Patent CA-2393497-A1 (CA)
Title: Plasma arc torch
Inventor: HORNER-RICHARDSON KEVIN D
IPC: H05H1/34
Filed: 2000-12-05
Abstract: A plasma arc torch has a cathode and electrode having connecting ends configured for a coaxial telescoping connection with one another on a central longitudinal axis of the torch. The connecting ends have interengageable detents thereon, with at least one of the detents being movable in a generally radial direction relative to the central longitudinal axis of the torch between an undeflected state and a deflected state. The at least one detent is movable from the undeflected state to the deflected state when the cathode and electrode are telescoped one into the other, and is movable from the deflected state back toward the undeflected state when the cathode and electrode are further telescoped to a point where the detents on the cathode and electrode are generally axially aligned. In this position, the at least one detent is engageable with the other detent to interconnect the cathode and electrode and inhibit axial movement of the electrode away from the cathode.

Title: Systems and methods for evaluating the appearance of a gemstone
Inventor: REINITZ ILENE M
IPC: G01N21/87
Filed: 2001-10-11
Abstract: Of the "four C's," cut has historically been the most complex to understand and assess. This application presents a three-dimensional mathematical model to study the interaction of light with a fully faceted, colorless, symmetrical round-brilliant-cut diamond. With this model, one can analyze how various appearance factors (brilliance, fire, and scintillation) depend on proportions. The model generates images and a numerical measurement of the optical efficiency of the round brilliant-called DCLR - which approximates overall fire. DCLR values change with variations in cut proportions, in particular crown angle, pavilion angle, table size, star facet length, culet size, and lower girdle facet length. The invention describes many combinations of proportions with equal or higher DCLR than "Ideal" cuts, and these DCLR  ratings may be balanced with other factors such as brilliance and scintillation to provide a cut grade for an existing diamond or a cut analysis for prospective cut of diamond rough.

Abstract: Method and apparatus for detection of the presence of a train wheel on a train track that overcomes problems associated with previously known detectors. The invention includes a method for detecting the presence of a train wheel on a train track. The method includes the steps of: a) generating an electromagnetic field using at least one electromagnetic field generator sensor including a resonance tank circuit; b) providing an electrical charge to the tank circuit when amplitude of the frequency drops below a predetermined level by using a charging circuit; c) providing a feed back from the tank circuit permitting the charging circuit to determine when the amplitude of the frequency has dropped below the predetermined level; d) holding the electromagnetic field generator proximate a train rail so that a train wheel causes a drop in the frequency amplitude below a second threshold level when a train wheel partially affects the field, and so that there frequency amplitude below a third threshold level below the second threshold level when the train wheel is located so that it fully affects the field; e) detecting when there is an increase in frequency amplitude above a first threshold level indicating that the electromagnetic field generator is no longer in a proper position relative to the train rail; f) detecting when there is a change in frequency amplitude relative to the threshold levels; and g) compensating for drift of frequency amplitude between the first and second threshold levels and ceasing such compensating when the frequency amplitude is above the first threshold level or below the second threshold level. The method includes all uses of the detector and apparatus as previously described. The invention further includes apparatus for practicing the method of the invention.

Title: Fenestration frame assemblies, e.g., retrofit window frame assemblies, and methods of installing same
Inventor: ENGEBRETSON DAVID
IPC: E06B1/04
Filed: 2003-05-28
Abstract: Assembling window frame assemblies often requires skilled labor at a construction site. Various aspects of the invention provide frame assemblies and methods of installing that may reduce the need of skilled carpenters on-site in some circumstances. In one particular example, the invention provides a window frame assembly that includes a cover, a main frame, and a glazing pane. The cover has a transverse member that includes a mating projection. The main frame has a window opening and a confronting periphery. The confronting periphery includes a peripheral recess and a guide, with the peripheral recess being sized to telescopically receive a portion of the cover mating projection. The guide may include an outwardly flared guide surface that is adapted to guide the leading edge of the mating projection into the recess. The presence of the guide can greatly facilitate assembly of the cover and the main frame in a window housing.

Title: Steerable antenna and receiver interface for broadcast
Inventor: SCARPA CARL
IPC: H01Q7/00
Filed: 2001-12-20
Abstract: Antennas with steerable antenna patterns and techniques for using such antennas are described. In accordance with the invention, antenna patterns with one or more NULLs are used. Through the use of digital control signals the antenna pattern is streered so that a source of signal interference, e.g., a multipath signal, will be located in a NULL. In this manner the received signal's S/N ratio can be maximized thereby facilitating demodulation. The techniques of the invention can be applied to television, computer devices, mobile devices and a wide range of other systems. Digital commands to control (304) an antenna may include multiple information fields, e.g., a direction field, a channel field, a gain field (410) and a polarity field. Antennas incapable of supporting the specified fields disregard information in fields which are not supported. Information in each supported field is decoded and used to adjust the corresponding antenna characteristic.
