Filter cover for powered air purifying respirator

Powered air purifying respirator (PAPR) having control panel

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.

Active cooling system for laser imager

A linear translation system for use in a laser imaging system. The linear translation system includes a base member including a pair of longitudinally extending guide rails positioned parallel to each other. A carriage mechanism is carried by the base member, wherein the carriage mechanism is slidably coupled to the guide rails using a three position kinematic design. A rotary to linear motion mechanism is coupled to the carriage mechanism which slidably moves the carriage mechanism along the guide rails. A laser imaging assembly is coupled to the carriage mechanism.

Linear translation system for use in a laser imaging system

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.

Corrugated nonwoven webs of polymeric microfiber

Corrugating apparatus that includes paddles and an ultrasonic welding device. The paddles are attached at one end to a transport that moves about a path. The paddles extend radially from the transport, and each paddle has a free end that is capable of supporting a web as the paddles move about the path. The free ends of the paddles are able to move towards each other to cause the web to corrugate. The ultrasonic welding device is located downstream to where the paddles' free ends move towards each other. The ultrasonic welding device has a horn and an anvil, and the anvil includes the free ends of the paddles.

Corrugating apparatus

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.

Apparel containing corrugated microfiber-containing thermal insulation

Medical imager

Corrugating apparatus that includes paddles and an ultrasonic welding device. The paddles are attached at one end to a belt that moves about a path. The paddles extend radially from the belt, and each paddle has a free end that supports a web as the paddles move about the path. The free ends of the paddles are able to move towards each other to cause the web to corrugate. The ultrasonic welding device is located downstream to where the paddles' free ends move towards each other. The ultrasonic welding device has a horn and an anvil, and the anvil includes the free ends of the paddles.

Fibrous filtration face mask having corrugated polymeric microfiber

A cassette for use in an electronic radiographic imaging system having electronic components. The cassette includes a positioned photoreceptive medium, a light-tight frame, at least one power storage device, and an electronic interface structure for connection to electronic components within the radiographic imaging system. The cassette can also include an electrical interface structure for connection to a power source within the radiographic imaging system.
