Abstract: 794,972. Coating non-metals with metal. METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. Sept. 28, 1954 [Sept. 28, 1953], No. 26652/53. Class 82(2) [Also in Group XXXV] A continuous electrically insulated backing strip is coated with an electrically conductive coating (e.g. metal) by simultaneously applying the coating and a continuous, narrow control strip, from a common source, and using the variation in resistance of the control strip to control the rate of metal deposition from the common source and hence the thickness of the coating. The process is particularly adapted to the formation of printed circuits where a negative of the desired circuit is first printed on, the metal &c. is then coated on and a solvent removes the printing ink and its superposed layer, the strip being then dried. The coating may be effected by vapour deposition, spraying or deposited from a liquid. An emitter 8 in a vacuum vessel 10 deposits on the strip 1 fed over an idler 3 by a torque roll 4. Baffles 9 preferably water cooled and a mask 12 form the control strip which is contacted by two rollers 5, the portion between them forming one arm of a bridge circuit that is arranged to control the strip speed or rate of emission of the emitter 8 to give a constant thickness of deposition .The thus coated strip 16 is then passed through a solvent bath 19, over brushes 20, into a solvent flushing compartment 21, over drying rollers 22 and to a take-up spool 24. Coatings of copper or a nickel/ Chromium alloy are disclosed. Specification 794,971 [Group XXXVI] is referred to.

Title: Improvements in or relating to magnetic memory elements
Inventor: FRANKLIN ERNEST
Filed: 1958-08-22
Abstract: 875,192. Magnetic storage devices. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Aug. 13, 1959 [Aug. 22, 1958], No. 27016/58. Class 38 (2). [Also in Group XXXIX] A magnetic memory element comprises a thin nickel iron film 2 (Fig. 5) deposited on a drive conductor 1 and a transverse output winding 3, the film being suitable for switching by domain rotation and having an easy direction of magnetization. High reversal speed is obtained by using a field in the easy direction together with a field at right angles thereto. This may be obtained by applying the latter as an external field He along the axis of the drive conductor when the easy direction of magnetization is circumferential or by using a second transverse winding carrying a pulsed or steady current or by making the film with an easy direction of magnetization at a predetermined angle to a tangential line normal to a plane containing the conductor axis. The transverse conductor can be a strip of width comparable with the length of the film and may not surround the film completely (Figs. 6 and 7, not shown). A matrix store may be formed by a number of wires 1, 1<SP>1</SP> (Fig. 4) each carrying a number of films 2, 21 and windings 3, 31 and each forming a " word " wire. The transverse field component for fast switching is provided by coil 4. A separate inhibiting winding may be provided, the inhibiting field neutralizing field He and so increasing switching time that with a suitable drive width pulse there is little disturbance in the inhibited cores. The film may be deposited as described in Specification 859,725.

Title: Improvements in or relating to apparatus for the manufacture of artificial filaments, threads and the like
IPC: D01D4/02
Filed: 1929-09-05
Abstract: 339,670. British Celanese, Ltd., Tidmus, A. H., Reeson, F. A., and Riley, R. H. J. Sept. 5, 1929. Apparatus for making filaments. - In apparatus for making filaments, ribbons, straw, and the like, particularly by the dry or evaporative process, two spinning jets are arranged in series and in proximity to each other on a single supply pipe in such a way that the second jet may be removed or replaced without interfering with the first jet. When the second jet is removed, spinning proceeds through the first jet, which also serves as a pressure retaining member. The first jet is formed with one or more holes of sufficient total area to enable the second jet to receive an adequate supply of spinning solution. It may also serve as an additional filtering means for the spinning solution if it is provided with holes of the same or smaller size than the orifices in the second jet. By making the number, size, and shape of the orifices of the first jet different from those of the second jet, or by replacing the second jet by another, the character of the product spun as regards the number or denier of the extruded filaments may readily be changed. In Fig. 1, a pipe 11 for supplying solution to the jets is provided with a nut 12 to which a nut 14 is screwed to hold the first jet 15 against the under-side of nut 12. A split nut 17, 18, which embraces the nuts 12 and 14, is screw-cut outside with a left-hand thread which receives a nut 24. A bearing surface 25 on the nut 24 clamps nut 17, 18 about the nuts 12 and 14 and holds a second jet 26 against the under face of the nut 14. The second jet 26 can thus be readily removed and replaced without interference with the connection of the first jet 15. In a modification, the nut 14 has an exterior left-hand screwed thread which receives the nut 24, and the use of the split nut 17, 18 is dispensed with. In the construction shown in Fig. 5, the second jet 26 is secured in a cylinder 35, adapted to slide over the nut 14. The cylinder 35 is locked in place by means of spring-pressed balls 41, which fit over the top edge of the nut 14, or by means of set screws 44, which are coned at their ends so as to fit over the top edge of the nut 14.

