Abstract: INTERCONNECTION FOR CONDUCTOR ASSEMBLIES HAVING CLOSELY SPACED CONDUCTIVE LINES                      ABSTRACT    A set of closely spaced, parallel conductive lines on an insulating support are located in face to face electrical con-tact with a corresponding set of conductive lines on a second insulating support, and a new structure is provided for ad-justing the two sets of lines to match properly despite vari-ations in the spacing between the lines of a set.  The first set of lines has close, even, spacing.  In the second set, the lines converge slightly from a spacing that is wider than the spacing of the first set to a spacing that is narrower than the spacing of the first set.  During assembly, the position where contact occurs between the two sets is adjus-ted so that satisfactory electrical contact is made between each pair of lines.

Abstract: ABSTRACT OF THE DISCLOSURE         According to the device of the present invention, it is possible to accomplish ignition, stifling of flames, and exposure and concealment of the flame adjusting portion and feed valve by a simple operation of merely pushing ox turning the fore cylinder of the device.  Also, since the feed valve and other internal parts are covered up within the casing, the external appearance of the device is not impaired and the feed valve is protected against external impact.  Further, since the feed valve is secured directly to the gas container, the required space can be minimized, thus realizing an ideal pencil-shaped gas lighter which is small in size and very handy to carry.

Abstract: Abstract of the Disclosure Rotary motion is converted to linear motion by multiple thread sets which cooperate to provide precise control of the amount of rotary motion thus converted.  As applied to a precision positioning device for a tool, blade or other object, the thread sets are preferably arranged in a serial and/or telescop-ed configuration.  A relatively simple precision hand tool positioning device is realized by having one thread set arranged in a common direction but reduced pitch re-lative to the other set.  The finiteness of the object positioning is further enhanced by moving it with res-pect to an inclined plane.  A retaining device for grip-ping the element to be moved is directly associated with a shank having the smaller pitched thread set thereon.          The shank is prevented from rotating but allowed to move linearly relative to a housing and the threads thereof engage a spindle which has another set of threads for engaging the housing.  A calibrated indicator of the shank position in easily readable format is provided.          A split collet for the shank with a spring biased collet clamp and actuator is particularly well-suited for use as a tool chuck especially useful for calibrated craftsman knives.  A detent arrangement can be included with the housing.

Abstract: ABSTRACT OF THE DISCLOSURE         A shuttle valve is situated between the service brake and emergency brake lines downstream of the brake control valve which modulates both lines.  The shuttle valve includes a dif-ferential pressure piston in a cylinder.  The piston includes a large diametered end connected to the service brake line and a smaller diametered end connected to the emergency brake line with a port in the side of the cylinder adjacent the small dia-metered end.  The air pressure in the service brake line acts upon the large diametered end of the piston and normally main-tains the piston at one end of the cylinder so that the port is closed off by the small diametered end of the piston.  However, if the service brake pressure drops below a predetermined min-imum, the piston will move in the cylinder thus uncovering the port and connecting the emergency brake line to the emergency air tank.  When the fault is corrected and the pressure builds up in the service brake line, the air pressure acts upon the pis-ton and moves it in the opposite direction thus shutting off the aforementioned port and disconnecting the emergency brake system.

Abstract: PULL-OUT FOLDING SOFA REDS     ABSTRACT OF THE DISCLOSURE        This bed comprises a front forwardly extending foot section having rearwardly extending side arms.  Said side arms have similar, symmetrically disposed, horizontal offset portions raised above the horizontal plane of the bed mattress supporting fabric of the bed platform when the bed is in open sleeping position.  In the closed position of the bed, the foot section projects rearwardly and said offset portions are then disposed below the horizontal plane of the mattress supporting fabric and hence in a depressed plane.  The fabric is connected to each of a pair of zig-zag springs disposed alongside said depressed portions (in the closed position of the bed), at points disposed inwardly of the ends of the zig-zag springs, and also by a pair of helical tension springs to the side arms, at locations beyond the outer ends of said depressed portions.  With such construc-tion, persons sitting at the ends of the sofa (when the bed is closed) have a softer, more comfortable seat, because of the depressed side portions of the foot section and because of less tension on the fabric, and also more relaxing, softer seating between the ends of the sofa, because of use of less helicals to connect the fabric to the bed frame at the sides of said foot section.  The ends of the zig-zag springs are furthermore re-ceived in the end helical springs on each side of the foot section to house and encase said ends.

Abstract: ABSTRACT OF THE DISCLOSURE   An improved process is provided for preparing ethyl vanadate.  The process includes reacting vanadium oxytrichloride with ethanol under sub-stantially anhydrous condition in a mole ratio of vanadium oxytrichloride to ethanol of from 1:1 to 1:6 and at a temperature of from 0 to 80°C in the presence of ammonia.  The improvement involves conducting the reaction in the presence of a hydrocarbon solvent and includes the subsequent step of adding an amide selected from the class consisting of formamide and methyl formamide which forms two liquid phases, one phase containing the ethyl vana-date and the other containing the undisolved ammonium chloride, the hydro-carbon solvent being immiscible with the amide, and being a nonsolvent for the ammonium chloride.  The ethyl vanadate need not be separated by a pro-cess requiring prolonged heating thereby causing degradation of the ethyl vanadate, or  by filtration, wherein ammonium chloride has a tendency to plug up the filter, but may be readily separated from the ammonium chloride-amide layer by any other conventional technique known in the art.
