Abstract: ABSTRACT OF THE DISCLOSURE         The disclosure relates to a finishing treatment for fabrics, particularly tubular knitted fabrics, having at least some natural fiber content, where the fabrics have been given a compressive shrinkage treatment by an asymmetrical process, some-times referred to herein as "burnish compacting", in which one side of the fabric is acted upon differently than the other.  The process and apparatus of the invention eliminate or minimize "two sidedness" in the appearance of the fabric, which otherwise can be particularly noticeable with respect to colored fabrics.  After passing through an asymmetrical compressive shrinkage process, the fabric is conveyed in a tension free manner through a moisturiz-ing station, in which moisture is sprayed on the opposite surfaces of the fabric in the form of an extremely fine fog or mist, in quantities greater than the natural moisture regain of the fabric after compacting.  The thus-moisturized fabric immediately enters a so-called Palmer-type dryer, in which the fabric is held against a steam-heated drum by means of a porous blanket.  Significant improvement in the opposite side uniformity of the fabric is obtainable by the process.

Abstract: ABSTRACT         A muffler for small internal combustion engines, such as for a chain saw, is disclosed.  The muffler has a chamber enclosed by a chamber wall and a dished housing wall.  The housing wall contains an inlet for the exhaust gases.  A gas duct is arranged on the inside of the chamber wall and deflects the gases through at least 90° before exhausting them through an opening in the chamber wall.  The gases then pass through an elbow that de-flects them further and along the surface of the chamber wall to an element perpendicular to their paths, to impact turbulence.

Abstract: ABSTRACT OF THE DISCLOSURE           A process is disclosed for the selective extraction of arsenic from oxidic materials containing compounds such as arsenic trioxide, arsenic pentoxide, antimony trioxide, antimony pentoxide, antimony tetroxide and mixtures thereof in which arsenic is effectively separated from antimony.  Said oxidic materials are subjected to a leach with a lixiviant containing arsenic acid or hydrogen peroxide at a temperature in the range of 40°C to the boiling point of the reaction mixture, preferably in the range of 80 to 100°C, for 5 to 90 minutes.  The leach solution containing arsenic oxides is separated from leach residue.  The leach solution is either cooled to a temperature in the range of 5 to 25°C to crystallize and subsequently recover arsenic trioxide or the solution is oxidized and evaporated and arsenic pentoxide is recovered.  Arsenic acid lixiviant contains 5 to 500 g/l arsenic as arsenic pentoxide, preferably 25 to 200 g/l, and hydrogen peroxide lixiviant preferably contains a 10 to 60% hydrogen peroxide concentration.

Abstract: Abstract of the Disclosure The bore of a glass tube is coated with a layer of cladding glass. By introducing glass forming vapor reagents into the bore of the tube and heating the reagents with a heating excitor moving relative to the tube. The reagents proximate the heating excitor are converted to glass on the inside of the tube.  The relative movement between the tube and excitor causes the glass layer to be uniform.  In usual practice, the layer of cladding glass will be of equal or higher refractive index than that of the tube.  A second layer of core glass of higher refractive index than that of the first layer may be deposited on the first layer.  The conted tube is drawn into a fibre while collapsing the bore to form a solid core that may be surrounded by cladding.

Abstract: METHOD FOR GENERATING STEAM       (D#73,500-RCA-40-F) ABSTRACT OF THE DISCLOSURE         Disclosed is a method for generating steam from water containing high concentrations of particulate matter such as silt, clay, etc., without the need for filtering and otherwise treating the water prior to generation of steam therefrom,  especially useful for use in a viscous oil recovery process.   The method comprises introducing solid particulate materials such as coarse sand, etc.,  into a thermal cracking unit such as, for example, that is used in the Lurgi-Ruhrgas process.  The solids are heated to a temperature of at least 1400°F, and on contacting the crude, cause cracking of the viscous crude into lighter molecular weight hydrocarbons and form a solid coke-like residue on the sand grain.  The sand grains containing the coke residue are transported into a second chamber into which air is injected and the solid coke residue ignited.  The carbon coke residue burns, raising the temperature of the sand or other granular solids.  A portion of the hot solids are recycled into the thermal cracking unit, and another portion are transported to a steam generator unit into which dirty water, e.g., water containing high concentrations of suspended particulate matters such as sand, clay, silt, etc. is introduced.  The rate of hot solids introduction and water injection into the steam generating unit are controlled so as to produce steam of the desired quality for use in a steam injection viscous oil recovery method.                             -I-

Abstract: Abstract of the Disclosure A beam index color cathode ray tube has index stripes spaced apart across a run-in area of the screen and which have a pitch substantially equal to the pitch of index stripes in an image area.  A plurality of the index stripes in the run-in area generate an index signal as an electron beam scans them.  An index stripe is omitted from the portion of the run-in area nearest the boundary with the image area to provide a characteristic to the index signal which permits generation of a trigger signal to preset color control circuits to a known condition as the electron beam enters the image area.  A gating circuit blocks trigger signals which may be generated during scanning of the image area.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention relates to shower fittings especially those used in the paper and board making industries.  Prior art fittings include jets for directing streams of treatment liquid towards a surface to be treated, the jets being mounted upon a liquid supply tube that is reciprocable longitudinally across the surface.  The invention is concerned with the problem of ensuring adequate support and protection for the tube and jets. The liquid supply tube carrying the jets is located within another outer tube and is movable on supports carried by that tube.  The outer tube has a longitudinal slot in its wall through which emerge streams of liquid discharged from the jets which, for protection are also housed within the outer tube.  The invention is distinguished from the prior art by the manner in which the inner tube is mounted and arranged inside the outer tube to provide the necessary protection of the jets.

Abstract: ABSTRACT    Subscription  apparatus and methods wherein an encoder begins inversion of a video signal during the last horizontal trace line of a randomly selected vertical interval and continues to invert trace lines in the following field of the video signal. The encoder also suppresses the amplitude of randomly selected horizontal blanking pulses only during fields of the video signal while maintaining unaltered the absolute amplitude differential between the horizontal blanking pulses and associated horizontal synchronization pulses. A decoder reinverts trace lines of the field following detection of an inverted last horizontal trace line of a vertical interval. The decoder also selectively rebiases the video signal to restore the horizontal blanking pulses upon detection of a suppressed amplitude during the front porch of a horizontal blanking pulse. Reinversion of the trace liens and rebiasing of the blanking pulses is achieved by selective reference biasing of a video modulator circuit in the decoder.
