Title: Improvements in colour photographic materials
IPC: G03C7/388
Filed: 1939-01-23
Abstract: 524,554. Colour photography. KODAK, Ltd. (Eastman Kodak Co.). Jan. 23, 1939, No. 10139/40 Divided out of 524,154. [Class 98 (ii)] In colour photographic material having a plurality of differentially colour-sensitive emulsions on one or more supports, at least one of the emulsions consists of silver halide emulsified in a water soluble binder such as gelatine or agaragar having distributed through it fine discrete particles of a water-insoluble water-permeable binder, particularly a resin such as gum mastic, gum dammer, gum sandarach, gum elemi, polystryene, polymethyl methacrylate, polyvinyl acetate or coumarone-indene resin, containing a colour coupler. In material with a single support, all the emulsions on that side of the support on which more than one emulsion is located contain the particles. In multilayer' single support material, at least one of two adjacent layers contains the particles. At least one layer may be an emulsion of silver halide in a water-insoluble water-permeable binder containing a colour coupler such as is described in Specification 524,154. A layer of water-soluble binder containing particles of gelatino-silverhalide emulsion containing the colour coupler and any sensitizer required within an envelope of the water-insoluble water-permeable binder may be employed. A transparent or opaque support of cellulose nitrate or acetate, or paper may be employed. The processing baths may contain organic liquids or wetting agents to facilitate penetration. The resin may contain porosity modifiers such as plasticizers, or if necessary porosity may be decreased by hardening with chromium salts. Numerous colour couplers such as are described in Specification 524,154 are referred to. The colour produced need not be complementary to the sensitivity. Light-scatter may be reduced, volatile water-miscible organic solvents removed, and dispersions formed with the use of dispersing agents as described in Specification 524,154. The particles may be pre-formed. The silver halide employed may be silver bromide, chloride, or chlorobromide. Acid sensitizing dyes are preferable. A sound record may be recorded in one or more of the picture emulsions or in a separate emulsion. Antihalation and filter layers may be provided. The preparation of two and three layer material is described. Instead of using a yellow filter layer, the material may be dyed yellow throughout. The material may be colour developed directly or after rehalogenization or reversal. Specifications 440,032, 447,748, 458,664, 458,665, 474,353, 475,784, 475,786, 478,933, 478,934, 478,942, 478,952, 478,983, 478,984, 478,985, 478,986, 478,989, 478,990, 478,991, 493,952, 496,196, 496,245, 505,834, 509,707, and 524,555 also are referred to.

Title: Method and means for controlling the operation of steam engines
IPC: F01B31/12
Filed: 1931-04-07
Abstract: 376,742. Indicating apparatus in connection with controlling. CARACRISTI, V. Z., 3, Beechwood Road, Bronxville, New York, U.S.A. April 7, 1931, No. 10226. Convention date, April 4, 1930. [Class 79 (v).] Comprises a method and means for controlling the operation of a steam engine whereby the piston speed and steam pressure as influenced by boiler capacity and the resultant driving torque are automatically correlated to affect an indicator which is also affected by the manual control of the throttle or cut-off and enables the driver to obtain the maximum torque and horse-power and desired economy. The rod 10 is connected to the reversing lever controlling the cut-off ; the pivot 13 is connected to a lever 20 one end of which is subject to valve-chest pressure in a chamber 15, and the other end engages a cam 22 designed in conformity with a torque curve for saturated or superheated steam and which is operatively connected to a piston-speed indicator. The indicator has a speed-indicating hand 26, a dial 25 graduated in miles, and a horse-power indicating hand 27 on the same shaft as the hand 26 co-operating with a dial 28 graduated in terms of percentages of maximum horsepower output. The hand 26 points to the 100 per cent position with the production of maximum cylinder horse-power at any piston speed. The hand 27 operates a pinion and rack 30 connected to a marker 33 engaging a tape on a rotating drum. The speed hand 26 operates a marker 35, and the piston in chamber 15 actuates a marker 38. A change from ideal working conditions affects the hand 27, a plus movement indicates too late a cut-off, a drain on the boiler capacity, waste of steam and fuel. The indicator is maintained at the lowest possible minus point for a particular speed with full throttle. If maximum draw-bar horsepower is required, the cut-off is lengthened until the hand 27 points to the 100 per cent position. Variations in horse-power output and steam-chest pressure in relation to different engine-piston speeds are registered on the tape. The hands 26, 27 and their dials may be assembled in separate instruments.

As a wedge-shaped article 11, Fig. 3, is pushed, thick end first, into a pocket 17, 26 entraining a wrapping web 55, the upper wall 26 of the pocket is progressively lowered on to the article. In the form illustrated the article pushes inwardly a plunger 31 guided by a friction bush 33, and a roller 28 carried by the plunger allows the upper wall 26 to be pivoted downwardly by springs 27. The plunger also carries a guide 56 for the wrapping web 55. Fixed guides 57 form side-tucks. As the article, which may be a portion of cheese, approaches the end of its travel into the pocket, the web 55 is cut off and a vertically reciprocating folder 51 folds the severed web over the thin end of the article and pushes it into a gripper 36 carried by the pocket. The pocket then moves vertically downwards to register with a folding channel 58 into which it is pushed by the plunger 31 thus folding the wrapper under the bottom of the article at the same time as fixed tuckers 59 form sidetucks. The tucks are subsequently folded down by inclined surfaces 61, Fig. 1, on the channels 58 and the wrapped article finally passes to a heat-sealing device 62. The article is conveyed to the machine illustrated by a pusher conveyer 13, 14 extending at right angles to the pocket 17, 26.
