Title: Improvements in or relating to torque meters
Inventor: HEGARTY WILLIAM
IPC: G01L3/12
Filed: 1965-04-15
Abstract: 1,129,583. Photo-electric torque measuring apparatus. SAUNDERS ROE DEVELOPMENT Ltd. March 15,1966 [April 15,1965], No.46507/67. Divided out of 1,129, 582. Heading G1A. The torque of a shaft is measured using a photo-electric system sensitive to the amount of angular twist between two positions along the length of the shaft. The shaft 1 is mounted to rotate in bearing 13 associated with a cylindrical housing 12 fixed in space by its connection to supports 15. Inside the housing 12, is mounted a self-luminous light source 4, comprising a phosphor-coated envelope containing radio-active gas to activate the phosphor. The inner wall of the housing carries a single photo-cell 25, photo-conductive or photovoltaic, mounted to receive light from the source. Interposed between source and detector are two cylindrical skirts 10, 24, each having a series of equally spaced slots. The skirt 24 is attached to the shaft within the housing 12 and skirt 10 by means of tube 5 at a location spaced from the housing. During rotation of the shaft, any torque will cause misalignment between the slots of the skirts 10, 24 as they pass between source and detector, resulting in a decrease from the high intensity level obtained with correct alignment. A galvanometer 19 displays the r. m. s. value of the alternating photo-cell output which is representative of the torque. Modifications are possible e. g. more than one source can be used, or an annular source, or one coincident with the axis of the shaft. Reference photo-cells may be provided to compensate for source intensity decreases and temperature variations. The apparatus can be adapted for use as a tachometer while giving torque readings so that power measurement is also possible.

Abstract: 1,031,870. Differential gears. W. E. SALZMANN. Nov. 30, 1964 [Dec. 2, 1963], No. 48539/64. Heading F2D. In the positive locking bevel differential for motor - vehicles according to Specification 936,830, in which pins 1 passing through holes in the driving planet cage are movable by a carrier ring 2 to engage apertures in a bevel sidewheel, the pins and apertures having faces inclined at an angle near to self-locking to disengage automatically on overload, control of the carrier ring 2 is effected by face cams 8, 9 (Fig. 3, not shown), (replacing the pivoted yoke of the prior Specification), which are relatively-turned by a Bowden cable 12 and/or linkage to axially thrust the locking pins into engagement with the bevel side-wheel 3. The carrier ring 2 rotates in a stationary thrust-ring 4 which is secured against rotation by a spring steel arm 5 fast at 6 with the fixed casing 7, and to which is secured, or integrally formed, the face cams 8. The face cams 9 are secured to, or integral with, a thrust cage 10 mounted for limited rotation on a bearing sleeve 11, the control cable 12 being connected at the rim of the cage 10 through a pre-stressed compression spring 13 which permits automatic disengagement on overload. The flanks of the face cams 8, 9 are shaped to provide a two-rate movement, the flanks being initially steep followed by a shallow part which effects the actual engagement of the pins 1 and is inclined at an angle slightly above the angle of selflocking. Compression springs 14 and 15 return the cable 12 and ring 2 to their disengaged positions. Operation may be through a pedal or hand lever with or without a detent, and two or more differential locks, having separate control cables, on a vehicle may be connected to a common operating lever either directly or through a two-armed rocking lever with equal or unequal arms or a compensating pulley, such that on automatic overload disengagement of one of the locks, the spring 13 of the other lock is more strongly pre-stressed by automatic displacement of the cable 12 to increase the automatic disengaging load of the second lock, reengagement of one or both locks being effected by a brief disengagement of the vehicle clutch or momentary release of its throttle pedal allowing automatic operation of the springs 13. Fig. 4, (not shown) illustrates a compact arrangement in which the thrust-ring is mounted directly for limited rotation on the outer bearing race and the carrier ring consists of synthetic plastics material in which the lock pins are moulded or secured by adhesive. Additionally the thrust ring, thrust cage and face cams separately or integrally formed may be of bronze or plastics material. Manual operation may be replaced by pneumatic, hydraulic or electromagnetic control with or without the safety spring 13.
