Patent CA-2220477-C (CA)
Inventor: CULVERWELL GREGORY ADRIAN
IPC: F15B21/06
Filed: 1997-11-07
Granted: 2005-03-29
Abstract: The invention concerns a bore sealing valve which is operated by liquid pressure, typically water. The valve has a first member defining an internal bore of round cross-section and a second member which can move in opposite directions in the bore. One of the members has a shoulder and the other a recess accommodating a flexible seal. The seal flexes radially relative to the recess, under the effects of differential pressure in respective high and low pressure regions of the byre, when the second member moves in one direction in the bore. This makes sealing engagement with the shoulder to close the valve and isolate the high and low pressure regions of the bore from one another. The seal disengages from the shoulder when the second member moves in the opposite direction in the bore to open the valve and place the regions of the bore in fluid communication. That end of the seal which engages first with the shoulder on closure of the valve and which disengages last from the shoulder on opening of the valve is closer to the low pressure region of the bore than the opposite end of the seal. With these features, the bore sealing valve is suitable for use in a water environment.

Title: Method for generating moisture, reactor for generating moisture, method for controlling temperature of reactor for generating moisture, and method for forming platinum-coated catalyst layer
Inventor: MOROKOSHI HIROSHI
IPC: C01B5/00
Filed: 1997-01-27
Granted: 2003-02-18
Abstract: The invention further reduces a size and cost of a reactor for generati ng water from oxygen and hydrogen, provides high-purity water in an amount necessary for practical use safely, stably and continuously, and allows a platinuin- coated catalyst layer formed on an inner wall of a reactor body to maintain high catalytic activity over a long period of time. Specifically, the reactor comprises a body made of a heat-resistant material and having an inlet and an outlet for water/moisture gas, has a gas-diffusing member provided in an internal space  of the body, and has a platinum coating on an internal wall surface of the body. Hydrogen and oxygen fed from the inlet is diffused by the gas-diffusing member and th en comes into contact with the platinum coating to enhance reactivity, thereby producing water from hydrogen and oxygen. A temperature of the reactor for generating moisture, wherein hydrogen is reacted with oxygen at a high temperature to generate moisture, is held to be below an ignition temperatur e of hydrogen or a hydrogen-containing gas so that hydrogen is reacted with oxyge n while preventing explosive combustion of hydrogen and oxygen. The platinum- coated catalyst layer on the internal wall of the reactor body is formed by treating the surface of the internal wall of the body, cleaning the treated surface, forming a barrier coating of a nonmetallic material of an oxide or nitride on the wa ll surface, and forming the platinum coating on the barrier coating.

Title: An apparatus for protecting connectors on circuit packs
Inventor: PATEL NARESH C
IPC: H04B10/2581
Filed: 1999-06-22
Granted: 2002-09-17
Abstract: A protection assembly for connectors is included on a circuit pack to prevent damage caused when a connector is removed while signal power is still being supplied to the circuit pack. More specifically, the protection assembly is disposed on the front side of the circuit pack to prevent access to the connector until signal power is automatically cut off from the circuit pack. In one embodiment, the circuit pack is the type having a lever arrangement capable of causing the circuit pack to engage and disengage the backplane of an equipment frame. When the circuit pack is engaged in the backplane, signal power is supplied through the connector that is accessible, for example, on the face plate of the circuit pack. The protection assembly includes a first shield member mounted on the face plate of the circuit pack in a location adjacent to the connector.  The protection assembly further includes a second shield member mounted or otherwise formed on the lever arrangement. When the circuit pack is engaged in the backplane, the first and second shield members cooperate to prevent access to the connector protected thereunder. To expose the connector, a technician would have to operate the lever arrangement to separate the first and second shield members. Because the circuit pack is disengaged from the backplane by action of the lever arrangement, signal power supplied to the connector is therefore automatically cut off before the first and second shield members are separated to expose the connector.

Abstract: The software program provides a unique arrangement and integration of CD drive, data server, and PC hard disk drive technologies. The program provides open- ended, flexible, and timely updating of software programs and content for users at a remote site because the user can download individual updated program modules as needed from a designated information site through a data server to a PC hard disk drive during a program run. Therefore, the user is not required to download the updated program, await the next release of a CD containing the updated program, or use the updated program directly on a designated information site. In addition to the program modules on the CD, the user can use downloaded updated program modules from either the current or a previous program run. The updated program modules are either replacements for those on the CD or additional program modules to the entire program. The program includes linking software, such that each of the program modules on both the CD and the PC hard disk drive contains an identical yet independent software interface that allows interconnecting to all other program modules. Because the user may also download updated program modules from the designated information site to the PC hard disk drive as needed during a program run, the present invention provides seamless interactivity between program modules on the CD, downloaded program modules on the PC hard disk drive, and replacement or additional program modules at the designated information site.
