Abstract: A hitch assembly for attaching a following trailer to a leading trailer and preventing lateral pivoting of the hitch assembly with respect to the leading trailer includes a dolly which laterally pivotally attaches to a hitch of the leading trailer. The dolly trails the leading trailer and has a fifth wheel hitch for attaching to a following trailer. A stabilizer on the dolly is deployable near a rear end of the leading trailer such that lateral pivoting of the dolly with respect to the leading trailer is limited or entirely obstructed. The inhibiting action of the stabilizer facilitates accurate alignment of the fifth wheel hitch with the following trailer.

Abstract: A wastewater tertiary media filtration system capable of enhancing filtration performance while including backwashing capabilities that eliminate turbidity spikes by using compressed fluid injected to the interior of submerged includes a filter tank having an inlet and an outlet with a plurality of pile cloth media filter disks disposed in generally parallel relation between the inlet and outlet. Each filter disk preferably includes opposing filter panels disposed in generally parallel spaced relation and supported by a frame. The filter disks may be angularly disposed at approximately 55-degrees relative to horizontal so as to maximize settlement velocity in accordance with the advantages of inclined plate technology. Backwashing is primarily accomplished by injecting compressed fluid (such as air) to the interior of each filter disk assembly whereby accumulated solids are blown off of the cloth filter media by reverse flow.

Abstract: Logging-while-drilling apparatus and methodologies for measuring streaming potential in an earth formation are provided. The apparatus and methodologies can be utilized to find information relevant to the drilling operations. In particular, since the streaming potential measurement relates directly to fluid flow, the streaming potential measurements can be used to track flow of fluids in the formation. In turn, this information may be used to find information relevant to the drilling operations, such as under-balanced drilling conditions, abnormal formation pressures, open fractures, the permeability of the formation, and formation pressure.
