Abstract: 1,095,434. Cables. FUJIKURA CABLE WORKS Ltd. June 1, 1965 [June 26, 1964 (2) ; July 9, 1964; Dec. 1, 1964], No. 23321/65. Heading H1A. To diminish cross-talk, alternately opposite twists are applied to communication cable strands 11a-11d in a twisting machine S comprising two twisting heads B and B2 capable of rotating in unison in either direction, the machine S being situated between two fixed heads A1 and A2 through which the wires pass on entering and leaving the machine. In the simplest case, when wires which have been twisted between A1 and B1 by rotation of the machine reach the zone between B2 and A2, reversal of the rotation imparts a reversed twist to the wires between A1 and B1 whereas an additional twist in the same direction is imparted to the wires between B2 and A2. Reversal of rotation without untwisting of the wires between B2 and A2 may be carried out whenever the wires advance a distance L, the average of the distance between A1 and A2 and between B1 and B2, devided by an odd number. The required length of wire between the twisting heads may be supported on two pulley heads or an endless belt. A number of quads, each having imparted thereto alternate twists on machines as above may be stranded together with alternate twists in a further machine as illustrated in Figs. 4 and 5 (not shown). Preferably, the individual quads have been treated at different rotational speeds with different reversal periods, or have different phases. The wires forming the quads may be bound together by passage through a bath of adhesive and the groups of quads may be bound by bonding strip or thread.

Abstract: 978,123. Changing displays. ELLIOTT BROS. (LONDON) Ltd. June 29, 1962 [June 29, 1961], No. 23618/61. Heading G5C. A display device or indicator comprises a series of spaced parellel visible bands which may be caused to move across a contrasting background and in which the bands appear to change their width relative to that of the spaces between them. Figs. 1 and ,2 show an indicator comprising three coaxial cylinders, the inner one 1 being fixed, the outer 2 and 3 mounted for rotation about the common axis. Cylinder 1 is uniformly coloured black, whilst cylinders 2 and 3 are of transparent material each provided with a scroll 4, 5 of contrasting colour, for example, white. In the angular position as shown in Fig. 1, an all-white appearance is seen even if both cylinders rotate at the same speed. If, as shown in Fig. 2, one cylinder is rotated relative to the other, the white scroll 5 will overlap white scroll 4 to an increasing extent so that the black surface of cylinder 11 will be visible to a series of black stripes 6 through the transparent portions of cylinders 2 and 3. As shown in Fig. 3 the cylinder 3 is driven by a shaft 7 the speed and direction of rotation of which are proportional to the magnitude and sense of a quantity to be displayed. The cylinder 2 is driven from a shaft 7 via differential 8 which is adjusted manually by control 9 or this could be affected automatically in dependent upon the magnitude of a second variable quantity so that the instrument would convey information concerning two different quantities. In a modification, Fig. 4 (not shown) both manual and automatic control of the width of the strips is provided. In a modification, Figs. 5 and 6 (not shown) the inner cylinder has a white surface with longitudinal black stripes so that at certain angular positions of the two outer cylinders the surface lines of the inner cylinder will be visible, thus enabling two different displays of information to be made on one indicator. In place of using solid cylinders, endless flexible belts 34, 39 moving over rollers may be used as shown in Fig. 8, and the stripes may be made to appear to move up and down, the rollers being driven through differentials. Fig. 9 shows an aircraft display arrangement in which an instrument 45 of the type already described is mounted behind the pilot's instrument panel 46 and an image of the display is projected by optical means 47 on to the windscreen 48 in the pilot's line of sight.
