Abstract: Abstract COMPOSITE ENERGY ABSORBING MATERIAL     A  method of making composite energy absorbing material containing frangible hollow shells, as of glass or ceramic material having predictable and uniform energy absorbing characteristics to be suitable for fabricating parts for the interior of automobiles.  In a first embodiment, a dry mix of heat expandable thermoplastic beads is formed having a uniform dispersal of shells and beads, with the mixture placed in a mold cavity and heat applied to expand the polymer beads and encapsultate the frangible shells in a matrix of the expandable polymer.  In a second embodiment, each of a series of sheets having a layer of shells one shell deep adhered thereto, and the sheets are laid an atop each other and adhered together to form a panel structure having a relatively ordered pattern of frangible shells dispersed therein to likewise have a uniform and predictable energy absorbing characteristic.

Title: Stabilization of monoclonal antibody for use in fluorescent polarization techniques
Inventor: BLONSKI DAVID R
IPC: G01N33/94
Filed: 1990-09-25
Abstract: Abstract of the Disclosure A method for determining ligands in a sample is disclosed. The method involves mixing with the sample in which the ligand is to be determined a tracer having the formula of Fig. 1 of the attached drawings or a biologically acceptable salt of such a tracer, a monoclonal antibody, and glycerol added as a part of a solution of the monoclonal antibody in which the glycerol is present in an amount sufficient to increase the stability of the monoclonal antibody in the solution, and then determining the amount of tracer bound to the antibody by fluorescence polarization techniques as a measure of the amount of ligand in the sample. In Fig. 1 of the drawings R is a ligand or analog thereof having at least one common epitope with a ligand to be determined so that the ligand to be determined and the ligand or    analog  thereof  of  the  tracer  are  both  specifically recognizable by a given antibody, and N is an integer from one to ten. The monoclonal antibody used is one which is capable of specifically recognizing both the ligand to be determined and the tracer.  Glycerol  is  used  in  the  monoclonal  antibody solution in an amount, usually from about 5 percent to about 20 percent, sufficient to increase the stability of the monoclonal antibody. The optimum glycerol concentration has been found to be about 10%.

Title: Combination of c5 to c6 isomerization and pressure swing adsorption
Inventor: ZARCHY ANDREW S
IPC: C10G45/58
Filed: 1991-11-28
Abstract: C5 and C6 hydrocarbons are isomerized in a process that combines a deisohexanizer with a PSA separation section to provide a product stream comprising highly branched hydrocarbons such as methylbutane and dimethylbutane. The process combines a methylpentane and normal hexane recycle stream, a normal pentane recycle stream and at least a portion of the and C6 hydrocarbons of the fresh feedstream to provide a combined feedstream that is charged to an isomerization zone. The effluent from the isomerization zone is stabilized and passed to a deisohexanizer. A sidecut stream carries the methylpentane and normal hexane recycle stream from the deisohexanizer. Hydrocarbons having a higher boiling point than the sidecut stream are withdrawn as a bottoms stream from the deisohexanizer. An overhead carries normal pentane, methylbutane and dimethylbutanes to the PSA separation section. An extract stream is recovered as the normal pentane recycle stream. The raffinate from the PSA provides a high octane isomerate stream comprising mainly methylpentane and dimethylbutanes.
