Abstract: A fluidized bed apparatus suitable for the combustion of fuel has a baffle assembly arranged in the freeboard above the fluidized bed level. The assembly is in the form of a perforate duct which defines within it a passage connecting with the gas exit of the apparatus. Gases issuing from the bed, in use, and carrying bed material impinge upon the duct and are arranged to follow a vortical path around the duct, resulting in a deceleration of the particles which fall back into the bed. The gases pass into the duct for exhaust substantially free from contamination by bed material. The baffle assembly is of particular value where a gas flows horizontally to a gas exit and prevents or substantially reduces elutriation.

Abstract: The quantity of a substance in a specimen is determined in the presence of a contaminant by using a first beam of radiation within an absorption band of the contaminant and a second beam of radiation within both an absorption band of the contaminant and an absorption band of the substance, the respective intensifies of the beams after incidence upon the specimen being detected and converted into electrical signals, functions of which are subtracted to indicate directly the quantity of the substance in the specimen. The beams may be transmitted through a paper sheet 40 with the aid of diffuse reflectors 41, 43, to determine the water content despite carbon contaminant particles 46 (e.g. from recycled pulp), suitable wavelengths being 1.8  mu  and 1.94 mu .

Abstract: A fluid suspension unit, particularly for heavy motor vehicles, comprising an outer cylinder and an inner cylinder slidably mounted within the outer cylinder, the outer and inner cylinders defining therein a chamber of variable volume containing hydraulic fluid and compressed gas. A diaphragm divides the chamber into two portions and has an opening therein which is normally closed by a mushroom valve. The upper portion of the chamber has a constant volume and a prefixed pressure and the lower portion has a variable volume and a variable pressure, lower or at most equal to that of the upper portion. The mushroom valve, normally closed, opens mechanically only when the suspension reaches a predetermined degree of compression that is when the pressure in the two portions of the chamber are the same. The valve is closed by gravity when the suspension returns to the same predetermined degree of compression.

Abstract: A device that regulates an outlet valve on a self-discharging centrifugal drum which diverts the closure fluid from a closure compartment that moves the piston valve from a closure position while the solids space is being partly or completely emptied, has, in addition to a supply line that supplies closure fluid to the closure compartment, an operating-fluid line in which a compressed air-controlled operating-fluid meter is positioned downstream of one shut-off and upstream of another shut-off. The meter consists of a housing divided by a tightly stretched and flexible diaphragm into two compartments, one that can be altered in capacity and that accepts operating fluid and a second that can be pressurized. This system ensures that a precise volume of operating fluid will be supplied to the outlet valve and determines the amount of solids to be removed.
