Abstract: This is an intravascular prothesis deliverable percutaneously with several cardiac applications including but not limited to heart valves, intravascular narrowings and cardiac defect occlusion. The device has a detachable sac connected through a thread or wire outside the body where it is immobilized. The device can remain inside the heart for as long as it is clinically useful in non permanent applications (valve, throttle); at any point it can be retrieved by pulling it outside the body by the holding wire/thread. In permanent applications (defect occlusion) the wire/thread can be withdrawn allowing the sac to endothelialize.

Abstract: A storage hopper is placed upstream of an inclined cleaner to prevent a surge of cotton from choking down the inclined cleaner. The output of the storage hopper is limited by feed rollers.

Abstract: A foot operated device for crushing beverage cans.

Abstract: A drinking vessel is placed in a horse trailer. To prevent water from sloshing out of the vessel, an opening in the top of the vessel has a tube shaped shield extending into the vessel.

Abstract: Seed cotton is carried by an airstream into an upright cleaning chamber. Dust and fine trash is carried off through a fine screen in the top of the chamber. The airstream carrying the seed cotton into the chamber will lack sufficient strength to carry the cotton to the fine screen through which the dust and fine trash is carried. The air is separated from the dust and fine trash in a cyclone separator. Larger trash is blown through or carried through a grid on the side of the chamber. The cotton falls to the bottom of the chamber and is carried off with a majority of the air. The fine trash and coarse trash are dropped into a conveyor to be removed.

Abstract: Thin metal adaptor rings fit within elastomeric seal rings holding an orifice plate within a fitting. The thin metal rings have an inside diameter equal to the inside diameter of the pipe line and fitting. Therefore, the inside diameter is maintained without variations as previously resulted from protrusion or recess tolerances of the elastomeric seal rings. The seal ring is modified with notches to hold the thin metal adaptor rings in the desired position.

Abstract: A dispenser for storing and dispensing jump ropes includes a container having a longitudinal slot that runs over a substantial length of the container. A handle and the rope of a jump rope are placed in the container, and the other handle of the jump rope is placed in the slot of the container.

Abstract: The stems and limbs of a root crop plant are lifted from the ground, folded over a gathering bar, and grasped by an auger-paddle. The roots below the crop are severed by a cutter bar which resembles a rod weeder. While the crop is held the soil beneath the crop is pulled from the be in which the crop grows into a furrow on either side of the bed. As much as possible the root crop is cleaned as it is lifted up by the rotation of the paddle-auger while the limbs and stems of the plant are caught within the paddle-auger and held by the helicoil. After they are lifted free of the soil they are moved from two beds toward a furrow between those two beds and discharged in a windrow by a roller which rotates the opposite direction of the paddle-augers.

Abstract: Aircraft communications are established on a cellular system by having the transmission to aircraft directed above ground level so as not to interfere with ground cellular systems and having the transmissions from the aircraft at extreme low power levels so as not to interfere with transmissions from ground vehicles. The location of mobile stations either aircraft or ground vehicles for one embodiment is determined by Loran reception or other radio navigation system in the mobile station and transmitted to a mobile switching center to be used in transferring control from cell to cell by use of the determined location of the mobile station. For another embodiment the antennae for aircraft (both base station and mobile) are horizontally oriented while ground vehicle antennae (both base station and mobile) are vertical as in present commercial practice.

Abstract: Prongs driven by a hydraulic motor break up packed seed cotton beneath the mouth of a suction pipe.

Abstract: Seed cotton on a wire mesh belt is dryed and cleaned by a downflow of heated air. The natural separation and falling of trash from the belt is increased by shaking the mass of seed cotton upon the wire mesh belt. The belt is flexed to shake the seed cotton upon it. The belt is flexed by running the belt over "V" shaped intermittent supports. The belt is also shaken by being bumped by gussets on rollers beneath the belt. The air is exhausted from beneath the belt by ducts extending across the chamber. The tops of the ducts are inclined planes so that the trash slides from the top of the duct and does not accumulate on the top.

