Abstract

973,125. Resistance networks. KEINATH INSTRUMENT CO. July 5, 1962 [July 17, 1961], No. 25757/62. Heading H3U. [Also in Division H2] An impedance and voltage divider 50 comprises a series impedance member 51 with individual impedance segments 52 ... 58, a plurality of impedances 59 ... 66 connected to the ends of the segments 52 ... 58 and to contacts 67... 74, and slidable contact means moving over the contacts 67... 74 to provide stepwise tapping of the impedance segments in at least four times as many steps as the number of contacts. The slidable contact means comprises two fixedly speech contacts 76, 77, arranged such that the voltage at point 80 changes in “ volt steps as contacts 76, 77, move over the surface of contacts 67... 74. Three or more slidable contacts may be used, spaced to give voltage changing in 1/6 or 1/ 8 volt steps. The capacitors 81, 82, 83 provide for more gradual voltage change.
