Title: Improvements in or relating to blowpipe machines for cutting metal
IPC: B23K7/00
Filed: 1924-09-08
Abstract: 243,816. Hancock, L. J., and Hancock & Co. (Engineers), Ltd. Sept. 8, 1924. Perforating and dividing by fusion.-In a blow-pipe machine for cutting metal of the type in which a tracer follows the lines of a drawing as described in Specification 226,846, the tracer is replaced by rollers bearing on opposite sides of a flexible guiding strip supported from the usual table or board on which the drawing is normally placed or from a member located thereon. The strip 2 is secured in slots in holders 3 which have shanks engaging holes in the table or a board placed thereon, or pins fitting in the board in the manner of a drawing pin, or which may engage undercut slots in the table. Clamping screws may be provided at each side of each holder so as to provide a transverse adjustment. In order to direct the tracer rollers towards or away from the cut, a detachable piece such as 6 may be removed from the holder 7 after the first passage of the rollers and replaced in another position for the second, passage. The part 6 may form part of or co-operate with a length of guiding strip 9. The tracer rollers 10, 11 engage opposite sides of the strip and are geared together at 13, 14, so as to avoid slipping round curves and thus to enable smaller rollers to be used. The roller 10 is driven bv a motor 12 and the roller 11 and gear 14 are hollow and mounted on a fixed spindle 15 carried by a spring-pressed pivoted member 16. In order that the edge of the cut may correspond with the centre line of the strip, the axis of the blow-pipe coincides with that of one of the rollers and the width of cut is made equal to the diameter of the roller plus the thickness of the strip. When cutting thick metals, the width of cut is greater and the guide strip may be offset. The strip may be placed on the board and bent to the form of the drawing. Specification 130,450 also is referred to.

Title: Improvements in or relating to sound recording and reproduction
IPC: H04R1/16
Filed: 1956-07-10
Abstract: 814,015. Gramophone pick-ups. SUGDEN, A. R. July 3, 1957 [July 10, 1956], No. 21293/56. Class 40 (2). [Also in Group XXXIX] Apparatus for cutting or reproducing hill - and - dale and lateral sound channels, combined in a single groove on a disc or cylinder record, e.g. a stereophonic record, has a stylus connected to two separate transducers (respectively for vertical and lateral stylus movements) by connections each adapted to transmit the appropriate movements but to isolate its transducer from any movements appropriate to the other transducer, at least one of the connections consisting of a rod so mechanically coupled to a link member that the rod may rock about the coupling but endwise rod movement is transmitted by the coupling. Fig. 2 shows the undersurface of a cutter head having a sapphire &c. cutter 28 located in a sole-plate, the two parts 16, 17 of which, clamped to the respective limbs of a horseshoe magnet and aligned by a spacer 18, define slots 14, 15 at right angles to one another; the cutter is coupled to moving coil generators 22, 25 located in the slots and rotatable in brackets 23, 24 and 26, 27 fixed to an L-shaped member 30 pivoted at 20, 21 to the sole-plate. The cutter couplings, Fig. 3, consist of cantilevers 31, 35 of rectangular crosssection so as to flex in one direction but not in the other, part 31 being rigid to transmit lateral movement, and part 35 vertical movement; a short vertical stylus 29 carrying the cutter 28 is fixed to part 31 plugged at 32 into the lateral generator 22, and a point 36 on part 35 of the vertical generator 25 engages a hole 37 at the top of the stylus 29 which is supported by a rubber &c. pad 34 fixed to the bracket 24. A pick-up head, Fig. 5, has two moving coil generators 54, 55 rotatable respectively about vertical and horizontal axes in housings 51, 52 fixed by a carrier 53 to a pick-up arm 50; the stylus 57 is welded or fixed by adhesive to a cantilever 56 fixed to the generator 54 and inclined, Fig. 5, or stepped, Fig. 7, to bring the stylus point 58 clear of the bottoms of the housings 51, 52; the pointed top of the stylus engages a recess in a lever 60 fixed to the generator 55 and may pivot therein to absorb lateral movements; the rectangular crosssection of the lever 56 gives the required lateral rigidity and vertical flexibility, which latter, in the Fig. 7 form, is increased by a notch 62. Moving iron or crystal transducers may replace the moving coil generators 22, 25 or 54, 55. According to the Provisional Specification, the magnet of the cutter head may itself replace part 16, its limb ends being at right-angles to one another; the part corresponding to part 17 then constitutes a triangular keeper. The upper part of the stylus 57 of the pick-up head may be replaced by a rod having both ends pointed and engaging hemi-spherical cups in parts 56, 60.

