An EMI and RFI shield mounting system (24) includes a compartmented EMI shield (21) constructed of a vacuum metallized thermoform (22) having upright hollow walls separating and surrounding the compartments (13). The shield (21) conforms to the interior of a housing (20) for electronic equipment (30), with the upright walls (29) overlying ridges formed in the interior of the housing (20). A compressible gasket (25) is placed between the ridges of the housing and the inner reaches of the hollow walls (31) of the shield (21). The free sides of the walls (29) of the shield (21) may be abutted against ground traces (46) on a printed circuit board (32) on which the shield (21) and housing (20) are placed. The gasket (25) urges the metallized free edges of the walls (20) of the shield (21) against the ground trace (46) of the printed circuit board to provide electrical conductivity between the printed circuit board and the shield (21). Dimples (60), tabs (52) or protruding punctures may be formed in the free sides of the walls (29) to ensure conductive contact with the ground trace (46).

A capacitive liquid level sensor is integrated with a drinking vessel or the like, and provides a sensory output signal having a characteristic that varies as a function of liquid level in the vessel. The vessel can have a hollow wall with conductive plates placed or affixed on a back surface of an inner wall panel of a hollow wall or protected by a handle. The plates form a capacitor for which liquid displacing air in the vessel provides at least part of the dielectric. A timing circuit is responsive to the capacitance of the plates, which changes when the liquid level displaces air from around or between the plates and changes the effective dielectric constant. The circuit can produce a preferably non-visual signal that varies over a range of liquid levels, or can change when the level passes a threshold level.

The invention relates to the field of precast concrete structures, in particular to a vertical connection structure for precast concrete shear walls and a construction method. Steel bars in vertical distribution and steel bars in horizontal distribution are arranged on two sides of each vertical through hole of each precast porous shear wall which is a porous hollow wall. At a construction site, vertical connection between an upper precast porous shear wall and a lower precast porous shear wall is realized by arranging connection reinforcement cages and concreting or grouting mortar into floor cast-in-situ zones and vertical through holes of the precast porous shear walls. By the shear wall and the connection method, dead weight of a wall body is reduced, and cost is reduced as compared with that of a reinforcement sleeve grouting connection method. Compared with an existing core-pulled porous hoop-confined concrete reinforcement grouting anchor lap joint method or a metal corrugated tube porous reinforcement grouting anchor lap joint method, the vertical connection method has the advantages that hole quantity is reduced to prevent cracking of porous walls, and transport is facilitated due to the fact that the vertical steel bars in the precast walls do not protrude outside.

The invention relates to a method for manufacturing a composite light wall made from WPC material/ rigid foam. The method comprises two procedures of the molding of the outer layer of a hollow wall member and the on-site filling of a core layer. After being mixed and plasticated, wood fiber material, polymer material, various accessory ingredients and additives are made into the granular WPC material by a screw extruder. After being added into the screw extruder, the granular material is made into the outer layer of the wall member. With the completion of processes of hand piece, vacuum cooling, shaping, traction and cutting, the outer layer of the hollow wall member is obtained. A froth placer is used for performing on-site rapid rigid aeration for polyurethane material that is filled into the outer layer of the wall member, thus making a composite light wall plate made from the WPC material/rigid foam. The method for manufacturing the composite light wall made from the WPC material/rigid foam avoids the problem that the core layer and the outer layer of the wall member can not be extruded simultaneously and the core layers with different densities can be filled and foamed according to the strength of the wall member and on-site requirements, thus ensuring the transverse compressive strength of the wall member. The method for manufacturing the composite light wall made from the WPC material/rigid foam is convenient and flexible and has wide application range.

A system and method for treating a mold-infected building with hollow walls, ceilings, or floors using a relatively high concentration of ozone. The system includes an ozone generator that includes inlet and outlet ports that supply a constant, relatively low pressure flow of ozone to a continuous space formed inside a wall, floor, or ceiling. Special connectors are used that are inserted into two port openings formed on the wall that enables ozone to slowly flow into and out of the continuous space formed in the wall. The concentration of ozone and rate of flow is sufficient so that the ozone has sufficient time to kill the mold spores without dislodging them.

A retrievable toggle bolt for mounting an object on a drywall or other hollow wall structure includes a headless bolt having a threaded shaft with a terminal portion for insertion through a hole in the drywall. A toggle is engaged by a pivot-and-slide engagement configuration with the terminal portion of the headless bolt so that the toggle is free to pivot relative to the headless bolt about a pivot axis substantially perpendicular to the direction of elongation and the pivot axis is slidingly displaceable along part of the toggle roughly parallel to the length. The pivot-and-slide engagement configuration links the toggle to as to rotate together with the headless bolt about an axis parallel to the direction of extension. The result is a toggle bolt which can be switched between an insertion/removal state and a locked state by simply turning the headless bolt through a half-turn about its axis.
