Abstract: Abstract A carrier recovery apparatus for phase modulated carrier waves is disclosed.  A voltage controlled oscillator provides a variable frequency signal in response to a control signal and a first phase comparator provides a comparison output between an input modulated carrier and the variable frequency signal.  A loop filter supplies the voltage controlled oscillator via a frequency multiplier with the low frequency component of the output of the first phase comparator, the low frequency component serving as the control signal.  A clock recovery circuit generates a clock signal in response to the modulated carrier.  A second phase comparator provides a comparison output representative of the phase difference between the output of the first phase comparator and the recovered clock signal.  The low frequency component of this comparison output is superimposed on the output of the first phase comparator or the loop filter.  The invention substantially eliminates false locks and provides a stable recovery function even under stringent band conditions.

SIMPSON        METHOD OF AND APPARATUS FOR HEAT PROCESSING                  PHOTOSENSITIVE MATERIAL                 ABSTRACT OF THE DISCLOSURE   In the method and apparatus disclosed herein, heat processing pulsing current is passed, on command, through the conductive backing of an exposed record sheet of heat-processable photosensitive material.  The sheet resistance is included as one arm of a bridge which contains a settable comparison resistance in another arm.          The cold sheet resistance is sensed and is used by a sample and hold arrangement to set the comparison resistance to a corresponding comparison value which represents the cold sheet resistance multiplied by a preselected percentage.  That percentage is one which is known to correspond to the desired processing temperature to which the sheet temperature is to be raised in order to effect the processing of the sheet.  The passage of the heat processing current is terminated when equality is detected between two signals which represent, respectively, the prevailing sheet and comparison resistances, that equality indicating that the prevailing sheet resistance has arrived at a final resistance which equals the cold sheet resistance times the preselected percentage, and which therefore corresponds to the desired processing temperature.

Abstract: 13485:RDS                COPPER LEACHING PROCESS Abstract of the Disclosure A technique is provided for leaching copper from copper ore in which the ore is crushed to a maximum particle size small enough to expose a major proportion of the copper minerals in the ore. Crushed ore is wetted with separate additions of water and concentrated sulfuric acid and agglomerated to form lumps with apparent diameters about the same as the maximum particle size of the ore.  The quantity of acid is 50 to 120% of the quantity needed to react stoichiometrically with all the copper in the ore. The agglomerated copper ore is aged to indurate the agglomerate lumps and solubilize copper.  A leach liquid containing a low concentration of sulfuric acid is percolated through such a layer of indurated lumps for producing a pregnant leach liquid from which copper is recovered.  Aqueous raffinate from copper recovery is recycled as leach liquid.  When copper is recovered by solvent extraction the quantity of acid in the leach liquid is about the same as the quantity added by solvent extraction.  When the copper is recovered by cementation the quantity of acid in the leach liquid is about 130% of the quantity needed to react stoichiometrically with copper remaining in the ore after subtracting the portion made water soluble by aging.  If desired, ferrous ion in the raffinate can be oxidized to ferric ion before percolating such raffinate through an ore layer for leaching sulfide minerals.

Abstract: ABSTRACT         Polyurethane prepolymers having free isocyanate groups are treated with polyfunctional isocyanate-blocking agents to cause branching prior to or simultaneously with the addition of a curing diol.  The composition containing the curing diol is molded in a conventional equipment at a conventional temperature, e.g., 100-120°C.  The resulting shaped article can be demolded in a fraction of the time required in the absence of the blocking agent.  The shaped article is then post-cured within a temperature range of about 25-150°C, during which time the curing diol, if present in sufficient amount, displaces the blocking agent and forms a cured, linear polyurethane.  A typical suitable blocking agent is a substantially uncrosslinked phenol/formaldehyde resin.  The curable composition can be prepared in one step from the diisocyanate, glycol, and blocking agent; and a composition containing all the components, including the curing diol, can be prepared in one or more steps.  If a nonbasic blocking agent is used in the presence of the curing diol, it is recommended to use a tertiary amine catalyst to selectively catalyze the blocking, rather than the curing, reaction.  The cured linear polyurethanes have good physical properties, comparable with those of the prior art polyurethane elastomers.  Partly crosslinked cured polyurethanes find utility where resistance to organic liquids is important.
