Abstract: The present invention describes chemicals that have certain properties which cause them to be free or substantially free from endocrine disruptive activity. As a result, the chemicals are useful in producing plastic materials that may be used in products which are exposed to individuals in which endocrine disruptive activity is particularly disadvantageous, such as baby bottles, baby toys, food containers, medical containers, animal cages and medical products. The chemicals may also be useful as food additives which are used in food products that are ingested by individuals in which endocrine disruptive activity is particularly disadvantageous, such as newborns or the physically infirm.

Abstract: A motor includes a plurality of linearly activated pistons, positioned radially around an axis, which are selectively and sequentially biased against on offset element to produce rotation of a rotatable element about the axis. The motor further includes an power source, which may be electrical, pneumatic or hydraulic and a structure for supporting the pistons, the offset element and the rotational element, and providing direction of a desired motion.

Abstract: A heat engine includes a plurality of heating side expansion chambers and cooling side expansion chambers, positioned on opposite sides of an axis, for providing rotation of an apparatus about its axis when the fluids inside the chambers expand and contract on the same side and plane of a rotational axis. This is accomplished by, shifting the weight of fluids off-balance, or a weight, when the fluid, expands and exerts a pressure on an elastic wall inside an expansion chamber and contracts and reduces pressure on an elastic wall inside an expansion chamber, or by moving an element or ring, through actuators, when fluids expand and contract in the expansion chambers. The engine further includes a heat source and a structure for supporting the expansion chambers and heat source, and providing direction of a desired motion.
