1,007,613. Electric load cells. WESTERN ELECTRIC CO. Inc. Aug. 2,1962 [Aug. 21,1961], No. 29682/62. Heading G1N. [ Also in Division H1] A load all comprises a body of n-type semiconductor piezo-resistive material having a composition of between 13 and 19 atomic per cent of silicon and the remainder germanium. The preferred proportions are 16. 6% silicon and 83.4% germanium and a body 13 of such composition may be provided with electrodes 14,15 and used to indicate the stress exerted on a specimen 10 by loading members 11,12. The cell is connected in series with a current measuring instrument 18 to give an indication of the loading. |
