Title: Heating element support for an electric heat treating furnace
Inventor: MOLLER CRAIG A
IPC: F27D1/00
Filed: 1998-05-15
Abstract: A support or hanger for an electric heating element in a heat treating furnace is disclosed. The heating element support includes a support arm having first and second end portions. First and second ceramic sleeves extend transversely through the support arm and a bracket surrounds at least three sides of the support arm. The bracket is dimensioned and positioned to engage with, and thereby support, the electric heating element. First and second pairs of ceramic spacers are disposed annularly on said first and second ceramic sleeves, respectively. The ceramic spacers are positioned between the bracket and the support arm to prevent contact between the support arm and the bracket. A pin is disposed within each of the first and second ceramic sleeves and extends through the bracket to support and retain the ceramic sleeves, the ceramic spacers, and the bracket on the support arm. In this arrangement, the heating element bears on the metallic bracket and does not cause wear or damage to the ceramic elements. The bracket also provides a shield against contamination and metallization of the ceramic components. A cap is disposed over the first end portion of the support arm and a portion of the bracket adjacent thereto and is supported and retained on the bracket by the inboard retaining pin. The cap provides a shield for the ceramic components, particularly those that are disposed along the floor or bottom of the furnace hot zone.

Title: Improved structures and method of manufacture for gas diffusion electrodes and electrode components
Inventor: SHAIKH KHALEDA
IPC: H01M8/10
Filed: 1998-12-23
Abstract: This invention pertains to gas diffusion electrodes and diffusers with new improved structures suitable for systems using ion conducting membranes as the electrolyte, and automated methods of manufacture that lend themselves to continuous mass production. Unexpected improvements in gas and vapor transport through the electrode are realized by incorporating a new dispersion process in the construction, reformulating the applied mix with solution additives, and creating a novel coating structure on a conductive web. Furthermore, combining these changes with a judicious choice in coating methodology allows one to produce these materials in a continuous, automated fashion.

Inventor: PATEL MAHESH
IPC: H04W8/18
Filed: 1997-12-15
Abstract: Selective carrier denial in a cellular system restricts some or all carrier-handled calls from a given cellular subscriber while simultaneously allowing other cellular calls. A restriction flag or indicator in a Visitor Location Register (VLR) of the cellular system is set by a Home Location Register (HLR) which contains a list of those carriers denied to subscribers. When the restriction flag is set, the HLR is interrogated to determine if the call is restricted. Alternatively, the restriction flag may reside within the subscriber's mobile phone. Further, the VLR or mobile phone may, respectively, contain a list of denied carriers and internally determine if carrier denial applies without resort to the HLR.

Title: Method for two party authentication and key agreement
Inventor: PATEL SARVAR
IPC: H04L29/06
Filed: 1999-07-20
Abstract: According to the two party authentication method, a first party generates and transfers a random number to a second party as a first challenge. The second party increments a count value in response to the first challenge, generates a first challenge response by performing a keyed cryptographic function (KCF) on the first challenge and the count value using a first key, and transfers the count value, as a second challenge, and the first challenge response to the first party. The first party verifies the second party based on the first challenge, the second challenge and the first challenge response. The first party also generates a second challenge response by performing the KCF on the second challenge using the first key, and transfers the second challenge response to the second party. The second party verifies the first party based on the second challenge and the second challenge response. For instance, the first and second parties can be a network and mobile, respectively, in a wireless system. Also, based on the first and second challenges, both the first and second parties may generate another key.
