Abstract

868,886. Measuring electrically. PERKINELMER CORPORATION. Dec. 21, 1959 [Dec. 19, 1958], No. 43360/59. Class 40 (1). [Also in Group XL (b)] A signal dependent upon the position of an optical compensating wedge in a spectrophotometer is derived by mechanically coupling the wedge to a capacitor 59 in the grid circuit of an R.F. oscillator 49. The signal appears on a potentiometer 61 in the oscillator anode circuit
