Abstract: 435,257. Expanding - - pulley gearing. LINDSAY, H., 47, Queen's Road, Bradford, Yorkshire. Feb. 16, 1935, No. 5114/34. [Class 80 (ii)] Expanding V-belt pulley gearing is rendered automatic by centrifugal weights 5 assisted by springs 10. The pulley shown has one movable flange 2 which is closed towards the fixed flange 1 by the heels of levers 6 which carry the weights 5. The levers 6 are supported on pivots 7 turning with the pulley. A form is described in which the levers 6 are pivoted upon the movable flange and abut against a non-yielding part. In Fig. 4, the improved pulley 2 is shown supported along with a driving electric motor M on a platform P turning about a fixed pivot 16 against a spring 17. The tension of the belt 9, which drives on to a flat pulley 14, increases with the speed. Consequently an arm 17x of the platform P rises as the speed increases. A stop 18 limits the rise of the arm 17x and the maximum speed of the automatic gearing is controlled by adjusting the stop 18 by means of a screw 19 and hand wheel 22. The spring 17 may be omitted, and all speeds may be effected positively by fitting a nut on the arm 17x engaged by the manual screw 19.

Abstract: 1,138,433. Nuclear reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE. 6 Feb., 1967 [22 Feb., 1966], No. 5603/67. Heading G6C. [Also in Division H4] A system for measuring the volume percentage of argon in liquid sodium nuclear reactor coolant comprises means for determining the velocity of sound in the mixture at two different static pressures. A measurement pipe 3 links the suction and delivery pipes 14, 15 of coolant pump 16 and comprises horizontal portions 1, 2 separated by valve 4 giving a fixed pressure drop between the two portions. The pressures and temperature in the portions 1, 2 are measured by means not shown, and flow rate in pipe 3 is measured by an electromagnetic device 8. The acoustic velocity in the mixture in sections 1 and 2 is determined by propagating acoustic pulses in the mixture, using electromagnetic pump 18, and timing the arrival of the pulses at piezoelectric transducers 9, 10, 11, 12, using an oscilloscope the screen of which is photographed. A given mathematical relationship establishes that, for bubbles of the size generally encountered in the coolant, acoustic velocity in the mixture is a function of both pressure and mean bubble size. The measurement of velocity at two pressures enables a non-ambiguous indication of the gas content and mean bubble size to be obtained by reference to acoustic velocity/gas content/bubble size curves derived by calibration or calculation.
