Title: Methods and apparatus for covering filaments
IPC: C03C25/10
Filed: 1974-06-28
Abstract: 1518082 Covering tapes POST OFFICE 20 June 1975 [28 June 1974] 28795/74 Heading B8G To produce a covered filament, a filament is supplied from a melt, at least one tape is applied to the filament to envelop the filament, the or each tape extending in the longitudinal direction of the filament, applying heat to at least one of the tapes, and closing the envelope in the longitudinal direction, the or each strip comprising a bonding strip of plastics material with a high melting point and a coating of low melting point plastics material forming a bonding material, the or each tape being applied to the filament with the coating in contact with the filament, and in the covered filament the or each tape is partially bonded so that it can be peeled from the filament. Fibre optic filament 1, Fig. 1, pulled from a melt, engages tape 3 in the grooved periphery of driven pulley 2, and is carried to the flat rim of driven roller 4 where tapes 3, 5, of plastics material engage. The filament is pulled by the tapes although at least part of the pull may be applied direct to the filament. Several filaments may be covered by the tapes, e.g. using a multi-grooved pulley. Alternatively, only tape 3 may be used, the tape being folded and sealed after leaving pulley 2. In Fig. 2 covered filament 7 is turned through 90 degrees between the roller pairs. To heat seal the tapes, Fig. 3, filament 15 and tape 17 engage on the flat rim of driven wheel 16, and further engage tape 21 on the grooved rim of freely rotatable annulus 18 heated by induction heater 22. Wheel 16 may be replaced by a second heated annulus. The tapes, of plastics material have a low melting point coating on one side. Wheel 24, spring-biased against driven wheel 23 which pulls the filament, seals the tapes. Tape tension is maintained by reel brakes 38, 44, driven rollers 39, 45, and vertically slidable pulleys 41, 47. Sensors 51, 52, respond to the pulley positions and adjust the tape feed. The tape heating may be varied so that the filament is partially bonded to the tapes, or filament bonding may be prevented by providing annulus 18 with a groove to bridge the filament. The tapes may be heated by a hot air jet, a flame-heated PTFE roller, or dielectric heating, or. by contacting electrodes or by ultrasonic means.

Title: Improvements in and apparatus for the recovery of nitrogen and oxygen
IPC: F25J5/00
Filed: 1937-10-22
Abstract: 501,305. Separating air by liquefaction. JOHNSON, C. W. (I. G. Farbenindustrie Akt.-Ges.) Oct. 22, 1937, No. 28886. [Class 8 (ii)] Air to be separated in a double-column rectifier E is passed through cold-accumulators A ... D in alternation with the separated nitrogen and oxygen, and the purity of these products is increased by withdrawing a mixture of nitrogen and oxygen from the middle of the upper column of the rectifier. Loss of cold is compensated by addition of highly compressed air supplied through a pipe b cooled by the withdrawn gas mixture, and expanded through a valve R. Additional cooling is obtained by withdrawing nitrogen from the first column, using it to cool the high pressure air in an exchanger G, and expanding it in an engine H before its passage through the accumulators D with the main body of nitrogen. The withdrawn mixture may be compressed to high pressure and used in place of the auxiliary air, or it may be used in auxiliary accumulators to cool the incoming air of relatively low pressure.

Title: Automatic telecommunication exchange
IPC: H04Q3/00
Filed: 1967-06-23
Abstract: 1,129,080. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 23 June, 1967 [28 June, 1966], No. 29107/67. Heading H4K. In an exchange system having a reed relay switching network through which paths are selected by means of a route simulation network, the latter's guide wires are busied by means of a distinctive potential when the corresponding links in the switching network are busy, this potential being removed in the event that an existing connection has to be rerouted. The cause of the rerouting may be: release of local junctor and selection of new path to outgoing junctor in the event of an outgoing call; release of outgoing junctor and selection of new path to local junctor in the event of a local call; call transfer. The removal of busy potential from the guide wires may be effected immediately a reroute is required or only after one unsuccessful attempt at selecting a new path has been made. In either case the existing path is not broken down until a new path has been set-up. The particular form of the simulating network and the method of applying metering pulses over the guide wires are more particularly described in Specification 1,128,427.

Title: Converter temperature control with flue gas and steam injection
IPC: C21C5/30
Filed: 1957-09-17
Abstract: <PICT:0846587/III/1> Exothermic heat evolved in a tubular catalytic reactor, is removed by circulating a cooling gas e.g. flue gas in a sinusoidal path through a series of zones surrounding the reactor tubes, and also admitting steam to the successive zones as exothermic reaction proceeds to the discharge end of the tubes.  Preferably steam is mixed with the cooling gas entering the first zone.  A reactor consists of a shell 1, Fig. 1., in which the reactor tubes containing catalyst are mounted.  Only two are shown at 3.  The space surrounding the tubes is divided into zones by baffles 4, 5, 6, 7, 8. When the catalyst is exhausted the reactant gases entering at 13 are cut off, and heated regenerating air is admitted through a valved pipe 10.  Cooling gas is admitted to the top zone through a pipe 17, and saturated steam through a pipe 19. As the exothermic combustion zone moves slowly downwards through the reactor tubes, thermocouples 25, 29, 33, 37 actuate in turn valves 22, 26, 30, 34, releasing steam admitted through a pipe 19 to spurging tubes 24, 28, 32, 36, in the zone requiring coolant. As temperature in the upper zones falls the steam supply is cut off.  Preferably saturated low pressure steam is used.  The catalyst is thus not impaired by over heating.

Title: Bonding of polytetrafluoroethylene to metals
Inventor: MITCHELL DAVID CONRAD
IPC: B32B15/08
Filed: 1951-12-17
Abstract: The surface of steel, nickel or other metal which does not soften unduly at 400 DEG  C. and preferably previously roughened, is coated with a layer of polytetrafluoroethylene by bringing a cleaned metal surface into contact with a coating of polytetrafluoroethylene which may be in powder or granular form and subjecting the two to pressure at a temperature of 320-400 DEG  C., e.g. by heating electrically or by the use of a hot bed on which the metal rests or by applying heat to the interface electrically or otherwise, e.g. by supersonic radiation.  The time required to effect the coating varies with the pressure, e.g. two hours at 5 lb. per square inch or two minutes at 2 tons per square inch and where it exceeds more than a few minutes the heating is carried out in an inert atmosphere.  Continuous coating may be effected by feeding a metal strip through a heater to a sprinkler device which supplies a layer of p.t.f.e. and then to a hot bed where pressure is applied by a cold roller and finally to a cooling chamber.  Specifications 657,080 and 657,085, [both in Group XXXIV], are referred to.
