A process of making a foamed thermoplastic elastomer is disclosed, and the foam thus produced. The thermoplastic elastomers, which are blends of 90 to 10 parts of rubber and 10 to 90 parts of crystalline polyolefin plastic, are melted, admixed with water under pressure, and released to atmospheric pressure. The resultant foam has good cell structure and low density, and a high percentage of closed...

Stable, low-viscosity dispersions of polysiloxanes containing amino or amido groups can be obtained, even at comparatively high concentrations and/or pH values, by adding a product of the formula R1-CH(X)-Y-O-R2 (R1 is H, CH3; X=OH, NH2; R2=C-C4-alkyl, unsubstituted or substituted by OH or OR3; R3=C1-C4-alkyl, unsubstituted or substituted by OH) to the dispersions. The dispersions are suitable for...

Combined structure for the multi-staged biological cleansing of waste water containing organic dirt material, comprises three concentric ring chambers (5, 7, 12) formed by ring shaped intermediate walls (4, 13). The waste water in the inner chamber (5) is moved by a circulating unit (9), and the middle ring chamber (7) also contains a circulating unit (11) and is used for the anoxic denitrificatio...

Sediments are treated to give a material which can be deposited on a waste dump in a long term environmentally tolerated manner, or an environmentally tolerated building material, in particular for waterproofing coatings, the contaminated sediments from water to be conditioned being dewatered to a water content of at most about 140% relative to their dry weight; the sediments from water dewatered ...

A process for electrolytically producing an aqueous solution of chloric acid and alkali metal chlorate in an electrolytic cell having an anode compartment, a cathode compartment, and at least one ion exchange compartment between the anode compartment and the cathode compartment. The process includes the steps of feeding an aqueous solution of an alkali metal chlorate to the ion exchange compartmen...

The method for applying granules to a coated asphalt sheet includes accumulating granules in a nozzle having an opening at the bottom for discharging the granules onto the coated asphalt sheet, and changing the air pressure in a buffer chamber positioned in communication with the accumulation of granules to control the flow of granules through the opening.

Redispersible core-shell polymers in powder form (I) comprise: (a) a core polymer of, (a1) 80 - 100 wt. % acrylate monomers, opt. combined with styrene monomers, and (a2) 0 - 20 wt. % unsatd. sulphonic acid cpds.; and (b) a shell polymer of, (b1) 60 - 95 wt. % monomers as in (a1), and (b2) 5 - 40 wt % monomers as in (a2), with a higher content of sulphonic acid monomer (a2/b2) in the shell than in...

Aqueous emulsions of grafted polymer compositions are provided. The grafted component of these compositions has two or more polymeric substituents. The aqueous emulsions of grafted polymer compositions are particularly useful as cement modifiers.

This invention relates to a method of detecting a site of infection or inflammation, and a method for treating such infection or inflammation, in an individual by administering to the individual a diagnostically or therapeutically effective amount of detectably labeled, therapeutic, or therapeutically-conjugated, chemotactic peptide that accumulates substantially at the infected or inflamed site, ...

The invention relates to the use of a novel set retarder for the wet spraying process, the setting time being extended and, for example, being delayed to such an extent that the spraying material can be delivered from a ready-mixed concrete factory to the building site and, at the latter, remains usable for several days, but can be caused to set and rapidly harden at any time by addition of a sett...

A body conforming absorbent article, such as a sanitary napkin, is disclosed which has preferential bending zones and a structural zone. The bending zones cause the article to preferentially bend at locations anterior and posterior to the labia majora so as to keep a relatively planar configuration in the perineal area. The structural zone is resistant to wet collapse so that the central portion o...
