Patent GB-132869-A (GB)
IPC: F23D14/46
Abstract: 132,869. Smith, E. H. Sept. 24, 1918. Pilot jets. - A welding blowpipe burner has a pilotlight tip 21 arranged a substantial distance to the rear of the burner tip 14 and adapted, on the gas supply to the pilot-light tip being temporarily increased, to project an igniting-flame so as to intersect the gaseous stream issuing from the burner tip. Gas is supplied to the pilot-light tip through an annular passage 19 between an inner tube 5 conveying gas to the burner tip and an outer tube 18, the supply being controlled by a valve 24 working in the end of a port 22. The valve screws into a spring-pressed disk 25 having ports which, when the valve is not screwed down, permit of the passage of a small quantity of gas sufficient to keep a small pilot-light burning. The valve and disk may be raised, against the pressure of the spring 28, by a lever 31 actuated by the thumb of the operator. This allows of the passage of an increased quantity of gas, so that the pilot.flame is elongated and projected into proximity with the burner tip. On the lever 31 being released, the pilot-light resumes its normal dimensions. The gas may be cut off from the pilot-light tip by screwing down the valve 24.

Title: Improvements in distributors for routeing electrical impulses
IPC: G06F5/01
Filed: 1945-02-15
Abstract: 601,149. Thermionic distributers. NATlONAL CASH REGISTER CO. Feb. 15, 1945, No. 13674/47. Convention date, Dec. 27, 1943. Divided out of 601,122, [Group XIX]. [Class 40 (iii)] A distributing network for routing impulses arriving at any one of a number of input terminals 108 ... 113 to any selected one of a series of output terminals 1600, 1630, 1640, 1650, 1660, 1670, 1680 comprises electricdischarge tubes arranged in columns which are primed one column at a time so that an incoming impulse, although applied to several tubes, operates only one (that in the primed column) to send an impulse to the desired output terminal. The device is shown as embodied in the multiplying machine described in Specification 601,122. The tubes are gasfilled and arranged to be self-extinguishing. The first column 1840, 2200, 2220, 2240 is primed when potential is applied to a priming conductor 2260 connected to the grids of these tubes and energized when a control tube, not shown in Fig. 1, is fired as described in the said Specification. An incoming impulse arriving at an input terminal, e.g. 108, is applied to the grids of a row of tubes 1810, 1820, 1830, 1840, but only the primed tube 1840 will fire to produce an impulse at the output terminal 1650. The control tube is in due course extinguished and a second control tube fired as described in the said Specification, the priming potential being thus removed from the priming conductor 2260 and applied to a second priming conductor 2250 to prime the second column of tubes 1830, 2190, 2210, 2230, whereby an impulse arriving at input terminal 108 will now fire the tube 1830 to give an impulse at output terminal 1640. The remaining columns are later primed in turn. The conductors leading to the output terminals are connected diagonally across the network as shown. Specification 593,464, [Group XIX], also is referred to.

Abstract: 587,173. Electrolysis. IGRANIC ELECTRIC CO., Ltd. July 18, 1944, No. 13746. Convention date, July 28, 1943. [Class 41] [Also in Group XXII] A metal powder is produced in flake form by deposition electrolytically on a cathode and continuously loosening the deposit as it forms. An earthenware barrel 5 containing 40 per cent. silver nitrate solution at 90‹ F., slightly acid with nitric acid, is freely supported by a squareended shaft 11 carried in a fixed bracket 12. The anode comprises a mass of silver balls 23 within a fixed perforated container 14 of synthetic resin which is suspended within the barrel 5 by a copper member 16a to which one of the balls 23 is electrically connected by a copper chain 24, the other end of the member 16a being forked to pass over a pin 19 so that it is easily removable from a copper bracket 17 to which it is held by ferrules 18. The cathode comprises polished stainless steel balls 31, of 5/16 inch diameter, and a stainless steel connector 32a, insulated with paint or enamel 32c over part of its length, and fixed to a copper member 33a carried by a bracket 17 in a similar manner to the anode. The brackets 17 lie one behind the other and are insulated from the bracket 12. When the shaft 11 is rotated at 60 r.p.m. and 12 volts is applied to terminals 26 a thin film of silver is precipitated on the balls 31. These films are only slightly adherent to the polished surfaces of the balls 31 and the constant rolling action causes them to be removed as small flakes. These flakes are thinned by further passages between balls and are mostly suspended in the electrolyte by the continual motion. After a period of rotation the barrel 5 is removed and the flakes extracted, washed and dried, ready for moulding under a pressure of approximately 40,000 lbs. per square inch, without sintering, into contact tips &c. Similarly, flaked powders of copper, nickel, iron and other metals may be produced. U.S.A. Specifications 2,288,122 and 2,307,668 are referred to.

Abstract: 801,624. Platen printing machines. SAROGLIA, E. May 13, 1955 [May 14, 1954], No. 13935/55. Class 100(2) In a high speed platen printing machine the sheet-feeding arm 18 is operated by the oscillating motion of the platen 1. The platen is mounted on a frame 6, and is swung about its axis by means of a crank 2, connecting rod 3, and toggle levers 4, 5 pivoted, respectively, to the frame at 45 and to the platen at 46. The platen 1 rocks a shaft 9 (not shown) through a link 7 and a lever 8 secured to the shaft, and a second lever 10 (not shown) secured to the shaft has a block thereon engageable in an open-ended slot 12a in a triangular slotted arm 12 pivoted at 49 in a separate frame 13. The frame 13 carries the sheetfeeding and delivery mechanism, and is mounted on wheels so that it can readily be moved away from the platen &c. frame 6, the block and open slot 12a means facilitating ready connection and disconnection of the frames. Thus the motion of the platen 1 rocks the arm 12 about its pivot 49. A link 14 is pivoted at one end in the slot in the arm 12, and at the other end to a two-armed lever 22, pivoted at 63, and a two-armed lever 15, pivoted at 62. The upper end of lever 15 is pivoted at 54 to the' sheet-feeding arm 18. The lower end of the lever 22 is connected by a link 21 to a bell-crank lever 20, freely mounted on a driven cross-shaft 29 to which is pivoted an arcuate lever 16 having a roller engaging a cam 19 secured to the shaft 29. The lever 16 and roller are urged towards the cam 19 by a spring 23, pivoted lever 25, and spring 24. A rod 28 is pivoted to the lever 16 and to the sheet-feeding arm 18, so that the cam 19 modifies the path of movement of the arm 18: this arm movement can also be modified by adjusting the ends of the link 14 in the slot 51 in the arm 12 and a slot in the lever 22. The arrangement is such that a rest period of the sheetfeeding arm 18 on the sheet pile, equal to a quarter of the time of an operating cycle of the machine, is achieved by a combination of three dead centres. In this position, the crank 2 and connecting rod 3 are in alignment, the levers 4, 5 are horizontal, and the link 7 is in alignment with the axis of the platen 1. The movable frame 13 can be clamped in its operating position by a pair of forks on the frame 6 engaging a pair of rotatable blocks on the frame 13. The blocks are secured on a cross-shaft which can be rocked by a lever to release the frame 13. The shaft 29 has secured thereon a toothed wheel engaged by a pinion which is driven by a sprocket chain from a motor-driven shaft on the frame 6. Specification 581,554 is referred to.
