Title: Compressed natural gas fuel tank for vehicles
Inventor: DAVIS WILLIAM F JR
IPC: F17C13/08
Filed: 1995-05-19
Abstract: A compressed natural gas fuel tank for ve-hicles employing internal combustion engines. A fuel tank (40, 42) of heavy gauge metal is in-terposed within the vehicle frame (10) as inte-gral portion thereof. Overlay channel members are welded or otherwise affixed to the tank and then welded or otherwise affixed to the side rails (12, 14) or channel member (36, 38) of the ve-hicle frame. The tank, of heavy gauge metal and non-circular cross section, is also welded or oth-erwise appropriately affixed to the vehicle floor (76). The tank is capable of receiving natural gas at high pressure levels, while also serving structurally as a frame element, providing con-tinuity of the side rail members (12, 14) of the frame (10), while also serving to further intercon-nect the vehicle floor (76) with the side rails (12, 14). Also presented are tank assemblies in which a tank housing receives a plurality of cylindrical pressure tanks of composite material construction (122, 158, 178). The cylindrical tanks (122, 158, 178) are nested within the tank housing (118, 154), which also serves as an integral part of the vehicle frame (100, 140). A manifold (130, 160) with inlet (132, 134) and outlet (162, 164) valves interconnects the cylindrical tanks (122, 158, 178).

Title: Image display apparatus
Inventor: AZUMA HIROO
IPC: H01J29/94
Filed: 1996-12-18
Abstract: An image display apparatus which is subjected to getter flashing during manufacturing, for the purpose of increasing the degree of vacuum in the air-tight container thereof, is provided with a getter scattering prevention member comprised of a plurality of getter scattering prevention walls.  The getter scattering prevention walls prevent getter material from scattering to the image display portion of the image display apparatus, while allowing for smooth conductance of gas in the air-tight container during evacuation.  Thus, evacuation by the getter can be further improved by increasing the area to which getter adheres to, deterioration of the image quality can be prevented by not allowing getter to adhere to the image display portion, the air-tight container can be evacuated in a shorter time, irregularities in brightness of the screen due to uneven pressure within the display portion can be done away with, and a higher degree of vacuum can be attained.  Consequently, an image display apparatus with good image quality and a long life expectancy is provided.

IPC: G09C1/00
Filed: 1997-01-06
Abstract: In a cryptosystem, communication terminals and encryptors can be grouped physically and logically.  The communication mode can be switched by the encryptor between ciphertext communication and plaintext communication.  The encryptor includes the session key memorizing unit for memorizing the session key and the mode switch for switching the communication mode between ciphertext communication and plaintext communication. The key manager distributes the session key generated by the session key generating unit and the valid/invalid information set by the valid/invalid setting unit to each encryptor.  The valid/invalid judging unit judges whether the communication data should be sent in ciphertext or plaintext using the mode switch and the valid/invalid              . information.

Patent CA-2198308-A1 (CA)
Title: System and method for hierarchical multicast routing in atm networks
Inventor: CHEN XIAOQIANG
IPC: H04L12/56
Filed: 1997-02-24
Abstract: The present invention extends the PNNI protocols to support hierarchical multicast routing and signaling for ATM networks. The invention utilizes an extension to a core-based tree algorithm. Instead of a single core node, core nodes are maintained in each peer-group and at each level of the hierarchy. The advantage of this is that one single core node is not overloaded. Additionally, this increases fault-tolerance because there are no single points of failure. As would be understood, the present invention is highly scaleable because of the hierarchical nature of PNNI. In addition, the scheme supports multiple senders and dynamic membership changesto the multicast group. Quality of service requirements can be negotiated duringconnection setup and are guaranteed during the course of the connection. Though some additional topological information has to be flooded in the peer-groups to compute efficient multicast routes, the overheads to the connection management are minimal The multicast tree is built incrementally and the cost of the tree is comparable to the cost of the Steiner Tree computed using some standard heuristics.

Title: Thermally sprayed metal-based composite coatings
Inventor: DALLAIRE SERGE
IPC: C23C4/06
Filed: 1997-04-03
Abstract: Abrasion-wear  resistant  thermal  sprayed  stainless  steel based  coatings  are  disclosed,  particularly  arc  sprayed stainless  steel coatings  containing  titanium  diboride crystals which impart hardness to the soft stainless steel matrix and enhance their resistance to hard abrasive media. There is also disclosed a process for making core wires composed of stainless steel sheaths and cores composed of a mixture of titanium diboride,  stainless steel and certain additives.    During  the  thermal  spraying  operation,  the stainless steel sheath and the core material melt to form a composite  coating  containing  fine  hard  titanium  boride crystals dispersed within stainless steel.  The arc sprayed stainless  steel  based  coatings  are  more  resistant  to abrasion wear than solid pieces of type 304 stainless steel and  other  arc-sprayed  stainless  steel-based  coatings available on the market.  Although reference is made mainly to the arc spraying process,  the core wires are suitable for other thermal spraying processes that use wires as the feed material,    for  instance  combustion  and  arc-plasma spraying and weld overlay surfacing techniques.
