Patent CA-2091724-A1 (CA)
Title: Tools for installation of both tnaged and tangless wire inserts
Inventor: COSENZA FRANK J
IPC: B25B27/14
Filed: 1993-03-16
Abstract: A multi-purpose tool for inserting tanged or tangless mire inserts in a pre-threaded hole. In the case of a tangless insert, the tool nose passes freely through the internal diameter of the insert until a tool pail automatically engages a cut out formed in the tangless insert. Once the proper depth of the insert in the parent material has been achieved, the tool stops rotating and is reversed for proper disengagement, the installation being complete.      In the case of a tanged insert, the nose of the tool does not pass freely through the insert due to the presence of the tang that is blocking its way. As the tool rotates through the internal diameter of the insert, a ledge formed on the nose portion of the tool forces the insert to wind itself in the threads of the parent material. The pawl used to install the tangless insert is positioned directly behind the nose of the tool and remains inoperable in the retracted position since the insert does not have a cut out provided for it. After proper depth of the insert has been achieved, the tool stops rotating and is reversed for proper disengagement.

Title: Comminuting method and apparatus
Inventor: HUGHES JOHN H
IPC: B02C18/06
Filed: 1991-12-20
Abstract: The comminution of solid materials, such as stumps and wood waste, into particulate form is accomplished by introducing the material to be comminuted into a tub (24). The tub (24) is rotated to induce a circular motion to the material. Simultaneously, a disk (32) positioned at the bottom of the tub is rotated, preferably in the opposite direction to the tub, in a plane parallel to the tub bottom. The disk (32) has teeth (34) thereon that impact the material in the tub. A screening means at the bottom of the tub is sized to keep the material in the tub until it reaches a desired particle size, at which time the particles can leave the tub through the screening means (44) and enter a collection chamber (49). The particles are removed from the collection chamber (49) by being entrained in an airstream that passes adjacent an opening in the collection chamber. Preferably, the teeth (34) in the disk are individually replaceable and are symmetric so that once one side is worn the tooth can be reversed in its amount and used again.

Title: Apparatus and method for venting and for monitoring oil levels in marine outdrives
Inventor: FISHER CHELSEA G
IPC: B63H21/38
Filed: 1993-06-24
Abstract: APPARATUS AND METHOD FOR VENTING AND FOR MONITORING OIL LEVELS IN MARINE OUTDRIVES          ABSTRACT OF THE DISCLOSURE      Oil venting and monitoring apparatus for marine outdrives.   The apparatus includes an oil monitoring reservoir suitable for locating inside the boat.  The reservoir is in fluid communication with the fully oil flooded head of the marine outdrive.   The reservoir can be observed for an indication of oil level and oil condition.     A clear plastic oil reservoir may be used to enhance visual observation.  Unlike conventional outdrives, the oil reservoir is convenient for the addition of oil as necessary during and after operation.   The apparatus is preferably designed with at least a one inch (1") diameter oil fill hole and typically is of one (1) quart or more oil capacity, so that an entire quart of oil can be quickly added to the system at one time.   Also,  audible and visual warning systems are included to warn the operator of a low oil condition, or of excess metal in the oil.  The reservoir includes an atmospheric vent at the upper reaches thereof, which allows vapors to migrate inward and outward as the oil and engine parts expand and contract, to avoid creation of a vacuum or pressure within the outdrive head, which event  causes  seals to  allow  migration  of contaminated water in outdrives not equipped with this system.

IPC: F24C3/00
Filed: 1993-09-20
Abstract: This gas burner system provides an asymmetrical flame pattern together with the presence of glowing embers around and beneath non-combustible logs, closely resembling the overall appearance of a  natural wood  fire  in  a  fireplace.  The  burner  system  has a plurality of gas burner pipes arranged in a fan-out pattern on a log mounting plate to provide gas throughout the logs arranged over the plate. Air supply openings are formed at selected areas in the mounting plate to permit fresh air to pass only therethrough from below the mounting plate to the fire. Air deflectors are located adjacent to the openings and lava rock and/or mineral fibre pieces are placed below the logs over the gas burner pipes to disperse the combustible gas throughout the log arrangement. The provision of openings  and  deflectors  create  air  currents  flowing  over  the surfaces of the logs to prevent the flames from impinging on the log surfaces for  reducing the formation of carbon deposits and carbon monoxide gas.

Title: Fcc process using reactor riser disengager with suspended catalyst separation zone
Inventor: CETINKAYA ISMAIL B
IPC: B01J8/26
Filed: 1994-02-22
Abstract: Operation of an FCC process is improved by using a novel reactor riser disengager configuration which suspends catalyst in a disengagement zone in a riser proximate or above the riser cyclone inlets to achieve a suspended catalyst density that is higher than the flowing catalyst density in the riser. The suspended catalyst provides a disengagement zone that enhances the separation of catalyst from product vapors. The riser operates in a manner that prevents any substantial discharge of product vapor from its upper end. The arrangement also provides a convenient method for venting stripping vapors into a closed reactor cyclone system.
