Abstract: COPOLYMER COMPOSITION AND DELIVERY SYSTEM FOR PROVIDING A PROTECTIVE BARRIER FILM FOR THE SKIN                         ABSTRACT     A copolymer based film former composition and delivery system is disclosed for establishing a breathable, compliant, water insoluble barrier film for protection of the skin from exposure to, and irritation by, urine or fecal waste.  The film formed establishes a protective barrier film that aids in maintaining a normal skin environment such as at the site of an interface between the skin and the adhesive of an ostomy appliance.  In a preferred embodiment the copolymer comprises a plasticized solution of 50/50 n-butyl/iso-butyl methacrylate.  The film former is applied to the skin by delivery means adapted to essentially preclude cross-contamination, assure that the film intimately conforms to the skin, and in a preferred delivery system enables the essentially simultaneous removal of a previously deposited film with stomal contaminant thereon while establishing a new film formed of the copolymer composition.

Abstract: FLUID FLOW CONTROL DEVICE     ABSTRACT OF THE DISCLOSURE           A fluid flow control device comprises first, second, and third fluid pathways.  The first and second pathways are adapted for communication with separate sources of pressurized fluid.  The third pathway is coupled in flow communication with the first pathway and includes a flexible wall which forms an interface with a portion of the second pathway.  The flexible wall meters the flow communication between the first and third path-ways in response to fluid pressure fluctuations in the second pathway.  The fluid pressure in the first pathway is thereby elevated until substantial equilibrium with the fluid pressure in the second pathway occurs, and is thereafter continuously adjusted in response to subsequent fluctuations of fluid pressure in the second pathway to maintain this condition of substantial equilibrium.

Abstract: TITLE: METHOD OF AND APPARATUS FOR SPEEDING THE RESPONSE     OF AN AIR BAG INFLATOR AT LOW TEMPERATURES          ABSTRACT OF THE DISCLOSURE:     An air bag inflator for the passenger side of an automobile includes an elongated, tubular housing having a plurality of perforations in its cylindrical wall for discharging gas.  Within the housing are a gas generant composition, an igniter and filtering  screens.  The per-forations are normally sealed with 0.003 inch (0.0762 mm.) thick non-tempered aluminum foil which is easily ruptured by the gas pressure when the inflator is ignited.  The foil, in addition to serving as a hermetic seal for protect-ing the gas generant and igniter from moisture and dust, insures that the gas pressure will reach a certain, threshold level before being discharged into an air bag.  In very cold weather the inflator attains its peak pressure considerably more slowly than in warm weather.  As a result, the air bag may be inflated either too slowly or insufficiently to perform its intended purpose.  In order to preclude this from happening at least some of the perforations in the housing are covered with an additional or buttressing layer of thicker (0.006 inch; 0.1524 mm.) non-tempered aluminum foil, so that the threshold gas pressure necessary to rupture these seals is raised.  This shortens the time for attaining peak gas pressure within the tubular housing and results in faster, more satisfactory inflation of the air bag when the ambient temperature is low.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to an improved integral manifold for a sprue gated multi-cavity injection molding system and a method of manufacturing the same.  The manifold has an inner body portion which fits into a hollow retaining ring portion to define a circular peripheral space between them.  The inner body portion is formed of a corrosion and abrasion resistant material such as stainless steel and has a number of straight melt ducts extending through it from a common inlet to spaced outlets each leading to a central bore in separate heated nozzles.  The peripheral space contains an electric heating element surrounded by a highly conductive material such as copper.  The manifold is manufactured by assembling the retaining ring portion on the inner body portion with the heating element in the space between them.  A filler tube is located on the retaining ring portion in alignment with a filler duct therethrough and all the joints are sealed by brazing the assembly in a vacuum furnace.  A copper slug is then inserted into the filler tube and the assembly is again heated in a vacuum furnace to cast the copper into the peripheral space around the heating element.  This provides an integral unit with an improved combination of the characteristics of corrosion and abrasion resistance and thermal conductivity, as well as straight melt ducts which facilitate cleaning.

In a special embodiment of the invention where the cooling step is effected outside the mold, the cooling under the shrinkage resisting pressure is below 100°C., even down to room temperature and lower, before the shrinkage resisting pressure is released from the hollow article.

Abstract: MULTIPLE AMPLIFIER INTERCONNECTION       FOR OPTIMAL SENSITIVITY          Abstract To obtain optimal operational sensitivity from an amplifier connected to a source of electrical signals, a technique utilizes multiple amplifiers connected together. The technique determines the number, N, of amplifiers to be used and whether they should be connected in parallel or series in order to optimize the sensitivity of a given type of amplifier.  Accordingly, multiple interconnection of amplifiers may be used in lieu of noise matching with transformers to minimize the excess-noise figure of the multiple amplifier circuit.  The technique capitalizes on the advances in integrated circuit amplifier design, such as compactness and sideband performance, while providing lower loss and higher reliability through redundancy.

Abstract: ABSTRACT OF THE DISCLOSURE:           In a switched capacitor circuit, in order to eliminate leakage of a power supply noise component to a signal line through an input capacitance of an operation amplifier, (1) an operating current of at least a first, differential stage among stages of the operational amplifier is regulated by a current regulation bias circuit, and (2) a power supply noise component having the same phase as that of an input signal is applied to the gate of a transistor of a gain stage, thereby stabilizing the operating point.  In order to eliminate leakage of the power supply noise component to the signal line through a parasitic capacitance of an analog switch, (3) a dummy switch is used to detect a signal corresponding to the leakage component of the power supply noise component to the signal line, and an inverted signal having the opposite phase to that of the signal corresponding to the leakage component is applied to a substrate of the analog switch, thereby cancelling the actual leakage component.
