Abstract: A metered dosage inhaler system with variable positive pressure settings has a hollow housing with a front portion with a cylindrical protruding user adaptor portion, a top face having apertures, a user controlled air resistance dial, a bottom face having a handle/input, and a cylindrical downwardly extending hollow handle portion. The first end of the handle portion is adapted to form an airtight removable coupling with the handle/input adaptor. An end piece with holes is adapted to couple to the second end of the handle portion. A spherical ball has a diameter less than that of the handle portion and removably rests in the handle portion. The ball rises in response to a vacuum caused by a,patient. A mouth piece portion has a cylindrical first portion removably coupled to the adapter portion and a tapered second portion adapted to fit comfortably within the mouth of a patient.

Abstract: An oxygen connector system for coupling an oxygen source to an oxygen tube comprises a source of oxygen. The source has an output orifice through which source oxygen is adapted to pass. The orifice has an inner bore and an outer surface. A flexible cylindrical elastomeric tube has a first input end and a second output end. The first input end is adapted to make a flush abutment with the source at the orifice. A generally cylindrical rigid connector has an exterior surface with a first region and a second region. An intermediate tapered region is provided between the first and second regions. The connector has a central generally cylindrical bore extending through the first and second ends forming an interior surface. The second end has a diameter slightly greater than that of the tube. A pair of stoppers are provided adjacent to the input end of the tube.

Abstract: A bioadhesive extruded single or multi-layered thin film, especially useful in intra-oral controlled-releasing delivery, having a water soluble or swellable polymer matrix bioadhesive layer which can adhere to a wet mucous surface and which bioadhesive layer consists essentially of 40-95% by weight of a hydroxypropyl cellulose, 5-60% of a homopolymer of ethylene oxide, 0-10% of a water-insoluble polymer such as ethyl cellulose, propyl cellulose, polyethylene and polypropylene, and 2-10% of a plasticizer, said film having incorporated therein a medicament, e.g., anesthetics, analgesics, anticaries agents, anti-inflammatories, antihistamines, antibiotics, antibacterials, fungistats, etc.

Abstract: An apparatus for transporting and preserving perishable test samples, comprising: a pair of substantially flat leaf members foldably connected to one another; membranes disposed on each of the leaf members over a substantial portion thereof, forming reservoirs; a latent refrigerant disposed in the reservoir; and, at least one strip for gripping and holding the leaf members together to surround and cushion the test sample, and hold the test sample in heat exchanging relationship with the reservoirs, whereby upon activation of the latent refrigerant the test samples may be safely transported and preserved in a chilled environment. The leaf members and the membranes may be flat except for portions corresponding in shape to the test samples, the portions forming a pocket for receiving a test sample. The pocket may be formed by a holding strap disposed over one of the reservoirs. The leaf members may alternatively bear a clip member for holding the test sample.

Abstract: The inventive method, which provides an accurate, objective and readily reproduceable characterization of the total colored appearance of a gemstone, includes the steps of identifying the main and overlay colors of an illuminated gemstone from among a predetermined set of primary colors by comparison of the stone with a series of reference color charts representing standard samples of the primary colors and of composite mixtures of the primary colors, identifying by comparison the proportion of overlay color to main color in each stone with respect to such proportion in the selected color chart to determine the overlay level, identifying the color saturation of the composite coloration of the gemstone by comparison with the selected color chart to determine the zone of coloration of the stone, and overlaying a color mask and the selected color chart to identify the degree of color masking present in the gemstone.

Abstract: A connector for use with threaded and push-on outlet couplings of pressurized gas supplies, the former having an exteriorly threaded cylindrical pipe termination and the latter having a tapering pipe termination, the connector comprising: a resilient tubular member, having a flat annular flange at one end and a narrower middle section; and, a cylindrical cap member having a threaded bore for engaging a threaded outlet coupling, partially closed at one end by an annular shoulder for pressing the flange into a sealing position between the cap member and the threaded coupling, the annular shoulder defining a bore enabling the cap member to be slidably retained in the narrower section and having an inwardly directed circular edge which can press a portion of the narrower section into a sealing position between the cap member and a push-on coupling after the flanged end of the tubular member has been pushed thereover, whereby the connector may be used with both threaded and push-on couplings.

Abstract: A breathing exerciser, comprising: first and second tubes; a lower cap member having bores for receiving one end of each of the tubes, the lower cap member having a passageway communicating between the first tube and a lower inlet/outlet opening; an upper cap member having bores for receiving the other ends of the tubes, and having a passageway communicating between both the tubes and an upper inlet/outlet opening; a floor member closing the lower end of the second tube; a floatable indicating member disposed in the second tube, the indicating member being upwardly movable during fluid flow into the upper inlet/outlet opening, through the first tube and out of the lower inlet/outlet opening, the amount of upward movement depending upon the rate of fluid flow; a valve assembly for adjusting the effective size of at least one of the inlet/outlet openings, for controlling the fluid flow rate required to move the indicating member over an effective range; and, openings in the second tube for calibrating the effec

Abstract: An apparatus for providing nebulizer treatments to a patient, including during ambulatory periods. The apparatus, which is portable and lightweight, includes a case, which case is internally provided with a compressor, capable of battery operation, which supplies compressed air to a nebulizer. The nebulizer is adapted to contain a medication which is atomized for inhalation by a patient through a mouthpiece or a facemask. The apparatus is sufficiently small and lightweight to be carried by a patient during ambulatory periods.

Abstract: The present invention related to a new compound useful for pharmaceutical purposes, namely, theophylline magnesium salicylate.

Abstract: Water-wettable anhydrous products, such as the powders and creams used in cosmetic and drug products, are admixed with 20% to 60% by weight, based on the weight of the total formulation, of a powdered polyethylene or powdered polypropylene polymer, to improve wettability characteristics. Denture adhesive powders prepared from an anionic/cationic adhesive combination, together with the powdered polyethylene or polypropylene polymer display particularly improved properties. The polyethylene or polypropylene polymer may also be admixed with other anhydrous products including dentifrices, vaginal powder sprays, and the like. Low molecular weight polyethylene powder, with an average molecular weight of from 1,000 to 3,500, is suitable for use in products of the invention. For the polypropylene, a molecular weight of from 120,000 to 350,000 is specified. The powdered polymers have a particle size of less than 422 microns.
