Abstract: The invention is a method of indicating the presence of an impregnant, e.g. an antimicrobial composition, in cloth to provide visual evidence of the continuing activity of the impregnant. The antimicrobial composition in the cloth is activated on contact with a liquid such as water and is ionically bonded to the cloth. Small portions of the impregnated cloth are dyed with an indicator dye which bonds preferentially to the antimicrobial composition so that when the antimicrobial composition is exhausted, the dye will disappear from the cloth. The dye is preferably applied to the cloth in stripes.

The target includes a body having a substantially spherical surface to which a plurality of discrete multi-faceted return reflective elements are fixed. A plurality of guard pegs are interspaced between the reflective elements and extend outward from the surface of the body substantially beyond the outer surface of the reflective elements for protecting the reflecting surfaces from abrasion.

Abstract: An exerciser and tension reliever comprising a pair of compressible members disposed between a pair of flanges, the compressible members being provided with aligned central openings extending throughout the length of the compressible members and a pair of externally threaded bolt members extend into the said central openings. Elements are provided for rotating each of the said bolt members with respect to one another and when the threaded members are so rotated with respect to one another, the compressible members are caused to be compressed until the compressive forces applied to the compressible members are such as to overcome the forces retaining the threaded members in engagement with one another and when this occurs the threads of one of the threaded members will be caused to slip over the next adjacent threads of the other threaded member causing a clicking sound and simultaneously therewith the compressible members will return to their original uncompressed condition.

Abstract: A turret-type hand punch adapted primarily for punching holes in leather, imitation leather, or other plastic material. Means are provided on the punch to receive the cut portions of the leather or the like and to retain the same therein during the punching operation so as to prevent the littering of the area where the punching is taking place, with the punched out pieces of leather and the like.

Abstract: A process for the simultaneous production of metallized ores and a char. A carbonaceous material such as coal is mixed on a weight ratio basis of about 1/2 coal to about 1 iron ore to about 11/2 or more coal to about 1 iron ore. The coal is mixed on a weight ratio basis with the iron ore within the ratios defined above and the mixture subjected to a heat treatment of between 1800.degree. F. to about 2200.degree. F. within a substantially air tight enclosure wherein in oxidizing atmosphere is provided in the upper portion of the enclosure and a reducing atmosphere is maintained about the materials on the floor of the enclosure.
