Abstract: A stackable and nestable support apparatus the stackable and nestable support apparatus of the present invention includes multiple support elements that are stackable to provide for support base of varied elevations. In a stacked, supporting position, one or more of the support elements are selected for emplacement between a foot of a leveling jack utilized to level the recreational vehicle (RV). The number and orientation of the one or more support elements are selected based on a needed vertical support elevation between the foot of the leveling jack and the terrain T in which the RV is emplaced. The multiple support elements are also nestable to reduce storage space when not in use.

Abstract: An improved wheel chock system for preventing excessive movement of tires, wheels, and other rollable objects, having two cooperating members connected via a connector permitting pivotal movement by at least one of the cooperating members about the connector. The cooperating members each have a handle at their one end for actuating wheel chocks retained at their other end throughout a range between a fully open condition where the wheel chocks are spaced away from each other, and a fully closed condition where the wheel chocks are spaced adjacent to one another.

Abstract: A multi-component liquid dairy product dispensing system is provided which preferably utilizes an ultrasonic mixing chamber to essentially instantaneously combine and reconstitute liquid dairy product streams of various concentrations, with or without water, into a single homogeneous final liquid dairy product. Depending on the ratio of the liquid dairy products, a resultant liquid dairy product is provided which possess the same quality and attributes of the traditional liquid dairy products known by consumers, and can meet the regulatory standards for identification for various milk and cream products with respect to milk solids and fat content percentages. The liquid dairy product streams are preferably aseptic products in order to increase their shelf-life and stability. The resultant liquid dairy product dispensing system provides a system which is capable of rapidly providing a variety of liquid dairy products.
