Abstract: A door has a core that includes a porous layer having a thickness and two opposing major surfaces. In one construction, the core also includes three fire-retardant layers, and two of the fire-retardant layers are separated by the porous layer. The porous layer and the fire-retardant layers are coupled together. Other constructions include one or more fire-retardant layers in balanced or unbalanced placement around the porous layer.

Abstract: Immunoadhesins active against infectious bacterial agents, e.g., the bacterium responsible for anthrax, are described and claimed. These chimeric molecules feature stabilizing immunoglobulin portions linked to bacterial proteins having affinity for host receptors. Methods of using these immunoadhesins are also desribed.

Abstract: The contact fingers of electrical switching apparatus have radial convex surfaces centered on the pivot pins which seat on concave surfaces in the molded contact carrier to transmit bending loads on the pin into the carrier. A seal member which snaps onto the end of the pivot pin has fins which extend between the contact fingers to block flow of arcing gases through the carrier. For lower current ratings, some of the contact fingers are replaced by annular spacers which also transmit bending moments into the carrier and restrict gas flow. A stop ledge on the carrier against which the contact springs bias the contact fingers has a recess which allows the center fingers to project farther toward the stationary contacts so that the arc toes on these fingers are the last to separate on opening and the arc is concentrated on them.

Abstract: A molded case circuit breaker is provided with ground fault protection by a modular unit which drops into a pole compartment in the molded casing in place of a pole assembly. The modular unit includes a housing forming an open faced cavity across which is mounted a printed circuit board with the ground fault circuit components and trip solenoid projecting into the cavity. The housing also supports the ground fault sensing toroid in a position for the appropriate conductors to pass through the coil. A bell switch and auxiliary switch are positioned by the housing for actuation by levers mounted on the cradle pin and crossbar, respectively. An integral leaf spring molded into the housing accommodates for manufacturing tolerances and fixes the positions of the various components.

Abstract: A method of and apparatus for recapturing data from scanning devices and storing the captured data in digital form using a method that allows for easy, fast and reliable access for viewing, printing, transmitting, et cetera. More specifically, the method of the present invention allows institutions such as banks to "touch" data that has been captured using high speed reader/sorter devices. The invention interacts with such devices to store scanned digital images to storage devices using a hierarchical storage management module in order to migrate less accessed images to more cost effective storage media, such as optical disk and/or tape. Users access copies of the scanned items using an application that queries a database that holds pointers to the actual location of the physical digital image. The location of the scanned image is transparent to the end-user.

Abstract: A high capacity time-division switching system is disclosed which includes a digital data transmission system for transmitting both digital data words and synchronizing information. The predetermined bit positions of each data word, which bit positions are to convey data only, are encoded and transmitted as a combination of the true and complement representation of those digits. The remaining bit positions, which are used to convey both data and synchronizing information, are encoded and transmitted as true representations only. A digital data receiver responds to the data so encoded by extracting synchronizing information based on the violation of the predominately true and complement coding format.
