Title: An improved process for preparing chromate colloid images from photographic silver images
IPC: G03C5/50
Filed: 1940-03-19
Abstract: 539,799. Photographic gelatin layers. STEIN, O. March 19, 1940, No. 5116. [Class 98 (ii)] A gelatin layer is cast by coating a support at room temperature (10-20‹C. ) with an aqueous gelatin solution containing a substance which so reduces the setting point of the solution that it is liquid at room temperature, and thereafter treating the liquid layer to remove the effect of the substance so that the layer sets. Substances which may be so used are potassium or sodium nitrate, calcium barium or magnesium chloride, potassium iodide, a soluble thiocyanate, sodium salicylate, the sodium salt of α-naphthalene sulphonic acid, urea, and chloral hydrate. The effect may be removed in some cases by immersing the liquid layer carefully in cold water which dissolves out the substance, and in others by treatment with a cold chemical bath which converts the substance into another which does not possess the property of lowering the setting point e.g. barium chloride may be precipitated as barium sulphate. The method may be used for coating a gelatin layer on a photographic silver image layer prior to known treatment with a bath (e.g. containing potassium bichromate, sodium chloride, and cupric chloride) which hardens the coated gelatin where silver is present. The coated gelatin layer may contain dye or pigment so that a coloured relief image may be produced by washing away the unhardened gelatin with warm water and then fixing out the silver image. If the gelatin layer is uncoloured, it may be differentially dyed after the hardening step, or converted to a wash-out relief. The contrast of the image may be varied by regulating the proportion of bichromate in the hardening bath, or by local variation of temperature of the washing-out water. The removal of the effect of the substance may be performed by the water of the bleaching bath, or by including therein a precipitating salt (e.g. replacing the cupric chloride by cupric sulphate).

Title: Method and device for separation of substances by extraction
IPC: B01D11/02
Filed: 1946-02-19
Abstract: 614,333. Making extracts. STAVANGER ELECTRO - STAALVERK AKTIESELSKAPET. Feb. 19, 1946. No. 5144. Convention date, Aug. 21, 1944. [Class 81 (i)] [Also i Group II] In a method of separating substances by solvent extraction wherein the extracted substance is separated by lowering the temperature of the solution to below that at which the extracted substance is soluble and wherein the process is continuous, the difference in temperature between the different parts of the solvent is used to produce a circulation of the solvent. As shown, applied to the extraction of one metal from a mixture of metals, a container A holding a molten mixture of manganese, iron and carbon is treated with molten bismuth in which manganese alone is soluble. The solution of manganese in bismuth separates on the surface and is drawn off along a pipe 1, which may be artificially cooled, to a container B at a lower temperature when the manganese separates and may be removed from the surface. The bismuth flows through a descending tube 2 and a heater 3 on a rising arm produces a thermosyphon effect to return the bismuth to the container A. The parts of the apparatus may be maintained at the temperatures most suitable for the process.

Title: Improvements in or relating to the preparation of record cards for use in controlling business machines
IPC: G03D15/10
Filed: 1947-02-21
Abstract: 627,890. Making record cards. REMINGTON RAND, Inc. Feb. 21, 1947, No. 5158. Conventon date, March 4, 1946. [Class 73] [Also in Groups XIX and XX] A machine for applying photographic film to record cards has two stations ; one applies a slightly tacky adhesive tape to the sides of an aperture in the card so as to cover the aperture and the other cuts and presses the film into place on the exposed portion of the tape within the aperture. These two processes are not carried out in direct sequence, but cards first pass through the initial stage, are inverted, and when the correct film frame has been chosen by means of a projector, the card is passed through the machine again to receive it. The machine is driven by a splined central shaft which drives two main shafts 50, 60, Figs. 6 and 7, and feed rollers 35, 36, 37, 38, 40, 41, 42, 43. The cards are stacked at 12 and are fed in 'turn between rollers 35, 36, by a carrier 54 reciprocated by means of a cam 46 on shaft 50. On leaving rollers 35, 36, the card is fed between plates 55, 56 by rollers 37 and stopped in this position by stops 58. A transparent adhesive tape 70 is fed from a reel 67, past a device for stripping from it a tissue' protecting strip 111, and under a stamping and applying die 127, Fig. 11, and a piece of tape is pressed into place over the aperture in the card by the die 127 operated by the link 136 and cam 138 on shaft 50. Stops 58 are then lowered by cam 61 on shaft 50 and the card is ejected from the machine by rollers 38, 42. The taped cards are inverted and restacked at 12 and the machine set for single cycle operation. Steps 58 are lowered by means of links 143, 144, 145 and latch 147 which projects from the front of the machine. A similar latch 154 brings card stops 155, Fig. 7, of the film applying stage into operative position, the drive on the adhesive tape is then disconnected. The photographic film 230, Fig. 5, is mounted on a reel 170 and is fed through a projector 178 under a stamping press, similar to that for applying the adhesive tape, and back to a reel 171. The film is first fed by a hand wheel until the operator sees the desired frame in the projector. He then connects the film drive to the main shaft and presses the start button and the required frame is drawn under the stamping and applying press and applied to the card in the recess formed by the hole in the card and the adhesive tape. The stops 155 are then withdrawn by cam 264, and the completed card is ejected. The film is then returned so that the cut out portion is returned to the projector and the machine then stops. The operator then chooses the film for the next card. A modification is described in which continuous feeding of film 230 is obtained. Specification 510,910, [Group VIII], and U.S.A. Specifications 1,476,161, 1,780,621 and 2,044,119 are referred to.

Abstract: 414,443. Grinding valves. KLEIN, O., 83, Uhlbacherstrasse, Obert³rkheim, Stuttgart, Germany. Feb. 20, 1933, No. 5212. [Class 60.] In a machine for grinding the seating surface of mushroom type valves, the grinding-wheel rotates on a stationary axis, and the valve is rotated and at the same time reciprocated to carry its seating surface across the operative surface of the grinding-wheel. The machine, Figs. 1, 3 and 4, comprises a grinding-wheel 3 mounted on a spindle 2 in a base 1, a second grinding-wheel also being mounted on the spindle for hand grinding of tools &c. The spindle 2 drives a shaft 4 which drives, through worm gearing 10, a vertical shaft 9 having at its lower end an eccentric pin 11 engaging a guide block 12 guided in a transverse slot 13 in a guide bar 7, thereby causing reciprocation of a valve head carrier 6 on a guide bar 8 and the bar 7. The shaft 9 also drives, through gearing 14, 15, a shaft 16 driving, through wormgearing 17, a valve holder 18 mounted in a casing 20, which is adjustable angularly, to suit the bevel of the valve, on a sleeve 19; in order that adjustment of the valve relatively to the grinding-wheel may not alter the angular setting of the valve, the sleeve 19 is rotatable in a part 22 of the carrier 6 and carries a gear 25 meshing through an idler gear 24, with a gear 23 keyed to a pin 21 coaxial with the shaft 9, the part 22 being moved about the pin 21 to adjust the position of the valve. The valve also may be adjusted parallel to the axis of the grinding-wheel by adjustment of the bar 7 by means of a screw 26, or by means of a screw-engaging the bar 7. In a modification, the valve holder is rotated by a flexible shaft, similar means to that described above being used to reciprocate the valve, and to adjust the holder parallel to the axis of the grinding-wheel. In a further modification, the grinding-wheel is adjustable transversely, and the valve driving mechanism comprises an electric motor driving the valve and, through gearing, operating the shaft to cause reciprocation of the valve ; the means for adjusting the valve parallel to the axis of the grinding-wheel is similar to that described above.
