Abstract: PRODUCTION OF SYNTHESIS GAS AND RECOVERY OF PARTICULATE CARBON       (D#74,231-FB) ABSTRACT OF THE INVENTION        This is a process for producing gaseous mixtures comprising H2 and CO which includes the recovery of particulate carbon from the effluent gas stream from a partial oxidation gas generator.  Included in the process are the steps of scrubbing the effluent gas with water in a scrubbing zone to form a carbon-water dispersion, and mixing said dispersion in mixing and separating zones with a liquid organic extractant selected from the group consisting of a mixture of liquid organic by-products from oxo or oxyl process, a light liquid hydrocarbon fuel, and mixtures thereof.  The aforesaid liquid organic extractant may be obtained subsequently in the process from a thin centrifuge stream of carbon-extractant dispersion, or from a light liquid fraction from a distillation zone, or preferably from both sources. Make-up fresh extractant from an external source may also be introduced into the system.  In the separating zone, a clarified water layer and a carbon-extractant dispersion is produced.  Then follows the steps of: separating and recycling said clarified water to said scrubbing zone; separating said carbon-extractant dispersion and introducing same into a centrifugal separation zone; separately withdrawing from said centrifugal separation zone a thick stream of carbon-extractant dispersion and a separate thin stream of carbon-extractant dispersion; degasifying and introduceing said thin centrifugal stream into said mixing and separating zone as a portion of said liquid extractant, introducing said thick stream of carbon-extractant dispersion in admixture with fresh heavy liquid hydrocarbon fuel e.g. heavy fuel oil into a fractional distillation zone; recycling a light liquid fraction from said distillation zone to said mixing zone as a portion of said liquid organic extractant, and introducing a pumpable bottoms slurry of carbon heavy liquid hydrocarbon fuel from said distillation zone into said synthesis gas generator as at least a portion of the fuel.

Abstract: Abstract of Disclosure Circuits are disclosed for processing color encoded video signals, encoded pcr a format whcroln a chrominance signal in the form of a modulated subcarrier is buried in spectrum "troughs" in the midband of a wider band luminance signal, an illustrative use of the encoding format being in video disc recording.  The processing circuits serve, in use with composito signals developed during video disc play-back, to convert an input composite signal of buried sub-carrier format to an output composite signal of NTSC format. Carrier waves are amplitude modulated in accordance with composite signals developed during video disc playback, and applied to the input of a 1H delay line.  Subtractive combination of the modulated carrier waves from both input and output of the delay line effects a first comb filtering action to develop a chrominance signal output in the highband location desired for output use.  The delay line output is applied to an amplitude detector.  The detected signal is additively combined with the input composite signal to effect a second comb filtering action, developing a luminance signal output free of chrominance components and also lacking vertical detail components.  A phase inverted version of the detected signal is also additively combined with the input composite signal to effect a third comb filtering action, and the sum is low pass filtered to provide a vertical detail signal.  Combining of the products of the three comb filters provides the output composite signal.  The output of the amplitude detector is also used as a substitution signal input to the carrier wave modulator under defect pickup conditions.

Abstract: Abstract of the Disclosure A read only memory (ROM) patching arrangement is disclosed for providing valid output information when-ever ROM word locations containing invalid information are addressed.  The disclosed arrangement uses a plurality of small capacity PROMs as a decoder to detect the receipt of each address word representing a defective ROM location.          Upon each detection of a defective address, the decoder temporarily inhibits the output of the ROM and causes a small auxiliary memory to output valid program information as a substitute for that in the defective ROM location.          A counter is used as a supplemental addressing source for both the decoder and the auxiliary memory.  This increases the patching capability by subdividing the decoder and the auxiliary memory into 2n segments where n is the number of bits supplied by the counter.

Abstract: ABSTRACT      A process is described for the removal from copperplating baths of undesirable by-products which impair further copper-plating.  This process involves continuously distilling off from at least part of the copperplating bath sufficient water so that the solubility limits of the undesirable by-products are exceeded.  The by-products are precipitated and collected at the bottom of the tank thus permitting the separate removal of residual solution and precipitated by-products. This process is considerably more economical than previously known expensive regeneration processes.

Abstract: ABOVEGROUND SLIDING SUPPORT ASSEMBLY FOR A PIPELINE             ABSTRACT         The support assembly is constructed so that an aboveground pipeline resting thereon can move longitudinally and laterally relative to the path of the pipeline to allow for normal thermal contraction and expansion in the pipeline.  The support assembly is also designed for earthquake contingencies to prevent damage to the pipeline and to the support assembly upon occurrence of relative movement between the pipeline and the support assembly that is greater than that encountered with normal thermally moti-vated movement.  The support assembly includes a pair of vertical support members spaced transversely at a given location along the path of the pipeline, which vertical support members are interconnected by a transversely oriented cross member.  The cross member is adjustable relative to the vertical support members to orient it horizontally and is further adjustable to accommodate tolerance variations that occur during the fabrication and construc-tion of the components of the assembly.  A sliding shoe rides on the horizontal upper surface of the cross beam.  The shoe has two pairs of stanchions pivotally connected respectively to two clamps that wrap about the pipeline.  The pipeline is thermally and electrically isolated from the shoe, and thus the entire support assembly, by an insulating sleeve interposed in the pivotal connections between the stanchions and the pipe clamps.  The stanchions have provision for adjusting the height of the pivotal connection relative to the base of the shoe so that the pipeline can be elevated or lowered relative to the cross member, primarily to compensate for variances in the nominal pipeline elevation.  An energy absorbing bumper can be attached to one or more of the vertical support members at an elevation level with that of the pipeline to prevent substantial damage to the vertical support members and the pipeline upon occurrence of large relative movements between the two.

Abstract: PROCESS OF MAKING PULP FROM LIGNO-CELLULOSE CONTAINING MATERIAL            ABSTRACT OF THE DISCLOSURE     Method of making high yield pulp for papermaking with re-duced energy consumption, in which the pulp material, such as wood chips and other lignocellulose-containing material, is first heat-ed in an environment of steam to a temperature exceeding 120°C and preferably higher than 140°C, under corresponding steam pres-sure, and then subjected to a first fiber separation step in a disc type defibrating apparatus under maintenance of substantially the same temperature and steam pressure. The thus defibrated pulp material is passed through an electron radiation apparatus under reduced pressure, where the initially separated fibers are sub-jected to irradiation with electrons to enhance the pulping pro-perties of the pulp material.  Thereafter, the irradiated and in-itially defibrated pulp material is subjected to a second fiber separation step in a second defibrator, under lower temperature and pressure than in the first defibrating step, before it is dis-charged for further elective processing.  The irradiation of the initially separated fibers should be in an amount sufficient to carry out the two defibrating steps at an energy consumption of less than 500 KWh per ton of pulp, and preferably between 100 KWh and 300 KWh.
