Filed: 1940-06-24
Abstract: 544,064. Colour photography. KODAK, Ltd. (Eastman Kodak Co.). June 24, 1940, No. 15161/39. [Class 98 (ii)] A dye or dye-forming substance such as a colour development coupler incorporated in an alkaline photographic layer having a watersoluble binder such as gelatine is rendered less liable to diffuse by coating the layer from an aqueous solution of the binder containing the dye or dye-forming substance and also containing polyvinyl phthalate or cellulose acetate phthalate substantially homogeneously distributed throughout the layer. The dye may be a sensitizing filter, or anti-halation dye. The process is particularly applicable to multilayer or mixed-grain material with or without an intermediate or overcoating layer containing filter dyes. In an example the sodium salt of p-phenylbenzoylacetonitrile and polyvinyl phthalate are incorporated in an alkaline gelatine silver bromide emulsion. The gelatine is hardened with formaldehyde. A second emulsion layer is coated on the first layer, and on processing with p-aminodiethylaniline the magenta dye is mainly generated in the lower layer. Specification 542,507 is referred to.

Abstract: 1492169 Frequency selective voltmeter FELTEN & GUILLEAUME CARLSWERK AG 14 April 1976 [10 May 1975] 15227/76 Heading G1U A frequency selective voltmeter 1, 2, 3, 4, 5, is modified by the inclusion of a switch 11 whereby, for calibration purposes, the filter 2 can form part of an oscillator 2, 3, 6, 10, controlled by a further loop 7, 8 to produce a voltage at the centre frequency of the filter, and having a reference amplitude set by a standard cell 9. Thus, this arrangement replaces the need for a standard A.C. voltage having a frequency accurately set at the centre of filter 2, by the much less stringent need for a standard D.C. cell 9. In the calibrating mode, switch 11 is set to complete the oscillator loop 2, 3, 6, 10 and to isolate the input 1. The amplitude of the signal in the loop is detected 7, compared 8 with the standard cell, and automatically brought 6 to the standard level. Hence, in the calibrating mode, the meter 5 should indicate the standard level, and if it does not it can be appropriately adjusted.
