Abstract: 345,575. Sensitive materials for colour photography. I. G. FARBENINDUSTRIE AKT.-GES., Frankfort-on- Main, Germany. June 4, 1930, No. 17245. Convention date, June 4, 1929. [Class 98 (ii).] Pictures in two or more colours are produced by printing from component colour-record negatives on to layers sensitized with esters or estersalts of leuco dyestuffs. The layers may be exposed when moist or dry, and may contain as an accelerator a substance such as an organic nitro-compound or collodion which has an oxidizing action during exposure. The dye images may be fixed by washing as with alcohol or water. If a colloid such as gelatin is used as the vehicle of the sensitive bodies, the layers are differentially hardened on exposure to light, and may be developed as wash-out reliefs. The component positives may be produced in succession on the same paper or transparent base by resensitizing the base for each component; or may be printed on separate transparent sheets which are subsequently superimposed in register. A mercury-vapour lamp is preferable for printing. As sensitizing bodies for tricolour pictures may be used: Indigosol golden yellow ICK, Indigosol blue 06B, and Indigosol pink IR extra, each in 3 per cent aqueous solution. Reference is made to the use of ordinary leuco-dyestuffs for producing pictures in one or more colours, and to the use of sulpho-esters of leuco-dyestuffs for producing monochrome photographic tracings.

Abstract: 1394602 Record reader DATA RECOGNITION Ltd 14 April 1972 17346/72 Addition to 1317885 Heading G4M [Also in Division H3] An optical record reader has light transmitted to a transparent plate 24A via optical fibres 42 and has optical fibres 43 transmitting reflected light to a photo-cell 52 on a printed circuit board 51. Light from a source 53 is transmitted to a plurality of positions via channels 47 and to a reference photo-cell 52. Reflected light from each position is transmitted to a respective photo-cell. The reference photo-cell is used to modify the supply to the light source to compensate for variations in intensity, e.g. due to ageing and to compensate for temperature variations varying the sensitivity of the transistors. Each record is pressed against a guide by angled rollers (Fig. 2, not shown), and passes over surface 24 of plate 24A. The record has locations preprinted in colours to which the reader is not sensitive and each required location is marked by a line through the location. Each mark is situated between two clock pulse marks 65a, 65b in a clock pulse track. A faulty mark has the lower half of a location blacked out and read circuitry is arranged to cancel this mark. The final clock pulse 67 is wider than usual and is detected by blanking out two adjacent windows (41b, 41c, Fig. 2, not shown), of the clock track reader. Pulses representing marked data are fed to two threshold detectors arranged to operate at different voltages, one representing a definite mark, the other a doubtful mark (Fig. 9, not shown). The outputs of both detectors may be stored and compared on read-out. An item of data having both marks is correct, one having only one mark is either rejected or referred to an operator for checking.

Title: Improvements in the generation of chlorine dioxide
IPC: C01B11/02
Filed: 1944-07-07
Abstract: Chlorine dioxide in a state of dilution with carbon dioxide is generated by reacting carbon dioxide with an inorganic chlorite, e.g., sodium or calcium chlorite, in the presence of water vapour. The concentration of the chlorine dioxide is controlled by regulating the rate at which the carbon dioxide is brought into contact with the chlorite.  The water vapour and carbon dioxide may be premixed prior to contacting the chlorite and the rate at which the mixture contacts the chlorite exceeds the rate at which the carbon dioxide will react the chlorite.  The carbon dioxide may be obtained by the sublimation of solid carbon dioxide, which is particularly suitable where the chlorine dioxide is applied to the sterilization of food in conjunction with the refrigeration thereof.ALSO:Food is sterilized, especially during refrigeration where solid carbon dioxide is used as a refrigerant, by a carbon dioxide-chlorine dioxide mixture (see Group III).
