Abstract: A fabric is superficially dyed by stamping and then subjected to abrasion to produce a feltlike appearance and a simultaneous mutation in coloring.

Abstract: A multiply durable laminated cookware unit includes components having a ferrous steel core ply roll plated with second and third aluminum plies which are softer and anodic relative to the core ply and which are bonded to the core ply under pressure so as to provide exposed surfaces on the unit which exhibit the properties of rolled solid aluminum sheets. The exposed edge of the steel core can be protected by drawing at least one of the softer anodic aluminum cover sheets such that it extends beyond the harder steel core and the extended portion of the aluminum sheet is folded over the steel core to seal the edge end of the steel core therebeneath.

Abstract: A drive belt assembly for snowmobiles. The assembly includes an endless drive belt, which extends substantially across the entire width of the rear portion of the snowmobile, and is longitudinally and drivably supported on the snowmobile body. First and second sets of transversely and alternately positioned and spaced drive cleats are securely mounted on the outer surface of the drive belt. Each of the cleats has a first end portion which is adjacent one of the lateral edges of the belt, and a second end portion, which is spaced inwardly from the other edge of the drive belt. Surface portions are defined on the outer surface of the track longitudinally between each of the first end portions of one set of the drive cleats, and transversely between the second end portion of each of the other set of cleats, and the other edge of the drive belt. Flexible, unitary, lugs or projections extend from the outer surface portion.

Abstract: A sterilizable, peelable pouch or tray for medical and surgical equipment. The pouch comprises two superimposed sheets, preferably of autoclavable plastic, interconnected by an edge-strip of folded-over plastic affixed to the exterior surfaces of the sheet. The strip extends around at least a portion of the perimeter of the sheet edges and serves to provide a readily separable interconnection between the sheets. The sheets are separated by merely peeling one sheet back, thereby ripping the folded-over strip at the juncture between the two sheets. The tray assembly is similar with an upper plastic sheet removably, peelably affixed to a lower formed plastic cardboard or metal tray by the perimeter strips.
