Title: Automatic copying milling machines
IPC: B23Q35/20
Filed: 1954-05-14
Abstract: 816,471. Copy-milling. ARMYTAGE, F. W. Aug. 12, 1955 [May 14, 1954], No. 14128/54. Class 83 (3). A profiling-machine, such as for machining a turbine wheel with an end-mill, comprises an hydraulically-operated tracer 40 and a cutter 37 traversed in paths transverse to the paths in which a template 34 and a workpiece on a shaft 18 are rocked in unison by an hydraulic ram 13 controlled by the tracer. The tracer and cutter may be connected by a pantograph and traversed hydraulically, or by a screw 43. The template is radially adjustable on an arm 6 of a disc 5 connected to the ram 13. The disc 5 is freelymounted on a shaft 1, to which is keyed a drum 16 and a gear connected to rock the work-shaft 18 in a ratio corresponding to that of the pantograph. The disc 5 is connected to the drum 16 by one of two dogs 26 on an arm 8 of the disc, which dogs may be operated manually or automatically by levers 30 to index the drum after each oscillation. A friction-clutch 52 acting as a brake prevents slipping when the disc and drum are disengaged, for indexing to take place. The indexing is effected either by a cam on the template causing the tracer to rock the drum, or by a handle 51. In a modification, the template is replaced by an indexing-template and a scale replica of the work which is indexed with the work. In a further modification, the workpiece 63, Fig. 6, is mounted coaxially with an indexing-plate 64 engaged by a bolt 69, and the template is universally adjustable on a holder 70.

Abstract: 623,914. Control of A.C. motors; electromagnetic switches. ENGLISH ELECTRIC CO., Ltd., DONALDSON, C. S., and PEARSON, E. May 28, 1947, No. 14193. Addition to 603,515. [Classes 38(iii) and 38(v)] In the A.C. motor-starting device described in the parent Specification the movable ferro-magnetic member is provided with biassing means which exert a force, decreasing with an increase of distance between the ferro-magnetic members, and opposing the repulsion force between said members due to the energization of the operating coil The movable ferro-magnetic member 5 is supported on a spring 2 the centre limb 2b of which is pivoted in a groove 3 in the boss 1b formed on the fixed ferro-magnetic member 1. The two outer limbs 2c of the spring are pivoted in a lower notch 4, the centre limb being under compression and the two outer limbs under tension. A case 6 is provided having a lid 7 to which is attached two spring strips carrying contacts 11 which co-operate with contacts 12. The contacts 11 and the supports therefor are arranged to prevent the spring 2 from reaching its dead-centre position. The whole assembly is located within the operating coil 16 which is placed in series with the motor running winding, the contacts being serially connected to the motor starting winding. A lip 1a of the member 1 directs the magnetic field as the member 5 is deflected so as to assist in obtaining the maximum repulsive effort. With the arrangement shown in Fig. 4 the whole of the switch mechanism is carried on the fixed ferro-magnetic member 22. The movable ferro-magnetic member 31 is carried on a spring 20, which is similar to the spring 2 and has its movement limited by a screw 21. With the members 31 and 22 engaged, a ferrule 30 engages the spring 20 and prevents closure of contacts 23 and 24. When the member 31 is repelled, a spring 25 closes the contacts. An aluminium block 27 dissipates heat from the contact 24. In modifications, the two outer limbs or the centre limb of the spring which carries the movable ferro-magnetic member are supported in cantilever fashion on the fixed ferro-magnetic member; the other respective limb or limbs being pivoted on an adjustable screw in the fixed member.

