Device And Method For Measuring Heat Flux And Method For Forming Such A Device

US Patent:
4541728, Sep 17, 1985
Filed:
Jul 25, 1983
Appl. No.:
6/517202
Inventors:
Ray L. Hauser - Boulder CO
Rodney B. McKeever - Boulder CO
International Classification:
G01K 1700
US Classification:
374 29
Abstract:
A device and method are disclosed for measuring heat flux, as is a method for forming a device for such use. Thermopile junctions are formed on a belt-like support so that the heat flux from an article, such as a pipe or process equipment, is sensed while the support is positioned against a surface of the article, and a voltage indicative of the sensed heat flux is generated and coupled to an outlet connector adapted for connection to a voltage readout device. The belt-like support is relatively narrow, flexible, and has one side of a polymer with high infrared emissivity and the other side of a metal foil with low infrared emissivity. The support has mounted thereon a pair of thermopile elements each of which includes a non-metallic core having a high electrical resistance wire wound thereon, with a like portion of each turn of wire wound on the core having a low electrical resistance metallic plating thereon whereby heat flux through each thermopile element causes a temperature differential at opposite sides of the core which generates a thermoelectric current to thus provide a DC voltage that is coupled on the wound wire to an output connector at one end of the belt-like support. A second connector at the other end of the belt-like support has a bridging connector connected thereto during use for connecting the wound wires of a pair of thermopile elements, and the effective length of the device can be increased by connecting together a plurality of supports having thermopile elements mounted thereon through the connectors.

Hair Clip Having A Novel Gripping Mechanism And Removable Decorative Attachments

US Patent:
6082371, Jul 4, 2000
Filed:
Aug 26, 1999
Appl. No.:
9/383546
Inventors:
Rodney Brent McKeever - Boulder CO
Ray Louis Hauser - Boulder CO
International Classification:
A45D 804, A45D 812, A45D 800
US Classification:
132276
Abstract:
A hair clip includes a low profile clip mechanism which translates linear pressure on the ends of the clip into rotational action for opening the curved comb moldings. Springs cause the clip to close when pressure on the clip ends is removed. The barrel of the clip may comprise sections which are fixed with respect to the clip ends and sections which are attached to the comb moldings, and which are rotated by the clip mechanism. Or, the barrel may comprise alternating sections attached to each comb molding. Removable decorative attachments attach to the fixed portions of the barrel of the clip, via magnets, snap on grips, velcro. TM. or the like.
