Abstract: A process for preparing a tin-containing zeolitic material having a BEA framework structure comprising providing a zeolitic material having a BEA framework structure having vacant tetrahedral framework sites, providing a tin-ion source in solid form, incorporating tin into the zeolitic material via solid-state ion exchange, calcining the zeolitic material, and treating the calcined zeolitic material with an aqueous solution having a pH of at most 5.

Abstract: A human &mgr; opiate receptor cDNA has been identified from a cerebral cortical CDNA library using sequences from the rat &mgr; opiate receptor CDNA. The human &mgr; opiate receptor (h&mgr;OR1) shares 95% amino acid identity with the rat sequence. The expressed &mgr;OR1 recognizes tested opiate drugs and opioid peptides in a sodium- and GTP-sensitive fashion with affinities virtually identical to those displayed by the rat &mgr; opiate receptor. Effects on cyclic AMP are similar to those noted for the rat &mgr; opiate receptor. Overlapping genomic clones spanning 50 kilobasepairs and hybridizing with the h&mgr;OR1 cDNA contains exon sequences encoding the entire open reading frame of the human A opiate receptor are described. Analysis of hybridization to DNA prepared from human rodent hybrid cell lines and chromosomal in situ hybridization studies indicate localization to 6q24-25. An MspI polymorphism, producing a 3.

Abstract: A method for measuring changes in the amount of solids or liquids entrained in vapor in a container includes introducing a first vapor purge stream into a first sensor, introducing a second vapor purge stream into a second sensor located at a different level from the first sensor, and measuring the relative pressure between the sensors as indicative of changes in the amount of entrained solids or liquids.

Abstract: A method for determining the specific gravity of a liquid includes introducing a purge stream of a reference liquid into a column and introducing a first vapor purge stream into a first sensor located below the level of the reference liquid. Then a second vapor purge stream is introduced into a second sensor located below the level of the reference liquid sensor and a measurement of the difference in pressure between the two sensors is indicative of the specific gravity of the liquid.

Abstract: A method for measuring the density of a vapor includes continuously introducing the vapor into the inlet of a vertical zone at a rate sufficient to maintain the zone completely filled with the vapor, and measuring the pressure at the lower portion of the zone relative to a reference pressure.

Abstract: An improved apparatus for distributing particulate material, e.g., comprising catalyst particles, over a zone, e.g.