Patent GB-456827-A (GB)
Title: Improvements in or relating to two-way telephone transmission systems or repeaters
IPC: H04B3/20
Filed: 1935-05-16
Abstract: 456,827. Two way transmission. STANDARD TELEPHONES & CABLES, Ltd., and LATIMER, K. E., Connaught House, Aldwych, London. May 16, 1935, No. 14406. [Class 40 (iv)] The input of a voice-operated detector controlling directional switching in two-way systems is associable or associated with two points in the transmission paths, one point being effective before switching occurs, and the other after. In the system shown in Fig. 4, the lower (E-W) path is operative and a detector is associated with each of the points AD1, AD3. On arrival of speech from W, the detector at AD1 receives more energy than that at AD3, and a differential switching device represented by contact a makes the W-E path and breaks the E-W path. The switching device also causes the detector at AD1 to be changed over to AD2 and that at AD3 to AD4, where AD2 receives more energy than AD4 and maintains the circuit conditions until speech from E arrives and causes AD4 to preponderate over AD2 to reverse the switching devices. The switching arrangements are shown in Fig. 3 in which the input points connected to amplifier-detectors V1, R1 and V2, R2 are controlled by contacts of relay B. Speech from W changes over differential relay DR which operates a quick relay A to switch over the transmission paths, and energizes the slow-to-operate relay B to switch over the input connections of the detectors and to operate a further slow relay C which opens a circuit holding DR during the switching operations. As the amplifiers VI, V2 receive more energy after switching than before, correct operation in the overloaded condition is provided for by a biassing circuit GB. On overloads, the condenser charges up owing to flow of grid current to apply a negative bias and the valve to which the greatest energy is applied has an output while the other is completely jammed. This bias circuit also provides a hang over time after a loud syllable. Another arrangement, which is not so advantageous, is shown in Fig. 2, where the points AD1, AD4 are on the output side of the amplifiers Al, A2. Attenuators P1, P2 are necessary to prevent false operation by echoes unless the hybrid balance is good. The pads could be omitted if one detector associable with AD1, AD4 were less sensitive than the other associable with AD2, AD3, and the outputs of the detectors were changed over when switching over the inputs. Another modification, Fig. 5, uses hybrid coils or attenuation networks H3, H4 for associating each of detectors at 1, 2 with two points AD1, AD2 and AD3, AD4, in the circuit, the hybrid coils or attenuators preventing any substantial feed-back from the outputs of the amplifiers A1, A2. In a further modification, suitable for music transmission circuits where only an occasional reversal of direction is necessary, a common amplifier is switched for use in either direction.

Abstract: 497,632. Electric welding; planing- tools. STEVENS, A. H. (United Engineering & Foundry Co.) May 17, 1938, No. 14678. [Classes 83 (iii) and 83 (iv)] Metal strips are joined end to end by first butt-welding, then moving the strips into and clamping them in a flash - trimming position, and then bringing a flash trimmer into contact with one strip and moving it over the strips so as to sever the flash therefrom. The strips from the rolling mill may be fed by rolls 18 over conveyers 16, 17. The leading end and trailing end of the respective strips are severed at the same angle either separately or simultaneously by shearing apparatus 10. The strip ends are then held between the air-operated clamps 20, 22 of an electric flash welding apparatus and welding effected by moving one or both of the clamps by air motors. The welded strips are then fed to the flash trimmer and are held by air-operated clamps 50. The trimmer consists of a pair of straight, curved, or V-shaped cutters 40 brought into position' by air motors 42 and moved over the joint by air motors 46. Each cutter has a pair of opposed knife edges so that the flash may be removed in either direction of movement of the cutter or so that the cutters may be turned end for end to present a fresh cutting edge when trimming only in the direction towards the welding apparatus. In a modification, Fig. 2, in which the strips are unwound from a reel 66 and wound on a reel 68, the parts are similarly cut and welded by mechanisms 60, 62 and are then clamped by the welding jaws 72, 74 and the trimming effected by moving the trimmer 94 in a direction away from these jaws. In both cases the trimmer may thus move from the thicker trailing end to the thinner leading end, the ends in the second form having been reversed due to winding on the reel 66. When operating on softer metals or where the difference in thickness between the ends is small, the trimming may be effected from the thinner to the thicker end.
