Patent CA-2327016-A1 (CA)
Inventor: HAYNER ROGER E
IPC: C09D195/00
Filed: 2000-11-28
Abstract: A sulfur in oil in asphalt and polymer blend is disclosed. An asphalt and polymer blend is first prepared and then a slurry of solid sulfur in liquid oil added. Addition of a slurry of solid sulfur in oil permits rapid and effective dispersion of the sulfur component in the asphalt/polymer blend. Uneven mixing, which can occur when sulfur is separately added as a solid to the asphalt blend, is avoided. Polymer use is optimized because polymer swelling can be completed before cross-linking occurs. The method is safer because formation of explosive clouds of sulfur dust is avoided.

Abstract: In an optical reflection grating with a multitude of parallel grooves (5), for a ratio of grating period (g) to wavelength (.lambda.) of smaller than 0.9, preferably of smaller than 0.7, the groove depth is chosen so deep that the diffraction efficiencies (DE) for TE  and TM waves of a certain wavelength (.lambda.) differ by less than 10%, preferably by less than 5% from one another and are at least 60% respectively. That means, the diffraction efficiency (DE) is practically independent fro   m the polarization direction of the incident light and is very high.

Abstract: An Si-base thermoelectric conversion material and a thermoelectric conversion element, wherein without lowering the Seebeck coefficient and electric conductivity of the Si-base thermoelectric conversion material, the heat conductivity of the material can be greatly lowered to realize a great improvement in performance index. A crystalline structure, which is a polycrystalline structure, having crystal grains of Si-rich phase and also having an added element-rich phase containing one or more added elements precipitated in the grain boundaries is formed, whereby the Seebeck coefficient becomes very high and the heat conductivity becomes low, making it possible to greatly increase the thermoelectric conversion efficiency; thus, there is provided an Si-base thermoelectric conversion material consisting mainly of Si, which is a naturally abundant element, and causing least environmental pollution. For example, the addition of C, Ge or Sn to the Sibase thermoelectric conversion material makes it possible to greatly reduce the heat conductivity without changing the carrier concentration in the Sibase material. To lower the heat conductivity, the optimum amount of addition is 5-10 atom percent. The material has a structure in which the group IV elements and addition elements added to prepare p-type or n-type semiconductors precipitate in the grain boundaries of the polycrystalline Si, whereby there is obtained a p-type or n-type semiconductor having a carrier concentration of 1017 - 1021 (M/m3) and a heat conductivity of 50 W/m\Abull;K or less.

Inventor: DANABOYINA RAMAIAH
IPC: C07D401/14
Filed: 2001-02-27
Abstract: The present invention provides a series of novel bifunctional molecules based on viologen linked acridine, bisacridine and bisacridinium salts of the general formula 1(1a, 1b, 1c and 1d) and or pharmaceutically acceptable derivatives thereof, which can be used as phototherapeutic and catalytic photoactivated DNA cleaving agents.  These molecules are very stable and exhibit high solubility in buffer at physiological conditions. They undergo strong binding with DNA through intercalation and groove binding interactions and show remarkably high affinity for poly(dA).poly(dT) sequences. Upon photoactivation, they cleave DNA catalytically and selectively at guanine (G) sites in duplex DNA exclusively through cosensitization mechanism with a preference for 5'-G over 3'-G. They induce unusally high specificity of cleavage at G site of the AG two base bulge sequences. Accordingly, the viologen linked acridine based molecules described herein are extremely useful as probes for DNA  structures and catalytic photoactivated DNA cleaving agents in biological applications.

Filed: 1999-12-03
Abstract: A proportional actuator (10) for proportional control including a saturation tip (24) formed on the movable armature (16) for movement within a step-wound coil (18). The coil providing clearance for the saturation tip, allowing the coaxial diameters of a magnetic pole piece (14) and the armature. The configuration of the armature provides significantly higher magnetic force attraction between the magnetic pole piece and the armature because of the increased coaxial diameters of the armature and the pole piece. In addition, because of the increased diameter of the armature, the surface area of the armature that is exposed to the saturation tip is increased, thereby increasing the amount of flux that is coupled to the magnetic pole piece by the saturation tip. The proportional actuator is described with reference to applications in proportional control valves. Highly preferred embodiments of the proportional control valve include a damping mechanism for minimizing overshoot by providing restricted fluid flow path between the magnetic pole piece and the armature and tank pressure for fluid being supplied to or removed from the apparatus being controlled by the proportional control valve.

Abstract: Stacks (1) of printed products which products are characterized in that they  each have an edge of increased thickness are wrapped in such a manner that those stack sides in which the above-mentioned edges are arranged are completely covered by the coating (4) and are thus well protected. Since sai d stacks (1) are less stable in a direction transversal to the mentioned edges , the stacks (1) are discharged from a stacking shaft (20) in which the stacks  are produced in a direction parallel to the mentioned edges and directly between the forks (12 and 13) of a pair of forks (12/13). The stack (1) is compressed between the forks (12 and 13) and the pair of forks (12/13) containing the compressed stack (1) is guided through a curtain (14) of a coating material. Said coating material is closed around the pair of forks (12/13) and the stack (1). Once the coating is applied, the coated stack (1/ 4) is separated from the pair of forks (12/13) by performing a movement of the pair of forks (12/13) relative to the stack (1/4) and is conveyed on.</SDOAB >
