Title: Aluminum-base metal matrix composite
Inventor: ROHATGI PRADEEP K
IPC: C22C49/14
Filed: 1993-04-19
Abstract: The invention provides an aluminum-base composite material. The aluminum-base material contains a uniform distribution of carbide particles and lubricating phase particles such as carbon or graphite. The carbide particles increase hardness for improved wear resistance. The lubricating phase particles provide improved wear resistance and especially improve unlubricated wear resistance under increased loads. Finally, a dispersoid of nickel aluminide intermetallic phase may also be used to provide additional hardness and wear resistance. The composite is formed by introducing carbide particles and lubricating phase such as graphite into a molten aluminum alloy to neutralize buoyancy and to form an aluminum-base mixture. Mixing the aluminum-base mixture to uniformly distribute carbide and carbon particles throughout the molten aluminum. Carbide and carbon particles counteract each other to remain uniformly distributed throughout the aluminum-base alloy despite prolonged holding or cooling times.

Patent CA-2106280-A1 (CA)
Inventor: HUANG YENNUN
IPC: G06F11/07
Filed: 1993-09-15
Abstract: Techniques for fault-tolerant computing without fault-tolerant hardware or operating systems. The techniques employ a monitor daemon which is implemented as one or more user processes and a fault-tolerant library which can be bound into application programs. A user process is made fault tolerant by registering it with the monitor daemon. The degree of fault tolerance can be controlled by means of the fault-tolerant library. Included in the fault-tolerant library are functions which define portions of a user process's memory as critical memory, which copy the critical memory to persistent storage, and which restore the critical memory from persistent storage. The monitor daemon monitors fault-tolerant processes, and when such a process hangs or crashes, the daemon restarts it. When the techniques are employed in a mufti-node system, the monitor on each node monitors one other node in addition to the processes in its own node. In addition, the monitor may maintain copies of the state of fault- tolerant processes running at least on the monitored node. When the monitored node fails, the monitor starts the processes from the monitored node for which the monitor has state on its own node. When a node leaves or rejoins the system, the relationship between monitored and monitoring nodes is automatically reconfigured.

Title: Developer-circulating method in flexographic printing plate-making process and apparatus for carrying out developer-circulating method
Inventor: MURAMOTO HISAICHI
IPC: G03F7/30
Filed: 1993-10-27
Abstract: The present invention is directed to a developer-circulating method and an apparatus for carrying out the method in making a flexographic printing plate which prevents dissolved chemical substances from adversely affecting human bodies and has excellent safety; is capable of preventing an increase of the developer viscosity; and is capable of effectively preventing the dissolved chemical substance from adhering to the apparatus, thus preventing the life of the apparatus from being reduced and collecting the dissolved chemical substance in a short period of time and which is superior in operation efficiency, work efficiency, and treating efficiency.  The solid content of the liquid containing resin component which has eluted from the flexographic printing plates and is dispersed in the developer is flocculated with a flocculating agent, and the liquid containing the flocculated solid content is separated into liquid and solid contents.  The solid content is discharged and the liquid is re-utilized as a developer.  A pH-adjustment may be performed in addition to the flocculation.          The pH-adjustment may be carried out after the developer is separated into solid content and liquid, without performing the flocculating process.
