An improved wall panel system is disclosed. The system includes wall panel assemblies, each assembly having a pair of side frame members having slotted channels, top and bottom steel tubes and fork connectors for attachment to the side frame members, a top cap, lower metal supports and a plastic base rail channel and cover. The system also includes a universal connector post, a universal I-beam shaped connector, a universal bracket, a variable height bracket and adjustable corner and end caps. The corner and end caps are scored to allow removal of cap walls resulting in an inventory of fewer parts and system versatility. A removal tool is also disclosed.

A protective covering is described comprising at least one microporous film attached to a functional layer, the protective covering capable of inhibiting the passage of toxic substances therethrough. Preferably the functional layer is an adsorptive layer contained between two oleophobic, microporous films. Additional shell and backer layers may be added to the construction forming a protective covering having good durability, flexibility and high moisture vapor transmission.

The invention discloses a discloses a method for monitoring the corrosion cracks of reinforced concrete based on distributed optical fiber sensing technique. The method comprises the following steps: periodically detecting the polarization current of a steel bar and a stainless steel segment embedded in a sensor by an electrochemical work station to determine the initial corrosion time of the steel bar; monitoring the optical fiber strain by the distributed optical fiber sensing technique in real time through using sensing optical fibers surrounding the steel bar and laid in the sensor to deduce the corrosion expansion or corrosion crack stage of the reinforced concrete; and determining the corrosion expansion or corrosion crack degree by a calibration curve. The invention also discloses a sensor for executing the above method. The sensor can be used for monitoring the total corrosion cracking process of reinforced concrete at any position without damaging the structure of the concrete by monitoring the polarization current and the sensing optical fiber strain of the corroded steel bar, and can determine the corrosion crack stage and the degree of the reinforced concrete. The sensor is used for monitoring and evaluating the durability of reinforced concrete structure in the field of civil engineering.

A tool container comprising two housing members and an insert. The two housing members are pivotally coupled with one another for opening and closing with respect to one another. At least one housing member defines a cavity for receiving tools. The cavity is defined by a base and a wall extending from the base. At least one of the wall and the base include a plurality of first retaining features. The insert is operable to retain at least one tool. The insert has a surface with a plurality of second retaining features operable to cooperate with the first retaining features to secure the insert at one of a variety of positions within the housing members. The insert includes an elastomeric portion operable to engage and retain the tool.

A cooking oven is configured for use with a separate heat source such as a gas grill having one or more burners. The oven includes a housing defining an interior cooking area. A grill engaging element extends from the housing for supporting the housing on the grill over the heat source. The grill engaging element defines a passage leading to an opening in a bottom of the housing, permitting heated air to flow from the heat source into the interior of the oven. The oven has a door providing access to the interior cooking area, as well as a vent leading from a top of the housing. The cooking oven is configured to be located over burners of the grill for cooking food items.

The present invention provides a watch band construction which includes a top layer, a bottom layer and an insert. The top and bottom layers each have an aperture provided proximate to the tip ends thereof. The insert is positioned between the top and bottom layers within the apertures and is stitched to the top and bottom layers to secure the insert between the top and bottom layers. The insert provides the tip for the watch band, as well as the holes through which the buckle prong extends. The tip may be formed with raised portions and the holes may be formed with angled walls at the bottom of the insert. The insert is formed with a curve bias along both a length and width thereof. The insert is formed of a sturdy material, such as resin, such that it is durable and long lasting in the areas of high wear.
