Title: Electric arc cutting machine
IPC: B23K9/013
Filed: 1935-07-03
Abstract: 459,292. Dividing by fusion. STROBEL, K., 601, North Greenleaf Avenue, Whittier, California, U.S.A. July 3, 1935, No. 19054. [Class 83 (iv)] [See also Groups XI, XXIII, and XXXV] In an electric-arc cutting machine of the kind in which an electrode provided with an elongated edge such as a disc or endless band has imparted to it a unidirectional movement with respect to the work, the arc is controlled magnetically by a coil so located that elongation of the arc at the sides of the electrode is avoided and the arc confined between the edge of the electrode and the work. The arc is sufficiently wide to ensure removal of the metal, the sides of the cut being clear of the sides of the electrode. Cutting is also effected without heating the metal on either side of the cut. The work 6 is secured in a vice 4 over a slot 5 in a table 2 connected to one terminal of the supply, the other terminal of which may be connected to a toothed disc 7 rotated at a high speed, e.g. 5000 r.p.m. for an 18" disc, either direct or through gearing by a motor 9 bolted to a slide 28, which may be traversed on a guide 34 by a screw 39. The guide is vertically adjusted at one end by a screw 42, the other end being similarly adjusted or being connected to a slide 45 attached to a counterweighted chain or cable 47. Secured to the motor frame is a non-magnetic guard 18 for the disc, which carries an adjustable spring-pressed contact brush 25 engaging a conducting ring 17 pressed against the side of the disc 7. The disc is mounted on its shaft 8 through insulating rings 12, 15 and bushing 13. The disc has a saw edge and the arc is struck either by contact of the teeth with the work or by bridging the gap by a wire brush, or by laying a strip of carbon &c. in advance of the work so as to start the arc initially between the carbon and the disc. The arc is struck between the work and the points of the teeth which assist in drawing the fused parts of the work in the direction of movement of the disc. The ends of the teeth are swaged out to provide the greatest width of the disc so that the arc is of sufficient width to effect the cut while keeping the sides of the disc clear thereof. The arc is confined between the edge of the disc and the work by a magnetic field created by a coil 54 wound in the form of a tapered helix, the taper of which is directed towards the edge of the disc. This coil may be connected in series with the disc, the current passing from terminal 61 through switch 62, current limiting resistance 63, coil 54 and then by strap 60 to the brush 25. The slide 28 may be traversed by hand, but in order to keep the length of the arc constant it may be traversed by a motor 70, the armature of which is connected across the arc and the field 72 connected to a constant source of energy.

Title: Improvements in or relating to keying devices for cryptographic apparatus
IPC: G09C1/08
Filed: 1959-06-08
Abstract: 927,514. Ciphering. ANSTALT EUROPAISHE HANDELGESELLSCHAFT. June 8, 1959 [June 7, 1958], No. 19554/59. Class 146 (2). The cryptographic device keying mechanism described in Specification 742,181 is modified to ensure that while the keying members are irregularly advanced no combination will recur until all possible other combinations have occurred once. Thus the slide bar drum 14 is provided with a lug 6 which ensures that the first key wheel 9 is advanced one step every revolution and the actuating slide bars 1-3 are provided with lugs 5, to engage the intermediate wheels 7, so positioned in relation to lugs 4, which displace the slide bars to their operative position, that the bars are only placed in an operative position by a control member 8 associated with a preceding keying member and not by a control member associated with a following keying member. Thus if in a revolution of the drum 14 a pin 13 on the wheel 9 is in an operative position all the bars 1-3 will be moved to their operative position to operate each keying wheel 10-12 while if a pin 13 is not operative on the wheel 9 but is on the wheel 10 only the bars 1, 2 will be moved. In modifications instead of the key wheels being used to control a ciphering teletypewriter as described in Specification 742,181 a mechanism can be controlled in response to the position of the slide bars or alternatively the key wheels may be constructed as electric commutators. Further modifications may include the provision of fixed bars on the drum 14 which give additional steps to the intermediate wheels 7 during each drum revolution while the whole device may be electro-mechanical or purely electrical instead of mechanical. Specification 455,333 also is referred to.

Abstract: 688,933. Delivering booklets in counted batches. SADLER, C. J. Aug. 8, 1950 [Aug. 19, 1949], No. 19680/50. Class 100(i) Stitched booklets 9 are delivered in counted batches from a trimming machine on to a conveyer 13, one booklet' in each batch being displaced laterally of the batch by a displacement arm 73 displaced after the required number of booklets forming a complete batch has passed beneath a feeler 60. The feeler 60 carried by a jointed rod 57, 58 is maintained in a raised position by the presence of a booklet, but if no booklet is present beneath the feeler 60 due, for example, to a booklet being ejected as imperfect by the trimming machine then the feeler 60 drops, thus lowering a control lever 53 in a counterclockwise direction about a shaft 54 and thus preventing a pawl 33 from engaging a ratchet wheel-19 having the same number of teeth as there are booklets in a batch. The pawl 33 is pivotally mounted between lugs 32 secured to a shaft 17 rocked by a lever 27 driven by an arm 15 reciprocated by the trimming machine. The shaft 17 carries a quadrant 30 meshing with a pinion 31 on a cam shaft 18 carrying a main cam 39 which periodically lifts the lever 53 and a secondary cam 41 which can hold the lever 53 in raised position by means of an extension 55 to permit the passage of a booklet 9, if present, beneath the feeler 60 which then descends upon the booklet. At each oscillation of the lever 27 the pawl 33, if not prevented from engaging the wheel 19, rotates the wheel 19 one tooth, such that at each revolution of the wheel a projection 23 on a cam member 24 secured to the ratchet wheel shaft 16 rocks a lever 64 which in turn rocks a shaft 71 carrying the arm 73. If however, no booklet passes beneath the feeler 60 during the upward stroke of the member 15 then the feeler 60 drops, thus causing the pawl 33 to be raised clear of the wheel 19 by the lever 53; consequently the cam member 24 is not rotated.
