Title: Process for controlled n2o decomposition in an n20-containing gas stream
Inventor: RILEY BRIAN W
IPC: B01D53/86
Filed: 1993-03-23
Abstract: "PROCESS FOR CONTROLLED N2O DECOMPOSITION      IN AN N2O-CONTAINING GAS STREAM"                           ABSTRACT The exothermicity attending decomposition of N2O to nitrogen and oxygen can lead to a multiplicity of process difficulties associated with high process temperatures. The process of the invention solves three difficulties by cooling a portion of the exit gases depleted in N2O from the decomposition zone and then recycling at least a portion of the resulting cooled gas stream to the N2O-decomposition zone. The process is amenable to process control to afford a very stable process largely independent on the particular catalyst used for N2O decomposition. Where the N2O-containing waste gas stream also contains NOx, it is often highly desirable to pretreat the stream to remove NOx prior to the N2O-decomposition zone.

Title: Plunger for reciprocating plunger pump
Inventor: LEACH JAMES K
IPC: F04C9/00
Filed: 1993-04-06
Abstract: PLUNGER FOR RECIPROCATING PLUNGER PUMP            Abstract of the Disclosure A plunger for a reciprocating plunger pump comprises an elongated metal bar in which at least the elongated cylindrical pumping end section of the bar is formed by casting the bar generally in the shape of the finished plunger.  The casting is made from a cast iron such as the family of cast irons available under ASTM designation A 532.

IPC: G01F23/40
Filed: 1992-08-06
Abstract: A level gauge for a tank, of the driven sensor type, comprises essentially: a drum (200) around which is wound a thread on the end of which is suspended a driven level sensor; a reversible servomotor (150) driving the said drum; means (350, 351) for driving the drum in both directions; means for recording drum rotation; means (310, 301, 302) for detecting a variation in the force in the thread, said force being directly related to the relative position of the sensor with respect to the level being measured. According to the invention, the said means for detecting a variation in the force in the thread comprise an element (310) rotatably mounted about a horizontal axis. Its oscillation is limited by damping means (305 to 311) and movement of the element (310) enables the force exerted on the thread to be measured.

Title: Linear scan method and system for energizing an optical fiber bundle
Inventor: GRACE KENNETH P
IPC: G02B6/40
Filed: 1993-05-12
Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for relatively moving energy across an array of optical fibers. The energy may be scanned across the fiber array. A dielectric mirror mounted on a galvanometer scanner is moved so as to cause successive pulses to irradiate different segments of the fiber optic array.  As a result, each fiber receives radiation having sufficient fluence while reducing the energy per pulse (or the cw equivalent).  Rather, than move the energy across the fiber array, the fiber array itself may be moved.  One possible manner of movement is use of a piezo electric stack.

Title: Staged furnaces for firing coal pyrolysis gas and char
Inventor: DAMAN ERNEST L
IPC: C10J3/72
Filed: 1993-05-14
Abstract: STAGED FURNACES FOR FIRING COAL PYROLYSIS GAS AND CHAR        ABSTRACT OF THE DISCLOSURE     A pyrolyzer unit and two-staged furnaces are provided in a compact furnace assembly for combusting coal to generate power.        Coal is reacted in the pyrolyzer to produce a clean hot fuel gas and char.  The hot fuel gas is combusted in the first-stage furnace, which contains a high-temperature heat exchanger utilized to heat a pressurized air stream for expansion in a gas turbine and a heat exchanger for superheating steam for expansion in a steam turbine to produce power.  Char is combusted in the second-stage furnace and the  resulting  combustion  products are  mixed  with  primary combustion gas from the first-stage furnace to product a secondary combustion gas and preheat the pressurized air stream, and also to superheat steam.  The heated air stream is expanded in a gas turbine to produce shaft power to drive an air compressor and an electric power generator.  The hot secondary combustion flue gases and hot air exhaust from the gas turbine are used for preheating pressurized water to generate the steam for the steam turbine cycle.

Filed: 1993-06-18
Abstract: An apparatus for stretching tubular material with at least one closed end on a stretcher, in particular for stretching stockings, pantyhose, and the like on an elongated stretcher, is described, in which the tubular material is pulled onto the stretcher by means of belt drives. Each stretcher has at its lower end an end member at which there is provided a sensing device by means of which the belt drives are shut off as soon as the closed end of the tubular material arrives in the region of the end member. With the sensing device, the belt drives are reliably shut off regardless of the length of the tubular material being pulled on, which not only prevents slippage of the drive rollers of the belt drives, but also ensures complete pulling onto the stretcher.

IPC: D06N3/06
Filed: 1993-06-30
Abstract: ABSTRACT    The invention relates to a breathable, plastic film, useful as a wall covering material.  A low boiling additive, such as water, is added to a plastisol before extrusion.  During extrusion and curing of the plastisol into a film or coating, the low boiling additive is volatilized and the resulting evolved gas perforates the forming film.  In this manner a permeable plastic film, such as vinyl, is produced.
Patent CA-2099739-A1 (CA)
Inventor: FUENTES JAMES JOSEPH
IPC: H04B7/26
Filed: 1993-06-29
Abstract: This invention relates to a method and apparatus for offering wireless telecommunication service. Pairs of the transceivers of a wireless cell site aredirectly interconnected. When a request for service is received, a controller allocates a pair of the transceivers to handle the call. If the call is to the public switched telephone network, an unconnected transceiver is connected to a switching system, such as a toll switch, and a protocol converter converts between call control messages to and from the cell site and call control messages to and from the toll switch. If the cell site has directional antennas, a pair of transceivers connected to the directional antennas for serving the calling and called stations is selected; transceivers connected to an omni-directional antenna can be used for overflow traffic and for traffic between the toll office and the cell site. Advantageously, the need for switching is avoided by selecting appropriate transceiver pairs and tuning the mobile stations to the correct channels.
