Title: Photosensitive element with dye developer
IPC: G03C8/16
Filed: 1961-08-21
Abstract: 938,863. Photo-sensitive elements with dye developer. INTERNATIONAL POLAROID CORPORATION. Aug. 21, 1961 [Aug. 22, 1960], No. 30106/61. Class 98 (2). A support bears a silver halide emulsion layer with dye developer therein or available thereto and has an outermost alkali-permeable layer containing at least one silver halide developing agent. There may be red, green and blue sensitive emulsion layers each with the respective dye developer for cyan, magenta and yellow, and a product with such layer or layers may include a rupturable container holding at least an alkaline processing solution, and also an image-receiving layer for colour or multicolour image production by transfer of unoxidised dye developer after exposure and processing. The purpose of the silver halide developing agent is to initiate and possibly accelerate the action of dye developer, improve colour separation and reduce highlight stain. Example 1 describes an eleven layer element including various spacer and barrier layers and with the dye developers in layers adjacent to their emulsions, the outermost layer comprising cellulose acetate hydrogen phthalate containing 1 - phenyl - 3 - pyrazolidone and 2,5 - dihydroxy - p - benzene diacetic acid; and the transfer processing with this using alkaline sodium carboxymethyl cellulose and 5-nitrobenzimidazole to provide a multicolour image on a receiving layer. Examples 2, 3, 4 describe variations for such outermost layer and Example 5 a density comparison procedure. Other alkali-soluble hydroquinone type developers are listed. Specifications 684,591, 684,592, 804,972, 804,976, 853,478, 853,481, 938,864, 938,865, 938,866 and U.S.A. Specifications 2,289,367 and 2,731,300 are referred to.

Abstract: 1424741 Magnetic storage arrangements VYCHISLITELNY TSENTR SIBIRSKOGO OTDELENIYA AKADEMII NAUK SSSR 26 June 1973 30290/73 Heading H3B In a magnetic storage matrix assembling arrangement in which rows of apertured magnetic cores 2, Fig. 1, strung on parallel Y wires 1 are sequentially threaded by X wires 6 at a threading member 4, the matrix sense wires 8 are threaded through the cores at a core positioning mechanism 10 movably positioned between the X wire threading mechanism 4 and that part of the matrix already fully assembled. The core positioning mechanism includes tension devices 13 for the X wire or X wires of cores undergoing simultaneous threading by a sense wire, and also angularly positions the cores so that they present as large an effective aperture as possible to the offered sense wire. In a modification, Fig. 2, the cores to be threaded by a sense wire are located in a longitudinal slot 15 in a rotatable roll, two rolls of cores being accommodated at any time so that a single sense wire 8 may be threaded with centralized transposition between the rows. In a further modification, Fig. 3, the core positioning mechanism may be tilted with respect to the matrix co-ordinates so that the cores to be threaded are disposed at right angles to the offered sense wire. This embodiment includes threaded roll portions 19, 20, 21 independently rotatable by handles 22, and the grooves of which locate the Y wires into spaced groups 17 to facilitate internal transpositions between rows of a sense wire. In this case two sense wires 8 each allocated to one half of a completed matrix are threaded through the cores, the independently rotatable portions enable sense wire row tranpositions to be effected after straight line core threading operations. Fig. 4 shows an alternative arrangement for effecting spaced grouping of the Y wires, pegs 28 mounted on respective movable subframes 26, 27 being used to urge the Y wires together. In a modification, Fig. 5, the subframes are urged together by springs 29 the convolutions of which are used as Y wire guides.

Abstract: 1411284 Delivering measured quantities of liquid WILSON & SONS (ENG) Ltd 18 June 1973 [29 June 1972] 30444/72 Heading B8N A machine for dispensing different measured volumes of liquid comprises a chamber 10 having ari inlet 46 and an outlet 66 and which holds when full the largest of the volumes to be measured, a partition 18 within the chamber to provide a compartment B of a smaller volume to be measured, a passage 26 between the compartments A and B, and a valve 32 operable so that liquid from the whole chamber or the compartment B can be selectively dispensed through the outlet. The machine may be coinoperated and the partition made adjustable by means of lock nuts 22. When the larger volume is to be dispensed, the valve 32 is open as shown to allow the liquid to pass into both compartments A and B from the inlet 46. A float valve 56 at the air outlet serves to switch off the supply pump motor when the chamber is full. The solenoid-operated outlet diaphragm valve 68 is then opened to deliver the liquid. When the smaller volume of compartment B is to be dispensed the valve 32 is shut by a solenoid 44 during the filling operation and opened when the valve 68 is opened to deliver the liquid. The wall 12 of the chamber may be transparent. The machine could be modified to dispense more than one smaller volume by providing further partitions and associated valved passages, one or more of which could be opened during the filling operation.

Abstract: 941,615. Preheating processes for evaporator feed liquids. A.P.V. CO. Ltd. Aug. 25, 1961 [Sept. 7, 1960], No. 30829/60. Heading B1B. In a process for preheating the feed to an evaporator, at least a part of the vapour produced in the evaporator passes via duct 1 into the direct contact condenser 2, where it is condensed by contact with a spray of cold liquid issuing from the spray-head 3. The hot condensate thus obtained is circulated via line 4 through the heat exchanger 6, which may be of the plate-type, where it transfers heat to a countercurrent flow of feed to the evaporator. The cooled condensate returns to the condenser 2 via line 4 for further use as a cooling medium. Excess condensate is continually removed from condenser 2 by the outlet 8. Also described is a system using a number of evaporation stages, each stage being provided with a condenser circuit according to the invention, the feed to the first evaporator being passed through the individual heat-exchangers in series.

Class 110(2) A fluid turbine meter has a rotor with: concentric helical vanes,. an inner helix 7 of right handed pitch formed between a spindle 6 and a cylindrical sleeve 8 and an outer helix 9 of left handed pitch formed on the outside of the sleeve 8. Fluid from a conduit 13 enters a 'chamber 10, annular in part, which registers with theinner helix 7 up through which the fluid passes. when its direction is reversed by a chamber 11 so that it passes back down through the outer helix 9 which registers with a chamber 12, annular in part, and the fluid is discharged through a conduit 14. The effect of the fluid acting on the two helices is additive while a reduction of forces acting on the rotor is obtained. The shaft 5 operates an indicating mechanism. Damping baffles may be placed in the chamber 11 (see Fig. 4, not shown), or in other positions. Guide vanes may be placed below and/or above the rotor. The outer and inner helices may be of differeht pitch and different height or have a different number of blades and they may be conical. The case is also included when the pitch of the helices is infinite so that the blades are parallel to the axis of the rotor.
