Patent CA-2034540-A1 (CA)
Title: Tire mold vent plug and method
Inventor: WISE THOMAS E
IPC: B29C33/10
Filed: 1991-01-18
Abstract: ABSTRACT     A mold for curing a green tire which is made of an elastomeric material capable of flowing prior to curing.  The mold comprises a surface defining a cavity in the mold for receiving the green tire.  A passage communicates the cavity with the exterior of the mold.  A vent plug is located in the passage.  The vent plug has an opening extending therethrough communicating the cavity with the passage.  Elastomeric material may flow into the opening to form a projection extending from the tire as the green tire is pressed against the surface defining the cavity during a molding operation. The vent plug has a portion extending into the cavity a predetermined distance from the surface to form a recess in the tire adjacent the projection.  The recess provides a space that the projection may deflect into to prevent shearing off of the projection during removal of the tire from the mold.
Patent CA-2035299-A1 (CA)
Inventor: KATZ LEWIS J
IPC: F02B1/04
Filed: 1991-01-30
Abstract: A method for producing inverse vertical seismic profile using a seismic source place down a borehole has been invented.  The directly transmitted waves from the seismic source and the secondary reflectances thereof are detected by a sensor(s) on the earth's surface.  The method depends only on knowing the relative arrival times at the sensor of the direct waves and the secondary reflectance waves.  A pseudo-reflection seismogram is produced by 1) Autocorrelating a recording of a long series of random pulses, such as those produced by a drill bit, to produce a one-sided autocorrelation function containing peaks corresponding to the direct waves, primary and secondary reflectances;  2) Stacking (adding the amplitudes for equivalent time points) a plurality of autocorrelation functions obtained at a single depth in the borehole to reduce noise; 3) Producing a series of stacked one-sided autocorrelation functions for different depths in the borehole to yield an IVSP; and 4) Vertically stacking together the one-sided autocorrelation functions from the series of recordings to remove peaks due to primary reflectances. The invented method also provides means to derive the interval velocities for individual geologic strata and to determine the position of the source relative to the IVSP and to a geologic horizon.  The IVSP, source positions, and interval velocities can be determined at the well site in approximately real time.  A single, one-component seismic sensor is sufficient for the recordings required to produce the IVSP.  Either polycrystalline diamond bits or tricone bits may be used as seismic sources.  However, the method is not limited to continuous randomly generated seismic sources and may also be used with periodic or impulsive sources.

Abstract: A fluid transfer structure for a transmission has a tube disposed in a central bore of a shaft.  The shaft and the tube cooperate to provide a feed passage, central of the tube, and a substantially annular lube passage formed between the tube and the central bore. The tube and shaft have cooperating structures that provide proper alignment of the tube in the central bore.  A plurality of radial passages are formed in the shaft in communication with the central bore.  At least one of the radial passages is in communication with the feed passage which is sealed from fluid communication with the annular lube passage.  The remaining radial passages are in limited fluid communication with the annular lube passage.

Abstract: ABSTRACT     The present invention is intended particularly for use in sawmills in order to cut sharp-edged boards from side slabs.          Using opto-electronical structural elements, it is intended to construct a measurement system for long objects having diffusely reflecting surfaces and to do this in a simple manner, said measurement system requiring no additional space in order to make these measurements.  To this end, a plurality of beam sources are installed at a specific interval from each other, said interval growing larger from the reference point to the detector row, and parallel to the longitudinal axis of the object to be measured, outside the reference plane of the analysing detector row, so that, viewed from the detector row, a triangle is formed in its illumination plane.  The object to be measured is guided transversely to the plans of observation, whereupon measurement points of the particular shape at this point are recorded for each beam source.

Title: Papillotome/sphincterotome procedures and a wire guide specially suited therefor

IPC: A61B19/00
Filed: 1992-05-15
Abstract: ABSTRACT OF THE DISCLOSURE     Disclosed herein is an improved papillotome/sphincterotome procedure and a wire guide which is specially suited therefor.  The disclosed wire guide includes an outer insulative tube of extruded teflon material, an inner shaft of nitinol, and a platinum coil at its distal end.  The outer teflon tube has been extruded to have an internal dimension which is sized to loosely accommodate the inner shaft of nitinol with a cushion of air therebetween for additional insulative effect, and the platinum alloy coil is also loosely positioned within the teflon tubing.  The nitinol material in the inner shaft has a high electrical resistivity which inhibits the flow of current, and also has superelastic characteristics which enhance the maneuverability of the guide. The nitinol shaft is tapered at its distal end where it is attached to the platinum alloy coil, which is radiopaque, allowing the tip to be readily viewed under radioscopic observation.  The wire guide also has visual markings on its outer surface at 5 cm., 10 cm., 15 cm, whereby positioning can be verified endoscopically, and a marking 200 cm. from its distal end, whereby the general position of the guide relative to the endoscope can be determined by external visual observation.

Title: Process for treatment of wastewater containing inorganic ammonium salts
Inventor: LEHMANN RICHARD W
IPC: C02F1/58
Filed: 1992-06-03
Abstract: GAB\CJS\ZIM9222 ABSTRACT OF THE DISCLOSURE    A process for treating an aqueous wastewater containing ammonium compounds.  The process comprises the steps of preheating a liquid influent and introducing the preheated influent, an oxygen-containing gas and the wastewater into a reaction vessel for undergoing wet oxidation.  An oxidized effluent is then withdrawn from the reaction vessel, which includes a gas phase containing ammonia and carbon dioxide and a liquid phase containing the ammonium compounds.  The temperature of the effluent is then reduced to a temperature sufficient to condense a substantial portion of the ammonia into the liquid phase, and afterwards the remaining gas phase containing a substantial portion of the carbon dioxide is separated from the resulting liquid phase.  Either prior to or subsequent to the separation the pH of the liquid phase is adjusted to a level whereby a substantial portion of the ammonia remains in the liquid phase when the liquid phase is subsequently subjected to an elevated temperature above the boiling point of water and the water content of the pH-adjusted liquid phase is then reduced by evaporation.

Title: Orientation apparatus and method for disk shaped parts
Inventor: LICHT THOMAS A
IPC: B07C5/02
Filed: 1992-08-20
Abstract: ABSTRACT      A high speed orientation apparatus for disk-shaped objects includes upper and lower turntables operated to provide constant angular orientation of the disk-shaped objects.  An automatic supply means supplies disk-shaped objects to one of a plurality of disk receiving stations located on the upper turntable.  The upper turntable and the lower turntable, which also includes disk receiving stations, are attached to a rotating means such that the disk receiving stations of the lower table are directly underneath the disk receiving stations of the upper table and both the upper and lower turntables rotate at the same speed. The plurality of disk receiving stations include operable disk retention means for holding and releasing a disk-shaped object.  An inspection and control device adjacent to the upper turntable determines by inspection the angular orientation of each of the disk-shaped objects and controls each of the operable disk retention means so that the disk-shaped objects are rotated to a predetermined angular orientation by the upper turntable and transferred to the lower turntable.  The disk-receiving stations of the lower turntable are maintained at a constant angular orientation.
