A device for scrubbing carbon molecules from the ambient atmosphere includes a housing, a carbon-capture filter, and a holding mechanism to hold the device in operable association with an automobile. A housing may be perforated and constructed to removably hold a filter. A filter can include a hydroxide chemical compound in granular form. A holding mechanism may anchor the device to a grille, under-hood element, or in operable association with a tailpipe of an automobile. Sometimes, the device includes a color-changing indicator to indicate end-of-life of a filter. A decorative emblem may be included to obscure the device from casual observation by a passerby.

A filter head assembly includes a filter head and a threaded bayonet connection adapter having a rotational position tolerance improving retainer ring. The rotational position tolerance improving retainer ring providing for and enabling the critical further deformation of the rotational position tolerance improving retainer ring beyond the predetermined final assembly torque to achieve the required critical final rotational position of the threaded bayonet connection adapter for the correct operation of the open and locked position indicators on the filter head.

In another aspect, a method of forming a material is disclosed, including: forming a periodic structure including a plurality of unit cells, the plurality of unit cells having a respective plurality of shared nodes, wherein each of the plurality of unit cells has a plurality of members forming an open cell volume; and associating a matrix material with the periodic structure. Matrix material selection, composition, manufacturing, interfacial bonding modification, and post-treatments of the periodic structure-matrix material composites are disclosed.

A method of cleaning a regenerative filter having a filter housing having inlet and outlet zones, a fluid path provided between the inlet and outlet zones, and a plurality of filter elements each having an outer surface filter media applied thereto and functioning to filter particulate or contaminants from the fluid path, the method comprising draining all fluids from the filter housing, refilling the filter housing with fluid to an optimum level, and initiating a cleaning sequence of the filter housing with the fluid at the optimum level. The cleaning sequence can comprise agitating the tube sheet, initiating a pump to effectively air scour for a first predetermined amount of time, dwelling for a second predetermined amount of time, and repeating the agitating, initiating, and dwelling until a third predetermined amount of time is complete.

Disclosed are an oil separation apparatus (70) and a horizontal vortex compressor (1) comprising the oil separation apparatus (70). The oil separation apparatus (1) comprises a support (71) and a filter member (72), wherein the support (71) is generally cylindrical and comprises a cylindrical wall (712), the filter member (72) is arranged on the cylindrical wall (712), and the cylindrical wall (712) is provided with an opening (711, 713) used for working fluid to pass through; and the filter member (72) is generally cylindrical, and comprises an inner and an outer holding member (74, 76) holding inner and outer contours of the filter member (72) and end holding members (75a, 75b) provided on axial ends of the filter member (72). The oil separation apparatus (70) can increase the oil level of lubricating oil in the compressor (1), reducing disturbance in an oil tank and reducing oil circulation efficiency.

A filter device provides designs that permit variable levels of solid particle removal. The filter device retains the particles in the filter medium when removed, thus avoiding the re-entry of the particles when the power system has cooled down which occurs in conventional filters currently in use. The filter device incorporates elements made from stainless steel for (a) durability and high mechanical strength to endure high continuous flow pressures; (b) ductility so as to be pleated and shaped into a cylinder; (c) corrosion and high temperature resistance; (d) particulate removal in the range of 4-20 microns depending on the desired performance characteristics; (e) high percentage of contaminant removal; and (f) recyclability and reusability.

A filter device has a support tube, which has an inner face and an outer face and which forms an interior adjoining the inner face, into which interior an inlet opening leads, the support tube having through-openings, which connect the interior to a surrounding space adjoining the outer face of the support tube, and a first filter element, which has an inner face and an outer face. The first filter element is disposed in the interior of the support tube and the outer face of the first filter element is adjacent to the inner face of the support tube. A support body is disposed in the interior of the support tube and the support body adjoins the inner face of the first filter element. The filter device can be disposed in a filter housing and, in particular, can also be used in separating water from hydrocarbons.

According to one aspect of the present disclosure, a filter assembly includes a filter housing including a housing inlet and a housing outlet, and a filtering section located downstream of the housing inlet and upstream of the housing outlet. The filtering section includes a first filtering portion, a second filtering portion, a wall longitudinally separating the first filtering portion and the second filtering portion, a filtering outlet, and a valve located in the filtering outlet. The valve includes a closed condition and an open condition, and wherein, in the valve closed condition the valve blocks flow from the second filtering portion to the housing outlet.
