Perforated tickets are printed by apparatus adapted to produce periodic or aperiodic patterns of lines on the tickets overlapping the perforations such that the pattern is displaced successively from ticket to ticket in the feed direction. Two cylinders, Fig. 4 (not shown), print on the ticket web, each cylinder including a plate 20 carrying a wavy or zig-zag pattern which is printed out of phase with the other pattern. The pattern is displaced from ticket to ticket by stepping a pattern-printing cylinder carrying a plate (23), Fig. 7 (not shown) by means of a ratchet mechanism (28), which engages teeth on a ring-shaped support (24). Each cylinder may print in a different colour and may carry a numbering unit 13, 14 so as to print a number on both sides of the perforations, the numbers on each ticket being at right angles to each other and in differently coloured inks. The perforations may be formed before, during, or after printing.

Title: A microminiature electric incandescent lamp
IPC: H01K3/02
Filed: 1962-06-01
Abstract: 983,465. Electric incandescent lamps. PATENT-TREUHAND - GES. FUR ELEKTRISCHE GLUHLAMPEN. June 1, 1962 [June 2, 1961], No. 21198/62. Heading H1F. A very small incandescent lamp, e.g. having a tubular envelope of about 0.6 mm. diameter and a filament the diameter of which is less than 10 microns, has a single wire of high melting point metal, e.g. tungsten, constituting both the filament and the leading-in wires, the portion serving as the filament having a smaller cross-sectional area than that forming the leading-in wires. The difference may be produced by etching away part of a uniform wire of the cross-section required for the leading-in wires to produce a filament wire of smaller cross-section or by starting with a wire of cross-section appropriate to the filament and producing thickened portions for the lead-in wires by electrodeposition. The deposited metal may be tungsten or another metal such as gold or copper. The lead-in portions 3 may be fixed into a glass bead 7 and inserted in a tube 4 closed at one end. After evacuation, the tube is sealed to the bead. To ensure accuracy in the finished length of the lamp, the glass tube may be relatively long and is sealed at the open end after evacuation. The tube can then be sealed off at the required part, the end with the initial closure being removed. Specification 659,992 is referred to.

Abstract: 984,662. Spinning. CALUMET & HECLA Inc. June 5, 1962 [June 20, 1961], No. 21689/62. Heading B3J. Metal spinning apparatus comprises a tool rest, a fulcrum lever pivotally mounted on the tool rest, a spinning lever pivotally mounted on the fulcrum lever and carrying a spinning tool thereon, and a hydraulic jack acting between the tool rest and at least one of the levers, the jack being responsive to forces manually applied to the lever to provide power assistance to the manual operation thereof. The apparatus comprises a lathe 10 having an electrically driven head 12 on which is secured a volumetric chuck 16 against which a metal blank 18 is held by a tail block 20, and a tool rest arrangement 22. The tool rest is positioned spaced laterally from and parallel to the common axis of the head, chuck and tail block and comprises a member 24 having extensions 26, 28, a shaped fulcrum lever 30 pivotally mounted on the member 24 by a pin 32 and a spinning lever 34, pivotally mounted on the offset portion of the lever 30 on the end of which is mounted a suitable tool 38, e.g. a wheel. Double acting hydraulic jacks 40, 42 are pivotally mounted between the extension 28 and lever 34 and extension 26 and lever 30 respectively. Fluid is supplied to the jacks from a pump 68 and reservoir 70 and their operation is regulated by control valves 72, 74 respectively, actuated by handles 76, 78 pivotally mounted on the levers 34, 30 and connected to the operating members of the valves by ball studs 82, 86 respectively. The control valve comprises a body 90 threaded at 92 to receive one end of an L-shaped arm 94 the other end of which is rigidly fixed to an extension 96 of the lever 34. A bore 98 of the body houses a reciprocating valve 100 and defines passageways 102, 104 and passageways 106, 108 communicating with the jack 44 on opposite sides of a piston 50. A radial cavity 114 opens into the bore 98 between the passageways 106, 108 opposite which is a passageway 116 connected to the reservoir 70. The valve 100 comprises a central shaft 120 having three annular lands 122, 124, and 126 and is centred in the body by a compression spring 128 and washers 130, 132. The ball studs 82, 86 are connected to the shafts 120 so that forces applied manually to the handles 76, 78 to effect movement of the levers 30, 34 adjust the position of the valves 100 to allow fluid under pressure to flow to the appropriate side of the pistons 50 and provide power assistance to the levers and displaced fluid to return via the cavity 114 to the reservoir 70. Manual forces of less than 4 1bs. do not overcome the compression spring 128 and hence the valve 100 remains in its neutral position thus allowing fluid to be displaced freely from one side of the piston to the other, so that the spinning lever 34 is actuated without power assistance.
