Title: Improvements in the manufacture and production of colour lakes
IPC: C09B69/06
Filed: 1926-03-29
Abstract: 265,032. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). March 29, 1926. Lakes containing complex tungstic acids are obtained by treating a basic dyestuff, which may or may not contain acid groups, with components capable of forming complex tungstic acids and other than those containing molybdenum, in the presence of an acid which does not take part in the reaction and which has a higher dissociation constant than tartaric acid. The components and the acid may be added in any order, or they may be mixed together and added to the solution of the dyestuff to precipitate the lake. The precipitation may take place in the presence or absence of a substratum. In an example, a substratum is made by mixing heavy spar with sodium sulphate solution and precipitating with barium chloride. Solutions of Methyl Violet B extra. sodium tungstate, and sodium phosphate are successively added to the substratum, and the lake is finally precipitated by adding hydrochloric acid and heating to 80‹ C.

Abstract: 1,096,608. Photographic films. INTERNATIONAL POLAROID CORPORATION. March 1, 1965, No. 8659/65. Addition to 1, 059, 850. Heading G2A. In a film assemblage for carrying out an image transfer process, the unexposed photo-sensitive sheet is stored in a container 32, and the imagereceiving sheet, which is impregnated with a strongly alkaline processing liquid, is stored in a second container 10. The latter must be impervious to the processing liquid, and must be sealed against the passage of liquid or gas until required for use. The peripheral wall 14 has a pair of lips 20 formed integrally therewith, on each side of a longitudinal slot 18, the lips being bonded together at their ends 24 so that the container is completely sealed. Between the lips is gripped the leading end 26 of the impregnated image-receiving sheet 12, the remainder being coiled up inside the container. Lips 20 lie in a recess between a corresponding pair of lips 40 formed on container 32 which holds the photo-sensitive image-recording sheet 30. The leading end of this, as it emerges from container 32, is secured to a connecting sheet 46, which is also connected to one of the lips 20. Sheet 46 passes round the outside of container 32, and under a retaining strap 48 holding the two containers together. The lips 20 have weakened narrow portions 44 where they join on to the container walls 14, which may be broken by flexing the lips back and forth, using the outer lips 40 as a tool. The containers are then separated and loaded into appropriate sections of a camera such as is disclosed in Specification 1, 059, 849. The two sheets are then drawn forward together by their coupled leading ends, and threaded between a pair of pressure rollers in preparation for making an exposure.

Title: Rotary internal combustion engine
IPC: F01C1/077
Filed: 1938-03-25
Abstract: 499,553. Rotary internal-combustion engines. McINTYRE, H. March 25, 1938. No. 9222. [Class 110 (ii)] The engine is of the geared-vane type comprising two discs 12, 13, each having four pistons 14 ... 17 and 18 ... 21 attached to their peripheries. A shaft 9 is driven by the discs 12, 13 through crank-pins 30 on cranks 31 having trunnions 33 supported in bearings 35. Pinions 36 are keyed to trunnions 33 and mesh with internal gears 44 which are secured in cylindrical recesses in fly-wheels 40. Bearings 43 are carried by cranks 46x. The cranks have each a shaft 46 carried by bearings 43, 41x. Gears 48 on the shafts 46 mesh with stationary racks 38, 39. The gear 48 and rack 38 have a gear ratio of four to one. The crank-pins 30 rotate in an anticlockwise direction around centres formed by trunnions 33 and the gears 36 travel around the internal gears 44 in a clockwise direction, held in mesh by crank arms 46x revolving in annular recesses 45. By this means the shafts 46 are rotated to rotate gears 48 meshing with racks 38, 39 and through the fly-wheels 40 driving the shaft 9 in an anticlockwise direction of rotation. Gears 36 and internal gears 44 have a gear ratio of one to two. The discs 12, 13 have slots 26, 27 and 28, 29, curving in opposite directions, the pins 30 moving along these curves to give the discs alternating fast and slow motions. Ports 23 act as both air inlet and exhaust ports. A part of the incoming air is deflected into an exhausting space for scavenging purposes. The air remains at atmospheric pressure while gratings 23, on each side of the annular cylinder are open to the annular cylinder. Fuel is injected through holes 24, 25, and is burnt due to the heat of the air compressed between a pair of pistons. While a working piston is being driven forward by the gases expanding to atmospheric pressure, the following pair of pistons containing a compressed charge move past holes 24 or 25. Figs. 1, 26 shows a form of fuel injector that may be used with the engine. A cam-shaft 50 is driven by the shaft 9 through gearing 51 ... 55. The cam 56 operates spring- pressed plungers 57 for forcing oil fed into a duct 57x through ports 58 as the cam releases each plunger. The oil pressure raises a needle valve 59 provided with spiral grooves 59x which impart a whirling motion to the oil as it passes through flared orifices 24, 25.
