摘要:
A process for preparing ethylbenzene from benzene and ethylene in which a vapor phase alkylation reactor is combined with a liquid phase transalkylation reactor wherein the xylenes content of the ethylbenzene product is less than 700 wppm. Also disclosed are ethylbenzene processes in which a series-arranged or combined vapor phase alkylation/transalkylation reaction zone is retrofitted to have a vapor phase alkylation reactor and a liquid phase transalkylation reactor, and in which a parallel-arranged vapor phase alkylation reactor and vapor phase transalkylation reactor is retrofitted to have a vapor phase alkylation reactor and liquid phase transalkylation reactor. An apparatus for the practice of the ethylbenzene process of this invention is disclosed.

Wall mount assemblies operable to be mounted to a building are described. The wall mount assemblies include a base having a front surface and a rear surface and having a wall extending about an outer periphery and inwardly from the rear surface. The base also includes at least one edge recessed rearwardly from the front surface defining a recessed portion therein. The edge of the recessed portion also defines mounting apertures and/or mounting holes spaced about the recessed portion. An annular flange extends rearwardly from the recessed portion. A cover member mounts to either one of the mounting apertures and the mounting holes for creating an aesthetic appearance.
摘要:
An altered antibody chain is produced in which the CDR's of the variable domain of the chain are derived from a first mammalian species. The framework-encoding regions of DNA encoding the variable domain of the first species are mutated so that the mutated framework-encoding regions encode a framework derived from a second different mammalian species. The or each constant domain of the antibody chain, if present, are also derived from the second mammalian species. An antibody which is capable of binding to human CD4 antigen is also provided together with a pharmaceutical composition comprising the antibody.
摘要:
A processing node that is integrated onto a single integrated circuit chip includes a first processor core and a second processor core. The processing node also includes an operating system executing on either of the first processor core and the second processor core. The operating system may monitor a current utilization of the first processor core and the second processor core. The operating system may cause the first processor core to operate at performance level that is lower than a system maximum performance level and the second processor core to operate at performance level that is higher than the system maximum performance level in response to detecting the first processor core operating below a utilization threshold.

A new and improved exercise treadmill may include a frame having a first end and a second end, wherein the second end is parallel to the first end. Two side rails interconnect the first and second end. The treadmill may further comprise a motor in order to drive a belt, which is trained over a front roller and a rear roller. A deck is positioned underneath the belt in order to support the user. At the first end of the treadmill, first and second arms extend upwardly and terminate in the protective shroud. The shroud may further comprise a console which contains push buttons for operating various programs while using the treadmill. The treadmill may further comprise two handles, which extend parallel to the deck. The treadmill may comprise a console that may have programs which may be started by pushing one button. It may also comprise a belt tensioning device, which provides a visual indicator so that the rear roller may be moved on each end in equal distance relative to the front roller. Another feature of the invention is a slot between the side rails and the frame so that an extended member can be inserted therein to lubricate the belt.

Novel aglycosylated antibodies having a binding affinity for the CD3 antigen complex are of value for use in therapy, particularly in immunosuppression.
摘要:
In one embodiment, a system comprises a first processor core and a second processor core. The first processor core is configured to communicate an address range indication identifying an address range that the first processor core is monitoring for an update. The first processor core is configured to communicate the address range indication responsive to executing a first instruction defined to cause the first processor core to monitor the address range. Coupled to receive the address range indication, the second processor core is configured, responsive to executing a store operation that updates at least one byte in the address range, to signal the first processing core. Coupled to receive the signal from the second processor core, the first processor core is configured to exit a first state in which the first processor core is awaiting the update in the address range responsive to the signal.
