A process and apparatus for extruding aluminum into products, wherein aluminum logs are first heated to a predetermined temperature in a furnace, then are cut into billets of predetermined lengths, and then the billets, while still hot, are extruded into predetermined products in an extruder. In the process, the logs are cut into billets with a cross cut circular saw immediately after the logs are heated and before the logs are permitted to cool to a temperature below a suitable extruding temperature. The circular saw is cooled and lubricated during the cutting to as to restrain the saw from sticking in the heated aluminum and so as to maintain the temperature of the log at the cut within a predetermined range wherein the aluminum is relatively easy to cut and waste is minimized.

An aquatic sport assistance device for use in surface water sports. An inflatable device using drop-stitch construction to provide a portable but rigid platform on which a user can sit to learn surface water sports. Two floats at a spaced relation to one another create an open space between the two floats. A deck disposed upon the two floats creates an open space between the seats and the surface of the water. This allows water skis or wake boards to rest below the deck on the surface of the water for a natural sitting position. Can be used with barefoot skiing. Device has three seat pads, allowing for use with water skis and wakeboards, and allowing for use as regular or goofy foot. Handles help a user to proper position for activity chosen. Fins give directional stability, allowing device to be towed directly behind boat or along boat wake.

The method of the present invention employs a subsurface production pump to displace hydrocarbon fluid, including any and all accompanying ground water and/or earthen contaminants, from the subterranean hydrocarbon reservoir depth of an oil well to surface storage and handling facilities via the subsurface production tubing, wellhead and surface flow line. As the subsurface production pump operates, compressed gas, or a mixture of compressed gases of sufficient volume and force is fed into the lower end of the subsurface production tubing in proximity to, or at a point above the subsurface production pump to mix into the hydrocarbon production fluid column. The resultant and considerably reduced density of the subsurface hydrocarbon production fluid column provides a reduction of subsurface production pump loading with all types of subsurface production pumps, and an improvement of sucker rod fall time when sucker rod activated subsurface plunger pumps are employed. Due to the additional cubic volume of the injected compressed gas, the increased hydrocarbon production fluid and gas velocity within the subsurface production tubing and the surface flow line improves hydrocarbon fluid shear from the conduit walls and sucker rod surfaces, and prevents earthen contaminants such as sand, clay, shale, coal or other rock fragments, from precipitating, accumulating and blocking the flow of hydrocarbon production fluid within the subsurface production tubing and the surface flow line.

A boat lift braking system includes a threaded shaft driven by the boat lift motor. A torsion tube disposed about the shaft carries an interiorly threaded nut that interengages the peripheral threads of the shaft. A rotor is mounted to the nut adjacent a brake pad that is supported by a ratchet component. A pawl mechanism cooperates with the ratchet component for limiting rotation of the ratchet component in a first direction and permitting rotation of the ratchet component about the shaft in a second direction. The torsion tube is connected through a reduction apparatus to the winder of the boat lift. When the lift is at rest, a torsion spring drives the torsion tube and rotor against the brake pad and the ratchet component interlocks with the pawl mechanism to hold the lift at a desired elevation. When the motor is driven to lower the lift, the shaft is driven within the torsion tube such that the rotor momentarily disengages the pad. Immediately thereafter, the torsion spring forces the rotor back against the pad and these counteracting forces continuously repeat to provide a controlled descent. When the motor is operated to raise the lift, the shaft is driven relative to the torsion tube such that the rotor and pad interlock. The ratchet component disengages the pawl and the torsion tube turns so that the lift can be elevated.
