Abstract: The present invention is directed towards a necktie assembly having a separate simulated knot assembly and necktie blade. The simulated knot assembly includes a frustum that has a necktie passageway therethrough. The necktie blade has a front apron with a proximal section and a distal section. A neckband extends from the proximal section of the front apron. In use, the necktie blade passes through the necktie passageway in the frustum, and attaches to a portion of the simulated knot assembly. Because the simulated knot assembly and necktie blade are separate pieces, stylish combinations of simulated knot assemblies and necktie blades can be worn.

Abstract: The present invention is directed towards a method for racking or unracking pipe to or from a rack and a device to facilitate the process. The method provides a controllable procedure for inserting or withdrawing the pipe that is less dangerous than prior art methods and does not damage the pipe end. The method entails inserting a pipe gripper having an expansion sleeve into an accessible end of a pipe. The expansion sleeve is forced against an inner wall of the pipe, coupling the pipe gripper to the pipe. Depending upon the application, the pipe is then either pushed fully onto the rack or is pulled partially off the rack. For unracking operations, a crane sling is attached to the partially unracked pipe and the pipe is further manipulated off the rack.

Abstract: The present invention uses straps and fasteners to adjustably support a receptacle on a patient who is recovering from a surgery or wound. Drainage from the wound or surgical incision is directed into the receptacle, which is fastened to a primary strap in any position that is convenient and comfortable for the patient. The extensive adjustability of the system facilitates prompt patient ambulation by allowing the patient to locate the receptacle in a position that maximizes comfort and minimizes personal inconvenience.

Abstract: A novel set of serrated-planform lifting surfaces produce unexpectedly high lift coefficients at moderate to high angles-of-attack. Each serration, or tooth, is designed to shed a vortex. The interaction of the vortices greatly enhances the lifting capability over an extremely large operating range. Variations of the invention use serrated-planform lifting surfaces in planes different than that of a primary lifting surface. In an alternate embodiment, the individual teeth are controllably retractable and deployable to provide for active control of the vortex system and hence lift coefficient. Differential lift on multiple serrated-planform lifting surfaces provides an means for vehicle control. The important aerodynamic advantages of the serrated-planform lifting surfaces are not limited to aircraft applications but can be used to establish desirable performance characteristics for missiles, land vehicles, and/or watercraft.
