Patent CA-2010100-A1 (CA)
IPC: G01R21/133
Filed: 1990-02-14
Abstract: A method and apparatus for measuring AC power, in which a measured digital value of an AC voltage is decomposed into two components with a phase difference of 90° therebetween, while a measured digital value of an AC current is decom-posed into two components with a phase difference of 90° therebetween, and a scalar product of a first vector consisting of the two components of the AC voltage and a second vector consisting of the two components of the AC current is calculat-ed.  The scalar product thus calculated represents active power carried by the AC current at the AC voltage.  Separately, absolute value of vector product of the first vector and the second vector may be calculated, which absolute value of the vector product represents reactive power carried by the AC current at the AC voltage.

Abstract: The process for joining bundled paper layers 13 is based on the injection of binder into the layers.  This binder injection 15 can consist of pressing binder into paper layers preperforated by needles 22, perforation either taking place beforehand or in the same operation by means of injection through hollow or tubular needles 22.  Another possibility of binder injection 15 involves the shooting in of binder droplets.  The after-treatment 16 of the paper layers can consist of pressing and/or ultrasonic action.  Optionally binder injection only takes place into the inner pages 52 of the paper layer 13 without the cover page 51 and middle page 53.

Abstract: ROOFING SYSTEM WITH INTEGRAL GUTTER                         ABSTRACT A roofing system for a sloped roof having a base with a generally horizontal top surface and a generally vertical edge has an internal gutter in its lower margin.  The system includes a first flashing, that is attached to the base, having a lip which projects from the top surface of the base.  The base is covered with sheets of flexible, thermally weldable roofing material with the top margin of each sheet being attached to the base and the bottom margin overlapping and welded to the adjoining sheet.  The lower margin of the lowest sheet overlies the lip of the first flashing to form the gutter.  A second flashing, which conformingly overlies the first flashing, is attached to the base over the sheet to clamp the margin of the sheet against the edge of the base.  The margin of the lowermost sheet is pulled progressively tauter over the lip of the first flashing at the sides of the roof than at the downspout to make the gutter slope downwardly towards the downspout.  A tack strip of the roofing material is attached to the roof base adjacent to the edge at an angle such that it is progressively further from the edge extending away from the downspout.  The lowermost sheet is thermally welded to the tack strip before it is pulled over the lip of the first flashing and the second flashing is installed, which causes it to automatically be biased to form the slope in the gutter.

Abstract: The present invention pertains to a fiducial implant for the human body that is detectable by an imaging system.          The invention is comprised of a first portion and a second portion.  The first portion is configured to be detected by an imaging system when place beneath the skin.  The second portion is configured for fixed attachment to a bone beneath the skin without penetrating entirely through the bone and without penetrating entirely through the bone and without fracturing the bone.  The first portion is sufficiently large and comprised of a material for detection by an imaging system, and sufficiently small to avoid the distortion of the skin when placed at an interface between the skin and the bone.  The first portion also has at least a portion which is spherical and defines a surface for cooperating with a tool for securing the second portion to the bone.  Additionally, the placement of an fiducial implants, where n4 and an integer, into a portion of anatomy of the human body allows for the recreation of a particular image slice of the portion of the anatomy taken by an imaging system with respect to a first time period, at subsequent imaging sessions and also with different scan modalities.  This provides a doctor with the ability to accurately follow the progress of the portion of the anatomy of interest.  Moreover, the existence of an fiducial implants allows a target to be identified within the portion of anatomy relative to an external coordinate system.  The portion of anatomy with the target may then be operated on, for instance, robotically, or precisely irradiated.

Abstract: A child resistant closure comprising an outer shell having a base wall and a peripheral skirt and an inner shell having a base wall and a peripheral skirt telescoped within the outer shell. The inner surface of the base wall of the outer shell and the outer surface of the base wall of the inner shell have circumferentially spaced radial projections which are adapted to interengage upon relative axial movement between the shells. The top wall of the inner shell includes indentations or grooves between the projections which are at a small acute angle with respect to the plane of the top wall of the inner shell. The inner surface of the outer shell has at least one inclined indentation or surface which extends radially and is also at an acute angle to the plane of the base wall of the outer shell. When the outer shell is tilted in the direction of the inclined surface, the lugs projecting from the area of the inclined surface of the base wall of the outer shell engage the grooves in the outer surface of the base wall of the inner shell allowing the inner shell to be unscrewed from the container on which the closure is provided. The closure can be also operated by moving the outer shell axially toward the inner shell to engage the projections on the outer shell and inner shell.

Abstract: ABSTRACT    A method and apparatus for the separation of viscous mixtures, comprising charging the mixture with solvent to form a dispersion before extraction to improve the extraction over a simple solvent extraction.  The mixture to be treated is charged with solvent before the extraction and is then sprayed into the extraction column where it is dispersed.       This treatment provides extraction of highly viscous, pasty materials.  The charging with solvent can take place until the mixture is saturated with the solvent, and favorable temperature and pressure conditions for charging may be provided in a charging column that is separate from the extraction column.
