Patent GB-1386066-A (GB)
Title: Electric cables
IPC: B29C48/06
Filed: 1971-09-13
Abstract: 1386066 Extrusion coating of twin conductors BRITISH INSULATED CALLENDER'S CABLES Ltd 13 Sept 1972 13828/74 Divided out of 1371211 Heading B5A A method of making electric cable comprises passing two or more parallel coplanar conductors 11, 19 including at least one with insulation 12, through the core tube of an extrusion machine which applies a continuous overall covering 14 around the conductors, and continuously treating the covering by passing it through a chamber sealed to the outlet of the extrusion machine and containing a fluid medium under super-atmospheric pressure. Another fluid injected at a lower pressure into the core tube maintains a pressure differential across the covering 14 at the extrusion orifice sufficient to cause the covering to collapse firmly on to the conductors 11, 19 but insufficient to force the covering back along the core tube. The resulting covering 14 has approximately uniform radial thickness around most of its periphery, having arcuate end parts 16 united by re-entrant parts 17 and bounding a single bore 13. Where the covering is to be heat-treated the fluid medium in the pressure chamber may be steam or other suitable curing fluid; where it is to be cooled the medium may be water. The fluid injected into the core tube is preferably an inert gas, e.g. nitrogen.  Preferably the pressure differential is automatically controlled by altering the rate of injection of fluid into the core tube. The thickness of the covering 14 responds to the throughput speed, so allowing a wider tolerance on the dimensions of the extrusion dies. It is stated that no bonding occurs between the primary insulation 12 and the covering 14, even without the use of French chalk or other preventive material, and even when the primary insulation and the covering are of the same material, e.g. PVC. Appropriate legend can be indented or embossed on the covering, preferably on an arcuate surface 16. Specification 1,371,211 is referred to. Reference has been directed by the Comptroller to Specification 1,201,528.

Title: Gas and/or vapour discharge lamp
IPC: H01J61/28
Filed: 1973-03-22
Abstract: 1416482 Discharge lamps PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 22 March 1973 [25 March 1972] 13854/73 Heading H1D [Also in Divisions G3 and H2] A discharge lamp has a reservoir 6 of ions which are present in the discharge and means are provided for reversing the polarity of a direct potential on the reservoir relative to the discharge so as to control the direction of flow of the ions between the reservoir and the discharge. In the arrangement shown in Fig. 1 a high current through the main discharge path of the lamp increases the voltage drop across resistor 5 resulting in the breakdown of zener diode 9 and the imposition of a negative potential on reservoir 6 relative to electrode 16 resulting in the withdrawal of ions from the discharge. Conversely a low current will close the contacts 14 of relay 4 resulting in a positive potential on reservoir 6 during the half cycles when diode 15 conducts which will have the effect of adding ions to the discharge. In the case of a sodium lamp the reservoir can have a wall of #-aluminium oxide and can contain sodium fluoride or pure sodium. In another embodiment, Fig. 2 (not shown) the auxiliary potential applied to the reservoir is from a separate D.C. supply via a two-way switch for reversing the polarity in this case for varying the colour of the lamp which contains caesium and potassium in addition to sodium and neon or argon.

Title: Method of and means for determining the thickness of materials
IPC: G01B7/06
Filed: 1931-05-15
Abstract: 379,309. Coating webs. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. May 15, 1931, No. 14453. Convention date, Oct. 3, 1930. [Class 140.] The thickness of insulating materials, such as rubber and linoleum, built up in a number of layers is determined by the variations in electrical capacity of a condenser constructed so that the electric field runs entirely, or in part, in the longitudinal direction of the layers. Apparatus for measuring the thickness of running layers forming the dielectric comprises two such condensers connected in an alternating- current bridge together with a measuring instrument for indicating the differences in thickness of two dielectric layers. Instead of the bridge connection, a cross-coil dynamometer, or a frequency responsive instrument may be employed. A further condenser of ordinary construction is provided for determining the total thickness, of both layers. In the manufacture of rubber-faced cord strips, relays are connected with the measuring circuit for controlling motors to vary the distance between the rollers of a calender machine. The shape and distance apart of the condenser electrodes may be adjusted to suit particular thicknesses of dielectric, the field preferably penetrating to a depth slightly greater than the thickness. Fig. 3 shows rubber-coated strip material 10 running across condensers 13, 16 which determine the rubber thickness on either side of the strip. The total rubber thickness is determined by running the strip through a condenser 17, 18. Capacity bridges 20, 27 indicate departures from normal thick. nesses by means of amplifiers 24, 32, rectifiers 25, 34 and instruments 26, 35. Relays 45, 46 operate contacts 47 .. 54 to close the circuit of a local source 55 energizing relays 57 .. 60 to operate main switches 61 .. 68 in the armature circuits of motors 70, 71 for adjusting the nip of the calender rollers.
