Title: Deep water completions fracturing fluid compositions
Inventor: CREWS JAMES B
IPC: C09K8/68
Filed: 2002-11-12
Abstract: It has been discovered that fracturing fluid compositions can be designed for successful deep water completion fracturing fluid operations. These fluids must be pumped relatively long distances from offshore platforms to the reservoir, and they are often subjected to a wide temperature range. Under these conditions, it is necessary to inhibit the formation of gas hydrates in the fracturing fluid compositions, as well as to delay the crosslinking of the gels that are formed to increase the viscosity of the fluids prior to fracturing the formation. Preferably, two different gas hydrate inhibitors are used to ensure placement of a gas hydrate inhibitor in most parts of the operation. In addition, as with all offshore or deep water hydrocarbon recovery operations, it is important that the components of the fracturing fluid compositions be environmentally benign and/or biodegradable.

Abstract: Externally mounted downspouts normally discharge water adjacent to a building's foundation. The drain spout of the present fits onto such downspouts to redirect the water away from the building's foundation, and is constructed of a durable and resilient rubber to avoid permanent deformation and blockage of its internal channel, and thus avoid moisture or water backing up into the foundation of the building. The drain spout is preferrably square or rectangular in shape, is four to five feet (1.2 to 1.5 meters) long, and is constructed of a pliable rubber forming at least a 1/8 inch (3.2 mm) thick wall having smooth inner walls and external ribs. Such construction avoids breaking, squashing, flattening, bending, or other damage of the drain spout, and provides resistance to impact, abrasion and tearing.

Abstract: The invention generally relates to a method for fractionating plant material into valuable components including beta-glucan. The method uses an organic solvent and water instead of water alone, acidified water and/or aqueous alkali as a solvent for the slurrying of a grain flour. In addition to concentrating beta-glucan, other product fractions produced by the method include starch concentrate, and organic solvent solubles. If enzyme treatments are used, other product fractions include dextrin, protein hydrolysates and organic solvent solubles. The process is particularly effective in concentrating beta-glucans in a state close to its native form from the endosperm of barley and oat grains.

Abstract: This invention relates to a method for inhibiting a decrease in the transdermal flux of an agent that is being transdermally delivered or sampled over a prolonged period of time wherein the delivery or sampling involves disrupting at least the stratum corneum layer of the skin to form pathways through which the agent passes. The desired result is achieved by co-delivering or co-sampling the agent with an amount of at least one anti-healing agent wherein the amount of the anti-healing agent is effective in inhibiting a decrease in the agent transdermal flux compared to when the delivery or sampling of the agent is done under substantially identical conditions except in the absence of the anti-healing agent(s).

Title: Planar waveguide switch and optical cross-connect
Inventor: THACKARA JOHN I
IPC: G02B6/35
Filed: 2001-10-09
Abstract: A planar waveguide integrated optic switch (10)suitable for use in optical cross-connect applications. A narrow trench (13) in the planar waveguide core layer (12) is filled with a liquid crystal (14) material possessing positive birefringence. When held at a temperature a few degrees above the clearing point, the liquids crystal's isotropic refractive index is matched to that of the core layer allowing nearly complete optical transmission (17C) through the switch. When held at a temperature a few degrees below the clearing point, the liquid crystal's ordinary refractive index is lower than that of the core layer and both polarizations of the incident optical radiation are totally reflected (17b) from the trench. When coupled with planar waveguide beam expanding and refocusing elements, arrays of the switches can be used to form an optical cross-connect capable of fully interconnecting linear arrays of single- or multi-mode optical fibers with very low optical loss. By controlling the liquid crystal temperature at more than one location along the trench, the switch can be configured to operate as a variable attenuator.

Abstract: L'invention concerne un limiteur de débit non linaire restreignant la vitesse d'écoulement maximale dans un système d'aspiration médical. Le limiteur de débit modifie le sens d'écoulement d'un fluide, de manière à produire des effets non linéaires dans le fluide, créant ainsi une relation non linéaire entre la pression dans le système et la vitesse d'écoulement du fluide. La courbe non linéaire entre la pression et la vitesse d'écoulement présente une partie plate car la vitesse d'écoulement n'augmente pas lorsque la pression augmente.

Title: A controlled delivery system for hair care products
Inventor: SHEFER SHMUEL DAVID
IPC: A61K8/86
Filed: 2002-01-14
Abstract: The present invention is a controlled delivery system that can be incorporat ed in hair care products such as shampoos, conditioners, hair styling products, and other hair care products to effectively deliver a broad range of active agents and sensory markers, such as fragrances or cooling agents onto the hair. The system also prolongs the release rate of the active agents or sensory markers over an extended period of time, or provides heat triggered release of the active agents and yields a high impact fragrance "burst" upon blow drying the hair or other types of heat treatment. The controlled delive ry system of the present invention is a nano-particle, having an average partic le diameter of from about 0.01 microns to about 10 microns. The nano-particle comprises hydrophobic polymers and co-polymers, cationic charge boosters in conjunction with cationic surface-active conditioning agents that assist in adhering the particles onto hair. The invention further relates to a controlled delivery system where the release rate of the active ingredients is synchronized with that of a sensory marker to convey to the consumer the product performance.

IPC: A23L27/00
Filed: 2003-07-24
Abstract: Packaging materials and packages that transfer fragrances to foods and other products via the vapor phase are disclosed. The present invention provides a source of desired fragrance, a suitable environment for vapor transfer, and an appropriate food substrate to which flavor and fragrance is added. Examples of the source of fragrance can be a packaging film containing fragrance, a sachet of absorbed flavor material, a tape or label applied to the inside of a package, and a flavor diffusing granule or an active system for delivering flavor vapor to the environment. Materials that are preferably treated using the present invention include snacks, confections, baked goods, fresh plant materials, cereals and beverages, as well as non-food products. The time required for flavor transfer is dependent primarily on the volatility and concentration of the fragrances, absorptive capacity of the food, and the intensity of the flavor desired.
