The N-alkyl products may be prepared by direct alkylation of the N-unsubstituted compounds.  The N-acyl-21-acylates are prepared from the N-unsubstituted 21-ols by acylation, and on heating with aqueous acetic acid the N-acyl group is selectively removed; both acyl groups are removed with sodium methoxide in methanol. The 9a -halo-11b -ols of the invention may also be prepared by oxidation to the 11-ones before pyrazole ring formation with subsequent reduction after the pyrazole ring is formed.  11b ,17a ,21 - Trihydroxy - 21 - methyl - 5a -pregnane-3,20-dione is prepared by hydrogenation of the D 4-pregnene.

Abstract: 575,564. Transformer cores. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. March 27, 1944, No. 5624. Convention date, March 27, 1943. [Class 38 (ii)] A three-phase magnetic core comprises three V-shaped members formed of layers of magnetic material bonded together by insulating material and bent across the width of the strips, the two ends of each member being so shaped that they form butt joints with the ends of the other members at the axis of the core from which the three members radiate in directions mutually displaced by 120 degrees. A strip of magnetic material may be continuously wound to form the rectangular loop shown in Fig. 3, the laminations being separated and bonded by a plastic insulating material. Cuts 24, 25 inclined at an angle of 120 degrees at the top and bottom of the coil make two V-shaped cores with surfaces at the ends so shaped that three cores 4, 5, 6 may be placed together as shown in Fig. 1 to form a three-phase structure, round the three legs 7 of which windings 1,'2 and 3 may be placed. The surfaces forming the butt joints between core members extending between the axis 12 and outer edges 10, 13, 14 may be machined and then etched to remove burrs as described in Specification 540,662. The core members 4, 5, 6 are held together by straps 16, 17, 18 which hook into a triangular member at the bottom and are held by adjustable screw connections 19, 21 in a triangular member 15 at the upper end. Also described is a construction in which each core member is divided centrally by a conducting strip to prevent cross flux, insulated from the laminations and lying in a plane containing axis 12, Figs. 5, 6 (not shown). As a further modification, core members of cruciform section are described which are made similarly to those previously described but from a strip which is wider at its middle portion, Figs. 7-10 (not shown). Preformed coils may be placed on the cores which are first cut across the legs 7 and then joined by a butt joint, or the low voltage winding may be wound on the core and the high voltage winding slipped over it.

Title: Process and plant for making steel
IPC: C21C5/28
Filed: 1949-03-03
Abstract: In a process for the manufacture of steel by conversion of molten pig iron, the physical and chemical characteristics of the charge and the oxygen content of the blast used in the first phase of blowing are chosen so that an excess of heat is obtained to compensate for the loss in heat during the second phase of blowing with an oxycarbonic mixture in which the ratio m, of the number of moles of endothermically dissociating gas to the number of moles of oxygen before dissociation, is at least equal to 1, and the change-over is made when the number of moles of oxygen to be incorporated per metric ton of pig iron is at least one-third, in an acid Bessemer, and at least three-sevenths, in a basic Bessemer conversion, of the moles of oxygen per metric ton already incorporated in the charge during the first phase.  The first phase may be carried out with oxygen-enriched air-25-35 per cent of oxygen, and the ratio m in the second phase may be between 1 and 2.  The nitrogen content of the oxycarbonic mixture should not exceed 3 per cent.  The area of the tuyeres and the blast pressure may be such that the addition of oxygen during the second phase does not exceed 500 moles per metric ton of metal.  In a basic Bessemer converter the area of the tuyeres may be 10-20 sq. cms. and in the acid Bessemer 6-10 sq. cms. per metric ton of pig iron and the diameter of the tuyeres may be 8-13 m.ms.

Abstract: 996,213. Valves. P. G. TACCHI. May 8, 1962 [May 8, 1962], No. 6066/61. Heading F2V. Means for testing a hot and cold water mixing valve consists of two jigs 18 between which the valve 10 is spring held, each jig is connected to a cold water supply via a line 23, a flow gauge 19 and a reducing valve 20, a thermometer 21 and a pressure gauge 22 being associated with each line 23. Before the valve 10 is placed in position the flow through each line 23 is equalized. The method of testing entails inserting the valve between the jigs 18 and manually adjusting the valve until the flow of cold water through both inlets is the same as would obtain if hot and cold water supplies were connected thereto, and the mixture at the outlet was at the desired temperature. Since the valve is also controlled by a thermally responsive element and both inlets are supplied with cold water a further adjustment of the manual control is necessary to compensate for the action of the thermal element, which further adjustment can be checked against previous experimental results or a formula. By employing cold water only, the performance of the valve in normal use to provide a given outlet temperature, by mixing hot and cold water, can be ascertained.
