Title: Improvements in and relating to arc welding systems
IPC: B23K9/12
Filed: 1934-09-17
Abstract: 427,863. Arc - welding systems. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. Sept. 17, 1934, No. 26688. Convention date, Sept. 19, 1933. [Class 39 (iii)] In an automatic arc-welding system the electrodes 30, 31 are initially connected to the supply mains 3 through a high impedance and are afterwards connected to the mains through a low impedance coincident with the separation of the electrodes to strike the arc, and the operating speed of the feeding means is reduced after contact of the electrodes. The high impedance consists of the operating coil of the switch 18 and the speed reducing means consists of a shunt 60 to the armature circuit of an electrode feed motor 6 with oppositely wound fields 53, 66 selectively energized under the control of a switch 7 and relays 9, 10, in accordance with a characteristic of the arc. When switches 16, 14 are closed the coil of switch 17 is energized from source 11 to close the switch and connect the electrodes 1 to the mains through the high impedance. Coil 8 is thus energized from source 11 to cause operation of the motor 6. When the electrodes contact the switch 18 is closed. Closure of contacts 55 causes closure of switch 4 to connect the electrodes to the mains through the low impedance 19. Closure of contacts 56 inserts the shunt 60 in the armature circuit of the motor 6. Closure of contacts 57 short-circuits a protective resistance 61 in the circuit of coil 8. An impedance 20 may be inserted in the welding circuit in parallel with impedance 19, to increase the welding current, by closing switches 22, 24. The relative position of the electrodes may be controlled by hand by means of switches 12, 13. A plurality of similar welding systems may be connected to the same supply sources the switches 16, 24 forming master controls.

Patent GB-615731-A (GB)
Title: Improvements in or relating to abrasive articles
IPC: B24D3/08
Filed: 1945-10-17
Abstract: In an abrasive article, e.g. a grinding or lapping wheel, in which diamond particles are bonded in a sintered metal or alloy, smearing of the bond metal over the diamonds, and welding of particles abraded from the work piece, to the bond, are prevented by adding one or more of graphite, talc, soapstone, slate and molybdenum sulphide to the bond metal powder.  The metal bond may include copper, bronze, brass, zinc, nickel, iron, the substance known under the Registered Trade Mark "Monel Metal" and hard metals such as tungsten carbide.  The diamond particles may be coated by a metal film as described in Specification 614,396, [Group XXII], prior to being mixed with the metal powder and the graphite &c. powder, and pressed in a die with or without heat. The diamond-containing powder may be pressed with a layer of metal powder containing no diamonds, the whole then being sintered.  A backing of metal or plastic can be attached by known methods, or the backing may be formed of pressed metal powders.  As an example, a bronze powder (10 per cent tin) or an equivalent amount of powdered copper and tin, is added to 2 to 3 per cent (not more than 5 per cent) by weight of powdered graphite and 15 to 40 per cent (not more than 60 per cent) by volume of diamond powder.  The mixture is spread evenly on the bottom of a steel die set, and is covered with a thicker layer of bronze powder containing no abrasive, but containing an inert material so that the shrinkage of the layer is decreased to that of the diamond-containing layer, thereby avoiding distortion during sintering.  Alternately the composition of the metal powder can be chosen to obtain the correct shrinkage.

Abstract: 908,490. Mass spectrometers. BENDIX CORPORATION. Aug. 8, 1960 [Aug. 17, 1959], No. 27439/60. Class 39 (1). In an arrangement for collecting a pure stream of charged particles, e.g. for mass analysis, the particles are given a bodily movement in one direction to form a stream and are then accelerated at an angle, e.g. 90 degrees, to the first direction to be collected exclusively on or around the resultant direction followed by the particles; any residual stray particles within the arrangement and which do not receive the bodily movement given to the charged particles are not collected. In the time-of-flight mass spectrometer of Fig. 1, particles evaporated from a " boiler " 20 are ionized by an electron beam from a beam source 29. The ions formed are accelerated transversely of their original direction by a pulsed accelerating field applied between grids 28 and 30 to follow a resultant path 32 to the collector 38. Stray particles follow the path 34. The collector 38 is connected to an electron multiplier 39 such as described in Specification 835,129. The direction of the accelerated ions may be changed by a pair of deflecting plates located between the accelerator grid 30 and the collector 38. The deflecting field may be varying to compensate for differing energies of  the ions. In Fig. 5, the accelerating grids 54, 56 have offset central openings and a magnetic deflecting and concentrating field is provided by a pair of magnetized plates 62 connected together by a plurality of bar magnets. A varying magnetic field may be used or the magnetic field of Fig. 5 may be combined with the electric deflecting field in the modification described above in connection with Fig. 1. The mass spectrometer may be mounted on a rocket or artificial satellite and the bodily relative motion of the charged particles due, at least in part, to the motion of the moving body.
