Abstract: 1356666 Finishing extruded pipes GENERAL TIRE & RUBBER CO 26 Aug 1971 [28 Aug 1970] 40176/71 Heading B5A [Also in Division H5] Irregularities in the inner surface of an extruded tube 2, Fig. 1, e.g. which have been caused during passage around an internal sizing mandrel 4, are smoothed by the surface tension of the material of the inner surface of the tube during heating with relative movement between the tube and an inductively heated radiant heating source 12 of the same shape as the tube, e.g. circular or oval, and located in spaced relationship within the tube. The source 12 is heated by a concentric electric induction coil surrounding, and of larger internal diameter than, the external diameter of the tube. The tube 2 may be reinforced by a braid, covering, or a spiral reinforcement embedded within its wall, but in the preferred embodiment comprises an extruded unplasticized P.V.C. core extruded, within a plasticized P.V.C. covering, from a die outlet which rotates. The sizing unit 4 comprises a hollow member 5 around which the tube 2 is delivered by soft endless belts 6, the tube 2 during passage around the member 5 contacting and moving therewith a plurality of polytetrafluoroethylene endless tapes 10 which circulate along the surface of the member 5 and, via slots in its wall through the hollow interior thereof. The tube 2 discharged from the unit 4 is cooled sufriciently to be selfsupporting, prior to passage around the radiant heating source 12, e.g. of iron or its alloys, or carbon, which effects the smoothing of irregularities comprising longitudinally extending ridges formed at the junction of adjacent tapes 10. The heating source 12 is attached to, and thermally insulated from, the sizing unit 4 by three ceramic cylinders 14, or fins, and is heated by the surrounding induction coil 16 comprising windings of copper tubing connected to a high frequency generator producing, e.g. 450 K.H., preferentially inducing the heating current at the surface of the source 12. In the Fig. 3 embodiment, the source 112 is heated by an induction coil 116 encased in epoxy resin, and is attached by similar insulators 114 between a pair of, or to the end of, an internal tube support 120 which is in turn attached by a cable 132 to the end of an internal tube sizing mandrel. The support 120 comprises an aluminium cylinder provided with rings 122 of polytetrafluoroethylene, or silicone or urethane rubber, which support the tube 2 internally, the support 120 and the plastics tube 122 being supported externally by several pairs of rollers, 124, 126 which engage the tube 102 at V-shaped foam rubber grooves and are adjustably spaceable apart. The source may alternatively be mounted to the end of a rod of a length at least equal to that of the tube along which the source and induction unit are moved. An example is given of the conditions at which the interior of a polyvinyl chloride tube is smoothed.

Title: Ring laser having means for preventing mode locking

Filed: 1970-08-26
Abstract: 1,269,905. Lasers. BENDIX CORP. 26 Aug., 1970 [5 Sept., 1969], No. 41087/70. Heading H1C. A circular polarizer 27, Fig. 1, is used in a ring laser to prevent mode looking. A gas laser tube 9 gives two output beams which are oppositely directed around a ring path by mirrors 19, 21, 23, 25, the latter being partially transmissive to allow the counter-rotating beams to be combined by mirrors 29, 31, 33 at detector 35. The unpolarized light emitted by the gas tube 9 is circularly polarized by the device 27 which is a Fresnel prism. Because of the polarization sense reversal at each mirror, paths 3 and 7 have polarized light of one sense travelling in both directions, while paths 2 and 5 have light of the other sense travelling in both directions. Suppose the counter-rotating beams in path 7 are both right circularly polarized; back-scattered light from one beam will be left circularly polarized and will not therefore interact with the other beam. Also, the back-scattered light will be refracted out of the resonator by the Fresnel prism. This prevents the two counterrotating beams mode locking, so that when used as a gyroscope very low rotation rates may be detected. In Fig. 2 the ring shown is three-sided, and the circular polarizer 53 is sense reversing so that the two counter-rotating beams have the same sense as one another at any given point. The polarizer 53 comprises two quarter-wave plates 55, 57, with their fast axes aligned, and two Brewster plates 59, 61. Right circularly polarized light incident from mirror 39 is blocked, while left circularly polarized light is transmitted with its sense reversed. Similarly right circularly polarized light incident from mirror 41 is transmitted with its sense reversed while the left circularly polarized light is blocked. If the quarter-wave plates have their fast axes perpendicular, the polarizer is not sense reversing and may be used in even-sided rings such as that of Fig. 1.

Title: Improvements in transistor mixer circuits

Abstract: 916,034. Transistor frequency changing circuits. PYE Ltd. Dec. 30, 1959 [Dec. 30, 1958], No. 42052/58. Class 40 (6). In a transistor mixer circuit, in which the input signal and the local oscillator signal are both applied in series to the emitter-base path of the transistor X1, coupling between the signal input circuit and the local oscillator circuit is reduced by the application of one of the signals through a tapped transformer winding S2A having one end connected either to the base or emitter of the transistor and its other end connected to an added impedance, whose value is so related to the base-emitter impedance and to the position of the tap on the transformer and the other input signal being so applied between the centre tap and the end of the added impedance remote from the transformer, that neither the input signal current nor the local oscillator current in the base-emitter circuit can induce any substantial voltage in the local oscillator circuit or the input signal circuit respectively. Since the part of a transistor included between the base and emitter terminals is very nearly equivalent to a resistor in parallel with a capacitor, the added impedance takes the form of a resistor R3 in parallel with a capacitor C3 connected to one end of the coil S2A, coupled to the local oscillator, and to the transistor base through the D.C. blocking capacitor C2. The ratio of the impedances of the two resistorcapacitor combinations is made equal to the ratio of the potential differences between the top of the winding of coil S2A and each one of the corresponding terminals of this winding. Thus the difference between the potentials of the tap and the transistor base is independent of any change in potential difference between the terminals of the winding S2A energized by the local oscillator, and so the input signal winding S1 will not receive any energy from the local oscillator. Conversely the input signal coil S1 cannot provide the oscillator circuit with any energy because the signal current flows in opposite directions in the two sections of the coupling coil S2A on either side of the tap and the consequent magnetic fluxes produced cancel out. The local oscillations may be fed to winding S2 from an independent local oscillation generator, and the resistor R3 and capacitor C3 may be replaced by a transistor presenting the same capacity and the same conductance between the base and emitter terminals.
