Abstract: Un dispositif et un procédé pour la mesure simultanée de la résistivité électrique et de la conductivité thermique de produits réfractaires, notamment carbonés. Le procédé consiste à chauffer une éprouvette cylindrique par passage d'un courant électrique croissant par paliers successifs, à attendre qu'un champ de températures stable soit établi dans l'éprouvette et à noter, à chaque palier, la tension électrique entre deux points symétriques par rapport au milieu de l'éprouvette, l'intensité électrique parcourant l'éprouvette et les températures en ces deux points symétriques et au milieu de l'éprouvette. Le traitement de ces données par ordinateur permet de déterminer la résistivité électrique et la conductivité thermique de l'éprouvette et leur évolution en fonction de la température. Le procédé s'applique à tous les produits réfractaires présentant une certaine conductivité électrique et thermique, carbures, nitrures et notamment aux produits carbonés.

Inventor: CLEGG MICHAEL W
IPC: F16L59/06
Filed: 1993-07-23
Abstract: An exhaust pipe assembly is provided for achieving a quick light-off of a catalytic converter.  Exhaust pipe assembly comprises circuitously bent inner and outer pipes disposed in generally concentric relationship to one another.  The inner pipe is formed from a very thin metal to provide a low thermal mass and a correspondingly low heat dissipation therefrom.  The outer pipe is thicker to provide structural support,  and defines an air insulation barrier around the inner pipe to further reduce heat dissipation.  The inner pipe is corrugated at selected locations that will correspond to bends  in the circuitous exhaust pipe assembly.  The thin-walled locally corrugated inner pipe is then inserted into the outer pipe, and the assembly is bent into the required configuration.   The corrugations support the inner and outer pipe relative to one another during the bending process and during use.   The bent pipe assembly then is connected to the catalytic converter for subsequent mounting to vehicle engine.

Inventor: MORITA KOICHI
IPC: C08F36/04
Filed: 1993-10-18
Abstract: A process for preparing a polymer comprises polymerizing a conjugated dime monomer and/or a vinylaromatic hydrocarbon monomer in a hydrocarbon solvent in the presence of or in the absence of a randomizer by using a lithium polymerization initiator which is formed by bringing an organolithium compound and at least one secondary amine compound into contact with each other in the polymerization system in the presence of at least said monomer. The secondary amine is an amine compound having two hydrocarbon groups bonded to N or an imine compound in which an NH group and a saturated or unsaturated cyclic structure group form a cyclic structure.      The cyclic structure group comprises a hydrocarbon group as the ring member and may also comprise N or O. The method of production uses the initiator which does not require separate preparation of the initiator, shows excellent reproducibility, allows for the evaluation of accuracy of concentration and realizes high effective initiator concentration. The high molecular weight polymer produced by the method has a narrow molecular weight distribution; is controllable; has a highly reproducible molecular weight and microstructure; exhibits excellent coupling properties based on the living polymerization and provides low hysteresis loss properties.

Title: Removable seats for a dual poppet valve
Inventor: MAALOUF JASON GHASSAN
IPC: F16K1/44
Filed: 1992-06-09
Abstract: In a valve having a housing with a cavity therein with an entrance port connected to a source of fluid and an outlet port connected to a fluid system. The valve has a body with first and second poppet members which control the flow of fluid from the entrance port to the outlet port. An actuation member connected to the body moves the first and second poppets with respect to first and second seats, respectively, to control the flow of fluid from the entrance port to the cavity and correspondingly the flow of fluid to the outlet port. The actuation member sequentially moves the first and second poppets toward the first and second seats, respectively, by initially moving the second poppet into engagement with the second face to partially interrupt the flow of fluid through cavity and thereafter moving the first poppet into engagement with the first face to completely interrupt the flow of fluid through the cavity to the outlet port. The first and second seats each have a cylindrical member located in said cavity with a first end having a flange and a conical surface thereon and a second end that engages the housing, the conical surface defining the contact for the seating of the corresponding first and second poppets on the body. A flexible member located in grooves in the housing engages the cylindrical members of the first and second seats and a locking ring attached to the housing retains the cylindrical members in the housing while compressing the flexible member to form seals between the cylindrical members and the housing. The flexible member allows some dimensional changes to occur in the housing without effecting the sealing to assure that the flow of fluid through the cavity to the outlet port is interrupted when the first and second poppets engage said first and second seats.

Title: Method and apparatus for performing and universally detecting capillary isoelectric focusing without mobilization using concentration gradient imaging systems
Inventor: PAWLISZYN JANUSZ B
IPC: B01D57/02
Filed: 1993-01-13
Abstract: The separations resulting from capillary electrophoresis performed in a microbore capillary tube (35) are detected on-line by focusing a light beam (63) in the form of a line or sheet of light (63) on the capillary passage (36) in which the separations (55a-c) take place so that the width of the sheet of light encompasses the length of the passage in which separations of interest are expelled to take plan. The separations form concentration gradients (16) in the capillary passage (36) encompassed by the light beam and cause refraction of portions of the light beam and variations in the intensity of the light beam due to such refraction. Alternately, the separated components (55a-d) may absorb light of certain frequencies so if the light beam includes light of the certain frequencies, variation in the intensity of the light beam is caused by such absorbance. The variation in the intensity of light along the width of the light beam after passage through the sample (125) is sensed and is indicative of the concentration gradients (160, 161). By using a reagent (125) which reacts with an analyte not having an isoelectric point to form a product having an isoelectric point (100, 101), such analyze may be detected and measured by isoelectric focusing techniques.
