Abstract: Structural analogues of fibroblast growth factors have an amino acid sequence replacement in the ninth or tenth beta strand of the factor, or the sequence that corresponds to the surface loop that connects the ninth and tenth beta strands, such that the folding of the molecule is not significantly perturbed.  Preferred analogues have the overall secondary and tertiary structure of the original factor, and bind to heparin and a member or members of the fibroblast growth factor receptor family with high affinity.  In some embodiments  the replacement is with another amino acid sequence such as a loop sequence from another  structurally related fibroblast growth factor or an interleukin.  The figure discloses amino acid sequences from FGF-1, FGF-2, and IL-1 beta.

Abstract: A method for making a transdermal drug delivery device for heat sensitive and volatile drugs is disclosed. The device contains a drug-containing adhesive composite layer having an impermeable backing material laminated to the distal surface thereof and a proximal peelable impermeable backing material adapted for removal for administering a drag to the skin or mucosa laminated to the proximal surface thereof. The figure provides a partly schematic, sectional view of the transdermal drug delivery device (10) including the substantially drug-impermeable distal backing (14), a drug laden adhesive composite (18) and a substantially drug impermeable proximal release liner (22). The adhesive composite (18) is comprised of a distal adhesive layer (19), a proximal adhesive layer (20) and a gelled drag layer (21) disposed therebetween. The device is produced by extruding the drag in gel form onto at least one exposed surface of a first or second adhesive laminate such that the adhesive layers and gelled drug are combined to form the drug-containing adhesive composite layer having the distal and proximal surfaces covered by the respective backing materials.  This process is particularly adaptable to the formulation of nicotine-containing patches.

Abstract: L'invention porte sur un procédé de régulation de la taille de particules d'additif ou de catalyseur mélangées à des apports d'huiles hydrocarbures qui contiennent des asphaltènes et des métaux et sont soumis à un hydrotraitement. Un apport de boues fait d'un mélange d'huiles hydrocarbures et de particules d'additif inhibiteur de coke ou de particules de catalyseur est entraîné de bas en haut dans une zone verticale confinée d'hydrotraitement, en présence d'hydrogène, tandis qu'on extrait du sommet de la zone d'hydrotraitement un effluent mixte constitué d'une phase gazeuse d'hydrogène et de vapeurs d'hydrocarbures, et d'une phase liquide contenant des hydrocarbures lourds. L'effluent mixte passe dans une cuve de séparation tandis qu'on extrait du sommet du séparateur un courant gazeux d'hydrogène et de vapeurs d'hydrocarbures, et, de la base du séparateur, un courant liquide contenant des hydrocarbures lourds et des particules d'additif inhibiteur de coke et de catalyseur. Une partie au moins du courant liquide contenant des hydrocarbures et des particules est recyclée et une huile aromatique est ajoutée à la zone d'hydrotraitement en quantité suffisante pour empêcher pratiquement l'adsorption des asphaltènes à la surface des particules et l'agglutination résultante des particules d'additif et de catalyseur.

Abstract: Colle à onduler produite en continu selon les nécessités, en utilisant une chambre de mélange contenant un agitateur et une chambre de contrôle comportant un dispositif mesurant la viscosité. Chaque ingrédient de la colle est ajouté en proportion requise dans la chambre de mélange à un débit volumétrique correspondant sensiblement à la vitesse d'utilisation de la colle dans une machine à carton ondulé. Une portion de pâte d'amidon brute est déversée de manière régulable pour être mélangée avec un agent de base permettant d'adapter la viscosité d'adhésion, la quantité non mélangée étant ajoutée à la chambre de mélange. Ainsi la quantité de colle produite est équilibrée avec la quantité utilisée et permet d'apporter de la colle fraîche tout au long d'un processus d'ondulation sans qu'une réserve importante de colle ne soit nécessaire, ce qui permet de réduire les frais d'investissement et les pertes de colle.

Title: Central vacuum hose dispenser
Inventor: GOSSELIN TILMON JOSEPH PAUL
IPC: A47L9/24
Filed: 1999-02-22
Granted: 2008-03-25
Abstract: In a first aspect of the invention, there is provided an apparatus for storing and dispensing a vacuum hose of a central vacuum system. The apparatus comprises a base frame, a basket pivotally mounted on a thrust bearing affixed to the base frame, and a conduit rigidly held above the basket relative to the base frame and extending along the pivotal axis of the basket. When a vacuum hose is inserted downward inside the conduit and into the basket, the weight and resiliency of the hose causes the basket to rotate for coiling the hose therein without twisting it. The hose is thereby neatly stowable between uses. In another aspect, the base frame and the basket are installed beneath the floor of a house and the conduit extends upwardly into a wall cabinet above the main floor of the house and near a vacuum inlet socket of the central vacuum system.

Filed: 1997-10-08
Granted: 2006-07-11
Abstract: A shock-absorbing telescoping tool handle (2) is disclosed having tubular, larger diameter proximal and a smaller diameter distal portions (4, 6). An internal spring (14) between the handle portions is compressed when the handle portions telescope toward each other. Guide mechanism (26, 28) in the handle portions limits the extent of sliding motion between the handle portions and prevents relative rotation of the handle portions. One or more wipers (40) in the handle portions wipes away any snow, water or debris on the distal portion which could potentially enter the spring area.
