Abstract: Replaceable Fastener for Cover Plates And The Like Abstract The push frame of a tractor-scraper normally has a plurality of cover plates releasably secured therebelow to provide access internally of the push frame.  In standard practice, the cover plates are secured to the push frame by a plurality of bolts and the heads of the bolts are subjected to wear and possible breaking-off due to their exposure upon opera-tion of the tractor-scraper.  This invention provides a mounting assembly for expeditiously removing and replacing the cover plates upon wearing or breaking-off of the heads of bolts thereof by providing an intern-ally and externally threaded bushing which is thread-ably connected on the push frame and is further threadably connected to each bolt.  Thus, a workman need only engage the bushing with a socket wrench or the like to release the bolt and thus the cover plate upon wearing or breakinq-off of the heads of the bolts.

Abstract: TITLE:  FLOW LINE MONITOR PILOT VALVE ASSEMBLY     ABSTRACT OF THE INVENTION A control fluid valve assembly is provided which is respond-able to a pressure monitored fluid.  The assembly preferably comprises first and second valve seats within a housing.  A spool element is shuttleable within the housing near the valve seat by either manual or mechanical manipulation to first and second positions and is responsive to pressure variation within the monitored fluid to shuttle it to a second position.  Balls are contained in first and second valve head groups and are carryable by the spool element, the balls being selectively sealingly en-gagable onto and wipable off of the valve seat means to control fluid flow of the control fluid within the assembly in response to the pressure monitored fluid.  A plurality of seals are defined between the housing and the spool means to prevent fluid communi-cation therebetween and to define flow passageways  across the spool.  The spool is shiftable to each of first and second posi-tions and when in one of the positions pressure is substantially equalized within the flow passageways and the spool is statically stabilized.  When the spool is shiftable to the other position, pressure differential defined across one of the seals urges and holds the spool in this second position.  A control shaft is provided which is selectively communicable to the spool for shuttling the spool in one direction to one position.  Piston means are provided which are responsive to predetermined increase and/or decrease in pressure of the monitored fluid for shifting the shaft to shuttle the spool.  The apparatus may be selectively calibrated to respond to at least one of high and low pressure tolerance to cause shuttling of the spool to manipulate the balls with respect to the seats to vary the flow passageways within the valve and to selectively open and close, for example, a sub-surface safety valve within a subterranean oil or gas well.

Abstract: ABSTRACT OF THE DISCLOSURE         Textile quality polymeric fibers and thin films that are highly sorbent for organic and other vapors, mists and solutes.  The fibers and films comprise a polymeric matrix with a system of interconnecting micropores, and are highly loaded with particulate sorbents such as activated carbon.  The fibers and films are manufactured by forming a melt blend of the sor-bent particles, the polymer and a selected diluent, spinning or extruding and drawing down the fiber of film, and extracting the diluent.  The diluent functions to permit a high spin or extrusion draw down, to permit the subsequent cold drawing of fibers highly-loaded with active carbon, and to permit the fiber or film to be porosified.  Optionally, the diluent may be extracted after or before cold drawing, or without any cold drawing.  The fibers and films are highly sorbent, are strong and durable and exhibit substantial strength over an appreciable degree of elongation.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention relates to improvements in air seeders, namely agricultural implements which utilize air pressure to move particulate material such as seeds from a feed zone to a dispersal or planting zone.  The particulate material is normally fed from a hopper by a driven feed wheel or other similar mechanism.  The invention provides an electrical pressure-sensitive transducer at the source of air pressure, a circuit connecting the transducer with an electrically-operated actuator and a suitable linkage connecting the actuator with a clutch which is used to transmit drive power to the feed wheel.  As long as there is sufficient pressure at the source the actuator will keep the clutch positioned to permit the feed wheel to operate.        Should the pressure source fail the actuator will operate the clutch to stop transmitting power to the feed wheel and thus terminate the feeding of material which would otherwise clog the delivery conduits of the seeder.

Abstract: ABSTRACT OF THE DISCLOSURE            Sheet deliverer for rotary printing machines with gripper shoe flies 12 running on continuous chains.  The chain line features a rising and a horizontal section 6,7.  A sheet guide plate 9 is installed under the rising section 6.  The horizontal section 7 of the chain line runs above the delivery pile 8, directly upstream of which are braking rollers 14.  A line of guide yoke blowers 12 are positioned above the upper, curved guide plate end 10.  The guide yokes 11 of these blowers run in the feed direction of the sheets and their blower nozzles 13 deliver an air stream which is directed against the sheet feed.  The air leaving the blower nozzles 13 creates a partial vacuum, which causes the underside of the sheet to be sucked against the guide yokes 11 of the guide yoke blowers 12 at points free of print, thus ensuring reliable application of the underside of the sheet onto the braking roller 14.  Both braking roller 14 and blower nozzles 13 are installed so that they can be laterally adjusted and can, therefore, be aligned with positions on the sheet which are free of print.

Abstract: THERMAL TRANSFER PRINTING METHOD    AND PRINTING PAPER THEREFOR     ABSTRACT OF THE DISCLOSURE     In a thermal transfer-type printing method in which an image is formed on printing paper by the selective transfer thereto of disperse dye from a dye carrier of flexible sheet material in response to the selective appli-cation of thermal energy to the carrier while in contact with a surface of the printing paper, the latter is comprised of a base of cellulose fibers and resin into which the disperse dye diffuses for producing a clear definition of the image.  The resin is desirably polyester or acetyl cellulose either in the form of fibers which are co-mingled with the cellulose fibers in the base of the printing paper, or in the form of a coating on a surface of the paper base.          After the image has been formed by thermal transfer on a surface of the printing paper, a thin transparent film, preferably of polyester, is laminated over the printed surface by a polyester adhesive and the application of heat and pressure so that recrystallized disperse dye remaining on the surface of the printing paper is further diffused into the polyester adhesive.
