Patent CA-2048906-A1 (CA)
Title: Microemulsion diesel fuel compositions and method of use
Inventor: BOCK JAN
IPC: C10L1/222
Filed: 1991-08-09
Abstract: The present invention relates to translucent and thermodynamically stable diesel fuel compositions having improved combustion efficiency and reduced smoke, particulate, CO, and NO x emissions. The diesel fuel compositions comprise a diesel fuel, water, or an aqueous solution of a low molecular weight alcohol and/or a water-soluble reagent, and a surfactant system which comprises a balanced blend of one or more hydrophilic surfactants and one or more lipophilic surfactants, wherein the diesel fuel composition can contain as high as 30 weight percent of aqueous phase with an aqueous phase/surfactant ratio at least 2/1.      The surfactant system may contain, in addition to the hydrophilic and lipophilic surfactants, cosurfactants and polar organic solvents. The reagent solution comprises aqueous solutions of an additive selected from the group consisting of inorganic oxidizing agents, low molecular weight polar organic oxidizing agents, and nitrogen oxide-containing compounds which act as cetane improvers and/or combustion modifiers.      These additives offset the well-known loss in cetane number and/or the ignition delay caused by dispersed or microemulsified water and eliminate the need to change engine operating parameters.

Title: Method and apparatus for drying, curing and supporting a coated strand
Inventor: JENSEN THOMAS H
IPC: C03C25/10
Filed: 1991-09-03
Abstract: A plurality of coated strands are conveyed through a drying oven.  A plurality of nozzles impinge the upper surface of the coated strand as it passes therethrough.  Baffle plates positioned below the strands redirect the gas stream such that, after the gas stream has passed through the strands, it is redirected so as to impinge on an opposite surface of the coated strand.  The strand is supported by positioning it between an additional pair of nozzles that are tilted towards each other such that an upwardly directed gas stream issuing from the first nozzle intersects an upwardly directed gas stream issuing from the second nozzle along a line which along with the strand, forms a generally vertical plane.  The combined upwardly directed force from the gas streams lifts and supports the strand while the opposing lateral force from each gas stream on the strand tend to reduce and lateral movement and stabilize its relative position.

Abstract: Abstract of the Disclosure An acceleration sensor that comprises a body of non-magnetic construction having a linear internal cavity of uniform cross section, and a pair of permanent magnetics movably mounted within such cavity with like magnetic poles opposed to each other, such that the magnetics are urged to opposite ends of the cavity by force of magnetic repulsion therebetween.  At least one weigand wire is positioned externally of the cavity between the cavity ends, and has a longitudinal dimension parallel to the lineal dimension of the cavity.  The weigand wire is characterized by two stable magnetic flux-generating states dependent  upon  application  of  an  external  magnetic  field  of appropriate polarity for switching between such states. An electrical coil is positioned adjacent to the weigand wire, and is responsive to switching between the two flux-generating states for generating a sensor output signal as a result of acceleration forces on either of the magnets sufficient to overcome the force of magnetic repulsion therebetween, and thus to bring one of the magnets into proximity with the wire.

Abstract: In a DPCM predictive encoder for performing DPCM prediction by digitizing a NTSC color television signal with a rate three times of a color sub-carrier frequency, a two-frame predictor which outputs a differential signal over two frames is employed as one of predictors.   A predictor switcher adaptively selects one of prediction information as an optimal prediction signal and selects corresponding  differential  information  as  an  optimal differential signal. This differential signal is quantized by a quantizer.   The quantized output and the optimal prediction signal are summed by an adder and supplied to the predictors as a local decoding signal.
