Title: Daylight-loading spool for photography
IPC: G03C1/805
Filed: 1930-12-19
Abstract: 375,276. Photographic roll film spools. 1. G. FARBENINDUSTRIE AKT.-GES., Frankfort-on-Main, Germany. Dec. 19, 1930, No. 38320. Convention date, Dec. 19, 1929. Void [Published under Sect. 91 of the Acts]. [Classes 98 (i) and 98 (ii).] A daylight-loading roll-film spool comprises a support consisting of one or more layers of white or lightly-tinted paper coated first with " blanc fixe" or other substratum layer, or with a stripping layer, and then with silver halide emulsion. The paper may be thick to prevent the passage of actinic rays ; or if thin, may be provided with a backing opaque to actinic rays comprising either (1) one or more dyed coatings of a colloid such as a lacquer containing a resin, or an artificial resin, or a cellulose derivative such as the nitrate or acetate, or (2) strips of stained paper, fabric, &c., which may be reinforced with a dyed colloid coating, or may be provided with a plain colloid coating to prevent fouling of the emulsion layer by the paper &c. strip. The paper support may be rendered opaque at its ends only instead of throughout its length. If the emulsion is strippable, negatives produced thereon may be printed after transferring the image-layer to a transparent support. Otherwise they may be copied on positive sensitive material in a copying camera. Alternatively, the emulsion may be chosen so that a positive may be made directly by reversal of the negative on the original support ; or the support may be coated in known manner with a slow positive emulsion unaffected by camera exposure, overlaid by a fast strippable emulsion separated, if desired, by an intermediate layer which may be coloured, the negative layer being stripped off after developing it and printing it on to the underlying positive emulsion.

Suitable conditions for the preparation of such polyethers are a temperature in the range 50 DEG to 150 DEG  C., a gauge pressure of 0 to 80 p.s.i. and an alkaline catalyst e.g. potassium hydroxide. The reaction may be carried out in solution or in the molten state. Suitable polyisocyanates are diisocyanates, tri-isocyanates, the reaction products of excess diisocyanate and a polyhydric alcohol, uretedione dimers and isocyanurate polymers of diisocyanates. Suitable foaming agents are halogenated aliphatic fluorocarbons, and mixtures of these with one another and/or with non-flourine containing hydrocarbons, and water. Suitable catalysts for the polyurethane forming reaction are triethylamine, dimethylbenzylamine, dimethylphenylethylamine, tetramethyl-1 : 3-butanediamine, triethylenenediamine; N - alkyl-morpholines, N - alkylpyrrolidines, 4 - dimethylaminopyridine, dibutyltindilaurate, dibutyltindiacetate iron acetylacetonate, manganese acetylacetonate, stannous octoate, lead acetate and lead octoate.  Specified suitable additives are surface active agents, e.g. silicone fluids, oxyethylated phenols and fatty alcohols and block copolymers of ethylene and propylene oxides; foam stabilizing agents, e.g. ethyl cellulose; colouring matters; fillers; plasticizers; flame retardants, e.g. tri-(b -chloroethyl)phosphat and antimony oxide; and antioxidants, e.g. tert.-butyl catechol.  The example describes the preparation of a foam polyurethane from polypropoxylated N-methyl glucamine, phosgenated crude diaminophenylmethane, tri-(b -chloroethyl)phosphate, dimethyl siloxane ethylene oxide propylene oxide block copolymer and monofluorotrichloromethane.

[Also in Division H3] In a synchronous detector a reference voltage renders two rectifiers of the detector conductive simultaneously and a constant positive or negative D.C. bias is added to it to render the output non-linear to compensate a non-linear analogue output of a transducer, e.g. thermocouple, modulating the carrier input. In Fig. 6, reference voltage V D  in series with bias-E is applied to rectifiers D5, D6 to produce, in conjunction with an input from transformer M, a non-linear output, but as the non-linearity is opposite to that required to compensate a thermocouple non-linearity, the output is combined with a larger linear output of opposite polarity derived from a larger reference voltage V L  of opposite phase applied, together with the input, to rectifiers D3, D4 so that the non- linear output is subtracted from a linear output. Alternatively bias source E may be replaced by a shunt R-C network in series with V D  and by resistors in series with each of rectifiers D5, D6, the R-C network resistor being variable to vary the non-linearity.
