Title: Novel amphipathic graft copolymers, their preparation, compositions thereof, and methods of their use
Inventor: BOTT CRAIG J
IPC: C08F291/00
Filed: 1994-06-29
Abstract: The present invention provides amphipathic graft copolymers comprising a hydrophobic polymer portion combined with at least one hydrophilic polymer portion containing pH independent ionic groups. The amphipathtic graft copolymers can be prepared employing a procedure which comprises adding at least two hydrophobic monomers, wherein at least one of the monomers is a graftable monomer, and hydrophilic monomers, including at least one anionic and/or cationic pH independent ionic monomer, or a post reactive non-ionic monomer that can be converted to a pH independent ionic derivative, to a reaction medium and free-radical polymerizing said monomers and recovering the thus prepared amphipathic graft copolymer. Stable, substantially non-aqueous solution composition of said copolymer containing less that 15 percent by weight water are also provided. The present invention is also useful in preparing a substantially non-aqueous concentrate formulation of a non-ionic surfactant and an amphipathic graft copolymer composition in admixture with a water insoluble organic pesticide which concentrate formulation can be easily diluted with water to form non-settling, freeze-thaw stable formulations. The present invention further provides methods for the use of water-diluted agricultural pesticide concentrate formulations of the above non-ionic surfactant concentrate formulations in the kill and control of agricultural pest.

Patent CA-2224778-A1 (CA)
Title: Optical fibre connector for fibres with cleaved and beveled ends
Inventor: CARPENTER JAMES B
IPC: G02B6/38
Filed: 1996-06-05
Abstract: A device for interconnecting the bare ends of two or more optical fibers uses a common receptacle having a fiber clamping element therein and camming surfaces for actuating the element, and at least one plug having a camming finger for engaging one of the camming surfaces. The camming surfaces are located such that, when only one of the camming surfaces is actuated, the clamping element rocks to a side of the pocket opposite the one camming surface and remains in the open state, but when both of the camming surfaces are actuated, the clamping element is forced to the closed state. The plug includes a fiber protector free to slide within the plug housing, substantially enclosing the bare end of the fiber when the plug housing is removed from the receptacle, but retracting when the plug housing is inserted into the receptacle to direct the bare end of the fiber toward said guide tube. A fiber collet biases the terminal end of the fiber toward the forward end of the plug to place a preload condition on the bare end of the fiber. The connector is particularly suited for cleave-and-bevel installations. The receptacle preferably uses a novel clamping element having two plate members with fiber-contacting surfaces, at least one of said fiber-contacting surfaces having a fiber-receiving groove. Edges of the plates are aligned and held together with a split tube spring. At least one of the plate members is provided with a wire-receiving groove and a wire therein which acts as a fulcrum to allow the plates to pivot along an axis defined by the wire. The split tube spring provides a precisely controlled load along the edges of the plates, allowing the opposite ends to be clamped together (within the guide tube) by a force sufficient to overcome the controlled load of the split tube spring.

Title: Drier with exhaust gas purification
Inventor: KNABE MARTIN
IPC: F26B23/02
Filed: 1997-12-22
Abstract: A drier for wood chips and other bulk materials includes an incinerator for indirectly heating a drying apparatus. The drier operates in a circulatory gas operation with a high water vapor load. All drier exhaust gases are fed to the incinerator and thermally post-combusted there. The drying apparatus includes two drier lines. The first line is heated with the heat of the inflowing vapor, the heat being removed from the exhaust gas flow in a gas-gas heat exchanger and supplied to the vapor feedback. The second drier line includes a heat register, whose heat is extracted from the exhaust gases in a heater, which is arranged directly after the incinerator and reduces the exhaust gas temperature to approximately 500° to 600°. The gas-gas heat exchanger can thus be embodied as a simple sheet metal structure.

Filed: 1997-06-10
Abstract: A roll and blade gap former for a paper machine having first and second wires guided in a respective loop and defining a twin-wire forming zone, a forming gap in which the first and second wires converge before the twin-wire zone, a headbox including a slice channel having a slice opening through which a stock suspension jet is fed into the forming gap to form a web between the wires, and drainage and forming elements arranged in the twin-wire zone for removing water from the web. To provide an improvement in the control of the Z-direction properties of the web, the former includes turbulence generating vanes arranged in the slice channel in the headbox to cause turbulence in the stock suspension jet upon its discharge from the slice opening into the forming gap and a first forming roll arranged in the twin-wire zone and which constitutes the first drainage and forming elements in the twin-wire zone after the forming gap. A run of the twin-wire zone after the forming gap is curved over a wrap angle sector of the first forming roll which is less than about 25~. The forming and draining elements produce a pulsating pressure effect on the web after the curved run of the twin-wire zone over the wrap angle sector of the first forming roll. A method for controlling the anisotropy of web formed in a roll and blade former is also described.

Patent CA-2241934-A1 (CA)
Title: Bypass type flowmeter
Inventor: VAN CLEVE GRAIG BRAINERD
IPC: G01F15/02
Filed: 1997-01-16
Abstract: A bypass flowmeter for measuring the material flow in a conduit. An optimum pressure drop is developed across the flowmeter (104) by coupling the material outlet (107) of the flowmeter to the throat of a venturi (108) positioned within the conduit (101). This increased pressure drop improves the material flow rate through the flowmeter. This enhances flowmeter accuracy and sensitivity and the flowmeter's ability to measure mass flow rates for low density materials such as gas. The ratio of the material flow within the flowmeter to that of the conduit is derived. The material flow information for the conduit is obtained for materials having a varying viscosity by the use of a differential pressure sensor (134) which measures the pressure drop across the flowmeter and transmits this information to instrumentation which uses it to derive material flow information for the conduit with improved precision.  An alternative embodiment not having a venturi operates in the same manner to derive the material flow ratio between the flowmeter and the conduit and, in turn, the total material flow in the conduit.
