IPC: B01J8/20
Filed: 1932-12-02
Abstract: In a process for cracking hydrocarbon oils of the kind in which the oil in the presence of a finely divided catalyst is flowed continuously through a preheater and a reaction chamber heated to 400--600 DEG  C, part of the catalyst is added, preferably in batches, to the oil after it has been heated to reaction temperature at several successive places following each other in the direction of the flow of the oil, and the vapours formed and the liquid reaction products containing catalysts suspended therein are removed continuously from the reaction vessel.  The metals or their compounds of Groups 2--8 of the periodic system may be used as catalysts advantageous compounds being oxides, halides or acid salts, and active silica, carbon, kieselguhr, coke, &c., may be impregnated with the catalytic substances.  Catalysts also may be used which decompose during the reaction, e.g. carbonyls, oxalates, or organic halogen compounds.  The catalyst may be supplied to the reaction vessel by tubes of different lengths, made into a paste with oil free from asphalt, and may be added at places having different temperatures or different catalysts may be added at different places.  Pressures up to 100 atmospheres or over may be used or atmospheric pressure in which case hydrogen may be present.  An oil fraction boiling above 325 DEG  C. is heated to 485 DEG  C. in a gas heated tube system the pressure rising to 50 atmospheres.  As soon as the oil has reached a temperature of 420 DEG  C. 0,5 per cent by weight of the oil of a catalyst consisting of active carbon impregnated with zinc chloride is added at different places in the tube system and when the oil has attained 485 DEG  C. a further 0,5 per cent of catalyst is added and the oil passed into a cracking chamber of greater cross section.  A yield of 45 per cent benzine is obtained.

Abstract: 600,440. Optical pyrometers. HITCHMAN, D. G. I., and SCHOFIELD, F. H. Dec. 18, 1945, No. 34350. [Class 97 (iii)] In an optical pyrometer in which the brightness of the object is reduced to that of a filament of constant brightness by a graded optical wedge, the object is matched with two different colour filters in the eyepiece and temperature scales are provided to indicate directly the brightness temperatures for the two wave-lengths and the colour temperature (i.e. the temperature of a black body having the same ratio of brightness in the two wavelengths as that of the object). The wedges used are such that the logarithm of the transmission is directly proportional to the distance from one end of the wedge. As shown in Fig. 2 a wedge W and a slide C are moved together to match the object when a red filter is in the eyepiece whilst the wedge W is moved alone when the red filter has been replaced by a blue filter. The brightness temperatures for the red and blue wave-lengths are indicated by a scale R on the slide C and a scale B on the wedge respectively. The colour temperature is indicated by an index mark on the wedge W reading against a second scale on the slide C. In a modification the eyepiece is adapted to produce two images, one through a red filter and the other through a blue. Two wedges are provided, one in the optical path of each image, and are graduated in a manner similar to that of the wedge W and slide C of Fig. 2. As shown in Fig. 8, the wedges WB and WR are attached to flanges on the rotatable end walls C, A, of the cylindrical instrument casing T. The flanges carry the scales B, R, whilst the colour temperature is indicated by a scale on the end wall C co-operating with a pointer P on a spindle S fixed to the end wall A.

Title: Improvements relating to sheet transfer apparatus
Inventor: VOYSEY RONALD GEORGE
IPC: B31B19/02
Filed: 1954-12-01
Abstract: 796,687. Sheet feeding and delivery apparatus. CARMICHAEL & CO., Ltd., P. Nov. 30, 1955 [Dec. 1, 1954], No. 34831/54. Classes 100(1) and 100(2). Sheet transfer apparatus for use in printing, folding, envelope-making &c. apparatus comprises a series of suction cylinders each connected to a suction main, a trigger valve in each suction connection except that to the first cylinder, and each valve is adapted to be opened in response to a decrease in pressure inside one of the preceding cylinders when a sheet is held on that cylinder. As shown, sheets B separated from a pile W are transferred by suction cylinders 1-5 through a machine, the interior of each cylinder being connected to a main pipe 7 communicating with a vacuum pump. The cylinder 1 is connected to the pipe 7 by a pipe 8, a regulator valve 9, and a fixed manifold 6; the cylinder 2 is connected to the pipe 7 by a pipe 10, a trigger valve 12, and fixed manifold 11: and the other cylinders are connected to the pipe 7 through an arrangement similar to that for the cylinder 2. The trigger valve 12 has a piston valve 12a which is urged by gravity or a light spring to closed position, and the casing is connected to the interior of the cylinder 1: by this arrangement, unless there is a sheet B on the cylinder 1 closing the orifices o therein and causing a decrease in pressure in the interior of the cylinder 1, the valve 12 will not be opened, and the cylinder 2 will not be connected to the vacuum source. Similarly, unless a sheet passes over the cylinder 2, the next cylinder 3 will not be connected to the vacuum source, and so on. The regulator valve 9 is set so that when there is no sheet on the cylinder 1 there is only a low pressure in that cylinder, and the valve 12 will therefore close or remain closed, as the case may be. The trigger valves 12, 16, &c. can each be associated with cut-outs to stop the apparatus if a sheet fails to pass any of the transfer points: or a trigger valve can control the application of suction to a printing-cylinder which is rotated by suctionoperated means: or the first trigger valve can be operated by an electric solenoid which is energized by a detector switch responsive to a sheet entering the transfer apparatus, and so replace the regulator valve 9.
