  • Publication number: 20220407312
    Abstract: There is provided a system for assigning power to a plurality of smart appliances. The system includes a plurality of smart outlet assemblies. Each of the smart outlet assemblies is paired to and in electrical communication with a respective one of the smart appliances. The system includes at least one smart breaker assembly in electrical communication with the smart outlet assemblies. The system includes a master server in communication with the smart breaker assembly. The system includes distributed databases used to exchange data among the smart outlet assemblies, the smart breaker assembly, and the master server.

  • Patent number: 7722829
    Abstract: The invention provides a catalyzed soot filter formed on a wall flow substrate having internal walls coated with catalyst compositions. The soot filter maintains a homogeneous flow of the exhaust gases through the internal walls of the substrate along the length of the filter due to the coating design. Both the efficiency and the durability of the catalytic function are increased over conventionally designed catalyzed soot filters. The catalyzed soot filter provides an integrated function for simultaneously treating the gaseous components of the exhaust (e.g., CO and HC) and the particulate matter deposited in the filter.

  • Patent number: 7078004
    Abstract: The present invention relates to a method and article for treating a diesel engine exhaust stream. The stream is contacted with an upstream catalytic composition having a cerium component and/or a zeolite component to reduce the quantity and amount of the particulate matter in the exhaust stream. The stream passes from the upstream catalytic composition to a particulate filter located downstream from the upstream catalytic composition.

  • Publication number: 20050247205
    Abstract: Machine for brewing coffee or beverage having at lease one single-serving brewing module, and at least one multi-serving brewing module connected to a commonly shared pump, water reservoir, and boiler. A flow controller is connected to the boiler, pump, and water reservoir, and in one position, the flow controller is connected to the single-serving brewing module, and in another position, the flow controller is connected to the multi-serving brewing module. The water reservoir, pump, boiler and flow controller are connected in series with suitable piping. The flow rate, temperature, and the amount of water to distribute to brewing module(s) are controlled, monitored and adjusted by a control system. The single-brewing module can be adapted to brew prepackaged coffee pods.

  • Patent number: 5128306
    Abstract: A catalyst composition includes a catalytic material containing a platinum catalytic component dispersed on a bulk ceria and a palladium catalytic component; the palladium catalytic component may be dispersed either on the ceria or on another support, such as an activated alumina support. The catalytic material, which may include a refractory binder, such as alumina, may be dispersed as a washcoat on a suitable carrier, e.g., a cordierite honeycomb-type carrier having a plurality of fine gas flow passages extending therethrough. The bulk ceria may be stabilized with a zirconia stabilizer and/or a lanthana stabilizer. The catalyst composition has utility as an oxidation catalyst and as a three-way conversion catalyst.
