Abstract: A head covering is in the form of a visor-like cap having an upper band or head-encircling portion with a wire reinforcing member around its upper edge and a visor extending downwardly from the band which includes a crescent-shaped section and a wire reinforcing member embedded in the outer peripheral edge of the crescent-shaped section so as to cause the cap to assume the desired configuration when worn and when not worn to permit it to be coiled into a compact package for storage purposes.

Abstract: A collapsible head covering is in the form of a visor-like cap having the usual head-encircling portion, and a visor or bill extends from the head-encircling portion which includes a normally shapeless crescent-shaped section and a wire-like reinforcing member embedded in the outer peripheral edge of the crescent-shaped section so as to cause the visor to assume a generally convex cross-sectional configuration when worn and can be collapsed by twisting the visor into a coiled circular configuration for storage purposes.

Abstract: An economical procedure for the recovery of platinum from a spent catalyst involves subjecting the catalyst to fluorination with elementary fluorine or a mixture thereof with hydrogen fluoride at a temperature ranging from 100.degree.-600.degree. C. The resultant platinum fluoride is then converted to platinum in elemental form.
Abstract translation: 从废催化剂中回收铂的经济方法包括在100℃-600℃的温度范围内使催化剂与氟化氢在基础氟或其混合物中进行氟化。然后将所得的氟化铂转化成铂 元素形式。
