IPC: G01C19/38
Filed: 1917-04-02
Abstract: 127,055. Gray, J., and Gray, J. G. April 2, 1917. Gyroscopic apparatus.-In instruments required for navigational and other purposes, and comprising a system precessing about a vertical axis, the precessing system has its centre of gravity eccentric both to the axis of precession and to the axis of rotation of the fly-wheel, so that tilting of the normally vertical axis will produce a couple about this axis by direct action independently of precession. The application of the invention to the stabilizing of a frame 4 mounted on horizontal pivots 7 is shown in Fig. 1; the gyroscope 1 is mounted on vertical pivots 2 within the frame 4 and carries a weight 6 offset from the axis 2-2 and from the axis of rotation of the fly-wheel. Sighting wires 10, 11 are carried' by the frame 4 and the upper of the pivots 2 carries a crank 5 normally in the plane of the frame 4. In order to maintain the frame 4 vertical the operator rotates the base 12 upon which the frame 4 is pivoted so as to maintain the crank 5 in the plane of the frame 4. The application to a compass is shown in Fig. 2. The frame 4 carrying the gyroscopic system 1 mounted to precess about the vertical axis of pivots 2, 2 is mounted on pivots 7 in a frame 8, which is maintained in the vertical plane by a gyroscope system 9 constructed as described in Specification 14032/15. The frame 4 is maintained in alinement with the frame 8 by means of a follow-up system comprising a motor 19 turning the whole system of frames about its vertical pivot 15. A torsion wire 2<1> is provided for the upper pivot 2 of the gyroscope 1. In another construction, damping of the meridianfinding gyroscope is produced by spring connexions between it and the frame carrying the stabilizing gyroscope. The Provisional Specification describes' other methods of damping. One form comprises an electro-motor, which carries torque-producing air-vanes and is automatically switched into action from the contacts of the follow-up system: alternatively, a loose ball-bearing sleeve is mounted on one of the vertical bearings of the gyroscope and is similarly rotated to produce a retarding torque. Specifications 1240/15, 17725/15, and 125,660 are referred to.

[Also in Division H1] A combined valve and electric switch device for process control such as in a continuous flow automatic system for chromatographic analysis, comprises a number of resiliently compressible tubes 86 through which different eluting liquids are pumped, and means for occluding the tubes consisting of an array of cam-shafts 54 arranged round a rotatable support 42, 44, 46, so that the tubes are compressed against a platen 68. Those cams such as 130, between the support plates 44, 46, are arranged to operate snap-action switches 106, 108, 110, 112 through pivoted arms 116, 118, 120, 122 to control a drive motor 134 and pumps supplying the tubes. The camshafts are releasably mounted in the support by spring clips 58, for replacement through an access door 133. The phasing of the switches is adjustable by screw tappets 124, Fig. 5 (not shown). Spacers in place of some of the cams 130 are arranged to miss the switches. The arm may have a narrow follower part 128N so that it drops behind each cam, or a wide follower part 128W so that it is held actuated by one cam until engaged by the next succeeding cam. The occlusion of the tubes 86 is similarly controlled, in that a spacer, following an occluding cam 98, will allow the tube to open, whereas two following cams 98 will hold the tube occluded continuously. The direction of motion of the cams is counter to the flow direction so that no pumping action occurs. The drive motor is energized through a latching relay (140), Fig. 5 (not shown), initially by a pulse from an external switch. The latter may be incorporated in a clock mechanism, with a continuously advanced punched tape. The tubes are located by grooved blocks (82) and collars (88) adhered to the tubes. Automanual selector switches (146) are provided, with a manual push button control (148), Fig. 3 (not shown).
