Abstract:
Apparatus for generating a ring vortex which will damage the hull of the get vessel. The apparatus comprises a torpedo which is launched from an attack submarine in the direction of the target vessel. When the torpedo is at a predetermined position, the torpedo is detonated. Detonation of the torpedo results in the generation of a ring vortex. The ring vortex is directed toward the hull of the target vessel and will impact the hull of the target vessel with sufficient force to destroy or disable the target vessel. Positioned about the periphery of the torpedo are a plurality of necklace charges. The torpedo also has a central charge which is located near the front end of the torpedo. When detonated each necklace charge forms a ring of imploding gas bubbles which collapse inward. At a predetermined time period after the necklace charges are denoted, the main charge within the torpedo is denoted resulting in the generation of an expanding gas bubble which expands outwardly. The detonation of the necklace charges followed by the detonation of the main charge results in a region of counterflow which causes a substantially circular circulation pattern for the ring vortex.
Abstract:
A self-propelled remotely controlled pilot vehicle adapted for use on raiad tracks to monitor hazardous conditions and obstacles on the railroad tracks. The pilot vehicle precedes a train along the railroad tracks at a distance which will allow the train to come to a complete stop in the event the pilot vehicle encounters a hazardous condition on the track. The pilot vehicle is equipped with a sensor array which measures a variety of different parameters such as the presence of noxious gases, moisture in the atmosphere or at ground level, breakage in one or both rails of the track and orientation with respect to the force of gravity as well as the yaw, pitch and roll of the tracks upon which the pilot vehicle is riding. The pilot vehicle is also equipped with a television camera which provides a visual image of the railroad track ahead of the pilot vehicle to the engineer of the train. An infrared camera which is mounted on the front of the pilot vehicle generates an infrared image of the tracks. Information gathered by the pilot vehicle's sensor array is supplied to a computer on board the pilot vehicle and is also transmitted to the train to enable the engineer to be apprised of conditions existing on the tracks ahead of the train in order to have time to react to dangerous situations on the railroad tracks.
Abstract:
A directional hearing aid comprising a slave microphone for the right ear d a master microphone for the left ear, each of which receive audio information from an external source. The output signal from the master and slave microphones are each provided to fifty hertz bandwidth filters each of which has a center frequency selected from the middle range frequency of the human voice. The output signal from the slave microphone is provided to a modulator which then provides a sixty kilo-hertz frequency modulated carrier signal. The carrier signal is transmitted through the head of the user to a receiver, demodulated and then supplied to a phase comparator. The phase comparator compares the phase of the signals from the master and slave microphones and then provides phase comparison data to a computer. The computer processes the data generating command signals which are supplied to a pair of broad band audio amplifiers. One of the audio amplifiers amplifies the output signal from the slave microphone, while the other audio amplifier amplifies the output signal from the master microphone. The user of the directional hearing aid turns his head toward the direction of the sound until the intensity of the amplified signal provided to each ear is identical, which indicates to the user that his head is aligned with the direction of the incoming sound.
Abstract:
An aerosol dispensing apparatus comprises a housing which includes a top l having a sharp edged orifice and a speaker assembly mounted on a bottom portion of the housing. A sawtooth waveform generator generates and then provides a sawtooth waveform signal which includes a jitter component to the speaker assembly which drives a flexible diaphragm resulting in a reciprocating motion of the flexible diaphragm. The ramp portion of sawtooth waveform signal retracts the flexible diaphragm in a rearward direction, while the approximately vertical portion of the signal causes an abrupt forward movement of the flexible diaphragm. The inner portion of the housing forms a chamber which contains a medication. The jitter component of the sawtooth waveform signal fluidizes the medication suspending the medication in air within the chamber to form a vaporized medication. Each cycle of the sawtooth waveform signal generates one ring vortex of a train of ring vortices with the ring vortex being generated during the vertical portion of the signal when the abrupt forward movement of the flexible diaphragm occurs.
