Filed: 2001-01-05
Granted: 2009-12-01
Abstract: A pressure relief apparatus includes a valve having a body. A shaft is rotatably disposed in the body and has an exterior end extending through the body. A  plug, which may contain an internal passageway, is mounted on the shaft and is disposed in the fluid flowpath. The body is engageable with the system to expose the plug to the pressurized fluid so that the pressurized fluid acts on the plug to exert a torque on the shaft which is offset from the center line of the plug.  The apparatus further includes a linkage assembly configured to translate the torque exerted on the shaft into an output force. A release device, such as a buckling pin, a magnet, an electromagnet or a fusible plug, is connected to the linkage assembly and is configured to release the shaft when the output force exceeds a predetermined limit. Preferably, the linkage assembly is adjustable to vary the magnitude of the output force corresponding to a given torque. A low torque seal secured in place by a retaining ring is disposed in the body to prevent fluid from leaking through the body past the plug.

IPC: G06T1/00
Filed: 2001-11-16
Granted: 2003-07-15
Abstract: An image processing system for digital printing for improving throughput and efficiency of the transfer of image data to imaging devices, such as lasers, while allowing for dynamic and continuous adjustment of image size and registration (i.e., alignment) on recording media. A buffer memory structure is configured to receive data from raw image files. Specific portions of data are copied from the raw image files into a buffer memory structure and, for compilation of the final image, into an image buffer. Image overlap is resolved by copying data into the image buffer according to a defined hierarchy. Using a phase locked loop, image size and registration are adjusted to optimize the appearance of the final image on the recording medium. The optimization is performed dynamically and continuously, thereby providing a uniform final image. Many aspects of the operation of the image processing system may be under the control of a digital computer.

Title: Lubricant composition for ammonia based refrigerants with good seal performance
Inventor: LI HSINHENG
IPC: C10M107/02
Filed: 2001-03-15
Granted: 2009-10-27
Abstract: A problem with refrigeration systems using ammonia as the refrigerant and hydrocarbon lubricants is that the seals/gaskets of the systems have a tendency to harden and shrink. This can cause leakage of the refrigerant and eventually require disassembly of the equipment and replacement of the seals. The addition of a small amount polyether having an aromatic fragment of 6-18 carbon atoms or an aliphatic fragment of 10-22 carbon atoms can soft en the seals and partially re-swell the seals solving the leakage problem and avoiding expensive maintenance costs. Alternatively a polyether of 1,2-butylene oxide which is more oil soluble than most other polyethers with a smaller Z group e.g. derived from alkanols of 1 to 9 carbon would be effective at reducing hardening and shrinkage.

Abstract: A controller for a pulse width modulated electrical drive or a dual-mode, pulse width modulated/variable voltage inverter drive is coupled to sensors within a filter at the drive output. Upon detecting failure of the filter or filter components (e.g., a capacitor short or blown fuse) through the sensor s, the controller either shuts down the drive or automatically switches the dri ve operating mode to an output mode which does not require filtering. Damage to the electrical system or downhole equipment from transmission of unfiltered or improperly filtered power may thus be averted upon failure of the filter or a filter component.
