    摘要: An opposed piston engine includes at least one cylinder with a bore surface and longitudinally-spaced exhaust and intake ports that open through the sidewall of the cylinder. A pair of opposed pistons is disposed in the cylinder for sliding movement along the bore surface. An oil-retaining surface texture pattern in an interface between the pistons and the bore surface extends in a longitudinal direction of the cylinder, aligned with bridges of at least one port. The surface texture pattern includes a plurality of separate recesses on an outside surface of a skirt of each piston. Alternatively, or in addition, the surface texture pattern includes a plurality of separate recesses extending in a longitudinal direction of the cylinder, aligned with bridges of at least one port.

    摘要: An online system for permitting users in a data network to manage inventories of their collectibles (including antiques) includes a database of collectibles, user inventory files, user information files, a database of needed items and items available for sale, and a server-based task for managing and searching the database of needed items and items available for sale. The database of collectibles includes object classes indexed by primary classes and subclasses, and user inventory files storing inventories of instances of the object classes, including instances that each user has, instances that each user would like to sell, and instances that each user would like to buy. Users may access their respective inventories by inspecting, editing, and adding the instances to the user inventories; obtaining valuations of instances in their inventories; and insuring instances in their inventories. The server-based task finds buy-sell opportunities between the users when one user has an instance of at least one object class that said one user would like to buy and another user has an instance of said at least one object class that said another user would like to sell.
