Patent number: 5929568Abstract: An incandescent bulb luminance matching LED circuit for causing the luminance of an LED to match the luminance of an incandescent bulb is disclosed. The incandescent bulb luminance matching LED circuit includes an input port (26, 56 or 82), an output port (28, 58 or 98), one or more light emitting diodes (22, 24, . . . or 88, 90 . . .), and a voltage (20 or 89) and/or current (50 or 86) compensation block.

Patent number: 5915743Abstract: An under-dimensioned surface on metal tooling used in repetitive high temperature formation of parts is repaired by application of a metallic coating by use of a metal arc spray system. The under-dimensioned area is first roughened, and then is bordered by a raised template spaced a short distance above the surface of the tool by shims. Next the metal spray coating is applied, followed by machining of the metal coating to the proper dimensions of the tool.Type: GrantFiled: June 30, 1997Date of Patent: June 29, 1999Assignee: The Boeing CompanyInventor: Jay M.

Patent number: 5913711Abstract: The invention provides an apparatus and method for continuously delivering ice particulates at high velocity onto a substrate for treating the surface of the substrate. The apparatus includes a refrigerated curved surface that is brought into contact with water to form a thin, substantially uniform, ice sheet on the surface. This ice sheet is of such thickness as to contain stresses so that the sheet is predisposed to fracture into particulates. A doctor-knife is mounted to intercept a leading edge of the ice sheet and to fragment the ice sheet to produce ice particulates. These ice particulates enter into at least one ice-receiving tube that extends substantially along the length of the doctor-knife. Once in the tube, the ice particulates are fluidized by a constant flow of air and are carried into a hose for delivery through an ice-blasting nozzle under pressure.Type: GrantFiled: June 10, 1996Date of Patent: June 22, 1999Assignee: Universal Ice Blast, Inc.Inventor: Sam Visaisouk

Patent number: 5860686Abstract: A vehicle for providing adjustable occupant space has a fixed occupiable section defining a first interior space. The fixed occupiable section includes a number of ground engaging wheels and has a floor affixed to a number of walls. Also included is an expandable occupiable section moveably coupled to the fixed section which also has a floor fixed to at least one wall. The expandable section defines a second interior space intersecting the first interior space which is moveable relative to the first interior space to vary an amount of total living space defined by the fixed and expandable sections. A carriage for supporting the expandable section and selectively positioning it relative to the fixed section is included to adjust volume of the living space defined by both sections. This carriage includes at least one arm pivotably anchored to the first section which engages the expandable section in a load bearing relationship.Type: GrantFiled: September 24, 1996Date of Patent: January 19, 1999Assignee: Kwikee Products Co., Inc.Inventor: Robert L.

Patent number: 5809297Abstract: A computer-based system for allowing a user to create a relational database schema. The system allows a user to create a semantic object data model of the database schema. The semantic object data model is defined by one or more semantic objects, each of which includes one or more attributes that describe a characteristic of the semantic objects. The attributes are defined as being either simple value attributes that describe a single characteristic of the semantic object; group attributes that include one or more member attributes that collectively describe a characteristic of the semantic object; formula attributes that set forth a computation that describes a characteristic of a semantic object; or object link attributes that define a relationship between two or more semantic objects.Type: GrantFiled: August 9, 1996Date of Patent: September 15, 1998Assignee: Wall Data IncorporatedInventors: David M.

Patent number: 5794950Abstract: A skate (10) includes a boot (12) and wheels (28), secured to a frame (14), and a brake (16). The boot includes a base (18), a heel counter (20) and a pivotable cuff (22). The brake includes a brake housing (32) connected to the frame by lower arms (34) and to the base of the boot by upper arms (36). A brake pad (38) is secured to the lower end of the brake housing adjacent the wheels. A push rod (40) extends upwardly from a top end of the brake housing along the axis of the brake housing, and bears against a cuff tab (42) secured to the back of the cuff of the boot. Forward pivoting of the cuff of the boot during skating does not activate the brake, while rearward movement of the cuff causes the cuff tab to push down on the push rod (40), resulting in engagement of the brake pad with the ground. Displacement of the brake pad in response to movement of the cuff is amplified by a hydraulic master-slave piston arrangement contained within the brake housing.Type: GrantFiled: July 12, 1996Date of Patent: August 18, 1998Assignee: K-2 CorporationInventors: John E. Svensson, Dodd H. Grande, Hans D. Grande, Shin B. Min

Patent number: 5756090Abstract: Methods and compositions are disclosed for producing air-activated, i.e., oxygen (O.sub.2) activated, disinfectant-sterilent solutions. Solutions containing a haloperoxidase (i.e., a halide:hydrogen peroxide (H.sub.2 O.sub.2) oxidoreductase, such as myeloperoxidase, eosinophil peroxidase or lactoperoxidase) plus a halide or combination of halides (i.e., chloride, bromide and/or iodide), an oxidase (i.e., a substrate: O.sub.2 oxidoreductase) capable of generating H.sub.2 O.sub.2, and a substrate specific for that oxidase, are separately prepared under aerobic conditions, but all of the component solutions are made anaerobic prior to final combination and mixing. The anaerobic formulations are dispensed into containers capable of maintaining the anaerobic condition (e.g., pressurized canisters). Dispensing the solution at the time of use exposes the formulation to air (i.e., O.sub.2) which activates its disinfectant-sterilent properties. O.sub.2 is the rate limiting component for oxidase generation of H.sub.Type: GrantFiled: June 1, 1995Date of Patent: May 26, 1998Assignee: EOE, Inc.Inventor: Robert C. Allen

Patent number: 5737402Abstract: A pay phone coin release mechanism includes a base plate fixed inside the pay phone casing and having a pivot pin extending therefrom to rotatably supported thereon a driven link having two opposite arms of which one has a pin formed thereon and the other one rotatably supports thereon a coin release roller adapted to cooperate with a conventional coin receiving mechanism. The base plate also has a hole through which a shaft rotatably extends to drivingly engage a driving link. The driving link has an elongated slot into which the pin of the driven link extends and drivingly engages. The shaft of the driving link extends outside the pay phone casing and connected to a user-actuateable lever so that by actuating the lever, the driving link is rotated to drive, through the connection between the elongated slot and the pin, the driven link to rotate about the pivot.Type: GrantFiled: September 17, 1996Date of Patent: April 7, 1998Assignee: Karlin Telecomm CorporationInventors: Li-Te Cheng, Sung-Min Lin

Patent number: 5725680Abstract: A first method for cleaning and stripping a surface employs, a high pressure fluid blaster including a rotating nozzle which has a plurality of separate fluid jet orifices. The fluid jet orifices are geometrically configured such that rotation of the nozzle in a single direction, i.e. clockwise, results in the desired metal cleaning or stripping. The plurality of jets are divided into two or more sets, each set having at least one jet therein, with the jets in each set oriented at a different angle from the jets in the other sets. This configuration will produce tubular streams of fluid as the nozzle rotates such that the streams first converge, then intersect, and finally diverge. As the jet streams are applied to a surface after the streams have diverged, they score the surface with concentric circular grooves due to the force of the high pressure fluid.Type: GrantFiled: October 20, 1995Date of Patent: March 10, 1998Inventor: George J. Mathieus
