Abstract: A shoe sizer capable of measuring the feet of men or women and designed to be readily shipped by mail, comprising a base having a flat upper surface, an elongate slot, and a plurality of mounting recesses; a vertically-projecting heel portion having a mounting lug for engaging one of the mounting recesses and designed to accurately and consistently position a heel on a selected portion of said base; a vertically projecting stopping member to aid in the proper positioning of the foot; a foot width indicator which is slidably engaged in the elongate slot; and a sizing grid placed on the upper surface of the base so as to accurately and consistently measure the size and width of either men's or women's feet.

Abstract: The invention relates to a process for working additives into polymers, in which a mixture of thermoplastics with additives is heated to a temperature sufficient for the melting process, with the possible introduction of an expanding agent into the melt in which the expanding agent is homogenized, the melt being cooled if necessary to a temperature at which it can be extruded in the form of a foam plastic, the additives being adsorbed on a polymer flocculent matrix having a sufficient specific area, due to having a density of up to 0.6 g/cm.sup.3 and 15 to 99% of open foam cells and being of the same or different polymer composition as the basic polymer.
