Title: Method for post-poling mobile ion redistribution in lithium niobate
Inventor: GEOSLING CHRISTINE E
IPC: C30B33/04
Filed: 1998-06-12
Abstract: A method for poling a ferroelectric crystal (10) includes heating the crystal (10) to a temperature above its Curie temperature and applying a first selected voltage to the electrodes to apply an electric field to the crystal (10). The temperature of the crystal (10) is then reduced to a temperature below the Curie temperature of the crystal (10), and a second electric field having polarity opposite to the polarity of the first electric field is applied to the crystal (10). Application of the second electric field reduces nonuniformity in ion concentration across the crystal (10).

Patent CA-2259516-A1 (CA)
Inventor: CARLSON J DAVID
IPC: F16F9/06
Filed: 1997-06-05
Abstract: A controllable vibration apparatus such as a linear fluid damper in which an electrical connection to a controllable valve, preferably located in the piston assembly, is made through a single-strand electrical conductor. In one embodiment, the piston and piston rod (24a) are preferably used as the source of low potential (ground or retun electrical path). An accumulator assembly (44a) preferably including a flexible diaphragm (76a) thereon can be used to provide separation of the fluid-containing chambers from a pressurized accumulator chamber. In magnetorheological (MR) fluid dampers, a special sealing system including a defined relationship between surface finish on the piston rod and magnetically soft particle size is described which enhances life of the seal system. A metal bushing (36a) with a friction-reducing surface treatment is used in combination with an energized lip seal (38a) to prevent escape of the magnetic particles from the damper and support side loads. The magnetically controlled valve can be formed from separate top (80a) and bottom (85a) pole pieces that are spaced from an outer annular ring (82a) to define a fluid passageway. The top pole piece and the annular ring can be secured together by bridging elements such as non-magnetic welds, spot welded plates, or alternatively, formed as a single unit using powdered metal processes such as PIM or MIM. The coil assembly (88a) can be configured with axially-extending pins (94a, 96a) to easily connect with a conductor. An elastomeric element (98a) provides electrical and fluid sealing engagement against the single-strand conductor. Push-on connectors (83a) preferably make the connection between the single-strand conductor and the axially extending pins. In a two single-strand conductor version, one single-strand carries the incoming current and the other the outgoing current.

Title: New metalloproteases of the neprilysin family
Inventor: BOILEAU GUY
IPC: G01N33/566
Filed: 1999-02-11
Abstract: In this paper, we describe RT-PCR strategies that allowed us to identify and clone new members of the NEP-like family. Degenerate oligonucleotide primers corresponding to consensus sequences located on either side of the HEXXH consensus sequence for zincins were designed and used in RT-PCR with mouse and human testis cDNAs. DNA fragments with lengths expected from the sequence of this class of enzymes were obtained. These DNA fragments were cloned and sequenced. Using this PCR strategy and the PCR fragments as probes to screen cDNA  libraries, three new zincin-like peptidases were identified in addition of known members of the family. The cDNA sequences allowed to derive specific probes for Northern and in situ hybridization, and probe human chromosomes to localize the gene and establish potential links to genetic diseases. Furthermore, these cDNA sequences were used to produce recombinant fusion proteins in Escherichia coli in order to raise specific antibodies. Finally, the cDNA sequences were cloned in mammalian expression vectors and transfected in various mammalian cell lines to produce active recombinant enzymes suitable for testing specific inhibitors.
