Abstract: P 49 4677 IMPROVED HEAT RECOVERY FROM WET WOOD WASTE ABSTRACT OF THE DISCLOSURE Overall heat recovery from wet wood waste, particularly sawmill-generated hog fuel, is improved by a process for predrying the fuel. A wet oversize fraction of the fuel is combusted in a fluid bed reactor providing heat for drying the remaining smaller sized fraction of the waste pile to about 10-30% moisture by weight. The gaseous products of the fluid bed burning are contacted with the fuel fraction in, preferably, a rotary dryer. The dried fuel is then screened into coarse and fine fractions. The coarse fraction is fed onto a grate of a wood waste boiler. The fines fraction is injected into the boiler combustion in an air suspension. The amount of fuel fed to the fluid bed reactor is 10-25% of the total fuel flow, depending upon the moisture content of the fuel. The gases fed to the rotary dryer are less than about 1,200°F, to minimize "blue haze," by combining with minimum outside air.

Abstract: ABSTRACT OF THE DISCLOSURE    A double action revolver has a frame on which is mounted a cylinder, a trigger and a hammer  A hammer or main spring is interposed between the trigger and hammer such that pulling the trigger causes the string to compress and bias the hammer toward its fired position.  The position of the hammer remains essentially unchanged during initial trigger pull by virtue of a toggle spring device interposed between the frame and the hammer.  When the hammer spring is sufficiently compressed, a surface on the trigger contacts and engenders a deflection or buckling of the toggle spring device.  Buckling of the toggle spring device permits the hammer spring to drive the hammer to the fired position in which a cartridge is fired.     A spring loaded cylinder stop, having a projection adapted to be received in a looking recess on the cylinder, is adapted to be displaced forwardly, against the bias of its spring load during initial trigger return from the pulled position to its normal or released position.  Each locking recess is constituted by a primary; locking notch and secondary locking notch.   The primary and secondary notches are so arranged that forward movement of the cylinder stop causes it to leave the primary notch and enter the secondary notch.  This permits the cylinder to be rotated a few degrees under the impetus of a cylinder spring.  Further trigger return permits the cylinder stop to move rearwardly out of the secondary notch and over the surface of the cylinder.  when the cylinder stop clears the secondary notch, the cylinder automatically rotates to the next index position where the cylinder stop enters the succeeding primary locking notch and terminates cylinder rotation .

Abstract: Abstract of Disclosure This invention relates to environmentally sound hydrometallurg-ical methods and processes for extraction of cobalt, nickel and silver from complex concentrates.  The finely ground minerals are converted during two-stage oxidative caustic leaching at elevated pressures and temperatures to insoluble metal hydroxides and are separated from soluble sodium arsenate and sodium sulphate.   Cobalt and nickel are extracted from the caustic cake during a two-stage sul-phuric acid leach.   Solution purification for cobalt and nickel recovery proceeds on the basis that only one waste residue and one liquid  effluent  are  generated which meet  strict  environmental standards.   A small amount of cyanidation residue is generated after silver extraction by cyanidation from the acid leach resi-due.  Metal values extraction reaches +99.0%.  Arsenic and sulphur can be recovered in an innovative recycle system as sodium, zinc or copper arsenate chemicals and as anhydrous sodium sulphate.

Abstract: ABSTRACT OF THE DISCLOSURE Tarry residues often are formed in carbonylation reac-tions, such as those in which esters or ethers are carbonylated to produce ethylidene diacetate or carboxylic acid anhydrides, such as acetic anhydride   Such residues contain Group VIII noble metal catalysts, typically rhodium, which must be separated before the residues can be disposed of.   In the process of the invention, the residues are extracted with solvents which preferentially dissolve the tars.   Preferred solvents include alkanes, cycloalkanes, halogenated alkanes, and aromatic hydrocarbons, particularly cyclohexane, car?? tetrachloride, and toluene   Separation of the residues from the noble metal catalyst by solvent extraction makes possible the disposal of the residues and the return of the noble metals to the reaction for reuse.

Abstract: ABSTRACT OF THE DISCLOSURE.         A method of recovering a wide range of hydrochloric acid concentrations and high quality ferrous sulfate by-product in several hydrate forms from waste pickle liquor containing ferrous chloride. The waste pickle liquor is concentrated in a concentrator crystallizer by boiling off water and free hydrogen chloride until ferrous chloride precipitates as a crystalline hydrate.  Water and hydrogen chloride vapors from the concentrator crystallizer are directed to an acid vapor fractionator which produces an overhead line of substantially pure water that is condensed and discharged into a storage tank for subse-quent use.  Relatively weak hydrochloric acid from the bottom liquor in the fractionator is bled off and stored or mixed with stronger acid product formed at another stage of the process.  The hydrate crystals of ferrous chloride are fed to a reactor where sulfuric acid is added to react with the ferrous chloride crystals thereby forming hydrogen chloride and ferrous sulfate monohydrate.  Water and hydrogen chloride vapors from the reactor are discharged and condensed for producing the strong acid product.  When the strong acid from the reactor is mixed with the fractionator bottoms  the resulting mixture is controll-ed to yield any one of several desired concentrations.  A high quality ferrous sulfate by-product is produced as a result of at least two crystallizations occurring in the concentrator crystallizer and reactor respectively.  Even higher hydrates of ferrous sulfate may be produced by recrystallizing the ferrous sulfate monohydrate from the reactor thereby further improving the quality of the ferrous sulfate product.
