Patent CA-2169331-A1 (CA)
Title: Method of treating sewage sludge containing fibrous material
Inventor: LYNAM BART T
IPC: C05F7/00
Filed: 1996-02-12
Abstract: A method of converting industrial, domestic or other sludge, into a pelletized or granular fertilizer, as well as a sludge converter for practicing the method. The sludge is dewatered to form sludge cake solids which are dried in a dryer, and then sorted with a sorter into a sorted product comprising oversized, undersized, and standard sized product.  Oversized product containing fibrous material is reduced in size by grinding in a hammermill.  A portion of the sorted product is recycled for mixing and sizing in a mixer with the dewatered sludge cake solids.  To control dust and odors, cyclones and a condenser remove a substantial portion of the gaseous particulate matter and condensable gases from the converter, and any remaining noncondensates are burned in the heat source flame.  A waste oil burning heat source supplies heat energy to the dryer. The heat source exhaust gas by-products are filtered in a bag house using a conditioner additive, such as lime or sodium bicarbonate, which may be reclaimed and supplied to the standard sized product to serve as a pelletizing binder, to enhance the fertilizer nutrient value, or to enhance the fertilizer shelf life.

Patent CA-2177088-A1 (CA)
Title: Positive pressure release valve
Inventor: HEWITT DANIEL BRIAN
IPC: E21B21/10
Filed: 1996-05-22
Abstract: In the oil industry, positive displacement motors are attached to the bottom hole assembly(BHA) mechanism to provide additional power to the bit. The motor is turned through the hydraulic force of the drilling fluids that are circulated within the drill string. However, once the bottom hole assembly becomes blocked, fluid can no longer circulate through the bit and back to surface. Serious problems arise as a result of this loss in circulation . In severe situations, this condition makes it possible to break off and lose the drilling pipe in the well bore.     The need for a remotely activated release valve to restore circulation within the well is critical. The technical knowledge disclosed within this application relates to a mechanical device that is designed to release the fluid trapped inside the drilling pipe once the bottom hole assembly has become blocked, thereby restoring circulation..     The Positive Pressure Release Valve is activated through a increase in fluid pressure created by the surface pumps. Once a certain internal pipe pressure is achieved, the release valves are permanently released and circulation is restored within the pipe and well bore.     The drill pipe is now in a position to be removed with minimal interruption and damage.

Abstract: Procédé et dispositif destinés à déterminer les variations de poids d'articles semblables distincts mais enchevêtrés, provenant d'une pluralité de sources d'approvisionnement, d'une manière qui permette d'identifier la source à l'origine de la variation de poids des articles individuels. Dans ce but, des groupes d'articles composés de nombres inégaux mais prédéterminés d'articles provenant d'au moins deux des sources (20, 20a) sont assemblés dans des réceptacles (8), la proportion du nombre des articles provenant des sources respectives pour chacun de ces groupes d'articles étant variée de manière prédéterminée. Lorsque ces groupes d'articles sont pesés (28), et que ces poids sont rapportés aux différentes proportions connues du nombre des articles provenant des sources respectives dans les groupes individuels, il est possible de déterminer la source fournissant les articles n'ayant pas un poids standard. De cette façon, on peut surveiller les variations de poids survenant dans n'importe quel nombre de flux enchevêtrés d'articles, en pesant les groupes de nombres égaux de ces articles.

One end of the elbow rest is for receiving an elbow of a human being, or adjacent parts of an upper limb adjacent to the elbow. The other end of the elbow rest, is mounted and adjoining the belt. One of the ends of the strap is mounted to hold the belt, adjacent to one side of the elbow rest. The other end of the strap is mounted to hold the belt, adjacent to a side opposite the one side of the elbow rest. Thus the strap is for running from one of the ends holding the belt, for diagonally crossing up the back of that human being, running over the shoulder joining the other upper limb, and diagonally crossing down the thorax, to finally hold the belt, adjacent to a side opposite the one side of the elbow rest. With this harness, shooting is more reliable.

Patent CA-2190932-A1 (CA)
Title: Bidirectional disappearing plug
Inventor: SHY PERRY C
IPC: E21B23/04
Filed: 1996-11-21
Abstract: A bidirectional disappearing plug member and plug assembly is capable of blocking pressurized fluid flow from opposing axial directions in a flowbore. In a preferred embodiment, the plug member, which blocks flow through the flowbore, may be readily and at least partially dissolved through the application of at least one pressurization and depressurization within a tubing string above the plug assembly. Construction of the plug assembly permits the plug member to be conveniently emplaced in a fluid-filled wellbore by permitting fluid flow around the plug member during the emplacement process. The plug member may then be secured within the plug assembly to block fluid flow from either axial direction. Operation of a plug rupture sleeve or mandrel, for at least partially dissolving the plug member, may be controlled by a ratchet assembly or linear indexing apparatus requiring multiple pressurizations and depressurizations before the plug member is exposed to wellbore fluids and thereby at least partially dissolved.

Title: Forensic sampling of ambient air by automatic forensic sampler
Inventor: GRANT MARK ANDREW
IPC: G01N1/22
Filed: 1996-12-31
Abstract: The present invention relates to an automatic sampler for air adjacent to the sampler, or its inlet port, which will either analyze the sample, or protect the sample until it can be analyzed by forensic specialists, by use of an event detection module, a sample suction device, a filter and sample holding chamber, coordinating electrical devices, analytical mechanisms, and one or more heat protection mechanisms. Only materials availableafter a fire are now sampled for forensic analysis; this severely limits the possible inferences.

Patent CA-2195111-A1 (CA)
Inventor: REED IRVING S
IPC: H03M7/30
Filed: 1995-07-14
Abstract: A computationally fast, effective method for compressing digital images uses an optimized subsampling process. A set of spatially overlapping spline functions (1014) is used as a basis onto which the image data (1012) are projected by use of a least-mean-squares criterion. The specified processes can be implemented for compressing and interpolating digital data arrays of N  dimensions. Linear, planar and hyperplanar spline functions allow convenient, fast and efficient closed-form optimal compression, which process is easily incorporated into existing digital processing systems. A key advantage of the disclosed method is the fast coding/reconstruction speed, because it involves only FFT or convolution types of processors.

IPC: C23C2/00
Filed: 1995-07-26
Abstract: A hot dip coating pot (2) having a strip inlet passage (3) and electro-magnetic plugging means to prevent leakage of bath liquid from the pot through that passage, wherein: the plugging means comprises two magnetic field generators (7) disposed one on each side of the passage; each generator projects an oscillating magnetic field into the passage from at least two poles of opposite polarity that are adjacent the passage and spaced apart in the through direction of the passage; the said at least two poles of each generator are respectively in substantial alignment with the corresponding poles of the other in the transverse direction of the passage; the magnetic fields projected by the generators have flux patterns which are substantially mirror images with reference to a plane of reflection coinciding with a centre plane of the passage; and both generators operate at a frequency of more than seven kiloHertz. When no strip is present the fields combine and extend transversely of the passage. When a strip is present the fields not only plug the passage but also provide restraining forces to prevent deviation of the strip from its intended pass line.
