Abstract: Abstract Articles to be galvanized, such as wire or chain link fencing, are passed in sequence through an acid bath, a water rinse, a flux bath, a molten zinc bath, and a water quench bath.  The quench bath becomes heavily contaminated with suspended, particulate zinc which renders the water unfit for discharge to a sewer or for passage through cooling tower for recycling. Zinc contamination in the zinc quench water is reduced by centrifuging the water. the treated water is cooled for recycling to the quench bath. When a molten lead bath followed by a water quench bath is used to anneal articles such as wire strand before they are qalvanized, lead contamination in the lead quench water is also reduced by centrifuging the water. The zinc and lead removed from the quench water streams are recovered and recycled.

Abstract: ABSTRACT OF THE DISCLOSURE    Apparatus for burning the gaseous and carbon particulate products from a kiln in which carbon is being calcined, including a pair of vertical cylindrical vessels, to which the effluent products of calcining are carried, by means of an input conduit, which enters the first vessel in a tangential manner near the bottom end, so that the gases will circulate circumferentially in a spinning flow inside of the vessel, as they progress upwardly to an outlet near the top of the first vessel, which leaves tangentially, and passes to the second vessel and enters it tangentially.  The gases then circulate around the inner wall of the second vessel spin flowing downwardly, where they leave near the bottom to enter the stack.  Means are provided on the entrance conduit for injecting combustion air into the inlet conduit prior to entry of the effluent products into the first vessel. Water may be included with the combustion air, if desired, which is sprayed into the combustion air, and mixes with the effluent products causing immediate combustion of the combustible gases, and of the carbon particles.

Granted: 1982-05-18
Abstract: Powers 3 METHOD OF MAKING DRY OPTICAL WAVEGUIDES                   Abstract of the Disclosure A method of making low loss glass optical waveguides, wherein at least one coating of glass soot is deposited by the flame hydrolysis process of a starting member.  The starting member is removed from the soot preform leaving an aperture therein.  While the preform is heated to i s con-solidation temperature, an atmosphere including a drying agent is caused to flow into the aperture and through the porous preform, thereby removing water from the preform while the soot is consolidated to form a dense glass article. The atmosphere contains optimal amounts of oxygen and drying agent to minimize leaching of dopant oxide from the preform. Since some of the dopant oxide is leached from the preform near the aperture, the central portion of the preform is initially provided with an excess amount of dopant oxide. The resultant draw blank is drawn into an optical waveguide filament.

Abstract: Abstract of the Disclosure Disclosure is made of a thermal-mining method of oil production, according to which a plurality of underground workings are provided as well as at least one injection gal-lery and one production gallery. Injection wells are driven from the injection gallery and production wells from the production gallery. Then, the heat carrier is force-fed to the oil-bearing bed via injection wells for heating the oil--bearing bed to a temperature at which oil assumes the requ-ired fluidity in the bed, and for forcing oil from the oil--bearing bed to the production wells. Prior to feeding the heat carrier into the bed, the injection gallery is filled with an insulating medium serving to preclude the breakthro-ugh of heat carrier to the gallery from the bed. After that, oil from the production wells is withdrawn to the production gallery from which it is supplied to the surface via injec-tion workings.

Abstract: Abstract of the Disclosure Parameters for optimum operation of a pulsed multi-section electro-static precipitator are disclosed.  It has been discovered that superior particulate collection can be achieved by a combination of pulse and con-ventional DC voltages.  The pulse rise time and decay time are made short enough so that adverse sparking conditions do not develop.  The base voltage (conventional DC voltage) is adjusted in coordination with the superposed pulse characteristics (pulse voltage, pulse frequency and pulse shape) to maintain an average current through the collected dust layer just below or at that value which would cause electrical breakdown of the dust layer. Base voltage may actually be below normal corona starting voltage in some cases.  The pulse produces instantaneously very high ion densities and electric field strengths.  In one design of precipitator, alternate sections are pulsed, with the other alternate sections functioning as collecting sections and merely having DC base voltage applied thereto.  In other designs, all sections including the collecting sections, may be pulsed to provide sufficient current to hold the collected particles on the collecting surfaces and to prevent reentrainment.  In some designs, at least one of the sections may be a transmission line which is pulsed.

Abstract: ABSTRACT     A method and apparatus for testing an elas-tomeric torsional vibration damper by oscillating the hub thereof on a shaker table to thereby simulate actual conditions of use.  Prior testing methods and apparatus have not compensated for changes in the mechanical properties of the elastomer which often occur during testing.  Such changes are usually due to build-up of heat within the elastomer.  According to the practice of this invention, changes in the mechanical properties of the elastomer are compensated for by continuously monitoring the phase difference between the hub and the inertia ring.  If the phase difference varies from a predetermined amount, the hub input frequency is then varied in such a manner as to maintain the predetermined phase difference between the hub and inertia ring.  In this manner a predetermined phase difference may be maintained throughout the test.

Abstract: ABSTRACT OF THE DISCLOSURE            Arrangement in data transmission between a transmitting computer, sending signal words containing start-stop information, message words and address-control signal information, and a receiving computer, for providing separate supervision of faults on the transmission lines and of such errors which are caused by faults in the signal equipment pertaining to the computer of the transmitter side, intermediate stations or the computer on the receiver side. The arrangement comprises means for generating and checking two check sums which are mutually supplementary, an inner check sum (S) for monitoring the hardware incorporated in computers and intermediate stations on a transmission path, and an outer check sum (YS) for monitoring the transmission lines. A check sum generating circuit is associated with the transmitting computer, and contains an adding circuit and a register which, by adding all the message words in a complete signal word, generates the inner check sum (S). An outer check sum generating circuit generates the outer check sum (YS) by adding the address control signal information, message words and the inner check sum. The correctness of the respective signal sum is checked in possible intermediate stations by reestablishing the sums in adding circuits and by comparison in comparator circuits between the respective reestablished sum and the corresponding check sum coming from the line. In the intermediate station there is furthermore generated, with the aid of an adder and a register, a new outer check sum on the basis of changed address-control signal information. The correctness of the respective check sum is also checked in the receiving computer by reestablishing the sums in adding circuits and by comparison in comparator circuits between the respective reestablished sum and the corresponding check sum coming from the line. In every terminal where the sums are checked and compared there is the possibility of trans-mitting control signals in response to the comparison results, which signals initiate retransmission of the message or switching to another line.
