Title: Improvements in or relating to the manufacture of sulphuric acid by the contact process
IPC: C01B17/76
Filed: 1933-06-26
Abstract: <PICT:0400143/III/1> In the contact process of sulphuric acid manufacture the removal of solid components from the burner gases and the absorption of the sulphur trioxide are both performed without any circulation of acid.  For example, the gases produced in the burner 1 are passed through a filter chamber 2 containing quartz fragments into the converter 3.  The reaction product after passing through a cooler 4 is absorbed in concentrated acid in a bell-seal apparatus 5. An insensitive contact mass preferably a vanadium catalyst is used.

Filed: 1936-07-02
Abstract: 462,709. Gear - cutting. SOC. INGRANAGGI MAMMANO, and MAMMANO, B. July 2, 1936, No. 18410. [Class 83 (iii)] Curved-tooth bevel or spur gears are generated by rolling the base circle C or base cone of the blank B, Fig. 17 relatively to a rotary tool F having cutting edges parallel to the tool axis, both blank and tool being rotated continuously in timed relation. Thus in Fig. 12 if the blank having a base circle C is rotated in the direction of arrow I while a tool U<2> has a corresponding tangential motion in the direction of arrow II the point V of the tool describes an involute curve VR on the tooth flank. Further movement of the blank relative to a tool U<1>, Fig. 13, similarly forms the involute ST of the opposite flank. The continuous rotation of the blank and tool produces a curved tooth form as shown in Fig. 9. Two finishing cutters F<1>, an external cutter for the convex flanks ED, Fig. 9, and F<2> an internal cutter for the concave flank AB are arranged on a common tool head, Fig. 15, the parallel edges being at the same distance r from the tool axis. In order to obtain the desired root space # of the teeth the cutters are arranged at an angle # Fig. 16. If N is the number of teeth to be cut #=#N. By modification of the angle # the cutters may be arranged at different radii. Other subsidiary roughing cutters R<1>, R<2> may be arranged on the cutter head within the angle # between the finishing cutters. In some cases the cutters may be extended beyond the tangent to the blank base circle so that clearance for the teeth is obtained.

Title: Reducing ferric oxide
IPC: C21B13/00
Filed: 1947-07-15
Abstract: <PICT:0634938/III/1> Ferric oxide is reduced to magnetic by maintaining, at, say, 500-1000 DEG  C., an enclosed bed of finely divided solid ore by feeding ore thereto and discharging treated solid therefrom, and fluidizing the bed by passing a gas upwardly therethrough which contains reducing constituents, e.g. hydrogen and/or carbon monoxide proportioned to reduce ferric oxide.  The ore 62 is conveyed from hopper 61 to fluidizing chamber 52 and transferred, fluidized by air entering at 66, through pipe 60 to the bottom of fluidized preheating bed 17 which is carried on apertured plate 18 in insulation-lined metal reactor 5.  The preheated solid travels, via dip-pipe 16 which keeps level of bed 17 constant, to combustion and oxidation bed 25 carried on apertured plate 26 and maintained at 750 DEG  C. by air supplied at 69.  The solid is again transferred by a level controlling dip pipe 24 to reduction bed 32 carried on apertured plate 33 and is discharged thence through level control pipe 72 and cooler 75 for separation of the magnetite.  The fluidizing and reducing gas entering at 36 is proportioned to reduce ferric oxide to magnetite with minimum formation of ferrous oxide and iron and is sufficient to fluidize all three beds with the assistance of air supplied at 69, 71. Cyclone 2 separates dust from waste gases from reactor 5 and fluidizing chamber 52, and returns it to reactor 5.  The reactor is heated to a sufficient temperature for starting up by burning fuel from pipe 73 in air from pipe 38.  A multiplicity of beds may be used in the reactor.

Title: Improvements in or relating to the separation of penicillins
IPC: F02M37/04
Filed: 1947-07-17
Abstract: Benzyl penicillins (e.g. G and X) are separated from aqueous solutions of crude penicillin by adding a water-soluble beryllium compound such as the acetate, bromide carbonate, chloride fluoride, hydroxide, oxalate or sulphate, preferably at a pH of 4.5-5.7, suitably 5.5, filtering off the precipitated beryllium salts of penicillin F and related aliphatic chain penicillins and recovering benzyl penicillins from the filtrate, e.g. by acidifying and extracting with isopropyl acetate.  The benzyl penicillins are isolated by extracting the isopropyl acetate solution with sodium bicarbonate, freeze-drying and recrystallizing from acetone: The precipitate of aliphatic chain penicillins may be acidified and dissolved in an organic solvent from which a partial separation of its constituents may be obtained by extraction with alkalis of increasing pH.  In examples: (1) an aqueous solution of penicillin is treated with beryllium chloride, the precipitate is filtered off and dissolved in isopropyl acetate, the filtrate is extracted with isopropyl acetate and both are converted to the sodium salts by treatment with aqueous sodium becarbonate and freeze-drying; and (2) a solution of sodium penicillin is treated with beryllium sulphate as in (1) and the final extraction of the precipitate fraction is made with sodium bicarbonate followed by sodium hydroxide giving, as well as the penicillin G fraction from the filtrate, two fractions from the precipitate consisting of penicillin F and what appears to be penicillin K.
