Title: Improvements in or relating to processes for carrying out exothermic chemical reactions
IPC: C01C1/04
Filed: 1926-10-26
Abstract: 268,722. Soc. l'Air Liquide, Soc. Anon. pour l'Etude et l'Exploitation des ProcÚdÚs G. Claude, (Assignees of Soc. Chimique de la Grande Paroisse Azote et Produits Chimiques). April 1, 1926, [Convention date]. Catalytic processes and apparatus.-In exothermic reactions such as the synthesis of ammonia, heat is conveyed from hotter to cooler parts of the catalytic mass by means of the reaction gases before they come into direct contact with the catalyst. In one arrangement, the reaction gases entering a pressure vessel are led through a central tube B to the hotter end of the catalytic mass, then by tubes C to the cooler end again, and finally by tubes C<1> back to the hotter end, where they pass into the surrounding catalyst. The tubes C may be partly heat-insulated, and may be arranged coaxially inside the tubes C<1>, so as to minimize loss of heat in transit from the hotter to the cooler regions. A number of separated parallel tubes may replace the central tube B. The tubes C, C<1> may be coiled, and may be pointed at their ends, to facilitate their expansion within the catalytic mass. A part of the fresh gases may be led between the heat-insulated catalyst container J and the pressure tube H, in order to cool the latter, before entering the upper end of the catalyst container J. In another arrangement, the reaction gas entering the pressure vessel is distributed to an outer series of tubes embedded in the catalyst, and after passing up through these tubes is conveyed downwards through an inner series and finally up through a central tube and into contact with the catalyst. An independent current of gas is conveyed between the catalyst container and pressure tube and is discharged to the outside of the pressure vessel, as described in Specification 268,721. Specification 150,744 also is referred to.

Abstract: 913,384. Cup dispensers. AUTOMATIC CANTEEN CO. OF AMERICA. Aug. 4, 1960, No. 27107/60. Class 78 (1). A paper cup dispenser (Figs. 1, 8) is formed as a ring 12 furnished with cams 17. Each cam 17 is furnished with a portion 18 and a portion 42 so that, as the cams are simultaneously rotated, the lip 19 of lowermost cup 20 passes between the two portions of each cam and permits the said cup to drop. Cam portion 42 is cut in such a way that the lip makes line engagement with each cam so as to avoid stoppages. Each cam is made of nylon. Adjustment for differing sizes of cup (Figs. 1 and 4).-The ring 12 has a fixed framework 27 secured at 28 to fixed supports 13 and carries the six cams 17 pivotally as shown. The adjustment is made by outer ring 26 which has top and bottom portions each furnished with curved slots 31, there being corresponding radial slots 30 formed in framework 27 so that when outer ring 26 is rotated the curved slots 31 cause pin 23 of each cam 17 to move inwardly or outwardly along radial slots 30, thus displacing the cams to allow for cups of differing diameters. Dispensing operation of cam (Figs. 4 and 5).- This is effected by actuator ring 38 which is contained within the framework 27 and carries for each cam a link 48 pivoted at 49 to said actuator ring and linked at 52 to crank 56 secured to the cam. The operator grips arm 39 and thereby oscillates ring 38 to cause each cam to move in and out so as to release each time a cup 20.
