Abstract: A gas sensor system and its method of fabrication is disclosed. The sensor system comprises an optrode, light source, and a light detector. In a sensor for hydrogen gas, the optrode is comprised of a porous substrate into which an intimate mixture of reagent and catalyst is incorporated. The mixture reacts with the hydrogen to produce a color/intensity change in relation to the concentration of gas. The optrode further includes a reversing agent, boron, to restore the benchmark conditions of the sensor system in real-time. The method of fabricating the optrode includes the steps of cleaning; etching to achieve the proper porosity; incorporating the reagent, catalyst, and reversing agent using capillary action; and removing excess reagent and catalyst.

Abstract: A mobile station communicates with both a cellular network, by which it is assigned a mobile identification number, and to a cordless cellular base station utilizing the same cellular frequency range and communications protocol. The cordless cellular base station is preferably connected to a public switched telephone network and is assigned a landline number. The cordless cellular base station acts as a conduit between the mobile station and the public switched telephone network. When the mobile station comes within range of a cordless cellular base station, it deregisters automatically from the cellular network and register with the cordless cellular base station. Once the mobile station is communicating with the cordless cellular base station, the cordless cellular base station communicates with the cellular network to instruct the cellular network to route all calls for mobile identification number to the cordless cellular base station's landline number.

Abstract: A fluid suspension system has a valve including first and second valve parts coupled to a supporting structure and to a supported structure, respectively, and movable relative to each other in response to movements of the supporting structure and the supported structure relative to each other. One of these first and second valve parts has a port connected to a fluid spring of the suspension system, and the other of these first and second valve parts includes a fluid passage having an aperture at that port for a supply of fluid through that port to the fluid spring in a first relative position of these first and second valve parts. A fluid outlet in that other valve part is spaced from the port in a first relative position of the first and second valve parts, and communicates with that port for a removal of fluid from the fluid spring in a second relative position of the first and second valve parts.

Abstract: A preform for fabrication of a glass fiber optical transmission line is prepared by chemical reaction of vapor ingredients within a glass tube. Reaction, which may be between chlorides or hydrides of, for example, silicon and germanium with oxygen, occurs preferentially within a constantly traversing hot zone. Flow rates and temperature are sufficient to result in glass formation in the form of particulate matter on the inner surface of the tube. The particulate matter deposits on the tube and is fused with each passage of the hot zone. Continuous rotation of the tube during processing permits attainment of higher temperatures within the heated zone without distortion of the tube.

Abstract: Iron oxide films for "see-through" photomasks are deposited upon heated substrates by chemical vapor deposition from iron pentacarbonyl in the presence of oxygen. The solubility of the iron oxide film is found to be higher, the lower the temperature of the substrate during deposition. At temperatures below 160 degrees C., films are obtained which can be patterned at reasonable rates by photolithographic procedures using conventional mild etchants.

Abstract: Optical fiber preforms are produced by means of a duplex hot zone, a section of which is defined by an r.f. generated plasma fire ball. The process operates within a tube with gaseous precursor material reacting within the hot zone to result in deposited material of the desired preform glass composition. A "smoothing" region within the hot zone is defined by tube surface at a temperature sufficiently elevated to consolidate any particulate material resulting from reaction. In some aspects, the disclosed procedures may be regarded as Modified Chemical Vapor Deposition. Commercial significance resides in significantly increased throughput of preforms and, consequently, in fiber.

Abstract: An optical fiber fabrication method and apparatus are described which are capable of producing reproducible and uniform layers of fiber quality glass. The formation of a saturated stream of glass precursor vapor by condensation allows for the delivery of calibrated predetermined quantities of vapor to an appropriate fiber fabrication apparatus, thereby permitting improved fabrication characteristics.
