Filed: 1940-02-05
Abstract: 539,391. Colour photography. KODAK, Ltd. (Eastman Kodak Co.). Feb. 5, 1940, No. 2201. [Class 98 (ii)] In the production of colour photographs from multilayer material by the dye-destruction process, balance as regards contrast is obtained by the incorporation in one or more lightsensitive layers, which contain an imageforming dye or dye-forming substance, of an auxiliary dye absorbing light by which the layer containing it is intended to be exposed, and removing the auxiliary dye after exposure. The auxiliary dye is preferably soluble in water or sodium carbonate solution, and may have a tendency to diffuse and should not be bleached image-wise. In three-layer material in which at least two emulsion layers contain imageforming dyes, auxiliary dyes are preferably, but not necessarily, employed in each imagedye-containing layer. The auxiliary dye is preferably of a colour complementary to the layer-sensitivity. The material may be a threelayer or a two-layer mixed grain material. The image-forming dye may be added as such or in its leuco form, the dye being then produced before or after exposure. The dye-destruction bath may comprise thiourea, sulphuric acid, and potassium bromide or may be alkaline stannous chloride. In an example, the material comprises a support carrying in superposition an infra-red sensitized emulsion containing a magenta image dye and a blue-green auxiliary dye, a green-sensitized emulsion containing a yellow image dye and a magenta auxiliary dye, and a blue-sensitive emulsion containing a blue-green image dye and a yellow auxiliary dye. The infra-red sensitizer may be kryptocyanine and the green-sensitizer pinaflavol. The material is exposed through the bluesensitive layer. Auxiliary dyes referred to are Tartrazine, Chromotrop BB, Alizarin Celestol, and Brilliant Paper Yellow. Specifications 133,034, [Class 98 (ii)], 468,560, 477,524, 503,752, 521,746, 521,833, 521,834, 521,835, 521,836, 521,837 and 521,888 are referred to.

Title: A tool for exerting a force upon a workpiece
IPC: H05K13/04
Filed: 1967-01-19
Abstract: 1,107,119. Riveting. AMP Inc. 19 Jan., 1967 [10 Feb., 1966], No. 2785/67. Heading B3U. A staking tool comprises a tool body, a tool head movable relative to the tool body against a first spring to cause the tool head to apply a first force to the workpiece, a force applying member acting through a second spring to cause the tool head to move further relative to the body to apply a second force to the workpiece and sensing means responsive to the relative movement between the tool head and the tool body to render the force applying member inoperative upon the first and second forces reaching a predetermined aggregate value. The tool is used to insert stakes 84 into eyelets 82 in an insulating panel 80 to trap electrical heads (not shown) between the stakes and the eyelets. A base 10 and column 12 support a bracket 14 on which is mounted an air cylinder 16, the piston rod 22 of which is connected to a tool body 24. A plunger 54 is slidable inside the tool body 24 and is biased downwardly by a spring 58. An extension 28 of the tool body 24 guides a carrier 42 on which the staking head 52 is mounted. The staking head is downwardly biased by a spring 48 between the upper end of the carrier and a capnut 38 which screws into the extension 28. A rod 46 projecting upwardly from the carrier 42 completely fills a corresponding bore in the plunger 54 when the spring 48 is compressed as shown in Fig. 4. When there is no obstruction to its movement the carrier 42 is moved downwardly by the spring 48 until collar 44 abuts the shoulder 50. A micro-switch 64 is fixed to the tool body 24 and a switch-operating rod is carried by a lifting hook 66 attached to the carrier 42. Operation.-The hook 66 is lifted and the panel 80 moved to bring a stake 84 under the staking head 52. When the hook is released the spring moves the head 52 on to the stake with a force of up to 2 1bs. The air cylinder is then operated to move the entire tool body downwardly. If the spring 48 is not fully compressed then the carrier moves up into the extension 28, the spring 48 compressing until the rod 46 bottoms in its bore. At this point there is a gap " X " between the rod 68 and the micro-switch 64. Further movement of the piston-rod 22 causes the plunger 54 to move against the spring 58, until the rod 68 operates the micro-switch 64. The force necessary to deflect the spring 58 by the amount " X " is 10 lbs., so that the total force on the staking head 52 is 12 1bs.
