Abstract: A passive cooling article is disposed on a substrate to cool the substrate. The article includes an outer layer having a high absorbance in the atmospheric window region of the electromagnetic spectrum and having a high transmittance in the solar region of the spectrum. The article also includes a reflector having a high reflectivity in the solar region of the spectrum. At least one of the outer layer and the reflector includes a fluoropolymer. Micro-sized particles or surface structures may be disposed in or on the outer layer or the reflector to improve absorbance. A metallic layer may be disposed between the fluoropolymer and the substrate to be cooled.

Abstract: Contemplated devices and methods reduce heat loss and energy demand of a carbon baking ring furnace by employing a preferably internal bypass conduit that feeds a portion of a heated cooling air stream from the cooling zone directly to the flue ducts of the firing and/or pre-heat zones.

Abstract: Contemplated devices and methods reduce heat loss and energy demand in a ring furnace by heating an additional oxygen containing stream in a supplemental oxygen conduit that is thermally coupled to a flue duct of a cooling zone. The so heated additional oxygen containing stream is then fed to the firing and/or pre-heat zones to increases combustion of volatiles and to reduce fuel demand by recycling waste heat to the firing and/or pre-heat zones.

Abstract: A computer-implemented method for elevating privileges for a process may comprise: 1) determining that the process requires elevated privileges for proper execution, 2) attempting to elevate privileges for the process, 3) determining whether privileges for the process were elevated, and 4) concluding execution of the process. In one example, each step of the method may be performed by the process itself. Corresponding systems and computer-readable media are also disclosed.

Abstract: A motor driven acoustic oscillator or speaker that generates a single frequency acoustic sound. The motor driven acoustic oscillator may be used to emit low frequency (LF) sound waves that generates thrust on an object. The oscillator may be further configured to convert heat energy from a surrounding fluid medium into additional useful mechanical work.

Abstract: A fluid pressure system (S) includes a flexible diaphragm bladder (172) located inside a pressure tank (164) installed within a fluid system such as well (168). In preferred aspects, the bladder (172) can be inflated by the introduction of air and is located within a flexible confining tube (198) or confining element (298) for preventing over expansion of the bladder (172). The bladder (172) and the confining tube or element (198, 298) are free floating in and without physical connection with the pressure tank (164) in preferred forms. The pressure tank (164) includes a flexible side wall (196) to allow folding or willing of the assembled fluid pressure system (S) in preferred forms. Confining tube (198) in a preferred form is of a cylindrical configuration and arranged concentrically around the bladder (172). Confining element (298) is carried by the bladder (172) and creates a barrier extending along a chord of a cross section of pressure tank (164).

Abstract: A water pressure system includes a pressure tank installed underground within the well casing of a well. The water pressure system includes a submersible pump connected to the inlet of the pressure tank by a drop pipe. The outlet of the pressure tank is connected to a second drop pipe and in turn to a discharge pipe for distribution of pressurized water to a house or other building. A pressure switch is connected to the pressure tank for controlling the submersible pump. The pressure tank includes an outer sidewall with an inlet end and an outlet end. A flexible diaphragm bladder located within the outer sidewall is connected between the inlet and outlet of the tank. In a first embodiment, a tube extends through the center of the bladder between an inlet opening and an outlet opening. The tube has a plurality of holes therein to allow water to flow into and out of the flexible bladder. Pressurized air fills the space between the bladder and the outer sidewall to pressurize the water in the bladder.

Abstract: An air filter for a well is installed within a well casing of the well. The air filter forming an airtight seal around the well casing of the well, such that all the air that enters and exits the well must pass through the air filter. The air filter preferably includes a filter housing, at least one removable gasket and a removable filter cartridge installed within an opening extending through the filter housing. The air filter prevents dirt, dust, bacteria, gaseous chemicals, volatile organic compounds, (VOCs), insects and other air born airborne contaminants from entering and possibly contaminating the well. An air filter may also be installed within a vent pipe extending through a well seal attached to the top of a well casing of a well.
