Filed:

Jan 15, 2003

Appl. No.:

10/345571

Inventors:

David Eugene Weaver - Lookout WV, US
Richard E. Nash - Winston Salem NC, US
James W. Blake - Rainelle WV, US

International Classification:

F03B015/06

US Classification:

415 42, 415 44, 416111, 416119, 416132 B, 416169 R, 416153

Abstract:

A fluid drive conversion system having a plurality of flat foils rotatably connected to a vertical shaft such that the foils are generally vertical in position, pivot about a vertical axis, are a predefined distance, at least about one quarter of the width of a foil, from the vertical shaft thereby creating a central space. In operation, fluid flows through the central space and simultaneously pushes the back side of at least one foil while pushing the front side of one or more remaining foils, resulting in all of the foils rotating about the vertical shaft and contributing to the generation of usable energy. A wing is pivotally connected to the distal end of each radial arm and a bottom radial arm wherein each wing is in a general vertical orientation. The fluid drive conversion system employs either a conventional gear system, a conventional pulley system, or an electrical generation assembly using magnets, coils, and a means for harnessing an electrical current.

International Classification:

C23C 16/448
C23C 16/00

US Classification:

118715, 118 315

Abstract:

An apparatus and method for developing latent fingerprints has a breakable capsule containing a cyanoacrylate monomer disposed within an internal chamber of a housing containing a cyanoacrylate catalyst and being adapted for emitting vapors. The housing is impregnated with the cyanoacrylate catalyst or has a layer of cyanoacrylate catalyst on a portion of its interior surface. The apparatus optionally has a breakable capsule breaking mechanism for assisting a user in breaking the breakable capsule within the housing. Upon breaking the breakable capsule, the cyanoacrylate monomer spilling from the breakable capsule reacts with the cyanoacrylate catalyst contained in the housing to create vapor fumes. The vapor fumes contact an object being tested to reveal any latent fingerprints on the object. The apparatus is sized such that it is adapted for placing in any container, room, vehicle, or appropriate open space.

International Classification:

A61B 5/117

US Classification:

427 1, 427145, 4272556

Abstract:

A method for developing latent fingerprints includes placing an apparatus in an area having one or more objects. The apparatus has a breakable capsule containing a cyanoacrylate monomer disposed within an internal chamber of a housing containing a cyanoacrylate catalyst and being adapted for emitting vapors. The housing is impregnated with the cyanoacrylate catalyst or has a layer of cyanoacrylate catalyst on a portion of its interior surface. The apparatus optionally has a breakable capsule breaking mechanism for assisting a user in breaking the breakable capsule within the housing. The user breaks the breakable capsule, causing the cyanoacrylate monomer spilling from the breakable capsule to react with the cyanoacrylate catalyst contained in the housing to create vapor fumes. The vapor fumes contact an object being tested to reveal any latent fingerprints on the object.

US Classification:

118 315, 118715, 118726

Abstract:

An apparatus and method for developing latent fingerprints having a heat source with a removably mounted chamber and sublimation system wherein the sublimation system is in communication with a heat emitting end of the heat source and an internal space of the chamber. Upon activating the heat source, heat transforms a cyanoacrylate of the sublimation system into vapor within the internal space of the chamber. The vapor contacts an object contained within the chamber to reveal any latent fingerprints on the object.

International Classification:

A61B 5/117
G06K 9/00

US Classification:

118 315, 118715, 382124, 362103, 362230, 362231, 362555, 436164

Abstract:

An apparatus and method for developing latent fingerprints having a heat source and sublimation system wherein the sublimation system is in communication with the heat source. Upon activating the heat source, the heat transforms a cyanoacrylate and a sublimation dye of the sublimation system into vapor. The vapor contacts an object to reveal any latent fingerprints on the object. A light source excites the sublimation dye causing photoluminescent emissions which are viewed through filter goggles.
