Patent CA-2141225-A1 (CA)
Title: Reinforced concrete structure
Inventor: BROWN CARL W JR
IPC: C04B41/51
Filed: 1995-01-27
Abstract: A metal coating of typically a valve metal, especially a titanium metal coating, is applied by thermal spraying to the surface of concrete, most particularly steel-reinforced concrete. The metal such as titanium may be sprayed by any one of several thermal spraying techniques including flame spray, electric-arc spray, plasma spray, high-velocity oxyfuel spray, or detonation gun spray. The metal coating should be tightly adhered to the concrete and desirably will have a porosity to facilitate extensive coating of the metal itself, as well as facilitate any activation that may be needed for the metal. Such activation can be in the form of an active material which allows the coating to function catalytically. One coating option is to apply a solution onto the spray-applied metal, then polarize the metal anodically to effect deposition of active material on the metal. Another option includes depositing active material directly onto the concrete, then applying an adherent, electrically conductive overlay such as a titanium metal coating to the treated concrete.

Title: Radiant thermal integration with regenerative heating in a high temperature electrochemical converter
Inventor: HSU MICHAEL S
IPC: H01M8/04
Filed: 1993-11-24
Abstract: A high temperature electrochemical converter provides regenerative heating of electrochemical converter reactants to an operating temperature using an exhaust flow. Additionally, a radiant thermal integration configuration transfers heat from as electrochemical converter assembly (20) to power a bottoming plant, thereby achieving flexible and efficient system design. In a fuel cell operating mode, for example, it facilitates the recovery of waste heat of the fuel cell reaction for integration with bottoming thermodynamic devices, such as a gas or steam turbine (120). The radiant thermal integration is accomplished by efficient radiative heat transfer between the external columnar surface of the converter assembly (24) and the heat transfer assembly (34) containing the working medium of a heat sink or a heat source device, and by a regenerative process where incoming reactants (17, 19) are heated to the converter operating temperature by outgoing exhaust.

Patent CA-2154048-A1 (CA)
Title: Wafer support structure for a wafer backplane with a curved surface
Inventor: FERREIRA JOHN
IPC: C23C14/50
Filed: 1995-07-17
Abstract: The wafer support structure is used with a movable backplane having a curved upper surface which is moved between a wafer access position and a wafer process position to clamp a wafer against a clamping structure during processing. A guide ring surrounds the backplane and a floating ring is spring-mounted on the guide ring by flat, elongated lift springs. RF bias springs are positioned on top of the floating ring along with wafer support pins which support a wafer above the curved backplane surface. When the backplane is moved toward the clamping structure to clamp the wafer, the RF bias springs make electrical contact with a portion of the clamping structure, and the clamping structure acts against the floating ring to flex the lift springs and lower the floating ring such that the wafer is transferred to the backplane surface to be clamped against the clamping structure. When the wafer is clamped, the support pins are out of contact with the wafer. The wafer is stably supported by the support pins over the backplane surface during access of the wafer and is securely clamped between the backplane and clamping structure away from the wafer support during processing of the wafer. A filler ring around the backplane reduces formation of a secondary plasma.

Title: Continuously shoring an excavated hole
Inventor: BAZIUK MORRIS
IPC: E02D17/08
Filed: 1995-12-14
Abstract: Excavation from the ground surface to an underground element to be located is effected using a series of sleeve members which slide through an opening in a platform into the ground. The sleeve members thus connect together in a coaxial aligned row to form a cylindrical entry sleeve through which a person can climb downwardly to the excavated element. Excavation occurs by injecting high pressure liquid into the area within the sleeve members and by extracting the slurry so formed through a discharge duct which is integrally formed on one side wall on the sleeve member. The sleeve members gradually and continually descend into the hole as the excavation occurs to automatically form shoring to hold the surrounding soil against collapse.
