Patent CA-1299074-C (CA)
Title: Nucleic acid assay
Inventor: HIRSCHFELD TOMAS B
IPC: C12Q1/68
Filed: 1987-03-20
Granted: 1992-04-21
Abstract: ABSTRACT OF THE INVENTION     An assay for polynucleotides employing total inter-nally reflection of excitation radiation at a coating bonded to the surface of an optically conductive glass cell.  The coating initially includes single-stranded polynucleotides coupled to individual attachment sites on the surface of the cell, such pylynucleotides being complementary, at least in part to the single-stranded form of the polynucleotide that is being assayed.  Each molecule of the coupled polynucleotide is connected to the cell curface through a spacer connected to an irre-versibly conjugated polyadenine/polythymidine sequence at one end of the coupled polynucleotide.    When the surface of the coated cell is contacted with a sample that contains single-stranded polynucleotide complementary to the bound polynucleotide, renaturation will occur, forming a double-stranded form of the poly-nucleotide of interest.  A fluorochrome dye specific to that double-stranded form is coupled to the latter, the dye including a chromophore that the excitation radiation will excite into fluorescence.  The induced fluorescence is then gathered and measured.

Title: Device for applying mascara
Inventor: DAHM KARIN
IPC: A45D40/26
Filed: 1987-05-08
Granted: 1993-11-02
Abstract: ABSTRACT            The present invention relates to a rod or pencil-like device for the application of liquid or paste-like substances, this consisting of a tube that contains the substance, one or a plurality of outlet openings for the substance at the head end of the tube, and a twist knob that is arranged at the foot end of the tube, with which a piston can be moved towards the head end of the tube through a spindle, said piston being supported within the tube so as to be unable to twist.  Detent means that are provided between the tube and the twist knob, and which can be over-ridden, ensure that for every rotation or partial rotation there is in each instance a defined quantity of the substances made available.  A particularly simple design configuration of the device can be achieved if a hollow cylindrical neck section is arranged between the twist knob and the spindle that bears the plunger, the diameter of this being smaller than the twist knob but greater than the diameter of the spindle, and a ring is so arranged on the neck section that the neck section can rotate, but is not axially displaceable, within it, the ring being connected to the sleeve such that it cannot rotate independently of it and the detent means being effective between the ring on the one hand and the neck section on the other.  A stopper that can be inserted into the end of the twist knob ensures that the ring is clamped more securely in the tube and the restoring spring effect of the detent nib is limited.

Title: Method of determining the viability of tissue in an organism
Inventor: ANGELLO DEBRA A
IPC: A61K49/00
Filed: 1987-06-10
Granted: 1991-07-09
Abstract: METHOD OF DETERMINING THE VIABILITY OF TISSUE IN AN ORGANISM            Abstract of the Disclosure A method of determining the viability of tissue in a region of an organism comprises the steps of introducing an ATP repleting agent into the region and monitoring the region to determine its effect on T1-201 distribution in the region.  The capability of viable tissue to synthesize ATP and increase its ATP stores provides an indication of the viability of the tissue, in the region.  In a preferred embodiment of the method, ribose, which is a high energy phosphate precursor and an ATP repleting agent, is introduced into heart tissue that is being monitored by T1-201 scintigraphy.  The ribose increases the rate and extent of T1-201 distribution in the heart tissue, thereby allowing the determination of viable "stunned" heart tissue.  That viable tissue is distinguishable from nonviable tissue is attributed to the capability of the former to synthesize ATP and increase its ATP stores in response to the administration of the ATP repleting agent.  Such manipulation of ATP stores in a region of tissue effects a detectable change in T1-201 distribution in that region.  The method permits, therefore, the rapid determination of viable heart tissue.

Title: Technique for loosening, aerating and fertilizing soil around plant roots
Inventor: JOY STANLEY E
IPC: A01C15/02
Filed: 1988-07-26
Granted: 1991-07-16
Abstract: ABSTRACT OF THE DISCLOSURE         A hand-held apparatus is connected by means of an air hose to a high pressure compressor and air tank unit, and is connected by means of a hose to a conventional water faucet.  The device includes a bin for storing granular fertilizer and an air valve connecting the high pressure air supply into a rigid outer tube that is inserted into a pre-drilled hole in the ground. Four holes are provided in the wall of the outer tube near the bottom thereof.  A plug in the bottom of the outer tube has a conical upper surface that deflects compressed air sideways out of the four holes to create small crevices in the ground at the level of the four holes.  An operator stands on a horizontal ground plate attached to the outer tube to seal the hole, and opens the air valve to force high pressure air into the pre-drilled hole.  The compressed air rapidly lifts up the apparatus and the operator standing thereon.  As the compressed air then escapes, the apparatus and person standing on the ground plate falls back to reseal the hole, producing an effective repetitive hammering action that causes the compressed air to more effectively loosen the soil.  The fertilizer in the bin then is released into the outer tube.  The high pressure air valve is re-opened.  The high pressure air forces the granular fertilizer out through the four holes and into the previously created crevices. Pressurized water then is conducted through a water valve to an inner tube concentric with the outer tube, forcing the water into the crevices, dissolving the fertilizer.
