Title: Photographic products and processes
IPC: G03C8/16
Filed: 1970-05-06
Abstract: 1308492 Photographic colour transfer POLAROID CORP 6 May 1970 [9 May 1969] 21900/70 Heading G2C Photographic colour transfer images are formed by developing a photo-sensitive element which includes an exposed silver halide emulsion with aqueous alkaline processing composition in the presence of (1) a first colour providing material which is normally diffusible in the composition but which resets during development to form a non-diffusible colour providing material in the exposed (or unexposed) areas, and (2) a second colour providing material which is normally non-diffusible but which reacts during development to form a diffusible colour providing material in the unexposed (or exposed) areas, thus forming 2 imagewise distributions of diffusible colour-providing material each in the unexposed (or exposed) areas, and transferring at least part of each distribution to a superposed image-receiving stratum. In a first embodiment (1) is a diffusible dye developer which on development forms a non-diffusible oxidation product, and (2) is a dye which reacts with the silver complex to form an oxidation product which undergoes infra-molecular ring-closure with the elimination of a diffusible dye moiety; there may be used development nuclei to effect the reaction between (2) and the complex, and/or a scavenger to prevent reaction between (2) and oxidized (1). In a second embodiment (1) contains a dyemoiety and an anti-foggant moiety and reacts with the silver complex to form a non-diffusible product, and (2) reacts with either the exposed silver halide or undergoes a redox action with oxidized developing agent, to form an oxidation product which undergoes intramolecular ring- closure as described above. The dye-images formed from the diffusible materials may be of the same or complementary colours.

Abstract: 1,099,470. Refrigerators. CHEMETRON CORPORATION. May 26, 1965 [Oct. 27, 1964], No. 22421/65. Heading F4H. In a process for freezing a continuously moving product, a current of gaseous refrigerant is passed in heat transfer relation with liquid refrigerant to evaporate the latter, the thus evaporated refrigerant is mixed with the gaseous current and the combined stream is circulated over the product then re-cycled as said gaseous current. As shown, products on a perforate conveyer 22 are moved through a freezing tunnel having sections 10a, 10b and 10c, the section 10a housing a fixed cooling coil 40 which is supplied with liquid nitrogen by conduit 35 and has an open end 45a. A fan 50 circulates gaseous nitrogen over coil 40 and the evaporated nitrogen issuing from end 45a is combined with said gaseous nitrogen, the mixed stream being supplied to a plenum chamber 51. Cold gaseous nitrogen is discharged from the latter through downwardly directed nozzles 55 (Fig. 3, not shown) at speeds of up to 6000 or 7000 feet per minute. The build-up of pressure in section 10a causes gaseous nitrogen to flow up- and downstream of the conveyer through openings 18 and 19 respectively to the other sections in which the nitrogen is circulated by fan, plenum chamber and nozzle means similar to those in section 10a but without the cooling coil. The supply of liquid nitrogen to coil 40 is regulated by a valve 36 (Fig. 4, not shown) which is controlled by a device 42 responsive to the liquid level in coil 40 and by a device 49 responsive to the temperature in section 10a. The conveyer 22 may be imperforate or have a removable imperforate cover for use in freezing liquid products, additional upwardly discharging nozzles may be provided beneath the conveyer and the conveyer may be replaced by a fixed grid through which the gaseous nitrogen is forced upwardly and at an angle to fluidise and convey the product. Coil 40 may be replaced by means for spraying liquid nitrogen into the recirculating gaseous current. The product leaving the apparatus may be dried by allowing ice in the product to sublimate under vacuum.

Filed: 1948-08-27
Abstract: 640,799. Gas turbine plant for aircraft. BRITISH THOMSON-HOUSTON CO., Ltd., and FORSLING, B. E. G. Aug. 27, 1948, No. 22681. [Class 110(iii)] [Also in Group XXXIII] An auxiliary gas turbine plant for aircraft comprises a turbine 4 driving a compressor 3 and a turbine 7 driving a generator 8 and other auxiliaries. The compressor 3 supplies air for the combustion chambers 6, 24 of both turbines and for the aircraft cabin. Air for the cabin passes through a cooler 29. Valves 22, 23 regulate the flow of air to turbine 7 and the cabin. Fuel for the turbine 4 is regulated in response to the speed of turbine 7 and the pressure in the aircraft cabin. Fuel for the turbine 7 is regulated in response to the inlet or exhaust temperature of that turbine. The valves 22, 23 are automatically controlled so that a rise in air pressure causes the valve 22 to open and when that valve is fully open causes the valve 23 to shut. The turbine 4 may have oppositelyrotating rotors mounted on co-axial shafts and driving separate stages of the compressor. The air from the cabin may be evacuated to the combustion chamber 24; valves being provided to control the flow of air from the cabin to atmosphere and to the chamber 24. The air from the cabin may be led to a separate combustion chamber. In that case the latter chamber and the chamber 24 deliver working fluid to separate nozzle segments of the turbine 7 which exhaust to separate exhaust pipes. The exhausts of both turbines 4, 7 may be used in propulsion nozzles. In the plant, with a turbine 4 having oppositely-rotating rotors, the shafts are supported in a downstream bearing and the exhaust is divided into two separate pipes so as not to enclose the bearing.
