Title: Improvements in over-speed protection for electric motors
Inventor: PECK PHILIP ELWORTHY
IPC: H02H7/093
Filed: 1955-09-19
Abstract: 835,007. Control of D.C. motors. BRITISH THOMSON-HOUSTON CO. Ltd. Sept. 18, 1956 [Sept. 19, 1955], No. 26747/55. Class 38 (3). A motor 2 is protected against over-speeding by means of a circuit-breaker 4 having a tripcoil 12 which is energized when a relay 16 closes contacts 15. A coil 17 of the relay responds to the voltage of an exciter 6 for the motor, whilst a second relay-coil 18 is energized by a motordriven tachometer generator 19. A bridgetype rectifier 20 ensures that the energization of coil 18 is the same for either direction of rotation of the motor, and is in a correct sense to combine with the energization provided by coil 17 when the exciter is operating to reduce the motor-field. The protection afforded thus anticipates conditions in which over-speeding is likely to occur and guards against such overspeeding. The exciter 6 has a field winding 7 for determining the excitation of the motor, and an opposing field winding 9 which is energized from magnetic amplifier 10. A control winding of the amplifier is excited in accordance with the output current of the machine 6. The motor may be supplied from a Ward-Leonard generator 1.

Abstract: 816,217. Work-holders. QUASI-ARC Ltd. Sept. 20, 1956 [Sept. 20, 1955], No. 26815/55. Class 83 (3). A welding-positioner comprises a turntable 1 tiltable from the horizontal to the vertical plane, the table being in its lowest position when horizontal and raised to higher levels during tilting. The table 1, table-rotating electric motor 16, and gearing 17 are mounted on the parallel bars 10 of a pair of four-bar kinematicchains 5, 8-10 arranged side-by-side, the bars 5 forming part of the stationary framework 3, 4 of the positioner to which the bars 8, 9 are pivoted at 11, 12. Screw-jacks or, as illustrated, one or more fluid-pressure jacks 19, 23 simultaneously raise and tilt the table from the horizontal, through the outer dead-centre position of the bars 9, 10, to the vertical and then to the 135-degree face-down position depicted in broken lines. A single-acting jack 23 is connected to each pivot 12 and the adjacent bar 8, and the double-acting jack 19 is pivoted at 21 between the frames 3, 4 and at 22 to a member connecting the bars 9, the jacks 19, 23 acting together to raise the table, but the jacks 23, acting as dash-pots, opposing the jack 19 as the table is lowered to the horizontal, or passes beyond the dead centre of bars 9, 10. Fluid-pressure control.-Fluid, drawn from a reservoir 32, Fig. 4, by a pump 30 driven by an electric motor 31, Fig. 1, is delivered through a relief valve 40 to three three-position valves 34, 36, 35, valves 34, 36 being hand-operated and linked mechanically, and valve 35 being returned by spring pressure to the central setting, in which the jacks 23 are locked. Setting of the valve 35 in its other two positions is controlled by the valve 36 and a two-position valve 37 which crosses the pressure and return control lines from the valve 36 to valve 35, and thus changes the setting of valve 35, when the bars 9, 10 are passing through the dead-centre position. The two ends of valve 37 are connected to spring-return valves 38, 39, operated by cams, (not shown) on the linkage as the bars 9, 10 pass through the dead-centre position, the valves 38, 39 being connected to the feed-lines for the jack 19 so that although both are actuated at top-dead-centre, the impulse received at valve 37 is that from valve 38 or 39, corresponding to the direction of movement of the ram 19. Exhaust lines are shown in broken lines and that from the jacks 23, through valve 35, passes through an adjustable metering-valve 33 to control the rate of descent of the table. The Provisional Specification describes also a construction in which only two fluid-pressure jacks are used, the double-acting jack being connected to one side of the base and the single-acting jack to the other.

Group XXV] An eyelet E, Fig. 9, is made pressing a metal pellet 2, Fig. 1, in a die cavity by means of a punch 4 so as to cause rearward flow of metal over the punch to form the barrel 16 and forward flow to form a head flange 20 which is of concavo-convex shape in radial cross-section. The pellet 2 is of light alloy and may be cut from a bar or may be formed by upsetting as disclosed in Specification 728,951. The die cavity is formed between separate die members 8, 10 and the member 8 is raised after formation of the eyelet, Fig. 5 (not shown), to permit the upward ejection thereof after the insertion from below of a new pellet. A web 22 is left between the punch and die and is subsequently removed by punching out. A bead 38, Fig. 9, is formed on the inner edge of the head flange; the amount of metal forming this bead may vary between different eyelets dependent upon the volume of the respective pellets and thereby length variation in the eyelets is minimized. The punch 4 has an undercut tip portion 46, 48 which initially forms the barrel 16 with a tapered wall, Fig. 6 (not shown) but on withdrawal of the punch the barrel is drawn out to substantially uniform wall thickness. The lower end of the punch tip terminates in a scalloped edge 54, Fig. 1, which forms four, five or six scallops 56, Fig. 9, at the tail end of the eyelet. The tail end may alternatively be flat. The head flange of the eyelet is subsequently dipped in celluloid lacquer to provide an ornamental coating. Specifications 737,161 and 737,259, [Group XXV], also are referred to.
