Patent CA-2184327-C (CA)
Inventor: LAURSEN POUL
IPC: G01N27/90
Filed: 1996-08-28
Granted: 2005-01-04
Abstract: An apparatus for analyzing anomalies such as cracks, corrosion and the like in a pipeline wall is provided. The apparatus is formed of one or more cylindrical body sections. A series of magnetizing units are mounted around the circumference of the body.  Each magnetizing unit is formed by a backing bar, brushes which are capable of inducing a magnetic field, sensors which are capable of measuring magnetic flux leakage caused by anomalies in the wall and bearing wheels which reduce wear on the brushes and sensors. The backing bar is flexibly mounted on the body so that it can follow the contour of the pipeline wall as the apparatus moves through the pipeline. The backing bar has steel-containing brushes mounted on either end atop magnets of opposite polarities such that a magnetic field may be transmitted to the pipeline wall. The brushes are ideally formed by steel cables encased in polyurethane and mounted on a steel shell. The sensors are mounted in the central part of the backing bar, between the brushes. The sensors preferably have a parallelogram cross-sectional shape and are molded of polyurethane or other suitable material so that they are flexible enough to follow the contour of the pipeline wall as the apparatus travels through the pipeline and, hence, maintain the orientation of the sensing element in the sensor body in relation to the pipeline wall. A wear plate and wear pads may be mounted on top of the sensor body for reducing wear on the sensor.

Abstract: Quick boiling or instant cooking noodles such as udon, soba and hiyamugi or pastas such as spaghetti or macaroni can be produced by a process comprising the steps of heating dry noodles or pastas with either wet or dry heat for a short time to modify only the surface layer portion of the noodles or pastas, removing the surface moisture if the heating is done by wet heat, subsequently contacting the noodle or pasta strings with water to have it absorbed, and reheating the noodles or pastas if the final product is of an instant cooking type. The noodles or pastas thus produced can be prepared by merely boiling them for a short time or by simply pouring in hot water and letting stand for a short time or by dust cooking them in a microwave oven; the thus prepared noodles or pastas have the same texture as is obtained by fully boiling dry or raw noodles or pastas.

Granted: 2006-05-09
Abstract: A collapsible container liner for use within a bulk container having a substantially rigid top, bottom and side walls and a filler opening in the top wall. The liner is a collapsible bag of a flexible material with top, bottom and sides which correspond to the container walls within the interior of the container. A first opening in the liner top corresponds to the filler opening in the container top wall. A seal is formed between the container top wall and the liner top around the periphery of the filler opening and the first opening.  Optionally, the container bottom wall can be formed with a discharge outlet lined by a complementarily shaped liner discharge spout sealed adjacent thereto. A second opening in the liner top is spaced from the first opening and has an evacuation outlet attached to the liner top around the periphery of the second opening. Air is withdrawn through the evacuation outlet from the space between the liner and the interior of the container, a vacuum forms which collapses the liner against the container interior surfaces. A removable cap is sealably received in the evacuation outlet to maintain the evacuated condition within the space so that the liner retains its shape conforming to the interior configuration of the container.

Title: Detecting possible fraudulent communications usage
Inventor: EADEN RUSSEL
IPC: H04M3/42
Filed: 1996-03-29
Granted: 2001-01-23
Abstract: A method of, and a system for, detecting possible fraudulent use of a telecommunications network. Call event records, both call initiation and call completion records, are examined. A call record has a number of key fields, e.g. called number, calling number, calling card number, and for each field in turn the key is used to access a database containing an associated set of profiles. Each profile contains an algorithm defining a measurement process to be performed on the call data, e.g. determine the call duration. The respective process results are added to a respective set of stores associated with each profile, and an alarm response is generated when a threshold of a store is reached. An additional process for e.g. a call duration of e.g.  called number card calling number key fields, convert the process results to penalty points which are added to a penalty points store associated with the calling card number key of the call event record under examination. Each response is recorded in a history file for that key.

Abstract: A ceiling ventilation inlet (10) includes a housing having an air inlet aperture (14), an air outlet aperture (16), and a baffle (20) supported for linear movement adjacent the air outlet aperture (16). A spring (50) is positioned such that the baffle (20) moves dependant upon air pressure difference between the confinement space and the external environment. Air entering the housing opens the baffle (20) and enters the livestock confinement building in a 360 degree dispersion pattern. The spring (50) causes the baffle (20) to direct the flow of air into the confinement space at a near constant rate so as to optimize ventilation. The greater the air pressure difference between the confinement space and the external environment, the greater the air outlet area becomes. Since the inlet (10) is responsive to the pressure difference and the air outlet area increases or decreases in size, the airflow velocity entering the confinement space may be optimized at a near constant rate. Mathematical equations and limiting parameters define the relationship between the geometrical design of the ceiling ventilation inlet and the optimum and acceptable range of properties for the spring (50).

Abstract: The case has a molded plastic card member, and a lid specifically configured to mate with the card member to define an enclosed area. The lid is connected to the card member by a hinge adjacent one edge thereof so as to be foldable between an open position away from the card member, and a closed position against the card member to define the enclosed area. The card member and the lid preferably each have tabs extending from side edges opposite the hinge, each tab having a hole generally alignable with a corresponding hole in the other tab, for the installing of a closure such as a thick plastic loop not generally severable without a tool. The card member and lid define between them a number of openings through the enclosed area particularly sized for portions of tool components and/or extra tool components to extend therethrough generally parallel to the card member, for visibility and preferably manipulation, without it beingpossible to remove them as long as the case is closed. At least one of the enclosed area and an area of the card member outside the enclosed area have tool components and/or extra tool components receivers configured such that removal of a tool component and/or extra tool components through the openings from the enclosed area is prevented when the lid is in the closed position, by a wall of a recess, or by a raised stop or the like.

Abstract: A test sample card is provided with a locking feature for achieving a positive, locking engagement with a transfer tube that conducts fluid into the interior of the test sample card. The locking feature consists of a tubular channel inwardly disposed from the fluid intake port that has an inner annular rim defining a restriction. The annular rim is of a reduced diameter relative to the diameter of the transfer tube. A recessed region is positioned inwardly from the restriction that has an opening in one of the surfaces of the card body. When the transfer tube is inserted into the tubular channel, the first end is forced past the restriction into the recessed region, with the annular rim compressing the transfer tube. The user is able to sense with their hands when the first end is inserted past the restriction. Visual observation of the first end of the transfer tube through the opening in the card surface confirms that the transfer tube has been properly inserted into the test sample card.
