    Abstract: A wheel chock has a body with a shell and filled core construction capable of supporting high chocking loads while being relatively lightweight and portable. The chock includes walls sized and shaped to support large-diameter wheels such as wheels of large haul vehicles and mining trucks. The chock can be sized proportional to the radius of the wheel to be retained or based on the radius of curvature of a wall configured to primarily support the outer surface of the wheel. The chock can have a cut off or flattened toe or front surface that reduces weight and helps to ensure that the entire chock is load-bearing when in a chocking position. The chock can also have a flattened top surface to support the outer surface of a tire that deforms around the chock while it is being retained by the chock.

  • Patent number: 9040598
    Abstract: A thermoplastic composition that contains a rigid renewable polyester and has a voided structure and low density is provided. To achieve such a structure, the renewable polyester is blended with a polymeric toughening additive to form a precursor material in which the toughening additive can be dispersed as discrete physical domains within a continuous matrix of the renewable polyester. The precursor material is thereafter stretched or drawn at a temperature below the glass transition temperature of the polyester (i.e., “cold drawn”). This creates a network of voids located adjacent to the discrete domains, which as a result of their proximal location, can form a bridge between the boundaries of the voids and act as internal structural “hinges” that help stabilize the network and increase its ability to dissipate energy. The present inventors have also discovered that the voids can be distributed in a substantially homogeneous fashion throughout the composition.

  • Patent number: 8901180
    Abstract: The invention relates to a method for functionalizing a thermoset, crosslinked isocyanate-based polymeric solid material which is made of isocyanate and isocyanate reactive components, at least one of which comprises an anchor component which has at least one anchor group. The anchor groups on the solid material are formed by terminal alkene and/or alkyne groups. To functionalize this polymeric solid material it is brought in contact with a solution which contains at least one functional component. This functional component comprises at least one thiol group and is allowed to bind covalently to the polymeric solid material by a free-radical addition reaction between the thiol groups on the functional component and the terminal alkene and/or alkyne anchor groups on the undissolved solid material. An effective functionalization of the polymeric material can thus be achieved notwithstanding the heterogeneous reaction conditions.

  • Patent number: 8871823
    Abstract: A first polymer (preferably in granular form) is exposed to a gas at a pressure higher than atmospheric pressure to introduce the gas into the polymer. This occurs at a temperature from the glass transition temperature to the melting temperature when the first polymer is crystalline or semi-crystalline in nature, or at a temperature below the glass transition temperature when the first polymer is amorphous in nature. Optionally, the gas-laden polymer may then be mixed with a second polymer. The polymer is then melted to produce a foamed article.

    Abstract: A prepreg composite that contains a porous substrate impregnated with an aromatic polyester is provided. In addition to possessing a high degree of heat and moisture resistance, the present inventors have also discovered that the nature of the aromatic polyester can be selectively controlled so that it is soluble in a solvent. This allows for the formation of polymer solutions that can be readily employed to impregnate the porous substrate. The nature of the polyester and its relative concentration in the solution can also be tailored to achieve polymers that not only adhere well to the substrate, but also possess good thermal and mechanical properties for use in a wide variety of potential applications.
