Title: Improvements in navigational instruments
IPC: G01C19/36
Filed: 1933-03-21
Abstract: 576,412. Gyro - magnetic compasses. BYGRAVE, L. C. March 21, 1933, No. 8563. [Classes 97 (ii) and 97 (iii)] In a gyro-magnetic compass a universallymounted gyroscope orientates, through a follow-up motor, a frame and a magnetic compass bowl and means responsive to the position of the magnetic element relative to the bowl alter the direction of the frame either by applying precessing forces to the gyro or by displacing the follow-up contacts on the frame. As shown, the rotor casing 2 pivots on a horizontal axis 3 in a vertical ring 4, pivoting in turn on a vertical axis 5-5 in a follow-up frame 7, in the lower part of which a magnetic element 16 is pivoted at 17-17. A contact arm 10 on the ring 4 co-operates with contacts 11 on the frame 7 to control a follow-up motor 12 which drives the frame 7 through gearing 13, 1.4, and the distant repeater 38 through contact operating, cams 37. A manually- or automatically-operated rod 20 coacts with a lever 18 pivoted at 19 to clamp the magnetic element at suitable intervals, preferably of one quarter of the free period of the magnetic element, so that damping is achieved. The lever 18 may be flexible so that a contact 21 on the element is first pressed against one or other of two contact segments 22 on the frame 7 and thereafter contacts 18, 23 are closed, thus preventing sparking at the contacts 21, 22. The latter control pneumatic or electrical means for applying a torque to the gyro 2 about the axis 3, resulting in precession about the axis 5-5. As shown, two electromagnets 24, mounted on the frame 7 with their axes intersecting the axis 5-5 and at a horizontal angle to one another, co-operate with spinning disc 25 on the casing 2 and are alternatively energized through leads 26, 27, 28 and contacts 22 to precess the gyro by an eddy current braking effect. A third central electromagnet 31 connected by lead 32 to the lever 18 is adapted to apply a restoring torque about the axis 5-5 when the gyro tilts about the axis 3. In a modification, the gyro may have a gravity or spring control to give a slow precession in one direction and means for precessing it in the opposite direction in response to the position of the magnetic element. In a further modification, the gyro is not subjected -to precessing torques and the resultant wander of the gyro is compensated by a displacement of the contacts 11 relatively to the frame 7. This displacement is effected by a small reversing motor controlled by the contacts 21, 22.

Abstract: 974,617. Controlling clutches. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 1, 1961 [March 11, 1960], No. 8730/60. Headings F2D and F2L. A ratchet gear clutch device for chainconveyers etc. comprises a continuously rotating driving shaft 1 fast with a ratchet wheel 3 and rotatably supporting a driven disc 5 upon which pivots at 8 a pawl 9 biased by a spring 10 to engage the ratchet wheel, a cam follower roller 11 on the pawl running over the inner periphery of a drum 4 rotatably mounted upon the driving shaft and biased by a spring 12 so that a radial arm which it carries engages an adjustable stop screw 13. In the position shown, a swell point 14 in the drum 4 receives the cam roller 11, and the spring 10 biases the pawl 9 out of engagement with the ratchet wheel. By momentarily energizing a solenoid 22, or by other means, a link 17 is slidden downwardly and through a lever connection turns a bellcrank 18 against spring bias to withdraw a detent pawl 20 from engagement with a notch on the periphery of the driven disc 5, accordingly freed for rotation. Following disengagement of the detent pawl 20, the lost motion in connection 16 between the link 17 and the drum 4 is taken up, and continued downward movement of the link turns the drum against the bias of its spring 12, so that the cam roller 11 moves out of the dwell point 14 and the pawl 9 is turned to engage the ratchet wheel 3 for the transmission of drive. When the solenoid 22 or its equivalent is de-energized and released, the driven disc 5 rotates until the cam roller 11 engages an inner cam surface 15 in the drum 4 and reenters the dwell point 14, when the pawl 9 is disengaged from the ratchet wheel 3 and the detent pawl 20 re-engages the notch in the periphery of the driven disc 5, which is accordingly stationed. If, however, a series of impulses is fed to the solenoid 22 &c., the driven disc 5 continues to rotate with the driving shaft 1. Adjustment of the stop screw 13 determines the angular rest position of the drum 4 about the axis of the shaft 1, and hence the angle of rotation through which the driven disc 5 is in positive engagement with the driving shaft 1 during a single revolution. In the form shown, the driven disc 5 is fast with an output sprocket 21. As a modification, more than one dwell point and more than one notch for the detent pawl in the disc 5 may be provided.
