Abstract: New and improved spill containment devices and methods, for use primarily by the railroads, are provided in one or more lidded catch pans positionable generally around and under a transportation container for collecting and containing spilled or dripping chemical materials. A preferred spill containment apparatus comprises a combination of three catch pans positionable along a railroad siding including an inboard pan disposed between the rails and two outboard pans extending outwardly adjacent and alongside the rails and the inboard pan. The outboard pans have sectional lids that swing back over the railroad rails. This not only protects the area from splashing caused by heavy dropping in the big center pan, but also ensures that drips from above do not land on the rails or the gap between the inboard pan and the rails. When not in use, these sloped sectional lids divert dirt and rainwater away from the outboard receptacle or collecting basin portions of each outer pan.

Abstract: This doll, or mannequin, features a relatively rigid core with an expandable flexible covering and inflation mechanism in order to expand the flexible covering to simulate weight gain or muscular development. The inflation mechanism may include a valve to slowly release accumulated pressure to simulate weight loss. The flexible covering, simulating a person's skin, may be formed integrally upon the core or may be placed upon the core as a close-fitting enclosure. The muscle gain doll features nonexpanding bands attached to the flexible covering to simulate muscular definition. Such a doll may be used with essentially non-stretchable clothing to simulate a person growing larger relative to their clothing and the unseemly appearance resulting therefrom.
