Abstract: TITLE: AIR COOLED DOOR HANDLE FOR HEATERS INVENTORS:  Carrol E. Buckner C. Glen Cook Thomas J. Kane ABSTRACT OF THE DISCLOSURE     The door handle of a heating unit is cooled by providing a duct traversing the interior of the handle from exterior of the firebox of the heating unit to the interior of the firebox.          The induced flow cools the handle and provides cool air in the firebox to trap and maintain the hot gasses closer to the fire for a more complete combustion.  An open, ellipsoid, spiral coil surrounds the grip of the handle.

Abstract: METHOD OF OBTAINING FACTOR VIII     ABSTRACT A method of obtaining Factor VIII which comprises adding heparin to freshly obtained blood plasma collected into a calcium chelating anticoagulant or collecting blood plasma by plasma pheresis using heparin and a calcium chelating anticoagulant; freezing the plasma; resolubilizing the plasma; isolating a cryoprecipitate from the plasma; resolubilizing the cryoprecipitate; adding a citrate saline heparin buffer to the resolubilized temperature of from about 0°C for a time in excess of about one hour, whereby Factor VIII present in the cryoprecipitate is insolubilized using heparin precipitable cold insoluble globulin; separating the Factor VIII rich precipitate; and isolating Factor VIII therefrom.  The introduction of the cold insoluble globulin (CIg) step to Factor VIII production results in markedly increased yields of Factor VIII in the cryoprecipitate and, as well, in the cold-insoluble globulin obtained from the cryoprecipitate.  Using this procedure, 81% of the Factor VIII is recovered in the cryoprecipitate.  The cold-insoluble globulin contains 62% of the starting Factor VIII activity.  A final recovery of 666 units per litre of starting plasma is therefore obtained and the amount of protein is reduced to less than 1%.  In addition, the procedure can be carried out in blood donor centers, although it is also envisaged to be useful in larger scale recovery of Factor VIII procedures.

Abstract: ABSTRACT OF THE DISCLOSURE           A flow of fermenting liquor from a fermentor is separated into a yeast concentrate flow, which is recirculated to the fermentor, and a yeast-free flow which is separated in a simple evaporator unit into a first ethanol-enriched vapor flow and a first liquid bottom flow.          The first vapor flow is treated to produce the desired ethanol while a major part of the first liquid bottom flow is recirculated to the fermentor.  A minor, residual part of the latter flow is fed to a stripping unit where it is separated into a second ethanol-enriched vapor flow and a second liquid bottom flow exhausted of ethanol.

Abstract: WIND POWER SYSTEM        Abstract of the Disclosure A wind motor includes three vanes mounted to rotate about a vertically oriented main shaft, and the three vanes are also mounted to rotate about individual axes which are equidistant from  the main  shaft  and extend  parallel  to  it.   Through  the  use  of cranks connected to each vane, and a simple triangular linkage interconnecting  the  cranks,  the  three  vanes  rotate together so that, as the wind impinges on the system, all  three vanes cooperate to aid in rotation of the assembly around  the main shaft.   A collapsible unit includes arrangements for unfolding the vanes  as the main shaft is raised into operating position.  The wind motor is preferably located in an area where winds are funnelled at relatively high velocity to impinge on the wind motor.   The vanes of the wind motor are oriented by a cog belt or a sliding rod,  for optimum angular orientation  with  the  wind,  and  arrangements  are provided for holding the vane control assembly in this optimum orientation.

Abstract: UNITED STATES PATENT APPLICATION              OF :  LESTER E. BURGESS, KARL M. FOX, PHILLIP E. MCGARRY and DAVID E. HERMAN       FOR:  IMPROVED PROCESS FOR BENEFICIATING COAL               ABSTRACT OF THE DISCLOSURE         Beneficiated coal and a process for beneficiating coal are provided.  Mined coal is pulverized in the presence of water to form a particulate coal aqueous stream.  The extended surfaces of the particulate coal are rendered hydrophobic and oilophilic (oil loving) in a chemical graft polymerization reaction wherein a polymerizable organic monomer is utilized to render the parti-culate coal hydrophobic and oilophilic.  The reaction occurs in an aqueous medium in the presence of free radical polymeric cata-lysts and initiators and a fuel oil.          Mineral ash and sulfur normally present in the coal are separated from the treated coal in a water washing step.  The un-wanted impurities are removed in a water stream.  The chemical treatment and the washing step can be effected in a unitary operation.          The recovered coal particles can be dried to remove excess water.  Such drying can be effected using simple mechani-cal dryers.          The beneficiated particulate coal can be burned as a fuel, or it can be admixed with oil to form a coal-oil mixture. A salt forming compound and a chemical treatment step are pro-vided to stabilize the coal-oil mixture.         The resultant coal-oil mixture is beneficiated and stable for extended periods of time.

Abstract: Abstract of the Disclosure A subscriber line interface circuit is described wherein the transverse and longitudinal termination impedances may be independently controlled; and wherein the equivalent termination impedance of a subscriber line/trunk as appears to the central office can be adjusted upward or downward from a lower resistance value, with longitudinal balance (also known as the common mode rejection) being determined by the matching of feed resistors.  The foregoing interface circuit is implementable as a monolithic integrated circuit having low power dissipation, improved power bandwidth requirements, and lower voltage breakdown requirements for integrated circuits; all resulting in an improved telephone line interface circuit.  Voltage feedback or current feedback may be employed in a circuit to synthesize the proper ac transverse termination impedance from a known dc resistance, for example, from the feed line resistors in a telephone line circuit.

Abstract: Abstract A drivable roll, with controllable deflection or bow, more particu-larly for machines for the production and processing of paper or plastic in strip form has a cylindrical inner part (1) mounted stationarily upon supports (5) by means of trunnions (2), and a tubular outer part (3) mounted rotatably upon the inner part.  Arranged upon the latter, along a generating line, are means for producing constraining forces acting radially between the inner and outer parts.  Passing coaxially through one trunnion is a drive-shaft (6) mounted upon the trunnion and inner part, the drive-shaft being integral with a central gear (10) which, through an intermediate gear (11), drives an inter-nally toothed ring (14) frictionally connected to the outer part (3) by clamping elements (15a,15b).  The axis of rotation (Z) of the intermediate gear (11) is parallel with the drive-shaft (6), the teeth (11a) of the intermediate gear having crowned crests arching in the direction of its axis of rotation (Z), towards the end-faces.  The structural cost of the drive is low, and high load-ings can be withstood even with small-diameter trunnions Moreover when the outer part of the roll is deflected, this has no detrimental effect upon the drive.
