[Also in Division G3] In a welding apparatus (not described) a wire electrode is advanced by a D.C. electric motor 12 with a shunt field winding 12c, the motor having an automatic speed control. The motor may be compound wound; its armature 12d is energized through a thyristor 13 from an unsmoothed rectified A.C. supply provided by avalanche diodes D 8 -D 11 . A speed setting voltage derived from RV 1 ; a voltage across R A  proportional to armature current and the armature voltage are compared at the base of a transistor T& 3 , a resultant speed error voltage appears across a capacitor C 6 . A transistor TR 1  is arranged to conduct when the armature voltage falls to remove the speed setting voltage and similarly a transistor TR 4  shorts the capacitor 6 so that the voltage on capacitor 6 varies periodically with the half waves of the A.C. supply. When, in each half cycle, the voltage rises above that on the base of a transistor TR 5  this regeneratively switches to its conducting state applying a pulse to transformer W 1=2=3  to fire the thyristor; transistor TR 5  is reset by transistor TR 4  becoming conducting.

Patent GB-1107837-A (GB)
Title: Process for the production of expanded plastics
IPC: C08J9/12
Filed: 1965-08-27
Abstract: Expanded plastics are obtained by introducing a thermoplastic material in the form of large surface area crumbs containing a solvent or swelling agent into a mould adjustable to different volumes by means of a ram, closing the mould by the ram so that it remains gas-tight, introducing a gas into the mould in the quantity required for expansion of the thermoplastic material, at which stage the gas pressure in the mould is not high enough to cause all the gas to dissolve in the thermoplastic material, then reducing the volume of the mould by movement of the ram and gelatinizing the thermoplastic material by means of heat to form a composition in which practically all the expanding gas is dissolved, cooling the composition, relieving the pressure, releasing the composition from the mould and expanding it by reheating, wherein a solvent or swelling agent in vapour form is added to the gas before it is introduced into the mould and the amount of solvent or swelling agent in the gas is regulated in such a way that the concentration of the solvent or swelling agent in the atmosphere surrounding the thermoplastic material does not reach saturation point at any stage during the introduction of the gas.  Specified thermoplastic materials are vinyl chloride homopolymer and copolymers with vinyl acetate or vinylidene chloride.  Suitable expanding gases are hydrogen, nitrogen or carbon dioxide and suggested solvents or swelling agents with gas dissolving properties and which boil at temperatures lower than 160-170 DEG  C., are acetone, methyl ethyl ketone, butyl acetate, cyclohexanone and furan.  The usual plasticisers (e.g. di-octylphthalate or adipate) and stabilisers (e.g. lead stearate) for vinyl chloride polymers may be used.

Abstract: 769,727. Magnetic recording erasing apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 23, 1954 [Dec. 31, 1953], No. 37168/54. Class 40 (2). Apparatus for establishing a uniform unsaturated magnetic condition on a magnetic tape 3, e.g. for use in a binary recording system, includes an erasing head 7 comprising a threebranch single magnetic core assembly having two non-magnetic gaps 11, 12 of unequal length, and means for moving the tape 3 past the gaps in such direction that any given portion bridges first the shorter gap 11 and then the longer gap 12, so that by energization of a coil 13 carried by the central core branch 8 the tape is subjected first to a saturating flux of one polarity which causes its magnetization to pass from 19 to 17 in Fig. 2, and subsequently to a non- saturating flux of opposite polarity which reduces its magnetization from 17 to 16. On leaving the head the tapes magnetization falls further to a point 20. The central core branch 8, of inverted T-shape, is disposed between a pair of inverted somewhat L-shaped side branches 9, 10 to form two parallel magnetic circuits interrupted by the gaps 11, 12, and each core is embraced by a frame 14 against one leg 14a of which it is clamped by a clamp member 15 engaged by a screw 16 in the other frame leg 14a. In addition to the head described there may be provided one or more further heads, each successive head being designed to carry the tape through a hysteresis loop which is smaller than that effected by the preceding head, thereby resulting in a more complete demagnetization of the tape. Specification 678,341 is referred to.
