Abstract: ABSTRACT      Disclosed is a conventional apparatus for directing molten, mineral slag onto a spinner rotating on a horizontal axis with annularly arranged steam jets directed parallel to the rotational axis stripping the slag from the spinner and fiberizing it.  This conventional fiber forming system is utilized with a collecting tube having a conical entry portion which is concentric with and faces the stream of fiberized material projected by the steam jets.  The spacing of the mouth of the entry portion from the point of entry of the slag into the steam jets is such as to minimize entry of shot or unfiberized slag into the collecting tube.  The fiberized material is further refined or stripped of unwanted particles by passing it through an inclined portion of the collecting tube and, sequentially, through two, cyclone-type centrifugal separators before collecting it in a conventional bagging apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE        A process for bleaching lignocellulosic material such as wood pulp by treatment with a mixture of nitrogen dioxide and nitric oxide, the nitric oxide being present in molar excess. The treatment with nitrogen oxides is followed by washing and treatment with caustic. Treatment with oxygen under supra atmospheric pressure may precede or follow the treatment with mixed nitrogen oxides. The substitution of nitrogen compounds for the chlorine-containing compounds normally employed in the bleaching of wood pulp reduces the level of polluting materials in the effluent of a pulp mill employing the process.

Abstract: TITLE   A METHOD OF RECLAIMING WATER AND COAL FROM COAL TREATMENT    UNDERFLOW BY TWO-STAGE SEPARATION OF SOLIDS     ABSTRACT OF THE DISCLOSURE            Water as well as coal are reclaimed from an aqueous slurry of coal and ash fines by first adding to an aqueous slurry of coal and ash fines a liquid lyophobic to water and ash and lyophilic to coal to form a first mixture.  Preferably, the processed aqueous slurry is formed by mixing a low solids aqueous slurry of coal and ash fines from a coal washer with a high solids aqueous slurry of coal and ash fines from a settling pond.  The first mixture is then agitated to agglomerate the coal fines, and the agglomerated coal fines are separated from the mixture to form a substantially non-coal aqueous slurry.  A preferably high molecular weight flocculant lyophobic to water and lyophilic to ash is thereafter added to said non-coal aqueous slurry to form a second mixture, and flocculated solids precipitated from the second mixture to separate water from the second mixture.  Flocculated solids are then separated from the second mixture to form a substantailly solids-free aqueous solution.  Preferably, the separated water is recirculated to a coal washing plant, and the solids-free aqueous solution is recirculated to the second mixture, or a coal washing plant, to form a closed water system for a coal washing plant.

Abstract: ABSTRACT             An apparatus and method for forming foundry cores and molds of superior hardness and uniformity in a wide range of sizes includes staging hoppers for storing a first mass of sand coated with a catalyst-polymerizable resin film, and a second mass of sand coated with a catalyst filmfor polymerizing the resin.  In forming the cores or molds these masses are simul-taneously and evenly dispersed and directed through a static mixer stage, wherein the resin and catalyst-coated sand par-ticles are intermingled and at least a partial integrationof the films takes place, into a shaping mold cavity, wherein the sand mixture hardens into a desired shape.  Because the process is fast and continuous and mixing is accomplished without mechanically driven mixing elements, the apparatus and method are particularly well suited to high volume foundry operations wherein resin-catalyst systems having very fast hardening times are utilized.

Abstract: ABSTRACT OF THE DISCLOSURE          This invention relates to a method and apparatus for making electrical contacts.  According to the method, a length of contact forming material is guided along a prede-termined path toward a cutting device and a welding device.  A contact piece is cut from the forward end of the length of the contact forming material by the cutting device and is then advanced into engagement with one electrode of the welding device. The contact piece is then elevated into contact with a contact carrier arranged below a second electrode and the contact piece is welded to the carrier.  The apparatus in-cludes a cutting device which is adapted to cut a contact piece from the length of contact material.  A guide is pro-vided for guiding the strip of contact material to the cutting device.  An electrical resistance welding device is spaced from the cutting device for welding  of a cut contact piece to a contact carrier.  A second guide is arranged between the cutting and welding devices for guiding the contact material from the cutting device to the welding device.  The first and second guides are connected in alignment.  The welding device has a first stationary electrode and a second electrode which is arranged below and movable toward the first electrode.  A holder is provided for holding the contact carrier at the under side of the first electrode.  The second electrode has a groove for receiving a lower part of the contact piece and is liftable from a rest position in which the groove is connected in align-ment with the second guide to a welding position in which it is pressed toward the first electrode.  A gripping device is pro-vided to grip and move the remaining length of contact material and a drive mechanism is provided for actuating the cutting de-vice, gripping mechanism and the second electrode.

Abstract: 04-4091-U.S.     APPLICATION OF               ROBERT J. HANDLY & ROBERT H. DOUGLAS     MICROCOMPUTER APPARATUS     ABSTRACT     A computer system features a processor unit which includes its own microprogram control unit.  The microprogram control unit includes a storage means for operational instructions for the processor unit and means to issue those instructions in a desired sequence.  A communication Bus provides communication channels between the processor unit and either data storage means or other processor units served by the Bus.  The processor unit includes a number of clock controlled functional components as well as means for requesting access to the Bus.  A clock signal generating means is controlled by signals from the microprogram control unit.  When a request has been made for access to the bus, the processor continues to operate until a point is reached when access to the Bus must be accomplished before continuing.  The microprogram control unit issues a control signal which effec-tively stops the operation of the clock signal generating means until the Bus access routine has been accomplished.  The clock signal generating means resumes operation when the access routine has been completed.
