Patent CA-2319281-A1 (CA)
Inventor: SNOPEK DAVID A
IPC: H02K3/40
Filed: 2000-09-14
Abstract: There is disclosed a groundwall insulation system for use in dynamoelectric machines carrying voltages above 4 KV and preferably in the order of 13.8 kV, or higher. The groundwall insulation comprises two layers of insulation wound onto the conductors of the high voltage winding. The first layer of insulation has a first permittivity that is greater then the permittivity of the second layer of insulation wound onto the first layer of insulation. As a consequence, at the juncture between the first and second layers there is a sharp increase in the electric field profile as seen through the groundwall insulation. This step increase in the electric field profile results in the electric field adjacent the conductor having a maximum magnitude that is less than that normally experienced by insulation systems in the past. By reducing the maximum magnitude of the local electric field profile within the groundwall insulation the life of the insulation and hence the electrical conductor is improved while at the same time permitting a reduction in the thickness of the groundwall insulation.

Title: Rotary valve actuator and linkage
Inventor: BAUMANN HANS D
IPC: F15B15/08
Filed: 1999-02-19
Abstract: A rotary valve actuator and linkage include an actuator having a tubular housing (30) with end caps and a piston (82) that is moved by fluid pressure against a compression spring (98). A rolling diaphragm (142) is used to bias the piston. A pair of slots (60) are provided on opposite sides of the housing, and a linkage having two arms (64, 66) is interconnected with the piston through the slots. The linkage is coupled to a rotary valve shaft (68) and linear movement of the piston causes rotational movement of the shaft. The linkage includes two separate arms and a centerpiece (150). In one embodiment, the arms and the centerpiece interengage each other at angled surfaces that force the centerpiece and the arms into radial engagement with the shaft when axial compression is provided to the arms and centerpiece to force them toward each other. In another embodiment, each of the linkage arms is provided with a collet having radially movable portions. The collet is forced into a recess in the centerpiece, causing the radially movable portions to be locked in engagement with the shaft.
Patent CA-2322554-A1 (CA)
Inventor: FELKER JOSH
IPC: C12N5/08
Filed: 2000-10-20
Abstract: The invention relates to formation of replicative cells from multipotential stem cells. As the most numerous cell type in the brain, astrocytes are coupled via gap junction channels. It is believed that communication among astrocytes is normally regulated by extracellular ions, neurotransmitters and neuromodulators. However, the level of astrocytic coupling is altered in abnormal conditions such as stroke, brain trauma and Alzheimer's disease. A well established human progenitor cell line, NT2/D1, has been previously differentiated into pure neuronal cultures. For the first time, we report the differentiation of NT2/D1 cells into astrocytes, which express connexin43 and are coupled via gap junctions. Thus, human NT2/D1 cells are not merely committed neuronal progenitors but, similar to the embryonal stem cells, they can give rise to both lineages. This has potential in treatment of various forms of neurological deficiency. Other replicative cells may be formed from multipotential stem cells according to the invention.

Title: Nucleic acid detection
Inventor: NELSON LISA S
IPC: C12Q1/68
Filed: 1999-03-11
Abstract: This invention discloses methods for detecting specific nucleic acid sequences, interrogating the identity of a specific base within a sequence, and assaying endonuclease and exonuclease activity. DNA or RNA probes are hybridized to target nucleic acid sequences. Probes that are complementary to the target sequence at each base are depolymerized, while probes which differ from the target at the interrogation position are not depolymerized. The nucleic acid detection systems utilize the pyrophosphorolysis reaction catalyzed by various polymerases to produce deoxyribonucleoside triphosphates or ribonucleside triphosphates. dNTPs are transformed to ATP by the action of NDPK. The ATP produced by these reactions is detected by luciferase or NADH based detection systems.

Title: High performance optical link
Inventor: GERTEL EITAN
IPC: H04B10/18
Filed: 2000-11-28
Abstract: An optical link is described for transmission of an RF signal using an optical fiber having opposing ends and configured such that unwanted distortion signals are produced when optical signals pass through the optical fiber. At least first and second optical signals are transmitted through the optical fiber, where the optical signals have been modulated with an RF signal in such a way that a predetermined relationship is produced between the RF signals modulated on the first and second optical signals. At the opposing end of the optical fiber, a receiving arrangement receives the modulated first and second optical signals including the unwanted distortion signals produced during the transmission through the optical fiber. The receiving arrangement then regenerates the RF signal from the modulated first and second optical signals while causing the unwanted distortion signals to be canceled based on the predetermined relationship between the RF signals modulated on the first and second optical signals.
