Title: Dual alloy railroad wheel
Inventor: RUNKLE JOSEPH C
IPC: B60B17/00
Filed: 1998-10-07
Abstract: A railroad wheel formed from at least two metallic alloys. In one embodiment, a railroad wheel has a body formed from a first alloy and a rim formed from a second alloy initially in powder form. In an exemplary embodiment, to form the dual alloy wheel the body of the wheel is cast with a circumferential channel formed therein. The perimeter of the body is enveloped with a material, such as sheet metal, to form a cavity defined by the channel and the sheet metal. The second alloy in the form of a powder is placed in the cavity and subjected to heat and pressure to metallurgically weld the first and second alloys and form a composite railroad wheel.

Patent CA-2308664-A1 (CA)
Title: Linear actuator
Inventor: NEFF EDWARD A
IPC: H02K41/02
Filed: 2000-03-16
Abstract: A linear actuator includes a plurality of magnetic plates and a ferrite core with a conductive cover which are mounted on the actuator body to generate a permanent magnetic field. The linear actuator also includes a metal bobbin which has an outer surface and which is formed with an aperture that defines an inner surface for the bobbin. Further, the bobbin is formed with a gap which extends along its length and which intersects the bobbin from its inner to its outer surface. An insulating insert is placed in the gap. Finally, a winding is wrapped around the outer surface of the bobbin to form an electromagnetic coil, and the coil on the bobbin is slidingly mounted on the actuator to receive the ferrite core through the bobbin's aperture.  Electrical current can then be selectively applied to the winding to interact with the permanent magnetic field and thereby cause reciprocating motion of the coil. Due to the gap in the bobbin, an induced current which would otherwise hinder the desired reciprocating motion of the coil does not form on the outer surface of the bobbin. Due to the conductive cover, the response time of the coil to the applied current is reduced. In this manner, precise, high speed reciprocating motion in the linear actuator of the present invention is achieved.

Patent CA-2315463-A1 (CA)
Inventor: KRYCKI ROBERT D
IPC: B29C48/10
Filed: 2000-08-09
Abstract: An air ring, for supplying successive streams of cooling air to the exterior surface of a tubular bubble of plastic after its extrusion from an annular die, has a primary annular cooling air outlet arranged to be located around and closely adjacent the die orifice, and a secondary annular cooling air outlet located axially downstream of the primary annular air outlet in the direction of travel of the tubular bubble. The primary annular air outlet is formed between an inner lip and an adjacent edge of an intermediate lip, and the secondary annular air outlet is formed between an outer lip and an adjacent edge of the intermediate lip. The lower lip, intermediate lip, and the outer lip are arranged to diverge from the die so as to allow the tubular bubble to expand coaxially with the die at an angle of divergence of at least 60 degrees from the die axis without interfering with any of the lips. Air ring means is also provided for ease of adjustment of cooling air flow rate from the primary cooling outlet. Better control of the product is therefore made possible while permitting tubular bubble expansion with an angle of divergence of up to 60 degrees or more. Apparatus is also included to remove contaminants from a tubular bubble immediately after its extrusion.

Title: Credit risk estimation system and method
Inventor: NUDELMAN GREGORY
IPC: G06Q40/00
Filed: 2000-11-23
Abstract: A method creates an adjusted credit risk transition matrix and related matrices. The method uses the steps of obtaining a real probability measure (P) transition matrix, and adjusting the (P) transition matrix to be consistent with default probabilities under martingale measure (Q) by making the last column (default probabilities) in the (P) transition matrix consistent with default probabilities calculated under (Q). The method further scales the other entries in the transition matrix (P) to compensate for the adjustment while retaining the relative weights among non-default classes from the (P) transition matrix in the adjusted transition matrix. A credit risk model for the analysis of complex credit instrument implements the method. The adjusted transition matrix may be for use in analysing complex credit instruments. The model may be implemented in computer software on a computer readable medium. The adjusted transition matrix may be used to price credit swaps or value credit instruments. The model may have a simulation engine to generate valuation scenarios based on the adjusted transition matrix. The simulation engine may generate scenarios based on a Monte Carlo method. The model may be extended for the risk analysis of complex portfolios of credit instruments with stochastic interest and foreign exchange rates. The model may have a Monte Carlo simulation engine to generate valuation scenarios based on the joint distribution of interest rates, spreads, foreign exchange rates and obligors' credit migrations consistent with obtained or adjusted (P) transition matrix.
