Abstract: This invention is a kit and method for testing golf balls to determine if the center of gravity is the center of the golf ball. The kit uses a liquid, such as water, having a densifying agent to increase the density of the liquid solution so a golf ball will float when placed in the solution. A wetting agent is also included in the solution to decrease the surface tension. If a golf ball, having a center of gravity at other than the center of the golf ball, is placed in the solution, the light side of the ball will rotate to the top. The light side is then marked with an indelible marker. An axis through the center of the golf ball and the mark also includes the center of gravity of the golf ball. Thereafter, the axis of the golf ball including the mark, should always be placed perpendicular to the plane of the striking surface.

The slidable trays are stacked either vertically or horizontally with the items contained thereon being visible through a locked sliding glass door of the display case. Each of the trays has rollers to aid the movement of the trays along grooves inside the display case. Knobs extend from the side of the trays through slots to the outside of the display case to allow movement of the trays by customers to view items contained on each tray. A three-fourths length thin sliding bar moves with each tray to cover the slots in the side of the display case thereby preventing pilferage through the slots by customers.

Abstract: The present invention is a projectile type demolition tool. A projectile with an enlarged upper cross-sectional area is slideably mounted within and extendable from an inner cylinder. The lower portion of the projectile is extendable through a guide connected to the bottom of the inner cylinder. Upon pressing a working end of the projectile against a work piece to be broken, the projectile recedes upward in the inner cylinder until the enlarged upper area moves above a source of low pressure gas connected through the inner cylinder. The low pressure gas continues to move the projectile upward in the inner cylinder to a cocked position. In the cocked position, a reduced area upper portion of the projectile acts against a moderately high pressure gas injected into a combustion chamber. Thereafter, a high pressure gas is created by an internal combustion in the combustion chamber, which high pressure gas drives the projectile downward into the work piece.

Abstract: The present invention relates to heat pumps which include a freeze-up prevention device for use during the heating cycle. The heat pump consists of the normal compressor which connects by means of a four-way valve to an inside coil and an outside coil. An expansion valve and appropriate check valve allow the flow of refrigerant between the inside and outside coils. During the heating cycle, the inside coil is the condenser and the outside is the evaporator. The freeze-up prevention device is a small insertable unit immediately prior to the evaporator which allows the refrigerant to flow therethrough. The insertable unit has a heating element operable by a thermostat attached to the outside coils with the thermostat closing a switch to allow current to flow to the heating element when an icing condition is sensed. The insertable unit, via the heating element, transmits heat directly to the refrigerant thereby preventing freeze-up of the evaporator coil.

Abstract: An impact drilling apparatus has an anvil inside a casing for receiving impact blows from a hammer. The lower end of the anvil is threadably connected to a drill bit having an external load bearing shoulder. On the lower end of the casing is attached a driver guide sub which extends downwardly around the threaded connection between the drill bit and anvil to bear on the external load bearing shoulder for transmitting down weight to the bit and simultaneously counteracting lateral forces acting on the bit and anvil. A spline connection is provided between the driven guide sub and the anvil. In the off bottom position, a shoulder of the anvil comes to rest against the top of the driver guide sub which stops the reciprocating action of the hammer while drilling fluid continues to flow.

Abstract: The present invention is a system for treating sewage waste commonly called sludge. An aerator shears the solid particles while simultaneously adding oxygen to the sludge. After being pumped through the aerator, the sludge exits into a large tank. The sludge in the tank is continually circulated, drawn from the bottom of the tank and pumped through the aerator. As additional sludge is periodically added, supernatant water is removed through an overflow line of a stilling well in the center of the tank. After a lengthy period of time, part of the sludge in the bottom of the tank will be withdrawn and moved to the drying beds. With some modifications, existing anaerobic systems may be changed to the present aerobic system for a much greater capacity. Entire collection and waste treatment plant facilities may be designed utilizing the aerators at various stages.

Abstract: This invention is a fuel filter for use in a fuel line to remove particles from fuels that are subject to freezing under certain operating conditions. The fuel filter has a screen slideably carried on a piston located in an elongated housing. Fuel enters one end of the housing, strikes the piston and flows outwardly through the screen, around the piston, through holes in a spacer and out the other end of the housing. Upon freezing in the screen the fuel or water particles suspended therein, the pressure of the fuel will move the screen and piston along the axis of the housing to open a bypass around the screen. When the frozen particles melt or fuel pressure is removed, a spring returns the piston and screen to their normal position. Solid particles previously removed from the fuel before freezing remain trapped in the screen.

Abstract: The present invention is a secondary recovery system normally used for retrieving oil from the producing zone after the bottom hole pressure has decreased so that artificial lift is required for production. An accumulator is positioned in the lower portion of the casing where oil will accumulate from the producing zone. A standing valve is located in the bottom of the accumulator to prevent oil collected therein from leaving the accumulator. Above the accumulator is located a free floating piston having passageways therethrough. By proper control of the pressure line from the surface, oil is gradually moved through the free floating piston into a production tubing thereabove. Next, again in response to surface control, the free floating piston and oil collected thereabove is moved to the surface of the well by a rapid pressurization of the accumulator. Thereafter, pressure is exhausted from the accumulator allowing the piston to drop back to its lowermost position immediately above the accumulator.

Locking holes are contained in both the rotatable plate and each pivotable bar contained thereon to lock the bar into a position covering each of the respective holes. A horizontally slidable locking bar which is in the same plane as the gate, slidably extends through a gatepost with one end thereof extending into a hole in a fencepost.

Abstract: This invention involves the orthodontic movement of live teeth in the mouth by using the forces of magnets. A magnet is attached to the teeth by conventional methods such as adhesive bonding or dental appliances. The magnets are placed on the teeth in such a manner to employ the attraction and repulsion characteristics of a magnetic field. These forces may be employed to align teeth, tilt teeth, move root positions and angulations, torque teeth, and erupt impacted or partially impacted teeth into the correct position in the mouth. The technique may be used alone or in combination with other conventional orthodontic techniques for either major or minor tooth movement. The magnets may be attached anywhere on a tooth, but preferably in an inconspicuous position. The magnets themselves may have tapered edges to insure the teeth move to the proper position.

There is a channel through the plug coaxial with the main channel of the housing and there is a bored opening along the axis of the plug so that a sphere can be inserted into the line from the bottom end of the plug. The housing has a downward extension in line with this opening in the plug so that spaces provided for one or more spheres to be received as they travel down the pipeline to the housing and into the plug. The bottom end of this extension is closed with a screw type sealed closure. Means are provided in the housing surrounding the central passage to seal tightly against the surface of the plug. The plug itself is not exactly cylindrical.

Abstract: This invention is for a lawn edger. The edger has a strong unitary base mounted on a middle row of wheels and may be tilted backwards onto a rear roller. A motor is mounted on top of the base and a handle connects to the rear of the base. A cutter extends forward of the base and is held into position by a pair of forwardly extending rods. The cutter, which turns in a direction to throw any debris forward of the edger, is driven by a belt from the motor. A spring operating against one of the rods keeps a constant tension on the drive belt. A shield surrounds the cutter and has a guide with a lower rear position extending below the cutting blade. The edger may be run on a flat solid surface without the blade striking the surface. The edger is balanced with the middle row of wheels being the approximate center of gravity. The edger can tilt forward to the cutting position or rearward against the rear roller.
