Title: Improvements in and relating to stranding cabling, rope-making and like wire-workingmachines
IPC: D07B7/08
Filed: 1946-11-14
Abstract: 618,834. Stranding, cabling, and rope-making machines. LARMUTH, L. J., and LARMUTH, A. Nov. 14, 1946, No. 33791. [Class 109] An electric stopping device for a stranding, rope making and like wire-winding machine comprises an electricity conducting member through which the wire passes without touching it when 'under tension in the machine, the conducting member being in an electric circuit insulated from the machine and electrically connected to a trip or stopping mechanism and being closed or short circuited when touched by a broken, slack or loose piece of wire. The stopping devices are mounted on the machine at any number of suitable positions, and in the form shown a single device mounted on the machine 6 comprises a plate 7 secured to the machine and mounting an inclined bracket 9 and a block 10 having a guide member for the wire consisting of a flared sleeve 11. The bracket 9 carries a tube 12 in which, insulated therefrom, is a second tube 13 of good electricity conducting metal, such as copper, carrying a terminal 14. In normal working of the machine, the wire passing through the tube 13 and the guide sleeve 11 is kept taut and away from contact with the tube 13, but on breakage, running slack or failing by emptying of the bobbin falls and contacts with the tube 13. An electric circuit is then completed of which the tube 13 and mechanism such as a relay to operate a trip gear for knocking off the machine, are a part, the frame of the machine constituting an earth for the current. The block 10 and flared sleeve 11 may be replaced by a guide pulley. In a further modification, the tube 13 may be arranged in a horizontal mounting between a pair of guide blocks having apertures lined with tungsten carbide &c. to limit the wear thereof. The tubular conducting member may be replaced by an apertured plate or pair of plates through which the wire passes.

Abstract: 301,083. Lemaire, J. H. Nov. 25, 1927, [Convention date]. Rolling. - Apparatus for forming plate or sheet glass consists of a trough 11 rectangular in plan and provided with a slot 12 the width of which can be regulated by movable plates 13. Molten glass, placed in the trough, flows out through the slot 12 in the form of a sheet the thickness oj which is regulated by the plates 13. The sheet thus formed passes between rollers 5 which reduce it to the final thickness. The trough may be charged with glass either from a pot or ladle or direct from a tank furnace. The trough and rollers may be fixed above a movable table, or a roller conveyer, for receiving the finished sheet, or they may be arranged to move horizontally above a stationary table. In a modified construction, the plates 13 are replaced by rollers which form the sheet, and wire netting may be pressed into the glass by these rollers when making reinforced glass.

Filed: 1976-08-18
Abstract: 1519236 Testing ampoules LEZARD SA 18 Aug 1976 [12 Feb 1976] 34443/76 Heading C1M A device for identifying and rejecting defective ampoules, to ensure that they are open for filling, comprises a plurality of sensors mounted on a reciprocable slide and jaw means actuated by said sensors, when an ampoule is not open, for extracting such defective ampoules. The sensors, which are mounted on plate 8, each comprise a pin 9 which slides in sleeve 5, a head 15 being provided at one end of pin 9 and, at the upper end of pin 9, a larger diameter zone 9', a narrower zone 9" and a sensor ferrule 9<SP>111</SP>. In use, downward movement of the reciprocable slide (16-Fig. 1, not shown) brings head 15 into contact (c) with table 18 (Fig. 1), so that the pin 9 slides upwards. Zone 9' then forces balls 7 outwards, the balls 7 in turn forcing arms 11 outwards against the action of spring 12. On subsequent upward movement of the slide and sensor, the ferrule 9<SP>111</SP> may enter the open neck of an (inverted) ampoule without effect. If, however, the neck is not open, the ferrule 9<SP>111</SP> and pin 9 are pushed down by contact with the ampoule, so that narrow zone 9" engages balls 7 and allows arms 11  to spring together and hold the neck of the ampoule. The device then moves down again, and contact with table 18 forces bolt 4 upwards against springs 32 so that the defective ampoule is released from arms 11 by transverse plate 1. The arms 11 are simultaneously opened again by the action of pin 9.

In an arrangement in which a gating circuit, Fig. 2, is fed over inputs A, Band T with distorted pulses UA, UB and timing pulses UT, Fig. 1, to produce pulses of the length of a timing pulse, the output of the gate is applied to an amplifier, such as the transistor amplifier Tr1, Tr2 to produce output pulses which are lengthened by at least the rise time of the input pulses. The timing pulse UT occurs after the elapse of the rise time ta of the input pulses UA, Us so that a pulse of the duration of pulse UT is fed from the diode gate Rl over isolating diode R2 to the input transformer of the transistor amplifier, the input being sufficient to drive the second transistor Tr2 well into saturation so that conduction continues after the cessation of the input to the transistor and decays according to the curve Uc, the input pulse being lengthened by a period t0. The output pulse Uc may be used in a further gating circuit with similar input pulses, the timing pulse then being delayed with respect to the pulse UT employed in this circuit. In a modification, Fig. 3 (not shown), an inhibiting circuit is formed by feeding the input pulse applied to terminal B to the base of the transistor Tr1.

Title: Method and apparatus for depositing metal film under vacuum

Filed: 1961-09-27
Abstract: 927,587. Coating by vapour deposition. SPERRY RAND CORPORATION. Sept. 27, 1961 [Jan. 3, 1961], No. 34718/61. Class 82. In a vapour deposition process of coating a substrate such as glass with a thin film of a metal such as platinum, lead, zinc or a magnetic nickel-iron alloy such as Permalloy or Perminvar, a sufficiently high voltage, e.g. 20 kv., is applied to the ends of a wire of the metal under vacuum conditions to explosively evaporate the metal. The voltage is such that the evaporation is complete in one micro second. As shown in the drawing the metal wire 14 is clamped by voltage balls 16 and 18 in a vacuum chamber 10, the high voltage being applied to the ends of the wire from terminals 22 and 24. The wire is connected via 18 to a conductor 28 which normally hangs freely between a fixed block 30 and a spring block 32. In order to hold the wire taut during the evaporation the conductor 28 may either be permanently fixed to block 30 or alternatively at the start of the deposition a current from 46 passes via 42 and fuses wire 40 which then allows the spring 36 to bias block 32 to block 30 and thus clamp the conductor 28. The chamber 10 is evacuated to between 10<SP>-4</SP> and 10<SP>-6</SP> mms. Hg and the wire is preheated electrically to about 1000 C. by closing switch 48, current being supplied from battery 50 via leads 54 and 56 and connector 56 which is disconnectably held in contact with supply conductor 20 by a spring 64, a fuse wire, and rigid conductor 70. On completion of the preheating the switch 48 is opened or preferably switch 72 is closed and current from battery 74 fuses the wire 66 which results in the connector 58 being disconnected from conductor 20 due to the bias of spring 78. The preheated and outgassed wire may be cooled prior to applying the high voltage current from condenser 86 or the voltage for explosive evaporation may be applied to the hot wire and a coating is formed on a masked substrate 92. The cold ends of the wire 14 may also be masked to prevent the formation of a perforated deposit. For materials with a high vapour pressure such as lead and zinc they may be encapsulated in polyethylene prior to being submitted to the explosive evaporation. U.S.A. Specification 2,900,282 is referred to.
