Title: Improvements relating to the treatment of molten pig iron or similar iron alloys rich in carbon
IPC: C21C5/32
Filed: 1949-10-25
Abstract: In the refining of pig-iron or other high carbon iron alloy with an oxygen-containing gas the molten metal is treated with the oxygen-containing gas in a cylindrical furnace rotating about a horizontal axis at a peripheral speed, during at least a part of the time, of one metre per second, the oxygen-containing gas being introduced above the level of the molten metal.  The oxygen, which may be pure or commercial oxygen or oxygen-enriched air, may be supplied centrally of one end of the furnace, alone, or in admixture with other gases, e.g. an ejector nozzle may be used to mix the oxygen with the furnace gases, and may or may not be directed against the bath.  The speed of rotation of the furnace may be varied during the process.  The oxidizing gas may be shut off, if desired to allow some reaction, e.g. desulphurizing, to take place in a reducing atmosphere.  The slag may be removed continuously or intermittently. The Specification as open to inspection under Sect. 91, includes also the use of a much slower rotational speed.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the manufacture of capsules made of cellulose esters which are capable of shrinking and are stored in the air
IPC: B29D99/00
Filed: 1929-09-12
Abstract: 319,736. Kalle & Co., Akt.-Ges. Sept. 27, 1928, [Convention date]. Capsules, non-metallic, compound and adhesive. -Shrinkage of water-swollen capsules made of cellulose esters, for example cellulose acetate, is prevented by treating them in a water miscible, non-volatile liquid which does not possess a greater swelling action upon the cellulose ester than water, for example glycerine of 28‹ Be., polyglycol, sorbite, glycerine mono-lactate, or mixtures thereof. Alternatively, the capsules and the like may be immersed in a dilute aqueous solution of the impregnating agent or in an aqueous salt solution, for example 30 per cent sodium chloride, and then in the impregnating bath proper. After impregnation the adhering liquid is eliminated, for example by centrifuging. Capsules and the like impregnated in this manner can be stored without shrinkage or deterioration. Before use, they are immersed in water for a short time to replace the impregnating liquid by water. In examples, water moist bottle capsules made of cellulose acetate are immersed in glycerine of 28‹ Be., or firstly in aqueous glycerine monlactate or firstly in a. 30 per cent sodium chloride solution and then in a mixture of polyglycol and glycerine.

Filed: 1934-09-29
Abstract: 434,759. Valves. SIMS, A. V., 2, Rector Street, New York, U.S.A. Sept. 29, 1934, No. 27929. [Class 135] A valve, more particularly for use in reciprocating pumps but applicable to other purposes comprises a valve seat 7 with a central post 2 extending therefrom, a valve disc 8 surrounding the post and adapted under the action of fluid pressure to move towards and away from the seat 7 and to rotate about the post 2, and a guard-plate 1 pressed by a spring 9 towards the disc 8, the movement of the disc 8 and guard-plate 1 being cushioned by a number of concentric liquid-dashpots associated with the plate 1 and coming into operation successively during the movement of the plate 1. The rotation of the disc is caused as the fluid flows through the ports 5 and between the disc 8 and plate 1 by means of suitably-shaped deflectors 4 or grooves either on the upper surface of the disc or on the lower annular surface 3 of the plate 1 which is spaced from the disc or on both. In the latter case, the deflectors on one of the members may oppose those on the other so as to check excessive rotation of the disc. As shown, the inner dashpot 15 and outer dash 23 are formed on the stem head 16 and the coacting inner dash 17 and outer dashpot 22 are formed on the plate 1, but this arrangement may be reversed. Also, three or more concentric dashpots may be provided. During the upward movement of the plate 1 the outer dash 22 comes into operation after the inner dash 17, and during the reverse movement, the dash 22 becomes inoperative before the dash 17. As the plate 1 falls, a partial vacuum is formed in each dashpot and so lessens the impact of the plate 1 on the disc 8. Specification 5856 /07, [Class 135], is referred to.
