Abstract: Possibilities are to be provided to clean, by physical methods, contaminated finely and very finely particulate fractions such as soils, sludges, cinders, etc. economically and effectively on an industrial scale. To this end, the fluidised mixture containing the material in the dispersed state is pressurised, using a gas under high pressure, while said gas is expanded rapidly, and a preferably rapid separation between the solid and the fluid phase is subsequently carried out. A plant for carrying out this method of cleaning comprises a reactor (22) to receive the dispersion, having a pulsing device (23) for releasing single pulses of highly pressurised gases into the dispersion, a high-pressure device (24, 25, 26) for supplying the pulsing device with the high-pressure gas, and a solids remover (27) for dispersion discharged from the reactor. As a result, a decontaminated, biologically active and incorporatable soil is obtained, or, for example, deoiled cinder which can be used directly as an additive in the iron-making process. <IMAGE>

Abstract: The present invention relates to an aerosol hair spray package having reduced volatile organic compound emission during the useful life of the package. A hair spray composition (3, 25) is packaged in either a self-propelled aersol hair spray package (1) or a pump spray hair spray package (20) containing a low delivery rate discharge means (6,23). The hair spray composition (3, 25) contains a combination of at least two polymers in weight ratios of 99:1 to 1:99 differing in weight average molecular weight by at least 1.5, one of which is required to have a number average molecular weight of at least 100,000. This blend of polymers combines with the low delivery rate discharge means-0.2-0.38 grams per second for the self-propelled hair spray package (1) and 0.06 to 0.012 grams per pump stroke for the pump spray hair spray package (20)-to provide an atomized hair spray composition having a volume mean particle size of 60+/-12 microns for package (12) and 73+/-13 microns for package (20). These packages are considerably smaller in size than conventional hair spray packages having higher discharge rates, but provide substantially the same number of uses per container as the larger size conventional hair spray packages, thus effecting reduced cost and environmental impact advantages.

Title: Heat exchanger.
Inventor: WALLSTEIN DIETER
IPC: F28F19/00
Filed: 1991-09-25
Abstract: A heat exchanger for cooling hot crude gas containing aggressive components and for heating the pure gas obtained from the crude gas has a housing (1) formed by two lateral walls (2, 3) and upper and lower tubular bottoms (4, 5) . Partitions (8, 9) are linked to the lateral walls (2, 3) in order to form an inner cavity. In the upper and lower tubular bottoms (4, 5) are inserted the ends of a plurality of mutually parallel exchanger tubes (10) that extend parallel to the lateral walls. The hot crude gas flows through the exchanger tubes (10) and the pure gas flows through the housing (1) transversely to the exchanger tubes (10). The invention should ensure that the lateral walls of the heat exchangers are better protected against corrosion. For this purpose, an underpressure is applied to the cavities (6) formed between the lateral walls and the partitions, and the noxious gases of the pure gas that diffuse through the partitions into the cavities are fed by a duct into the stream of pure gas. Alternatively, an overpressure can be applied in the cavities formed between the lateral walls and the partitions.

Abstract: A formwork (1) for surfaces with varying curvature has a formwork skin (2) which can be adjusted with respect to its curvature, bearers (3) supporting the latter and a chord arrangement which acts on the bearers (3) at a distance from the formwork skin (2), is formed by individual chord pieces (4, 5) bridging the bearers (3) and is expediently fastened to the outer sides of the bearers (3) facing away from the formwork skin (2). The adjustment of the curvature of the formwork skin (2) is carried out by changing the effective length of the chord pieces (4, 5) between the bearers (3). The mutually opposite formwork elements are able to be braced with respect to one another by means of formwork tie rods (6). In this arrangement, as chord piece, a cross member (4) acts on a formwork element at at least two bearers (3), the said cross member at the same time being provided as an abutment for the formwork tie rod (6), which is consequently arranged between two bearers and the forces of reaction of which are transferred to the two bearers. The cross member is in this case likewise able to be changed with respect to its effective length by its fastening point being adjustable in the direction of its longitudinal extent and transversely to the orientation of the bearer, so that the cross member (4) both provides an adjustable chord piece when changing the curvature of the formwork skin (2) and absorbs the tensioning forces. <IMAGE>
