Abstract: A segmented insulative device and related kit for insulating components of a thermal distribution system. The kit includes a sheet of segmented insulation formed by a composite layer of segmented, flexible, pre-sewn insulation that is easily cut to size in the field using scissors, utility knives or other simple, hand-held cutting devices. The kit also includes two-sided hook-and-loop straps as fasteners, also easily cut to length, using hand-held devices. The segmented insulation and the hook-and-loop straps are attached to one another in the field using a stapler or other hand-held attachment device. This provides an installation kit that an installer can use to provide a versatile insulation in the form of the assembled segmented insulative device. The segmented insulative device lends itself to quick customization on-site rather than requiring costly off-site manufacture or pre-assembly and subsequent quick installation on the pipe component requiring thermal installation.

Abstract: A suction strainer is provided for use in a pumping system of the type wherein a suction line provides fluid flow to a pump and wherein the suction strainer is connected to the suction line for removing solids or aquatic life from a flow of fluid being drawn into the suction line, The suction strainer comprises a hydrofoil and an internal conduit. The hydrofoil is formed with opposed filtering surfaces having apertures formed for the passage of fluid to an internal volume. The internal conduit is formed with a surface extending the length of the conduit and having apertures formed for the passage of fluid from the internal volume of the hydrofoil to the internal volume of the conduit.

Abstract: The invention provides an apparatus (10, 300) incorporating a lithographic tool (20) for printing a pattern from a mask (35) onto a substrate, for example a wafer (190), together with a substrate angle measuring tool (100, 310) employing X-ray diffraction techniques for determining substrate crystallographic orientation. The apparatus (10, 310) is calibrated so that the mask (35) is correctly angularly orientated with respect to the measuring tool (100, 310). When a new substrate (190) is loaded into the apparatus (10, 310) for having the pattern from the mask (35) printed thereonto, the apparatus (10, 300) angularly aligns the substrate (190) relative to the measuring tool (100, 310), thereby also aligning it angularly to the mask (35).

Abstract: The chlorine overvoltage of carbon and graphite electrodes is considerably and permanently decreased by treatment of the electrodes with nitric acid. The treatment also causes an apparently permanent decrease in the amount of oxygen produced at the electrode coincident with the chlorine generation.

Abstract: Delignification of lignocellulosic material, such as wood, straw or bagasse, with a soda pulping liquor containing a diketo hydroanthracene selected from the unsubstituted and lower alkyl-substituted Diels Alder adducts of naphthoquinone and benzoquinone and a nitro aromatic compound selected from mono and di-nitrobenzenes and the amino, carboxy, hydroxy and methyl derivatives of said nitrobenzenes.
