Title: Apparatus for manufacturing optical fiber made of semi-crystalline polymer
Inventor: BODAGHI HASSAN
IPC: D01D5/08
Filed: 2001-09-15
Abstract: An extruder heats polymer resin to produce molten polymer and supplies the molten polymer at a constant pressure. A gear pump is in fluid communication with the extruder, receives the molten polymer and controls the polymer flow rate. A spinneret is in fluid communication with the gear pump and spins the molten polymer into the optical fibers.

Title: Cathodic protection of reinforced concrete with impregnated corrosion inhibitor
Inventor: EFIM YA LYUBLINSKI
IPC: C23F13/04
Filed: 2001-10-17
Abstract: A steel-reinforced structure (1) supplied with an aqueous solution of an inhibitor (8) for the structure, is further protected against deterioration when an impressed cathodic current is applied; preferably the structure (1) is continuously bathed in the inhibitor solution (8); flow of the first impressed current is maintained until flow is relatively constant at a level at least one-half the level at which the first impressed current was initiated.

Patent CA-2429555-A1 (CA)
Inventor: LIU QIANG
IPC: C12N15/12
Filed: 2001-11-20
Abstract: The specificity of binding of a zinc finger to a triplet or quadruplet nucleotide target subsite depends upon the location of the zinc finger in a multifinger protein and, hence, upon the location of its target subsite within a larger target sequence. The present disclosure provides zinc finger amino acid sequences for recognition of triplet target subsites having the nucleotide G in the 5'-most position of the subsite, that have been optimized with respect to the location of the subsite within the target site. Accordingly, the disclosure provides finger position-specific amino acid sequences for the recognition of GNN target subsites. This allows the construction of multi-finger zinc finger proteins with improved affinity and specificity for their target sequences, as well as enhanced biological activity.
