The present invention relates to a portable storage and locking apparatus that permits towing hitches and hitch-mountable accessories to be stored and locked to trailers, vehicles, buildings and other locations having exposed frames, beams, channels or other structures and storage locations. The apparatus does not require tools or hardware to mount and uses a pair of spaced-apart side plates joined to form a u-shaped mount that slides over a frame. The side plates have at least one pair of square-shaped aligned holes near the open ends, which extend past the frame and are configured to insert a towing hitch or accessory. With the apparatus over a frame, and a towing hitch or accessory inserted in the square holes, the apparatus is effectively secured to the frame and cannot be removed. A trailer hitch locking pin may be used to lock the hitch or accessory to the apparatus, and therefore to the frame.

The method and two devices provide for the underground connection of pipe with minimal disruption of the surrounding landscape. A main pipe is cleaned by a surface preparation tool designed to access the main pipe through a small hole. An adaptor is attached to a second pipe, and then placed in a clamping device designed to access the main pipe and clamp the adaptor thereto through the small hole. Electricity is passed through the adaptor, thereby softening the plastic so that this softening and the pressure of the clamp secures the adaptor to the main pipe. The main pipe is then pierced by the adaptor's tapping tee.

A vacuum excavation system is provided in which a vacuum is generated for withdrawing dirt, water or other material from a vacuum excavation site, and whereby such material is delivered to a containment structure, preferably of the hopper type having a discharge. A valve is provided for the vacuum, such that actuation of the valve interrupts the vacuum, whereby material pickup may be discontinued and/or material may be discharged from the containment structure. Preferably the vacuum-controlling valve exists in a conduit between the situs of vacuum generation and a containment structure. The valve will preferably be controlled by a pneumatic/electrical control for operation of the same. The excavation system is preferably vehicle-mounted, with the same motor that drives the vehicle also driving an air compressor for operating a pneumatic tool as well as driving the vacuum generator.

Vacuum excavation system

In a material transfer system, material from an excavation is drawn into a vessel by suction from a vacuum source. The vessel has discharge flaps at the bottom that are held closed by the suction. When the weight of the material in the vessel reaches a predetermined value, the flaps open and the material is discharged from the vessel. After the discharge, counterweights almost close the flaps and the suction seals the discharge flaps so that additional material is drawn into the vessel. The vessel includes a vibratory section and has sides that slope outwardly from top to bottom. The material entering the vessel contacts the vibratory section at a predetermined angle and is redirected to the discharge flaps without any caking on the vessel walls. The opening through the discharge flaps is larger than the inlet through which the material enters the vessel so that objects entering the vessel are discharged.
