Patent FI-964913-A (FI)
Inventor: MAEKIPIRTTI SIMO
IPC: C22B/
Filed: 1996-12-09
Abstract: The process according to the invention controls the performance of a vertical suspension smelting process or a so-called flame smelting process. The control of the performance is based on controlling the reactions of the semi-rigid conversion layer of the suspension oxidation, which conversion layer is formed from the oxidation product when the suspension is tapped out, and controlling the quantity ratios for the iron sulphide oxidation between the suspension oxidation and the conversion oxidation. Both the customary process and the process according to the invention make use, in the selective oxidation of the still-remaining iron sulphide of the suspension oxidation product, of ferric-ferro-iron conversion in both the solid and molten states. In the process according to the invention, it is possible, inter alia when producing valuable metal-rich sulphide stone, to leave, when oxidizing the suspension, a part of the iron sulphide unoxidized when the selectivity of the oxidation process begins to decrease, when the activities of the valuable metals and iron in the sulphide smelt are altered. In this connection, more ferric iron, in the molten state, is used, in addition to the ferric iron content in the solid magnetite of the oxidation product, for selectively oxidizing the sulphidic residual iron in the suspension oxidation product. In this connection, the ferric iron content of the oxidation product is supplemented with the ferric iron content in the preoxidized slag phase which is used for the additional oxidation. When the suspension is tapped out, the progress of the reaction, the reaction delay time, the contact surface between the reaction components, and the heat transfer which is required for the conversion reactions, are improved substantially for the semi-rigid conversion layer, which is formed from the oxidation product of the enrichment and which is laminar in nature, by mixing the conversion layer with the upper layer of the slag smelt, which smelt lies beneath it and is preoxidized if required. The mixing is performed using the high-speed product gas streams of the preoxidation and the additional fuel, the quantity of which streams can be regulated. The novel process offers versatile and extensive selection and control possibilities for improving the performance of the vertical suspension smelting process.

Title: Improvements in and relating to aerial bombs, self-propulsive in or on water
IPC: F42B17/00
Filed: 1942-01-27
Abstract: 554,733. Aerial bombs. KEMP, L. C. Jan. 27 1942, No. 1107. [Classes 9 (i) and 9 (ii)] A bomb contains a rocket propellant adapted to be fired by a time or impact fuze so that the bomb may be forced backwardly to take an indefinite path in or on water or in the air near the water until it strikes an objective when it is exploded. The bomb comprises a casing 1 with end air-chambers 4, 5 and a central explosive chamber 3 surrounding an inner tube 6 which contains propellant burning material 7 and a gaine 12 or pressure fluid. The tube opens into a flared portion 6a containing an impact or time fuze 9, 9a, so that on impact with the water, the propellant material is fired and the gases issuing from the aperture 6a causes the bomb to move backwardly either in or on the water, or in the air near the water amongst shipping. If solid impact occurs during backward movement, an impact fuze 16 is fired, but if solid impact does not take place, then the explosive is ultimately fired through the propellant material and the gasine. A fuze 17 with a harder setting like the propellant fuze 9, 9a may be provided, so that should the bomb make impact with a body on its descent from the crraying plane, it will explode. The fuze 9, 9a may comprise a striker mounted on a transverse wire and a percussion cap. In a modification, the propellant tube may be situated in the front air chamber and not pass through the explosion chamber as previously described. Stabilizing pins 2 are fixed to the rear of the bomb.

Title: Improvements in the production of yeast
IPC: C12N1/18
Filed: 1927-01-14
Abstract: 294,123. Sak, S. Jan. 14, 1927. Yeast.-Relates to the manufacture of yeast by processes in which, during fermentation, yeast containing wort is withdrawn and centrifuged, fresh wort or solutions of nutrients or chemicals or centrifuged wort or water being usually simultaneously added. According to the invention, a large or a small part of the centrifuged yeast is returned to the fermentation vat after a short or long period in a controlled manner for a short or a long time with the object of maintaining during that time a certain weight of yeast per unit volume of wort in the fermenting vat. This density of yeast may be maintained at such a value that the withdrawn wort is incompletely fermented and contains alcohol; or at a higher value so that the withdrawn wort is completely fermented but still contains alcohol; or at a still higher value so that alcohol is either not formed or disappears during the fermentation. The returned yeast has also the effect of reducing the grade of generation of the yeast. This rejuvenation may be increased bv the further addition of fresh yeast prepared outside the system to the fermenting wort or to the storage vat for the centrifuged yeast. The centrifuged yeast may, before its return, be passed through fermentation vats with wort of the same mutual concentration in respect of a nutrient such as sugar, the yeast being added in such quantity that a smaller yeast density is established, thereby increasing the formation of alcohol and the activity of the zymatic enzymes, which is conductive to regeneration. The centrifuged yeast can be separated from the wort by pressing. The returned yeast and the fresh yeast may be in the form of compressed yeast or otherwise. At certain periods, especially when centrifuged wort is added to the fermentation vat, the withdrawn wort may be returned to the vat instead of yeast centrifuged therefrom.. The fermenting wort is aerated and kept at a temperature of about 30‹ C.

Abstract: 557,444. Shock-absorbers. PHILLIPS & POWIS AIRCRAFT, Ltd., and MILES, F. G. Feb. 10, 1942, No. 1764. [Class 108 (iii)] [Also in Group XXXIII] In an aircraft landing element mounting of the kind comprising a lever pivoted on a leg and carrying the landing element such as a wheel, and a shockabsorber connected between the lever and an anchorage to oppose swinging of the lever under landing and taxiing loads, partial retraction or shortening of the overall length of the mounting is obtained by adjustment of the anchorage of the shock-absorber by a screw-jack. As shown, the lever 6 carrying the wheel 7 is pivoted at 5 to the leg 3 of and an extension 10 of the shock-absorber 9 is connected to the plunger 12 of a screw-jack arranged in the housing 13 and operated by a sprocket 14. A leg and a wheel fairing 15, 16 are provided, including a flap 17 connected to move with the lever to close the gap between the wheel and the fairing 16 when the wheel is in the retracted position shown. A shock-absorber acting in compression may instead be connected to the lever between the pivot 5 and the wheel axle. According to the Provisional Specification in an undercarriage having a leg involving telescopic movement against hydraulic resistance, pipes may be connected to the spaces above and below the hydraulic piston and to a pump so that the telescopic parts may act as a hydraulic jack for shortening the overall length of the leg. A similar device may be used in the case of a pneumatic leg. When the leg includes a helical spring the upper abutment of the spring may be in the form of anut through which the upper turns of the spring pass so as to serve as a screw-thread, so that by turning the nut member the spring with the wheel may be moved upwardly to effect the shortening of the leg. The nut may be an internally-hollowed annulus crammed with steel balls or may have a helical track or groove corresponding to the pitch of the spring. In the case of landing element mountings of the kind in which the landing element is carried by a lever pivoted to a leg the partial retraction may be effected by varying the effective length of the shock-absorber or by axial displacement of or by treating the alignment of two shock-absorbers that are at least normally in axial alignment.
