Abstract: A wall lining for a furnace (10) includes a refractory layer (14) having a hot face (16) exposed to the interior of the furnace. A plurality of elements of a high thermal conductivity material (18), such as copper wires or rods, extend from the outer shell (12) of the furnace into the refractory lining (14). The elements (18) provide a continuous heat conduction path to the outer shell (12) of the furnace. A cooling jacket (22) removes heat from the outer shell. The elements (18) are dispersed in the refractory lining (14) to provide a substantially uniform temperature across the hot face of the furnace in the vicinity of the elements. The wall lining may be formed by fixing an array of the elements to the inside wall of the outer shell of the furnace and applying a refractory material to the inside wall.

Title: Cleanable guarded surgical scalpel blade remover
Inventor: PIERCE ROBERT W
IPC: A61B17/3211
Filed: 1996-10-09
Granted: 1999-08-03
Abstract: This invention relates to an improved guarded surgical scalpel having a movable guard that can be retracted to expose the blade and that can be extended to cover the sharp cutting edge of the blade. The guard is also mounted for rotatable movement with respect to the handle. A blade carrier is mounted to the guard to allow relative longitudinal movement between the guard and the blade carrier. The blade carrier is also removably mounted to the handle. This mounting arrangement for the handle, guard and blade carrier allows the guard and blade carrier to be rotated away from the handle so the surfaces of the handle, guard and blade carrier can be exposed. This facilitates cleaning of the guarded surgical scalpel after use.

Abstract: A transmissive, backlit color twisted-nematic or super-twisted-nematic liquid crystal display employing a front fiber-optic faceplate or optical equivalent as a front retaining element of a liquid crystal cell that increases viewing angle between the display and a viewer while minimizing or eliminating undesirable variations in luminance, contrast ratio and chromaticity is described. The fiber-optic faceplate or optical equivalent includes cylindrical optical features and interstitial cladding material of greater optical index than the cylindrical optical features. The interstitial cladding material may include an opaque mask blocking layer to prevent the interstitial apertures from diffracting off-axis light into an observer's viewing cone. In particular the liquid crystal display includes dual negative retarders, and a light shaping element such as a brightness enhancing film on the illumination source that increase the effective viewing angle between the display and a viewer while minimizing undesirable variations in display chromaticity, luminance, and contrast ratio. The front fiber-optic faceplate or optical equivalent works in conjunction with the dual negative retarders and the light shaping element to provide an improved contrast ratio with a perfectly symmetric viewing angle and to eliminate grey scale inversions.

Abstract: The method for electronically conveying large blocks of data between geographically-remote locations by uploading the sender's data to the local hub site of a service provider's network, earmarking that data with an electronic invoice, transmitting that data via the service provider's high speed network to a secondary hub site that is local to the recipient's geographic location, and downloading the data from the second hub site to the recipient's network. Duplicate archival versions of the transmitted data may be maintained at two geographically-distinct locations, such as the service provider's primary and secondary network hub sites. The total number of network connections may be reduced with a minimum number of alternative connections maintained to ensure data delivery in the event of a network connection failure. Value-added services may be performed on the data either prior or subsequent to its transmission between the primary and secondary hub sites.
