摘要: A power distribution system. In one embodiment the system includes at least one rectifier cabinet, at least one distribution cabinet, and a pair of conductors. Each cabinet has a side wall which is adjacent to the side wall of the other cabinet. Further, the rectifier cabinet includes slots for rectifiers and the distribution cabinet has slots for distribution modules. The conductors are coupled to the cabinets. One of the conductors may terminate a first wire connected to a rectifier slot and may terminate a second wire connected to a distribution module slot. The other conductor may complete a DC return path to the rectifier cabinet. In one embodiment AC and DC cables may be routed through the top or the bottom of the cabinets. In another embodiment the conductors are bus bars positioned near the back of the cabinets. Rectifier and distribution cabinets and associated methods are also provided.

摘要: A pressure relief valve has a moveable piston disposed in a body between inlet and outlet ports in the body. A volumetrically variable enclosed chamber is formed within the body with a portion of the chamber being defined by an upper surface of the piston. At least one aperture extends through the head of the piston providing a fluid passageway between an inlet port of the valve and the enclosed chamber. Fluid captured within the enclosed chamber permits initial rapid movement of the piston head to an open, or relieved, position in the event of a sharp increase in system pressure and provides a hydraulic cushion whereby impact shock of the head against internal valve components is attenuated.

摘要: A building material for cement based facing such as stucco and brick facing. A thin layer of water impervious epoxy is applied to one side of a wallboard or plywood sheeting. Sand is imbedded in the epoxy in a manner to fully cover the epoxy. The sand surface provides a compatible bonding surface for stucco and mortar which are then applied in a conventional manner.
