Appl. No.:

12/266657

International Classification:

G06Q 40/00

US Classification:

705 4

Abstract:

Drunk driving causes terrible misery. A new type of auto insurance called SoberTeen™ Driving insurance may help that. SoberTeen driving insurance is auto insurance that provides a 10% to 30% discount to young drivers who always drive sober and are willing to let an insurance company monitor their cars to verify it. Intoxication can be determined from measuring braking force, accelerator use and proximity to nearby cars. A “nonintrusive load monitor” algorithm can figure out if a driver is intoxicated, even if different drivers use the car. The insurance product may be set up so that the policy premium is based on monitoring a young driver during a one month probationary period, but there is no actual monitoring during the next year of insurance coverage. That way, driver privacy is protected.

Assignee:

Praxair Technology, Inc. - Danbury CT

International Classification:

F27B 700
F24F 900

US Classification:

432 64

Abstract:

An apparatus and method for providing a selected atmosphere at and within an opening to the interior volume of a furnace. Two or more paralleled diffusers adjacent to the furnace opening laminarly emit different fluids and provide a multi-layer fluid curtain over the opening. The curtain has a composite modified Froude number from 0. 05 to 10, and a thickness at emission of at least 5% of its extent in the flow direction. Partially covering the outside of the curtain is an optional, substantially flat, outer shield with an aperture coinciding with the furnace opening, which reduces the necessary flow rates of fluids. Optional side shields around the sides of the curtain also reduce the necessary fluid flow. A preferred diffuser comprises a porous tube in a housing with an outlet directed to emit fluid across the furnace opening. The outlet is covered with a screen to disperse the fluid flow and to protect the porous tube.

Inventors:

Mark S. Nowotarski - Ossining NY

Assignee:

Union Carbide Corporation - Danbury CT

International Classification:

F24F 900

US Classification:

98 36

Abstract:

A method and apparatus for reducing the amount of an external fluid which travels through an opening into an enclosed area. Also, a method and apparatus for protecting a surface area or plane from contact with or intermixing with an external fluid. The method, in general, comprises causing a fluid to flow, in laminar form, in proximity to or directly across an opening, a surface or an area plane to be protected. The depth or thickness of the flowing laminar fluid layer at its source of origin is at least about 0. 05 times the distance across the opening, surface area or plane to be protected, in the principal direction of flow of the fluid at its source of origin. The width of fluid flow at its source of origin and transverse the direction of fluid flow is at least about as great as the maximum width of the opening, surface or area plane to be protected, transverse the direction of fluid flow. The Force Number of the fluid must range between about 0. 05 and about 50; the preferred range for the Force Number is from about 0.

International Classification:

F27B 904
F27D 706

US Classification:

137 3

Abstract:

The present invention provides a method and apparatus for controlling the fluid flow bias of continuous, multiple zone processes having gas or vapor comprising atmospheres that are in immediate access to each other. Active control of the fluid flow bias in at least one process zone or control of the overall process fluid flow bias is achieved by applying force to at least one of the zones of the process in a manner which enables such control. A physical or chemical property or a change thereof in at least one process atmosphere is monitored and an appropriate amount of force is applied in response to the monitored property. The monitored property is related to the furnace flow bias by an algorithm, so that the flow bias can be controlled by controlling the at least one chemical or physical property monitored.

International Classification:

B23K 3538

US Classification:

228219

Abstract:

This invention relates to a method of conducting a joining/coating operation which provides good wetting of metal-comprising substrate surfaces by metal-comprising filler/coating materials while reducing the rate of metal oxide formation. The joining/coating operation is carried out in a controlled oxidizing atmosphere having an oxidation capability greater than that required to oxidize a metal-comprising filler material used for joining or a metal-comprising coating, but having less oxidation capability than that of air. Typically the controlled oxidizing atmosphere consists essentially of nitrogen and oxygen, wherein the oxygen concentration is controlled at a set point. The range of the setpoint corresponds with an oxygen concentration which can range from greater than about 10 ppm to about 100,000 ppm, depending on the application. When a flux is used and the joining technique is reflow soldering, the setpoint for oxygen concentration can range from greater than about 100 ppm to less than about 50,000 ppm of oxygen, depending on the application, with a preferred range from about 500 ppm to about 10,000 ppm. When a flux is used and the joining technique is wave soldering, the setpoint for oxygen concentration can range from about 1,000 ppm to about 100,000 ppm of oxygen depending on the application, with a preferred range from about 10,000 ppm to about 20,000 ppm.

US Classification:

Abstract:

An apparatus and method for processing a workpiece in an ambient-free, atmosphere of selected gas. A preparation vessel has an opening for entry of the workpiece and a diffuser oriented to emit across the vessel opening a laminar curtain flow of the selected gas which enters, purges the vessel and prevents the infiltration of air. The workpiece on its carrier is transported into the preparation vessel where air is purged out and replaced with selected gas. A processing vessel has a similar workpiece entry opening and diffuser. The preparation vessel and the processing openings are brought into coincidence, and the carrier is transported into the processing vessel for processing of the workpiece in the atmosphere of selected gas provided by the processing vessel diffuser.

International Classification:

US Classification:

219 74

Abstract:

A weld shield apparatus provides an atmosphere of inert gas within a conduit in an underbead region where an external weld joint is to be produced. The weld shield apparatus includes a diffuser structure having a convex exterior surface that is defined by a wall structure, the convex exterior surface is shaped to fit within the conduit and to be separated from an inner wall of the conduit by a clearance space. The diffuser wall structure is comprised of a porous material which enables gas communication between an inlet to the diffuser and the convex exterior surface. A seal is positioned immediately upstream from the diffuser structure and is positioned to engage the inner walls of the conduit so as to prevent the passage of gas in an upstream direction. A source of gas is coupled to the inlet to the diffuser structure and enables inert gas to pass through the porous material and to flow in a laminar manner, via the clearance space, past the underbead region and into the downstream region of the conduit. The resulting laminar flow and use of a neutral density gas enable small amounts of gas to be employed as a weld shield.
