Patent CA-2351421-A1 (CA)
Inventor: POMMER RICHARD J
IPC: H05K3/36
Filed: 1999-11-19
Abstract: A printed circuit assembly (100) and method of making the same facilitates the attachment of high density modules (120) onto a printed circuit board (110).  In one embodiment, the high density modules are attached to the printed circuit board using an adhesive having a conductive material disposed within at least one via. A printed circuit assembly and method of making the same utilize in another embodiment an interlayer interconnecting technology incoporating conductive posts that are deposited on one of a pair of contact pads formed on a module that opposes a printed circuit board and is thereafter bonded to the other in the pair of contact pads during lamination. Fusible material may be utilized in the conductive posts to facilitate mechanical bonding to a contact pad, and the posts project through a dielectric layer disposed between the printed circuit boards, thereby forming the electrical connections between the boards at discrete locations. The conductive posts may also comprise a conductive ink.

Title: Low oxygen culturing of central nervous system progenitor cells
Inventor: STUDER LORENZ
IPC: A61K35/12
Filed: 1999-11-18
Abstract: The present invention relates to the growth of cells in culture under conditions that promote cell survival, proliferation, and/or cellular differentiation. The present inventors have found that proliferation was promoted and apoptosis reduced when cells were grown in lowered oxygen as compared to environmental oxygen conditions traditionally employed in cell culture techniques. Further, the inventors found that differentiation of precursor cells to specific fates also was enhanced in lowered oxygen where a much greater number and fraction of dopaminergic neurons were obtained when mesencephalic precursors were expanded and differentiated in lowered oxygen conditions. Thus at more physiological oxygen levels the proliferation and differentiation of CNS precursors is enhanced, and lowered oxygen is a usefu l adjunct for ex vivo generation of specific neuron types. Methods and compositions exploiting these findings are described.

Patent CA-2354754-A1 (CA)
Inventor: OMARU ATSUO
IPC: H01M10/0525
Filed: 2001-08-07
Abstract: The present invention provides a non-aqueous electrolyte secondary cell including: a lithium-nickel composite oxide as a cathode active material and a material having a specific surface in the range from 0.05 m2/g to 2 m2/g as an anode active material. When A is assumed to be the weight of the lithium-nickel composite oxide and B is assumed to be the weight of the cathode active material other than the lithium-nickel composite oxide, the mixture ratio R expressed A/(A + B) is in the range from 0.2 to 1. This combination of the cathode active material and the anode active material enables to obtain an improved anti-over discharge characteristic even when an anode current collector contains Cu.

Title: Folding multipurpose tool with floating springs
Inventor: RIVERA BENJAMIN C
IPC: B25F1/00
Filed: 2001-09-19
Abstract: A folding multipurpose hand tool including folding pliers and other tool blades and bits. A pair of handles each have a pivot axle at each end. A base of each jaw of the pliers is mounted on the pivot axle at one end of a handle, allowing the handles to fold around the jaws to a compact folded configuration of the tool.      Each handle has frame side members with attached flanges.      Elongate springs lie alongside the handle frame side members and fit around the flanges, rather than being riveted to the handle frame side member. The springs press against the base of a pliers jaw or other tool bit or blade, or a spacer, to keep each tool blade, jaw, or bit in a folded position or support it in a deployed position. Additional frame side members each include a flange and support a spring and one or two additional tool blades or bits. The pivot axles interconnect the handle frame side members and the tool bits. A special spring extends between the pivot axles and controls a tool bit mounted between the ends of a handle on a pivot on a frame side member.

Title: Pipe running tool
Inventor: BOYADJIEFF GEORGE
IPC: E21B19/00
Filed: 2000-03-03
Abstract: A pipe running tool for use in an oil drilling system and the like comprises a lower drive shaft adapted to engage a drive shaft (28) of a top drive assembly for rotation therewith.

Abstract: A flowing junction reference electrode exhibiting heretofore unattainable potentiometric characteristics is described, comprising a microfluidic liquid junction member that is situated between a reference electrolyte solution and a sample solution. This microfluidic liquid junction member has an array of nanochannels spanning the member and physically connecting the reference electrolyte solution and a sample solution, but while the electrolyte solution flows through the array of nanochannels and into the sample solution at a linear velocity, the sample solution does not substantially enter the array of nanochannels via the mechanisms of diffusion, migration, convection or other known mechanisms.  The number of nanochannels in the array is preferably between approximately 8 and approximately (100). Also preferably, the nanochannels are substantially straight and are substantially parallel to one another; such an array of nanochannels is herein described as anisotropic. The nanochannels are also preferably coated. The widths of any nanochannels in the array of nanochannels are preferably uniform, in that the width of any nanochannel is substantially equal to the width of any other nanochannels in the array.  The nanochannels preferably have widths of greater than approximately 1 nanometer and less than approximately 500 nanometers, and most preferably of 70 nanometers. The electrode may be constructed out of any suitable material, and is preferably constructed of a polymer, most preferably a polymer selected from the group consisting of polycarbonate and polyimide, and may also preferably be constructed of silicon, glass, or ceramic.
