Abstract: 1,273,767. Measuring torsional rigidity. TORAY INDUSTRIES Inc. July 10, 1969 [Jan. 16, 1969], No.34721/69. Headings G1A and G1S. During the measurement of the torsional rigidity of a fibre 3 torque is applied to the fibre through a viscous liquid 6. In Fig. 2 support 2a is fixed and support 2b rotated by coupling of cylinder 5 to cylinder 7 by way of viscous liquid 6, the outer cylinder 7 being rotated by motor 8. The torsional strain is measured by device 4 which may be a pointer. A control system 10 may be provided which compares the output from device 4 with a fixed valve to control the speed of motor 8 to a value which provides a given torsional strain, that value being indicated at 11. In an alternative embodiment, Figs. 3 and 4 (not shown), the motor drives upper clamp 2a directly, the cylinder 7 being held stationary and means are provided to measure the torsional strain of the thread. In the embodiment of Fig. 10, the upper clamp 2a is rotated slowly at constant speed, while the position of the lower clamp 2b is held stationary by automatically controlling the speed of motor 8b. The extent of rotation of the upper clamp, which represents torsional strain, is recorded from potentiometer 4a while the speed of the motor 8b, which represents torque, is recorded from the control circuit on an X-Y recorder. The position of the lower clamp 25 is sensed by photo-cell device 4b shown in Fig. 6, which produces an output proportional to the angular position. This output is compared with a set value in control device 10 and amplified to drive servomotor 39 which in turn drives potentiometer 40. Potentiometer 40 drives pulse-motor 43 by varying the frequency of driving oscillator 41.

Abstract: 761,428. Resilient mountings. WELLS & CO., Ltd., A. Aug. 25, 1955 [Dec. 3, 1954], No. 35062/54. Addition to 740,519. Class 108(3). The wall of the pot of the mounting of the parent Specification is so shaped that a non-linear damping characteristic is obtained. As shown, the surface of the pot is locally deformed in the vicinity of each button 16 to form a conicalshaped recess 20, the apex of which is just engaged, or not quite engaged, by the button 16 in the normal position of the relatively movable parts of the mounting. Under normal vibration, no appreciable engagement occurs between the button 16 and the walls of the recess 20. At resonant conditions however, the amplitude of vibration is sufficient to cause the button 16 to engage the sides of the recess 20 and so modify the damping characteristic. The sides of the recess 20 are straight at 21, 21<SP>1</SP>, and curved at 22. In a modified form of pot, Fig. 1 (not shown) the same effect is attained by giving the walls of the pot an outwardly-bowed shape. Specification 571,026 also is referred to.
