Abstract: A reaction pathfinder system can leverage historical chemical reaction data and determine a synthesis route in a reaction network. The reaction pathfinder system can account for various performance criteria of chemical reactions such as a highest yield for a molecule or a minimal number of reaction steps. A reaction pathfinder system receives a user request for a synthesis route including one of a user-specified molecule or a user-specified reaction. The reaction pathfinder system may then query a reaction network that has various synthesis routes and represents reactions of reactants to produce respective molecules. The reaction network may be composed of molecule nodes and reaction nodes. The reaction pathfinder system determines, using the reaction network, the synthesis route from the synthesis routes to fulfill the user's request.

Abstract: A roofing system including a roof deck and a membrane assembly secured to the roof deck. The roof deck may be a flammable roof deck. The membrane assembly includes a roofing membrane and a fire resistant sheet, the fire resistant sheet, or a portion thereof, secured to the membrane. The fire resistant sheet includes a fabric substrate and a binder.

Abstract: The present invention provides a recycled building material such as roof/Geo membrane that comprises (i) a polyolefin, (ii) a polymer containing a carboxyl group or a hydroxyl group, and (iii) a compatabilizer for the components (i) and (ii) which contains an epoxy group or an anhydride group. The present invention also provides a method of recycling building material as well as an article of manufacture such as a TPO membrane using the recycled building material. The TPO membrane has gained better physical properties such as consistent product quality, tensile strength, tear strength, wind resistance, and avoidance of tedious screening processes, among others.

Abstract: A multi-layer roofing membrane is provided including a top sheet including a co-extruded cap and inner layer and a bottom sheet. The use of a co-extrusion die allows for multi-layer sheets that reduce the need for expensive fillers in all but a cap layer of the membrane. A scrim reinforcement layer is optionally embedded in the membrane. When installed on a roof substrate, the membrane can be sealed by heat welding the seams of the membrane sheets or by other means.

Abstract: A process for preparing a multi-layer roofing or structural membrane is provided including a top sheet including co-extruding a cap and inner layer and bonding the top sheet to a bottom sheet. The use of the co-extrusion process allows for multi-layer sheets that reduce the need for expensive fillers in all but a cap layer of the membrane. A scrim reinforcement layer is optionally embedded in the membrane. When installed on a roof substrate, the membrane can be sealed by heat welding the seams of the membrane sheets or by other means.

Abstract: Broadly, the present invention provides a thermoplastic vulcanizate which can be readily processed into sheeting material for covering a roof that is both flexible and highly elastic. Where other thermoplastic elastomeric compositions have either been too stiff to act as roofing membranes or not processable due to their melt flow characteristics, the present thermoplastic vulcanizate employs a polypropylene random copolymer resin and a polyethylene random copolymer resin having about 10 to about 35 percent by weight ?-olefin co-monomer units; together with a compatibilizing rubber and a peroxide-based cross-linking agent, to provide an effective membrane for covering roofs.

Abstract: A primer tank having a nozzle assembly which uniformly distributes nitrogen or other vapor-generating gas against a primer liquid in the tank to generate a primer vapor for the priming of a semiconductor wafer substrate. The nozzle assembly includes a conduit to which is confluently attached a nozzle head having a nozzle plate. Multiple openings are provided in the nozzle plate to substantially uniformly distribute nitrogen or other inert gas against the surface of the primer liquid over a large area to generate a primer mist from the primer liquid and substantially reduce the formation of primer droplets in the tank.

Abstract: A low profile board-to-board connector assembly includes a receptacle and a detachable plug. The receptacle has a receptacle housing with a plurality of arrayed first contacts mounted therein. Each first contact has a base portion, a first solder tail portion extending outwardly from one end of the base portion for connection with a first PCB, a retention portion perpendicular to the base portion, and a free first spring contact portion bent from the other end of the base portion and extending parallel to the retention portion. The plug has a plug housing with a plurality of arrayed second contacts mounted therein. Each second contact has a U-shaped portion with a pair of legs one of which is a free second spring contact portion and the other of which is a locking portion, and a second solder tail potion bent from an end of the locking portion and extending outwardly for connection with a second PCB.
