Abstract: Apparatus and method for protecting a producing oil well's sucker rod string from wear as the rod string reciprocates in the well's tubing string. Each rod guide has a network of passages encased within the body of the rod guide. As the sucker rods and rod guides move up and down through the tubing string, produced fluid is channeled through tunnels in the passages to exit ports from which the fluids are discharged at high velocity away from the guide. The fluid exits with suffficient force to push the rod string away from the tubing string at each exit port. In this way the streams of fluid tend to centralize the rod string near the center of the tubing string thereby averting contact between not only the rod string and the tubing string, but also between the guide itself and the tubing string. The discharged fluid also provides lubrication between the guide and tubing string in the event that contact between the components does occur.

Abstract: A reciprocating pump for pumping water uses a displacement plunger which operates with a seal in the middle of a cylinder within which it reciprocates. A portion of the water flows from above the plunger and a portion of the water flows from below the plunger through an annulus between the cylinder and a housing. The valves are all rings concentric with the axis of the plunger, cylinder, and housing.

Abstract: This invention is a mowing machine which is to be hitched to the back of an agricultural tractor. The primary purpose of the invention is to cut and clean vegetation and debris from along agricultural fence rows. The cutting assembly of the mowing machine includes flails which are rapidly rotated and are made from fabric reinforced rubber. The flails are flexible and are about two feet long, about three-fourths of an inch thick, about three inches wide, and weigh about five pounds. The invention may be used to cut and remove vegetation and debris from under fence rows since the flails are flexible and easily mow around fence posts without damaging either the posts or the flails. The cutting assembly can be positioned so that a plane in which the cutting flails rotate is either inclined or declined to match the inclined slopes of embankments and declined slopes of drainage ditches.

Abstract: A tray attaches to both arms of a folding lawn chair. In the unfolded position the tray is horizontal and the back portion of the tray is toward the back panels of the chair. In the folded position the tray is vertical and the back portion of the tray is toward the front of the arm. In the folded position the tray latches the chair in the folded position and the tray must be removed to unfold the chair. The tray has button knobs on the bottom surface of the back portion which attach into keyhole slots in the top of the arms.

Abstract: An attachment that connects a decorative logo to footwear. The logo is displayed along the lower leg outside the pant leg. The logo can be attached to either a shoe or a boot. The attachment takes the form of a U-shaped holder when being attached to a boot and the form of a L-shaped holder when being attached to a shoe. The attachment includes a vertical strip of plastic which projects upward from the footwear towards the knee on the outside of the pant leg. It is on top of this vertical strip that the decorative logo is placed. The logo can be displayed at various heights by varying the length of the vertical strip and the attachment is painted so that it blends into the background of the pant leg. Another benefit provided by the attachment is that it restrains the pant leg at a height above ground level preventing the soiling of the pant leg.

Abstract: Hydraulic fluid is replenished in a pulsator chamber of a fluid driven pulsator pump by having the power plunger in an upstanding bore with spaced seals. The power plunger is withdrawn upon each stroke vertically upward. As it is withdrawn past seals, any gas within the pulsator chamber may be purged or bled into an annular space and there out into a reservoir and scrubbing chamber. Additional hydraulic fluid will flow into the pulsator chamber. Upon the down stroke of the plunger an exact amount of volume will be displaced within the pulsator chamber. Adjustment of the product pumped on each stroke is by sacrificing a measured amount of the pulsator liquid into a sacrifice chamber. The amount of liquid which flows into the sacrifice chamber upon each down stroke and out of the chamber on each upstroke is adjusted by adjusting the movement of a floating piston by a micrometer rod.

Abstract: A retractable bumper is mounted to the rear of a cotton module transport. The bumper is attached to elongated shafts which are pivoted in tubes. The tubes are mounted upon a bracket which is hinged below the bed of the transport. Before the bed is tilted to a lower position, the bumper is telescoped forward in the tubes and the tubes tilted so that the bumper is moved against the bottom of the bed.

Abstract: The lint from the roller gin stand is divided into two streams and a small portion is recirculated through the feeding equipment so that the lint to seed ratio is increased at the roller gin. The pre-gin equipment acts to distribute and break up not only wads of cotton but also individual locks of cotton into smaller components called individual seed locks. Some seed will be completely separated from lint in this process. This process of preparation of the seed cotton for the ginning will actually partially pre-gin the cotton. It is accomplished by wiping the cotton by spiked rollers over concave segments some of which have projecting bars from them. The cotton is pulled or diverted over separation ridges which project between the rollers.

Abstract: A tractor includes front wheels and rear wheels. A three-point hitch connects a yoke to the tractor. The yoke is stabilized by stabilizer arms which are connected under the rear tractor axles and to the frame of the tractor forward of the rear tractor axles. The stabilizer arms lock up the yoke so that it is rigidly fixed to the tractor when an earth working implement tilling the soil is stressing the yoke. The stabilizer arms are connected to the yoke by chain links which permit the yoke to be raised and lowered by the three-point hitch, but which prevent any lateral movement or flexibility to the yoke. This rigidity in part is by having the chain link connection of each stabilizing link straddle the connection of the three-point hitch to the yoke. In addition, the two stabilizing arms are connected by a cross brace which is bolted in place. The cross brace may be unbolted in the event a power takeoff shaft is to be used, which would otherwise be blocked by the cross brace.

