摘要： Described herein is a method for recycling aluminum alloy wheels. The method includes the steps of providing a feed of aluminum alloy wheels of a particular alloy; fragmenting a quantity of the aluminum alloy wheels into a plurality of fragments; subjecting the plurality of fragments to shot blasting to remove surface impurities from the plurality of fragments to produce a plurality of shot blasted pieces; separating the plurality of shot blasted pieces into a plurality of larger shot blasted pieces and a plurality of smaller shot blasted pieces; and, estimating a composition of the plurality of larger shot blasted pieces by selecting multiple shot blasted pieces from the plurality of smaller shot blasted pieces and then measuring the composition of the multiple shot blasted pieces.

摘要： A cutting device using an ultrahigh pressure (UHP) hose carrying UHP fluid is designed to be inserted into a pipe or tube and cut the same from the inside out. In one example, the cutting device is for insertion into a wellbore for cutting the casing of the wellbore from within the wellbore with a revolvable UHP hose. The cutting head which effectuates the cut may be centered by a centering device that is generally conical in shape such that a portion of the centering device remains exterior to the pipe or tube as the UHP revolves during the cutting action.

摘要： Apparatuses, components, methods, and techniques for selectively texturing concrete surfaces are provided. An example method of providing a surface portion of an architectural precast concrete wall panel with an abraded texture is provided. The method includes a step of spraying a surface portion of an architectural precast concrete wall panel with an aqueous-based particulate abrasive mixture under conditions adequate to at least partially abrade the surface portion. An example sprayer system for abrading a concrete surface is also provided. The system includes an aqueous-based particulate abrasive mixture dispenser including a spray nozzle arrangement. The system also includes a material communication assembly in abrasive flow communication with the aqueous-based particulate abrasive mixture dispenser. The system also includes a dispenser positioning arrangement.

摘要： A method of prepping a cylindrical inner surface of a bore using a high-frequency forced pulsed waterjet apparatus entails generating a pressurized waterjet using a high-pressure water pump, generating a high-frequency signal using a high-frequency signal generator, applying the high-frequency signal to a transducer having a microtip to cause the microtip to vibrate to thereby generate the high-frequency forced pulsed waterjet, and rotating the rotatable ultrasonic nozzle inside the bore to prep the inner cylindrical surface of the bore using the high-frequency forced pulsed waterjets exiting from the angled exit orifices of the rotatable ultrasonic nozzle.
