Abstract: There is provided a method and apparatus for segregating ponded coal combustion materials for use in various products, such as block sand products, concrete or mid-size sand products and fine ash products. After screening ponded coal combustion raw materials to remove the first size material for use as a block sand product, the remaining material passes through a rotating magnetic separator to remove iron bearing materials and then to a hydraulic classifier for separating coarse materials, middling size materials and fine materials. The coarse materials are combined with the first size materials and are de-watered to form the block sand product. The middling size materials are segregated into low, middle and high specific gravity materials by the use of spirals. The low specific gravity material is passed through a sizing sleeve and coarse low specific gravity material is combined with the middle specific gravity material and are de-watered to form a concrete or mid-size sand product.

Abstract: A pedal driven propulsion device in the form of an outboard motor for a watercraft, such as a canoe is disclosed. The pedal driven propulsion device having a drive assembly and a propeller assembly with an upper portion and a lower portion. A steering assembly, for steering the watercraft, is coupled to the drive assembly at the upper portion and to a propeller rotatively disposed at the lower portion for providing propulsion to the watercraft when the drive assembly is activated by a human. A mounting assembly for mounting between the gunwales of the watercraft is provided. The lower portion and the upper portion of the propeller assembly have a bevel gear system with a bearing arrangement. The lower and upper portions are cooperatively and driveably engaged with each other by a propeller drive rod. A tilting mechanism is provided to allow the propeller assembly to be tilted.

Abstract: A bookbinding machine includes an advancing track of chain, a plurality of book clamps driveable by said chain successively to one or more processing stations, and means for arresting the movement of a selected one or a plurality of the clamps at one or more of said stations, such as a cover applying and nipping station, while the other clamps remain in motion driven by the chain. The arresting means comprises sprockets for causing a stud on the drive chain to be disengaged from a bracket bolted to the book clamp, to perform an excursion, and to reengage the bracket.

Abstract: For a given temperature differential between a refrigerated heat sink (28) and frontal cryopanel array (46), the mass of the entire cryopump array is minimized by providing thermal struts (54) between the heat sink and the frontal array. The thermal struts extend through, but are isolated from, the primary pumping surface to minimize their lengths. The struts support the frontal array independent of the side radiation shield to facilitate fabrication. To further reduce the temperature differential to the frontal array, heat pipes may be provided. Parallel heat pipes or solid thermal struts may provide the thermal path during cooldown of the system. By reducing the temperature differential between the frontal cryopanel array (46) and refrigerated heat sink (28) through the use of solid thermal struts or heat pipes the load carrying capability of a cryopump can be improved.
