Title: Chemical process for amplifying and detecting nucleic acid sequences
Inventor: SEGEV DAVID
IPC: C12Q1/6816
Filed: 1994-06-15
Abstract: The present invention is directed to a method of amplifying and detecting single or double stranded target nucleic acid molecules, Amplification of the target nucleic acid molecule is accomplished by using at least two chemically modified oligonucleotide probes per target nucleic acid molecule to form a joined oligonucleotide product. Each oligonucleotide probe is comprised of a long and short sequence. The long sequence of each probe hybridizes to adjacent regions of the target nucleic acid molecule. The short sequences of each probe hybridize to each other. Chemical functionality groups attached to the short sequences of each oligonucleotide probe covalently combine linking the probes to form a joined oligonucleotide product. The joined oligonucleotide product is formed without the use of enzymes. The reactivity of the chemical functionality groups on each probe is target dependent. Only when the short sequences of adjacent probes are hybridized to each other are the chemical functionality groups on the probes brought into close enough proximity to form a covalent bond and join the probes to form a joined oligonucleotide product.

Title: Electrostatic coating system including improved spray gun for conductive paints
Inventor: HARTLE RONALD J
IPC: B05B5/025
Filed: 1996-01-31
Abstract: An electrostatic coating system includes an improved spray gun which is connected in fluid communication with a source of electrostatically charged electrically conductive liquid coating material.  An electrically nonconductive coating material tube is disposed in an electrically conductive handle portion of the spray gun and extends into an electrically nonconductive barrel or extension portion of the spray gun.  The coating material tube is preformed to and maintains a configuration corresponding to a configuration of a passage in the handle and extension portions of the spray gun.  A packing cartridge is connected between the trigger and the spray gun valve and has a tapered end portion which is encircled by an O-ring seal which engages a tapered bore in the extension portion of the spray gun.  The handle portion of the spray gun is grounded through a conductive inner layer of an air conduit connected to the spray gun.  An atomizing air passage extends from the handle portion of the spray gun through the extension portion to the nozzle.  A pattern air passage also extends from the handle portion through the extension portion to the nozzle.   Thumb wheel operated air flow control valve assemblies are located in the atomizing air and pattern air passages.  A pattern air shut-off valve is installed in series with the pattern air flow control valve to quickly shut off the flow of pattern air.  The gun is very light weight but effectively protects the operator from electric shock.  Charged conductive coating material is supplied up the handle of the gun through a nonconductive fitting installed into the bottom of the handle.  A floating field electrode, comprised of the metal valve shaft of the spray gun valve, has a tapered point located in the spray gun nozzle to strengthen the electrostatic field, and thereby improve the efficiency of the electrostatic coating system.
Patent CA-2169971-A1 (CA)
Title: Method and apparatus for prestressing strawbale and like building constructions
Inventor: CHAPMAN LINDA
IPC: B30B9/30
Filed: 1996-02-21
Abstract: A method and apparatus is disclosed for prestressing stacked strawbale and like building constructions, in which the prestressing is effected by means of the wire or plastic mesh which covers the exterior and interior surface of the strawbales, and which is normally required in any case to reinforce final stucco/gypsum renderings or the like against shrinkage cracking. The tensioning of the mesh simultaneously and equally compresses the strawbales internally and together. That compression increases the shear resistance as well as compression properties of the bales, while the tensioning of the mesh acts with those properties to produce an adequate composite building structure, obviating most or all dependency on the tensile qualities of any final renderings or coverings. The prestressing is effected pneumatically, hydraulically, or mechanically. The operation also accomplishes the final levelling of the walls, and can be used as well to produce gable roof structure or arched or vaulted roof structures.

Title: Magnet motor stator
Inventor: SUHARA TOSHIHIRO
IPC: H02K9/06
Filed: 1997-03-27
Abstract: In the magnet motor stator, magnet insertion holes are provided, a pole is formed with a plurality of insertion holes, and flat magnets are inserted into the respective insertion holes.      From among stator core plates made by stamping a steel sheet such as a silicon steel sheet, a plurality of stator core plates without magnet insertion holes and a plurality of stator core plates with magnet insertion holes are alternately laminated.      The magnet is held only at the portion formed by laminating a plurality of stator core plates having magnet insertion holes. At this point, the portions formed by laminating stator core plates without magnet insertion holes are arranged at the upper and lower ends of the stator. The simple flat shape of the magnet ensures easy preparation. The need for the positioning operation upon attaching the magnets to the stator or the bonding operation using an adhesive is eliminated. It is thus possible to manufacture a stator at a lower cost, and to reduce the sire and weight of the magnet motor used for an electric bicycle.
Patent CA-2202317-A1 (CA)
Inventor: HERSHBERGER DAVID
IPC: H03C3/40
Filed: 1997-04-10
Abstract: An FM transmitter includes I and Q channels, each deriving a baseband sinusoidal wave having a frequency determined by speech and/or music broadcast information amplitude  and  nominally  having  the  same  maximum amplitude.  Each wave drives a different balanced mixer, each responsive to orthogonally phased carrier waves. Outputs of the mixers are added to derive a frequency modulated  output  wave.    The  channels,  mixers,  and circuitry associated with them tend to introduce unwanted components in the output wave.  Offset, peak amplitude, phase and relative delay of the added mixed outputs are such  that  the  unwanted components  are  substantially eliminated from the output wave.  The sinusoidal waves are derived by DACs responsive to signals derived by a digital processor having a memory storing amplitude vs. phase position values and slope vs. phase position values that are combined in response to samples of the broadcast information.  The stored amplitudes and slopes control sinusoidal wave offset, peak amplitude and phase.  The waves and delay times of the channels driving a power amplifier of  the transmitter are calibrated on line according to certain embodiments.
