Abstract: 1529309 Apparatus for winding piano strings R DUBOIS and P DUBOIS 24 Nov 1975 [28 Nov 1974] 48185/75 Heading B8G [Also in Divisions D1 and G5]  To wind a piano string, a member is rotated on a hollow shaft to orbit a reel of auxiliary wire to helically wind the wire on a core wire running through the shaft, the running core wire upstream of the shaft having been deformed in a fixed plane to prevent its rotation during winding. Advancing steel core wire 4, bent by pulleys 5 to prevent rotation, is wound with copper wire 8 from reel 7 on disc 1 rotated via belt 6 by hand crank or an electric motor. Disc 1 may have different diameter belt pulleys to enable the disc to be rotated at different speeds. Spring-biased arm 9 tensions wire 8. Counterweight 11 may be replaced by a further spool 7 for the simultaneous winding of a second wire 8. A device may prevent back-rotation of disc 1. The device may be reversible to permit clockwise or anti-clockwise winding of the auxiliary wire.

Title: Preparation of printing surfaces
IPC: B41C1/05
Filed: 1972-10-25
Abstract: 1393300 Facsimile apparatus CROSFIELD ELECTRONICS Ltd 16 Oct 1973 [26 Oct 1972] 49250/72 Heading H4F In an image-reproduction system in which a gravure printing surface preformed with a regular grid of gravure printing cells of the type described in Specification 1,229,243 is line scanned by a modulated laser beam, to avoid moire interference patterns being produced the spacing between adjacent lines of the lineby-line scanning of the printing surface is equal to, or a simple fraction of, the grid spacing of the gravure printing cells when the grid is projected perpendicular to the scanning lines. The laser beam scanner is preferably directly coupled to an analysing scanner which scans an original to be engraved on to the printing surface. To maintain the predetermined relationship between the grid spacing and the spacing of the scanning lines a pair of illuminated reference screens, each carrying a transparent and opaque pattern identical to the pattern of gravure cells on the printing surface and displaced in opposite directions relative thereto, are transversely moved with the scanning laser beam over the printing surface and the degree of alignment between the pattern of cells and the screen patterns are photoelectrically detected by two photo-detectors, the transverse scanning rate of the laser beam being adjusted to maintain a constant difference, e.g. zero, between the two output signals from the photo-detectors. The grid of printing cells may be aligned with the scanning lines, at 45 degrees or at any other angle thereto having a rational tangent, e.g. <SP>1</SP>/ 3 . For helical drum scanning the helix angle must be added to (or subtracted from), the angles which the lines of cells make with the scanning lines. Where the analysing scanner output video signal is stored, e.g. on a magnetic tape, before being applied to the laser beam scanner, signal interpolation may be necessary using a three line capacity buffer store.

Abstract: 1286157 Time-division multiplex radio systems KOKUSAI DENSHIN DENWA CO Ltd and FUJITSU Ltd 10 Oct 1969 [11 Oct 1968] 49993/69 Heading H4L A synchronizing arrangement for a station forming part of a time-division multiplex communication system, and particularly for an artificial satellite system with time-varying path lengths, compares a stored digital value of predicted burst time in the frame with the actual received time and effects an arithmetic correction before re-writing the prediction in store. As shown in Fig. 3 the predicted timing is read from 11 into 13 before each burst and compared at 14 with the contents of the continuously counted-up frame bit counter 12, and when equality is detected the control identifying data UWP transferred to 16 starts to shift and is compared with the incoming control word. One of D 1 -D n+1  is energized according to the variation of timing from the predicted timing. This information is passed to adder/ subtractor 19 which updates the prediction before writing back. In a further embodiment (Fig. 5, not shown), the predicted times for the reference burst and the burst originating from the particular station under control are fed to an arithmetic unit together with the nominal time separation, and if the actual time separation differs from the nominal the transmission time is varied accordingly in unit steps until synchronization is achieved, the predicted receipt times being adjusted correspondingly. Continued correction of transmission is delayed until its effect on received timing is known (from the estimated range) to have taken place.

As shown, the member is a rod 20, pivoted at 22 and carrying a vane 32 of non-magnetic material located together with the particles 40 between the poles of a permanent or electro-magnet 34. The position of the rod 20 is adjustable by means of a moving coil motor 24 and the adjusted position is indicated by pointer 58 and scale 60 and is transduced into electrical signals by a Hall effect generator 50. Instead of motor 24, a manual force applied at pointer 58 may be used to adjust the position of rod 20. Uses of the device An input signal from a computer or analog process controller, Figs. 5 and 6 (not shown), is used to energize the motor 24, the output from generator 50 being used firstly to provide an output control signal for a fluid-control valve and secondly to provide a feedback signal opposing the input signal. When the feedback signal reaches a level which cancels the input signal, the motor 24 is de-energized and rod 20 comes to rest in the commanded position. A three-way switch may be provided to permit the device to be selectively controlled by a computer or by a back-up analogue processor or manually, Fig. 7 (not shown). Instead of pointer 58, the end of rod 20 may carry a pen for marking a moving record strip. A number of such pen-recorders may be inter-connected in a time-sharing network, Fig. 8 (not shown).
