International Classification:

B41J 2/375

US Classification:

347223

Abstract:

An apparatus for cooling thermally processed media exiting from a thermal processor comprising: a heat conductive member which has first and second opposite sides which is positioned to receive media from a thermal processor, and which removes heat from the heated media as it passes over the first side of the member; and means for removing heat from the member by passing air in contact with and past the second side of the member to remove heat from the member.

US Classification:

250580

Abstract:

A radiographic image reader acquires electronic signals corresponding to a latent image of an object produced by radiation exposure of a photoreceptive medium within a cassette. The radiographic image reader comprises a light-tight enclosure with at least one access port for inserting and removing the cassette. A scanner subsystem is mounted within the light-tight enclosure for scanning the photoreceptive medium within the cassette to initiate the acquisition of the electronic signals representative of the latent image. A cassette registration and interface subsystem within the light-tight enclosure comprises an electronic interface structure for electronically connecting the photoreceptive medium within the cassette to an electronic component external of the cassette to obtain the electronic signals corresponding to the latent image.

Assignee:

Minnesota Mining and Manufacturing Company - St. Paul MN

International Classification:

D02G 300

US Classification:

428362

Abstract:

Apparel having thermal insulation containing a corrugated nonwoven web and a means for retaining the shape of a corrugated web. The shape-retaining means is not coextensive with the corrugated nonwoven web and is secured to the valleys of the corrugations. The corrugated nonwoven web has a solidity of 0. 1 or less and contains microfiber and crimped staple fibers that have a percent crimp of at least 15 percent.

International Classification:

B32B 516

US Classification:

428323

Abstract:

A composite structure contains a lofty corrugated nonwoven web of polymeric microfiber that is maintained in a corrugated condition by securing a fabric to the corrugated web at the valleys of the corrugations. The composite structure is made without substantially effecting web loft by (i) introducing the nonwoven web to the ends of a plurality of spaced paddles, (ii) causing the spacing between the ends of the paddles to decrease to corrugate the nonwoven web, and (iii) securing the fabric to the corrugated nonwoven web at the valleys of the corrugations. A composite structure of this construction made by this method provides very good filtration performance, making it particularly suitable for use as a filter in a cup-shaped face mask. The composite structure also is very suitable for use as thermal insulation in apparel.
