Title: Improvements in and relating to gramophones
IPC: G10K13/00
Filed: 1920-10-02
Abstract: 173,838. McQuinn, J. Oct. 2, 1920. Sound magnifying and directing appliances.-Relates to gramophones of the kind described in Specification 121,336, in which the tonearm is connected to a guide tube slidable in bearings, so that the needle travels in a radial line across the record disc, and consists (1) in providing at the junction of the tone-arm and guide tube a rotary valve whereby the volume of sound may be adjusted, and whereby the tone-arm may be connected to one or other branch of the guide tube to adapt the instrument for recording or reproducing; and (2) in fitting the guide tube with detachable sleeves having felt packing rings. In the form shown, the tone-arm 11 is connected to a guide tube 2 slidable in fixed bearings 3, one of which communicates with the reproducing- horn 5 and the other with an orifice, normally closed by a, rosette 7, to which a recording horn may be coupled. At the junction of tone-arm and guide tube is a rotary valve 4, so shaped that the tone-arm may be put into communication with either branch of the guide tube and the volume of sound admitted to either branch may be regulated. The guide tube 2 carries detachable sleeves 9 fitted with renewable felt rings 8 which slide in the bearings 3.

Title: Improvements relating to the direct extrusion of metals
Inventor: HANES RICHARD
IPC: B21C35/04
Filed: 1954-09-28
Abstract: 777,362. Extruding. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Sept. 23, 1955 [Sept. 28, 1954; Jan. 31, 1955], Nos. 27967/54 and 2792/55. Class 83 (4). In the direct extrusion of metal from a billet, the billet engagement end of the extrusion punch 21 is shaped at 37 so as to key to the end portion of the billet during extrusion, whereby after separation by shearing of the discard from the extruded product, the punch together with the discard may be withdrawn from the container 5. The forward end of the punch has a dovetail slot 37 whose width increases from one end to the other, Fig. 3 (not shown), whereby after withdrawal from the container, the discard may be removed from the punch by transverse pressure. The extrusion die 7 engages within the container bore and is surmounted by a profiled ring 13 to ensure smooth flow of metal through the die orifice which, in this embodiment, is of T- shape, Fig. 4 (not shown). For severing the discard after extrusion, the punch 21 is rotated about its axis, whilst within the container bore and keyed to the discard, by means of a spanner 29 actuated by a pair of hydraulic motors 33, Fig. 6 (not shown). Alternatively the die 7 and the extruded metal remaining therein may be rotated relatively to the discard and punch 21. In another embodiment, Fig. 10, used for forming tubes of substantially square crosssection, Fig. 9 (not shown), with a square bore and using a mandrel 95 of square cross-section, the extruded product is severed from the discard after withdrawal of the mandrel by transverse movement of the bolster 73 which supports the die against a hardened steel shearing plate 83. The bolster and shearing plate are moved transversely by a hydraulic motor 77, 79. A stop 81 limits the transverse movement. The extrusion press is operated hydraulically. The process of the invention is applicable to both cold and hot direct extrusion.

Abstract: 687,919. Gasifying coke. METALLGES. AKT.- GES. Nov. 30, 1951 [Dec. 9, 1950], No. 28181/51. Addition to 676,391. Class 55 (i). The process according to the parent Specification so far as it is applied to the gasification of carbonaceous fuel, is modified in that coke is used as the starting material instead of a bituminous fuel. Any coke may be used but a reactive coke produced by carbonizing pulverulent coal by the parent process is particularly suitable. The coke is gasified with steam and/or carbon dioxide, or steam and air or oxygen enriched air, and the resulting gases, of the character of water gas, may be used for synthesis purposes. Alternatively, coke produced by carbonizing finely-ground coal in a cyclone chamber under ash-fluxing conditions may be used.

[Class 97 (i)] Perforated metal screens are built up from sheets secured together at their edges in such manner that there is no material obstruction of the perforations, and little or no area of contact between the parts of the sheets providing the display surface and any member used to support the sheets ; lack of uniformity in the reflecting qualities of the coated screen surface, and reduction of the area available for sound transmission, are thus minimized. As shown in Fig. 3, the sheets A have return edges A<1> secured together by bolts and clamping strips B. The strips B are chamfered so as to have little or no surface in contact with the main portions of the sheets. A narrow filling strip C may be fitted to render the front surface of the screen substantially continuous. The structure may be mounted on a main frame having tie rods. Fig. 4 shows a modification in which the edges of the sheets A are secured by staples to wood or other supports D having front faces forming a V to reduce the area of contact; the edges of the sheets may be butted together. According to the first Provisional Specification, the sheets may be bent along a line of perforations to form the return edges, the return edges may be welded together, and reinforcing members of T-section, or of sheet metal bent to such section, may be provided at the joints. According to the second Provisional Specification, the reinforcing members may be of U- or L-section, and the joints may be filled. with plastic material containing white lead, with a welded strip, or with a soft metal strip caulked or hammered flush with the screen surface.

The friction rod 12 for reinforcing thread guides 49 is driven by a cam 1 rotated by the main shaft, through a first order lever 5, the ratio of the length of the arms of which is variable by means of a lead screw 9 which is stationary, apart from its axial rotation. The lever 5 is slidable on a member rotatable about a pin 6 carried by a slide 7 traversible along guideways 8 by the screw 9 which is carried in stationary bearings 14, 15 and which is co-operatively connected with the mechanism controlling the thread guide stops. That mechanism is controlled either by the main control chain, or by a separate chain or disc running synchronously with the main chain. The nut coacting with spindle 9 may be rotatably mounted on slide 7 in order that the pin 6 may be moved without need for rotation of the spindle. The cam 1 is so profiled as to accelerate the thread guides over the first half of their travel and accelerate them over the second half. Fig. 2 depicts a stocking with reinforcement of varying width, which may be knitted.

Abstract: 722,188. Milling-cutters. LA SALLE STEEL CO. Dec. 11, 1951, No. 28976/51. Class 83 (3). Special processes.-A method of machining ferrous metal consists in moving a continuous series of cutting teeth having a spacing uf ¢ inch or less successively into engagement with a workpiece at a tooth travel-rate in excess of 1,000 ft./min., maintaining at least two teeth in engagement with the work at all times, and moving the work and teeth at a relative speed in excess of 90 ins./min. In milling work 16, Fig. 2, two cutters are rotated about their axes at 1,500 r.p.m. and are also rotated about the work which is fed at 50 ft./min. Each cutter has teeth pitched at “ inch and ground from a carbide body, the diameter being 4 inches. The depth of cut is <SP>1</SP>/ 32  inch. The work may be rotated and the cutters rotated about their axes only. A second form of cutter has a body 20, Figs. 5, 6, formed with slots 21, 22 into which are placed blade elements 24 having- a helix angle of, preferably, 18 degrees, and a pitch of approximately “ inch for a 12 inch diameter body. The blades are secured by a non-resilient organic plastic or metal alloy which is forced around the blades and into recesses 25, 26, the plastic or alloy being subsequently partly removed to provide chip clearance-spaces and the blades ground to the required profile. The cutter is rotated at 500 r.p.m. with a chip size of 0.005 inch and a feed rate of 375 ins./min. In a machine for using the cutter, the feed-screw was rotated at 1200 r.p.m. to give a feed of 600 ins./min., the spindle speed being increased to 1,462 r.p.m. Other performance figures for current practice and for the present method are quoted.
