Patent GB-1155903-A (GB)
Title: Apparatus for receiving communication signals
Inventor: PIERCE JOHN ROBINSON
IPC: H04B7/10
Filed: 1966-09-28
Abstract: 1,155,903. Communication system; aerials. WESTERN ELECTRIC CO. Inc. 28 Sept., 1966 [29 Sept., 1965], No. 43241/66. Headings H4A and H4L. The Specification describes means for receiving a radio communication signal subject to multiple reflections and possibly exhibiting a resultant standing wave system, wherein the electric field and magnetic field of the radio signal are separately detected to produce first and second signals and the two signals are squared and combined to produce a signal, proportional to the power of the radio signal and thus independent of the reflections, or the two signals are passed to a circuit which only passes the larger of the two signals for utilization. The antenna system may comprise a vertical element 12, Fig. 2, for receiving the vertically polarized electrical field component EZ of the radio signal, and two mutually perpendicular vertical loops 14 and 16 for receiving the perpendicular components HX, and HY of the magnetic field component of the radio signal. The antenna system may alternatively comprise, Fig. 3, two vertical mutually perpendicular half loops 23 and 24 mounted above a reflecting ground plate and feeding respective hybrid rings 26 and 27, the rings giving respective difference outputs representing HX and HY, with both rings giving sum outputs representing EZ. In the first case, to ensure a linear system the carrier at the transmitter is modulated by the square root of the voice signal, Fig. 1 (not shown). The HX, HY and EZ signals, after convertion to IF signals, Fig. 4, are detected in respective square law detectors 36, 41 and 32. The outputs are combined in amplifier 42, to produce the required power representative, reflection independent, voice signal. In the second case, using linear frequency modulation, the EZ, HX and HY signals are converted to IF signals and passed to respective balanced discriminators 72, 73 and 74. Diodes 76, 77, 78, 82, 83 and 84 are placed between the outputs of the discriminators and the output C/R network 90, 91, 92 and 95, such that all the diodes are cut off except that which passes the signal of greatest amplitude. This signal then passes to the output transformer 86, a centre tap on the primary winding thereof, providing an A.G.C. signal for the IF amplifiers.

Title: Transport System for Single Sheets of Photosensitive Material
IPC: G03B27/58
Filed: 1968-09-13
Abstract: 1,187,537. Electro-photographic and photographic apparatus. METEOR-SIEGEN APPARATEBAU PAUL SCHMECK G.m.b.H. Sept.13, 1968 [Sept.15, 1967], No.43686/68. Headings G2A and G2H. Single sheets 15 of photographic or xerographic copying material are transported by an endless conveyer belt 5 tensioned between drive 2 and reversal 1 rollers, an electrostatic charge sufficient to attract and retain in relative position the transported sheet to the belt being transmitted to the belt from a D. C. voltage source 8 by means of an electrode 7 extending transversely of the belt, and a load resistor 9 being connected between the D.C. voltage source and the electrode so that as the transfer resistance between the electrode and the closest point of earth potential falls and the current flow through the electrode increases, the voltage applied to the electrode falls. An earthed roller 3 urges a sheet to be transported on to the belt and is provided with a guiding bar 6. The provision of the load resistor minimises the risk of spark-overs during conditions of low transfer resistance, e.g. humid conditions.

In one embodiment, Figs. 2 and 6, weft is measured by rollers 3, 4 and gripper 7, 8 moves upwards during insertion by gripper shuttle 18, so that a new loop is being formed in tube 6, while the previous one is still being drawn out to be inserted. In an alternative embodiment, Figs. 15 and 19, weft is wound continuously on a drum 132 a 132' releasing yarn from the drum for insertion, which passes through guide 133 and a further guide 135 on a pivoted lever 136, which by way of yarn guiding pin 137 successively presents yarn to suction storage tube 138. Yarn is projected as a loop 140 into the shed by a wheel 134, as described in Specification 1208920; which loop straightens itself out and is caught on the opposite side by a brake 149 which opens for this purpose. In a further embodiment, Fig. 21, the yarn end is caught in a suction nozzle 223 on the opposite side before passing into a brake 224. Yarn grippers; suction storage tube, Fig. 10. A yarn gripper, in which the clamped jaws can be moved across the mouth of a yarn storage tube 119 is provided by having one jaw 107 operated by a toggle linkage on a pivotable lever 100, the other jaw consisting of a flexible strip 102 carried by lever 100, the toggle linkage being operated by a camactuated rod 113.

Weft as it is inserted or pulled back passes over a piezoelectric or triboelectric sensor 225. A suction nozzle 217 opposite sensor 225 pulls the yarn away from the sensor if it is slack, and an electric circuit (Fig. 22, not shown) is programmed to stop the loom when it does not receive signals from sensor 225 at the end of the picking motion of the shuttle, and after the drawing back means has operated. Framework Figs. 8, 9. Uprights 30 support a transverse metal guide plate 31 for the finished fabric, and respective supports 37 on the inside of each upright hold a metal sheet 38 which supports the shedding motion 39. Boxes 41, 41' on either side of the loom enclose gearing driving subsidiary shafts from the main shaft 44. Picking, guiding shuttles Fig. 8. Shuttles are picked by a picking wheel 63 and move in semi circular guides 64, 68 outside of the shed and are returned in a guide member 69 to the picking side of the shed.

Abstract: 1,077,629. Tuned transmission lines. AGA A.B. Oct. 26, 1966 [Nov. 23, 1964], No. 45245/65. Headng H1W. A tuner for the 20-400 MHz range comprises a capacitor and a number of electrically parallel conductors rotatable about a common axis towards and away from a ground plane, the arrangement being such that the conductors approach each other as they are rotated away from the ground plane. The two conductors 3, 4 shown in Fig. 7, are of U-shape and are rotatable about an axis 6 passing through the limbs of the U's. The position of the conductors determines the characteristic impedance and hence the resonant frequency of the arrangement, the impedance being at a maximum when the conductors are closest together and farthest away from the ground plane (position indicated by broken, line). Although a simple flat ground-plane may be used, the one illustrated consists of two troughs respectively formed by members 18, 19 and 20, 21. Trimming may be accomplished by bending the sides of the troughs, as shown. The electrical length of the arrangement may be increased by capacitative loading. two systems may be connected in tandem, the second system being rendered inoperative by a short-circuiting switch at the connecting point. The Specification describes a modification using three U- shaped conductors.
