Abstract: An improved engine for aeronautical applications includes a forged cylinder block having a drive device rotatably mounted therewithin and a motive device for rotating the drive device, the motive device including two cylinder banks in a V-type configuration and a plurality of cylinders mounted within the cylinder banks for producing power and rotating the drive device. The forged cylinder block further includes a plurality of cylinder cavities formed in the cylinder banks and the upper approximately one-third of each of the cylinder cavities is generally surrounded by a generally toroidal cooling chamber, and the lower approximately two-thirds of each of the cylinder cavities is generally free of any surrounding cooling chambers. Finally, a coolant circulation device in fluid transmission connection with each of the cooling chambers is operative to circulate cooling fluid therethrough whereby the upper approximately one-third of each of the cylinder cavities is cooled by the cooling fluid.

Abstract: A feed supplement for livestock includes, in a feed supplement combination, a quantity of waste product material selected from the group comprising dissolved air floatation product (DAF) and paunch manure and a quantity of an inert dry medium which will not chemically react with the waste product material such as soy hulls, hay, alfalfa, corn and other such dry mediums. The waste product material comprises between one percent (1%) and ninety-nine percent (99%) of the feed supplement combination. The feed supplement combination is then processed through an extrusion process involving the cooking, grinding and mixing of the feed supplement combination under pressure and elevated temperature, wherein the temperature of the feed supplement combination is raised above 250 degrees Fahrenheit to sterilize and dehydrate the feed supplement combination.
