    摘要: An ion thruster comprises a chamber in which propellant is ionized and an accelerator grid, whereby a flow of ions out of the chamber provides reactive thrust. Charge exchange between neutral atoms of propellant and fast moving ions produces slow ions which impact on the accelerator grid and erode it by sputtering, thus limiting the lifetime of the thruster. The invention includes an accelerator grid comprising a layer which includes graphite providing resistance to erosion and a support layer which overcomes the restrictions on engineering and strength of graphite. The accelerator grid can be constructed by machining a block of graphite 12 to produce an upper surface 13, to which the molybdenum grid 14 can be fixed. The block 12 can then be cut away to permit the graphite to be machined to the same contour as the surface 13. Apertures are drilled through the graphite using the existing apertures of the grid 14 as guides.

    摘要: This invention involves a system and method for the installation of a prefabricated composite structural members. The system utilizes deck panels which have a plurality of steel C-beam pairs attached to the underside such that a series of channels is formed. Bored through each deck panel is a plurality of access holes which projects through the panel and into one of said channels. Thus, installers can access underlying bridge girders from the surface of the deck panels thereby allowing for top-side installation. The system also provides a top-side vertically adjusting device for raising or lowering the deck panels to allow for the top-side installation of shimming devices.

    摘要: A thruster system has a main bipropellant propulsion unit including a propulsion engine (50) and bipropellant supply having a tank (3) for an oxidizing agent and a tank (4) for a fuel. An auxiliary cold propellant thruster (21) uses propellant supplied by bleeding off vapor from the contents of the oxidizing agent tank (3).

    摘要: The present invention provides a fish cage having a body portion and floats or weights attached thereto at one of a plurality of different positions so that the cage will float in water with a first part exposed and a second part submerged. Changing the position of attachment of the floats or weights results in different first and second parts being respectively exposed and submerged allowing successive cleaning of different first parts of the cage body.

    摘要: The invention is system and method to recognize speech vocalizations using context-specific grammars and vocabularies. The system and method allow increased accuracy of recognized utterances by eliminating all language encodings irrelevant to the current context and allowing identification of appropriate context transitions. The system and method creates a context dependent speech recognition system with multiple supported contexts, each with specific grammar and vocabulary, and each identifying the potential context transition allowed. The system and method also include programmatic integration between the context dependent speech recognition system and other systems to make use of the recognized speech.
