Title: Cooling and combustion airflow supply system for a gas range
Inventor: LARSEN CHRISTOPHER A
IPC: F24C15/00
Filed: 2003-03-14
Abstract: A range includes a cabinet, defined by at least a front, side, bottom, and top portions, as well as upper and lower oven cavities each having a respective gas burner assembly. At least one passageway is formed to create an airflow path enabling a portion of an ambient airflow introduced into the cabinet to reach the gas burner assemblies of the upper and lower oven cavities for combustion purposes, preferably through natural convection, while the remaining portion of the airflow passes over and cools portions of the range. In a preferred form of the invention, insulation is maintained in a desired position below a respective oven cavity by a holder through which the airflow passes to the burner assembly.

Title: Metal alloy compositions and process
Inventor: DE FIGUEREDO ANACLETO M
IPC: B22D27/04
Filed: 2001-09-17
Abstract: A skinless metal alloy composition free of entrapped gas and comprising primary solid discrete degenerate dendrites homogenously dispersed within a secondary phase is formed by process wherein the metal alloy is heated in a vessel to render it a liquid (10). The liquid is then rapidly cooled while vigorously agitating it (12) under conditions to avoid entrapment of gas while forming solid nuclei (14) homogenously distributed in the liquid. Agitation then is ceased when the liquid contains a small fraction solid or the liquid-solid alloy is removed from the source of agitation (12) while cooling is continued to form the primary solid discrete degenerate dendrites in liquid secondary phase. The solid-liquid mixture then can be formed such as by casting.

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. The values of the surface parameters are then evolved using an appropriate evolution function. A volatility value for a particular option is extracted from the volatility surface defined by the evolved surface parameter values. The extracted volatility value can then be used in an option pricing model to provide a price of the particular option. The volatility of a basket options valued relative to the performance of multiple components can be simulated by determining the value of surface parameters for options on the component securities and then combining the component surface parameters to determine surface parameters for a volatility surface of the basket.

The reaction inhibiting layer may also contain a solvent, such as any transparent, non-absorbing solvent. Glycerol is one suitable example. The reaction inhibiting layer could also comprise water that evaporates to the environment. Also disclosed is an optically readable media that includes means for rendering the optically readable media unreadable, and that further includes an inhibit layer that contains a first substance that slows the passage of the second substance through the inhibit layer while the first substance is present in the inhibit layer. The second substrate is one involved in a chemical reaction that results in the optically readable media becoming unreadable.

The wind turbine can be mounted on a lattice tower, a monopole tower or a hybrid tower.      The wind turbine has either a fixed horizontal axis or a variable (but non-vertical) axis. Alternatively, a vertical-axis wind turbine may be used provided the generator is mounted at or near the top of the tower.
