Title: Detection of complementary nucleotide sequences
Inventor: EISENBEIS SCOTT J
IPC: C12Q1/68
Filed: 1992-08-12
Granted: 1998-05-19
Abstract: The invention relates to a method for detection of a specific nucleic acid sequence which comprises forming a reaction mixture by combining (1) a sample suspected of containing a nucleic acid; (2) a probe/enzyme donor polypeptide conjugate comprising (a) an enzyme donor polypeptide sequence comprising a .beta.-galactosidase fragment; and (b) a single-stranded oligonucleotide sequence attached to (a) and capable of hybridizing with said nucleic acid; (3) an enzyme acceptor polypeptide capable of forming an active enzyme upon complementation with said enzyme donor-fragment; and (4) a substrate for .beta.-galactosidase; and detecting hybridization of said probe/enzyme donor conjugate to said sample nucleic acid to form a double strand-specific sequence by determining theamount or rate of enzyme activity on said substrate in said reaction mixture. The method can also include a "proof reading" function by incubating the hybridized probe with at least one double-strand specific, sequence-specific restriction endonuclease.   Novel kits for use in carrying out the method are also included.

Granted: 2000-03-14
Abstract: Dispositif de retenue de poinçon (20) amélioré dans lequel une plaque d'appui (24) s'étend sur une surface relativement grande pour dissiper la force émanant d'un poinçon (64). Un corps de retenue (22) et la plaque d'appui sont reliés l'un à l'autre de façon permanente et comportent des passages (38, 40, 42, 44 et 46) qui sont finalement meulés après avoir été fixés à demeure. Ce dispositif permet d'avoir des passages dans la plaque d'appui et dans le corps de retenue bien alignés durant la constitution du dispositif de retenue de poinçon. Comme la plaque d'appui dissipe la force sur une surface relativement grande, le dispositif de retenue de poinçon peut être utilisé dans des conditions plus sévères que les dispositifs de retenue de poinçon de l'art antérieur. Un passage de ressort (56) est fermé par un élément étanche (79) inséré dans la plaque d'appui, ce qui permet l'utilisation de ressorts standard (82).

Title: Sequence for separating propylene from cracked gases
Inventor: STRACK ROBERT DAVID
IPC: C10G70/04
Filed: 1991-10-18
Granted: 1996-10-15
Abstract: A process sequence for treating cracked gases of heavy feedstocks which preferentially produces propylene to the exclusion of propane, butanes and butenes. The process eliminates the need for a depropanizer with the attendant savings in capital and op-erating costs. In lieu of a conventional C3 splitter, the process features a depropylenizer, i.e. a distillation tower designed to sepa-rate propylene from propane, butanes and butenes. A hydrogenation unit to eliminate contaminants can be placed upstream of the depropylenizer or the depropylenizer can be split into two sections with the hydrogenation unit located between the two sec-tions.
