Abstract: An air filtration apparatus includes a motor, a fan blade, an air filter, a housing, a filter cleaning assembly, and a control panel. A stator of the motor is concentrically mounted within the housing, and the fan blade is concentrically mounted to a rotor of the motor so that the air can be moved via the fan blade. The air filter is externally mounted to a rear panel of the housing to purify incoming air. The filter cleaning assembly is integrated to the air filter and is in fluid communication with the air filter so that the air filter can be cleaned when necessary. The control panel being electrically connected to the motor and the filter cleaning assembly to continuously operates the air filtration apparatus.

Abstract: Pressure transmitters mounted on a panel are arranged so as to ease and facilitate their calibration. More particularly, curved tubing portions are interposed between the drain/vent valves and transmitter bases of the pressure transmitters so as to cause the drain/vent valves to face outwardly from the panel in the same direction that pressure valves on the transmitter base face. Common fluid lines together with a pressurization valve are provided to simultaneously pressurize multiple pressure transmitters to further ease the calibration process.

Abstract: A method of recycling bonded fibrous materials, the method includes the steps of: providing pieces of bonded fibrous materials, the pieces having sizes that are adapted for suspension in a liquid; suspending the discrete pieces of bonded fibrous materials in a liquid; applying mechanical work to the liquid suspension of discrete pieces to generate hydraulic pressure and mechanical shear stress conditions sufficient to hydraulically fragment the bonded fibrous materials into fibers and fiber-like components; and separating substantially individual fibers and fiber-like components from the liquid. The method is used to produce recycled synthetic fibers and fiber-like materials that have at least one thread element composed of synthetic material having at least one irregular distortion generated by hydraulic fracture of the thread element to separate it from a bonded fibrous material while the bonded fibrous material is suspended in a liquid.

Abstract: A hydraulically entangled nonwoven fabric that includes recycled synthetic fibers and fiber-like materials having at least one thread element composed of synthetic material with at least one irregular distortion generated by hydraulic fracture of the thread element to separate it from a bonded fibrous material while the bonded fibrous material is suspended in a liquid. This material may be used as a wiper or an absorbent material. A method of forming the material includes the steps of: (a) providing a layer of recycled synthetic fibers and fiber-like materials having at least one thread element composed of synthetic material containing at least one irregular distortion generated by hydraulic fracture of the thread element to separate it from a bonded fibrous material while the bonded fibrous material is suspended in a liquid; (b) hydraulically entangling the layer to form a nonwoven web; and (c) drying the web.

Abstract: A hydraulically entangled nonwoven composite structure that includes a matrix of substantially continuous filaments; and recycled synthetic fibers and fiber-like materials having at least one thread element composed of synthetic material with at least one irregular distortion generated by hydraulic fracture of the thread element to separate it from a bonded fibrous material while the bonded fibrous material is suspended in a liquid. This nonwoven composite structure may be used as a wiper or an absorbent material.
