    摘要: A method and apparatus for digging and removing excavated material from a selected site provides a mobile device having a chassis that is movable or self-propelled. The mobile device has an elongated, preferably articulated boom with a free end portion having a digging implement that can include a digging tool, excavating tool or jetting tool. The boom preferably comprises at least three sections. The boom sections are foldable to a storage position on the chassis wherein one boom section stacks upon or is aligned with another boom section. The vacuum line is supported upon the boom wherein the vacuum line extends between the free end portion of the boom and the chassis. The boom attaches to the chassis at a base that can include a rotary or pivotal connection. The vacuum line supported by the boom extends along the boom and above the earth's surface. A selected material is excavated with the excavating implement (e.g., jetting tool or digging tool). The excavated material is vacuumed with the vacuum line into a collection vessel or tank that can be a part of a wheeled vehicle thus enabling transport to a disposal site. A separate vacuum truck can provide a vacuum to a selected collection tank.

    摘要: The present invention provides a method of replacing a failed pump seal of a pump having a pump housing and a rotating pump shaft. As part of the method, there is provided a specially configured rescue seal. The rescue seal is placed on the pump shaft above the failed seal so that the pump shaft extends through both the failed seal and the rescue seal. In order to affix the rescue seal to the pump shaft and above the failed seal, a plurality of studs are first attached to the pump housing after removing some of the bolts that fasten the failed seal to the pump housing. The failed seal is then secured to the studs with nuts. Nuts are then placed on the studs to secure the rescue seal to the studs above the failed seal.

    摘要: The present invention provides an aortic embolic filter mounted on a catheter. A pair of spaced apart hubs are provided, one hub being a catheter hub mounted on the catheter, the other hub being a tip hub spaced distally of the catheter hub. A filter basket is attached to the hubs and positioned distally of the catheter hub. The basket includes multiple supports that each span the two hubs. A filter material/sheet is supported by the supports, the filter material having concave and convex surfaces, first and second edge portions, and an opening that spans most of the distance between the hubs and in between the filter material edge portions. One of the supports is movable relative to the catheter hub. An operator, controller or handle enables the movable support to change length between the hubs to put more or less of a curvature of the filter basket.
