Abstract: A portable party table [1000] for holding hot and cold foods is described. It employs at least two sections [1100, 1500] held together with a hinge [1600] for holding foods. The party table [1000] has folding legs [1111, 1511] and leg supports [1113, 1513] to support the legs. Each section [1100, 1500] has a tapered base [1101, 1501] with a drain hole [1107, 1507] and a drain plug [1109, 1509]. As ice melts it is directed toward the drain holes [1107, 1507]. Electric receptacle [1525] provide electricity for a heating plate. Alternatively, the hinge [1600] is a type which provides spacing between the sections [1100, 1500] to thermally insulate the hot from the cold section. The hinge [1600] may be allowed to slide to provide an insulation gap [1607], or eliminate the gap [1607].

Abstract: An automated liquid dispensing system employs a mechanism which moves a container [1230] relative to a fill tube [1240] to fill the container [1230] with the proper amount of liquid [1131] with a designated amount of foam [1137]. The system [1000] also includes a container dispensing unit [1400] which pre-chills containers [1230] then flips them into a drop tube [1510] to be received by a lift [1550]. Lift [1550] raises the container [1230] to a pouring head [1570] and fills the container [1230] as it lowers container [1230] to properly fill the container [1230] and create a desired amount of foam [1137].

Abstract: A liquid dispenser with an interchangeable head and remote operating mechanism includes: a) an elongated handle member having a proximal end for a user to hold and an opposing distal end, the distal end including a storage compartment; b) a liquid reservoir contained within the storage compartment; c) said liquid reservoir connected to a universal head connector; d) the universal head connector having external exposure at distal end for connection to at least one interchangeable head; e) a pump located in the storage compartment connected to said liquid reservoir; f) remote control means located near the proximal end of the handle member for turning the pump on and off and for operating the pump in a first direction to pump liquid into the liquid supply container and in a second direction for subsequently pumping out of the liquid supply container; and, g) at least one interchangeable head connectable to the universal head connector, selected from the group consisting of a liquid dispensing brush, a liquid di

Abstract: A simulation system [200] models and optimizes parameters for a pulsed liquid slug boring system employing an energetic fluid [7]. The simulation system [200] employs a fluid flow energy unit [251], an exhaust and retention energy unit [253] and a comminuting energy unit [255] to calculate energies of the system. Total energy unit [257] combines these energies. Fluid flow energy unit 251 receives fluid volume and calculates the fluid flow energy. Exhaust and retention energy unit 253 receives input from the exhaust energy volume unit [243] and mission duration unit [211] to determine the exhaust and retention energy. Comminuting energy unit 255 receives hole depth and hole diameter and specific energy of rock to determine the require comminuting energy. The simulation system [200] operates to determine optimum values of design parameters by searching for the minimum energy solution.
