Abstract: An ultrasonic surgical device is disclosed including a surgical tool including a proximal transducer mounting portion defining a surface, a distal end effector end, and a waveguide disposed therebetween, the waveguide extending along a longitudinal axis. The ultrasonic surgical device further includes a transducer is in mechanical communication with the surface of the transducer mounting portion. The transducer is configured to operate in a D31 mode with respect to the longitudinal axis of the waveguide. Upon activation by an electrical signal having a predetermined frequency component, the transducer is configured to induce a standing wave in the surgical tool to cause the end effector to vibrate, the standing wave having a wavelength proportional to the predetermined frequency component of the electrical signal.

Abstract: The present invention provides an interconnect for an attitude control device. The interconnect includes at least one bus adapted to provide at least one bus signal to the attitude control device and a plurality of electrical contacts external to the attitude control device and capable of providing a signal indicative of a physical location of the attitude control device when the attitude control device is installed.

Abstract: The present invention provides an interconnect for a location dependent device. The interconnect includes at least one bus adapted to provide at least one bus signal to the location dependent device and a plurality of electrical contacts external to the location dependent device and capable of providing a signal indicative of a physical location of the location dependent device when the location dependent device is installed.

Abstract: The therapeutic apparatus of the present invention includes a portable case having a hollow interior for housing a motion-generating case or housing wherein the front end of the assembly is provided with an elongated slot for extending an elongated rod therethrough. The rod is provided with a resilient foam collar over which is mounted a penetration member adapted to penetrate a selected body orifice for providing sexual stimulation, gratification and pleasure. The motion-generating assembly within the hollow interior of the portable enclosure includes both a horizontal motion-generating assembly and a suspension assembly for producing a generally variable vertical up and down component to the motion provided by the horizontal drive assembly. An electric motor is used to drive an eccentric disk. A yoke positioned on the disk is adapted to move the elongated rod reciprocally back and forth in a generally horizontal direction.

Abstract: A ball-launching system for a dog's ball which automatically launches or shoots a ball along an airborne path, thereby enabling the dog to chase the ball, fetch it and return it to the system. The system includes a ball collection area for receiving the returned ball, dropped or otherwise deposited therein by the dog, and for feeding the returned ball, under the force of gravity along, into the hollow interior of a ball-launching tube. As the ball rolls down the hollow interior of the tube, a sensing device detects the passage of the ball therover and generates a command signal. The command signal is delayed a predetermined period of time, sufficient to enable the ball to contact the rear end of the tube and come to rest in a firing position.

Abstract: This invention concerns an improved round for use in liquid propellant gu The improved round comprises a projectile attached to a carrier which is shaped like an abbreviated cartridge case. The carrier has a plurality of injection ports that communicate to an expandable volume. Sealing means prevent the escape of liquid propellant from the expandable volume which upon injection causes the projectile to be pumped to a forcing cone leaving the carrier behind. Several ignition means are used employing Boxer, Berdan or electric primers.

Abstract: A round of ammunition uses both a solid propellant and an oxygen-rich, lid monopropellant. The liquid propellant is held within a plastic container within the conventional case.

Abstract: A duplex projectile to be fired from a gun bore is made up of a tubular pectile and a conical shaped projectile fastened within the tubular projectile by means which are capable of withstanding acceleration forces on the round while the round is within the bore after being fired but which release the conical projectile from the tubular projectile once the two exit from the bore.

Abstract: An improved tubular projectile formed from a single piece body member hav a ball valve resiliently held in a closed position therein and a method of manufacture is disclosed.

Abstract: A hybrid gun system provides the benefits of both solid and liquid propelts by utilizing a shortened conventional cased ammunition which utilizes the propellant gas generated by the solid propellant contained within the cartridge case to operate a concentric fluid injection system to result in a compact firearm which offers possibilities of retrofitting conversions for certain applications.

Abstract: A gas-pressurizer is disclosed. An enclosed canister surrounds a piercing chanism, over the end of a pressure-conducting pipe. The piercing mechanism is comprised of an end-cap with portals therethrough, a stub, and a gas dispensing, piercing pintle riding upon the stub. When pressurized gas is sent through the pipe, it forces the pintle through the upper end of the canister, allowing the gas to pressurize a storage tank.

Abstract: A spin-velocity actuated ball valve in a hollow-nose, hollow base projectile is positioned to selectively close or open a projectile. In the closed position normal propellant pressure or projectile carried propellant causes the projectile to achieve operational velocity. In the open position a conduit through the projectile reduces frontal area and tail drag caused by turbulence.

Abstract: A liquid propellant gun and gun loading process wherein a predetermined ant of a gas is intimately mixed with the propellant charge.

Abstract: Measurement and correlation of chamber pressure and projectile position d is accomplished using an array of phototransistors, illuminated by collimated light, which phototransistors are sequentially switched off due to the interruption of the collimated light by the passing projectile. Pulses generated thereby may be displayed on an oscilloscope along with the pressure-time trace.
