetermined cross-sectional area of their taper.

Abstract: 1308508 Electromagnetic switches ARROWHART Inc 27 July 1970 [28 July 1969] 36262/70 Heading H1N Two electromagnetic contactors 10, 12 are interlocked, so that only one may be operated at a time, by an assembly having pins 40 slidable axially in holes in the contactor housings and movable into the paths of projections 25 of the armatures of the contactors. When a contactor armature 22 is attracted to its electromagnet a cam member 23 on the armature engages a roller 44 to move the interlock assembly away from the operated contactor so that the respective pins move under projections 25 of the other armature. On de-energization springs 46 restore the interlock assembly to its midposition. If the second contactor is energized its projections 25 clamp the pins 40 under them so that both contactors need to be de-energized before the second contactor can be operated.

A thin film of metal getter material is deposited within a discharge tube envelope by evaporation in the presence of a gas at a pressure sufficient to limit the mean free path of the getter metal atoms to a distance comparable with or less than the distance between the getter evaporation source and the relevant portion of the envelope whereby, in a cathoderay tube, for example, the production of an unduly thick getter layer in the centre portion of the screen may be avoided. The preferred gas is nitrogen, at a pressure between 5 x 10<SP>-2</SP> and 1 x 10<SP>-3</SP> torr, introduced either as such before sealing off, or as a compound which can be disassociated to yield nitrogen at a temperature below that at which the getter evaporates. The nitrogen compound, of which suitable examples are given, may be either physically separated from the getter container, or mixed with the getter material therein, or the getter container itself may be nitrogenated. In an example, a barium film is deposited in a cathode-ray tube from a getter mixture of barium/aluminium alloy and nickel, in the presence of nitrogen derived from powdered iron nitride; a baffle prevents backward deposition of the barium on the electron gun structure, and the free nitrogen is itself finally removed by the gettering action of the film.
