Abstract: A method for the regeneration of sulfur containing cerium compounds formed by the desulfurization of fluid materials containing sulfur with cerium oxide back to its original form, CeO.sub.2, wherein the sulfur containing cerium compounds are removed from contact with the fluid material containing sulfur; the temperature of the sulfur containing cerium compounds is raised above the temperature at which cerium sulfate dissociates; and the sulfur containing cerium compounds whose temperature is above the temperature at which cerium sulfate dissociates is exposed to an oxidizing atmosphere.

Abstract: An arm rest for supporting an extended upper arm is provided in which the arm rest can be adjusted to accommodate the height of the user. Particularly adapted for hunting, the arm rest attaches to the belt of a hunter and extends upward to an arm pad upon which the hunter rests his upper arm while aiming at his target. The length of the arm rest as well as its angular position relative to the hunter can be easily adjusted to provide the most comfortable setting for the hunter. When not in use, the arm rest can be recessed and hang from the waist so as to not interfere with walking about. Alternatively, the arm rest can pivot about its base and be secured in a rearward direction, preventing its entanglement in brush.

Abstract: An improved method and apparatus for recovery of waste heat of the type having a first heat exchanger which transfers heat to a working fluid and a second heat exchanger which transfers heat from the working fluid is disclosed. The improvement comprises the provision of at least one storage tank for the working fluid having a volume calculated by the flow rate of the working fluid multiplied by a time difference between the time in which the combusiton chamber has its peak fuel requirement and a next subsequent time at which a maximum amount of waste heat is available to the combustion chamber. This minimum capacity can be obtained by the provision of one tank or several tanks having a combined storage capacity which meets or exceeds the calculated volume. Preferably the storage tank, or combination of storage tanks, is positioned between the heat exchangers so as to receive heated working fluid from the first heat exchanger and provide heated working fluid to the second heat exchanger.

Abstract: An electrical buss bar assembly is provided in which an elongate conductor member having at least one generally flat surface with two spaced generally parallel channels having an opening through the flat surface narrower than a major section of the channel parallel to the flat surface and separated by a riser member extending above said surface are provided with at least one connector module made up of a top member with two depending legs bent inwardly at the end remote from the top member and terminating adjacent the riser member and having a foot member on each slidably engaged in the parallel channels through said opening, and clamp means in the top member acting to exert pressure on a wire inserted between the legs and on the riser to fix the wire in the connector module and the connector module in tight conductive relation on the conductor member.
