Abstract: 832,868. Winding strands. GEOFFROY-DELORE S.A. Jan. 14, 1958 [Jan. 17, 1957], No. 1299/58. Class 120(2) [Also in Group XXV] Strands to be twisted together in two steps are first wound on to a rotatable drum, from which they are then drawn 'off and wound on a reel. The reel 10 is driven at a speed controlled by a tension roller journalled on a pivoted lever 13 which, upon slackening of the assembly 2, rotates against the action of a spring 14 to increase the tension of a driving belt 12. A reversible haul-pulley device comprises a sheave 38', Fig. 5, journalled on the end of a rocking arm 57 controlled by the tension of the cable and pivoted about the axis of a sheave 38. The stands are passed over pulleys 32-35, are wrapped around sheaves 38, 38<SP>1</SP> and pass to a traverse mechanism to be wound on the drum 9. The sheave 38 is driven from a gear 40 through a reverse gear and transmits drive to a lay-shaft 90. The drum 9 is driven from the lay-shaft 90 through a gear train containing a friction clutch 45 and free wheel 46, Fig. 7. In the first step, the sheave 38 is rotated in a clockwise direction in Fig. 5 and drive is transmitted to the drum 9, the engagement pressure of the clutch 45 being regulated by the rocking of the lever arm 57 to maintain constant tension in the assembly being wound. In the second step, the sheave 38 is driven in the opposite sense and the drum 9 is rotated by the unwinding assembly. A second free wheel 47, Fig. 7, connects the clutch 45 with a boss of the stationary frame 7 so that it retards the free rotation of the drum 9, engagement of the clutch being still regulated by the lever arm 57. The traverse mechanism comprising a pulley 48 and roll 49 is reciprocated on two guide bars 50 by the engagement of the roll 49 in a helical groove 51 on a cylindrical casing 53 which is driven from the sheave 38. A stop motion comprises an apertured guide 69 and plate 70 of conductive material supported on an insulating member 68 which is slidably mounted on a conducting bar 65 and normally held in position by a spring 72.

Abstract: 1,255,951. Transistor oscillator circuits. E.M.I. Ltd. 24 Dec., 1968 [10 Jan., 1968], No. 1401/68. Heading H3T. [Also in Divisions H1 and H2] A microwave oscillator comprises a transistor oscillator coupled to a resonator, feeding a step recovery diode which gives an output harmonic frequency to which a filter is tuned. The circuit is shown in Fig. 3, coil 2 representing the resonator 2 of Fig. 1. Supplies to emitter and base are connected via chokes 11, 14, the frequency of oscillation being determined by the various capacitances in circuit especially the controlled varactor capacitance 13. This oscillation is sensed by conductor 16, connected to container wall 3 via trimmer capacitor 17, which transmits the signal via central conductor 18 of a coaxial line to a step recovery diode 25. An output from this diode has a high harmonic content to which required frequency a waveguide filter 23 is tuned. The waveguide is a quarter wavelength, at the harmonic frequency, from the diode such that the wave oscillates in the quarter wavelength line, adjustment of the Q of this line being achieved by varying the position of the post 24 formed by the end of conductor 18. The cavity filter comprises a waveguide 23 with a short-circuited end 31 and divided into three separate filter sections by posts 32, 33, 34, 35, the sections being individually tuned by screws 36, 37, 38. The base of container 3 has an annular cut away portion 30 which forms with member 21 a radial transmission line having a susceptance tuning out the inductance due to the diode.  The resonator may be filled with polyurethane foam to give mechanical rigidity to the leads and components within the resonator, vibrations of which would affect its performance.
