Title: Welding apparatus
IPC: B29C65/02
Filed: 1955-11-24
Abstract: In a flame-welding machine having a welding unit and a tracing unit rotatably supported on spaced axes normal to a work plane and linkage interconnecting the units for moving them simultaneously along parallel paths, rotation of the tracing unit about its axis effects an equal rotation of the welding unit.  The machine is particularly adapted for forming weld joints of lead, but may be used for coating, e.g. steel plate with lead, or for applying fusible material such as organic thermoplastic resins.  As shown, a trolley 195, Fig. 9, in which the tracing unit 196 is rotatably mounted runs on rails 211 mounted on a carriage 214 movable along fixed transverse rails 217, 218.  The welding unit 31 has a frame 57 carrying wheels 65 arranged to run on the workpiece and a supporting shaft 175 rotatably mounted in a block 178 on a threaded rod 179 journalled in a gear carried by an arm 194 secured to the trolley 195.  Rotation of the shaft 197 of the tracing unit 196 varies the setting of a potentiometer 205, Fig. 11, forming part of a bridge circuit.  The unbalanced current is detected by a double-acting relay 193 which connects up a reversible shaded pole-type motor 187 to rotate the shaft 175 of the welding unit and the arm 185 of a potentiometer 186 until the bridge circuit is balanced and the relay 193 released.  A container 56, Figs. 5 and 7, charged with pieces of lead is heated internally by an electric heater 148 or externally by a gas burner to melt the lead.  The container 56 is reciprocatably mounted in the frame 57 and carries an electric motor 67 driving a camshaft 71 and a gas torch 110.  The camshaft 71 is driven continuously and carries cams or eccentrics which through a pawl and ratchet mechanism 138 intermittently rotate the wheels 65, reciprocate the container 56 transversely of the frame 57, lower the torch 110 during the forward movement of the welding unit 31 and momentarily lift a valve 92 to release molten lead at an instant halfway through the advacing movement of the welding unit 31 at which time the container 56 is centred relatively to the frame.  A radius arm rotatable about a fixed pivot may be secured to the shaft 197 if circular welds are to be performed.  In a modification, Fig. 1, the welding and tracing units 31, 30, respectively, are secured to a pantograph supported on a fixed rod 4.  The effective <PICT:0797020/III/1> <PICT:0797020/III/2> <PICT:0797020/III/3> <PICT:0797020/III/4> <PICT:0797020/III/5> lengths of the arms of the pantograph are adjusted by rotating gears 18 and 34 to turn screwed rods 22 to move the pivot points 10, 11 relative to the arms of the pantograph.  The shafts 169, 46 of the tracing and welding units 30, 31, respectively are connected to the armatures of motors 15, 47 forming part of a selsyn transmission so that movements of the shaft are synchronized.

Patent GB-433369-A (GB)
Title: Improved method of and apparatus for the automatic control of a physical condition
IPC: G05D23/12
Filed: 1933-12-06
Abstract: 433,369. Fluid-actuated valves. KENT, Ltd., G., 199, High Holborn, London, IVANOFF, A., and HOWARD, G. P. E., Biscot Road Works, Luton. Dec. 6, 1933, No. 34303. [Class 135] In apparatus for restoring to a predetermined value, a variable physical condition such as temperature, pressure, flow or velocity, a control effect is applied to the regulating device which is dependent both upon a displacement dependent on the rate of change of the condition, and upon a velocity dependent upon the deviation of the condition from the predetermined value. The rod 45 which moves in accordance with the deviation of the condition, turns a bell-crank 43 about a pivot 44, the angular position of which controls the output speed of an infinitely variable-speed gear which is reversible. This gear drives a spindle 56 so that the arm 55 moves at a rate dependent upon the deviation. This motion is given to a link 58 connected to a control valve or other control device by means of a floating lever 53 which is moved by the arm 55 about its connection to a link 52. The bell-crank 43 is also connected by a link 46 to a floating lever 47 pivoted at 47<1> to a lever 48, in turn pivoted to the link 52. The angular position of the fixed pivot 49 of the lever 48 controls the output speed of another infinitely variable-speed gear of the reversible type. This speed gear drives an arm 51 connected by a link 50 to the lever 47, about a pivot 51<1>. If the condition is changing at a constant rate, the lever 48 takes up a definite position because the motion which would be given to the pivot 47<1> by the link 46 is nullified by that which would be given to the pivot 47<1 >by the arm 51 and link 50. In the construction shown, the pivotal connection of the link 50 with the lever 47 moves with twice the speed of the pivotal connection of the link 46 with the same lever. If the rate of change of the condition increases to a higher constant valve, the lever 48 re-adjusts itself so that the speed of the arm 51 and the link 46 combine to render the pivot 47 stationary but in a new position. If the deviation remains constant (i.e. its rate of change is zero), the speed gear through the arm 51, link 50 and lever 47 merely returns the pivot 47<1> to its zero position. Thus the displacement of the pivot 47<1> and hence of the link 52 depends upon the rate of change of the deviation. This displacement is applied to the control link 58 through the lever 53 and thus acts jointly with the velocity imparted by the arm 55.

At the opposite end of the machine the inlet I is arranged close to the end cover if ordinary connectors are used at that end of the, rotor, but connectors G<2> similar to the connectors G, and of smaller resistance, may be provided and cooled by air either from the inlet I as shown, or from a special inlet in the end cover at that end of the machine, the air leaving by an outlet J<2>. In the construction shown in Fig. 4, air from an inlet I first cools the windings &c. and is then divided by the partition F into two streams, one of which cools the end connectors G, and the two streams leave by outlets 0, J. In the consruction shown in Fig. 6, both ends of the machine are arranged similarly and the air inlets I<2> are placed centrally.

Abstract: 870,235. Cathode-ray tubes. ELECTRIC & MUSICAL INDUSTRIES Ltd. Oct. 28, 1957 [Nov. 14, 1956], No. 34765/56. Class 39(1). In a method of making a mosaic electrode in which material, subsequently converted b y oxidation to a caesium resistant metallic oxide, is first deposited on a surface 4 through a mesh 6 spaced from the surface a n d conducting material is then deposited with the mesh in contact with the surface, the first material is evaporated from a source 12 not only in the direction of the surface but towards the envelope and re-directed from there on to the surface so that areas of the surface opposite the bars of the mesh are also effectively covered. The envelope is heated at 15, or by eddy current heating of the wall anode 9 to reflect or re-evaporate the material. The first material deposited may be magnesium. The quantity of magnesium deposited may be measured by observing the quantity deposited on a relatively cool part of the glass wall, leaving a small gap in the heating element for this purpose, or a known weight of magnesium may be evaporated at a known distance from the surface. The envelope wall is heated to between 300‹C and 500‹C. The mesh is then electrostatically attracted to the surface and the conducting elementsformed, e.g. from an alloy of bismuth and silver. The mesh is then moved to a position in which during operation of the tube it acts as a stabilizing electrode. The conducting elements are finally caesiated. Specifications 686,465 and 740,751 are referred to.
