Title: U-bolt bending apparatus
Inventor: GRAY JOHN C
IPC: B21D7/022
Filed: 1995-08-25
Abstract: A vertical frame supports an interchangeable mandrel or die which receives the center portion of an elongated metal rod having opposite threaded end portions, and the rod is clamped to the die by a pivotal locking bar secured by a wedge actuated by a hydraulic cylinder. The frame also includes a vertical plate having upper and lower corner blocks connected by a pair of vertical guide rods. The rods support a horizontal carriage cross bar for vertical movement, and the cross bar pivotally supports upper end portions of a pair of arms each formed by rigidly connected parallel spaced plates having aligned straight cam slots. A pair of bending rollers are supported by the lower end portions of the arms, and a hub member extends between the plates of each arm and supports slide blocks which wave within the cam slots. A hydraulic cylinder moves the cross bar vertically to move the arms and bending rollers along converging paths for overbending the rod around the die.      An elongated adjustment screw is rotatably supported by the lower corner blocks and a center block and extends between the plates forming the arms. The screw has appositely threaded portions engaging the hub members to provide for conveniently and precisely adjusting the spacing between the bending rollers for accommodating dies and rods of different sizes and shapes.

IPC: E21B10/02
Filed: 1995-10-06
Abstract: The drill body (3) carries one or more cutters (4) of radial width (R), with tapering relief rearward (K), and having both radial and axial projection from the body. The rearward taper terminates in a novel reduced step (S) which improves the long-term cutting and wearing characteristics. The maximum axial projection (B) of the free end of the cutter from the step, is 0.3-0.5 times the total axial length of the cutter. The step is located close to the tip of the body, at the cutting end. The projecting radial width of the cutter reduces by 30% at the step, on both sides of the cutter. The body may be a core drill, in which the radial cutter width, at first tapering rearward, is then similarly step-reduced into the inner and outer contours of the body.

Abstract: Présentement, il n'existe pas de gabarit permettant de tracer des pictogrammes avec rapidité et précision. Dans la présente invention, le gabarit est doté d'une fente en forme de "L" dans laquelle on peut y glisser un crayon. Cette fente permet de tracer les axes d'ordonnées et d'abcisses nécessaires à la construction d'un pictogramme. De plus, le gabarit comporte plusieurs rangées de carrés et de cercles gradués qui s'alternent. Ainsi par ces deux formes ont peut donc illustrer deux variables dans un pictogramme. De ce fait, si on attribue aux carrés du pictogramme la variable "automobiles X vendues mensuellement" et aux cercles la variable "automobiles Y vendues mensuellement", on peut tracer un pictogramme illustrant le nombre d'automobiles de chaque marque vendue sur une base annuelle. En attribuant par exemple à chaque carré et à chaque cercle une valeur de 10 000 voitures vendues mensuellement, on profite du fait qu'ils soient gradues en dix unités pour ramener le précision du pictogramme dans ce cas-ci à 1000 voitures par unité.

Patent CA-2166397-A1 (CA)
Inventor: WEININGER DAVID
IPC: G06F17/50
Filed: 1994-06-29
Abstract: A method of and apparatus are disclosed for evolving successive populations of molecular structures and evaluating each evolved structure of each population with desired physical and/or theoretical properties. An initial population of molecules is provided in terms of representations of a number of member molecules. Evaluation is performed by a fitness function, which compares the initial population and evolved generations of member representations with the set of desired properties to provide a numerical measure or value of fitness for each structure. That numerical value indicates how closely the compared member representation corresponds with the set of desired properties. The next population is generated by changing the structure of selected molecules of a population dependent upon the numerical measure of fitness, and the process repeats. Subsequent populations evolve towards ever-better fitness. The process is terminated when an acceptable molecule evolves.

Title: Process for Disposal of Decomposable Organic Waste
Inventor: VORONEY R PAUL
IPC: C05F9/04
Filed: 1996-01-25
Abstract: A process for disposal of organic waste containing large quantities of fat or oil. A sample of the waste is decomposed in soil containingample quantities of nutrients required for decomposi tion, specifically nitrogen and phosphorus. Resulting test data indicates how much nutrient material is required for decomposition, and how much, and when, nutrient material is released to the soil after decomposition. The waste is then incorporated into soil in a field, and nutrients are applied to induce a rapid decomposition phase in which soil organisms absorb and immobilize the applied nutrients to decompose the waste and a subsequent mineralization phase in which the soil organisms release nutrients to the soil. A crop is appropriately selected and planted to begin absorbing significant quantities of soil available nutrients during the mineralization phase. The amount of applied nutrient material corresponds to crop growth requirements plus waste decomposition requirements less nutrients released during the mineralization phase, effectively reducing nutrient requirements is for rapid waste decomposition. Soil organisms and crop growth tend to immobilize soil available nutrients through the process, and no soil available nutrients remain after completion of the process. Leaching of nutrients to groundwater is minimized.

IPC: H02K3/28
Filed: 1996-02-14
Abstract: A winding structure for an electric motor which permits a two phase electric motor to be operated from a three phase source of electrical energy is disclosed.  The first phase includes a first set of windings which are provided on a first set of stator poles and which are connected to a first current generating circuit.  Thus, the first phase is energized solely by the output electrical current from the first current generating circuit.  The second phase includes a second set of windings which are provided on a second set of stator poles and which are connected to a second current generating circuit.  The second phase further includes a third set of windings which are provided on the same second set of stator poles with the second set of windings.  The third set of windings are connected to a third current generating circuit and are wound in opposite directions from the second set of windings.  Thus, the second phase is energized by the output electrical current from the second current generating circuit less the output electrical current from the third current generating circuit.  Thus, the input current signals for the two phases exhibit a 90° phase differential  which make them well suited for use in operating a two phase motor from a three phase source of electrical energy.

Title: Automatic inspection method for contactlessly measuring an offset of a central feature of an object
Inventor: CSIPKES ANDREI
IPC: G06T7/00
Filed: 1996-06-13
Abstract: An automatic inspection method contactlessly measures the offset of a feature ofan object from a theoretical ideal center of the object, and is particularly suited for measuring at an endface of an optical fiber termination the eccentricity of an optical fiber core relative to a theoretical ideal center of the termination. The core is extremely smaller (typically between about 50 and 500 times) in size than the termination boundary. An inspection system for implementing the novel inspection method has a feature imager, one or more boundary segment imagers but preferably four in number, and a machine vision system connected to the foregoing imagers. The feature imager is positioned to capture an image of the feature (e.g., fiber core endface), and the one or more boundary segment imagers are positioned to capture an image of a corresponding boundary segment of the object (e.g., termination endface). The machine vision system determines the offset, or eccentricity, based upon the feature image and the one or more boundary segment images.
