Title: Capacitor having a cooperating dielectric
IPC: H01B3/30
Filed: 1970-04-27
Abstract: 1316144 Capacitors P R MALLORY & Co 27 April 1970 [28 April 1969] 20161/70 Addition to 1061628 Heading H1M A capacitor comprises at least two electrodes at least one of which is of film forming metal having an anodically formed dielectric oxide layer thereon, a further dielectric material between the electrodes and in contact with the dielectric oxide comprising a polymeric material selected from polycarbonates, polyphenylene sulphide, the product of curing a polysiloxane of formula where R 1 , R 2 , R 3 , R 4  are methyl or phenyl groups with a phenyl/methyl ratio of 0À1 to 0À9 to 1 and the ratio of the R groups to Si being 1 to 3: 1 and m and n are integers, epoxy resins and polyimides. As shown electrodes 1, 2 have anodic oxide films 1a, 1b, 2a, 2b on both surfaces of each, which films may be porous, non-porous or both, and polymer layers 3, 4 and 5, the assembly being consolidated by heat and pressure. The electrode layers may be smoothed and cleaned sheet, foil or flattened portions of wire. In a continuous process metal strip is anodized and coated with polymer by spraying, dip- or roller-coating, cut into portions, stacked with alternate ones in register and at right angles to adjacent cut strips. This "cross-stacked" may  be carried out in a jig with pegs and the completed stack compressed using an electrically or  fluid-heat die, or RF heating may be employed. In this arrangement electrodes of opposite  polarity extend to adjacent side surfaces and  contact to these is made, after trimming off excess polymer, preferably by flame-spraying metal,  (Fig. 6 not shown). Alternatively stapling, riveting or screwing may be used. Rolled capacitors may alternatively be manufactured (Fig. 7 not shown). Many examples of suitable polymers are given.

Patent GB-921605-A (GB)
Title: Improvements in and relating to superconductive circuits
IPC: H03K3/38
Filed: 1959-06-12
Abstract: 921,605. Superconductor circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 12, 1959 [June 13, 1958], No. 20273/59. Class 40 (9). [Also in Group XXXVI] A resistive copper wire 10 and a strip film 8 of superconductive material such as lead are connected in parallel to a battery 16 to form a relaxation oscillator or a one-shot multivibrator. The lead film 8 is deposited on an electrical insulating but heat conducting backing 2. Leads 12, 14, 18, 20 and terminal strips 4, 6 are always superconducting while the device is immersed in liquid helium. When film 8 is resistive, it has a resistance of about 100 times the resistance of the copper wire 10. When switch 26 is closed, the current grows in superconducting film 8 until it reaches a critical value at which the film is driven resistive by the magnetic field of the current. The film 8 rises in temperature and the current switches to wire 10 with a short delay due to inductance. When film 8 cools, it becomes superconductive, the current again rises and the process is repeated. If the current from 16 is restricted to a range of values insufficient to drive the film 8 resistive, current will normally flow in the film 8 but can be driven for a short time to wire 10 by a control pulse in a second film 28, Fig. 2, running parallel to 8. The pulse produces a magnetic field to drive film 8 resistive. The temperature of film 8 rises and the current switches to wire 10 but returns to film 8 when the film cools.

Patent GB-842690-A (GB)
Title: An improved process and apparatus for carrying out mass polymerisation
IPC: C08F2/00
Filed: 1958-06-25
Abstract: In a process of making polymers in the form of free-flowing powders by bulk polymerizing a monomer in which the polymer is insoluble, in the presence of a polymerization catalyst whilst subjecting the polymerizable mass to a pulverizing action, the remaining monomer or polymer formed are separately and successively withdrawn from the polymerization zone. Polymerization is generally terminated before complete conversion.  The polymerization is preferably effected in a horizontally rotatable autoclave containing loose metal balls or rods.  The monomer may be vinyl or vinylidene chloride and the catalyst benzoyl peroxide.ALSO:<PICT:0842690/III/1> The horizontal rotatable autoclave described in the parent Specification is modified by providing an evacuation member by means of which gases or solids and/or liquids may be removed therefrom separately and successively. In the Fig. 1 is the rotatable autoclave containing loose metal balls or rods, and flexible tube 13 the evacuation member which can be moved into the position shown by the broken lines.  In the first mentioned position the tube is arranged for the removal of solids, in the other position for the removal of gases or monomers.  The removal is effected by means of a suction device connected to 13 and the gases or monomers withdrawn recovered by passing them through a condensing system, whilst the solids are recovered and separated by means of a cyclone separator.

