Title: Toner particles of photoconductive pigment in matrix - of transparent insulating binder transporting charge carriers, for high strength
Inventor: HONJO SATORU
IPC: G03G9/09
Filed: 1974-02-14
Abstract: Photoconductive toner particles each consist of an intimate mixt. of a photoconductive pigment (I) and an insulating binder (II), which can transport charge carries if these are introduced into (II) from (I), the toner contng. 2-30, pref. 5-20 vol. % (I), whilst (II) is transparent to light in the region of the spectrum for which (I) is sensitive. (II) pref. has an absorption coefft. 1.3 x 102 mm-1 and contains over 5, pref. 5-20 (but opt. 50-100) wt. % (organic) Lewis acid (III) (as sensitiser). The binder can also consist of a transparent surface coating, together with a transparent core of plastics, glass, a ceramic material or a hydrocarbon vapour, in which case the proportion of (I) is 2-43 vol. pts./100 vol. pts. binder and the (I)/(II) mixt. constitutes 0.01-75 vol. % of the toner. Since the particles have a low (I) content, they have high mechanical strength and can be used repeatedly without impairing their properties. They also give images with good contrast, even on dark coloured or black substrates.

Title: Optical attenuation measuring system for oceanic research etc - enables attenuation differences and quotients to be measured
Inventor: KROEBEL WERNER PROF DR
IPC: G01N21/25
Filed: 1975-03-12
Abstract: Two light sources of different wavelength direct their beams through two partially transmitting mirrors so that identical beam lengths are obtained in the measuring medium. One light source is modulated in opposition to the other at a frequency so that the alternating light forms algebraic vectors for processing in photodetectors as complex alternating voltages or currents, e.g. in a two-phase bridge circuit. The attenuation difference of the beams of different wavelength in the measuring medium is measured over a phase angle resulting from the vector difference of the attenuated beams in the medium. One light source, e.g. the second is controlled so that either the primary intensities of the sources remain identical or their intensity ratio is kept constant.
