IPC: F04C13/00
Filed: 1999-02-24
Abstract: A displacement pump for a relatively high pressure performance environment includes a casing with first and second ends, with rotors driven in the casing to effect pumping. Flushing fluid (such as sealing water or substantially fiber-free foam) is introduced into a clearance between the rotors and the interior surface of the second end of the casing to keep the clearance substantially free of undesirable particles or fibers, typically fibers (such as glass fibers) having greater abrasiveness than cellulose fibers, or fibers (such as synthetic fibers, or synthetic material coating cellulose fibers) having poorer heat resistance than cellulose fibers. The flushing fluid may be introduced into the clearance in a number of different ways as long the clearance is kept substantially free of the undesirable particles or fibers. The flushing fluid is introduced, preferably through a check valve, at a pressure at least slightly higher than the output pressure of the pump.

La fibre optique peut également être utilisée pour détecter, d'une part, la transformation du matériau de la martensite à l'austénite sur la zone chauffée et, d'autre part, la température de ladite zone chauffée, cette information pouvant être utilisée pour diriger le déploiement du dispositif et réduire la surchauffe du tube et du matériau entourant la partie externe du tube.
Patent CA-2272301-A1 (CA)
Inventor: ASSAF MAHMOUD
IPC: G11B20/18
Filed: 1997-12-02
Abstract: A computer system having a monitor, disk drive, and central controller is disclosed. The computer manufacturer uses a method for expanding the reserve area of a disk drive to allow computer systems manufacturers to change the storage capacity of the reserve area. The method includes setting up a password with the disk drive manufacturer to enable two commands. One command reads the maximum address or largest track number that the user has access to. The second command allows for setting a new maximum address to which the user has access. The firmware of the disk drive is updated with the new maximum address. Once the two commands have been used to expand the reserve area, the computer system manufacturer can add critical data, and critical program instructions to the expanded or new reserve area. The computer manufacturer may decide to store a portion of the virus scan program in the expanded reserve area, or store a portion of the basic input output system (BIOS) so that a smaller BIOS read only memory (ROM) can be used for the computer system, or the computer manufacturer can store emergency boot up instructions in the reserve area in the event there is damage to the disk.
