Abstract:

A porous structure having a plurality of bonded sheets each sheet having at least one aperture that partially overlaps an aperture of at least one other sheet. A method of producing a porous structure including stacking a plurality of sheets each sheet having a multiplicity of apertures, and bonding each sheet to its adjoining sheet. An open-pore network structure having a multiplicity of sheets each having a repeatable pattern. At least a portion of each sheet is bonded to the web of an adjacent sheet. The porous area of at least one of the sheets is askew to the porous area of at least another of the sheets. An open-pore structure having a multiplicity of bonded sheets, each sheet having a repeatable pattern defining a multiplicity of perforations, and a plurality of apertures defined by the repeatable pattern, the apertures extending through the perforations of at least two adjacent plates.

International Classification:

H01L021/302
H01L021/461

US Classification:

438/689000

Abstract:

Method for producing a multiplicity of undercut micro recesses in a surface of an article, such that the article exhibits a greater fractal area at a level below the surface than is exhibited at the surface. The method comprises applying a maskant layer to a selected surface of the article, removing the maskant layer in selected loci to expose underlying portions of the article surface in a selected pattern, applying an etchant to the exposed underlying surface portions for a time sufficient to etch the exposed portions of the article and to enable the etchant to etch beneath portions of the remaining maskant layer, and removing the remaining maskant layer to provide the surface in exposed condition with the multiplicity of undercut recesses, to provide an engineered pattern of the recesses.

International Classification:

A61B 508

US Classification:

128728

Abstract:

An inhalation device for use in breathing exercises is described. The exerciser includes a thin-walled bellows whose upper end is attached to a top housing member and whose lower end deflects upward upon withdrawal of air from an opening in the upper end of the bellows. Deflection of the bellows allows accurate measurement of the volume of air inhaled by a patient and a true indication whether an inhaled breath is being held. Slotted support arms connecting the top housing member and a bottom housing member permit collapse of the device for storage and shipment of the exerciser as a compact unit. A weight attached to the lower end of the bellows provides a biasing force to assure return of the bellows to a fully extended position even after long-term storage of the device in collapsed form.
