20080269398 | Modified Polymer with Partitioning Agent - A modifier material and method for making the same is characterized by the addition of a partitioning agent to a polymer material such as synthetic rubber to prevent reagglomeration of the rubber. The partitioning agent reduces the time required to disperse the modifier material in a material to be modified and also reduces the viscosity of the modified material so that the modified material is easier to handle. The partitioning agent preferably includes a mixture of phenyl formaldehyde resin and precipitated silica gel. | 10-30-2008 |
20090013903 | Barrier Based Fuel Resistant Binder - A fuel resistant binder is characterized by the addition of a carrier curing agent to a modified, unmodified or emulsified asphalt material formed of a mixture of hot, cold or emulsified asphalt and carrier and activator materials. The carrier curing agent preferably is a polyurethane moisture curing solution. A cross-linking material and aggregate are also mixed with the binder to form a material suitable for patching cracks and holes in pavement and the like. The activator assists the polymer material in linking with the asphalt while the carrier prevents the formation of gel or lumps within the asphalt. The carrier curing agent resists the penetration of fuel into the binder. | 01-15-2009 |
20100187718 | RE-CAPSULATION OF SYNTHETIC RUBBER POLYMER - A method for making a modified polymer is characterized by re-capsulating the polymer via extrusion. A cross-linking agent is mixed with particles of synthetic rubber material to form a mixture which is then heated and delivered to an extrusion device. The extrusion device further heats the mixture and produces strands of modified polymer material which are cooled and pelletized to form small pellets of re-capsulated modified polymer. A partitioning or anti-blocking agent is added to the pellets to prevent re-agglomerization of the modified polymer. When mixed with asphalt, a modified polymer asphalt is produced with enhanced Theological properties for high and low temperatures. | 07-29-2010 |

A partitioning or anti-blocking agent is added to the pellets to prevent re-agglomerization of the modified polymer. When mixed with asphalt for a sufficient period of time, a modified polymer asphalt is produced with enhanced rheological properties for high and low temperatures. | 02-27-2014 |

20130086371 | METHOD FOR DEVICE-LESS OPTION-ROM BIOS LOAD AND EXECUTION - An invention is provided for loading an Option-ROM BIOS into memory without the need of an associated hardware device, such as a PCI card. The invention includes loading code from a boot sector of a designated boot device into memory, wherein the code includes Option-ROM location data denoting a location of an Option-ROM BIOS. The Option-ROM BIOS then is loaded into memory utilizing the Option-ROM location data. As above, the Option-ROM BIOS includes MBR location data denoting a location of the MBR associated with the OS. Thus, the MBR can be loaded into memory utilizing the MBR location data in the Option-ROM BIOS and control can be transferred to the MBR. Thereafter, the OS system files are loaded into memory utilizing the MBR. | 04-04-2013 |
20140059291 | METHOD FOR PROTECTING STORAGE DEVICE DATA INTEGRITY IN AN EXTERNAL OPERATING ENVIRONMENT - An invention is provided for protecting the data integrity of a cached storage device in an alternate operating system (OS) environment. The invention includes replacing an actual partition table for a disk with a dummy partition table. The dummy partition table is designed to render data on the disk inaccessible when the dummy partition table is used by an OS to access the data. During operation, the data on the disk can be accessed using information based on the actual partition table. In response to receiving a request to disable caching, the dummy partition table on the disk is replaced with the actual partition table, thus rendering the data on the formally cached disk accessible in an alternate OS environment where appropriate caching software is not present. | 02-27-2014 |
20140372710 | SYSTEM AND METHOD FOR RECOVERING FROM AN UNEXPECTED SHUTDOWN IN A WRITE-BACK CACHING ENVIRONMENT - An invention is provided for recovering from an unexpected shutdown in a write-back caching environment. The invention includes storing a logical block address (LBA) mapping table on a caching device. The LBA mapping table maps logical block addresses of a target storage device to logical block addresses of the caching device. In addition, a LBA mapping table change log is maintained on the caching device. The LBA mapping table change log includes changes to the LBA mapping table since the LBA mapping table was last written to the caching device. During startup after an unexpected shutdown, the unexpected shutdown is detected using a header stored on a caching device. Among other data, the header includes an indicia indicating whether or not a clean shutdown occurred. When the unexpected shutdown is detected, a recovered LBA mapping table is generated based on the LBA mapping table, which is stored on the caching device, and the LBA mapping table change log. | 12-18-2014 |

20100162014 | Low power polling techniques - Techniques are described to provide the capability to halt execution of a thread by a processor and potentially lower power consumption of the processor while responding to events in a timely manner. An operating system provided system call allows for identification of events that cause the execution of the thread to resume. A processor core uses a signal mask and translation unit that monitors for the identified events. In the event an event is detected, the thread unhalts and determines a manner to process the event. | 06-24-2010 |
20100169501 | Massage communication techniques - A network protocol unit interface is described that uses a message engine to transfer contents of received network protocol units in message segments to a destination message engine. The network protocol unit interface uses a message engine to receive messages whose content is to be transmitted in network protocol units. A message engine transmits message segments to a destination message engine without the message engine transmitter and receiver sharing memory space. In addition, the transmitter message engine can transmit message segments to a receiver message engine by use of a virtual address associated with the receiver message and a queue identifier, as opposed to a memory address. | 07-01-2010 |
20100169528 | Interrupt technicques - Techniques are described that can be used by a message engine to notify a core or hardware thread of activity. For example, an inter-processor interrupt can be used to notify the core or hardware thread. The message engine may generate notifications in response to one or more message received from a transmitting message engine. Message engines may communicate without sharing memory space. | 07-01-2010 |
