Abstract: 1,217,565. Arc welding systems. LINCOLN ELECTRIC CO. 8 July, 1968 [10 July, 1967; 20 June, 1968], No. 32447/68. Heading H2H. The power supply for an arc welding system wherein an arc x is maintained and a droplet on the end of an electrode periodically contacts a weld pool, includes first and second D.C. power sources G and S, supplying the workpiece and electrode, in parallel. The first source has a short-circuit current note of rise less than 60,000 (preferably between 15,000 and 40,000) amperes per second and a voltage output sufficient to maintain an arc between the electrode and workpiece for drop formation. The second source has a short-circuit current rate of rise in excess of 60,000 (preferably between 100,000 and 1,000,000) amperes per second and a voltage output such as to supply substantially no current when an arc exists and a pulse of current when the droplet still on the end of the electrode contacts the weld pool. As shown, the workpiece W and motor-driven electrode E are connected to respective terminals CT, CP to which the first and second sources, G and S, are connected. The second source is an alternator A on the same shaft as the first source generator G, the alternator being connected through a three-phase rectifier bridge 41. The generator G is controlled by a settable voltage regulator R which can be connected to the terminal CT, CP and controls the field windings 33 of the generator G. The regulator R can also be connected across a resistor 44 in the field winding circuit when the second source S is disconnected. Alternatively the first source G may be batteries with an inductance or rectified A.C. supply with an inductance of D.C. from a rotating generator with or without an external inductance. The second source S may also be a battery or current transformer with a rectifier.

Title: Method of and apparatus for the manufacture of concrete pipes by moulding
IPC: B28B21/24
Filed: 1948-12-24
Abstract: Apparatus for centrifugally moulding and lining concrete pipes, is of the type comprising a supporting framework having means for locating a vertical mould in axial alignment with a vertically reciprocating and rotating piston or packer having packing elements, and means for moving the piston up and down so that it traverses the mould from the bottom to the top, the piston and its associated parts being counterbalanced.  In the apparatus of the invention, Fig. 2, the piston is mounted on the upper end of shaft 12 which is carried within an outer sleeve 12a, the shaft being rotated by the motor 13 through a belt drive 17.  The supporting structure 16 has rollers 18 which run on vertical parts of the frame.  The piston assembly is vertically lifted by a reversible electric motor 19 driving through automatic change speed and reverse gearing a cross-shaft 20 counterbalanced by weights 23, (see Group XXIV).  With this arrangement overdrive is prevented.  The mould support consists of a floor plate 43, and an upper supporting tray 45 with a mould retaining ring on its underside.  The tray is guided at each side and may be raised or lowered by means of a lever 51, rods 50 and counter-balanced bars 59.  The tray has a plate 47 arranged to receive a cylindrical pipe socket former which may be rotated by an electric motor 77. The table may be freed by movement of a lever 54 which causes the adjustable stops 53 to swing rearwardly, thereby enabling the table to rise and so allow the insertion or removal of the mould. The piston wall, Figs. 4, 5, is preferably built up from wear resisting metal strip 62, and packing elements 63 are mounted on the piston crown, each element consisting of a blade pivoted on a spindle 64.  The blades are coupled together through a toggle mechanism 67, 68, to a vertical actuating rod 65 which passes through the centre of the piston and its driving shaft and is freely movable with respect thereto so that the rod may be lowered or raised by a lever 71, Fig. 1, (not shown), to open or retract the blades, the end of the lever being arranged to engage adjustable stops 73, 74, during the process.  In operation the body of the pipe is first moulded and then the lining material which may consist of sand and cement with or without fillers such as powdered glass, carbon &c. is fed on to the piston crown.  The motor 19 then raises the piston with the blades open or <PICT:0661289/III/1> <PICT:0661289/III/2> <PICT:0661289/III/3> projecting so that the material is wiped into the soft surface of the pipe body, at the same time further compressing the body.  The socket of the pipe however is not lined. When the head of the piston is clear of the former the blades are retracted by the engagement of the lever 71 with the stop 74, the motor 19 is automatically reversed and the piston returned at a faster speed to smooth the lining.  Specification 661,290, [Group V], is referred to.
