Title: Improvements in or relating to colour photography
IPC: G03C7/04
Filed: 1928-02-20
Abstract: 317,712. Ruth, R. Feb. 20, 192R. Colour photography; multicolour screen processes.-For the production on an opaque support of a picture in natural colours to be viewed by reflected light a colour image is obtained from a gelatin screen layer by the action of reaction products produced in the photographic process. A transparent support with a detachable screen gelatin layer is coated with a non-detachable bromide emulsion layer and is exposed to a colour screen picture through the support. The exposed plate is developed with a developer (e.g. pyrocatechin) producing a high proportion of gelatinhardening oxidization products. If it is necessary to reverse the image the reduced silver is dissolved out and the remaining silver salt is exposed and developed with a non-hardening developer. The screen and image layers are transferred to a paper support which may be the final or a temporary support according to circumstances, this is effected by pressing the paper in soaked condition on to the image layer, allowing the combination to dry and drawing it together with the layers from the transparent support. The now uncovered screen laver is treated with hot water as in the carbon process. As an alternative the " ozobrome " process may be used in which the chemical effects taking place in the silver image have likewise a hardening action upon an adjacent layer of gelatin.

Title: Improvements in or relating to the lubrication of thrust bearings and slip ring seals
IPC: F16J15/40
Filed: 1960-02-17
Abstract: 899,663. Stuffing-box substitutes. FROLICH, B. Feb. 17, 1960 [Feb. 28, 1959], No. 5660/60. Class 122 (5). [Also in Group XXXIV] In a thrust bearing or slip ring seal, lubricant, e.g. water or oil is supplied between the rotating and fixed rings, the bearing face of the former having a ring or rings of recesses which cooperate with a groove or grooves in the fixed ring to increase the pressure of the lubricant. A rotating shaft 1 has secured thereto a disc 2, Figs. 1-3, having recesses 5 thereon, the disc engaging a ring 3 having a groove 6 with a lubricant inlet 7. The lubricant enters the inlet 7, is swirled around in the groove 6 by the rotation of the disc 2, thus increasing the pressure, and then penetrates between the bearing faces to lubricate and also take up the axial thrust on the bearing; several arrangements of grooves in the ring 3 are described, and the ring may be replaced by a segment. In a modification, Figs. 14, 15, the shaft 1 carries disc 2 spring urged against rings 3 integral with a journal bearing 11, and the sump 4 is filled to a point 12. Lubricant passes into the inlets 7, through the grooves 6, and a portion of the lubricant passes through grooves 13 to lubricate the journal. If the pressure between the faces increases too much the discs 2 are moved axially against the springs and the lubricant flows more easily. In a further modification, Figs. 23, 24, the groove 6 in the ring 3 has an inlet and discharge 7, 9 at each end which are controlled by balls 25, 24. When the disc 2 rotates in one direction one of the balls 25 is lifted from its seat and the ball 24 at the opposite end of the groove 6 allows the lubricant to flow as shown by arrows in Fig. 24. If disc 2 rotates in the opposite direction the opposite balls 24, 25 open and the previous mentioned balls close their respective passages to allow a reverse flow of lubricant. A slip ring seal for a rotary pump, Figs. 19-22, comprises a ring 2 having cells 5 and a lubricant collecting chamber 22, the ring being spring urged against a stationary ring 3 carried by a shaft 1 to form a seal. Ring 3 has a lubricant groove 6 and a lubricant collecting chamber 27 and the lubricant pressure is increased in groove 6 by rotation of ring 2.
