Abstract: MECHANICAL PULPING                         ABSTRACT         Thermomechanical, chemimechanical, and chemithermomechanical pulps are produced in a manner such that they have enhanced drainage and strength, and/or can be bleached to enhanced brightness levels and in a simple manner.  Chips are impregnated with chemical or thermal treating fluid, such as by passing heated sulfite liquor countercurrent to the flow of the chips.  After impregnation, and where applicable cooking, the chips are washed by a countercurrent flow of wash liquid including chelating and surface active agents.  Immediately after washing the chips are mechanically refined to produce a mechanical pulp by passing the chips through a first pressurized refiner, screening the pulp discharge from the first refiner to provide first and second streams, passing the first stream to a second pressurized refiner having a discharge, and passing the second stream directly to the discharge of the second refiner.  Further treatment of the pulp, including bleaching utilizing hydrosulfite and/or peroxide, is effected in order to achieve a mechanical pulp having the desired properties.

Abstract: Abstract A revetment panel for installation along embankments and other earthen structures, including structures partially or fully covered by water, which utilizes a fabric web having a plurality of compartments.         The compartments are staggered in relation to each other and separated by selvage.  The web is formed of two fabric layers, which are woven separately to form the compartments and fastened together to form selvage separating them.  Slots are formed in the selvage which allow cables to pass longitudinally through the web and interlock the compartments during filling.  The web is transported to its installation site and placed.  The compartments in the web are then inflated with the filler material, which may be cementitous slurry or mortar consisting in part of sand and gravel found near the installation site, or simply a mixture of sand, gravel, and water or other ingredients.  The resulting matrix of forms interconnected by fabric and cable provides a durable, economical and flexible erosion control layer.  Later, the fabric may wear away leaving a highly articulable mat of hardened forms interconnected and interlocked by longitudinal cables or other connecting means.

Abstract: ABSTRACT OF THE DISCLOSURE     A method for making a diffraction grating utiliz-ing a laser source, a beam splitter to split the light from the laser source into two light fluxes, a collimator to convert each light flux into a light flux which is parallel and enlarged in diameter, a mirror to irradiate each light flux on a substrate coated with a photoresist, and a photomask on the photoresist.  The use of an inter-mediate mask and focusing lens  enables the formation of a diffraction grating within a limited area.  A blazed diffraction grating may be formed by splitting a laser beam into two beams having an increased beam radius, and irradiating a light-sensitive material with the resulting two beams to form an interference fringe.  This method is characterized in that in a first exposure the two beams are incident on the light sensitive material through air to form an interference fringe having a clearance width of d, and in a second exposure, the two beams are irrad-iated on the light sensitive material through a symmetri-cal transparent member having an isosceles triangular cross section in such a manner that the origin coincides to form an interference fringe having a clearance width of d/2, and furthermore, in that the ratio of the first exposure energy to the second exposure energy is made equal to the ratio of the first term to the second term of a Fourier series obtained by expanding the periodical function of the waveform of the blazed diffraction grating.     An optical branching filter element comprised of a sub-strate having a wave guide thereon of a material capable of reversibly changing its refractive index may have a diffraction grating formed in the waveguide by either of the disclosed methods.  The grating may be erased by the selective application of infrared light, electric current or heat.
