Abstract: 1485785 Fertiliser spreader VICON NV 20 Sept 1974 [26 Sept 1973 17 April 1974] 41054/74 Heading AID A device for spreading fertiliser comprises a hopper 1 having at least one outlet port, a spreading member 2, and a closure member in the form of a disc 6 having an opening and operated by a lever 16 characterised such that in one position of the lever 16 (dashed lines - in operative position) the opening does not communicate with the outlet port and in an operative position (solid line) the degree of communication between the opening and the outlet port can be varied by operating a linkage 7 which comprises a first member 8 or 9 and a second member 9 or 8 screwably cooperable with the first member for varying the degree of communication between the opening and the port. Preferably the first member is a screw spindle 8 having resilient tags 14 and the second member is a rotatable screw sleeve 9 having recesses 15 engaged by the tags 14 at different positions. In the embodiment of figure 2 the screw sleeve 9 is pivotally connected to the disc 6 via a rod 10 whereby movement of the sleeve varies the degree of communication between the port and the opening. The screw sleeve 9 may be connected to the lever 16 while the spindle 8 is integral with the rod 10. In another embodiment (Fig. 6) the spindle 8 is coupled to the plate 6 by an ear (21) Fig. 8 (not shown) remote from the end of the spindle 8 which is connected to the lever 16, and the sleeve 9 with its stop 20 cooperatively engages a stop 19 mounted on a frame of the device. The stop 19 is adjustably mounted on the frame by slots 22 so that in a zero position of the sleeve 9 and in a zero position of the disc 6 (viz, the closed position of the disc 6) the stop 19 is shifted so that it abuts the stop 20 whereby moving the lever 16 to the operative position moves the spindle 8 over a distance defined by the stops 20 and 19 to adjust the disc 6 over this distance. Alternatively the sleeve 9, the screw spindle 8 and the stop 19 may be arranged symmetrically in order to use the stop 19 for defining the maximum opening of the disc 6. The sleeve 9 may have the lugs 14 and the spindle 8 may have the recesses 15. Also, the number of lugs and recesses may be varied to vary the number of positions of the disc 6.

Abstract: 960,437. Gyroscopic apparatus. SPECIAL DEVICES LABORATORIES Inc. Dec. 9,1960, No. 42433/60. Heading G1C. [Also in Division F2] A gyroscope comprises a base 1 to which is fixed a columnar pedestal 14 carrying bearing means for at least one degree of freedom mounting of a gimbal 27 which is in the form of a sleeve surrounding the pedestal 14 for pivotal movement about a diametral axis 26 normal to the axis of pedestal 14, a rotor 41 being journalled on the outside of the gimbal 27 for spinning about an axis which normally coincides with the pedestal axis. As shown applied to a rate of turn gyroscope, the restraining springs 61, 62, are anchored between the base 1 and studs 59, 60 secured to the gimbal 27, precession being detected by pick-offs comprising coils such as 81, 83, encircling cores 71, 73 co-acting with arms 55, 56, depending from the stator sleeve 48 on gimbal 27. Damping is effected by damping fluid which fills the small gap between the inner bore of gimbal 27 and a spindle portion 23 of pedestal 14. A nylon or other insert 38 having a relatively high coefficient of thermal expansion is closely spaced from the cap 37 on gimbal 27 so that on precession of the gyroscope, damping fluid flows from one side of the insert 38 to the other, the size of the aperture being temperature dependent and compensating for the varia tion of damping fluid viscosity with temperature. The three-phase current for the stator of the rotor spin motor is fed through pins such as 87 in the base 1, and coiled wires, not shown, but may be passed through the springs 61, 62. In the latter case the springs are insulated and either four springs are provided, two on each side, or three springs, two on one side and one, equal in strength to the other two, on the other side. In a modification in which the gyroscope is provided with a further degree of freedom, shaft 26 pivotally supports a yoke on which the gimbal carrying the rotor is pivoted about an axis at right angles to both shaft 26 and the spin axis.