Title: Glass bottle parison machine
IPC: C03B9/16
Filed: 1962-07-13
Abstract: <PICT:1010657/C1/1> An apparatus for making glass bottle parisons comprises a parison mould having an open upper end and a bottom ring neck orifice, a movable plunger capable of substantially closing the neck orifice, means for withdrawing air from the mould through the neck orifice and timing means for controlling the upward movement of the plunger into the orifice closing position concurrently with the approach of a charge of glass into the bottom end of the mould.  A vertical parison mould comprises two plates 18 with complementary cavities 20 and a baffle seat 22.  A ring neck mould 26 seats a thimble 28 mounted below which is a casting 30 housing a plunger 32. The plunger 32 is mounted on a hollow piston-rod 8 of a piston 34 within a cylinder 36 and can be raised against the action of a spring 38 by compressed air supplied via a line 58. A tube 52 is mounted on the bottom of the piston 34.  Another piston, not shown, actuates the thimble 28. A compressed air valve 62 comprises a valve head 61 mounted on a stem 66 having axially parallel surface flutes 68 and a reduced portion 74, the whole sliding in a bore 70 in a casting 72. The valve head 61 is normally held by a spring 64 in the position shown, in which position any compressed air in passageways 78, 80 evacuates down the flutes 68 and out of a ring groove 82.  When actuated by a cam head 84, the head 61 is raised allowing air to flow from a chamber 60 into the passageways 78, 80 and an annular shoulder 86 seats against the wall of the casting and prevents escape of air down the flutes 68.  The cam head 84 is raised into locking engagement with a latch 102 by an "up" button 90 on the arc of a timing drum 88 and lowered by the release of the latch 102 by a "down" button 92.  A needle valve 114 controls the rate at which compressed air is supplied to the piston 34.  A similarly operated valve 172 supplies air to a line 184.  A suction control valve 118 comprises a housing 120, a piston 124 contacted by a spool 128 with a collar 132 against which an expansion spring acts urging the spool 128 and piston 124 downwards.  Between two brass bushings 138, 140 is an annular chamber 142 with spacers 144, 146, 148 each consisting of two rims 149, 150 spaced by rungs 152, the spacers 144, 146, 148 being separated by polytetrafluoroethylene seals 160.  A chamber 162, within the spool 128 has two rings of ports 164, 166.  In use, as a gob of glass is about to drop from a deflector 10, actuation of the compressed air valve 62 by the timing drum 88 causes the plunger 32 to rise at a predetermined rate while simultaneous operation of the valve 118 connects the plunger 32 to a suction source 158 and sucks air out of the parison mould cavity 20.  Valve 62 then closes, venting the compressed air in lines 58, 116 which allows the plunger 32 and the spool 128 to return to their lower positions permitting counterblowing of the parison, via a line 184 and the valve 118, on the operation of the second compressed air valve 172 by the timing drum 82.  Specification 1,008,038 is referred to.
