Abstract: Abstract:     The invention provides a hollow fiber membrane suitable for dialysis made of a cellulose ester.  The hollow fiber membrane has a membrane thickness of less than 20µ, and a yield strength Sb (g/filament) after being heat-treated at 80°C for 20 hours which satisfies the following formula (I):             0.90 < Sb/Sa < 1.10        (I) wherein Sa is the yield strength (g/filament) of the hollow fiber membrane measured before the heat treatment.  The present invention further provides a method for producing the hollow fiber membrane which comprises extruding a spinning solution of a cellulose ester through circular slits around an inner tube of a spinneret while simultaneously extruding a core solution through the inner tube of the spinneret, passing the spinning solution extruded from the circular slits through a gaseous atmosphere, introducing the same into an aqueous coagulation bath, washing the coagulated hollow fibers, passing the fibers through a glycerin bath, drying the fibres, reeling the fibres onto a bobbin and then heat treating the reeled fibers.  The membrane is suitable for the dialysis of body liquids, and particularly for the dialysis of blood, because it has good dialysis performance while maintaining good storage stability and good UFR retention during storage and during hemodialysis.

Abstract: Abstract of the Disclosure A packet switching architecture in which switching network nodes automatically determine alternate routes through a switching network so as to increase reliability and distribute traffic.  The switching network comprises stages of distribution and routing nodes.  The routing nodes are responsive to physical addresses associated with the packets to communicate those packets to address designated downstream nodes.  The distribution switching nodes statistically communicate packets to downstream switching nodes on the basis of an alternate routing algorithm and availability of downstream nodes.  The initial network stages are alternate distribution and routing stages followed by only routing stages for the remaining stages of the network.  Both the routing and the distributing nodes are identical in design and are responsive to an input signal from the network to assume either routing or distributing functions.

Abstract: ABSTRACT OF THE DISCLOSURE           A unitary thick walled spacer supports an anchor rod for engagement in an expansion body.  The tubular spacer has a first part of greater diameter than its remaining part, with the latter part in sliding fit engagement in the expansion body and the first part abutting, at its free end, a washer and the head of an anchor rod.  The annular rim formed between the parts of the spacer is arranged, prior to use, a distance X from the expansion body.  As clamping down is performed in a receiving socket,  the spacer part slides inside the expansion sleeve so progressively closing the gap X.  The arrangement may be so designed that, in any particular application, the rim never comes into contact with the expansion body (or at the most just does so), so avoiding uselessly and detrimentally loading on the spacer.

Abstract: A COOPERATIVE MEMORY HIERARCHY                   ABSTRACT       A prefetching mechanism for a memory hierarchy which includes at least two levels of storage, with L1 being a high-speed low-capacity memory, and L2 being a low-speed high-capacity memory, with the units of L2 and L1 being blocks and sub-blocks respectively, with each block containing several sub-blocks in consecutive addresses.  Each sub-block is provided an additional bit, called a r-bit, which indicates that the sub-block has been previously stored in L1 when the bit is 1, and has not been previously stored in L1 when the bit is 0.  Initially when a block is loaded into L2 each of the r-bits in the sub-block are set to 0.  When a sub-block is transferred from L1 to L2, its r-bit is then set to 1 in the L2 block, to indicate its previous storage in L1.  When the CPU references a given sub-block which is not present in L1, and has to be fetched from L2 to L1, the remaining sub-blocks in this block having r-bits set to 1 are prefetched to L1.  This prefetching of the other sub-blocks having r-bits set to 1 results in a more efficient utilization of the L1 storage capacity and results in a higher hit ratio.
