Title: Improvements in or relating to vending machine for thread spools and other substantially spool-like articles
IPC: G07F11/02
Filed: 1965-06-14
Abstract: 1,061,849. Coin-freed vending machines. METTLER-MULLER A.G. June 14, 1965 [June 16, 1964], No. 24983/65. Heading G4V. A coin-freed vending machine for dispensing from a selected one of a number of storage channels 1 a thread spool 2 includes a selection plate 18 actuation of which moves a coin-slot blocking plate 31 to inoperative position by electrically-controlled means after a predetermined time-delay to allow the customer to change his mind, the plate 31 returning to blocking position after a further time-delay. The spools are released in succession by axially. spaced, angularly-offset supports 5, 6 (Figs. 1, 2, not shown) alternately engaging beneath the two bottom-most spools. The plate 18 is coaxially fixed for rotation with cam disc 21 and switches WS1-3. In use the plate 18 is turned to select a thread colour and coin slot 38 is opened after a time-delay. If no money or incorrect coins or tokens (checked by a tester 27) are inserted then switch S2 is not actuated causing after a delay re-closure of slot 28 and pivoting of flap 29 to return larger coins or tokens caught thereby. Over-smal coins should fall directly into return receptacle 42 through a through-passage in the tester, but the through-passage is also opened simultaneously with pivoting of flap 29 to free jammed coins. On insertion of correct money switch S2 is closed, causing a pin 24 to project through an associated hole 23 of disc 21 to correct any non-exact setting and to block further rotation. A magnet M6 associated with the selected channel 1 is energized via switch WS1 to release a spool 2, and certain magnets M7 are energized via switch WS2 and block and peg mechanism 44 to give change from. tubes 45 opening into receptacle 42. The slot 28 is then closed and flaps 29 and 43 actuated to allow inserted coins to fall into cash container 40. Magnet M4 is energized to return plate 18 to its starting position, the remainder of the apparatus also being returned to its original position. The number of spools in any one channel 1 is indicated by a counter 11 which closes a switch S3 to light a lamp 17 or give audible warning should the channel be emptied. Switch WS3 co-operates with counters 11 to return coins if the selected channel is empty.

Abstract: 669,640. Discharge apparatus; cathode materials. BENDIX AVIATION CORPORATION. Sept. 24, 1948 [Nov. 10, 1947], No. 24998/48. Class 39 (i). A " cold cathode " gaseous discharge tube, by which is meant a tube having two or more electrodes immersed in a gas at a relatively low pressure, the discharge being started by the application of a sufficient voltage between the electrodes without initial heating of the electrodes, is characterized by a cathode containing a mixture of a compound of an element of low work function, a substance to displace the element of low work function from said compound during discharge, and free nickel particles to provide points at which the arc of discharge occurs. The tube comprises a glass sleeve 11 having fixed therein and made integral with the bottom edge thereof a second glass sleeve 12 terminating in a three-armed glass press 13 on which is fixed a ceramic insulator 14 having openings 15, 16 and 17 of different diameters, and provided with three radial slots 19, the upper portion 21 of the insulator being supported by three wedge-shaped pillars 20. Pins 24 inserted in three pairs of openings 22-23 in the insulator 14 and in the press 13 respectively, serve to align these components. The cathode comprises a pill 30, made by compressing caesium chloride, aluminium powder, and nickel filings, held in a cup 26, preferably made of nickel, by a wire mesh screen 31; preferably also made of nickel. The cup 26 is mounted in an annular groove 25 in the insulator 14 and is made integral with a cap 27, preferably made of the material known under the Registered Trade Mark " Kovar," which is hermetically sealed to the glass sleeve 11 and forms part of the envelope of the tube, thus providing efficient cooling for the cathode. A cylindrical graphite grid 32, fixed within the openings 15 and 16 of the insulator 14, has a tapered bore forming a partial enclosure for a rod-like tungsten anode 35, and is spaced therefrom by a glass bead 36. A lead-in wire 38 is connected to the grid 32 by a contactor 40 fixed into the glass press 12 and fitting in an opening 41 in the insulator 14. With proper voltage applied to the grid 32, a glow discharge takes place between the grid and the cathode 30. The decomposition of the caesium chloride of the cathode forms a cathode spot on the pill which emits electrons to form a low-resistance path from the cathode to the anode 35. An arc discharge then takes place between the anode and the cathode. The tube filling comprises an inert gas, preferably helium.

