  • Patent number: 9672947
    Abstract: The present invention relates to filters used to remove debris from water being sucked into a piping system. It has particular application use in nuclear power plants, which, after a loss of coolant accident, must pump cooling water back into the reactor core from a collection sump. This water may contain various types of debris that must be removed before the water is sent back into the reactor cooling system. There are restrictions on the allowable pressure drop across the strainer and the space available for installing this equipment. The finned strainer of the present invention addresses these issues while maximizing the quantity of debris filtered from the water.

  • Patent number: 9466849
    Abstract: Provided is a cooling structure for vehicle electrical components that is capable of solving problems due to water contained in intake air. Air used in an electricity generation reaction and air necessary for self-cooling is supplied to a fuel cell stack (11) via an intake duct (2). Dust and chemical substances in the air are removed by a dust/chemical substance filter (3) provided on the fuel cell stack (11) side within the intake duct (2). Furthermore, air and water are primarily separated by a water filter (4) provided in the intake duct (2) upstream by a prescribed distance in the air flow direction from the dust/chemical substance filter (3). Therefore, water in the intake air does not reach the dust/chemical substance filter (3) and the fuel cell stack (11), and various problems due to water contained in the intake air can be solved.

  • Patent number: 7964008
    Abstract: A residual gas cleaner, comprising a manifold assembly having at least first and second inlets and at least an outlet. The first inlet receives spent exhaust gas from an engine, and the second inlet receives clean gas from a fuel tank assembly. A housing assembly comprises a housing that is secured onto the manifold assembly. The housing collects the spent exhaust gas. The housing assembly further comprises draining means to drain the spent exhaust gas from the housing. A filter assembly comprises a filter extending from the manifold assembly and is housed within the housing. The filter assembly filters the spent exhaust gas to create filtered exhaust gas. The filtered exhaust gas exits the manifold assembly through the outlet to join the clean gas. The engine receives the filtered exhaust gas and the clean gas from the outlet.

  • Patent number: 7909921
    Abstract: A pollution control device that provides an external air filtration system for pollutants and other undesirable materials. The system includes a pipe which is attached to the external wall of a building and which provides water to each of the filtration units. An air flow chute is associated with the pollution control device and allows incoming air to pass through a replaceable filter and adjacent to an ultraviolet light setup that are located within each air filtration unit. The air being drawn into the system and subsequently filtered is drawn in by a rooftop device that draws air upward through the device and expels it through the top of the air flow chute.
