摘要： 742,367. Hot-water boilers. STILL & SONS, Ltd., W. M. March 4, 1954 [March 12, 1953], No. 6830/53. Class 64(1). In a hot-water boiler comprising a water drum 10 in which the water level is maintained within predetermined limits A and B, e.g. by a ball valve 18 and discharge pipe 26, a pipe 30 extends down from an opening 28 in the lower part of the drum, then upwards to a height above the highest water level A, and then downwards to a discharge point 36 below the lowest water level B. A burner 42 heats the pipe 30 most intensely at a part so spaced from the opening 28 and discharge point 36 that the resistance to flow is greater towards the former than the latter. As a result, the heated water flows through the pipe 30 from the opening 28 to the discharge point 36. The pipe 30 is a helical coil connected at the top to the opening 28 and at the bottom to a pipe 32 which rises in the tank above the level A and is surrounded by a pipe 34 open at the bottom and closed at the top except for a small hole 40 for the escape of steam. A perforated hood 50 is provided over the opening 28. The drum 10 has a flue 14 and an associated baffle 54. Steam pressure in the boiler controls valves 20, 44 respectively regulating the rate of water supply to the drum 10 and the gas supply to the burner 42. Two or more pipe coils 30 may be provided, arranged if desired concentrically. Dimensions are given.

摘要： 501,781. Separating gases by adsorption. STILL & SONS, Ltd., W. M., and STILL, E. H. Dec. 3, 1937, No. 33490. [Class 1 (i)] Apparatus for the recovery of solvents from air by passing the air through adsorbent carbon or other adsorbent material, and thereafter recovering the solvent by passage of steam through the adsorbent, comprises a chamber a with a perforated false bottom a supporting the adsorbent, a perforated false top a , a roof separating chamber a from a second chamber b provided with dirt extracting filters b through which the air is driven by a fan c, the roof and the floor being provided with valves d, e respectively for 'the entry and discharge of the air, and with an outlet l and inlet k for the steam. The valves, which tend to be kept open by springs d , e , are adapted to be closed by a pivoted lever i acting through cables g having tension springs g incorporated in them. The steam outlet pipe l leads to a water-cooled condenser m, the condensate passing to a tank o provided with a float and indicating rod p . A valve l on pipe l is adapted to open if the pressure falls below atmospheric. Each dirt filter bl consists a felt or textile sleeve enclosed between two concentric perforated pipes secured to the walls of chamber b and communicating at one end with the delivery pipe of the fan c an at the other end with an opening closed by a door q which is removed for purposes of cleaning the filter. The flue pipe f which is formed with a stoppered vent pipe r for enabling the discharged air to be tested by smell to ascertain if the adsorbent is saturated. Reference is made to the recovery of solvents used in dry-cleaning process.

摘要： In a dry-cleaning apparatus consisting of a drum 4 having perforated areas a rotating or oscillating in a closed container 2 containing solvent, the interior of the drum is provided with a number of shelves 8 extending towards the axis and mounted on unperforated areas of the drum. The shelves may be flat or curved in cross section. The drum may be oscillated by a pinion and rack bar gearing. In operation, the clothes are carried upwards by the shelves together with benzine or other dry cleaning liquid which is contained in the unperforated pocket. At a higher position the clothes fall off the shelf and the trapped benzine pours over them. The drum may be rotated continuously, when the shelves are mounted at the lower edge of the unperforated area.
