Abstract: An apparatus for filtering fluid has a container, a platform positioned in the interior volume of the container in a location above a bottom of the container, and a bag filter extending through a hole in the platform. The bag filter has an inlet and an outlet. The inlet is positioned at or above a top surface of the platform and an outlet positioned below the top surface of the platform such that a fluid passing through the fluid inlet of the container flows into the inlet of the bag filter and outwardly of the outlet of the bag filter so as to flow toward the fluid outlet of the container. A retainer plate is positioned over the platform and has an orifice opening to the inlet of the bag filter.

Abstract: An oil stop valve assembly for allowing a flow of water and blocking a flow of oil has a body having an inlet and an outlet, a seat formed adjacent to the outlet of the body, and a float positioned in the body. The float has a specific gravity of between 0.90 and 0.95 so as to be buoyant in water and to sink in oil. The float is away from the seat when a level of water within the body is above the seat. The float is seated in the seat when the level of water in the body is adjacent to the seat. The body is positioned in a container having a fluid inlet and a fluid outlet. The fluid outlet of the container is connected to the outlet of the body.

Abstract: An antenna cover has a plate with a top surface and outer perimetric edge, and a housing affixed to or integrally formed with the plate. The housing extends downwardly from an underside of the plate. The housing is positioned within the outer perimetric edge. The housing is adapted to receive an antenna therein. The plate is formed of a radio-frequency transmissive material. The top surface of the plate taper slightly upwardly from the outer perimetric edge. The housing has a generally rectangular configuration with an open bottom. The plate is formed of a material such as an acetyl copolymer, and acetyl homopolymer and, or a polyester-reinforced thermoplastic.
