Filed: 1995-02-10
Abstract: A housing is provided for a circuit breaker. The circuit breaker has contacts capable of being in an open state or a closed state, of movement between the open and closed states, and of generating a hot gas in consequence of that movement. An electronics module is provided for controlling movement of the contacts from the closed state to the open state. The housing has a first portion housing the contacts and a second portion housing the electronics module. The second portion is formed of a material subject to damage by the hot gas, and the first portion is constructed to protect the second portion from damage by the hot gas. The first portion is ideally formed of a thermosetting material resistant to damage by the hot gas and the second portion is ideally formed of a thermoplastic material, which reduces the cost of manufacturing the housing. A quick-mounting construction for assembling the second portion with the first portion further reduces the cost of assembly.

Title: Method of minimizing skip coating on a paper web
Inventor: DAMRAU WAYNE A
IPC: D21H23/32
Filed: 1993-10-25
Abstract: A fountain applicator for applying coating liquid onto a web of paper carried past the applicator, has a coating liquid flow path that includes a curved surface along which a sheet of the coating liquid is flowed to subject the sheet to centrifugal force to cause air entrained in the coating liquid to move toward one side of the sheet away from the curved surface. After being flowed along the curved surface, the sheet of coating liquid is directed toward the web in a free standing jet curtain of coating liquid, to contact an opposite relatively air-free side of the coating liquid sheet against the web surface while the one side of the sheet is out of substantial contact with the web surface. Contacting the web with coating liquid that is relatively free of entrained air minimizes the occurrence of skip coating on the web, especially when the web is travelling past the applicator at high speeds.

Title: Method and apparatus for data transfer and storage in a highly parallel computer network environment
Inventor: SPIRAKIS CHARLES S
IPC: G06F11/30
Filed: 1994-01-19
Abstract: A method and apparatus for sharing a single storage device among an arbitrarily large number of parallel processes with typically no wasted memory space and continued operations even when an error or interrupt occurs is disclosed. In a networked computer system having a communication network connecting a primary storage device between one or more computer devices and a secondary storage device, when some type of interrupt is generated or an error condition occurs or is otherwise indicated, a transfer of data from primary to secondary storage is indicated. A state indicator having at least a non-backup and a backup state may be set to the backup state to indicate that a data transfer from the primary storage device to the secondary storage device should occur.  Alternatively, the transfer from the primary to the secondary storage device can begin without the use of a state indicator. When the state indicator is in the backup state, a predetermined maximum number of processes will work on transferring data from the primary storage device to the secondary storage device. Other processes will transfer data from the computer to the primary storage device. The process which completes the transfer of data from the primary storage device to the secondary storage device then resets the state indicator to its normal state. Preferably, other processes which are already executing at the time when the state indicator is set to the backup state continue to execute to completion.

Title: Anti-sense rna for cab transcript to reduce chlorophyll content in plants
Inventor: JOHNSON-FLANAGAN ANNE M
IPC: C12N15/82
Filed: 1995-12-12
Abstract: The initial steps in photosynthesis are the conversion of light energy into chemical energy. This conversion is performed by the multisubunit protein-pigment complexes of the thylakoid membranes. Oxygen-evolving photosystems contain photosystem I (PSI) and photosystem II (PSII), which act in tandem. In PSII, the majority of light-adsorbing chlorophylls are attached to LHCII, the light harvesting complex associated with this photosystem. LHCII is the most abundant member of the family of chlorophyll a/b binding (CAB) proteins. A gene encoding a type I chlorophyll a/b binding protein of LHCII (ICABPSII) has been cloned from Brassica napus L. An anti-sense RNA of this gene has been used to reduce the amount of chlorophyll a/b binding protein and thus reduce the amount of chlorophyll in the resulting transgenic plants. By using "site"  specific promoters the reduction of chlorophyll can be targeted to specific organelles in the transgenic plant and thus can be used to reduce the green colour at these sites. Thus it is possible to use the anti-sense RNA of a chlorophyll a/b binding protein as a means for degreening, for example fruits, seeds or floral parts in transgenic plants.

Patent CA-2182254-A1 (CA)
Inventor: KOU WEIDONG
IPC: G06F21/62
Filed: 1996-07-29
Abstract: A generic secure file format to solve problems associated with secure storage and interchange. The file format allows multiple files to be wrapped into a single entity for storage or transmission interchange. Each file can have different security requirements from that of other files. Different file types can be interchanged under a single wrapper in this secure file format. The secure file format also allows one file to be divided into multiple sections and wraps them into a single file. Each section of the file has its own security protection. This enables only sensitive information to be protected, and leaves other sections with less or no security protection. This results in higher performance since security related operations are only required for a small portion of the file.

Patent CA-2186180-A1 (CA)
Title: Well completion system and method
Inventor: BUSSEAR TERRY R
IPC: E21B43/10
Filed: 1996-09-23
Abstract: The method includes running a liner, production packer and polished bore receptacle (PBR) into a well on the production tubing string, cementing the liner in place by pumping cement through the production tubing string, setting the packer, and optionally thereafter releasing an upper portion of the tubing string from a PBR. A seal assembly isolates the PBR bore from cement exposure during liner cementation. Annular pressure produces a reverse fluid surge and circulating flow to prevent PBR seal area contamination when the tubing string is lifted away from the PBR. A connecting assembly 12 is suspended from a production tubing string 11 to position a liner 17 in a wellbore. The connecting assembly transmits rotational and longitudinal forces from the production tubing string to properly position and cement the liner in the wellbore. The connecting assembly includes a device 20 to limit torque forces on the tubing string, and a longitudinal slip mechanism 28 permits limited longitudinal movement between the connecting assembly and tubing string. A packer 15 is set to seal between the production tubing string 11 and the well casing. An extended length of tubing 11a extends below the packer to provide a continuous tubing/liner-casing overlap area for cementation.
