Abstract: Un alliage fritté, résistant au fluage, ayant une disposition structurelle empilée d'un ou plusieurs métaux réfractaires Mo, W, Nb, Ta, V, Cr contenant certains agents de dopage, ainsi qu'un procédé permettant sa production. Les agents spéciaux de dopage sont des compositions et/ou des phases mélangées de ces compositions prises dans le groupe des oxides, des nitrures, des carbures, des borures, des silicates ou des aluminates ayant un point de fusion supérieur à 1500°C. La taille de leurs grains est 1,5 mum, leur proportion dans l'alliage est comprise entre 0,005 et 10 % du poids. A la différence des règles de l'art connues en ce qui concerne cet alliage, l'utilisation de potassium en tant qu'agent de dopage est evitée. Une bonne consolidation reproductible, et en particulier des densités élevées pendant le frittage, peuvent ainsi être obtenues. En outre, cet alliage a de meilleures propriétés de résistance à la température ambiante, à la chaleur et au fluage que les alliages de métaux réfractaires connus ayant une dispositions structurelle empilée.

Date Jul. 14, 1988.A device and a method for analyzing the elastic and/or viscous properties of gels or liquid is presented. The device has a member which moves reciprocally when driven by an electrical motor. A sensing member is provided which contacts the gel or liquid to analyze the properties of the gel or liquid. The sensor member is pivotably connected to the movable member through a connection, which on one hand puts the sensing member in motion upon movement of the movable member; but also allows relative movement of the sensing member and the movable member with respect to each other. A sensor apparatus is provided for delivering information pertaining to the resistance exerted by the gel or liquid on the sensing member upon movement of the movable member. A control unit, timer and switch are used to provide variable adjustment of the distance the electrical motor moves the movable member during the analysis process. The method is based upon movement of the sensing member to compress the gel or liquid between itself and a liquid movement delimiting wall.

Abstract: Compounds are disclosed for treating AIDS, herpes, and other viral infections by means of lipid derivatives of antiviral agents. The compounds consist of nucleoside analogues having antiviral activity which are linked, commonly through a phosphate group at the 5 min position of the pentose residue, to one of a selected group of lipids. The lipophilic nature of these compounds provide advantages over the use of the nucleoside analogue alone. It also makes it possible to incorporate them into the lamellar structure of liposomes, either alone or combined with similar molecules. In the form of liposomes, these antiviral agents are preferentially taken up by macrophages and monocytes, cells which have been found to harbor the target HIV virus. Additional site specificity may be incorporated into the liposomes with the addition of ligands, such as monoclonal antibodies or other peptides or proteins which bind to viral proteins. Effective nucleoside analogues are dideoxynucleosides, azidothymine (AZT), and acyclovir; lipid groups may be glycolipids, sphingolipids, phospholipids or fatty acids. The compounds persist, after intracellular hydrolysis, as phosphorylated or non-phosphorylated antiviral nucleosides. The compounds are effective in improving the efficacy of antiviral nucleoside analogues by prolonging the antiviral activity after the administration of the drug has ended, and in preventing retroviral replication in HIV infections which have become resistant to therapy with conventional forms of the antiretroviral agents.

Abstract: A subcutaneously implantable medication infusion device includes a variable capacity reservoir (22) for receiving and storing fluid medication for delivery to a cathether (26) which directs the medication to a specific infusion location in the body. A control assembly (28) is interposed between the reservoir (22) and the catheter (26) to facilitate and control the transfer of the medication from the reservoir (22) to the catheter (26) in a safe and efficient manner. The control assembly (28) includes a self-recharging pump (50) and a normally closed valve (52), both of which are manually actuable by percutaneous pressure when subcutaneously implanted, and defines a portion of a fluid flow conduit (24) between the reservoir (22) and the catheter (26). The control assembly (28) is constructed to permit the infusion of a measured bolus of medication on demand through manual percutaneous manipulation of the control assembly (28) to limit the rate at which the pump (50) is recharged with medication, to restrict the total amount of medication which can be pumped into the catheter (26) over a given period of time. In one preferred form, the pump recharge restriction is created by providing at least one capillary-like fluid pathway (110) through which the recharge fluid must pass before entering the pump (50). In another preferred form of the invention, the recharge flow rate of medication into the pump (50) is restricted by a wick restrictor (118). <IMAGE>   <IMAGE>

Dans le tube à cyclone (2), les  gaz d'échappement tournoient en spirale, avec une augmentation de la température d'environ 100°C, ce qui signifie pour des gaz qui affluent à une température d'environ 500°C une température finale d'environ 600°C. Cette température est suffisante pour brûler les particules de suie à l'intérieur du tube, de sorte qu'il n'en reste pratiquement plus dans les gaz d'échappement qui sortent de l'extrémité chaude.
