Abstract: Abstract A combined document cover and document storage assembly for a copying machine which copies both flat sheet documents and thick book documents. The document cover is hinged to the copyier along the edge remote from the operator so that the operator lifts the cover in an upward and rearward arcuate movement. The cover has a document holding pocket along the upper rear edge thereof for receiving the edges of a stack of documents placed on the cover to hold the documents in place when the cover is lifted, the pocket having a slanted wall in order to cause the documents to overlap each other by a small amount to facilitate grasping the uppermost document. The cover cooperates with the top wall of the housing of the copying machine is order to permit stacking of the documents after they have been copied in a manner which permits checking each successive copy with the original to be sure that the document is copied and to facilitate restacking of the documents in order corresponding to the order of the copies as these are stacked in exiting from the copying machine.

Abstract: ABSTRACT OF THE DISCLOSURE     An apparatus for improving the heating characteristics of a fireplace for an enclosed area is disclosed.  A heat exchange conduit extends concentrically through the chimney for a distance and the connects at one end to a ducting system having at least one outlet within the area to be heated.  The other end of the conduit is connected with a plurality of bent arms which are positioned in the firebox and they, in turn, con-nect with a manifold pipe.  The manifold pipe is a horizontal member having heat sensitive valves in the ends thereof, and orifices along the length thereof directed toward the firebox.  A fan is positioned within the ducting to pull air primarily from the enclosed area and force it through the conduit.  This construction improves the operating characteris-tics of the fireplace by employing hot flue gases to preheat air to be circulated within the work space and forces circulation of air from the work space through a heat transfer area and back into the work space.  If the temperature in the work space is below a preset value, air is directed into the fire to increase heat output.  This, thereby, improves the opera-ting characteristics of a fireplace.

Abstract: A METHOD OF TRANSPORTING LIQUID PITCH          CONTAINING COKE AND APPARATUS THEREFOR            Abstract of the Disclosure A method is disclosed of transporting liquid pitch containing coke lumps wherein the coke contained in the liquid pitch is pulverized by a specific procedure and the pitch con-taining the thus pulverized coke is then transported.  Specific apparatus used for carrying out the method is also disclosed.          The specific procedure involves introducing the liquid pitch from a reactor for the thermal cracking of heavy petroleum or the like into a reception vessel, allowing the lumps of coke to settle to some extent, removing some of the pitch from a side of the vessel through a strainer, coarsely grinding the settled lumps between a rotating blade and a perforated plate at the bottom of the vessel, removing some of the pitch and ground lumps through the perforated plate, grinding the removed lumps more finely in a pulverizer, and mixing the finely ground lumps and associated pitch with the pitch removed from the side of the vessel and then finally transporting the resulting mixture normally.  In this way, the clogging conventionally produced by the coke lumps during transportation can be avoided.

Abstract: ABSTRACT OF THE DISCLOSURE A diverless subsea flowline connection system includes connectors for remotely connecting the ends of a first bundle of flowlines to the ends of a second bundle of flowlines and guidance components which direct the end portions of the first bundle of flowlines into precise connecting alignment with the end portions of the second bundle of flowlines without damage to the connecting seals.          The ends of the first bundle are covered and sealed so that the flowlines can be pulled across the seafloor without damage to the ends of the flowlines.  Means are provided for pulling the first bundle toward an alignment structure so that the lines can approach the structure from a wide variety of angles and the structure will guide the first bundle into exact alignment with the second bundle.  This pulling means includes means for connecting a pulling cable to the radial center of a pulling head attached to the ends of the first bundle of flowlines.  The ends of the flowlines are connected together and aligned before the fluid-tight seals are set to prevent possible damage to the seals.  After the flow-line ends are precisely aligned the seals are set. If desired, the connecting seals can be replaced by remote control.  The pulling, aligning, replacement of seals and fluid-tight connecting of the flowlines is all done by remote control from the surface of the sea.                     -1a-

Abstract: ABSTRACT OF THE DISCLOSURE       This invention relates to a dual control mechanism for a skid-steered tractor vehicle is driven by right and left hydrostatic transmissions having separate steering levers, one for each transmission.  A centering device acting directly on the transmission controls is longitudinally shiftable against the force of a spring in response to pivotal movement of either steering lever from a neutral or idle position for returning the steering lever upon release.  The dual control mechanism is interposed between the outer end of a rotatable shaft and the lower end of one of the steering levers.  The dual control mechanism enables the steering lever to be operated in a first plane to engage one of the drive means, and in a second plane perpendicular to the first plane to control auxiliary functions without interfering with the steering function of the lever.
