Publication number: 20060263406Abstract: An implantable infection shield and system for drug delivery in vascular tissue includes a relatively non-biodegradable porous linked fibrous biomaterial which controls and directs cell growth and angiogenesis from adjacent vascular tissue into the implant. Infection shield embodiments stimulate cell growth and angiogenesis from adjacent vascular tissue which effectively blocks passage of pathogenic microorganisms along percutaneously implanted objects. In embodiments for drug delivery, a reservoir of the same biomaterial may contain either (1) a cell culture system enclosed within a porous sealable interior chamber or (2) a biodegradable matrix in which one or more drugs are dispersed. After implantation of a reservoir of the first embodiment in an organism, cultured cells obtain food and oxygen via diffusion in tissue fluid through the porous walls of the interior chamber, while metabolic products, including drugs, diffuse away from the cell culture in an analogous manner.Type: ApplicationFiled: May 1, 2006Publication date: November 23, 2006Inventors: Mark Lyles, Charles McLaughlin, Glenn Halff, William Mallow

Patent number: 6677159Abstract: An apparatus and method for visually and continuously monitoring gaseous concentrations of electrophiles such as carbon dioxide. A coating composition comprising an organic binder, filler/pigment, an activator, and carbon dioxide sensitive color indicator interacts with a primed substrate to which it is applied for support.

Patent number: 6524543Abstract: Disclosed is a commercial grade of soluble silicate solutions, clear homogenous and water white essentially free of unreacted silica, made by dissolving in a closed container biogenic silica, preferably rice hull ash, in a strong alkali solution, preferably sodium hydroxide in the presence of an agent, such as an active carbonaceous material, which prevents discoloration of the soluble silicates by absorbing and/or reacting with polyvalent metals, organic materials, and the like, in the biogenic silica as it dissolves in and reacts with the alkali solution. The invention takes advantage of the residue of such active carbonaceous material on the biogenic silica, such as rice hulls, left by commercial energy burning thereof which effectively prevents discoloration. A solid residue results from the method which is an active carbonaceous material including concentrated manganese from the biogenic silica, both of which are valuable commercial products.Type: GrantFiled: August 25, 1998Date of Patent: February 25, 2003Inventors: Roy S.

Patent number: 6283228Abstract: A method for protecting integrity of a core sample during transport from a subterranean formation to the surface comprising: cutting a core sample from the subterranean formation using a drilling fluid; encapsulating the core sample with an encapsulating material that is separate from the drilling fluid and comprises a property which renders the encapsulating material capable of protecting the chemical integrity of the core sample during transport from the subterranean formation to the surface, wherein the property is other than a property selected from the group consisting of a viscosity which increases in response to a decrease in temperature and an ability to solidify in response to a decrease in temperature; and, transporting the encapsulated core sample from the subterranean formation to the surface.Type: GrantFiled: December 15, 2000Date of Patent: September 4, 2001Assignee: Baker Hughes IncorporatedInventors: Pierre Emmanuel Collee, Steven R.

Patent number: 6241711Abstract: A face masque that applies cooling therapy to facial features of a patient. The masque is formed of two nylon or plastic layers that define a closed interior space and filled with a cooling medium that includes water, glycerin and hydroxyethyl cellulose. The masque controls the rate of heat dissipation from a user based upon the heat capacity, mass, rheology and composition of the materials used. The masque is lighter than conventional water-filled ice packs. It remains unfrozen and malleable even when cooled to sub-zero temperatures at which water-filled packs would freeze solid. The masque readily conforms to facial features due to the materials used, thereby contributing to improved comfort on the part of a user. Further, the masque possesses improved cooling therapy because it remains cold for longer periods of time relative to water-filled ice packs. Optionally, the masque accommodates eye inserts placed between a main body of the masque and recesses of the patient's eyes.Type: GrantFiled: January 28, 1998Date of Patent: June 5, 2001Assignee: SkinVestment, LLCInventors: Gloria Weissberg, Tina Alster, Felix Franks, William Mallow

Patent number: 6231650Abstract: The present invention prolongs the biocidal activity of hydrated lime in a paint or coating by using a sufficient amount of a binder in the paint or coating to block carbon dioxide from reacting with the hydrated lime while still producing a coating that is durable and adhesive upon drying and not unduly friable due to the amount of hydrated lime in said coating.Type: GrantFiled: September 17, 1999Date of Patent: May 15, 2001Assignee: Alistagen CorporationInventors: William A.
