Filed: 1929-12-30
Abstract: 332,178. Electrolux, Ltd., (Assignees of Inventia Patent-Verwertungs-Ges.). Jan. 4, 1929, [Convention date]. Washing-machines with means for circulating liquids.-A washing-machine comprises two containers A, B, of which the liquid spaces communicate with one another, for example, through a gap between the bottom of the casing 10 and an imperforate hollow partition 16 and the machine is provided with means for periodically varying the relative pressures above the liquid in each container, as by introducing compressed air alternately into the air space of each container, whereby an oscillating movement of the liquid is produced. The source of the compressed air may be the pressure side of a vacuum cleaner. Alternatively the air spaces may alternately be subjected to suction. Flap or other valves 25, 26 in the chamber 19 communicating with the supply pipe 20 from the cleaner 21 are operated by floats 34, 35 and a detent mechanism 39, 41 is provided to render the floats inoperative until a predetermined pressure is exerted. Operation of the valves admits the compressed air in the containers A, B alternately through apertures 23, 24 respectively. 'The gap beneath the partition 16 may be partially closed by a perforated extension of the partition to prevent movement of the clothes from one container to the other. Each float mechanism may be housed in a separate chamber formed within the hollow partition, each chamber communicating with one of the containers A, B. Additional liquid circulating devices may be provided.

Abstract: 818,320. Rotary furnaces. SMIDTH & CO. A.S., F. L. Dec. 23, 1957, No. 39914/57. Class 51 (2). In a rotary furnace for the burning of cement raw materials, lime or ores in which part of the interior is divided into compartments 4 by four longitudinal partitions 3 formed with sector-shaped end flanges 11, at each end, each partition is truncated towards the kiln shell 1 so that it presents an edge 8, Fig. 6, perpendicular to the furnace axis and another edge 9 inclined towards the axis at an acute angle, each flange being bent at 14 to mate with the partition edges so formed. The flanges are associated with a central hexagonal plate 19, and the line 14 slopes, being related to the direction of rotation of the furnace so that at the inlet end of the compartments the trailing end of the line is nearer to the axis than the leading end. The partitions have inclined conveying ribs 18 sloping in opposite directions on both faces, the end ribs 17 being somewhat shorter than the others. During operation, material reaching the inlet end of the compartments is cut through by the outer parts 13 of the flanges and lifted into the compartments 4 by the partitions adjoining the flanges. On further rotation, the leading corner 16 of the oblique end 13 of the flange 11, imparts a forward movement to material filling towards the centre of the furnace, preventing spillage backwards. At the outlet end of the compartments the shape of the flanges assists discharge of the material by depositing it on the kiln shell in advance of the plane of rotation of the leading corners of the outlet flanges.

Abstract: H2S is removed from fuel gases by washing them with ethylene sulphite or a homologue thereof containing SO2 in an amount greater than that necessary stoichiometrically to react with the H2S or alternatively SO2 may be added to the gases to be washed.  The sulphur produced may separate in the washing vessel and be removed therefrom or by raising the temperature of the washing liquid the sulphur may be kept in solution in the ethylene sulphite and recovered after the solution has been withdrawn from the washing vessel.  Gases containing SO2 may be washed with ethylene sulphite and the resulting solution brought into contact with H2S to produce sulphur.

A flexible tube 2, with an internal diameter 4 smaller than the external diameter 3 of a pipe 1, is fitted on the end of the latter by first inserting in the tube 2 rigid rings 5, 6 of internal diameter greater than the diameter 3, spaced apart so that the tube 2 contracts on to the outside of the pipe 1 in the interval between the rings and thus forms a seal. As the pipe 1 is pushed into the expanded tube 2 its end enlarges the tube 2 and forms another seal at 10. The rings 5, 6 are shaped to facilitate their insertion in the tube 2 and the inside of the ring 6 is flared to facilitate the entrance of the pipe 1.