Filed: 1926-09-01
Abstract: 269,391. Siemens & General Electric Railway Co., Ltd., Downes, F., and Rogers, W. D. Sept. 1, 1926. Retractive switches; hand levers, interlocking. -A control lever 19 for use in railway signalling apparatus is pivoted at 20 on a quadrant 18 and has a second arm connected at 22 to a rod 21 connected to the controlled mechanism. The lever 19 has a catch-handle 23 connected by a rod 25 to a spring-pressed plunger 24 moving over a segmental guide 1 carried on insulating blocks 2. The guide 1 carries on its underside two electric switches or contact-makers in series, each switch comprising a resilient strip 8 having one end anchored in an insulating block 4 and carrying a movable contact adapted to engage a fixed contact on insulated plate 10. The outer ends of the strips 8 are connected by insulating blocks 9 to resilient strips 5 anchored at one end and carrying insulating blocks 6 at their other ends which project through apertures in the guide 1. Thus when the control lever is in either of its extreme positions and the catch-handle is released, the plunger 24 engages the projection 6 of one of the contact makers so opening the circuit of a locking solenoid 30. The core 29 of this solenoid on release falls into a notch 28 in a locking bar 27 pivoted at 26 to the control lever which is only released when the lever is again grasped. Specifications 1453/81 and 23929/09 are referred to.

Filed: 1952-08-27
Abstract: 736,999. Pulse-amplifying circuits. STANDARD TELEPHONES & CABLES, Ltd. Aug. 27, 1952, No. 21545/52. Class 40 (6). Pulses to be amplified are applied to the trigger electrode of a gas-discharge tube which fires only in the presence of a pulse from a first source applied to the anode, the tube subsequently being extinguished by a pulse applied from a second source. The Figure shows a pulse repeater in which input pulses are applied at T to the trigger electrode of cold-cathode gas tube PT the bias of which is adjusted by switch SW so that the tube fires only when a positive pulse applied to the anode from terminal A coincides with an input pulse. When the tube fires the cathode which is normally held at - 50 volts by " catcher " diode MR1 rises in potential so that resistor R1 becomes the cathode load as described in Specification 772,643 and an output pulse is produced. The anode pulse is immediately followed by a positive pulse which is applied to the cathode circuit at terminal C so that the tube is extinguished. Rectifier MR3 acts as a D.C. restorer and rectifiers MR2, MR4 isolate the anode and cathode circuits from their respective pulse sources.

[Class 120 (iii).] Staple fibres are produced by cutting thoroughly wetted bundles of continuous filaments into staple lengths. The filaments are preferably cut in thick bundles produced by cutting a hank formed by winding the filaments on to a smooth cylindrical drum by a parallel wind, continuously with their production or otherwise. The filaments are preferably wetted whilst on the drum by immersion or spraying, the bundle being cut from the drum, which is slotted for this purpose, and allowed to drain until the liquid content is 100 per cent on the weight of the filaments. The filaments are centrifuged, dried either naturally, by heat, or in vacuo, and then opened, scutched and carded. The filaments may, preferably before being stapled, be subjected to a crinkling operation by boiling or steaming or by the chemical treatment described in Specification 165,164, [Class 120 (iii), Yarns &c.]. Any wetting liquid which does not deleteriously attack the filaments may be employed, preferably water, to which may be added a wetting agent, e.g. Turkey red oil or other sulphonated oil ; the wetting liquid may also contain fugitive colouring matter, and hygroscopic bodies which remain on the filaments after drying. Specifications 357,565, [Group IV], 387,003, and 387,004, also are referred to.
