Title: Light scatter-based immunoassay without particle self aggregation
Inventor: HANSEN W PETER
IPC: G01N33/553
Filed: 1993-12-22
Abstract: A homogeneous immunoassay method for the simultaneous determination of one or more antibody, antigen or hapten analytes in a fluid sample, that comprises the quantification of the effect of said analytes on the statistical changes in a dimension of a light scatter pulse height distribution histogram of relatively large diameter monodisperse binding molecule-coated polymeric microspheres induced by the binding to said microspheres of polydisperse binding molecule-coated colloid metal particles of relatively small diameter. For simultaneous assays of multiple analytes, different diameter or refractive index microspheres are assigned to each analyte. The assay may be used in forward binding, displacement, inhibition, and competition type systems, with the direction of the change in histogram dimension depending on the system. A convenient dimension to measure is the normalized peak width of a graphical representation of the histogram.  For simultaneous assays for multiple analytes, a monodisperse polymeric microsphere of unique diameter or refractive index is dedicated to each analyte, so as to generate multiple histograms, one for each analyte.  Polydisperse binding molecule-coated colloid metal particles, when used in effective concentrations, will also serve as a scavenger means to reduce the interfering effects of non-specific substances in the analyte-containing fluid samples, particularly when said samples are of biological origin. An improved sheath flow cell for a FPA is also described.

Patent CA-2166537-A1 (CA)
Title: Treatment of presbyopia and other eye disorders
Inventor: SCHACHAR RONALD A
IPC: A61F9/007
Filed: 1993-07-13
Abstract: Presbyopia and hyperopia are treated by increasing the ampli-tude of accommodation by increasing the effective working distance of the ciliary muscle. To this end, the sclera over the ciliary body is ex-panded by suturing thereto a relatively rigid band slightly larger than the sclera, surgical alloplasty, or by weakening the sclera by surgery or treatment with enzymes, heat or radiation, which then expands due to intraocular pressure. The scleral expansion band (102) comprises an anterior (108) and posterior (106) rim, and a web (104) extending between the rims. The band may be provided with one or more holes to assist in suturing. The same goal is achieved by shortening the zo-nules by application of heat or radiation or by surgery. Presbyopia is arrested by inhibiting the continued growth of the crystalline lens by application of heat, radiation or antimitotic drugs to the epithelium of the lens. Primary open angle glaucoma and/or ocular hypertension can be prevented and/or treated by increasing the effective working distance of the ciliary muscle.

Patent CA-2181893-A1 (CA)
Title: Production of polysuccinimide
Inventor: BATZEL DANIEL A
IPC: C08F8/12
Filed: 1995-01-27
Abstract: Polysuccinimide is prepared by reacting an unsaturated C2 dicarboxylic acid or anhydride thereof, e.g., maleic acid, fumaric acid, and maleic anhydride, with a particulate ammonium salt that is thermally decomposable to liberate ammonia. The reaction is carried out at a temperature which is above the thermal decomposition temperature of the ammonium salt and for a time period which is sufficient for the acid or anhydride to react with the ammonia liberated from the ammonium salt and for polymerization to occur. The present method avoids the prior art problems of controlling ammonia losses and water removal. The product polysuccinimide can be readily hydrolyzed to polyaspartic acid or a salt thereof, if desired.

Title: Radio frequency and electrostatic discharge insensitive electro-explosive devices having non-linear resistances
Inventor: BAGINSKI THOMAS A
IPC: F42B3/13
Filed: 1996-08-16
Abstract: An electro-explosive device has two serpentine resistors fabricated on a thermally conductive substrate with the resistors being interconnected by a central bridge element.  The resistance of the bridge element is much lower than that of the serpentine resistors and the serpentine resistors have a much larger surface area to volume ratio.  A layer of zirconium is placed on the bridge element and explodes into a plasma along with the bridge element in order to ignite a pyrotechnic compound.          The resistance of the bridge element increases with temperature whereby the bridge element receives more of the energy from the applied signal as the temperature increases.  The EED is insensitive to coupled RF energy and to an electrostatic discharge since most of the energy from these stray signals is directed to the serpentine resistors and not to the bridge element.  In another embodiment, two of the resistors are metal-oxide phase variable resistances and a third resistor is formed from a bowtie-shaped layer of zirconium.  The resistances through the metal-oxide phase layers decrease with signal intensity whereby the zirconium can receive most of the energy from a high intensity firing signal.  A shunting element, which may be placed across an EED, has a bowtie-shaped conductive layer formed on a substrate.  The conductive layer explodes in a plasma above a certain signal intensity.  The shunting element may comprise another type of device, such as a diode, capacitor, etc.

IPC: B01F13/00
Filed: 1997-01-03
Abstract: L'eau étant le moyen le plus pratique et encore aujourd'hui le moyen le plus utilisé pour combattre le feu, il est possible d'augmenter son efficacité comme agent extincteur par l'ajout de particules minérales incombustibles. On sait que la glaise est un matériau naturel constitué de sédiments minéraux très fins, que l'on désigne argile. A l'état naturel existent des dépôts d'argiles dites sensibles, dont notamment les argiles marines qui ont comme caractéristique, une forte teneur en eau, la consistance d'une pâte plastique relativement molle, dont la sensibilité au remaniement peut être très grande et même infinie, d'où sa propension à la liquéfaction en vase (boue liquide), lorsque remaniées. Dans la présente invention, un appareil mécanique désagrège la glaise de sa phase solide, c'est-à-dire en vrac à l'état de pâte plastique, à une phase liquide, soit une boue vaseuse. Cette transformation est obtenue par le frottement rapide d'une courroie dont la surface externe comporte des empreintes profondes en plus d'exercer une pression continue contre une masse de glaise, ce qui brise sa consistance et la liquéfie. L'appareil est conçu pour fonctionner dans une benne mobile qui permet l'entreposage d'une réserve de glaise en vrac.
