Abstract: The present invention is directed to an apparatus for engaging and lifting the end of a hitch resting on the ground. The apparatus is particularly useful when attached to a yard tractor used for moving trailers or trailer dollys about a parking yard. The apparatus includes a rigid member pivotally attached to a frame attached to the yard tractor. The free end of the rigid member has a plate for scooping under the end of the hitch. A hydraulic actuator remotely rotates a pin into engagement with the end of the hitch. Another actuator pivots the rigid member upwardly to lift the end of the hitch for subsequent movement of the trailer or dolly.

Abstract: An evaporator apparatus (10) and method for converting a contaminated fluid including mostly water and water soluble substances into a vapor and a residue. Apparatus (10) includes a container (11) for retaining the fluid. A heat source (17) is utilized for supplying heat to evaporate the fluid. A flue assembly (18) positioned in the fluid conveys the heat from the heat source (17) through the fluid. A draft mechanism (20) draws off the resulting vapors as they are formed.
