Title: Self-cooling joint connection for abutting segments in a gas turbine engine
Inventor: STARKWEATHER JOHN H
IPC: F01D9/04
Filed: 1990-09-06
Abstract: SELF-COOLING JOINT CONNECTION FOR ABUTTING SEGMENTS IN A GAS          Abstract of the Disclosure A joint connection for abutting, circumfer-entially extending segments in a gas turbine engine, such as turbine nozzle segments,  includes a sealing member  which  is  insertable  between  longitudinally extending slots formed in the abutting side edges of two adjacent segments.  The segments are each formed with  a  number  of  grooves  which  are  longitudinally spaced along the  length of the  slots  therein,  and which extend beneath the sealing member carried within the slots.  A cooling air flow path is thus formed extending from one side of the sealing member,  into the longitudinal slot of each segment and then through the grooves to the opposite side of the sealing member so that the entire joint connection or seal region between the abutting side edges of the segments is cooled.

Title: Adaptive fir filter having restricted coefficient ranges
Inventor: DYER NIGEL P
IPC: H03H21/00
Filed: 1990-10-10
Abstract: ABSTRACT            AN ADAPTIVE FIR FILTER HAVING RESTRICTED COEFFICIENT                         RANGES       The adaptive FIR filter comprises a foreground non adaptive filter and a background adaptive filter. The background filter has N tap stages, some of which have their coefficient values applied to a summator. The output of the summator is compared with a predetermined constant K and produces an update enable signal This signal controls a switch which corrects the output of a discriminator. The discriminator compares the performance of the foreground and background filter, to either the foreground filter or the background filter to prevent the coefficient values of the foreground filter being updated by the background filter when the coefficient values of the background filter are unsatisfactory.

Mercury is removed from the hot waste gases, in a first embodiment, by distributing carbon and sulfur into the hot waste gas stream and then subsequently separating the mercury adsorbed or adsorbed by the carbon and sulfur particles downstream in the spray dryer absorber and baghouse filter.  In a second embodiment, elemental sulfur, in particulate form, is sprayed directly into the flue gas stream.  Other absorbents/adsorbents are discussed including diatomaceous earth, silica gel, activated aluminum oxide, aluminum or re-hydrate, zeolite or boiler fly ash.  An apparatus is disclosed for conveying the absorbent/adsorbent by means of a screw conveyor having a plurality of spiral slots in-the screw conveyor housing.  As a result,  the conveyed adsorbent/absorbent is equally divided to flow through a plurality of distributor pipes connected to the flue gas passages.  The distributor pipes are arranged to be respectively aligned below each of the spiral slots.  Flow can be adjusted by axially sliding sleeves located adjacent each of the slots to partially or fully cover a respective slot.

Patent CA-2038841-A1 (CA)
Inventor: COLMAN FREDRIC C
IPC: G01P13/00
Filed: 1991-03-22
Abstract: An optical motion sensor is provided for monitoring movement of a mechanical device, particularly such as an infusion pump of the type used for controlled delivery of medication to a patient.  The motion sensor includes a disk member mounted upon a selected mechanical output component driven by the  infusion pump,  such that the disk member undergoes displacement during normal pump operation.    The  disk  member  defines  a  pattern  of reflective and substantially nonreflective surface zones which  are  alternately  illuminated by  a  light  source during normal pump operation.  A light detector responds to the  level  of  reflection  from the disk member to provide an output signal which varies according to disk member displacement.  This output signal is connected to a controller for comparison with drive signals supplied to the infusion pump, to verify proper mechanical output operation of the pump.

Title: Electronic flash control circuit
Inventor: HARRISON GEORGE C
IPC: G03B7/16
Filed: 1991-03-25
Abstract: AN IMPROVED ELECTRONIC FLASH CONTROL CIRCUIT          ABSTRACT OF THE DISCLOSURE An improved electrical circuit for controlling the firing time of an electronic flash tube. The electrical circuit includes a storage capacitor that is chargeable by a suitable power source, a flash tube and an insulated gate bipolar transistor (IGBT), which can be activated between conductive and non-conductive states, that is connected in the discharge path of the storage capacitor through the flash tube. A signal responsive to a flash firing command is applied to the flash tube to initiate flash tube firing after the IGBT has been activated from its non-conductive to its conductive state. A flash terminating command is subsequently applied to the IGBT to terminate flash firing. The flash firing command and the flash terminating command are made independent of one another. By making these commands independent of one another, any undesirable effects of one or more electrical characteristics of the IGBT on flash tube firing is thereby eliminated.

Title: Microform printing system including a print scribe assembly for simultaneously printing additional micrographics
Inventor: WISE DAVID S
IPC: G03G15/04
Filed: 1991-10-18
Abstract: ABSTRACT OF THE DISCLOSURE A  microform  printing  system for  copying  a microform  image onto paper  includes  a print  scribe assembly in a second fiber optics system operative to simultaneously print selected annotation micrographics onto the copy, which micrographics do not appear on the original microform.  The print scribe assembly includes light emitting diodes and fiber optics strands extending therefrom to a scribe printing head, which is operative to transmit light from the light emitting diodes to the photoconductive reproductive drum of the system.   The scribe printing head is selectively movable relative to the photoconductive drum to change the relative position of  the  selected  micrographics  printed,  thereby  to accommodate different paper sizes or different positions on the same paper size.  The print scribe assembly is positioned  immediately  adjacent  the  drum  and  is operatively coordinated with masks along the main optics system to temporarily block part of the light in the main optics system which would otherwise interfere with printing the selected micrographics onto the paper at the selected location.
