Patent NO-331640-B1 (NO)
Inventor: BAYER KARL
IPC: C12N15/09
Filed: 2003-04-03
Abstract: In an expression vector having a ColE1 replication system, the homology of the RNAI and RNAII of the ColE1 origin of replication to uncharged tRNAs is modified by mutations in the coding region of the RNAI gene and corresponding mutations in the RNAII gene. The mutation results in one or more base exchanges in loop 1 and/or loop 2 and/or loop 3 of RNAI and RNAII. In methods using this vector for producing recombinant proteins, plasmid copy number is stably maintained.

Abstract: A breath actuated dispenser there-shown has a generally L-shaped hollow body 1 with a mouthpiece 2. An aerosol drug can 3 is mounted in the body. The can has a dispensing spout 4, which engages a receptor moulding 5 incorporating a living hinge 11, a movable outlet member 8 and a kink valve 9. A flap member 31 is pivotally mounted between the can and the receptor moulding. Breathing in through the dispenser by the patient will cause the flap to be drawn down against its spring 34. The outlet member is then tipped down by the spring 37 to point out of the mouthpiece 2, whence the dose is dispensed by opening of the kink valve.

Title: Epoxy-polysiloxane polymer composition
Inventor: MOWRER NORMAN R
IPC: C08G59/14
Filed: 1997-05-06
Abstract: Epoxy-polysiloxane polymer compositions of this invention are prepared by combining a resin component with a hardener component. The resin component comprises a non-aromatic epoxy resin ingredient and a polysiloxyne ingredient. The hardener component comprises an amine and optionally an organotin catalyst. The composition can also include aggregates, pigments and other additives depending on the particular end user. The composition is prepared using a sufficient amount of water to promote hydrolysis of the polysiloxane and the polycondensation of the silanols produced by such hydrolysis. In its cured form, the epoxy-polysiloxane composition exists as a uniformly dispersed arrangement of linear epoxy chain fragments that are cross-linked with a continuous polysiloxane polymer chain, thereby forming a non-interpenetrating polymer network chemical structure that has substantial advantages over conventional epoxy systems. Protective coatings forming from such compositions exhibit excellent weatherability in sunlight, and superior chemical and corrosion resistance after curing.
