Abstract: A tiny articulation eye and mouth (facial-expression structures) opening and closing structure installable in the hollow interior of a doll head, and utilizing a single, upright-axis motor, and a rotary, co-axial, stepped-diameter drive drum which is rotated by the motor. Circumferential drive tracks formed on the outside of the drum drive followers and actuation which directly impart opening and closing motions in the doll head's eyes and mouth.

Abstract: A children's water toy that has a base unit for directing flow of a fluid in a substantially vertical direction and a spraying unit configured to receive fluid from the base member and rebound the fluid to direct it out of the bottom of the spraying unit so that the spraying unit is maintained aloft by the fluid pressure.

Abstract: Methods for treating bodily tissues and fluid vessels are disclosed. According to a method of repairing a perforation in a bodily fluid vessel, a viscous, moldable substance is inserted into the vessel at the location of the perforation. A path is opened through the moldable substance to permit fluid flow through the vessel. According to a method of introducing a tissue-killing substance into a bodily fluid vessel, a catheter is provided that has a blocking mechanism configured to selectively block and unblock the vessel. The catheter also has a delivery system that is configured to introduce the tissue-killing substance into the vessel. The vessel is substantially blocked upstream of a selected tissue using the blocking mechanism. The tissue-killing substance is introduced into the vessel through the delivery system, and the vessel is unblocked when the tissue-killing substance has substantially traveled toward the selected tissue.

Abstract: A catheter apparatus is provided including an arterial catheter and a venous catheter wherein the distal ends of the catheter are insertable in an artery and a adjacent vein, respectively to a position adjacent a site for creating a fistula. The venous catheter includes a radially expandable structure adjacent the distal end which can be selectively extended outwardly to expand a portion of the wall of the vein adjacent the venous fistula site towards contact with the wall of the artery adjacent the arterial fistula site. The radially expandable structure of the venous catheter may include one or more balloons which can be inflated or a wire basket, or the vein can be expanded by injecting a fluid through an injection port into an isolated portion of the vein.

Abstract: A self-priming centrifugal pump including a supplementary vacuum pump and a float valve. The vacuum pump serves to draw liquid to the pump for priming and the float valve shut of flow to the vacuum pump when liquid reaches a predetermined level to prevent entry of liquid into the vacuum pump. In some embodiments the float valve includes an o-ring valve seal and the vacuum pump includes an oil delivery system to distribute oil from an oil reservoir to improve lubrication.

Abstract: A tank for an excavator vehicle having a frame and body with a hydraulically operated bucket and an engine, the tank comprising a main body mountable to the frame adjacent the engine. The main body has a sealed interior volume with at least one ballast region formed within the interior volume to hold fluid for ballast and at least one discharge region formed within the interior volume to hold fluid for discharge from the tank. There is also at least one valve communicating the ballast region with the discharge region to permit one way flow from the ballast region to the discharge region. A pump having an inlet communicates the discharge region with an outlet. A conduit extends from the pump outlet for delivering fluid forwardly of the excavator bucket. The tank provides ballast for stabilizing the excavator and fluid for fire fighting purposes making the tank useful in fire fighting situations where simultaneous delivery of pressurized fluid and penetration and removal of burning debris is desirable.
