Publication number: 20080104911Abstract: A concrete wall forming system of mold units that include first and second panel members and a plurality of connecting members. The panel members each have a horizontal length of three to thirty feet and a vertical height of three to twenty feet. The inner sides of the panels include slots extending vertically therethrough. The connecting members are detachable and securable with respect to the panels and extend the length vertically therebetween to maintain a spatial distance for defining a molding chamber. The connecting members include flanges detachably and securably extending within the slots in the panels. A mid-section portion in the connecting members contains a plurality of pour holes spaced along its length vertically. Concrete can be poured into the molding chamber and through the pour holes and once allowed to set and harden forms an insulated concrete wall.Type: ApplicationFiled: November 8, 2006Publication date: May 8, 2008Inventors: Shawn P. Jarvie, Michael T. Williams, Justin D. Rubb, Ginawati Au, John K. Madish, Blain Hileman

Patent number: 7252866Abstract: A foam thermoplastic container e.g. cup, bowl molded from expandable thermoplastic particles e.g. expandable polystyrene, has a film made of a thermoplastic resin e.g. solid polystyrene, rubber-modified polystyrene, PET, polyethylene, polypropylene, fused to its inner sidewall surface by heat and pressure to create a barrier to resist the leakage of liquid and food with oil and/or fatty components and to increase the rim strength of the container. The thermoplastic resin film can be fused to the outer surface of the container for printing purposes and/or to create a barrier and/or can be fused to the base surfaces of the container. The molding machine used to form the foam container is used to fuse the film to the container.Type: GrantFiled: December 20, 2002Date of Patent: August 7, 2007Assignee: NOVA Chemicals Inc.Inventors: Jiansheng Tang, Jeffory E.

Publication number: 20070148386Abstract: A method for improving the resistance of fumigant sorption in a produce container made of expandable polystyrene particles in a fumigation process, and related produce container. Expandable polystyrene particles having a density ranging from 40.0 to 32.0 pounds per cubic foot and a blowing agent amount ranging from 2.5 to 7.5 weight percent are pre-expanded to form pre-expanded particles having a core bulk density ranging from 12.5 to 2.0 pounds per cubic foot, and a skin density ranging between 40.0 and 32.0 pounds per cubic foot and a thickness ranging from 0.1 to 2 microns. These pre-expanded particles are injected into a mold to form a produce container having a wall thickness ranging from 0.25 to 2.0 inches.Type: ApplicationFiled: December 4, 2006Publication date: June 28, 2007Inventors: Jiansheng Tang, Michael T.

Patent number: 4839104Abstract: A novel three-step process for preparing 4-(3,4-dichlorophenyl)-4-phenylbutanoic acid is disclosed, which involves (1) reducing 4-(3,4-dichlorophenyl)-4-ketobutanoic acid to 4-(3,4-dichlorophenyl)-4-hydroxybutanoic acid; (2) then converting the intermediate hydroxy acid formed in the first step to 5-(3,4-dichlorophenyl)-dihydro-2(3H)-furanone, and (3) thereafter reacting the resulting gamma-butyrolactone compound with benzene in a Friedel-Crafts type reaction to form the desired final product. The latter compound is known to be useful as an intermediate leading to 4-(3,4-dichlorophenyl)-3,4-dihydro-1(2H)-naphthalenone and ultimately, to cis-(1S)(4S)-N-methyl-4-(3,4-dichlorophenyl)-1,2,3,4-tetrahydro-1-naphthal ene amine (sertraline), which is known to be a preferred anti-depressant agent in the field of medicinal chemistry. The aforementioned 5-(3,4-dichlorophenyl)-dihydro-2(3H)-furanone and 4-(3,4-dichlorophenyl)-4-hydroxybutanoic acid are both novel compounds.Type: GrantFiled: June 16, 1988Date of Patent: June 13, 1989Assignee: Pfizer, Inc.Inventors: George J.