Abstract:
A system for removing airborne contaminants from the effluent air streams om spray paint booths and the like. The system includes a rectangular shaped underground pool having pool of water positioned below the work area. The underground pool has a plurality of suction pipes which are uniformly distributed throughout the pool at a distance of between one and two inches above the pool of water. The suction pipes terminate in a plenum located adjacent the underground pool. A gas turbine engine which is connected to the plenum is used to draw air including airborne contaminants into the plenum from the work area. Solid airborne contaminants such as droplets of water soluble paint, sand and the like will fall into the pool of water. Lighter airborne contaminants, such as gaseous toxins are drawn through the gas turbine type engine into a after-burning incinerator. At the front end of the after-burning incinerator are a plurality of gas burning elements which supply heat to bed of pebbles which may be quartz, zirconium or high temperature ceramics pebbles. The bed of pebbles incinerates the airborne contaminants within the air streams entering the after-burning incinerator expelling clean air into vertical exhaust stack coupled to the exhaust end of the after-burning incinerator.
Abstract:
A dispensing apparatus comprising a reservoir for providing a medication er pressure and a housing which has a centrally located chamber and a wave shaping chamber located in a front portion of the housing. Positioned between the wave shaping chamber and the centrally located chamber is a blast valve. The plunger of a reciprocating piston has a vertical extending support member attached its front end. A power supply provides a square wave signal at a predetermined frequency to a coil alternatively energize and de-energize the coil. When the coil is energized the piston moves rearward. De-energizing the coil results in forward movement of the piston. A plurality of inlet ports positioned around the housing between an inlet manifold coupled to the reservoir and the centrally located chamber allow the medication to enter the chamber as a medicated vapor when the piston is drawn rearward. An impact head attached to the piston unseats the blast valve when the piston moves forward allowing medicated vapor to enter the wave shaping chamber. An edged shaped orifice at the front end of the housing communicates with the wave shaping chamber allowing medicated vapor to exit the wave shaping chamber and pass through the edged shaped orifice to form a ring vortex of medicated vapor. The blast valve opens and closes at the predetermined frequency causing the aerosol dispensing apparatus to generate a train of the ring vortices of medicated vapor.

Abstract:
A gas projection apparatus for disabling the engine of an automobile beingursued by, for example, a police cruiser. The gas projection apparatus comprises a housing having a charging chamber which receives carbon dioxide gas under pressure from an external source of supply. The charging chamber is partially sealed by a blast valve which is attached to a movable shaft centrally located within the housing. There is also attached to the movable shaft a diaphragm which is positioned in a rear chamber of the housing adjacent the charging chamber. Carbon dioxides from the charging chamber is supplied to the rear chamber exerting a force on the diaphragm. When the force exerted by carbon dioxide gas on the diaphragm exceeds a predetermined pressure level, the diaphragm moves the shaft unseating the blast valve which the pressurized carbon dioxide gas to enter a wave shaping chamber within the housing. A pair of annular ports at the front end of the housing receive the pressurized carbon dioxide gas from the wave shaping chamber and, in combination, with the wave shaping chamber form a train of ring vortices of carbon dioxide gas. The train of ring vortices of carbon dioxide gas is directed to the engine of the automobile being pursued causing the automobile to slow and eventually stall.

Abstract:
A video system, comprising a pair of digital video cameras and a data prosing system, which is used to determine the location of a golf ball during flight and the location of the golf ball when its flight is completed. The video cameras are fixedly mounted on a golf cart and boresighted to insure that the field of view for one camera overlaps the field of view for the other camera allowing the golf ball to be tracked after the golf ball is struck by the golfer. Each of the video cameras has an image array comprising a plurality of image sensing elements. As the golf ball travels along its flight path a light image of the golf ball is detected by at least one of the image sensing elements of the image array for each camera during a scan of the camera's image array. Each camera generates a data bit stream indicating the location of the image sensing elements on the image array which sense the golf ball's light image for each scan of the image array. The data bit streams are supplied to the data processing system which then calculates the departure vector, a trajectory path and a circular impact probability (CIP) location for the golf ball when the golf ball lands on the golf course. A monitor provides the golfer with video data indicating the golf ball's circular impact probability location.
