Abstract: The invention concerns an optical grating drive apparatus wherein a carriage for multiple diffraction gratings is movable between a plurality of locations, there being stops to limit carriage movement at such locations in which different gratings are selectively presented in the path of an incident beam; also a plurality of cam followers are shiftable relative to rotary cam means between positions in which different followers selectively engage the cam means and are displaced in response to cam means rotation; the followers and carriage have operative interconnection such that when a selected follower is engaged with the cam means the carriage may occupy alternate locations in order to selectively present corresponding gratings to the beam path; and displacement of a selected follower in response to cam rotation effects rotation of a selected grating in the beam path.

Abstract: The disclosure concerns the provision of means for significantly reducing certain inaccuracies associated with circular dichroism measurement, and in which a certain signal (alternately proportional to sample characteristic transmission values for predominantly right-circularly polarized light and leftcircularly polarized light) is processed to produce a modified signal proportional (within a predetermined additive constant) to the logarithm of the certain signal, the AC component of the modified signal being used in indicating the value of circular dichroism.

Abstract: Fourier spectroscopy is used in the measurement of circular dichroism, the method involving the use of an interference polarization modulator which is characterized by production of negligible amplitude modulation in the absence of dichroism in the optical train that follows the modulator and in the detector. Either linear or circular dichroism in that region of the instrument will convert the polarization modulation into amplitude modulation. The polarization modulation is characterized by a different frequency for each wavelength of the radiation, thus the signals caused by the interaction of the radiation with dichroic sample may all be recorded simultaneously and may subsequently be ''''unscrambled'''' to derive the inverse Fourier transform of the ensemble of frequencies constituting the complete signal, and thus obtaining a transmission spectrum corresponding to the dichroism. The transmission spectrum in turn, in the case of the circular dichroism, may be converted into dichroism by dividing by the ordinary transmission spectrum (corresponding to ordinary absorption) which may be derived by ordinary Fourier spectroscopy.

Abstract: The method of making a glass electrode more sensitive to K than to Na in electrolytic solution includes the steps of forming a glass melt to have an initial composition of K2O, A12O3 and SiO2 where the mol percents of K2O and Al2O3 are chosen to optimize sensitivity ratio (K sensitivity to Na sensitivity) with low electrode output drift; digesting the melt for an extended period to substantially reduce the electrode output drift rate; and forming the electrode from the digest melt.
