Abstract: The present disclosure is directed toward implementations of internal combustion engines. The disclosure describes various embodiments of internal combustion engines where most of the internal elements rotate. Such engines allow for more efficient transfer of the energy created by combustion to the motive components of a vehicle such as wheels or propellers. One specific embodiment includes a rotating cylinder with a single piston which both reciprocates and rotates. The rotating motion of the piston is transferred to the cylinder, which in turn is connected to a driveshaft. Various embodiments of the invention employ differing numbers and configurations of pistons. All embodiments have the advantage of decreasing engine volume and increasing efficiency over traditional internal combustion engines.

Abstract: The portable beverage dispensing system disclosed is a portable cooler for dispensing bulk beverages, such as beer in various sized kegs, for example, comprising: a lower tub component that defines an open interior region for removably receiving the keg(s); a hollow upper component that removably attaches to the lower tub component and surrounds the upper portion of the keg(s); and a table top that removably attaches to the hollow upper component and which may furthermore have aperture(s) that allow standard beverage dispensing components to pass through and attach to the table top for dispensing of beverages. The portable beverage dispensing system may also comprise: a wheel attachment apparatus, connected to the lower tub in a fixed or removable manner; and a handle apparatus, connected to the table top in a fixed or removable manner; both of which allow portability of the portable beverage dispensing system.
