The apparatus further includes a drive for vibrating each accelerometer to produce output signals and a signal processor for deriving from th...

The invention relates to a method for purifying aqueous solutions containing at least one impurity element from the group consisting of arsenic, phosphorus, mercury and other heavy metals and solid matter by precipitation in at least two stages with the aid of precipitation reagents possessing ions capable of forming not-readily dissolved hydroxide precipitate. In accordance with the invention the...

A method of making a foamed, polyester resin comprises mixing a liquid unsaturated polyester composition, with a liquid borohydride blowing agent which is a liquid borohydride complex, a borohydride complex in organic liquid medium or a borohydride salt dispersed in an organic liquid medium, which medium is at least substantially non-reactive with the borohydride salt. The resulting mixture is per...

In the continuous production of laminates, especially laminated building boards, one or more base sheets impregnated with phenoplast/aminoplast resin mixture in the presence of acid donor curing agents are pressed together at an elevated curing temperature with decorative sheets impregnated with aminoplast resin in the presence of acid donor curing agents.

Disclosed is a method of coating a substrate comprising the steps of (A) coating the substrate with one or more applications of a basecoating composition containing (1) an organic film-forming resin, (2) substantially colorless, substantially inorganic microparticles stably dispersed in the basecoating composition, (3) a solvent system for the film-forming resin, and (3) pigment particles to form ...

The hip joint socket is provided with a peripheral edge or flange in which a plurality of bores are formed. Each bore narrows conically from one side of the peripheral edge towards the free surface of the socket to provide outflow paths for excess bone cement which is displaced during implanting of the socket in a pelvis. The construction in the bores also permits the excess cement to harden into ...
