Title: Improvements in or relating to electric resistance welding machines
IPC: B23K11/06
Filed: 1943-11-17
Abstract: 566,677. Welding. WRIGHT, J. A., and METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. Nov. 17, 1943, No. 19198. [Class 83 (iv)] In a resistance spot seam welding machine, particularly for welding aluminium or alloys thereof, a resilient coupling is incorporated in the drive between the source of power and the electrode wheel. When the work is moving through the machine, but without the welding current flowing, the resilient member is tensioned torsionally to some relatively small extent for transmitting the torque for feeding the work, but immediately the welding current flows the coupling is called upon to transmit a higher torque due to the electrode sinking into the surface of the work, so that the rotation of the driven shaft and thus of the electrodes is slowed down relatively to the driving shaft or stopped during each welding period, the driven shaft for a short period after each welding period rotating faster than the driving shaft and then resuming the normal feeding speed. The electrode wheel 2 may be driven from a motor 1 through reduction gear 4 and shaft 5 provided with a flexible coupling 6 for accommodating misalignment and connected to the driven shaft 8 through the resilient coupling 10. This may consist of a helical spring 12 having its ends engaged in notches 13 in end discs 11 on the shafts 5, 8, or may consist of a resilient slim portion between the shafts 5, 8, which may be integral with these shafts and produced by reducing the diameter thereof to produce this portion. Further forms may consist of a spiral torsion spring engaged by pegs on the discs 11 or by short helical springs 18 cushioning interfitting projections 17 on the discs 11.

Abstract: 851,448. Tube walls for combustion chambers; generating combustion products under pressure. ARMSTRONG SIDDELEY MOTORS Ltd. June 16, 1958 [June 21, 1957], No. 19541/57. Class 51 (1). [Also in Groups XXVI and XXVIII] In a combustion chamber of the kind bounded by a plurality of longitudinallyextending tubes the side walls of which abut those of adjacent tubes and are united thereto, at least one of the abutting pair of side walls of two adjacent tubes is formed externally with a groove which co-operates with the other wall of the abutting pair to provide a through-way. The latter may be open to the combustion chamber at both ends, or each end may be open to the exterior of the chamber, or the ends may be open to the interior and exterior respectively of the chamber. As shown, the wall of the combustion chamber of a rocket motor is formed from tubes 4, the abutting faces of which are grooved to provide longitudinal ducts 17. Alternatively, only one abutting face may be grooved. The duct proper may, alternatively, be constituted by a pipe carried by the groove or the co-operating grooves. Hydrogen peroxide flows from an inlet pipe 11 to an annular supply passage 12 connected through openings 13 to alternate tubes 4 which extend to an annular header 14 at the outlet of the nozzle 3, and returns in intermediate tubes to a chamber 15. From the latter some of the hydrogen peroxide passes through a catalyst unit 16 to be decomposed therein and afterwards mixed with fuel, supplied via a pipe 8, in a combustion region 1. The remainder of the hydrogen peroxide flows through the ducts 17 and is discharged therefrom in the region of the throat 2 to effect cooling thereat. In modifications the upstream ends of the ducts are positioned respectively between the catalyst unit 16 and the fuel distribution plate 9, and downstream of the latter. In a further modification the ducts convey fuel from an external annular fuel header to a fuel distribution pipe situated downstream of the plate 9. In yet a further modification, the ducts communicate between two external annular headers, situated on either side of the throat region, to convey additional coolant to the wall of the latter.

IPC: G01B3/11
Filed: 1967-04-27
Abstract: 1,205,234. Gauging. NATIONAL RESEARCH DEVELOPMENT CORP. 23 April, 1968 [27 April, 1967], No. 19578/67. Heading B3B. [Also in Divisions G1 and G2] Apparatus for measuring long distances comprises a drum 1 having a screw-thread 3 in which a wire 2 is wound, a spring motor 10 applying a torque to the drum tending to wind the wire, guide pulleys 11, 12 and a device 15 for accurately measuring rotational movements of the drum. The apparatus is applicable to the indication of the movement and/or position of slides or the like of machine tools and the wire has a maximum extension of fifty feet. A lead screw 7 is coupled to the drum shaft 9 by a chain 8 and moves a carriage 6 having pulleys 4, 5 to ensure that the contact point between these pulleys is aligned with the point on the drum from which the wire is being withdrawn. Rollers 13, 14 prevent the wire leaving the pulleys and a system of rollers 17-19, around which the wire is led, correct for errors due to the changing distance between the pulleys 4, 5 and the pulleys 11, 12 as the carriage 6 moves along the lead screw. The device 15 indicates each 0À002 inch movement of the wire extended from the rollers 11, 12. Each movement is fed to a counter (not shown) to store and indicate the drum rotation. Errors such as those due to the elasticity of the wire and the catenary position of the extended portion of the wire are compensated for in a modification by an arm attached to the carriage 6. The arm has a cam follower which rides on the surface of a compensating bar. Also, the device 15 is replaced by a radial diffraction grating rotated by the drum shaft 9. A system comprising a light beam and a light-sensitive signal generator which receives the light beam modulated by the cooperation of the grating and a fixed grating produces electrical signals in phase with the passage of MoirÚ fringes across the optical axis of the system on relative movement between the gratings. The signals from the system are converted into electric pulses and counted by a conventional counter. An encoder disc or cooled plate may be used in place of the grating.
