Title: Tip heater cartridge and soldering iron for use therewith
Inventor: DUNHAM PAUL ALAN
IPC: B23K3/03
Filed: 2002-09-16
Abstract: A tip heater cartridge and a soldering iron with handpiece for use therewith in which, according to a preferred embodiment, a precision molded plastic sleeve is provided on the tip heater cartridge body. The sleeve is provided with an axially extending, radially projecting key which assures accurate tip-to-handpiece orientation and also produces a rigid mechanical interlock between the tip heater cartridge and the handpiece to ensure that there is no axial rotational or lateral movement or load transmitted from the tip of the tip heater cartridge to the electrical connector. In a particularly preferred arrangement, the end of the key acts with the handle keyway to prevent over insertion of the tip heater cartridge into the handpiece, which could damage the electrical connector assembly, and an O-ring on the electrical connector assembly acts to produces a seal relative to the body of the cartridge that prevents solder fumes from flowing into the connector assembly. The O-ring also serves to assist in retaining the cartridge within the handle and provides additional lateral support to the cartridge.

Patent CA-2407266-A1 (CA)
Inventor: JI CHEOL HO
IPC: H04Q11/04
Filed: 2001-11-23
Abstract: Disclosed relates to an asymmetric digital subscriber line (ADSL) access multiplexer connected direct to existing Ethernet and an ADSL network system using ASDL access multiplexer. The ADSL network system excludes a conventional network access server (NAS) and connects the ADSL access multiplexer direct to the Ethernet, thus decentralizing the processes for authentication, imposition of charge and traffic to a corresponding local network. Accordingly, the problem of traffic centralization raised by the conventional NAS is solved readily. Besides, the ADSL access multiplexer according to the invention further includes a remote authentication dial-in user service (RADIUS) client program, whereby the processes for authentication and imposition of charge are made very easily.

Title: Laminated distribution manifold plate system
Inventor: MCGUFFEY GRANT
IPC: B05C5/04
Filed: 2002-10-29
Abstract: A hot melt adhesive material flow control system comprises an input manifold for receiving a supply of adhes-ive material, a plurality of flow control valves from which the adhesive material is discharged, an output manifold for heating the adhesive material and conducting the hot melt adhesive material to the flow control valves, a pair of mul-tiple outlet pumps for supplying the adhesive material to the flow control valves, and a recirculation pump for re-circulating adhesive material back from the flow control valves to the pair of multiple outlet pumps. A distribution plate and a recirculation plate are interposed between the input and output manifolds and have separate and independent fluid circuits or flow paths defined upon opposite surfaces thereof. In this manner, the number of plates required to define the flow paths is significantly reduced. In addition, the output manifold, the flow control valves, the recircula-tion pump, and the multiple outlet pumps are independently mounted upon the input manifold so as to simply disassembly and reassembly of the components in connection with mainten-ance, cleaning, replacement, or repair operations.

Title: Method and system for stress testing simulations of the behaviour of financial instruments
Inventor: MAGHAKIAN ARTHUR
IPC: G06Q40/00
Filed: 2003-05-22
Abstract: A method and system for simulating changes in volatility for a price of a particular option on an underlying financial instrument is disclosed. A volatility surface model having at least one surface parameter is provided along with a set of volatilities for a plurality of options on the underlying financial instrument. The set of volatilities is analyzed to determine an initial value for each surface parameter which, when used in the surface model, defines a surface approximating the set of volatilities under normal market conditions. The values of the surface parameters are then evolved using an appropriate evolution function. Prior to applying the surface parameters to the model, the parameter values can be adjusted to introduce changes in offset, skew, term, or other parameters of the volatility surface to allow for simulation of unusual market conditions. A volatility value for a particular option is extracted from the volatility surface defined by the evolved and stress-adjusted surface parameter values.  The extracted volatility value can then be used in an option pricing model to provide a price of the particular option.

Abstract: A composite metal laminate coin planchet comprises commercially pure aluminum cladding layers metallurgically bonded to a zinc alloy core. The zinc alloy core may contain a hardening agent, such as copper or titanium, used to increase the hardness of the alloy above that of pure zinc. Trace amounts of other elements may also be present in the zinc alloy core or in the commercially pure aluminum cladding layers which do not affect their pertinent properties. The coin planchet is produced by a process comprising providing a strip or sheet of a zinc alloy core and creating a strip or sheet of composite material by metallurgically bonding commercially pure aluminum cladding layers to the zinc alloy. The coin planchets are then removed from the strip or sheet of composite material, and the remaining composite material is heated above its melting point to produce a zinc-aluminum alloy useful in die-casting.