According to the direction of rotation of the brake drum 44, the shoes and actuator mechanism are carried round slightly and the deflection of the shaft 92 is permitted by the clearance in the bearing 96 and a flexible joint 104, 106, where the shaft passes through the cover-plate 48. The shoes are guided laterally by means of arms 52, 54, 56, 58 extending radially at each side of the webs from the spider plate 26. A modified construction is described in which the brake has a single combined cover and anchor plate.

Title: Improvements in and relating to the adjustment of cigarettes, particularly those of circular cross-section
IPC: B65B19/06
Filed: 1931-07-20
Abstract: 368,646. Arranging cigarettes for packeting. UNIVERSELLE CIGARETTENMASCHINEN-FABRIK J. C. MULLER & CO., 48, Zwickauerstrasse, Dresden, Germany. July 20, 1931, No. 20763. Convention date, June 11. [Class 94 (i).] . Cigarettes of circular cross section are arranged in the correct position in respect of their printed matter by a device which operates to turn the cigarettes about their longitudinal axes, and, at the moment when they arrive in the correct position, the device is put out of action by a heat- and light-sensitive device. The cigarettes z are placed on supports 2 on a conveyer chain 1 and rest in a groove formed by two rollers 5 mounted to contact with a roller 4. A photo-electric cell 6 and illuminating device 7 is mounted on a pendulum 8 operated by a quick return crank 11 so as to accompany each cigarette over a part of its travel. In the event of a cigarette being incorrectly placed, upon arrival beneath the pendulum, an armature 17 having a roughened surface 17<1> contacts with the roller 4, and the system and cigarette is rotated as shown by the arrows in Fig. 5. As soon as the printed matter on the cigarette comes upwards into its proper position the action in the photoelectric cell is such as to generate a current in the circuit 13 and in an amplifier circuit 15 so that the armature 17 is drawn downwards by the electromagnet 16. The rollers 4, 5 thereupon stop rotating and the cigarette remains in its correct position. If the cigarette is in the correct position to begin with, the armature 17 is drawn downwards the whole time, and no rotation takes place.

Title: Improvements in the manufacture of metal tubing

Abstract: 712,574. Making metal tubes ; bending ; welding by pressure. BUNDY TUBING CO. Aug. 23, 1952, No. 21229/52. Classes 83 (2) and 83 (4) A metal tube is formed from a continuous strip of metal 2 by a tube mill 1, having a plurality of rollers, and the longitudinal joint is first tack welded and then heated and subjected to pressure to cause recrystallization growth which extends completely from one tack to another across an interface and thereby completely weld the joint. During its formation a non-oxidizing or reducing gas is introduced into the tube through a pipe 6. The tack welding is effected by rotary electrodes 8 supplied with alternating current and which engage the tube on opposite sides of the seam. The tube then passes into a housing 15 where it is subjected to electrical resistance heating by electrodes 17, 18, 19 supplied with current from a transformer 16<SP>1</SP>, and is fed through a pair of squeezing rolls 20 to effect the pressure welding. A non-oxidizing or reducing gas is admitted to the housing at 21. A water jacketed cooler 22, 23 is disposed adjacent the housing. The tube may be heated uniformly throughout its circumference or it may be heated and plastically deformed only in the vicinity of the joint in which case the edges of the tube may be scalloped or serrated to facilitate the pressure welding. Examples are given of the temperatures at which the recrystallization occurs.
