Abstract: A conduit arrangement for a tilt cylinder of a bulldozer having a track frame and a push arm connected to the track frame for operating the blade of the bulldozer and including a trunnion for pivotally connecting the push arm to the track frame. A pair of spaced fluid passages are provided through the trunnion. A first pair of conduits have one end coupled to the tilt cylinder and the other end connected to the fluid passages. The first pair of conduits pass through an internal bore provided through the push arm. The inboard end of the trunnion extends into the interior of the track frame. The fluid passages extend through the trunnion into the interior of the track frame. A second pair of conduits pass inwardly through the track frame towards the main frame of the bulldozer. One end of each of the second pair of conduits is connected to the fluid passages and the other end extends into the bulldozer main frame. The track frame is spaced from the bulldozer main frame.

Abstract: A sewage treatment device [10] is disclosed for use with a toilet [12] having a water flush input [16] and a sewage output [22]. The invention incorporates a treatment tank [56] connected for receiving the sewage from the sewage output [22] of the toilet. A disinfectant holding tank [58] is included for holding a disinfectant such as conventional household bleach. A mascerator blade [74] is disposed within the treatment tank [56] for mascerating the sewage to reduce the size of the particulate matter within the treatment tank [56]. An electric motor rotates the mascerator blade [74] and simultaneously pumps a disinfectant from the disinfectant holding tank [58] to the treatment tank [56]. A discharge pump [86] discharges the treated sewage from the treatment tank [56]. A control senses the level of the sewage in the sewage treatment tank and controls the sequence of operation of the mascerator blade [74] and the discharge pump [86].
