Abstract

608,669. Compression resistances. SPEED MARKETING CO. (SUSSEX), Ltd., and FULLER, R. C. Dec. 19, 1945, No. 34472. [Class 37] [Also in Groups XXXVII and XXXVIII] Fluid pressure is applied to vary the resistance of a block of annular carbon plates 1, Fig. 1, so that the current through an instrument or lamp in series with the block is a logarithmic function of the pressure. The carbon plates are pressed together by a spring 4, while the applied fluid pressure acts on diaphragm 10 and plug 11 to reduce the pressure of the spring 4 and increase the resistance of the pile until at maximum pressure the resistance is infinite.
