Abstract: Methods of making 1-alkylindazoles are described. The methods involve reacting a 2-alkylaminobenzonitrile with a nitrosating agent followed by reduction-cyclization of the resulting nitrosamine to form a 1-alkyl-3-aminoindazole. The 1-alkyl-3-aminoindazole can be deaminated to form a 1-alkylindazole which ultimately can be used to form desired indazoles which are preferably pharmaceutically active products. The process of the present invention further permits the formation of enantiomerically enriched or pure indazoles such as aminoalkyl indazoles.

Abstract: Methods of making roofing products. One such method includes (a) creating a mixture having a filler and a polymer; (b) forming a sheet from the mixture; (c) cooling the sheet; (d) embossing the sheet; (e) forming multiple roofing products from the sheet; and (f) bundling at least some of the roofing products. Steps (a)-(f) are performed using an automated procedure. Another of the methods involves (a) creating composite roofing products using mold cavities; (b) using a robot to transfer some of the roofing products from some of the mold cavities to a conveying system; and (c) stacking together at least two of the roofing products that have different colors or different surface configurations.

Abstract: Methods are provided for coating glass waste. A mixture including a universal resin, a curing agent, a flow modifier, and a colorant is applied to the glass waste. The glass waste is then cured. In some embodiments, the mixture is sprayed onto the glass waste. In an alternative embodiment, the mixture is mixed with the glass waste.

Abstract: A method of making a roofing product such as a shingle is provided. One such method includes creating a mixture having at least a polymer and a filler, forming a sheet from the mixture, cooling the sheet, embossing the sheet, forming multiple roofing products from the sheet and bundling at least some of the roofing products together. This method is performed using an automated procedure. Another method of the present invention involves creating a composite roofing product using mold cavities, using a robot to transfer some of the roofing products from some of the mold cavities to a conveying system, and stacking together at least two of the roofing products that have different colors of different surface configurations.

Abstract: A roofing shingle with a laying line that facilitates the alignment of an overlying course of shingles with respect an underlying course of shingles is provided. The laying line is located on a front surface of the shingle and has a width such that the laying line is exposed when an edge of another shingle is placed in contacting proximity with the laying line. The shingle may also have a scale and one or more nibs that protrude from the sides of the shingle that assist in aligning the shingles in the second course with the shingles in the underlying course. The shingle may also include nailing zones located on the front surface of the shingles provide a location for fastening the shingles to the roof. A method of laying the shingles of the present invention on a roof is also provided.

Abstract: Roofing products with improved laying lines. In one embodiment, the roofing product includes a laying line oriented lengthwise on one side of the roofing product, and the laying line has a width of at least ⅛ inch.

Abstract: Methods are provided for coating glass waste. A mixture including a universal resin, a curing agent, a flow modifier, and a colorant is applied to the glass waste.

Abstract: Methods are provided for coating substrates. The mixture includes a universal resin, a curing agent, a flow modifier, a colorant, and a thermochromatic compound, a phosphorescent compound, or a luminescent compound. The mixture is coated onto a substrate. Coating can be achieved by mixing the mixture with a liquid form of the substrate, spraying the mixture onto the substrate, brushing the mixture onto the substrate, or submersing the substrate into the mixture.

Abstract: An endless power transmission belt comprising a tension section, a cushion section and a load-carrying section disposed between the tension and the cushion sections, and at least one drive surface having fabric layer bonded to an outer surface of the belt is coated with a layer of polyvinylidene fluoride.

Abstract: A flat, sealed case for a secondary cell includes a flat shallow plastic base and a thin, flat plastic cover the periphery of which is sealed to the base and includes at least one internal restraint to prevent bulging of the flat cover and base upon a build-up of internal pressure within the cell case, for example during recharging.

Abstract: A resealable vent for a secondary cell having a flat plastic case including a resilient ball seated in an apertured passage with a predetermined amount of compression and adapted to unblock an opening in the passage and vent gaseous material upon an excessive build-up of internal pressure within the cell case, for example, during recharging at an accelerated rate.
