Abstract: A method and apparatus for installing roofing shingles on a roof deck in a top-to-bottom manner is disclosed. Engineered battens am positioned and installed on the roof deck in a bottom-to-top manner. Each batten has a female mating area which allows complementary shingles to be securely attached to the battens by sliding a corresponding mating portion of a shingle into the mating area of the batten resulting in a snap-fit engagement which secures the shingles onto the roof deck without nails. The method and apparatus have several unique advantages, such as allowing shingles to expand and contract (“breathe”) without buckling and/or tearing when the ambient temperature fluctuates. In addition, since the manner of installation is from top-to-bottom, this allows roofers to use the rows of nailed battens as safety scaffolding improving roofers' traction and ultimately enhancing their safety while performing this inherently dangerous job.

Abstract: A composition for catalysis of a Haber-Bosch process to produce ammonia; a process employing the composition and an anion vacant lattice for use in the process. The composition comprises an anion vacant lattice and a Haber-Bosch catalyst (e.g. Fe or Ru). Suitable anion vacant lattices include oxynitrides and oxides, which may be doped or undoped, including CeaMbO2-xNy??(Formula III) M is one or more elements with a valence lower than 4. “a” and “b” are independently in the range 0.05 to 0.95, with the proviso that “a” and “b” together sum to 1 (approximately). X is greater than 0 and less than 2. Y is greater than zero and less than or equal to X.

Abstract: The food processor apparatus comprises a spill-proof cutting surface and includes a cutting surface and a flexible flange attached to the cutting surface. The flexible flange is bendable and creates a raised rim around the cutting surface. The flexible flange is itself liquid-proof and is attached to the cutting surface in a liquid-proof manner.

Abstract: Disclosed is a coated synthetic shingle that exhibits increased resistance to ultra-violet radiation. The shingle is useable for roofing applications and includes a substrate having a substrate surface and a base coat that is applied to the substrate surface. The base coat preferably includes a first fluoropolymer component. The shingle can also include a top coat that is applied to the base coat. The top coat preferably includes a clear acrylic coating. A method for manufacturing the shingle is also disclosed.

Abstract: A shingle includes a body having an upper end, a lower end, a top surface, a bottom surface, a first side and a second side. The body has a width defined as the distance between the two opposing sides, a length defined by the distance between the upper end and the lower end. In a preferred embodiment, the shingle also includes a side wall that extends downward from the body adjacent one of the sides and extends the length of the shingle. The side wall preferably includes an angular projection disposed toward the upper end.

Abstract: A roller bar security device includes a longitudinally extending tubular member having first and second ends and a plurality of rigid overlapping outwardly extending blades each of which has a generally triangular shape with a base mounted on the tubular member and a sharp point at its apex. The blades are fixed to and extend around and along the tubular member with the apexes of alternate longitudinally spaced blades facing in generally opposite directions. A mounting bracket and bearing are provided for rotatably mounting the tubular member and blades on top of a wall or the like so that the sharp points and edges will deter a potential intruder from climbing over the security device.

Abstract: Methods and kits are provided for the detection and quantification of a protein. The methods comprise immobilizing the protein of interest on a substrate, the protein comprising an epitope and another portion, contacting the immobilized protein with a labeled ligand that binds to the epitope to yield a detectably labeled protein, detecting the detectably labeled protein, and quantifying the detectably labeled protein, and the kits comprise a sample of a standard protein, wherein the standard protein comprises an epitope and the sample is of a known concentration of the standard protein, and an aliquot of a labeled primary antibody having specificity for the epitope.
