Filed:

Apr 13, 2006

Appl. No.:

11/403616

Inventors:

Gerald Davis - Houston TX, US

Assignee:

LSI Graphic Solutions plus - Houston TX

International Classification:

F21S 8/00

US Classification:

362147000, 362294000

Abstract:

This invention is a lighting fixture to project even illumination onto flat panels. The fixture is a formed specular aluminum reflector with LEDs mounted to provide even and directed light, with modular connectors and power sources, allowing for variable lengths when combined with field adjustable housings and supports; or when mounted in a fixed length housing, to allow for linear lighting using any number of selectable lengths. This invention provides a pre-determined and directed light pattern requiring no field adjustment. The use of long life, weather resistant light emitting diodes provides for low maintenance and low energy consumption. The use of specular aluminum allows up to 95% of the light to be reflected to the surface, as well as provides heat sink properties further prolonging the life of the LEDs. By focusing all the available light on the desired area and eliminating stray light, lower wattage LEDs can be used.

US Classification:

427377, 427440

Abstract:

Water-borne amine-based preservative-impregnated wood is post-treated by: (a) contacting the preservative-impregnated wood in a closed vessel with live steam; (b) collecting a water-containing condensate generated in the vessel; and (c) recovering the post-treated wood from the vessel.

International Classification:

F25B 1300
F25B 4700
F25B 4300

US Classification:

62160

Abstract:

An integrated controls assembly for controlling fluid flow between first and second heat exchangers and a compressor in a heat pump, air conditioner, or like system. The integrated controls assembly includes an accumulator in the form of a tank communicating by conduits with the discharge outlet and the suction inlet of the compressor. The conduit leading from the discharge outlet includes a coiled section contained within the accumulator and leading to a reversing valve assembly, also contained within the accumulator. The reversing valve selectively directs the gas flow from the discharge outlet to one or the other of a pair of conduits leading to the heat exchangers and simultaneously directs the flow from the other heat exchanger to the interior of the accumulator and therefrom to the suction inlet of the compressor. Shifting of the reversing valve will reverse the flow of refrigerant through the heat exchangers. A bypass valve located at the reversing valve is provided to divert flow from the compressor to the interior of the accumulator in response to a drop in temperature inside the accumulator when refrigerant is flowing to the first heat exchanger from the compressor, and the second heat exchanger, thereby providing a higher evaporating temperature in the second heat exchanger to effectuate the removal of accumulated frost therefrom.

Assignee:

Sundstrand Corporation - Rockford IL

International Classification:

F16K 3104
F16K 3152

US Classification:

13762529

Abstract:

A reversing valve for use in air conditioning systems and the like for controlling the flow of fluid between a plurality of ports, the valve including a valve body with a chamber communicating with each of the ports, and a valve member mounted in the chamber for movement between two positions to control the flow. Means for moving the valve member are located to one side and generally centrally of the valve member, and include a reciprocable operating plunger engaging a grooved ramp in the valve member which forms a cam. A spring is provided at one end of the valve member to urge the valve member to one position as the plunger is retracted.

International Classification:

B01D 306
B01D 334

US Classification:

203 37

Abstract:

A process for treating naphthenic fractions with a caustic blend of sodium and potassium hydroxide, preflashing the naphthenic fraction to remove water and then flashing the dewatered fraction to remove the neutral oils and the materials that were not formed into the acid salts. The naphthenic salt mixture is then quenched and acidified so as to recover the naphthenic acids. Naphthenic acids recovered from the process of the present invention have acid numbers which are generally higher than the naphthenic acids heretofore produced from the corresponding feed streams. The process provides for the flashing of the water which otherwise would cause foaming and not permit the recovery of the acid salt for the enhanced separation of the naphthenic acids.

F21V 5/04

Abstract:

A disclosed downlight eyebrow includes an elongated L-shaped structure including a first wall and a second wall that may form an angle of approximately 90 degrees. The downlight eyebrow may be installed at or in proximity to an upper edge of a wall, fascia, or other type of vertical structure with the first wall of the eyebrow extending horizontally away from an upper edge of the vertical structure. In this configuration, the second wall of the downlight eyebrow may be oriented in a vertical or substantially vertical plane, extending downward from the first wall, parallel or substantially parallel with the illuminated region and displace from the illuminated region by a width of the first wall. In some embodiments, a reflective material, film, or coating may be disposed on an interior surface of the second wall of the downlight eyebrow, wherein the interior surface of the second wall functions as the primary reflector. The secondary reflector may be implemented as a flange that extends from an intermediate point in the eyebrow, downward and away from the second wall, toward the vertical surface. In other embodiments, the secondary reflector may be implemented as an elongated and winged or angled mounting structure referred to herein as a winged rail. In at least some embodiments, the winged rail includes a mounting wing and a reflective wing that form an obtuse angle, referred to herein as the wing angle. The LED string may be affixed to an inward surface of the mounting wing.
