Abstract

1,012,708. Indicating-apparatus. MECHANISM Ltd. June 25, 1964 [May 3,1963], No. 17653/63. Heading G1J. Apparatus for measuring the rate of change of one variable with respect to another comprises a drum 16 rotating at a constant speed, a lever 12 moved about its pivot 13 in response to the pressure in a capsule 10, a castor roller 15 pivotally connected to the lever 12 and contacting the drum 16 so that as the lever 12 moves the castor 15 longitudinally of the drum 16 the castor will pivot and move a pointer 20 against a scale 21 to indicate the rate of change of the pressure with respect to time. The castor roller 15 is rotatably mounted in a frame 14 pivoted on the lever 12 and the castor action is obtained by offsetting either the pivotal axis or the drum axis from alignment with the roller axis and can be increased if none are aligned. The drum 16 could be replaced by an endless belt or by a toroid. The pointer 20 may be adapted to record and may be included in a control warning system of apparatus being monitored.
