Abstract: A device for controllably releasing a fluid into an ambient environment. According to a particular embodiment of the present invention, the device comprises a housing having a fluid compartment and an orifice compartment disposed adjacent thereto and in fluid communication therewith via an orifice. The fluid compartment contains the fluid for release to the ambient environment. The orifice compartment includes a fluid exit opening covered by a removable sealing element and contains an initial quantity of fluid when the device is in an inactivated state. A fluid restrictor is disposed adjacent the orifice to restrict fluid flow from the fluid compartment into the orifice compartment in the inactivated state. A gas-generating cell is in selective communication with the fluid compartment such that gas generated by the cell is directed into the fluid compartment when the device is in an activated state.

Abstract: The invention described herein is a framed fluid delivery device that is made up of a fluid-delivery cartridge for the timed-release delivery of a fluid contained therein, and a frame assembly for retaining the fluid delivery cartridge. The frame assembly is made up of a base portion that facilitates the delivery of fluid released from the fluid-delivery cartridge, at least one side panel associated with the base, and that secures the fluid-delivery cartridge within the frame assembly proximate the released fluid delivering means. Additionally, a fluid delivery device is disclosed that includes a fluid-delivery cartridge for the timed-release delivery of a fluid contained therein, the cartridge having a bottom, a top, and sides, and a dispersion pad positioned proximate the bottom of the fluid-delivery cartridge, wherein the dispersion pad at least partially surrounds the sides of the fluid-delivery cartridge.

Abstract: The present invention is directed to a device for releasing a fluid. The device includes a housing having an interior region, a fluid contained within the interior region, and the ability to controllably release the fluid from the housing.

Abstract: A catalyst composition is disclosed which includes a p-aramid polymer supporting a catalyst agent. The composition exhibits improved catalytic activity when compared with a similar composition using m-aramid polymer as the support. The composition contemplates shaped and formed catalyst structures using p-aramid particles and fibers, as papers and fabrics, and as, for example, honeycomb and mats.

Abstract: A zinc alloy anode-based electrochemical cell, which generates gases and/or energy, is disclosed. The structure of the cell is such that a zinc alloy anode material is the integral part of housing and is in contact with an alkaline electrolyte containing minor amounts of corrosion inhibitors. The electrolyte which contains no zinc powder metal, may be in direct contact with the cathode thereby simplifying cell construction by elimination of a separator material. The cell is environmentally friendly, containing no mercury or cadmium or other toxic metals and is cost effective as it eliminates expensive amalgamated zinc powder and separator material.

Abstract: A storage stable fluid delivery device including a gas generator in which moisture (water) is involved in the gas generation reaction in which moisture containment is utilized to prevent or retard water loss as disclosed. The moisture containment may be a moisture impermeable membrane as a permanent part of the device and may be utilized in conjunction with the gas generator when the membrane has high gas permeability for the gas being generated. The fluid delivered by such device is typically a liquid having some particular utility in its environment. The liquid dispensed may be a pharmaceutical or some other liquid having a beneficial or curative effect upon an animal or human patient or it may be a liquid such as an insecticide, fumigant, fragrance or other liquid having a relatively high vapor pressure.

Abstract: An apparatus is disclosed for determining pressurization in a nuclear fuel rod and the like by measuring the increase in diameter of the fuel rod occasioned by the internal pressurization of the rod, and which includes an elongate receiving member having front and rear ends and an axial opening extending therein. A gauge is positioned in the axial opening and is adapted to coaxially surround the fuel rod and then measure an increase in diameter of a fuel rod caused by a pressure increase within the rod. The gauge is formed from a substantially C-shaped bracket having inner and outer surfaces, spaced distal end portions and a more thin medial portion, and with a strain gauge mounted on both the inner and outer medial surfaces. A microprocessor is connected to the strain gauges so that changes in electrical output from the strain gauges can be measured to determine the increase in diameter of the fuel rod upon pressurization of the fuel rod.

Abstract: A cathode for an air depolarized cell in which the hydrophobic catalytic cathode contains or is integrally coated with, on the surface adjacent the cell separator, an absorbent material such as the gelling material used in the anode. The absorbent material, integrated with the cathode surface, adheres the separator to the cathode thereby preventing delamination and provides an electrolyte reservoir for the hydrophobic cathode.
