Title: Intercalation of graphitic carbon  fibers
Inventor: KALNIN ILMAR L
IPC: D01F9/22
Filed: 1980-02-08
Granted: 1982-11-23
Abstract: Abstract of the Disclosure The formation of improved intercalated graphitic carbon fibers of further diminished electrical resistivity (i.e., increased electrical conductivity) is made possible.      Not only is the specific electrical resistivity of the resulting fibers reduced (e.g., to extremely low levels no greater than that of copper in preferred embodiments), but the desirable tensile properties of the fibers are maintained at a satisfactory level even after intercalation.  A carbon-aceous fibrous material containing the usual turbostratic graphitic carbon which is derived from an acrylonitrile homopolymer or a closely related copolymer (as defined) is selected and is structurally modified in a manner which has been found to render it particularly suited for intercalation as evidenced by a further reduction in the electrical resis-tivity of the resulting intercalated fibrous material while retaining other desirable properties.  More specifically, the carbonaceous fibrous material (as defined) prior to intercalation with an electron acceptor intercalating agent is modified via an atypical extremely high temperature treatment so as to yield a modified structure which can be evidenced upon wide angle x-ray diffraction analysis, i.e. resolved graphitic Miller index (100) and (101) reflections and the presence of a (112) reflection are observed, which surprisingly has been found capable of subsequently yielding an improved intercalated product having a substantially reduced electrical resistivity.  The intercalated product finds utility as an improved ligtweight electrical conductor.

Abstract: ABSTRACT OF THE DISCLOSURE     A method for the automatic, electro-chemical determination of the end point of titration utilizing an initial, continuous addition of the ti-trant, up to a predetermined value, followed by a step-by-step addition with a resting time inserted therebetween for stabilization of the solution is disclosed.  As the titrant is being added to the bath sample in constant volume units, a measured value is formed after every such addition.  The difference to the preceding measurement is determined and the three consec-utive differences of greatest magnitude are utilized in a mathematical for-mula for calculating the end point.  The titration ceases when the greatest difference lies between two lesser values.

Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus is provided for preconditioning and pre-heating pellets of glass batch prior to heating and melting them in a furnace.  Components of glass batch are mixed together and combined with water to form agglomerates, e.g. pellets.  These agglomerates are supplied to a hopper through which hot com-bustion gases are passed and they are preheated to an elevated temperature in the hopper prior to entering the melting furnace, thereby resulting in a savings of substantial amounts of energy.    Moisture is removed from the agglomerates prior to their being supplied to the hopper; hence, the tendency for the agglomerates to adhere to one another and form aggregates, or clinkers, is substantially controlled.  For that purpose, the agglomerates are collected in a preconditioner having a receptacle located above the bed of agglomerates in the hopper with the hot gases also passing through the agglomerates in the receptacle after passing through the bed in the hopper.  After moisture is re-moved, the agglomerates are dropped from the receptacle onto the bed in the hopper.  The agglomerates may be melted in a com-bustion fired melter or in an electrically powered melter.

Abstract: Abstract:   The present invention relates to a panel assembly for use as a door or as a section of a wall.  The assembly consists of a substantially rigid, prefabricated frame of exact rectangular or square shape, and a main framework formed around the prefabricated frame from interconnected elongate framework members.  The prefabricated frame and the elongated framework members have tongue and groove connection means.  The prior exact configuration of the prefabricated frames facilitates location of the elongate framework members snugly around the prefabricated frame to form an exact main framework.  The use of a substantially rigid prefabricated frame considerably assists the assembly of the panel without requiring careful measurement and orientation of the elements.

Abstract: ?FN 6781 IMPROVED INK JET PRINTER          Abstract of the Disclosure An ink jet printer includes a print head means which generates two parallel rows of jet drop streams.  Charge electrodes are mounted on a pair of charge electrode plates which are movable into and out of drop charging positions.  A pair of catchers each define a drop catching surface and a drop ingesting slot along the lower edge of the drop catching surface.  Each of the catchers is generally pivotally mounted for rotation about an axis parallel to the rows of jet drop streams.  The catchers may be pivoted from a drop catching position, in which the drop catching surfaces are substantially parallel, to a full catch position in which drop catching surfaces are inclined to face upward and intercept the jet drop streams.  In the full catch position, the drop ingesting slots are positioned closely together.  A linkage arrangement is provides for pivoting the catches from the full catch position to the drop catch position after star. up of the print head means.  The linkage arrangement also moves the charge electrode plates into the drop charging positions after the catchers are pivoted sufficiently to apply a drop deflecting potential to thereto, but while the drop catching surfaces intercept the jet drop streams.

Abstract: ABSTRACT OF THE DISCLOSURE The invention concerns a three- or four-stage gas compressor comprising two interconnecting compression units operated by hydraulic pistons.  The first unit comprises a central hydraulic section flanked by two identical and symmetrical lateral sections each incorporating the first and third stages and operated by an alternating hydraulic piston.  The second unit comprises a central hydraulic section of lesser diameter than that of unit one but with equal volume of oil, and two lateral sections similar to those of unit one but of lesser diameter.  In the four-stage embodiment the lateral sections of unit two comprise between them the second and fourth compression stages, whilst in the three-stage embodiment the lateral sections of the second unit comprise only a single section each of the second compression stage.  The oil chambers relative to each unit's central section interconnect - in either embodiment -by way of a compensating valve.  For each single stroke of the first compres-sion unit's piston in central section, the corresponding piston in the central section of the second unit completes a contrariwise single stroke.  The consumer unit thus receives a delivery of gas per single stroke of the piston in the first unit's said central section.
