Abstract: A method is provided for hermetic packaging of unimpregnated and impregnated adsorbents which provides for improved packing densities, reduced attrition losses, and reduced exposure of the adsorbent to environmental or other contamination. Furthermore, the method inherently provides for identification of instances of packaging failure. The method entails hermetically sealing a collapsible gas and vapor impermeable vessel containing an adsorbent which is at an elevated temperature. Subsequent cooling of the adsorbent results in the production of a partial vacuum within the vessel. As a result of this partial vacuum, the environmental atmospheric pressure collapses the vessel to firmly compresses the adsorbent in a hermetically sealed low-pressure environment to provide the stated advantages.

Abstract: A gas sensor (8) includes a body (10) that is shaped to define a chamber (14). An electrolyte (34) is contained in the chamber (14) and three electrodes (26, 28 and 30) that are located on an electrode substrate (24) are disposed in contact with the electrolyte. The body (10) is electrically connected to the three electrodes. A cover (36) engages the body (10) to enclose the chamber (14). A resistor array (58a-58n) is located between the cover (36) and the electrode substrate (24). The resistors (58a-58n) are coated with a compound that emits a predetermined gas in response to temperature increase. To test the sensor (8) voltage is selectively applied to the resistor array (58a-58n) to introduce the gas to the gas diffusion path of the sensor (8).

Abstract: A method for removing a coating on a surface by applying a treatment composition layer to the coating to be removed. The treatment composition layer is made up of (Is) a first material selected from the compounds of sodium and potassium silicates, sodium and potassium phosphate, calcium silicate, iron and aluminum sulfates. An abrasive is injected against the coating to be removed so that the treatment composition layer and coat to be removed are removed and any hazardous material in the layer to be removed is contained.

Abstract: The present invention relates to pre-ignition lubrication mechanisms for internal combustion engines, and more particularly to a pressurized pre-combustion oiling mechanism for use with internal combustion engines. The present invention provides an accumulator tank containing either air or an easily condensible gas. The pressurized oil causes the air or gas in the bag to become compressed, causing a decrease in occupied volume in proportion to the pressure induced by the oil to allow the oil to occupy a suitable portion of the tank. In the preferred embodiment of the invention, the pressurized oil would cause the condensible gas to undergo a phase change and liquify. Conventional valving known in the state of the art is provided to allow the accumulated pressurized oil to be used prior to a subsequent engine startup, and conventional electronic control systems are provided to engage and disengage the aforementioned valves for a proper pre-ignition lubrication sequence.

Abstract: A process for concentrating and destroying the perchlorate and nitrate anions present in ground water and drinking water sources is disclosed. In the process, the perchlorate and nitrate anions present in feed water are concentrated into a much smaller effluent stream. A typical process configuration involves using a continuous contacter apparatus known as ISEP wherein the perchlorate present in feed water is adsorbed on to an ion-exchange resin resulting in a perchlorate-free treated water. The ISEP unit also incorporates a regeneration zone where the adsorbed perchlorate is effectively removed from the resin using relatively low volumes of concentrated brine solution as the regenerant. The waste from the ISEP unit is a concentrated brine solution containing perchlorate and other anions that may be present in the feed stream.

Abstract: A closure is provided with a thread configuration adapted for snap-on or screw-on application to a container neck finish. Preferably the closure and neck finish contain eight or nine mating continuous or discontinuous threads for this purpose. The present invention preferably provides at least one annular sealing bead depending from the outer surface of the closure valve which are compressed against the inner surface of the container neck to form a seal as the closure is snapped onto the container neck. Optionally, sealing engagement between the closure and the mating portions of the exterior wall of the container neck may be further improved by including one or more annular sealing beads on the interior surface of the closure depending annular skirt.
