IPC: B01J8/44
Filed: 1957-01-16
Abstract: An apparatus for carrying out a fluidized bed process comprises a lower flared portion 3, Fig. 1, forming an intake for a part of the fluidizing medium, the upper part of the flared portion being spaced from the walls of the main part of the apparatus, the space being bridged <PICT:0834455/III/1> <PICT:0834455/III/2> by a grate 6 which slopes from the walls downwardly towards the flared portion.  The grate may be formed by radial or concentric members having overlapping portions, so that fine particles are prevented from passing into the chamber 7.  The fluidizing medium which enters through pipe 5 may have a different ratio of air to steam oxygen to steam or oxygen to carbon dioxide from that which is passed through line 2.  A Venturi 4 may be interposed between line 2 and flared portion 3.  Gas passing from the chamber 8 may be passed through pipe 21, Fig. 4, into a cyclone separator 50, the clean gas passing out through pipe 22 whilst the dust falls down tube 23.  An inert gas or gas manufactured in the apparatus and extracted by compressor 25 after cooling, is fed at 24 into tube 23 to maintain the dust in a slightly fluidized state.  After passing through valve 26 into chamber 27, the dust meets gasifying agents arriving through tube 28. These carry the dust through tube 29, 2a back into the chamber 8. The apparatus may be used for the production of hydrogen from producer gas containing steam by reduction with iron which may be produced by reducing iron oxide with producer gas.  Specification 723,332, Swiss Specifications 292,727, 292,859, and French Specification 1,050,572 are referred to.
Patent GB-412311-A (GB)
Title: Improvements in or relating to methods and apparatus for drying materials
IPC: F26B25/22
Filed: 1933-01-18
Abstract: 412,311. Drying systems. SOC. FRANCCOMTOISE DES BOIS SECS, 40, Rue GÚr¶me, Vesoul, Haute-Saone, France. Jan. 18, 1933, Nos. 1729, 1730, and 1731. Convention dates, Jan. 18, 1932, May 23, 1932, and July 23, 1932. [Class 34 (ii).] In the drying of wood or other material the charge is suspended in a weighing apparatus or balance, which is subjected to the action of means maintaining it in equilibrium if the drying proceeds in accordance with a predetermined law. If the drying proceeds too rapidly or too slowly, the apparatus is set in momentary disequilibrium, and operates, e.g., through suitable relays, elements adapted to vary the conditions of drying, e.g., the temperature or hygrometric state of the oven, or the velocity of the gas current, or the speed of the moving support if such be used. In one form, Fig. 23, the charge A in the dryer B is attached through levers to the graduated beam S of a Roman balance. Initial adjustment may be obtained by varying the weight of the counterpoise m, which is suspended from a runner r. This runner moves in accordance with the movements of a fingerpiece r' engaging in a groove formed in a continuously rotated cylinder r<5>, the groove corresponding in form to the predetermined law of desiccation. Movement of the beam from the position of equilibrium is transmitted through a rod u<1> to a pressure relay u which operates the air admission ports c of the dryer. It is preferred to operate the dryer at constant temperature. To prevent too rapid oscillation of the air admission ports, the pressure relay is also controlled by means acting in accordance with a predetermined law expressing the hygrometric state of the atmosphere in the kiln as a function of time. These means may comprise a gasfilled wet thermometer x<2> connected to a dynamometer x<3> acting on a lever x<1> to which a valve u<20> in the pressure relay is attached. The lever pivots on a member x<4> moved by a cam x<5> of profile determined by the hygrometric law. To give rapid restoration of the main balance beam s when it is excessively deflected, a lever attached thereto is caused to uncouple a clutch in the drive of the cylinder r<5>, the coupling being restored with the equilibrium of the beam. In another form, Fig. 1, the weight of the charge is applied to a lever l<1>, and the moving weight r is operated by a cam s<1>. Levers l<1>, s act through levers t<1>, t<2> on a single oscillating element t<3> controlling the pressure relay u. Dynamometers p<1>, p<2> are graduated to indicate theoretical and actual proportions of water in the charge.

