Abstract: A chemical injection unit consisting of one or more injection loops that uses a Venturi injector and motorized valve with a control system to isolate chemicals from water until operating conditions are suitable to carry the chemical and water mixture down the main flow pipe. The invention adjusts chemical injection rate to maintain desirable operational properties, including chemical injection rate, chemical concentration, or fluid viscosity. Accurate and real-time injection of chemicals is beneficial for safety as well as economics of the drilling operation in terms of reduced drilling time, efficient use of chemicals, and minimal variation in processing conditions.

Abstract: A nasal respiratory delivery device includes fabric pads or fabric domes that cover the nostrils and includes a plastic strip with skin-sensitive adhesive for attachment of the device to the septum and the outside of each nostril, and provides for suppressing the human cough via moistening and warming inhaled air, thus soothing the respiratory passageways and mitigating the cough reflex. The nasal respiratory delivery device also provides for cough suppressants, nasal decongestants or other medical or breathing treatments. The nasal respiratory delivery device is placed across both nasal openings and adhered to the nasal septum and to the tissue surrounding the nostrils. The fabric pads or fabric domes are composed of nonwoven or woven manmade and/or natural materials that absorb and provide moisture or therapeutic agents during the act of breathing.

Abstract: The described “Foldable Food Grade Cooking Surface and Method of Use” provides cooks of average skill the means to cook soft and fragile items, such as eggs, omelets, crepes, etc., without breaking such items while cooking. The Foldable Food Grade Cooking Surface is made of flexible, thermally conductive, mechanically stable, food grade material such as silicone with or without reinforcing fillers. The preferred embodiment includes handles for manipulating fragile food items during cooking and serving, without the need for traditional cooking implements. Non-planar surface topology, such as ridges, on the cooking surface of the Foldable Food Grade Cooking Surface contain cooking foods within predefined areas, such as the perimeter, of the cooking surface, and can act as a mold for foods that begin in a state that can flow (e.g. liquids of varying viscosity).

Abstract: The present invention relates to a package that includes an enclosure having a first substance and a second substance within the enclosure. The package further includes a plastic zipper which segregates the first substance from the second substance within the enclosure such that opening the plastic zipper allows the first substance and the second substance to be mixed together inside the enclosure. In another aspect, the package includes a gas-permeable enclosure and first and second solid substances stored within the enclosure. A mechanism, such as a plastic zipper, segregates the first and second solid substances. Opening the mechanism allows a user to mix the first and second solid substances inside the enclosure to produce a gas. The package permits the gas that is produced to permeate through the gas-permeable enclosure for distribution throughout an area.

Abstract: The present invention provides a substrate treated with an linked enzyme. It has been discovered that a substrate treated with a linked enzyme can be effective in improving the ability of the substrate to absorb viscoelastic materials, such as menses, by cleaving a protein structure present in some viscoelastic materials. In addition, the linked enzyme is less likely to migrate from the treated material onto the user, as compare to an enzyme being placed directly on the substrate, thereby reducing the risk of sensitization to the user of the absorbent product. Also provided by the present invention are absorbent articles which contain at least one surface or layer containing the linked enzyme.

Abstract: The system and method of the present invention relate to characterizing lipoproteins in a sample. The system includes a light source that delivers electromagnetic energy in a predetermined range of wavelengths to the sample and a sensor that senses an intensity spectrum which emerges from the sample when the sample is illuminated by the light source. A processor characterizes lipoproteins that are within in the sample by deconvoluting the intensity spectrum into a scattering spectrum and absorption spectrum. The method includes illuminating the sample with electromagnetic energy having a predetermined range of wavelengths and sensing the electromagnetic energy that emerges from the sample. The method further includes transducing the sensed electromagnetic energy which emerges from the sample into an intensity spectrum that determines the types of lipoproteins that are within the sample.
