Title: Dual sample cell gas analyzer
Inventor: MCCLATCHIE EDWARD A
IPC: G01N21/35
Filed: 1988-08-31
Granted: 1993-03-30
Abstract: DUAL SAMPLE CELL GAS ANALYZER           ABSTRACT A non-dispersive infrared gas analyzer is disclosed that accurately measures the concentration levels of a plurality of gases within a gas mixture. The analyzer includes first and second sample cells and is utilized advantageously for the measurement of NOx and hydrocarbon gas present in the exhaust of an automobile engine.  The gas mixture of the exhaust is chilled before entering the first sample cell to remove a substantial amount of the water vapor from that sample cell to facilitate measurement of the NOx gas.  The second sample cell receives the gas mixture in an unchilled state to allow for accurate measurement of the hydrocarbon gas.  The analyzer includes processors which are utilized to further correct the NOx measurement and which also interact with each other to provide an output data stream that is representative of the concentration levels of the gases that are being analyzed.

Abstract: An apparatus and method for recovering a conductive metal from a liquid which contains that metal, and a method for recovering that metal using that apparatus.   The apparatus includes a generally closed non-metallic  recovery container  defining a cavity, for containing the liquid.  A first electrode is supported and affixed within the cavity.  A second electrode is composed of a thin film applied to the inside surface of the recovery container, the film including as its main constituent the same metal as that to be recovered from the solution.  Finally, a power supply is electrically connected, positive to the first electrode and negative to the second elec-trode, thus causing the metal from the solution to be deposited on the film electrode,  lining the inside surface of the recovery container with the metal to be recovered.  In one embodiment the apparatus includes a separate holding container for holding the solution, and the recovery container is placed in liquid commu-nication with the holding container.   During the reaction,  solution is circulated from the holding container into the recovery container and back by a pump.  The recovery container may be mounted above the holding container, and the center electrode tubular, to be used as part of the return path of the solution to the holding container.

Granted: 1993-02-23
Abstract: ABSTRACT OF THE DISCLOSURE    An apparatus is disclosed for cleaning a porous cover of a press roll of a papermaking machine.  The apparatus includes a hydrostatic bearing disposed adjacent to the porous cover, the bearing defining a concave surface for cooperating with porous cover.  The bearing defines a fluid conveying passageway having a first and a second end.  The first end of the passageway is connected to a source of pressurized fluid and the second end is in fluid communication with the concave surface such that in use of the apparatus, when the porous cover of the press roll rotates, the fluid passes through the passageway and along the concave surface and between the concave surface and the porous cover.  The pressurized fluid flow inwardly through the porous cover for flushing contaminants lodged within the porous cover outwardly away from the porous cover thereby inhibiting the buildup of contaminants on the external surface of the porous cover that would otherwise impair the water absorbing capabilities of the cover.

Abstract: A    pneumatic    pressure   control   arrangement   for controlling  the brakes of railway vehicles.  A manual brake command  controller  converts a selected brake position into a  corresponding  electrical  signal.  An application magnet valve  is  connectable  to a source of air pressure and to a storage  device.    A release magnet valve is connectable to atmosphere  and  to the storage device.  An electropneumatic transducer  senses  the  pressure  in the storage device and provides  a  feedback signal.  A microprocessor receives and compares  the  electrical signal with the feedback signal to develop  an  error  signal  which  initially  energizes  the application  magnet  valve and the release magnet valve upon request  of  braking  effort,  and which subsequently pulses the  application  magnet  valve  when  the  pressure  in the storage  device  is  within a preselected control range, and which  finally deenergizes the application magnet valve when the  pressure  in the storage device is within a preselected deadband range to cause a lap condition.

Abstract: A preform is formed by providing a substantially longitudinally continuous core member (10) and affixing it to a starting member (12). Particulate material is applied to the exterior surface of the core member to form an adherent coating (18) having an index of refraction less than that of the core member (10). The starting member (12) and the core member (10) are longitudinally translated while simultaneously applying the adherent coating (18) of particulate material to the core member to form a continuous and substantially homogeneous adherent coating of substantially uniform thickness. The composite so formed is simultaneously or subsequently heated to sinter or consolidate the applied adherent coating thereby forming a solid blank which may be heated to the drawing temperature of the material thereof and drawn to reduce the cross-sectional area thereof forming a substantially continuous optical waveguide, the core member (10) comprising the core while the consolidated coating (18) comprising the cladding of the optical waveguide. The adherent coating (18) may be sintered or consolidated to form a solid blank and thereafter drawn in a separate operation or subsequently drawn as part of a continuing operation. As an alternate, the optical waveguide may be drawn immediately following the sintering or consolidation step employing a single heating of the structure.

Abstract: A thermoplastic tape is wrapped around a package and is tightened by the disclosed strapping or banding apparatus. The ends of the plastic tape can be welded together by a combined strapping and sealing apparatus or even with a separate sealing apparatus. The strapping apparatus includes a positioning system which ensures that a slotted wheel intended for tightening the plastic tape, once the operating cycle is complete, always assumes an optimum position for the re-insertion of the plastic tape. The use of the strapping apparatus is thereby substantially facilitated, since the operator normally does not have any hands free to adjust the slotted wheel that would otherwise be necessary for tape insertion.
