Abstract: 1,231,858. Dry-cleaning apparatus. A. L. M. BRILLET. 25 April, 1968 [3 May, 1967; 23 Nov., 1967], No. 19703/68. Heading D1A. Textile articles are cleaned by first agitating them in a solvent and then subjecting them to a pre-prepared aqueous solution supplied at a predetermined temperature and water content. As shown, cleaning takes place in a horizontal perforated drum 1 to which solvent is supplied from tank 8 through valve 25 and from which it is drained through valve 32 to working solvent tank 6. Pump 15 draws solvent from tank 6 and white solvent tank 5 and feeds it through filter 9 to tank 8. Surplus solvent returns to tank 5 via overflow 23. Solvent may be pumped from tank 6 by. pump 15 to distiller 20 and returned through cooler 27 and separator 28 to tank 5. The acqueous solution is prepared in tank 7 from solvent fed from tank 8 and solvents, soaps and water from containers 33. In operation after the solvent has been drained from drum 1 the solution is drawn from tank 7 by pump 36 and delivered through spray 39 to drum 1 and the solution may be circulated by opening valve 43 to connect drum 1 with tank 7. Tank 7 includes a heater 46, a thermometer 47, a thermostat 48 and an agitator. Finally cleaning is completed by circulating white solvent through drum 1 and then the articles are rinsed. The articles may be dried by means of a fan 50 which removes the vapour laden air from the drum 1 and passes it through a condenser 51 and heater 52 before returning it to the drum 1. A re-cycling arrangement e.g. for applying a finishing composition is provided comprising a blower 54, heater 55 and solution sprayer 56. Alternatively, Fig. 3 (not shown), one outlet may lead to two fans and respective drying and recycling circuits. In a modification, Fig. 4 (not shown) two tanks (6a), (6b) for working solvent and dirty rinsing solvent are provided. In the modification illustrated in Fig. 6, (not shown) the drum can be rotated continuously or alternately in opposite directions at various speeds. Steam may be fed to the drum.

Abstract: 404,623. Control of D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Whiting, M. A. ; 1698, Rugby Road, Schenectady, New York, U.S.A.) July 13, 1932, No. 19834. Convention date, July 13,1931. [Class 38 (iii).] Varying E.M.F.; regenerative and non- regenerative braking.-When a motor 13 is overhauled by its load to such an extent that the regenerated power would be harmful to the prime-mover driving the supply Ward- Leonard generator 19, a relay 42, responsive to the rate of change of the regenerated power, energizes a contactor 21 which releases the electromagnetically controlled mechanical brake 28. A heavy overhauling load is thus anticipated and damage prevented. The relay 42 comprises an armature 40 energized across a reactor coil 48 connected across the generator 19, and a field coil 41 energized across a reactor coil 45 in the motor armature circuit. The relay overcomes its spring bias to close its contacts when the magnitude and rate of change of the motor power, exceeds a certain value in a regenerative direction. The separately excited field 26 of the generator 19 is regulated by resistances 59, under control of a controller 27. The contactor 21 has a holding coil 35 connected across the main motor armature. The brake is applied when the controller is in its neutral position. The brake controlled by the relay 42 may be an auxiliary brake, and may take the form of a rheostatic brake, Fig. 2 (not shown).

Abstract: 147,830. Ray, W. R. Jan. 15, 1919, [Convention date]. Air and steam pressure sprayers; rotary apparatus.-An oil burner of the rotary type comprises a centrifugal atomizer caused to rotate by a steam turbine, air being driven in an annular stream past the periphery of the atomizer and carrying the atomized oil into the furnace. Steam is supplied under pressure to a pipe 13 and passing through nozzles 10 impinges on the blades 9 of a rotor 5 secured to a hollow shaft 3 which is caused to rotate, the steam escaping by an outlet 12. The rotating shaft 3 is mounted in ball bearings 18 cooled by an air current deflected from a baffle-plate 23 and passing through a chamber 26 and tubes 27 to a chamber 28. The bearings may in a modification be water-cooled. Secured to the shaft 3 are two tapering cups 30, 31 spaced apart to form an annular chamber 33, the inner cup having a flange 38 and perforations 39 leading to the chamber 33. Oil is supplied through a stationary pipe 35 secured in the turbine housing 5a and having a flanged cap 37 and opening 36 through which the oil reaches the cups 30, 31. The oil on reaching the cups passes partly through the perforations 39 and is centrifugally projected in an atomized state partly by the inner and partly by the outer cup into an annular air current, which is induced by steam nozzles 54 through induction nozzles 50 and which leaves a nozzle 2 at high velocity, past guide vanes 40 and 41. This air current serves to project the atomized oil into the furnace. In case the turbine becomes inoperative and the oil is not centrifugally atomized, but flows out of the cup 30, steam is supplied to a pipe 63 and discharged through a nozzle 60 to spray the oil into the furnace.

Title: Improvements in or relating to causticizing units or apparatus
IPC: C01D1/22
Filed: 1925-08-12
Abstract: 265,669. Mount, W. D. Aug. 12, 1925. Alkali hydrates.-A eausticizing unit comprises a casing through which one of the chemicals is passed. means for admitting the second chemical to the moving body of the first chemical, means for bubbling a hot gas through the moving mixture of chemicals to heat and agitate the mixture, and means for effecting an indirect heat interchange between the exhaust gas and one of the ingoing chemicals preliminarily to heat such chemical by the otherwise wasted heat of the exhaust gas. As shown in Fig. 1, the casing A consists of superimposed sections 1 mounted on a pan 2, and is closed at the top by a heat-interchange device 3. Between adjoining lower section 1, plates or pans 8 are clamped, each plate being flanged upwardly as at 9 to form an annular reaction pan. A dome 10 is mounted over each flange 9, e.g. by brackets 11, the lower edge extending beneath the liquid level. An upper annular pan 21 having a conical depending outlet 23 is positioned beneath a pan 25 which receives the condensed liquid from the heat-interchange 3. a pipe 26 carrying the condensate outside the casing A. In operation, sodium carbonate which may be a solution of soda-ash, is introduced through a pipe 18 into the casing 3 and surrounds vertical pipes 5 through which the exhaust gases pass to an outlet 4, the sodium carbonate leaves through an inverted U-pipe 19. which ensures that the casing 3 is maintained substantially full. The pipe 19 feeds the pan 21 and the overflowing liquid is, in virtue of the conical outlet 23, poured over the upper dome 10 in an inverted conical stream. The second chemical, i.e. milk of lime, is admitted to the upper pan 8 by a pipe 15 and the mixture overflows through an external pipe 16 to the next lower pan and from thence through a similar pipe to the bottom pan 2 from which it is drawn through a pipe 24 and reduced to a marketable condition in the usual manner. Steam or air, or a mixture of both, is forced through a pipe 12 into an inverted bell 14 from whence it bubbles upwards through the liquid in the pan 2. The steam or air then passes into the lower dome 10 and bubbles through the liquid in the lower pan 8. This is repeated in the next pan 8 after which the steam or air passes through the liquid descending through the opening 23 and passes around the edge of the drip-pan 25 to the pipes 5 of the heat-interchanger 3. If desired, the lime could be introduced through the pipe 18 and the sodium carbonate through the pipe 15. If the soda-ash contains sodium sulphide, this is converted into sodium thiosulphate which is then destroyed by oxidizing it to the sulphate.
