Abstract: A mobile pavement replacement system (MPRS) is provided for forcibly drawing a flexibly-supported, acute-angled wedge under an existing stretch of a predetermined width of reinforced pavement to initiate removal thereof from the ground below. Gravity-assisted impact hammers apply downward blows of a controlled magnitude and at a predetermined rate onto an upper surface of the reinforced pavement, to crack the same across the entire width thereof over the wedge being driven therebelow. The wedge is flexibly supported, with a predetermined amount of elasticity in the up-and-down direction, so that it essentially "floats" and facilitates absorption of the impact forces by the reinforced pavement to be cracked thereby. Cracked reinforced pavement is subjected to further blows by a hammer coacting with a set of bars transverse thereto, to forcibly render a bulk component of the reinforced pavement into small pieces separated from reinforcement material contained therein.

Abstract: A feed delivery system for individualized rations for specific livestock includes a programmable controller responsive to status of the livestock. Individual elements of a feed ration are combined to meet the requirements of a specific animal and delivered only to that animal. Plural delivery containers may each be loaded with different rations for different animals. The inventive concept may also be used for delivery of food to hospital patients having different dietary requirements, for delivery of different components to various worksites in a manufacturing process, or for delivery of chemicals to a chemical process.
