Title: Linear ethylene interpolymer blends of interpolymers having narrow molecular weight and composition distributions.
Inventor: STEHLING FERDINAND CHRISTIAN
IPC: C08F210/16
Filed: 1989-09-28
Abstract: Linear ethylene interpolymer blends are disclosed. The blends are made from components having a narrow molecular weight distribution (e.g. Mw/Mn  </=  3) and a narrow composition distribution (e.g. CDBI > 50 %). The blend components in a blend can all have the same molecular weight but different comonomer contents, the same comonomer content but different molecular weights, or comonomer contents which increase with molecular weight. The blends have either Mw/Mn > 3 or CDBI < 50 %, or both, and can be multimodal with respect to either or both molecular weight and/or comonomer content. The blends are generally free of blend components having both a higher average molecular weight and a lower average comonomer content than another blend component. The blends can have improved mechanical, physical and/or chemical properties.

Abstract: The image is divided into several portions and each image portion is examined to determine therein, in the presence of a series of images 20, 21, 22 following one another over time, a motion vector V. 
<??>When it is desired to create intermediate images 23, 24 between the images available initially, it may be that there are several different vectors all yielding equivalent results for certain image portions. To remove the ambiguity, for each equivalent motion vector 16 able to be used to create an intermediate image 24, the position 17 is determined at which the relevant image portion 25 would be located in an earlier image 23 if the said motion vector were applied to this image portion, and on each occasion the difference is calculated between the motion vector used to arrive at the said position 17 and the motion vector which had been determined for this position in the earlier image 23. The motion vector selected is then the one from those for which this difference is for example less than a specified threshold. 
<??>Application: high definition television or ordinary transmission-reception systems, in image recording systems, for example those using a laser-read disc, and in general in digital image processing systems.

Abstract: In a steam generator utilized with a liquid sodium cooled nuclear reactor to which it is coupled by an IHTS (intermediate heat transport system), provision is made to vent the violent sodium water reaction emanating from a tube rupture casualty. In the preferred embodiment, the steam generator is of the type combining a sodium expansion volume (C), an electromagnetic pump (Q′) for circulating sodium, and a large number of helically coiled tubes (78) for generating steam. The invention is also applicable to helical coiled tube steam generators having other types of internal and/or external sodium pumps. The steam generator includes a sodium plenum (64) at the bottom thereof containing a conventional rupture disk (D) for venting sodium, steam, and reaction products including hydrogen immediately upon a tube rupture casualty. The invention includes providing an alternate concentric flow path (63) interior to the steam generator and parallel to the tube bundle. This alternate concentric flow path extends from the upper portion of the steam generator down into the lower head or plenum adjacent to the pressure relief diaphragm. This alternate path is partially filled with sodium (80) during normal reactor operation. In the event of a tube bundle break, the alternative flow path dumps its sodium through the conventional rupture disk and then provides an immediate alternate pressure release path in parallel with the tube bundle for steam and water flow from the tube rupture site to the rupture disk. This parallel flow path reduces the pressure differential from the water/­steam flow through the tube bundle such that water/steam does not flow back through the IHTS (18/20) to the IHX intermediate heat exchanger in the reactor, where it would react with residual sodium and potentially damage the IHX tube bundle which is part of the reactor primary containment barrier.

Abstract: The sample liquids analysis system includes a probe which is automatically operable to successively aspirate sample liquids and reagent and/or other sample liquids processing liquids and to dispense the same in turn into sample liquids analysis apparatus for automatic, successive sample liquids analyses. Isolation liquid supply apparatus are operatively associated with the sample liquids aspirating the dispensing probe and operate to introduce an isolation liquid which is immiscible with the sample liquids and which selectively wets the probe to the substantial exclusion of the sample liquids, to the probe to, in combination with operatively associated rinse liquid supply apparatus which operate to fill the probe with a rinse liquid between successive sample liquids aspirations, reduce sample liquids carryover to ultra low levels. The sample liquids aspirating and dispensing probe are operated by the rinse liquid supply apparatus; and comprise a probe body member, and an active probe component operatively connected thereto by a readily disconnectable connector, thus making possible the ready and convenient replacement of the active probe component without adverse effect upon the essential configuration and/or operational characteristics of the rinse liquid supply apparatus, and thereby upon the overall performance of the sample liquids analysis system. The configuration of the probe operates to reduce sample liquids flow velocity in the active probe component, thereby further reducing sample liquids carryover.

Abstract: Pentapeptides having the formula H-Asp-Ser-C-Pro-Arg-OH, where Asp, Ser, Pro and Arg may have L- or D-configuration, and C denotes Asp or Asn in L or D configuration, are synthesized by reacting in an aqueous medium Y2-Pro-OH, wherein Y2 is a protective group, with Arg-Ro, wherein Ro is OH or is as defined below for R1 below, to form Y2-Pro-Arg-Ro, which is deprotected, if necessary under conversion to Pro-Arg-R1, wherein R1 is an enzymatically cleavable  alpha -carboxy substituting group selected from esters, amides, anilides, hydrazides or L-amino acid esters, and thereafter reacting Y3-C(Z3)-OH with Pro-Arg-R1 to form Y3-C(Z3)-Pro-Arg-R1, which is deprotected to C-Pro-Arg-R1, and then reacting Y4-Ser-OH with C-Pro-Arg-R1 to form Y4-Ser-C-Pro-Arg-R1, which is deprotected to Ser-C-Pro-Arg-R1, and reacting Y5-Asp(Z5)-OH with Ser-C-Pro-Arg-R1 to form Y5-Asp(Z5)-Ser-C-Pro-Arg-R1, which is deprotected to the intermediate Asp-Ser-C-Pro-Arg-R1, and finally removing the group R1 with an enzyme, preferably trypsin to form Asp-Ser-C-Pro-Arg, or removing R1 from Y5-Asp(Z5)-Ser-C-Pro-Arg-R1 before deprotection to Asp-Ser-C-Pro-Arg-OH. The groups Y2, Y3, Y4, Y5, Z3 and Z5 are protective groups which apart from Y2 are removable by catalytic hydrogenation. The employed synthesis strategy based on the combination hydrogenation/enzyme, both proceeding under mild conditions, leads to the peptides, in particular HEPP, in good yield without risk of formation of  beta -aspartyl peptides and cleavage of Asp-Pro bonds.
