Title: Improvements relating to photographic diffusion transfer processes
IPC: C09B43/132
Filed: 1958-05-09
Abstract: 879,171. Photographic diffusion-transfer processes. INTERNATIONAL POLAROID CORPORATION. May 9, 1958 [June 5, 1957], No. 14950/58. Drawings to Specification. Class 98(2) Monochrome and multicolour image transfer from an exposed light-sensitive layer or layers to a receiving layer is effected with aid of at least two processing liquids, one of which is applied between transfer surfaces, as from a container carried by one of these, and another of which is applied externally, normally to penetrate a layer support before attaining operative position. For silver image transfer a container is preferably attached to the receiving layer, and drawings (not shown) illustrate a camera with accommodation for roll films having areas respectively for latent and transfer. images, and containers appropriately carried so that passage of the superimposed layers through pressure rollers after exposure will release liquid for some stage of processing, after which a door in the camera may be opened and a second liquid applied by an applicator swab to the support side of the receiving layer; subsequent withdrawal from the camera and separation of the layers enables viewing of the festive transfer image. The second processing liquid may, however, be applied as by immersion outside the camera. A reversal developer mixing is quoted for the first of these liquids and a stabilizer for the second, this consisting of 1 % of gold chloride in equal parts of water and methyl alcohol. For colour image transfer a sensitive layer of screen formation may be used, but preferably there are several sensitive layers containing colour providing substances in the sequence of normal subtractive multilayer film, and a processing-liquid container may be attached to the immediate side of the transfer material or to both sides, in which case a further layer is present to facilitate spreading of the liquid, and in both of which cases liquid may be also applied externally so that either two or three successive processings may be effected. Application of liquid from a container introduced into the bite of pressure rollers or introduced in other manners is referred to also. The colour providing substances and processing liquids therefor are such as to release colour for transfer at some stage of the process, thus reducible dyes, coupling dyes, metallic complexes of dyes, colour couplers, colour formers which are esters for hydrolysation, couplers for treatment with diazonium salts, dye developers and other materials for use in the layers are mentioned, with references to other Specifications such as Specifications 853,478 and 853,480 for definite disclosures; and developing agents, thiosulphates, alkalis, reducing agents and oxidizing agents are mentioned for inclusion in one or other of the liquids for action on these colour providing substances. Specifications 684,592, 732,420 and 804,976 also are referred to.

Title: Method of and apparatus for volatilizing and oxidizing minerals
IPC: C22B4/00
Filed: 1923-06-11
Abstract: 223,271. Marks, E. C. R., (Cobb Electro Reduction Corporation of Canada, Ltd.). June 11, 1923. Arsenic, antimony, cobalt, molybdenum, tin, vanadium, zinc, and other metallic oxides.-Volatilizable oxides are obtained from ores by feeding the finely divided material into an oxidizing zone above a bath, which may be maintained in fusion by means of electrodes immersed in the bath. The invention is described with reference to the treatment of molybdenite. An electric furnace 1 has electrodes 6, 7, 11, tap holes 4, 5, an air inlet 12 with a cock 13, a charging shaft 14, and fume outlet 15 leading to a bag house or condenser 16. To start the operation, a flux such as fluorspar coke and old silica slag is spread upon the bottom of the apparatus so as to cover the electrode 6 and the electrode 7 is lowered to fuse the flux. Finely divided slag is then added and the electrode 7 is gradually raised and is removed altogether when the bath reaches the level 5. The bath is maintained molten by current between the electrodes 6 and 11 and finely divided molybdenite is fed in through the shaft 14 into the airspace above the bath. Alternatively, the electrode 7 may be omitted, the fused bath being built up by means of external heating until the electrodes 11 are submerged, or the material may be fused in a separate apparatus. Additional electrodes 17 may be employed, Fig. 3, being arranged at a greater distance from the electrode than they are from each other so that they will remain in the circuit 18 and not be influenced by the current in the circuit 19. In another modification, Fig. 4, electrodes 20, 21, 22 correspond with the electrodes 6, 7, 11, Fig. 1. A doublethrow switch 23 is arranged so that one side closes contacts 24<a>, 24<b> with the 2-phase mains 23a in a circuit 24 which includes the electrodes 20, 21 and the other side closes contacts 25<a>, 25<b>, 25<c> with the 3-phase mains 23b in a circuit 25 which includes the electrodes 20, 22.

Abstract: 359,444. Actuating controllers; control of D.C. motors. COMPAGNIE GENERALE FRANÃAISE DE TRAMWAYS, 3, Rue Moncey, Paris. May 17, 1930, No. 15252. Convention date, June 5, 1929. [Class 38 (iii).] Regenerative and non-regenerative braking; armature control.-In a series-parallel control system for compound wound vehicle motors allowing for electric regeneration by means of adjustable resistances in the shunt field circuit, the shunt field and series field windings are constantly connected in the same way with their respective motors. Motors M, M<1> are controlled by one of two controllers C, C<1> to which are connected shunt field resistances R, armature resistance D and a resistance 0 for use at the change from series to parallel running. On the shaft 1 of the controller, Fig. 5, is a grooved pulley 7 on which is fitted a friction collar 8 having a stop 9 and a contact 10 connected with the main circuit-breaker. The shaft 1 in addition carries a cam 12 with which a spring-biased pivoted lever 15 co-operates so that if the controller is moved back-. ward from any position between the " off " and the series running position, the contact 10 is opened, but if the controller is moved backward from any of the parallel positions the stop 9 is engaged by the lever 15 and the opening of the contact 10 is prevented. A controller sector 5, Fig. 2, is con. nected with the shaft 1 by a lost motion connection comprising a pin 4 working in a slot in the sector, so that the controller is moved to the full series position without affecting the sector 5 but thereafter operates the sector to insert the resistance 0 between the motor armatures at the transition stage between series and parallel running. If at any time the speed of the motors exceeds the normal speed, the motors are regeneratively braked, and if for any reason the regenerated voltage exceeds a safe limit a relay U, Fig. 1, is actuated to open the main circuit breaker and by means of an auxiliary switch K to connect the motors to a braking resistance A.