Title: Manufacture of regenerated cellulose sausage casings
IPC: B29C48/10
Filed: 1953-09-14
Abstract: <PICT:0742031/IV(a)/1> <PICT:0742031/IV(a)/2> Tubular regenerated cellulose sausage casings in spirally coiled shape are obtained by extruding viscose through an annular nozzle into a spinning bath which exerts a coagulating action only on the film, inflating the coagulated tubular film by air or other inert gas, winding the inflated film in one or more spiral turns around a cylinder, transforming the coagulated viscose into regenerated cellulose while the film is so wound and finally subjecting the film to the usual washing, after-treatment and drying processes. The cylinder may rotate and the wound tubular film may be caused to move axially along its surface.  Regeneration may be effected by treatment with a regenerating liquid and/or by infra-red heating.  As shown (Fig. 1), viscose is extruded through an annular nozzle 1 into an aqueous coagulating bath 2 containing, for example, sulphuric acid and ammonium sulphate.  The coagulated tube 3 is inflated between nip rollers 4 and 9 and, in its inflated condition, is wound around a rotating cylinder 5 (see also Fig. 2).  The surface of cylinder 5 comprises a plurality of endless ropes (not shown) which move axially of the cylinder and serve to traverse the coiled tube along the cylinder. Regeneration is effected by a liquid 7 comprising, for example, aqueous sulphuric acid and/or by infra-red radiation from a source 8.  In a modification, lengths of inflated tube are coiled around heated and non-rotary cylinders which are then transported by an endless chain through a heating channel, a cooling zone and regenerating and after-treatment liquids.  Heating on the cylinder and/or in the channel may, however, be omitted.

Title: Means for following the edge of sheet material, particularly for measuring or control purposes
IPC: G01B5/06
Filed: 1931-09-11
Abstract: 387,031. Coating webs; folding edges; cutting sheet material. DUNLOP RUBBER CO., Ltd., 32, Osnaburgh Street, London, and WILSON, H., Fort Dunlop, Birmingham. Sept. 11, 1931, No. 25501. [Classes 31 (i), 42 (i), and 140.] An apparatus particularly for use in treating or otherwise handling sheet material is provided with a roller or rollers arranged obliquely to the edge of the sheet so as to cause the roller or rollers to follow the edge. The transverse or relative movement of the roller or rollers against an applied pressure is utilized to effect the operation of measuring or control mechanism. The invention is shown applied to a calendering machine in the operation of which a sheet of material is coated with rubber, the edge rollers being connected to means for measuring the area treated. The fabric a, as shown in the Figure, is passed over a rotating calender roll b and is engaged at the edges with rollers 1, 2, rotatably mounted on axes inclined to the edge of the sheet at the end of links 3, 4 pivotally connected to a pair of arms 7, 8, mounted in a fixed bracket 9. The arms 7, 8 are slotted to admit of adjustment of the pivots of the links 3, 4 for different widths of sheet. A link 14 pivoted on the axis of the arms 7, 8 is connected by a fixed chain 15 to the link 3 and a chain 16 attached to the link 4 passes over pulleys 17, 18 on the link 14 and is fixed at its other end to a quadrant 19. The quadrant 19 by means of other chains 22, 25 and quadrant 21, 23 is connected to a weight 26 which tends to move the edge rollers 1, 2 toward each other. Attached to the quadrant 23 is a lever 27 connected to a cone pulley 29 displaceable in accordance with the movements of the quadrant along a keyway on the shaft of the calender roll b. A friction wheel 32 contacts with the cone pulley 29 and through a flexible connection 34 drives an area meter 33. Instead of a meter an indicating or recording member may be actuated by the connection 34 so as to show the variations in the width of the fabric. In an alternative form of apparatus the sheet of material may be held stationary and the rollers caused to move from end to end of its length. The movement of the chain 16 due to the transverse movement of the rollers may be utilized to regulate the output of the apparatus or effect the control of means for trimming the selvedge, marking a border on the sheet, folding over marginal edges, centralizing the sheet, and for adjusting a continuously weighing apparatus. -