Abstract: Weights in the form of water-filled flexible tubes are attached onto the pressure supported roof membrane of a building. The weights contour the membrane from a single dome into smaller elongated domes. The decreased radii of curvature of the smaller domes substantially reduce both the stress within the membrane and tension exerted by the membrane on the building walls.

Abstract: Gears with a soft metal hub and a hexagonal coaxial hole in the hub, often need repair. Accordingly the old hub is removed and a new solid plug is pressed in place and welded. A radial face on the plug and the gear are flush. A lock plate is placed on this radial face and wleded along an arc. Then the assembly has an axial circular hole bored therethrough and then a hexagonal hole is broached therein. The lock plate has two ears opposite the weld which receive a bolt.

Abstract: A method and apparatus for accelerating the removal of fully ginned seed from a seed roll established in the roll box of an operating gin stand, whereby the capacity of the stand is enhanced. The apparatus is characterized by a set of vanes attached to a finger shaft, said finger shaft being rotatable to change the angle of projection of the vanes to control the residual lint on the seed. The vanes are located so as to project into a vertical seed discharge shaft as the seed roll sags in its rotation toward the saws. The vanes are spaced to permit the seed roll to rupture as it passes over the vanes and the roll sags into the gap between the vanes, thus releasing fully ginned seed into the seed discharge shaft outside the surface of the saw between the vanes.

Abstract: An exercise device includes a shoe having a wooden sole resting upon a wooden base plate. A backsaw handle is attached to the shoe. Therefore, stroking the handle causes the shoe to reciprocate upon the base plate providing a satisfying sound of the wooden shoe rubbing on the wooden base plate. A heel notch on the top of the shoe provides means for stroking the shoe with the foot. The weight of the shoe may be increased by placing weight straps in a tray upon the shoe. In a second embodiment the shoe includes a backsaw and miter box. The base plate forms the bottom of a box which encloses the shoe.

Abstract: An adjustment for a MacPherson strut of an automobile is provided by modifying the top bearing retainer to provide an inward circular lip. Two plates are clamped to this lip. Before clamping, the plates are rotatable relative to the bearing retainer so that the center of an eccentric hole therein moves along a circle which is concentric to the bearing retainer and thus the bearing. The upper end of the piston rod of the strut is mounted in the eccentric hole so that the position of the upper end of the strut can be moved relative to the body and also within the bearing and helical spring.

Abstract: A clear plastic sheet has drawn thereon, the excision necessary to remove a skin defect and also drawn thereon, lines indicating the incisions necessary to make a flap. The transparent sheet is placed over the defect to orient the flap location. Perforations along the lines in the clear plastic sheet permit the skin to be marked so that the drawing on the sheet may be reproduced upon the skin.

Abstract: A base in the form of a tube is attached to the dash of automobile. The bottom of an accordion pleated shade is attached to the base. A strip of pliant fabric is attached to the top of the shade. A batten at the top of the pliant fabric is used to hook the shade up. Strings extend through the pleated fabric to a slat located between the pleated fabric and pliant fabric. Tension means at the base pulls the strings down to collapse the pleated fabric. The pliant fabric covers the collapsed pleated fabric and base.

Abstract: A self-loading transport for round hay includes at tilt platform hinged to a transport platform. Round bales of hay are captured onto the tilt platform when it is in an upright position. Then, movement of the transport forward will raise and level the tilt platform with a bale of hay on it. When the tilt platform is in its full erect position, the bale of hay will roll forward from the tilt platform onto the transport platform. A rocker on the tilt platform aids in the smooth motion of the tilt platform and the rear of the transport platform from the transport position to a tilt position with a tilt platform in upright position. When the bales have been transported to the desired location, they are unloaded from the transport by permitting individual trays carrying the bales in transport on the transport platform to rotate upon the transport frame.

The rubber mud flap is clamped securely in place by nonaligned lugs on the back plate and face plate. A cam wrench is provided to press the face plate down at the post end.

Abstract: A transcatheter occluding intracardiac defect device comprises a folding poly-urethane foam with Teflon coated wire skeleton, introducible into a long vascular sheath and automatically unfolded upon delivery in the distal to the defect cardiac chamber. A two mm string loop is attached to the center of the occluder, while the loop is closed by a 1 mm knot. A loading wire comprises a Teflon hollow wire and a double mono-filament thread which carries the occluder on the one end and is tied on the other end. An occluder-holder comprises a rhomboid poly-urethane foam with Teflon coated wire skeleton and a "rubber" piece sutured in the center. The occluder-holder is advanced over the loading wire axis and through the long sheath in the proximal to the defect cardiac chamber and is pushed against the occluder till it is securely buttoned. The distal end of the loading wire is cut and the hollow wire is pulled out over the double thread. The thread is pulled as a single strand and therefore the device is released.
