Abstract: La présente concerne un appareil de formation de vide pour positionner une ancre dans une structure en béton, qui comprend un corps creux polymère ayant des première et seconde sections articulées par charnières entre elles pour permettre un mouvement entre une condition fermée en prise autour de l'ancre reçue entre celles-ci et un état ouvert dans lequel les sections sont séparées dans leurs parties inférieures pour libérer l'ancre reçue entre elles. L'appareil de formation de vide est formé de façon monolithique par moulage par injection et comprend des éléments de verrouillage formés intégralement sur les sections respectives pour leur engagement mutuel afin de maintenir les sections dans l'état fermé et un pont entre les sections pour assurer une connexion articulée entre elles. Dans le procédé de moulage par injection, les sections sont formées de manière à être positionnées dans l'état ouvert. Lors de leur retrait du moule d'injection, les sections sont articulées l'une par rapport à l'autre par flexion du pont entre elles, avant que le polymère n'ait entièrement durci. Cette flexion aligne les molécules de la matière polymère à l'intérieur du pont pour permettre au pont de servir de charnière et permettre une flexion répétée.

Title: Process for producing edible quality refined fish oil
Inventor: CROWTHER JANE BRUCE
IPC: C11B1/06
Filed: 2000-12-01
Granted: 2010-02-09
Abstract: A method for producing edible quality refined fish oil comprising the steps of extracting press liquor from a cooked fish, wherein the press liquor consists primarily of fish oil and water inherent in the cooked fish. The fish oil is from the group of fish consisting of menhaden, other similar fish, and mixtures thereof. Enzymes present in the press liquor are deactivated by injecting an acidic solution into said press liquor. After the fish oil is removed from the press liquor, the fish oil is cold filtered to produce an olein fraction and a stearine fraction. The stearine fraction is separated from the olein fraction and fatty acids that remain in the olein fraction are removed. Then bleaching the fish oil by mixing amorphous silica and diatomaceous earth with the fish oil, under vacuum conditions, and deodorizing the fish oil under vacuum conditions with steam injection. Finally, preparing the fish oil for storage by mixing a chelating agent and antioxidants with fish oil. Also disclosed is a refined fish oil that is free of unsavory taste or smell, have an anisidine number of less than 6, and retain more than 98% of the omega-3 long chain fatty acids present in the natural unrefined fish oil.

Title: Process for producing synthesis gas by non-catalytic partial oxidation of natural gas
Inventor: EIKANI MOHAMMAD H
IPC: B01F23/10
Filed: 2003-05-08
Granted: 2008-09-23
Abstract: A process and apparatus is described for continuously producing synthesis gas by a unique non-catalytic partial oxidation reaction. The gaseous reactants, typically natural gas as fuel and oxygen as oxidant are separately preheated by electrical heaters prior to mixing upon discharge from a swirling jet burner into a partial oxidation reactor. The resulting effluent gas stream is subsequently cooled in a quench chamber to produce a product gas. The flow rates of the natural gas and oxidant are adjusted in order to maintain a fuel equivalence ratio between about 2 to about 4. As a result the H2/CO ratio, CO selectivity, natural gas conversion and synthesis gas yield are obtained in a ratio of 0.6 to 1.0, 80 to 90%, 60 to 80% and 1.2 to 1.6, respectively. The resulting product gas may be used as synthesis gas, reducing gas, or fuel gas.

Abstract: The invention relates to thermoplastic compositions comprising a thermoplastic polyamide matrix and at least one additive which modifies the interaction between the matrix and an agent.  The purpose of the invention is to provide an additive which modifies the interaction between a copolyamide-type thermoplastic copolyamide matrix and at least one agent.

Moreover, said additive can be used for the controlled modification of the interaction between the thermoplastic copolyamide and an internal or external chemical agent.  Preferably, the composition does not contain hyperbranched polymers which produce therein a reduction in the molar mass of matrix M which is greater than or equal to 7 % in relation to a sample composition which comprises matrix M but does not contain hyperbranched polymer additive(s).  Said mass measurement is taken preferably using a determined protocol P.  The invention is suitable for use in moulding, injection moulding, injection/blow moulding, extrusion/blow moulding, extrusion or spinning.

Abstract: L'invention concerne un dispositif, un procédé et un programme pour la présentation de médias ad hoc. On utilise des dispositifs portatifs améliorés en combinaison avec les autres unités pour l'acheminement des médias et le contrôle de la présentation des médias. Des postes de présentation des médias améliorés détectent la présence d'un ou plusieurs dispositifs portatifs. Ensuite, l'information relative à la présence d'un dispositif portatif est transmise par ces postes à un serveur amélioré. Le serveur utilise l'information pour établir un enregistrement de l'emplacement de chaque dispositif portatif. L'information d'emplacement enregistrée permet d'acheminer les médias vers le poste de présentation le plus proche de l'emplacement du dispositif portatif. L'information de contrôle, du type sélection des médias et contrôle de fidélité (selon le cas), est transmise depuis le dispositif portatif vers le serveur, pour que le serveur puisse prendre des dispositions appropriées concernant l'acheminement des médias vers le poste de présentation concerné. En cas de réception d'appel téléphonique, un téléphone amélioré correspond avec le serveur pour interrompre la présentation des médias jusqu'à la fin de l'appel.
