Debris capture and removal for laser micromachining

A method of capturing and removing metallic debris created on a target side of a target metal specimen undergoing laser micromachining entails providing a barrier that encompasses the immediate volume surrounding a laser cutting head output nozzle to contain the ejected debris and extracting the debris through a vacuum outlet. A preferred system implementing this approach to debris management includes a barrier in the form of a flexible fiber brush configured in the shape of a ring and positioned to trap ejected debris within a localized area surrounding a target area where the laser beam is incident on the target metal specimen. The ring brush is made of material that is robust to molten metals. An inert gas directed at a high flow rate along the target surface of the metal specimen carries ejected surface debris trapped in the ring brush toward a vacuum outlet.

High-lethality low collateral damage fragmentation warhead

ActiveUS20110146523A1High-lethality low collateral damageReduced collateral damageAmmunition projectilesProjectilesWavefrontDetonation
The present invention provides a high-lethality low collateral damage fragmentation warhead. The case is formed of a material that is pulverized upon detonation of the explosive. As a result, the lethality radius of the pulverized case fragments is no greater than that of the gas blast, thus reducing potential collateral damage. Warhead lethality is improved by placing a pattern shaper between the fragment assembly and the explosive. The explosive and pattern shaper have a conformal non-planar interface that shapes the pressure wavefront as it propagates there through to expel metal fragments from the fragmentation assembly with a desired pattern density over a prescribed solid angle.

Magnetic sweeper

A magnetic sweeper configured to collect magnetic metal debris, such as nails, screws, sheet metal fragments, staples, rivets and the like from a surface, and to permit easy removal of the collected debris from the sweeper is disclosed. The sweeper comprises a non-metallic body, a permanent magnet disposed within the body, a non-metallic cover hingably mounted to the underside of the body and an integrated latch configured to removably secure the cover to the body. The sweeper is configured to removably engage a handle for controlling the sweeper, and in another embodiment, an extendable, telescoping extender may be connected between the coupler and the handle to permit the sweeper to be used in a wide variety of locations. Preferably, the sweeper body is configured to swivel upon application of torque to the handle. In use, the sweeper is passed over metallic debris using the handle to guide the body. As the body passes over such debris, the magnet attracts the debris and holds it against the outer surface of the cover. When debris collection is complete, the cover is unlatched from the body, and swung outwardly from the body, thereby displacing the collected debris to a location outside of the magnetic field of the magnet and permitting the debris to fall away from the cover.

System for measurement of metallic debris in fluid

A debris sensor arrangement is positioned within an enclosed body of fluid for detecting the presence of metallic debris particles therein. Debris detection involves exposure of cantilever beams to the fluid when magnetized within an electromagnetic field to attract the metallic debris particles thereon and induce vibratory motion thereof at a resonant frequency varied by changes in the density of the debris particles magnetically held thereon. Measurement of the resonance frequency reflecting the density of the debris particles within the fluid being tested thereby monitors the corresponding wear of machinery reflected by the debris density.

Magnetic rake with release mechanism

InactiveUS20060186025A1Eliminating magnetic attractionEliminate magnetic fieldSievingScreeningEngineeringJunk box
A magnetic raking device that agitates a ground surface and uses magnetic attraction for collecting ferro-metallic debris, such as nails and screws, at construction jobsites and other locations, includes a release mechanism that temporarily eliminates magnetic attraction of the debris to the rake, thus allowing collected debris to drop from the rake, such as into a trash or recycling container. One type of release mechanism physically removes one or more magnets from the rake body to eliminate magnetic attraction to the rake body. One type of release mechanism uses electromagnets in the rake body that attract ferro-metallic debris when current is allowed to run through the electromagnets, and that allows the debris to drop from the rake when the current is interrupted. The magnetic rake may be used in an inverted position to attract ferro-metallic debris without agitating, and may be used in a non-magnetic state as a conventional rake.