Title: Apparatus for playing a race game
IPC: A63F9/14
Filed: 1932-01-20
Abstract: 397,165. Race games. BROOKER, H. T., 19, Branksome Road, Southendon-Sea, and WILLIAMS, L. E., 7, St. George's Road, Forty Hill, Enfield, Middlesex. Jan. 20, 1932, Nos. 1770 and 11499. [Class 132 (ii).] A race game apparatus comprises a number of travellers advanced along tracks towards a target or indicator by thrusts imparted directly thereto by propelling units, for example balls, receiving impulses from actuating devices manipulated by the respective competitors. A base 5, Figs. 1 and 2, has a plurality of sockets 4a, each of which may carry a pivotal member 3 to which is pivoted at 7, Fig. 5, the upper end of a channel-shaped track 2 fixed at its lower end to a base 8, Fig. 8. The latter carries a spring 9 which when depressed by means of a button 14 flicks a heavy ball 11 up the track to advance the traveller, for example, a model car 13 carried by a base 16 and guide strip 17, the end 12 of the spring 9 acting as a buffer to a descending ball. When the traveller reaches the top of the track 2, the forward end of the guide 17 abuts against the arm 19, Fig. 5, of an indicator 18 pivoted at 7, and rocks it into the vertical position where it is retained by a counterweight 21 which abuts against the traveller to prevent further forward movement thereof. In a competitive game the winner is he who first elevates his indicator 18. In another embodiment the base 5 carries a hand-spun flywheel 25, Fig. 3, which frictionally drives a bar 24 resting diametrically thereon. The bar carries a model hare 23 and a counterweight 31. In playing a game the competitors advance their travellers 16 as before to position them at the top of the respective tracks where the models lie in the path of and stop the hare 23, the bases 16 or the top ends 33 of the tracks engaged thereby being made resilient to render more difficult a winning location of a traveller. In a modification the springs 9 for propelling the balls may be flexed by a manually rotated cam. Alternatively the balls 11 may be propelled by a plunger and recoil spring.

Title: Process for the catalytic alkylation of isoparaffins
IPC: C07C2/62
Filed: 1944-02-03
Abstract: The alkylation of isoparaffins with olefins is effected in the presence of a catalyst phase comprising hydrogen fluoride as essential active ingredient, and which contains organic diluent of higher molecular weight than the alkylated isoparaffin, and less than 15 weight per cent of water, the water content of said catalyst phase being maintained at a lower weight per cent than the content of said organic diluent, and the accumulation of said diluent controlled so that the hydrogen fluoride concentration of the catalyst phase is kept within the range of 65-95 weight per cent.  The accumulation of organic diluent may be controlled by withdrawing part of the used catalyst and replacing it with fresh hydrogen fluoride or regenerated catalyst having a higher concentration thereof.  The methods described in Specification 565,467 may be used to control the composition and concentration of the catalyst phase.  The process is applicable, for example, to the alkylation of isobutane with propylene, butylenes or amylenes.  With isobutane and gaseous olefins under substantially liquid phase conditions and about 10-65 DEG  C., the optimum concentration of hydrogen fluoride is about 70-85 per cent.  A paraffin-olefin mixture with isoparaffin preferably in a molar excess of 4-10 : 1 or more over olefins is fed with fresh hydrogen fluoride catalyst, which may contain minor amounts of other materials such as water or boron fluoride, to an agitated reaction zone such as a turbo-mixer at about - 18 to 95, preferably 10 to 65 DEG  C., and sufficient pressure to liquefy.  The space time, i.e. volume of catalyst over volume rate per minute of hydrocarbons charged, is usually about 5-80.  Catalyst is separated from hydrocarbon phase in a settler, part being recycled, and part regenerated as by distillation to separate purified hydrogen fluoride which may be stored or re-cycled.  The hydrocarbon phase is fractionated into gasoline range products and higher, light gases, and unconverted isoparaffin which is recycled.  Results are given of the alkylation of a hydrocarbon charge containing 70 per cent isobutane, 16 per cent n-butane, 9 n-butanes, 4 isobutene, and 1 C5 and above, with anhydrous HF at various temperatures, space times, and speeds of revolution of the agitator, with different values of total acidity in the catalyst phase.
