Title: Improvements in package binding machines
Inventor: COOK PETER ROY
IPC: B65B13/02
Filed: 1961-09-02
Abstract: 1,013,685. Package winding machines. PACKAGE SEALING CO. (EXPORT) Ltd. Nov. 8, 1962 [Sept. 2, 1961], No. 31637/61. Heading B8C. [Also in Division F2] A machine for binding packages comprising means for feeding the binding material endwise, a guide to receive it and form it into a loop, means for tightening the loop round the package, and a connecting device for the binding material ends, in which the loop forming operation is controlled or powered by pneumatic means has a controlling air-circuit including a bleedport arranged so that the free end of the binding material effects a change in conditions at the bleed-port and terminates at least the feeding operation. The binding material, e.g. flat wire, is fed from a reel 17 by a reversible feed 14 which comprises two driving rollers 66, 67 above which are two pressure rollers 70, 71 mounted in a holder 72. The holder has a neutral position and can be tilted anticlockwise by cylinder H or clockwise by cylinder G and the feed means is mounted on a member 68 pivoted at its upper end at 69. Initially the wire is fed forward by rollers 66, 70 when the holder is tilted anticlockwise and passes through a twister pinion gear-box 13, which is as described in co-pending Specification 1,013,684 (see Division B3), around a channel section guide ring 11 movably mounted on a plate 10, the latter closing the channel, and back into the box 13. The end of the wire then obturates a bleedport provided in a groove 62 which bleed port is connected in a pneumatic control circuit (Fig. 4, not shown). This causes air cylinders A to move the guide ring away from the plate 10 to release the wire and also causes the holder 72 to tilt clockwise to reverse the feed of the binding material and tighten the loop around the package. This continues until the tension in the wire is equal to the pull of the rollers 67, 71 when the rollers ride up the wire and cause the plate 68 to move against the bias of a spring 74. This trips valve V, causing a pneumatic motor C to actuate an extra tension device consisting of a lever 76 having two parts pivoted at 79 the top part of which carries jaws 80, 81. These jaws come together and give the binding material an extra pull. The overlapping ends of the binding material are then joined by the twister pinion 20a. The feeding sequence may be initiated by the package being placed within the loop and the reel 17 is controlled by a cylinder K which is actuated from a slack take-up device 18. During the feeding forward when all the slack has been taken up, a lever 87 acting against a spring 90 and a plate 91 closes a bleed-port 108 which in turn causes the cylinder K to release a brake lever 94 and rotate the reel 96 by ratchet means so that binding material is fed forward. Specification 1,013,684 is referred to.

Title: Improved manufacture of oxide cathode discharge tubes
IPC: H01J9/04
Filed: 1925-12-23
Abstract: 245,146. Naamlooze Vennootschap Philips' Gloeilampenfabrieken. Dec. 24, 1924, [Convention date]. Drawings to Specification. Vacuum tubes; R÷ntgen-ray tubes.-A process of making an oxide-cathode discharge tube consists in mounting in a discharge tube a metal core having its surface partly or wholly oxidized, and one or more electrodes carrying one or more compounds, such as the azide, of one or more alkaline earth metals, heating the electrodes by currents induced by a high-frequency magnetic field to decompose the azide and precipitate on the core the alkaline earth metal, which is subsequently oxidized. The core may consist of a wire or other body of nickel or a noble metal, or of platinum-rhodium with or without a coating of copper. Barium azide, dissolved in water, is trickled on the inside of one or more anodes, and the water evaporated before mounting the anode in the tube. After the preliminary evacuation the anode is brought to incandescence by induced currents so as to decompose the azide, and deposit barium on the core. Oxidation of the layer of barium may be effected by the oxidized surface of the core, or by admitting oxygen to the tube. Gas is removed from the grid by electron bombardment from the anode, the grid being maintained at a positive potential and the tube connected with the exhaust pump. During this operation the cathode may be protected from bombardment by maintaining it at the same potential as the anode, and by heating slightly. Any barium deposited on the tube serves to improve the vacuum or to remove impurities from the gas filling. Specification 214,262 is referred to.
