Abstract: A system for reducing the emissions produced by an engine affixed to a body during operation and reducing noise and vibration. The present invention is particularly related to a small form factor active/passive Diesel Particulate Filter system having an exhaust backpressure sensor, a heating element, a Diesel Oxidation Catalyst, a power relay switch, a filter and an electronic control unit for controlling the heating element based on backpressure detected by the sensor.

Abstract: The present invention is generally related to providing auxiliary power to long-haul trucks and similar types of transportation vehicles, and more particularly related to an easily installed and maintained auxiliary power unit that provides operational levels of electrical power and HVAC services while simultaneously driving a hydraulic system through an incorporated hydraulic pump assembly.

Abstract: A process for renewing a cylinder head, preferably a cast aluminum water cooled cylinder head from a used condition to a rebuilt condition suitable for reuse. In a qualifying stage the used cylinder head is stripped of removable parts, inspected, heat treated for cleaning and stress relieving purposes, and then pressure tested to detect leaks through cracks or excessive porosity. If cracks are located, the cylinder head passes through a reconstruction stage wherein cracked areas are removed and replaced by welded material, recontoured and preferably again pressure tested. A cylinder head which did not need reconstruction (or after reconstruction) then passes to the rebuilding stage where it is essentially machined and component parts replaced. Included in the rebuilding stage is a line-boring and surface gasket facing procedure for eliminating the adverse effects of warpage and a vacuum impregnation step to seal the pores of the cylinder head.

Abstract: A heat-resistant bib overall for use by a fireman includes a lower trouser portion and an upper bib portion, the lower trouser portion providing right and left outer (side) seams, the bib portion including separate right front and left front and rear bib sections, said bib sections being continuously sewn along their bottom edges to a high waistband formed by a hem along the upper edge of the trouser portion, the rear bib portion extending forwardly to the respective right and left outer (side) seams and the right and left front bib sections extending rearwardly past the respective right and left outer (side) seams, such that the respective front bib sections will overlap the rear bib section along the opposite sides of the bib overall.
