Abstract: A method of treating a material derived from recovery and shredding, the material comprising a mixture of polypropylene and polyethylene, wherein the material is mixed with 1% to 5% by weight of copolymer of ethylene-?-olefin type.

Abstract: Apparatus for measuring axial bending or tensile stresses on a rod (1).A ring (10) carries at least one sensor or transducer (15). A ring (11), parallel to the ring (10), serves as a magnetic target. The rings are formed by two substantially semicircular, dismantlable halves. The measurement consists of estimating the width of the gap (12) between the rings (10 and 11). The sensors (15) can be of the magnetic reluctance type.Application to the measurement of stresses in sliding rods of certain safety taps, cocks or valves.

Abstract: This invention is concerned with a novel antacid composition, said composition comprising, in association with a physiologically acceptable excipient, a pharmaceutically effective amount of a mixture of(a) an Al-containing material which normally adheres to the gastrointestinal mucous membrane, as a first pharmaceutically active component, and(b) a Mg-containing material which normally does not adhere to the gastrointestinal mucous membrane, as a second pharmaceutically active component,wherein the weight ratio of Al in said Al-containing material to Mg in said Mg-containing material is 5.1:1 to 7.0:1.Said composition is particularly useful in the treatment of dyspepsia.
