Abstract: A scalable computer system has an interconnect bus providing communication links among a host processor and one or more function-specific processors, including a network processor (NP) and a file storage processor (FSP). The host processor provides a single interface to network administrators for maintaining the system. A bi-endian conversion system is provided to minimize a need for translating between big and little endian data types generated by diverse processors. The NP shares a single memory image with other processors and has a buffer memory for buffering requests from the network interfaces. The buffer memory has one or more segments which are dynamically allocatable to different processors. The FSP has a metadata cache for maintaining information on data being cached in the NP buffer memory. The FSP also has a write cache for buffering file write operations directed at disks.

Abstract: A rotary kiln assembly comprising an inlet arrangement, a rotary kiln and an outlet arrangement. A seal arrangement is provided between the inlet arrangement and the rotary kiln and a seal arrangement is provided between the rotary kiln and the outlet arrangement. It is a problem with rotary kiln assemblies to remove the seals without relative movement of the rotary kiln or the inlet or outlet arrangements. At least one of the seal arrangements is made retractable in telescopic manner and the kiln assembly includes detachable spacing means such that the retractable seal arrangement can be removed from the kiln assembly as a unit without fouling or movement of the kiln or the inlet or outlet arrangements and hence without disturbing their alignment. The spacer means may be detachable only after retraction of the sealing arrangement and may be integral with a part of the sealing arrangement.

Abstract: A problem that can occur with a large rotary kiln assembly is that it can move out of position or seals can become defective, making an escape of materials possible. The present invention provides transducers (10, 15) for detecting movement of the rotary kiln itself or part of a seal assembly secured thereto relative to an inlet/outlet arrangement of the kiln assembly or a part of a seal arrangement secured thereto and also means whereby the condition of the seals can be monitored by following changes in the pressure or flow rate of a purge gas. If the rotary kiln (2) should move out of alignment, then corrective action can be taken. If the seals should leak, then they are changed. A record of kiln movement is provided and if movement is excessive, an alarm (20) is sounded.
