IPC: B65H54/34
Filed: 1961-02-13
Abstract: 953,221. Winding transfer tails. IMPERIAL CHEMICAL INDUSTRIES Ltd. Jan. 22, 1962 [Feb. 13, 1961], No. 5222/61. Heading D1J. A transfer tail A is wound on a bobbin 6 by bring- ing the bobbin up to speed, and then allowing a projection 7 to entrain the yarn 2 and tension it so that it is stretched against a slotted guide 4 rotatable about an axis normal to that of the bobbin 6. The tensioned yarn 2 presses against one of the slots 8 in the guide 4 and causes the guide 4 to rotate until it eventually releases the yarn to a reciprocating thread guide building the yarn package. The slotted guide 4 has a high inertia so that it will rotate only slowly whilst engaged by the yarn 2 and so cause the transfer tail A to be wound during said engagement.

Title: Improvements in or relating to means and methods of magnetic and electric measurements in electrical conductors
IPC: G01N27/83
Filed: 1923-02-28
Abstract: 206,104. Western Electric Co., Ltd., (Assignees of Buckley, O. E.). Oct. 24, 1922, [Convention date]. Transformers.-A conductor, particularly a submarine cable, is wrapped spirally with wire or tape of magnetic material such as iron-nickel alloy; it is passed slowly first through a furnace and then through a cooling medium so as to give the loading-material a high permeability at low magnetizing forces; the magnetic condition of the moving conductor is constantly measured to determine whether the heating and cooling are correct. The conductor 2 is passed from a drum 1 through the heat-treating apparatus 3 and a solenoid 7 to a talce-up drum 4. An alternating current is passed through the conductor, and is measured by an ammeter 9. An alternating magnetic field is induced in the magnetic covering of the cable 2, the lines of force tending to follow the spiral line of the tape and thereby inducing an electromotive force in the solenoid 7. This is applied to an amplifier 10 and is measured by a thermo-couple 12 and a direct-current ammeter 13, thereby giving a measure of the permeability of the magnetic wrapping of the conductor 2. If the permeability of the covering is known, the apparatus may be used to measure the current flowing through the conductor, the magnetic covering serving as the core of a current transformer.

Abstract: 539,717. Gas-blast switches. REYROLLE & CO., Ltd., A., WILD, R. W., and FENN, R. W. April 3, 1940, No. 6002. [Class 38 (v)] A lateral discharge nozzle for de-ionizing gas blast comprises a back plate A and converging side plates B, B<1> of insulating material, and top and bottom conducting members D, E, which diverge from metal blocks D<1>, E<1> secured to housings G, H for the fixed contact-fingers G' and annular contact H<1> surrounding the movable rod contact J. The discharge end of the nozzle has an arc grate C provided with vents C', and the nozzle is packed with graded lumps K of boric acid, fibre, or other material which evolves a de-ionizing gas when acted upon by the arc. Such material may also be provided in the plates B, B<1>, or the latter may be serrated, so as to avoid a smooth passage for the arc clear of material and to concentrate the blast on the arc. Contact J has an arcing tip J' facing the nozzle and a gas-evolving member may either be fixed to it, as shown, or may follow it under spring action in the opening movement, Fig. 3 (not shown). The blocks D', E' and their separator F closely surround the contact J so that the arc is forced into contact with the lumps K and along, the members D, E. With low currents and hence low gas-evolution, the arc is forced against and seals the vents C<1> until adequate pressure is built up behind it. The arc-movement may be assisted by magnetic material or by electrodynamic effect of neighbouring conductors. Thus, Fig. 4 (not shown) two devices such as shown may be arranged in a tank in the manner of a conventional oilswitch with the nozzles facing away from one another, or, Fig. 5 (not shown), a single-break device may be included in one limb of a U-shaped arrangement having its limbs horizontal.