Abstract: A column of fast moving air with entrained seed cotton is jetted upward from a nozzle in the bottom of a fountain dryer. The column will remain intact until it hits the top of the fountain dryer. At the top, the column will disburse and the mixture of air with entrained cotton will return to the bottom of the dryer in an annulus between the column and the wall of the dryer. There will be an interface of the upward column with the downward annulus. The opposing flows will be roiled and cause turbulence at the interface between the upward column and the downward annulus. The rolling and turbulence will be increased along the walls of the vessel by structure which will reverse the direction of the downward flow of the cotton. The downward flow of the cotton is collected in an annular plenum surrounding the bottom of the column and is directed to an outlet duct. The outlet duct and the annular plenum with the inlet at the center thereof, form a banjo separator.

Abstract: Tongs have two arms pivoted together. A finger extends at an angle from one end of each arm. The tongs are used to remove a filter from a hood above a grill. A frame on the filter in the hood is engaged by the tips of the fingers when the fingers are extended. Then the filter with the frame is pulled from the hood.

Abstract: An expandable and contractible covering is over the polished rod and the polished rod liner from above the polished rod liner clamp to below the stuffing box. This covering protects the environment in the event of failure of the liner or stuffing box. The covering may be quickly released from a basin below the stuffing box and contracted upward to service the stuffing box. The basin is connected to a special fitting between the stuffing box and pumping tee.

Abstract: A barbecue pit has a oven and a firebox mounted upon a frame which includes a reach pole, wheels, and a trailer hitch. The heat and smoke from the firebox enters into the bottom of the back of the oven. A baffle regulates the flow of heat into the oven and prevents flames from entering the oven. A chimney has its intake located at the bottom of the front of the oven and extends to sufficient height to prevent smoke from getting in the eyes of attendants. Access to the oven is by a rack opening. A rack rolls in and out of the oven on rollers and has a series of doors which close the rack opening of the oven when the doors are aligned therewith. The rack opening and intermediate doors, the oven is rarely opened so that smoke and heat escapes therefrom.

Abstract: A well casing cleaning tool includes a tubular tool body that has a central axial passageway and upper and lower sets of jet ports through the tool body wall. The upper jet ports are angled upward and the lower jet ports are angled downward. The outside diameter of the cleaning tool is slightly smaller than the inside diameter of the well casing to be cleaned. When wash fluid is pumped through the jet ports of the cleaning tool, an area of reduced pressure forms between the upper and lower sets of jet ports. This area of reduced pressure aids in the cleaning of the perforation zone of a well. Bypass passages from above the upper set of jet ports to below the lower set of jet ports prevent a pressure difference between the two sets of jet ports.

Abstract: A laser sighting unit is attached to a putter or a wedge. The laser sighting unit includes a clamp which attaches an adjustable bracket and a laser unit to the shaft of a golf club. The laser unit is activated by a switch that is removably attached to the handle of the golf club. The laser sighting unit can be attached or removed from a golf club without any alterations to the golf club, and without the aid of tools. The laser sighting unit is used to aid a golfer in obtaining proper alignment of the golf club before the golf ball is hit.

Abstract: The wheel tracks of a center pivot irrigation system are changed by expanding or contracting a telescoping joint located between the center pivot and the first vehicle from the center pivot. The power to expand or contract the telescoping joint is obtained from the first vehicle so that all of the vehicles are in motion at the time the change is made. The telescoping joint has a removable sleeve so that sand may be washed from the telescoping joint.

Abstract: This is an intravascular prosthesis deliverable transvenously for the occlusion of large heart defects. The defects are predominantly large atrial septal defects and ventricular septal defects. The device has an occluder connected with a centering counter-occluder. The device is delivered to the heart by known methods. The occluder is released on the distal side of the defect and the proximal centering counter-occluder is stretched, pulling the device over the center of the defect. Subsequently, the centering counter-occluder is buttoned against the occluder and is opposing the right atrial side of the septum. The radiopaque button is placed upon a string to verify buttoning.
