Abstract: A prosthetic nucleus for a vertebral disc is made of a hydrogel material. The hydrogel prosthetic nucleus has a shape generally conforming to the natural nucleus pulposus. The hydrogel has a water content of at least 30% and has a compressive strength of 4MNm<-><2> or greater. When the hydrogel material is dehydrated, it has a dimension of less than half of that of the hydrated hydrogel nucleus. The prosthetic nucleus may be formed of two or more pieces of hydrogel material which pieces, when combined, have a shape generally conforming to the natural nucleus. The prosthetic nucleus for implantation in the disc space after removal of a damaged or degenerated nucleus may also be formed from a multiplicity of hydrogel beads having a water content of at least 30%. The beads are covered by a semi-permeable membrane. The membrane has porosity less than the size of the beads to thereby retain the beads therein but permit fluids to flow in and out of the prosthetic nucleus. <IMAGE>

Abstract: A method and apparatus for an FCC process uses dissipator plates at the outlet of a disengaging vessel to provide a quick separation of catalyst from product vapors and to prevent reentrainment of catalyst by stripping gas which is passed into the disengaging vessel. The process and apparatus use a riser for the conversion of an FCC feedstock and direct the effluent from the riser directly into a disengaging vessel to separate catalyst from the product vapors. Catalyst is directed downwardly out of the outlet of the disengaging vessel and through a series of dissipator plates that eliminate the tangential velocity that would be otherwise introduced by the vortex and would lead to reentrainment of catalyst. The dissipator plates are located in a stripping vessel positioned immediately below the disengaging vessel outlet to receive catalyst as it leaves the disengaging vessel. <IMAGE>

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 multi-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.

Date Dec. 9, 1993In accordance with the present invention, it has been discovered that a major reason for the failure to achieve successful in vivo transplantation in large mammalian species has been flaws associated with the design of microcapsules taught in the prior art, flaws in the method of making such microcapsules, and a lack of tests to determine if a given microcapsule will be successful. In accordance with the present invention, a number of functional properties which must be met by a microcapsule in order to achieve successful in vivo transplantation in large animal models have been identified. These properties include (i) a mechanically stable capsule core, (ii) a mechanically strong capsule membrane (i.e., the membrane must be of sufficient strength to prevent capsule disruption), (iii) the absence of excess exposed positively-charged PLL (which leads to fibrosis), and (iv) an adequate level of diffusion of the entrapped biologically active material out of the capsule.

Abstract: Luggage cases, especially if they are large and bulky, usually have wheels and glides or legs to hold the case upright when loaded and permit the case to be pulled or wheeled. These same large cases present a large volume-an advantage when actually being used to carry clothing. However, this large volume is a disadvantage during packaging, storage and shipping after manufacture, such as between the factory and the store where it is sold. This large volume is a disadvantage also when the case is being stored by the owner between trips. Shown here is a case (10) with easily removable wheels (11) and feet (13). These external fittings attach to the outside of the luggage shell and have a projection (92) which extends to an aperture (90) in the wall of the case shell to the inside of the case. A manually releasable latch (96), such as a clip, engages and disengages this projection from the inside of the case to mount the wheel and leg to the outside of the case. This attaching system also acts as an anchoring device (114) for the straps (116) normally used to hold and arrange clothing when packed inside the assembled case. This external fitment system is especially useful when the two shells (12) and (14) of the case are stored one within the other during shipping by the manufacturer and storage by the consumer.

Abstract: Decomposition of ozone in a microwave discharge cavity leads to formation of highly energetic excited states of atomic oxygen which can efficiently oxidize materials at a temperature far less than that needed for purely thermal oxidation. This technique can be applied to formation of films of silica at the surface of silicon and silicon carbide while maintaining quite moderate surface temperatures, often under 100 DEG  C. The technique can be used generally in a process to oxidize materials whose oxidation requires a standard free energy change of less than about +636 kJ/mol.
