Abstract: A trimaran having a hull and outrigger pontoons on each side of the hull. The pontoon are laterally movable away and towards the hull. Each of the pontoons are secured to the hull by forward and aft link boxes. The link boxes are pivotally mounted to the port side and starboard side of the hull. Each of the link boxes are also pivotally secured to a pontoon. The forward and aft link boxes of each side are connected together by a linkage whereby the forward port side and starboard link boxes are arcuately rotated when the aft port side and starboard link boxes are arcuately rotated.

Abstract: Method and tool for fracturing the cement interface between a crown and a tooth or the like. The method is accomplished by positioning a piezoelectric driven rapid impacting tool against one side of a portion of a crown covering the tooth. The tool is covered with a malleable metal and is interfacing abutment with said crown. The opposite side of the crown is abutted against an anvil which is covered with a thicker malleable metal interface.

Abstract: A control surface for an air vehicle (e.g., an aircraft, rocket, or missile) is useful for flight control at both subsonic and supersonic speeds. The control surface defines the outboardmost tip of a flight structure (e.g., a wing, tail or other stabilizer) of the air vehicle. Hence, the control surface is referred to as a ‘tiperon’. The tiperon has an approximately L-shaped configuration, and can be rotated relative to a fixed portion of the flight structure about a control axis. The respective surface areas of the tiperon sections forward and aft of the control axis are proportioned to place the subsonic center of pressure aft of the control axis to enhance aircraft control, and preferably also forward of the centroid of tiperon surface area. Also, the control surface sections forward and aft of the control axis are preferably mass-balanced, or at least nearly so, to enhance aircraft control at supersonic speeds.

Abstract: A liquid applicator includes an elongated hollowing body having opposed first and second open ends in fluid communication with one another, and a tip attached to the first open end and including a porous material. A closed, frangible ampule is supported within the second open end of the body and contains a liquid to be disposed.

Abstract: A vehicle imaging surveillance and recording system adapted to monitor conditions prevailing during the course of a trip and provided for this purpose cameras are placed in the control station of the vehicle and about the vehicle. At least two recording devices record the output of the cameras. One device records a thirty minute high resolution image. The second device records a two hour lower resolution image. Both devices compress the data that is to be recorded in storage. The output signals yielded from storage are fed into an on-board transmitter to modulate a carrier that is radiated from the vehicle and intercepted by an active communications satellite. These output signals are being transmitted only under certain conditions. One condition is to provide a switch under the control of a crew member in the control station of the vehicle. The other condition provides for automatically switching on the transmission to the satellite when certain parameters occur.

Abstract: The present invention pertains to two inserts to be used in conjunction with the nozzles of known liquid flow through applicators. The inserts have a proximate flange detailed to fit into a wider portion of the applicator and a bristle or dabber portion at its distal end detailed to extend beyond the applicator. The bristle or dabber portions are connected by an elongated rod portion. In one embodiment the rod portion is crisscrossed with a clockwise thread and a counter-clockwise thread whereby two disparate liquids may be mixed together through the flow transitory passage of the liquids in the nozzle. In the second embodiment the rod portion is essentially smooth. However, the external diameter of the rod is substantially less than the internal diameter of the passage of the applicator whereby an annular space is formed.

Abstract: A marine anchor having integral flukes which have together a delta configuration. The flukes have a trailing arcuate edge. Each fluke has a wedge cut into the trailing portion to provide extending outer fins. The fins are turned downwardly to provide flaps that produce a self righting anchor and one that results in a horizontal planing when the anchor is pulled.

Abstract: The invented apparatus includes at least one acoustic sensor, a mapping unit, a controller, and a transducer. The sensor is coupled to an object to be inspected for damage, and generates a sensed signal based on acoustic signal occurring in the object under an applied load, which signal may or may not be the sound of damage occurring in the object. The mapping unit is coupled to receive the sensed signal from the sensor, and generates damage data based thereon. The controller is coupled to receive the damage data from the mapping unit. Initially, the apparatus is in a passive mode in which the apparatus senses an acoustic signal from the object. If the damage data indicates that the object has incurred possible damage in the passive mode, the controller switches to active mode and outputs induced signal data. The transducer is coupled to the object as well as the controller, and induces acoustic signal in the object, based on the induced signal data.

Abstract: A method for applying flock to the end of a tube which is to be used as a flow through applicator. An external end portion of the tube is coated with an adhesive, air is intermittently blown through the tube to keep the tube clear of unwanted adhesive. The end of the tube coated will the said uncured adhesive in then subjected to an application of flock under the aegis of electrostatic attraction while air is intermittently blow through the tube to thereby keep the tube essentially clear of flock. The tube carrying the flock is subjected to a heat cure. The tube may be of metal or a plastic. When the latter the end portion of the tube is subjected to a preliminary corona discharge whereby to active its service to increase the adhesive to the adhesive coating in a known manner.

Abstract: An applicator that has an elongated tubular handle with a proximate and a distal end. The distal end has a dauber of a foamed material which is coextensive with said handle and has a diameter the same as said tubular handle, the formed material is cylindrical thereby providing a recess which is preloaded with a to-be-dispensed liquid. The handle is provided with an annular ring. A cup with a mouth portion is mounted about the foamed material. The mouth portion is affixed to said outer circumference of said ring. The cup has an annular weakened score line whereby said cup may be broken away to expose said foamed material.

Abstract: A blood vessel wall-defining device for repairing an abdominal aneurysm. The device comprises a percutaneously-insertable structural frame extending between first and second ends having an unexpanded diameter which is smaller than the diameter of the blood vessel to permit the structural frame to be placed into the blood vessel. The structural frame being expansible to form a cylindrical structural skeleton having a slightly larger diameter than the blood vessel to facilitate the securing of the skeleton in position in the blood vessel. The skeleton has a sheath of a tubular fabric. The said structural frame has a plurality of spaced coiled stents prior to expansion which are uncoiled under the aegis of a balloon catheter and locked into position by ratchet means.

Abstract: A fluid applicator which is constructed of a relatively rigid plastic with a forwardly disposed distal end portion or nozzle which is constructed of a plastic material which is relatively more resilient. The applicator in some embodiments being adapted and constructed to be affixed to a syringe containing a to-be-distributed relatively high viscosity liquid or gel.

Abstract: Method and apparatus for impingement on the sonic wave produced by a supersonic gas flow and the gas flow in a boundary layer of a gas that interfaces with a solid substrate comprising providing a source of a mixture of ions and electrons, introducing said ions and electrons into the region behind the sonic wave and ahead of the boundary layer, separating said ions and said electrons in said region maintaining a substantial portion of said ions proximate said region and maintaining a substantial portion of said electrons remote from said region.
