    摘要: A telephone system is provided which requires no central office. All the stations on the system are interconnected by a single line or cable and each station includes a computer which carries out the necessary switching. Each station is then able to call any other station, or to respond to a call, without requiring any central office. Frequency division multiplexing is used to permit a number of conversations to be carried on simultaneously and two frequencies are assigned to each conversation to permit duplex operation. A page capability is also provided.

    摘要: The present invention provides an electrochemical sensor for the detection of an analyte, wherein the output or response of the electrochemical sensor approximates the dose-response behavior of a living organism upon exposure to the analyte. The electrochemical sensor comprises a housing including an inlet port therein to allow the analyte to enter the housing. The electrochemical sensor further comprises at least a first electrode and a second electrode within the housing. Electrical conductivity is maintained between the first electrode and the second electrode via an electrolyte system present within the housing. The electrochemical sensor further comprises a resistor in series electrical connection with the first electrode and the second electrode. This resistor has a resistance adapted to be sufficiently high such that the output of the electrochemical sensor over time at a particular concentration of the analyte approximates the response of a living organism to the analyte over time at that particular concentration. The present invention also provides a method of using an electrochemical sensor as describe above.

    摘要: A lithium iodine primary cell is provided that comprises a lithium anode encasing member having an aperture therethrough. Positioned within the anode encasing member is a cathode which consists essentially of a mixture of organic charge-transfer complex and iodine. The cathode includes a current collector having a lead portion with an insulating coating positioned through the aperture in the encasing member. Optionally, the current collector may include an insulating frame around its periphery to prevent electrical contact with the anode. A lithium iodide electrolyte is coextensively positioned between and in contact with the inner surface of the encasing member and the cathode.The method for making the cell includes forming a receiving vessel of lithium and positioning the cathode current collector therein. The cathode material is heated to a flowable consistency and the vessel is completely filled with the heated cathode material. The completely filled vessel is chilled to a temperature sufficient to solidify the heated material; and, while in the solidified state, the vessel is sealed by positioning a lithium cap on the solidified material and cold welding the cap under pressure to the receiving vessel to form the lithium anode encasing member. Second and third redundant encasements are effected by placing a thin layer of iodine-resistant cement and an outer layer of iodine resistant film (preferably a fluoropolymer), respectively, over the receiving vessel. These encasements provide additional electrical insulation from a hermetically sealed outer metal case finally positioned over the assembly.

In general, the present invention provides an electrochemical sensor for the detection of an analyte comprising a first metallic housing member and a second metallic housing member. The first metallic housing member and the second metallic housing member are brought together in sealed connection to create a sealed enclosure therebetween. Contained within the enclosure are a first electrode, at which the analyte reacts, and a second electrode, at which a reaction complimentary to the reaction of the analyte at the first electrode takes place. An acidic electrolyte is also contained within the enclosure of the first metallic housing member and the second metallic housing member.

    摘要: A compact electrochemical gas sensor for detecting toxic gases is described which utilizes a fluted electrically-conducting feedthrough for making the electrical connection from outside the sensor with each electrode inside the sensor. Utilization of the fluted electrically-conducting feedthroughs significantly reduces the number of parts needed to make the sensor as well as reduces the likelihood of electrolyte leakage from the sensor. Additionally, the electrochemical toxic gas sensor may use a gas permeable membrane instead of a gas porous membrane.

    摘要: A gas detection device is provided comprising an exterior housing in which an active pelement and a compensating pelement are disposed. The gas detection device further comprises a porous frit seated within a distal end of the exterior housing to separate the active pelement and the compensating pelement from the surrounding environment. The porous frit is adapted to prevent flashback into the surrounding environment while allowing movement of environmental gas through the porous frit to contact the active pelement and the compensating pelement. The gas detection device further comprises a flow guide for directing flow of environmental gas into the gas detection device disposed adjacent the exterior side of the porous frit. The flow guide comprises an inlet port through which a forced flow of environmental gas is pumped to pass through the porous frit and into the exterior housing in a direction generally parallel to the axis of the exterior housing. The flow guide also comprises an outlet port through which gas may exit the exterior housing. A gas detection device is also provided in which the electrical resistance of the compensating pelement is measured to determine concentration of combustible gas at combustible gas concentration levels above a predetermined concentration level set equal to the LEL (Lower Explosive Limit). The gas detection comprises a circuit for reducing current passing through the active pelement when the gas detection device is being used above the predetermined concentration level.
