A multifunction air cleaning system for polluted air which provides a new process for purifying polluted air, self-adapting and insensitive to variations in weather conditions, with simultaneous abatement and without limits of concentrations or volume of air to be treated, of pollutants of chemical nature, such as combustion products or of other chemical-physical transformations, of pollutants of physical nature, contained in air polluted by urban smog and vehicle traffic. It incorporates air suction means (2), - an oxidation chamber (19), a catalyst bed (20), a mixing chamber (1) for polluted air and oxidized air, a mist reactor (3), a sterilizer (11), a hydrodynamic dehumidifier (12), a dry reactor (14), in which said catalyst bed (20) is arranged. It can be conveniently installed both inside tunnels and in the open air.

The invention relates to the automated cleaning of paint buckets (2).In a device intended for this purpose the curled mouth rims (6) of the buckets are pushed slidingly one by one into the teeth (22,23) of a lifting fork (21), tilted and positioned in upside down position at the location of a scraping station (12), where paint residues are removed from the inner surface by scraping. A thus cleaned bucket is then transported in upside down position to a flushing station (17) where the last paint residues are removed by flushing and spraying clean. The thus cleaned buckets are finally tilted back to their upright position and stacked onto each other in nested form.

A method and apparatus for cleaning and conditioning a fabric (12) in which pressurized fluid is directed into a restricted and diminishing passageway (24) formed by the fabric (12) and a member (20) forming an extended nip therewith so that the fluid is forced through the fabric (12).

Device (10) for stabilizing workpieces (20, 20~) during cleaning comprises first stabilizing units (50) extending parallel to each other in a first direction (R) and arranged at a distance d from the workpieces during cleaning. An independent claim is also included for a method for stabilizing workpieces during cleaning using the above device. Preferred Features: The first stabilizing units are made from a material selected from plastic, aluminum, steel, iron, plastic fibers, natural fibers and carbon fibers. The distance d is 0.1-50 mm, preferably 1-10 mm, especially 1-3 mm.

The present invention relates to detergents and rinse agents for machine dishwashing and to supply forms which combine detergent and rinse agent containing certain polymers in a single product comprising at least one polymer with cationic monomer units and at least one anionic polymer modified with phosphorus- and/or sulfur-containing groups, characterized in that the pH value of a 1% by weight solution of the anionic polymer in distilled water at 20° C. is less than pH 6.

The invention relates to a process for the preparation of a detergent containing one or more compounds having the formula RCONH(C₂H₄O)nCH₂COOH and/or salts thereof, where R represents a linear or branched aliphatic hydrocarbon group with 5-21 carbon atoms and n is a number from 1-20, by amidating, ethoxylating and carboxymethylating one or more fatty acids having the formula RCOOH and, if so desired, converting all or part of the ether carboxylic acid obtained to a salt thereof, characterised in that an oil or fat is started from and that this oil or fat is aminolysed in the presence of an alkali(ne earth) metal and the reaction mixture obtained is in the usual manner ethoxylayed, carboxymethylated and, if desired, converted in whole or in part to a salt.

An ionic surfactant-based protomicroemulsion or microemulsion composition contains, by weight, at least about 20% of an ionic surfactant system, from about 0.1% to about 50% of a low water-soluble compound, and from about 5% to about 79% of a solvent, and is substantially free of low water-soluble oils. The protomicroemulsion forms a microemulsion when diluted from about 10% to about 99% with water.

The water removal device has a line (4) carrying water from a pump (2) to an outlet (3) and containing at least one container, a connecting pipe and an elbow union pipe. The line contains a body or a one-piece part formed by the container and at least one of the other two elements. The assembly formed by the container and connecting pipe is connected to the elbow union pipe directly or via a connecting part.

The system performs denitrification on the water obtained from drainage of a pond (60) where water plants (50) are grown. The drainage is arranged at the root area of the water plants. A water supply is provided in the pond. The drainage removes the water from the pond for denitrification. A pump is used for collecting water from the pond.

It is a tank (1) for liquids complete with base valve (23) with rapid opening and closure feature rendered operational by positioning on, or by lifting the tank (1) from the support cup (2) which connects with the discharge element (31), this support (3) being supported by the handle projection of the floor-washing appliance itself. This type of tank (1) and relative support cup (2) complete with discharge element (31) makes it possible to either replace or exchange the tank for others full of floor washing liquid.
