Title: Improvements relating to road vehicle earthing devices
Inventor: PLANT WILLIAM HENRY
IPC: B60R16/06
Filed: 1961-12-06
Abstract: 1,037,402. Vehicle earthing devices. W. H. PLANT. Feb. 26, 1963 [Dec. 6, 1961; Nov. 16, 1962], Nos. 43666/61 and 43447/62. Heading B7H. A vehicle earthing device has means to raise a road engaging element when the vehicle is moving and not almost stationary. The device comprises a cylinder 11 connectible by tube 13 to the inlet manifold of a vehicle engine and containing a piston 10 with a piston-rod 18 provided with relieved portions 22, 23 on either side of a rack portion 21 engageable by a pinion 24 on shaft 25 to which is attached arm 26 with road-engaging element 27. In operation, when the engine is ticking over the high manifold depression draws the piston to the left against the force of spring 16 and the element 27 hangs down as shown. As the throttle is opened the manifold depression decreases, allowing the spring 16 to push the piston to the right together with the rack 21 which rotates the pinion 24, raising the element 27. When the engine stops, spring 16 pushes the relieved portion 22 of rod 18 below pinion 24, allowing element 27 to hang down. The tube 13 may alternatively be connected to the inlet manifold adjacent the throttle butterfly valve so that there is no vacuum when the engine is ticking over and a lighter spring 16 may be used and in a modification the rack and pinion may be replaced by a cam and follower. In a further construction (Fig. 3, not shown) in which the cylinder is connected to the inlet manifold adjacent the throttle butterfly, the road-engaging element is connected by a flexible cable to an arm which is resiliently connected to the arm engaging part of the piston. A warning lamp may be provided to indicate that the ground-engaging element is lowered.

Title: Improvements relating to x-ray equipment
IPC: H05G1/66
Filed: 1960-12-21
Abstract: 893,654. Control of A.C. motors. PICKER X-RAY CORPORATION, WAITE MANUFACTURING DIVISION Inc. Dec. 21, 1960 [Jan. 4, 1960], No. 43910/60. Class 38 (3). [Also in Groups XX and XXXV] A control circuit allows the H.T. supply to be connected across a rotary anode X-ray tube only when the anode is rotating at a definite minimum speed. The stator of the motor driving the anode has two parallel connected windings 10, 11. Winding 10 is connected directly across an A.C. source L 1 , while winding 11 is connected to the same source via a phaseshifting capacitor 14 and a switch 18 which is initially in the position shown. Thus initially the motor is driven by the current in both windings 10 and 11. Also connected to the source L 1  is a trigger valve 20 acting as a time delay; when the grid bias builds up sufficiently for the valve to become conducting, solenoid 19 is energized, which changes over switch 18 opposite to the position shown. This is arranged to occur when the anode rotation has reached the required speed; the anode is now kept rotating satisfactorily by the current through the single winding 10, since winding 11 is now isolated from the current supply. This second position of switch 18 connects winding 11 to a rectifier bridge 25 whose output is fed to a relay 35 controlling a contact 36; this closes to trigger off a timing unit 37 which operates a solenoid 40 and switch 41 to apply the H.T. source L 2  across the X-ray tube 38. Relay 35 is energized by a back e.m.f. induced in winding 11, which is proportional to the speed of the anode, and operates relay 35 if it is high enough. If the anode is not rotating fast enough, this back e.m.f. will not be sufficient to energize the relay, and the H.T. will not be applied across the tube. In the case of a circuit break between the windings and the point 33, a relay 30 opens a switch 24, which prevents A.C. from the source L 1  from passing to the rectifier bridge and so connect the H.T. to the X-ray tube at the wrong time.
