Title: Degradation de nitramines cycliques
Inventor: HAWARI JALAL
IPC: A62D3/176
Filed: 2002-11-27
Abstract: La présente invention concerne un procédé de dégradation de nitramines, et plus particulièrement des explosifs que sont les RDX, HMX, CL20 et tétryle. Ces nitramines sont chimiquement attaquables par voie chimique, biochimique ou biologique. L'invention convient à la dégradation de tels composés explosifs susceptibles d'être présents dans le sol. On peut attaquer les nitramines cycliques au niveau des liaisons de façon à provoquer un clivage du cycle qui, en présence d'eau, peut aboutir à une décomposition hydrolytique puis à une minéralisation. Pour éviter que la réaction de décomposition ne subisse une réduction séquentielle donnant le dérivé nitroso correspondant, la nitrosation étant la réduction du -N02 en -NO), on peut emprunter deux voies: (a) attaque d'une liaison -N-N02 (dénitration) suivie d'une hydratation ou (b) attaque d'une liaison CH2 (α-hydroxylation) donnant un carbinol instable avant clivage et décomposition. L'invention convient particulièrement à la réhabilitation de sols et d'eaux contaminés par ces explosifs.

Abstract: A method of manufacturing a seamless tube formed of a titanium material, such as pure titanium or titanium alloys, by the use of the Mannesmann's method.  At first, an ingot formed of the titanium material is processed under the con-ditions that a heating temperature is 850 to 1,250 °C, the final temperature being 600 to 1,100 °C, and a working degree being 50 % or more to be turned into a solid billet.          The resulting solid billet is subjected to a piercing within a temperature range of .beta. transus - 100 to 1,250 °C to be turned into a hollow piece.  In this piercing process, in-clined rolls of a piercer are descaled.  The resulting hol-low piece is in case of need regulated a size thereof sub-jected to an elongating to be turned into a hollow shell.          Subsequently, the resulting hollow shell is subjected to a reducing (reducing conditions: temperature at an inlet side of the mill is 600 to 1,100 °C and a reduction of outside diameter is 80 % or more) by means of a reducer mill or to a sizing (sizing conditions: temperature at an inlet side of the mill is 550 to 1,150 °C and a reduction of outside diameter is 3 to 15 %) by means of a sizer mill.
Patent CA-2003348-A1 (CA)
IPC: E21B33/043
Filed: 1989-11-20
Abstract: A tool for setting or retrieving a packoff between the   casing hanger   and   the   wellhead   utilizes differential area pistons.   The tool has a mandrel which connects to a string of drill pipe.  The mandrel carries a body and is axially movable relative to the body.  A sleeve is carried by the body for connection to the packoff.  A sleeve piston is carried by the body for relative movement relative to the body.  A mandrel piston is carried by the mandrel for movement with the mandrel.  Passages in the body communicate the mandrel piston  with    the  sleeve  piston  and  contain  an incompressible fluid.   Axial movement of the mandrel causes the pressure to increase to drive the sleeve piston downward to  set  the  packoff,  or  in  another embodiment, upward to retrieve the packoff.

Title: Cloning and expression of simian transforming growth factor-beta 1
Inventor: PURCHIO ANTHONY F
IPC: C12N15/12
Filed: 1989-11-24
Abstract: ABSTRACT Recombinant transforming growth factor-.beta.1 (TGF-.beta.1) is expressed to high levels in Chinese hamster ovary (CHO) cells using dihydrofolate reductase (dhfr) gene amplification. The expression plasmid was derived from the pSV2 vectors and contained, in tandem, the simian TGF-.beta.1 and mouse dhfr cDNAs. Transcription of both cDNAs was controlled by the SV40 early promoter. Stepwise selection of transfected CHO cells in increasing concentrations of methotrexate yielded cell lines expressing amplified TGF-.beta.1 nucleic acid sequences. The expression plasmid DNA was amplified greater than 35-fold in one of the methotrexate selected transfectants. The major proteins secreted by these cells consisted of latent TGF-.beta.1 and TGF-.beta.1 precursor polypeptides as judged by immunoblots using site-specific anti-peptide antibodies derived from various regions of the TGF-.beta.1 precursor. Levels of recombinant TGF-.beta.1 protein secreted by these cells approached 30 ug/24 hour/107 cells. Expression vectors encoding TGF-.beta.1 precursor variants which direct the synthesis and secretion of TGF-.beta.1 in transfected mammalian cells are also described.

Abstract: A process for preparing a microwave cooked pasta product is disclosed. The process comprises the steps of (a) combining flour, egg whites, water, and optionally whole eggs, and a dibasic or tribasic acid derivative such as a tricarboxylic acid derivative, to form a paste, (b) drying the paste to produce pasta at drying temperatures of 100 DEG  to 130 DEG F, (c) optionally soaking the pasta in hot or cold temperature liquid for a period of time sufficient to at least partially hydrate the paste, (d) heating the pasta for a period of time sufficient to cook the pasta, e.g. about 1 to 2 minutes.
