An improvement in fluid-bed oxychlorination methods comprising in combination a generally cup-shaped container and an inverted generally cone-shaped gas distributor having a truncated apex the section of truncation defining a generally circular or polygonal opening, the lip portion of the container fitting against the similarly-shaped opening of the distributor.

Chlorination method

An apparatus for the distribution of gas in a fluidized bed reactor comprises in combination a generally cup-shaped container and an inverted generally cone-shaped gas distributor having a truncated apex the section of truncation defining a generally circular or polygonal opening, the lip portion of the container fitting against the similarly-shaped opening of the distributor.

Gas distributor apparatus for fluidized bed reactor

Vinyl plastisols are fused to heat-sensitive primary backings and facing yarns integral therewith and expanded thereon by the application of a heating medium in the form of high velocity steam or a high velocity gas. Although the temperature of the heating medium is above the softening point of the heat-sensitive primary backing, the velocity of the heating medium and the angle at which it is directed against the plastisol-coated, heat-sensitive primary backing results in fusion and expansion of the vinyl plastisol on the heat-sensitive primary backing without damage to the backing material or facing materials associated therewith.
