Title: The production of photographic images making use of the intensity-reversal effect
IPC: G03F5/24
Filed: 1959-03-11
Abstract: 882,690. Photographic materials and processes. EGGERT, J. March 11, 1959 [March 11, 1958(3)], No. 8418/59. Class 98(2). A photographic silver halide emulsion containing silver iodide and which has been subjected to physical ripening in the presence of an inhibitor but which has not received chemical ripening, is given a flash exposure of maximum duration 10<SP>-2</SP> secs., and then an imagewise exposure of lower intensity than the flash exposure. By making the flash exposure uniform, a reversal effect is obtained. The flash exposure may be a single exposure or a number of flash exposures of lower intensity. It may be given before the emulsion is cast on its support. Alternatively, the flash exposure may be given through a screen. Compensated prints may be made according to the invention from negatives having a large density range by making the flash exposure a sharp imagewise exposure and then giving an outof-focus exposure of lower intensity, for example by covering the printing paper with a sheet of opal glass. In this embodiment, the procedure may be modified by giving the outof-focus, low intensity exposure first, and then the sharp flash exposure. The emulsion is prepared by precipitating the silver halides at 40- 90‹C. in a protective colloid such as gelatin, preferably in the presence of excess watersoluble bromide, and then physically ripening the emulsion in the presence of an inhibitor or stabilizer such as a 1;3;4-triazaindolizine, a benzotriazole, hystidine, 2-ethyl benzoxazole, N-ethyl pyrrole or 2;3-dimethyl quinoxaline. The emulsion is then washed, but not subjected to chemical ripening. The emulsion or developer may contain thallium salts such as the nitrate. Specifications 619,557 628,994, 636,144 and 636,145 are referred to.

Title: Improvements in and relating to the production of asbestos
IPC: B07B13/00
Filed: 1932-03-22
Abstract: 385,803. Separating solid materials. BRODSKY, M. P., Asbestos Mines, Bajenoff, Ural, U.S.S.R. March 22, 1932, No. 8549. [Class 117.] Apparatus for separating asbestos fibre from the crushed rock containing it comprises an horizontal screen which is reciprocated up and down at an angle, the upward movement being suddenly stopped to throw the material against inclined surfaces. whereby the rock is deflected sideways and ultimately off the screen, whereas the asbestos is not deflected but merely progresses along the screen. As shown in Figs. 1 and 2, a screen A is mounted on swinging arms C which in the raised position are inclined at 45‹. The screen is depressed by a cam on a rotating shaft and is raised by springs D, the upward movement being arrested suddenly by stops. Above the screen are a series of pairs of inclined plates O. The material thrown upwards and forwards impinges against these plates, the rock thereby being deflected sideways while the asbestos progresses along the screen. Dust falls through the screen. In a modification Fig. 4, inclined plates O, P extend the whole length of the screen. The side plates P deflect the rock fragments towards the centre of the screen, and they are then thrown out by the centre plates O.

Abstract: 1,213,161. Hydrocarbon conversion catalysts. IMPERIAL CHEMICAL INDUSTRIES Ltd. 22 Feb., 1968 [23 Feb., 1967], No. 8735/67. Heading B1E. [Also in Division C5] A method of starting up a process for steam reforming hydrocarbons over a catalyst containing alkali metal compounds in which appreciable volatalisation of alkali normally occurs during the process, comprises heating the catalyst in a steam reforming plant at a temperature, e.g. 650‹ to 800‹C., at which combination of the compound with catalyst support material occurs to form "complexes" for a time, e.g. 24 hours, sufficient to ensure substantial combination. If steam is present at a partial pressure high enough to cause hydrolysis and breaking up of such complexes to the original compounds, initial heating, e.g. through the range 250‹ to 500‹C. should be rapid, e.g. 50‹C. per hour, but steam is prefera'bly either absent (e.g. it may be replaced by nitrogen), or at a partial pressure below that at which hydrolysis of the complexes occurs at the temperatures involved in starting up. The method is additional to normal catalyst activation with steam and hydrogen. Shutting down procedure is the reverse of starting up.

Abstract: 879,546. Grinding. NEIDL, G. March 19, 1958 [April 11, 1957: Dec. 13, 1957]. Class 59 [Also in Group XXVI] A pump impeller is formed as a disc which, when viewed in a direction vertical to the surface thereof or a chordal plane thereto, is of circular or substantially circular or elliptical shape and inclined to the axis of the shaft, the shaft being coaial with the cylindrical casing of the pump, and the impeller has teeth or the like on its periphery which engage in grooves at the inner periphery of the casing, whereby material, such as rags or sugar beet, contained in the fluid being pumped is disintegrated. The impeller shown in Fig. 7 comprises an elliptical disc 24 cut away at opposite ends to provide flat surfaces 30. The impeller is inclined to the shaft 43, Fig 6, the surfaces 30 having a small clearance or a sealing contact with end surfaces of the cylindrical pump casing. Teeth on the impeller engage corresponding peripheral grooves formed in a casing liner 45. The grooves are interrupted by a discharge port 36. Preferably, the left-hand surface 30 encircles the internal periphery of the suction branch 44 without crossing it. Rags contained in the water being pumped are torn up by the teeth and grooves. The teeth may have flattened tips, the grooves being correspondingly formed, and there may be considerable clearance between them if, say, slices of sugar beet are to be pumped, to prevent excessive disintegration of the beet. The impeller may be perforated to reduce side thrust. In a modification, the impeller disc is of fully elliptical form without cut-away surfaces 30, and with teeth over its entire periphery, and in this case it is disposed at a greater angle to the shaft to avoid contact with the casing end surfaces. Two impeller discs, intersecting each other at right angles, may be provided. Instead of being flat, the impeller disc may be curved. Specification 848,757 is referred to.

Class 39(i) An electron discharge tube for television comprises a storage electrode in the form of a layer with a high lateral resistance on one side of which high velocity electrons are incident such that their distribution over the layer corresponds with the light and shade of a picture, a charge image being built up on the other side of the layer by secondary electrons liberated on the said other side by the high velocity electrons. In Fig. 1 in a pickup tube electrons from a photo cathode 4 fall on a storage electrode 1 comprising an electron-permeable foil or film 2 of aluminium beryllium or magnesium provided with a thin coating 3 of magnesia or equivalent oxide into which the high velocity photo electrons penetrate liberating secondary electrons. The target is scanned by a beam 5 of about 1000 volts velocity to give signals in a device connected to the film 2. In the receiver tube of Fig. 2 the metallic film carries a very thin layer 7 of antimony activated e.g. by caesium vapour, to give strong photo electric emission. Insulating particles 3 e.g., of aluminium oxide or magnesium oxide are deposited on the layer 7 separated sufficiently so as to allow the antimony layer to be illuminated to release photo electrons. A beam 5<SP>1</SP> modulated in accordance with the light and shade of a picture scans the metal film of the storage target penetrating to the particles 3<SP>1</SP> and setting up a charge pattern. Flooding light from a source 10 liberates electrons from the photo cathode 7 the emission being controlled by the charge image on the particles 3<SP>1</SP>. The photo electrons are accelerated by electrode 9 on to the fluorescent screen 8.
