In the manufacture of insulating shells formed by a felt of mineral fibers wound around a mandrel, main pressing elements intervene as soon as the winding begins and remain in contact with the surface of the shell during the entire winding phase. Auxiliary pressing elements intervent only when the shell, during shaping, has reached a given outside diameter of, for example, 200 mm. The process appl...

Improved durability and water repellency are provided to porous substrates by the use of a novel penetrating treatment composition comprising (A) C10 to C22 alkyl acrylate(s) or methacrylate(s) which are non-oxidizing and polymerizable to form homopolymers having a glass transition temperature of about 0 DEG C or less and (B) autoxidative compound(s) which function as polymerization initiator-oxyg...

A method of heating, for instance sterilization or pasteurization of food packed in microwave transparent packaging material and where the heat treatment is a continuous one by transporting the product through a processing channel. Microwaves of different strength are applied for heating the product. Portions of the product are heated quickly by the microwaves following curve (10)(10'''), other po...

In the particular embodiments of the waste water treatment system described in the specification, a waste water treatment basin has spaced-apart, moving aerator chains extending across the basin in a direction transverse to the flow of waste water through the basin. When an aerator chain is provided with air, bottom aerators suspended from the chain adjacent to the bottom of the basin move with re...
