Patent CA-2036267-A1 (CA)
Inventor: HERSCOVICI SAUL
IPC: F16H9/00
Filed: 1991-02-13
Abstract: A mechanically variable transmission is provided by a novel arrangement of sheaves in combination with a power ring which can be utilized with a planetary device to smoothly varying output speed from maximum rotational speed in one direction to maximum speed in the opposite direction while passing through or maintaining zero output speed or any other speed in a forward or reverse direction while the input speed is varied or remains constant.  The novel arrangement provides changes in the output speed over the entire range of engine power and under all load conditions since declutching is not necessary to shift gears allowing the engine to operate at a constant horsepower over the entire range of throttle settings and can enhance engine efficiency by allowing the engine to operate at the lowest possible speed and highest torque.  The infinitely variable speed transmission and engine can be controlled with a computer control to maintain the engine at full torque but the lowest possible speed while varying the infinitely variable transmission ratio to maintain a constant or desired ground speed.

Inventor: LEES ROBERT S
IPC: A61P3/06
Filed: 1991-08-13
Abstract: A therapeutically effective amount of soluble phospholipase A2 is administered into a subject for lowering the low density lipoproteins ("LDL") in the blood.  Phospho-lipase A2 modifies the plasma LDL by hydrolyzing the phospholipids present in LDL.  As a result, the modified LDL is rapidly removed from the bloodstream by the catabolic processes.

Abstract: A B S T R A C T   O F   T H E   D I S C L O S U R E       The drive system is for use on a web printing machine of the kind having at least first and second printing units drivable from a prime mover.  Drive is transmitted through a drive shaft which is common to the printing units.  The first printing unit is disposed between the prime mover and the second printing unit.  The drive system comprises a drive unit having a motor for transmitting drive to a movable member of the first printing unit.  While drive from the prime mover to the first printing unit is interrupted.  The drive motor enables an operation requiring drive of the movable member to be performed on the first printing unit while the second printing unit remains drivably connected to the prime mover through the driveshaft.  The isolating system comprises a switch for disabling on the first printing unit a sensing circuit which normally operates to inhibit drive to the first and second units from the prime mover as a result of movement of guards on the first unit into an inoperative position.  Operation of the switch is possible only after drive to the first print unit has been interrupted.

IPC: A61B5/274
Filed: 1992-03-26
Abstract: ELONGATED STRIP ELECTRODE ARRANGEMENT AND METHOD                  Abstract of the Disclosure An elongated strip electrode arrangement and method are disclosed.  The electrode includes an electrically conductive layer having a layer of conductive adhesive at one side and an electrically non-conductive layer at the other side with the non-conductive layer having a series of longitudinally spaced pairs of apertures therein through which a connector pin is insertable to establish and maintain electrical contact between the pin and the conductive layer.  The apertures of each aperture pair are closely spaced from one another so that a connector pin when inserted through one of the apertures a sufficient distance can extend from the electrode through the other aperture.  The longitudinally extending series of aperture pairs enables selection of electrode strips of different lengths from a roll of the strip electrode.          The strip electrode includes an elongated non-conductive strip of small width aligned with the series of aperture pins and positioned between the conductive layer and the adhesive layer to provide user protection, and a piece of adhesive can also be utilized to further prevent retraction of a pin when positioned in an aperture pair.

IPC: C03C17/04
Filed: 1992-05-05
Abstract: ABSTRACT         A process for producing decorated glass-ceramic articles is described, an article of crystallisable glass being first decorated with a ceramic colour and then being converted into a glass-ceramic article by heat treatment with simultaneous burning-in of the ceramic colour, is improved by treating the glass article, before decorating, for 10 minutes to 50 hours with a Br?nsted acid at temperatures between 50 and 800°C. As a result of this treatment, the surface layer of the glass article is modified in such a way that the layer of ceramic-colour sinks into the surface of the article during burning-in/ceramicising. The use properties of the glass-ceramic are themselves not changed as a result.

Filed: 1991-11-29
Abstract: L'invention se rapporte à un joint obtenu par soudage électrique, qui comporte un corps principal et, dans le prolongement de sa direction axiale, un matériau en alliage magnétique incorporé dans le corps principal à proximité de sa surface de jointure. Dans la partie destinée à former une zone froide sur la surface extérieure du corps principal, on prévoit un élément barrière. La surface de jointure du corps principal est alors mise en contact avec l'élément à joindre. Dans ces conditions, lorsqu'on applique un courant haute fréquence au matériau en alliage magnétique par induction électromagnétique, le matériau en alliage magnétique génère de la chaleur et le corps principal s'assemble par fusion avec l'élément à joindre. Etant donné que l'élément barrière protège le matériau en alliage magnétique contre les ondes électromagnétiques, ce matériau ne génère pas de chaleur et la zone froide est alors formée dans cette partie.

Title: Stimulated raman laser or amplifier using axicon pumping
Inventor: FOURNIER GEORGES R
IPC: H01S3/30
Filed: 1992-08-24
Abstract: ABSTRACT     A raman cell oscillator/amplifier arrangement comprising a cell containing a raman high pressure gas or liquid medium with an axicon being located at each end of the cell, one axicon having an input window for a laser pump beam and the axicon at the cell's other end having an output coupler for the raman process converted beam.  The axicons directs the laser pump beam towards an extended line focus along the axis of the cell at a shallow angle, the extended line focus for each axicon being collinear with each other to produce an extended raman gain region.  By suitable design, it can be ensured that the pump beam energy density at focus is lower than either an optical breakdown or Brillouin backscatter threshold.  This provides a means of efficiently producing a raman laser or amplifier having an extended raman gain region without developing problems of optical breakdown, Brillouin backscattering or self-focusing in the case of a liquid raman media.

Title: Improved immunohistochemical staining method and reagents therefor
Inventor: MILLER PHILLIP C
IPC: G01N35/00
Filed: 1991-02-27
Abstract: The present invention provides an improved method for staining slides using immunochemical reagents. The method comprises the following steps. The assay region of a slide (the region containing the tissue section) is washed with an improved rinsing solution comprising water and a detergent. An evaporation inhibitor liquid is applied to the slide to cover the assay region. For antigens requiring unmasking, the tissue section is combined with an improved, stabilized proteolytic enzyme solution. The slide is rinsed, and the evaporation inhibitor liquid is reapplied to the slide. A primary antibody in an improved diluent containing globulins from the same species as a second antibody is combined with the tissue section for a time sufficient to substantially complete antibody binding. The slide is rinsed, and the evaporation inhibitor liquid is reapplied. A labeled second antibody in the improved diluent is combined with the tissue section for a time sufficient for substantially complete antibody binding. The slide is rinsed, and the evaporation inhibitor liquid is reapplied to the slide. Color development reagents, including, in a preferred embodiment, a stabilized diaminobenzidine (DAB) solution, are combined with the tissue section for a time sufficient for color development. Following rinsing, the tissue section is ready for analysis.
