Abstract: A hand covering is provided which is formed of a finger portion and a lower hand portion. The lower hand portion is formed from a one piece back and palm part, or in the alternative a two piece back and palm part; each lower hand portion includes integral thumb portions. After sealing the lower hand portion in the flat, the lower hand portion is rotated prior to sealing it to the finger portion. The rotation positions the thumb portion in working relationship with, or in opposition to, the finger portion and provides that no more than two seams intersect at a joint.

Abstract: A heat exchanger system exhibits an improved coefficient of heat transfer over a conventional convection heat exchanger while maintaining the beneficial high temperature driving force of conventional convection heat exchanger. A plurality of heat extraction means are provided in heat flow communication with a plurality of shallow beds of particulate matter, which beds are fluidized by a heat-laden gas stream.A method for extracting heat from a heat-laden gas stream is also disclosed.
