Patent CA-2020989-A1 (CA)
Inventor: PEASE WALTER
IPC: E01H5/04
Filed: 1990-07-12
Abstract: A  snow  deflection  system  for  use  with  vehicle propelled snowplows  is designed to deflect snow which passes over the plow or moldboard away from the propelling vehicle.  The top margin of the moldboard has permanently attached to it belt means which extends  forwardly and downwardly  to  control  and  maintain  the  position  of generally all of the snow in general close proximity with the moldboard.  By mounting arcuate foil means in spaced apart relationship above the top margin of the moldboard and  the  belt  means,  an  airflow space  is  defined therebetween,  thereby effectively directing the flow of snow above the moldboard through the airflow space and directing it downwardly away from the snowplow vehicle.

Filed: 1990-07-12
Abstract: ABSTRACT OF THE DISCLOSURE   A  gear-actuated  mechanical  clearance  control apparatus  is  operable  for  controlling  the  clearance between rotor blade tips and the casing shroud of a gas turbine engine.  The apparatus includes a pair of annular rings which extend about the casing shroud,  a shroud hanger disposed between the casing and an opening in the casing  and between  the  annular  rings,  and  a  shroud segment defining a circumferential portion of the casing shroud and disposed in the casing opening.  The apparatus also has an actuating mechanism which includes driven gear sectors on the annular rings which face toward one another and a gear disposed between the annular rings and having a peripheral driving gear sector which intermeshes with the driven gear sectors of the annular rings.  Upon rotation of the gear, the annular rings undergo opposite circumferential movement causing radial movement of the shroud  hanger  and  the  shroud  segment  therewith  to establish the clearance between the shroud segment and rotor blade outer tips.

Title: Polymer concrete composition for cementitious road repair and overlay on wet and dry surfaces
Inventor: SELLSTROM KATHY B
IPC: C08L63/00
Filed: 1990-12-19
Abstract: ABSTRACT OF THE INVENTION                           (D#80,925-F) A polymer concrete system has been discovered which is useful in road overlay and repair in both wet and dry conditions.          The binder for this aggregate-filled system consists of a liquid epoxy resin and triethyleneglycol diamine or tetraethylene glycol diamine combined with polyoxypropylene glycol diamine curing agent.  A piperazine accelerator ensures adequate strength development after short cure times at ambient temperatures.        The binder-aggregate system is relative flexible, has excellent compression and flexural strength and adheres well to the substrate.  The system is distinguished by its binding strength to smooth or rough surfaces whether the surfaces are wet or dry.

Title: Combined valve modular control
Inventor: COTTER JONATHAN P
IPC: F15B11/00
Filed: 1991-01-22
Abstract: A valve modular control panel having a gas supply module at one end of a row of valve modules and a bleed module at the other end. Each valve module is individually controlled by its own valve mechanism. Gas under pressure is suppled to all of the valve modules from an inlet in the supply module by a passage running through all of the valve modules and terminating in the bleed module. A bleed passage runs through the valve modules and into the bleed module. All valve modules are bled through the bleed module. The bleed module is also capable of exhausting the supply passage. The panel can be expanded or contracted to include any number of valve modules which are releasably secured together by a series of nuts and tie rods.      A protective shield for the panel can be adjusted in size depending on the number of modules in the panel.

Title: Production of diisopropyl ether
Inventor: HARANDI MOHSEN N
IPC: C07B61/00
Filed: 1991-04-25
Abstract: ABSTRACT                 PRODUCTION OF DIISOPROPYL ETHER         In a diisopropyl ether production process the distillation step for the separation of aqueous IPA recovered from the DIPE extraction operations is modified to avoid carrying out the distillation under conditions that yield IPA-water azeotrope.  The overhead and bottom streams from an aqueous IPA fractionation process operated under off-azeotrope conditions in DIPE production are recycled, respectively, to the DIPE reactor and extractor operations.  Recycling the water and IPA overhead mixture eliminates the requirement for adding fresh water to the DIPE reactor.  Returning the water and IPA bottom stream to the extractor reduces the requirement for distilled water addition to the extraction step.  A less complex and costly aqueous IPA separation process results.

Title: Electrodeless hid lamp with microwave power coupler
Inventor: LAPATOVICH WALTER P
IPC: H05B41/24
Filed: 1991-05-09
Abstract: An electrodeless lamp may be formed with a capsule having a radiant energy transmissive material defining an approximately cylindrical enclosed volume having an external length less than 20.0 millimeters, and an outer diameter less than 8.0 millimeters. The enclosed volume is filled with a lamp fill excitable by a high frequency electromagnetic field to produce radiant energy. The small size capsule produces a particularly efficient, orientation tolerant arc discharge. The arc is then highly stable as to position, yielding a good optical source to design for. The temperature gradient is small, thereby yielding little thermal strew on the capsule. An electrodeless HID headlamp system may be formed with the efficient capsule from a radio frequency source operating from a the power supply of a typical automobile. The headlamp system includes a high frequency power source, a transmission line, a coupler, an excitable lamp fill captured in a lamp capsule, a reflector and a lens.

Filed: 1991-10-08
Abstract: This  invention provides for a batch and continuous process with countercurrent recycle of bleaching filtrates  for the    delignification and   bleaching   of   pulp.   Oxygen delignification of pulp is achieved in excess of from about 50% to  about  76%  as  measured  by  kappa numbers, while the pulp viscosity is minimally decreased in the range of from  about  2 to  about 5 cps. Bleaching of delignified pulp is achieved with peroxy compounds and ozone and pulp brightness of from about 82 to  88  ISO can be achieved with pulp containing zero level TOX from chlorine based bleaching chemicals and zero level  of  AOX in  the bleach effluents. Higher brightness of from about 90 to about 92 ISO can also be  achieved  by  addition  of  very  low levels  of  chlorine  based  bleaching chemicals. Corresponding bleach effluents contain  less  than  200  ppm  AOX.  Bleaching filtrates  can be recycled for pulp washing and for use with an organosolv pulping process which results in significant  energy savings and   mitigation  if  not  elimination  of  pollution typically  associated  with  chlorine  based  bleaching.   This invention  also relates to bleach pulp product derived from the process  and to an apparatus for carrying out the process.

Title: Zero clearance anti-extrusion rings for containment of ptfe packing
Inventor: HUTCHENS WILBUR D
IPC: F16J15/20
Filed: 1991-10-11
Abstract: A packing containment assembly for sealing an operating member such as a shaft or stem in a fluid control valve, particularly where PTFE packing is used. A pair of zero clearance anti-extrusion rings of PEEK material are mounted in the shaft with the PTFE packing therebetween. Each ring has an inner diameter slightly less than the shaft outer diameter to form an interference fit. The rings are split with a scarf cut to provide an overlapping joint and enable mounting of the rings on the operating member. A male adapter PEEK ring matches a V-type female packing ring which significantly reduces the amount of PTFE packing needed for a reliable seal. A step cut PEEK zero clearance anti-extrusion ring could be used as well as a fractured carbon ring.
