  • Publication number: 20160157681
    Abstract: A floor support structure for a bathtub or a shower tray floor, taking the form of a separate element to be used in conjunction with a traditional bathtub or shower tray floor, or as a unitary shower tray floor formed with the support structure integrated therein. The supports include a hollow plastic shell having a lower surface for lying on a planar subfloor, an upper surface contoured to the desired shape and a peripheral sidewall extending there between. Preferably, a drain hole is formed in the plastic shell which also interconnects the upper and lower surfaces thereby defining a hollow interior cavity. The cavity is filled with expandable thermoplastic foam beads which are expanded in place with steam in order to substantially fill the interior cavity thermally bonding the beads together and to the shell interior wall. The expanded foam bead is capable of being compressed without substantial permanent set.

  • Publication number: 20150336349
    Abstract: An elongated structural article, having a continuous profile extrusion with spaced apart layers defining a portion of a cavity filed filled with thermoplastic pre-expanded beads expanded with steam in-situ causing the beads to securely bond together and to the profile extrusion. The article is cut to a length forming ends having an exposed foam core. A system for manufacturing the article is also disclosed having a profile extrusion die for forming an axially profile defining a wall surrounding a cavity, a tubular shaping mold located axially downstream of the extrusion die sized to support a length of the profile as it passes there through. A bead dispenser is oriented to introducing pre-expanded beads into the profile cavity while within the shaping fixture and a steam tube is oriented downstream of the introduction of pre-expanded beads. Control valves regulate the flow of pre-expanded beads and steam into the profile cavity.

  • Patent number: 9102086
    Abstract: A method of manufacturing an elongated article is recited to include extruding a first and a second layer each having peripheries. The second layer is spaced apart from and opposed to the first layer. Together, they define a cavity between them. Into that cavity particles are dispensed. The particles are expanded with an expansion fluid to form an in-situ foam core and to thermally bond the in-situ foam core to the first and second layers. The first and second layers having the thermal bond to the in-situ foam core are shaped to form the article. An elongated article from this process is also recited.

  • Publication number: 20150050211
    Abstract: Provided herein are methods to generate and screen peptides that exhibit drug like stabilities in vitro and in vivo. By selecting for enzyme resistance, Applicants are able to derive peptides that are not only stable to a broad spectrum of proteases, but also stable to other drug processing enzymes such as cytochrome P450s. This approach provides a general method to the rapid development of highly stable peptides for therapeutic development and diagnosis. The peptides are further modified for oral bioavailability.
