Abstract: A system designed the efficient separation, storage, loading, unloading and transportation of recyclable materials such as paper, glass, tin cans, plastic containers, aluminum containers, etc. The major component of the system is a container that is generally box-shaped to allow the containers to be closely stacked in rows. Each container has a slot in the top edge to provide for support of the container on a collection rail bar and support frame system which allows the containers to be efficiently grouped together and thereby provide storage for all classes of materials recycled at a single geographical location. The collection rail system of the invention can be economically adapted to many different types of stationary or motorized transport systems, enabling them to become recyclable material collections systems.

Abstract: An accessory for weightlifting equipment that serves as a mechanical training partner for the weightlifter. The accessory is an electrically-powered, mechanically-driven device that provides a positive assist to enable the lifter to keep lifting even after muscle fatigue or failure. The accessory also provides a negative assist by applying more force as the weight is lowered. Both positive and negative assists are under full control of the lifter using foot or hand controls. The accessory also acts as a safety device which can control the weight if the lifter has problems or feels injured during a positive lift.
