Patent CA-1276468-C (CA)
Title: Apparatus and method for grinding sidewall areas of tires
Inventor: STRAND JOHN
IPC: B24B7/20
Filed: 1987-07-08
Granted: 1990-11-20
Abstract: ABSTRACT OF THE DISCLOSURE             A grinder for removing a predetermined amount of rubber at a predetermined angle from a raised or recessed area on the sidewall of an inflated tire as the tire rotates.   A pair of spaced sensors engage the sidewall area of the tire at predetermined radial spaced locations on opposite sides of the area to be worked.  The sensors generate a pair of electrical signals in relationship to the profiles of the sidewall areas engaged thereby.  The signals are fed to a microprocessor which calculates the average angle of the raised or recessed area by the difference between the outputs from the two sensors along with the known spacing therebetween and generates a third signal.   This third signal is supplied to a servo mechanism which automatically adjusts the grind angle of the grinding wheel to match the average angle of the area to be ground.   A fourth signal is supplied by the microprocessor to another servo mechanism which dynamically controls the depth of grind of the grinding wheel in relationship to the profile of the sidewall represented by the signal generated by one of the sensors.   In an alternate embodiment the signal generated by the microprocessor representing the average angle of the area to be worked  controls the spacing between the tire beads by adjusting the tire mounting chuck to place the sidewall area in a relatively flat plane for perpendicular contact by the grinding wheel eliminating angle adjustment of the grinding wheel.

Title: Eliminating air and water from fuel in internal combustion engines
Inventor: NUNES ANTONIO J R R
IPC: F02M37/54
Filed: 1987-10-20
Granted: 1992-06-09
Abstract: An apparatus for detecting air and water in and eliminating air and water from the fuel in diesel-type internal combustion engines includes a main body which is composed of an upper part, a cylindrical and transparent intermediate part, and a lower base part. The upper part defines five openings of suitable diameter. The first opening is connected to a connection tube for taking in fuel from a fuel tank. The second opening receives a suction tube immersed in fuel contained in the intermediate part and in communication with an injection pump. The suction tubes defined an inlet hole at the lower level within the intermediate part which ensures that fuel is conducted to the injection pump without air. A third opening is in communication with a fuel return leakage of the injection pump. A fourth opening receives a warning probe member which includes a float sliding in a guide member. The float controls two magnetic switches by sliding in the guide. A fifth opening serves as an air outlet connected to an electromagnettic valve which, in turn, is connected to an automatic air discharge means controlled by the warning probe. The lower base body includes a means for removing water.

IPC: E21B43/263
Filed: 1987-11-10
Granted: 1992-03-24
Abstract: MMTR   EMH:DR:jw ABSTRACT OF THE DISCLOSURE          Subterranean  oil  and  gas  producing  formations  are fractured by filling a well casing with a compressible hydraulic fracturing fluid comprising a mixture of liquid, compressed gas, and propant material and precompressed to a pressure of about 1,000 psi or more greater than the fracture extension pressure at the  depth  of  the  zone  to  be  fractured.    A  perforator is provided in the casing to form fluid exit perforations at the selected depth of the fracture zone.   Following perforation the perforated  zone  is  fractured  by  the precompressed  fracturing fluid laden with propant material that is discharged into the formation until the hydraulic extension pressure is reached and the perforations are eventually sanded off.  Optionally, filling of the well bore is maintained continuously through the filling and perforation of the casing until after decompression of the fracturing fluid is completed.

Patent CA-1335862-C (CA)
Inventor: TOGNAZZO VALERIO
IPC: C10J/
Filed: 1988-05-30
Granted: 1995-06-13
Abstract: The  process  and  the  apparatus  are  for  the transformation of combustible pollutants or waste materials into  clean  energy  and  useful  products.    The  process comprises  the  steps of  submitting  the material to be treated to the action of a thermic lance in an airless atmosphere  so as to  totally decompose  it and  extract combustible gases, non-combustible gases and inerts.  Then the thermally decomposed products are cooled and the inert products  with  water  are  separated.    Steam  is  thus generated, which is introduced with the cooled gases onto a heated carbonaceous mass in order to filter the gases and, in part, transform them to obtain hydrogen, carbon monoxide  and other  totally  useful  gaseous  products. Finally, the gaseous products are cooled.

Granted: 1994-05-03
Abstract: Abstract of the Disclosure This invention is directed to a method for heat treating a sheet of a potentially photochromic glass to cause the growth of silver halide crystals therein which impart photochromic properties thereto, wherein the heat treated sheet will be essentially free from thermal deforma-tion and surface defects, and the photochromic properties exhibited therein will be essentially uniform across the area of the sheet.  The method involves first placing a sheet of potentially photochromic glass on top of a sheet of carrier glass that exhibits a softening point at least 50°C higher than the temperature at which the potentially photochromic glass will be heat treated, and thereafter subjecting the stacked sheets to the heat treatment tempera-ture desired for growing silver halide crystals in the glass.

Title: Adjustable bait-receiving fishing lure
Inventor: FRANCKLYN GILBERT W
IPC: A01K83/06
Filed: 1988-07-26
Granted: 1993-04-06
Abstract: ADJUSTABLE BAIT-RECEIVlNG FISHING LURE        Abstract of the Disclosure An adjustable bait-receiving fishing lure is disclosed for use in receiving baits of varying size and producing differing lure retrieval patterns.The bait-receiving lure includes a top section and bottom section that coopera-tively engage the upper and lower forward portions of a bait. A diving lip controls the depth at which the lure is retrieved and provides a swimming action. A screw, passing through disc-like portions of the top piece, bottom piece, and diving lip allows the relative orientation of these components to be adjustably secured. In this manner, baits of varying size can be accommodated between the top and bottom sections, while the diving lip is adjusted to producea desired lure retrieval pattern for the particular size of herring and trollingspeed involved. To adjust the lure's action, the line is attached to the diving lip by a removable and rotatable, frictionally secured plug. By changing the orientation of the plug with respect to the diving lip, the point of connection between the line and lure varies, allowing the lure to traverse a helical pattern underneath the surface of the water.

Title: Chewing gum containing zein coated high-potency sweetener and method
Inventor: ZIBELL STEVEN E
IPC: A23L27/00
Filed: 1988-11-18
Granted: 1995-02-28
Abstract: The present invention is a method for producing a chewing gum with a delayed release high-potency sweetener as well as the chewing gum so produced.  The delayed release high-potency sweetener is obtained by mixing a quantity of previously coated high-potency sweetener particles with a limited quantity of a solution of zein.  Preferably, the zein is dissolved in water with a pH between about 11.5 and about 12.1.  The quantity of the zein solution being added is limited to thereby produce a damp mix which is characterized as being dust free, non-flowing, and crumbly.  The damp mix is dried and then particle sized to thereby produce twice-coated particles of the high-potency sweetener within a predetermined particle size range.  When incorporated into the chewing gum, these particles are adapted to enhance the shelf-stability of the sweetener and/or produce a delayed release when the gum is chewed.
