    Abstract: A novel process and apparatus is disclosed for performing chemical reactions. Highly compressed gaseous streams such as H2, CO, CO2, H2O, O2, or CH4 are raised to Mach speeds to form supersonic jets incorporating shockwaves. Two or more such jets are physically collided together to form a localized reaction zone where the energy from the shockwaves causes endothermic reactions wherein the chemical bonds of the reactant gases are broken. Between and among reactants molecular surface interaction and molecular surface chemistry take place. In the ensuing exothermic reactions a desired new chemical product is formed and this product is locked into a lower state of enthalpy (state of energy of formation) through adiabatic cooling by means of a free jet expansion.

  • Publication number: 20120213969
    Abstract: A functionally graded shape memory polymer (SMP) that has a range of transition temperatures that are spatially distributed in a gradient fashion within one single article. The SMP is formed by post-curing a pre-cured glassy SMP in a linear temperature gradient that imposes different vitrification temperature limits at different positions along the gradient. Utilizing indentation-based surface shape memory coupled with optical measurements of photoelastic response, the capability of this material to respond over a wide range of thermal triggers is correlated with the graded glass transition behavior. This new class of SMP offers great potential for such applications as passive temperature sensing and precise control of shape evolution during a thermally triggered shape recovery.

  • Patent number: 8148465
    Abstract: The invention relates to a process for free-radically initiated heterophase polymerization, in which the polymerization of ethylenically monomers proceeds in a phase dispersed in the continuous phase, characterized in that one or more additives which are soluble in the continuous phase and insoluble in the disperse phase and stop the polymerization of the ethylenically unsaturated monomers in the continuous phase is/are added before or during the polymerization.

  • Patent number: 8119745
    Abstract: Process for the manufacture of 1,2-dichloroethane (DCE) starting from a stream of ethane which is subjected to a catalytic oxydehydrogenation (ODH) producing a gas mixture containing ethylene then dried and subjected to an absorption to be separated into a fraction enriched with the compounds that are lighter than ethylene containing some of the ethylene conveyed to a chlorination reactor R1 in which most of the ethylene is converted into DCE, and into a fraction F1 which is subjected to a desorption D1 to be separated into an ethylene fraction depleted of the compounds that are lighter than ethylene conveyed to a chlorination reactor R2, the stream of products derived from this reactor being added to the dry gas mixture, and into a fraction F2. Fraction F2 is then subjected to a desorption D2 to be separated into a fraction enriched with ethylene conveyed to an oxychlorination reactor in which most of the ethylene is converted into DCE, and into a fraction F3 which is recycled to the absorption.

  • Patent number: 8058378
    Abstract: An extrudable polyvinyl chloride composition comprising from 80 to 99.9 percent by weight polyvinyl chloride for use in extruding a first part and a second part, wherein a fusion joint between the first extruded part and the second extruded part is formed by: A) composition at least a portion of a first terminal edge of the first extruded part and a first terminal edge of the second extruded part; B) engaging the melted terminal edges; and C) maintaining pressure between the engaged terminal edges to create a fused joint having a strength that is at least 50% of the tensile strength of the extruded part as measured by ASTM D638-2a. The extruded parts can be pipe sections.

  • Publication number: 20110265797
    Abstract: The present disclosure describes systems and methods that utilize an extendable tracheal tube system. The extendable tracheal tube system includes an extendable tracheal tube having a distal end portion and a proximal end portion. The proximal end portion and the distal end portion of the extendable tracheal tube are capable of moving axially relative to each other. An obturator is also provided that is capable of aiding in the intubation and/or extubation of the extendable tracheal tube. The use of the extendable tracheal tube system and methods enables the secure attachment of the extendable tracheal tube to a patient airway while allowing for certain movements of the patient, such as neck and head movements.

  • Patent number: 8049047
    Abstract: Process for the manufacture of 1,2-dichloroethane (DCE) starting with a hydrocarbon source which is subjected to a cracking thus producing a mixture of cracking products then subjected to treatment steps to obtain a mixture of products containing ethylene. The mixture is afterwards subjected to a first separation step into a fraction enriched with the compounds that are lighter than ethylene containing some of the ethylene conveyed to a chlorination reactor in which most of the ethylene is converted to DCE, and into a fraction F1 which is subjected to a second separation step into a fraction F2 and into a heavy fraction. Fraction F2 is afterwards subjected to a third separation step into a fraction enriched with ethylene conveyed to an oxychlorination reactor in which most of the ethylene is converted to DCE, and into a fraction F3 mainly composed of ethane.

  • Publication number: 20110168657
    Abstract: The present invention describes plastic materials and food additives that are free or substantially free from endocrine disruptive chemicals. The plastic materials may be used in products which are exposed to individuals in which endocrine disruptive activity is particularly disadvantageous, such as baby bottles, baby toys, food containers, medical containers, animal cages and medical products. The food additives may be used in food products that are ingested by individuals in which endocrine disruptive activity is particularly disadvantageous, such as newborns or the physically infirm. The present invention also describes a series of assays which, when performed in combination, provide a novel method for determining the presence of endocrine disruptive activity.
