Abstract: A hide or pelt processing agent suitable for use in leather treating compositions comprising a N-alkyl-heterocyclic amide having C.sub.6 to C.sub.18 alkyl substitution on the hetero-nitrogen atom; such as, for example N-octyl-2-pyrrolidone, N-dodecyl-2-pyrrolidone, N-cocoalkyl-2-pyrrolidone and N-tallowalkyl-2-pyrrolidone, employed in an amount between about 0.01 and about 20% by weight based on the total composition of a standard leather treating solution, suspension or emulsion.The present composition containing one or more of the N-heterocyclic amides can be applied in various curing, tanning and finishing stages of leather treatment to produce processed hides and pelts of improved dyeability, flexibility and moisture content.

Abstract: The present invention relates to a timepiece for indicating time by distinguishable colors, each corresponding to a standard unit of a time period. The units of the time period are represented by a plurality of uniform sections each differentiated by a distinguishable color and carried in a display area of a substantially flat annular member, preferably having a thickness or depth not more than 1/4 its diameter. The proper unit of the time period is indicated by reference means which may be a separate indicator or which may be carried on a separate cover member positioned above the display portion or area so as to indicate each of the distinguishable colors of the time period successively upon uniform, incremental and rotational movement between the reference means and the display portion carried by the annular member. The successive uniform rotational movement between each section and the point of reference is effected by a standard timepiece driving means.
