Abstract: A display system can accommodate a number of products. The system includes one or more modules. Each module may be mounted on a support wall and includes back and shelf portions. Advantageously, a number of modules are arranged in a number of rows, one row above another. A number of dividers are removably secured to at least one of the walls and may be moved in stepwise or continuous fashion to separate groups of the products within each row. Various of the modules may include hook bars secured to the back wall portions for hanging certain of the products and/or space thieves removably secured to the shelf portions for forwardly offsetting stacked or hung products.

Abstract: A semiconductor wafer provided with a thermosetting porous insulating film, wherein the insulating film is made porous, cured and polymerized on the wafer. The film is characterized by a very low dielectric constant based on its constituency and porosity, the latter property of which is caused by the inclusion of liquid or supercritical carbon dioxide in the polymeric reaction mixture.

Abstract: An interconnect structure for a semiconductor device includes an organic, low dielectric constant (low-k) dielectric layer formed over a lower metallization level. A via formed is within the low-k dielectric layer, the via connecting a lower metallization line formed in the lower metallization level with an upper metallization line formed in an upper metallization level. The via is surrounded by a structural collar selected from a material having a coefficient of thermal expansion (CTE) so as to protect the via from shearing forces following a thermal expansion of the low-k dielectric layer.

Abstract: An improved thermal phase separation unit separates contaminants from a contaminated substrate. The improved thermal phase separation unit includes an enclosure arranged to withstand temperatures created by a combustion system, an essentially air-tight processing chamber supported within the enclosure by support columns connected between the processing chamber and a bottom of the enclosure, a heat shield disposed between the processing chamber and the bottom of the enclosure, and a vapor handling system arranged to remove vapor from the processing chamber. The combustion system heats the processing chamber, and, in turn, indirectly heats contaminated substrate being processed in the processing chamber so as to volatize contaminants in the contaminated substrate to vapor that is subsequently removed by the vapor handling system.

Abstract: A new class of fluorinated arylacetylene compounds useful as monomers in the formation of polymers having low dielectric constant. These polymers, which are the reaction products of one of the fluorinated arylacetylene compounds, a diphenyl oxide biscyclopentadienone and, optionally, 1,3,5-tris(phenylacetylene)benzene, are useful in insulating microelectric device.

Abstract: Novel growth hormone releasing factor analogs are presented having a sequence of from about twenty-nine (29) to about forty-four (44) amino acids (SEQ ID NO: 6) wherein Xaa at position 1 is His, 3-MeHis, desNH.sub.2 His, Tyr, or desNH.sub.2 Tyr; Xaa at position 2 is Val, Leu, lie, Ala, D-Ala, N-Methyl-D-Ala, Gly, NIe, or Nval; Xaa at position 8 is Gln, Ser, or Thr; Xaa at position 15 is Ala or Leu; Xaa at position 27 is Met, Nle or Leu; Xaa at position 28 is Ser or Asn; Xaa at position 29 is an amino acid residue sequence (SEQ ID NO: 7) or fragments thereof where the fragment is reduced in number by one to fifteen amino acid residues from the carboxyl-terminus, where the carboxyl terminus can be the free carboxylic acid or the corresponding amide, and the pharmaceutically acceptable acid or base addition salts thereof.

Abstract: Novel growth hormone releasing factor analogs are presented having the formula: ##STR1## wherein R.sub.1 is His, 3-MeHis, desNH.sub.2 His, Tyr, or desNH.sub.2 Tyr; R.sub.2 is Val, Leu, or Ile; R.sub.3 is Ala; R.sub.4 is Met, Leu, Ile, or Nle; R.sub.5 is Ser or Asn; R.sub.6 is an amino acid residue sequence selected from Arg-Gln-Gln-Gly-Glu-Ser-Asn-Gln-Glu-Arg-Gly-Ala-Arg-Ala-Arg-Leu or fragments thereof where the fragment is reduced in number by one to fifteen amino acid residues from the amino acid residue which carries the substituent X; and X is either OH or NH.sub.2, and the pharmaceutically acceptable acid or base addition salts thereof. The novel growth hormone releasing factor analogs demonstrate enhanced potency for the released growth hormone, have enhanced enzymatic stability, and can be administered to a subject having a deficiency of growth hormone or for improvement of growth performance in livestock.

Abstract: An image reader guide for hand-held image readers for the transfer of printed or textual matter to a data storage device whereby the hand-scanner is repeatedly, selectively aligned with the printed matter through the use of a U-shaped planar guide and planar template tray which interlock with each other to provide a manual guide for the use of the hand scanner in positioning the hand scanner over the printed matter for reading and transfer to the data storage source.

Abstract: An apparatus for proportioning and mixing liquids having a plurality of containers each containing a respective said liquid, a plurality of compression chambers individual to said containers connected in fluid communication with their respective containers, pistons individually mounted in the chambers for corresponding movement therein, a mixing head having an outlet and inlets individually connected to the chambers, and a system for sequentially pressurizing the containers to deliver their respective liquids to their respective chambers, and subsequently correspondingly pressurizing the pistons to deliver in proportioned amounts the liquids therein to their respective inlets of the mixing head.

Abstract: A sensitive immunoassay for acetylcholine is described. To prepare the acetylcholine selective antiserum, an antigen is made comprising 6-aminocaproic acid (2-trimethylaminoethyl) ester covalently bonded to an immunogenic carrier material through a peptide bond formed from said 6-amino group and carboxyl groups contained in said immunogenic carrier material and the antigen is injected into a suitable host animal to elicit the desired antiserum.

Abstract: D,L-3,4-dehydroproline is resolved in high optical yield by conversion to its N-protected derivative, treatment with R(+)alpha-methyl-p-nitrobenzylamine to form the diastereomeric salts, fractional crystallization, decomposition of the L-R salt and regeneration of the secondary amine group. The product L-3,4-dehydroproline obtained in extremely high optical purity is useful as an inhibitor of collagen synthesis.

Preferred amino acid residues for this purpose include 3,4-dehydroproline (.DELTA..sup.3 -proline) and trans-4,5-dehydrolysine (.DELTA..sup.4 -lysine).

Abstract: A mixer for particulate solid material including a hollow casing of polygonal e.g. square or triangular cross-section, the casing having two or more materials fed to it and having disposed therein at least one set of partitions which divide the casing up into a plurality of channels also of polygonal cross-section, the shape of the channels generally being the same as the shape of the casing, some, but not all, of the channels, having a redistributor therein which will allow the material flowing therethrough to be redistributed across the cross-section of that channel. The redistributor disclosed is a generally helical element which is shaped so as to fill the polygonal section of the channel into which it is fitted.
