Abstract: A method for affixing covering products to building structures is described. The covering product includes a thermoplastic membrane, a layer in which a fabric that includes an adhesive coating, and a release liner. The layer is affixed to a primary surface of the membrane. After the covering product is transported to the building structure, the release liner is removed, and the covering produce is adhered to the building structure.

Abstract: A roofing system in which a thermoplastic roofing membrane is affixed to a roof deck can be finished by a method in which two or more types of roofing peripherals are provided to the roof deck. Each of the peripherals includes adhesive on at least some portion thereof, and the adhesive is protected by a release liner. The release liner is removed from each of the peripherals, and the peripherals are affixed to the roofing system.

Abstract: Condensate formed on a horizontally oriented multi-poise evaporator coil is caught between a top coil slab and a bottom coil slab using a splitter, and is directed to a condensate pan located under the bottom coil slab, using at least one splash guard.

Abstract: A casing assembly suitable for use in a heat exchange assembly comprises a first panel including a first bottom portion, a second panel including a second bottom portion, and a third panel including a third bottom portion. The second bottom portion is interlocked with the first and third bottom portions.

Abstract: A condensate pan insert for an evaporator assembly is configured to snap onto a condensate pan to prevent condensation blow-off in a down flow application. The condensate pan insert comprises a cover member, a snap member, a first wing member, and a second wing member. The snap member is coupled to the cover member and configured to engage with the condensate pan. The first wing member is insertable between a first surface of the condensate pan and a bottom of a first evaporator coil slab. The second wing member is insertable between a second surface of the condensate pan and a bottom of a second evaporator coil slab.

Abstract: Condensate formed on a vertically oriented multi-poise evaporator coil is directed from a coil slab to a shield configured to attach to a bottom of the coil slab. The condensate is then drained out of the shield and into a condensate pan.

Abstract: A condensate pan for an evaporator assembly comprises a first pan member, a second pan member, and a third pan member. The first pan member has an outer wall and an inner wall, wherein a secondary channel is disposed along the outer wall. The second pan member also has an outer wall and an inner wall, wherein another secondary channel is disposed along the outer wall. The third pan member is coupled to the first and second pan members. The secondary channels of the first and second pan members are connected to a drain channel disposed along a front side of the third pan member.

Abstract: A water heater is shown having a closed metal tank with an upwardly mounted combustion chamber and burner/blower assembly. Curved fire tubes convey the products of combustion from the chamber to an exterior mounted flue assembly. The closed tank is enclosed by a rotomolded jacket. A support stand with vertically arranged support legs supports the tank in a normally vertical position but also allows the tank to be pivoted to a horizontal position on the support stand for maintenance or repair operations.

Abstract: A preformed, self adhering single ply roofing membrane including a water impermeable membrane; a pressure sensitive, hot melt adhesive adhered to one side of the water impermeable membrane, and a release liner on the side of the pressure sensitive, hot melt adhesive opposite of the water impermeable membrane.

Abstract: A multilayer film structure, including (i) a core layer, wherein the core layer comprises a propylene polymer and is beta-cavitated, and preferably comprises a beta-nucleating agent and (ii) a first skin layer, wherein the first skin layer comprises a polar polymer. Optionally, the film further comprises a first intermediate layer (iii) between the core layer (i) and the first skin layer (ii). Embodiments may have the advantage of the benefits of a beta-cavitated film without the typical increase in permeability or water vapor transmission rates typically associated with beta-cavitated films.

Abstract: A high efficiency heat exchanger is shown which can be incorporated into a finned tube water heater. The heat exchanger has a pair of flow manifolds each having a water inlet and a water outlet and a series of connecting openings. Circular flow tubes have connecting ends which fit within the connecting openings of the manifold so that the tubes are arranged in a stacked fashion to form a tube bundle. When incorporated into a water heater, a burner communicates with the interior space within the stacked tube bundle for producing products of combustion for heating water flowing in the flow tubes. The flow tubes have external fins which are crushed to form upper and lower flat stacking surfaces for stacking the tubes to form the tube bundle. The fins are also crushed to form angled baffled surfaces about a external periphery of the tubes. The baffle surfaces serve to retain heat from the products of combustion of the burner which are released into the interior space within the stacked tube bundle.

Abstract: A three-dimensional, non-crosslinked, linear or branched graft polymer matrix suitable for microassays comprises one or more active chemical moieties having inherent specificity for binding to a chemical, biochemical, or biological probe or target, the moieties being permanently attached to and distributed throughout the graft polymer matrix, optionally including one or more probes.

Abstract: A process for the formation of a purified anhydrosugar alcohol is disclosed, whereby the resultant purified anhydrosugar alcohol has a purity of at least 99.8% and is substantially colorless. The anhydrosugar alcohol is purified by distillation, recrystallization from methanol, ethanol or ethylene glycol, melt recrystallization, or a combination thereof. Preferably, the purification is by distillation followed by recrystallization from methanol, ethanol or ethylene glycol. A test for determining the purity of the anhydrosugar alcohol is disclosed, wherein the color of the anhydrosugar alcohol after annealing at a temperature of at least 260° C. for at least four hours is examined. Alternatively, purity can be determined by examination of ultraviolet (UV) transmittance of the purified anhydrosugar alcohol at various wavelengths.

Abstract: A process is described for continuous production of anhydrosugar alcohol by continuous introducing of sugar alcohols and/or monoanhydrosugar alcohols into a reaction vessel and dehydration in the presence of an acid catalyst and solvent in which the resultant reaction product is soluble. Water and the solvent having the dissolved reaction product are each cointinuously removed from the reaction vessel. The reaction product is separated from the removed solvent and the product is optionally purified to a purity of 99.0% the solvent is recycled in the reaction vessel.
