IPC: H01B13/10
Filed: 1968-08-29
Abstract: 1,202,455. Seaming non-metallic sheet material. FUJIKURA CABLE WORKS Ltd. 29 Aug., 1968, No. 41310/68. Heading B5K. [Also in Division H1] A plastics insulation B is applied to an electrical wire A, e.g. to form a core for a coaxial cable, Fig. 1, by continuously extruding a plastics tape B, longitudinally advancing the wire A, the tape B and a forming tape D in superimposed relation forming, the tapes B, D around the wire A with the tape D on the outside of the tape B, heating the tape B so that it surrounds the wire and peeling off the tape D from the tape B. The tape B, e.g. of polyethylene or polystyrene, is extruded from an extruder 1 to pass between moulding rolls 2 to form thin margins a and protrusions a 1 , a 2  on one face thereof. The tape B is trimmed by a cutter 3 and passes between rolls 4, over dancer rolls 5, 5<SP>1</SP> and a guide roll 6 to a heated forming device 7. The wire A passes from a supply 8 over guide rolls 9, 9<SP>1</SP> to the device 7. The tape D, e.g. transparent cellulosic film, paper, metallized paper or a combination of transparent cellulosic film and paper, is fed from a supply 10 and over guide rolls 11, 12 to the device 7. If the tape D is made of paper, silicone oil is applied by a unit 13 to one surface thereof to prevent adhesion to the tape B. In the device 7, the tapes B, D are wrapped around the wire A and heated to 60-70‹ C. The inner surface of the device 7 is coated with polytetrafluoroethylene. The outer diameter is adjusted by a die 16 and the longitudinal edges of the tape B are butt welded by hot air from a unit 15 blown into a slotted guide 14. The insulated wire is cooled at 17 and passes through a unit 18 to measure the electrostatic capacity thereof so that the speed of an extractor 19 and the temperature within the guide 14 may be adjusted, if necessary. The insulated wire is taken-up at 20. In a modification (not shown), the unit 15 and the guide 14 are omitted and the edges of the tape B are butt welded in the device 7.

The processor 9 is associated with a modulo N counter 8 which counts at the pulse rate of the main pulse train and whose state defines at any one instant the position of a current bit within a frame, and the unit 4 includes an auxiliary modulo N counter 12 connected to receive counting signals from the main unit at a rate which is a sub multiple n/N of the main pulse rate in such a manner that a part of the auxiliary modulo N counter counts at the same rate as the corresponding part of the main modulo N counter, and the specification explains how this enables the separate processing to be effected. The main unit may also be provided with an output 1 associated with a main processor 7 with counter 6 and an auxiliary processor 11 with counter 10. The auxiliary processor may process only n1 bits, the remaining (n-nl) bits being processed in one or more further auxiliary processors, and embodiments having a plurality of auxiliary units are described with reference to Figs. 2 and 3 (not shown).

In a reheating furnace for metal billets, the work is fed through successive zones by separate walking beam conveyers, so that the time for which the billets remain in the different temperature zones can be regulated. In a furnace having a preheating zone 1 and a soaking zone 2, billets are fed through the zones by separate, independently driven walking-beam conveyers 3, 4. The conveyers 3, 4 are synchronised, and the leading conveyer 3 can be stopped independently while the soaking zone 2 is emptied by conveyer 4 and discharge conveyer 7. In a modification, Fig. 2 (not shown), the billets are transferred from the loading conveyer to the soaking zone conveyer down a shoot. A shoot and end discharge opening may follow the soaking zone conveyer.

Abstract: 975,887. Controlling distribution of liquids. SANDALL PRECISION CO. Ltd. Oct 24,1963, No. 42075/63. Addition to 924,896. Heading G3H. The detection of an interface between two liquids in a pipe 1 is effected by continuously pumping liquid from a tank 10 and returning it to the pipe 1, so that a float-operated valve 5 is maintained open to enable liquid extracted from the pipe 1 by a probe 2 to flow therethrough to a buffer tank 17 by a line 8. The tank 17 has a sloping bottom surface 18 and side baffles 20 forming compartments 17a, 17b which latter has upper and lower connections 24, 21 to the tank 10, the connection conveying sediment and water; compartment 17b also has an intermediate connection 26 whereby a sample is directed by a pump 27 to bridge-connected or parallel-flow circuits 36a, 36b and 37a, 37b via a pressure regulating valve 28, a check valve 31 and a heat exchanger 33. The circuit parts 36, 37 are formed by small-bore tubing and constitute restrictions, the parts 36b and 37b co-operating with telescopic tubes 38, 42 to enable the respective restrictions to be adjusted The parts 37a, 37b are joined by delay means 41 comprising an annular chamber whilst a differential-pressure gauge 40 is connected across the junctions between parts 36a, 36b, and part 37a and the delay means. The tubes 38, 42 open into a tank 44 with a connection 45 to the tank 10. The heat exchanger 33 parallel-flow circuits 36a, 36b and 37a, 37b, tubes 38,42 and delay means 41 are disposed in jacket 34 filled with liquid maintained at a constant temperature which liquid flows around the outside and inside of the heat exchanger 33. The sample liquid flows from circuits by way of a header tank 35. The delay means 41 provide for a greater viscosity gradient in parts 37a, 37b than in the other parallel limb 36a, 36b so that an interface at probe 2 is indicated by displacement of the gauge 40 from its normal zero reading. The gauge may control valves distributing the various liquids as well as the remote or audible indications of an interface.

Abstract: 1,244,862. Moisture measurements. HEAD WRIGHTSON & CO. Ltd. Sept. 9, 1969 [Sept.9, 1968], No.42730/68. Heading G1N. The moisture content of particulate material is determined by supplying the material to a conveyor belt 1, profiling the material, e.g. by a plough 2 or a hopper gate (7), Fig. 5 (not shown), and then determining the resistance of the material between two electrodes or sets of electrodes 4, 5, Figs. 1 and 2 (not shown) which are arranged to penetrate the material. The electrodes are constituted by sets of rods 5, offset relative to each other. The resistance may be determined by measuring the current or RMS current across the electrodes when a constant D.C. or a constant A.C. voltage respectively is applied. Effect of the varying conductivity of the belt may be eliminated by integrating the current signal over the time for one cycle of the belt. Two integrators controlled by a switching circuit may be used so that one integrator stores the current value while the other gives its output and vice-versa, the switching device being actuated at the end of each belt cycle. A temperature-compensating signal may be provided.

As described line 1, DMT1, Fig. 1, of a set of n test lines DMT1, ..., DMTn, includes four test stations PT1, ..., PT4, through which diodes under test for their capacitance, charge storage, forward voltage drop under constant current, and reverse current for constant reverse voltage, are transported. When the conveyer CE of one of the n test lines DMT1, ..., DMTn is stationary, i.e. is ready for testing, a signal PRET1, ..., n is sent to a control circuit MA which communicates with the controlling digital processing unit CAL over a link TCDM and interface circuitry INT. When test apparatus CM becomes available, CAL chooses a test line which is ready and controls switches AM, AS to select that line, e.g. DMT1. Assuming that line 1 has been selected, the four tests are then carried out successively under the control of the unit CAL using a programme Fig. 7 (not shown) which takes account of any previous tests, one of which will indicate the polarity of the diode. Test results RST1 are fed back via a link RM and the unit CAL then issues sorting commands CMT relating to the diode in the fourth test station which has undergone all the tests. According to all the results, commands are sent via switch AS to sorting control means CAS, thereby operating the means to direct the diode into the selected bin. At the completion of sorting, a signal MM1 is sent to initiate the conveyer drive, and the unit CAL searches for the next ready test line.
