Abstract: ABSTRACT      Apparatus for circulating molten metal in a furnace comprises an electromagnet the coil of which is adapted for energisation from an alternating current source and the core of which is elongate and projects from both ends of the coil. The core is disposed so that 25% to 50%, preferably 37%, of its length is at one axial side of the mid-point of the coil, and the part of the core projecting at the said one axial side of the coil has a coating or casing of a refractory material.   The apparatus may be mounted with its core horizontal in a side wall of the furnace but it is preferred to dispose the core vertically with the heat shield close to the surface of the molten metal.   A duct member may surround said part of the core and may be shaped to direct the molten metal laterally.   A partition or other form of baffle may be disposed externally of the duct between the inlet and outlet of the duct to prevent the molten metal leaving the outlet of the duct from passing straight back to the inlet of the duct.

Abstract: ABSTRACT OF THE DISCLOSURE         A precision current source arrangement with a multiple current source which supplies a number of currents which are identical in a first approximation.  These currents are each individually applied to one of the input terminals of a coupling circuit which has an equal number of input and output terminals.  By means of a periodic control signal this coupling circuit realizes such a connection pattern between the input and output ter-minals in a cyclically permuting fashion, that each of the output terminals is coupled to each of the input terminals within a constant cycle time dur-ing identical time intervals.  By subjecting the currents which appear at these output terminals to a low-pass filter action a number of very accu-rately identical currents are obtained.

Abstract: Abstract of the Disclosure A digital signal generator that produces multi-frequency tones in the voice band range for use in telephone station sets utilizing multitone dialing.          Amplitude information decribing each of eight voice band frequencies is digitally encoded into a sequence of multi-bit words describing the amplitude at successive data points along the waveform.  The eight frequencies so encoded are separated into four upper and four lower frequencies and stored in two solid state read-only memories.  Upon command amplitude data words for one upper and one lower frequency are sequentially read out of the memory in time synchronization, added, and their sum applied to a digital delta modulation circuit.          The delta modulator determines the change between two successive data word sums and describes the change by an output of either a binary one or a binary zero.          The delta modulator output thus comprises a series of binary ones and/or zeros forming an aperiodic digital pulse train which is applied to an output module con-sisting of an integrating network to synthesize an approximation of a multitone dialing waveform which is compatible with the common carrier telephone network.

Abstract: ABSTRACT           A dense, uniformly layered, relatively unexpanded extrusion cooked vegetable protein based meat analogue product is provided, which has meat-like texture, mouth-feel and appear-ance characteristics permitting use of the product as a full substitute for meats such as pork, beef, fish and poultry.  In addition, a method and apparatus for making the products hereof is also provided.  The product is preferably made up of a mix-ture of a vegetable protein such as defatted soy flour and moisture which is extrusion processed to present an analogue having a plurality of juxtaposed, manually separable meat-like layers which are substantially untwisted relative to each other and strongly resemble real meat.  The processing method prefer-ably includes extruding a vegetable protein-water mixture in a first extrusion cooker under conditions to render the mixture hot and flowable but still substantially unoriented, whereupon the mixture is passed through a second extrusion cooker which is equipped with a hollow tubular spacer on the extrusion end thereof.  In this manner the mixture is subjected to further axial and transverse displacement forces in the second extruder barrel is order to adequately work and stretch the protein therein while being subjected primarily to axially directed displacement forces in the elongated die spacer for facilitat-ing the formation of a layered meat-like structure therein prior to extrusion; in addition, conditions of temperature and pressure are controlled so that the resultant product is rel-atively dense and unexpanded.  In other froms, the density, chewiness and other properties of the analogue products hereof can be selectively altered by the addition of coloring agents, pH modifiers or other ingredients, or by varying the process conditions.

Abstract: CHEMICAL RECOVERY UTILIZING EVAPORATION STEAM AND EXCHANGERS IN STEAM STRIPPING SYSTEM     ABSTRACT OF THE DISCLOSURE        A method of treating waste liquors such as those derived from the sulfite or Kraft pulp making process is disclosed which provides recovered by-products of high purity while moreover decreasing the total amount of process steam required. The method comprises steam stripping the evaporator condensate feed to remove volatile chemical by-products there-from, and thereafter directing the stripping steam for reuse in concentrating additional volumes of feed in the evaporator. In this manner, the only steam lost during the stripping opera-tion is that used for increasing the sensible heat of the evapo-rator condensate feed within the steam stripping column. The condensed steam and volatile by-products resulting from evapo-rator heating operation are then preferably directed to a fractionation column or columns in order to separate and re-cover the valuable by-products for reuse of sale. In situa-tions where the condensate feed contains volatile, nonconden-sible gases which are valuable for reuse, the evaporator con-densate feed may be preheated and contacted with evaportator vent gases. The latter are partially condensed to allow the noncondesible gases to be recovered and reused, and the con-densed liquor is cooled and passed through an activated carbon column prior to steam stripping in order to facilitate the re-covery of chemical by-products and enhance the purity thereof.

Abstract: LAYING OF SUBMARINE PIPES                     Jacques, Edouard LAMY     Abstract to the disclosure The invention relates to a method of laying submarine pipelines by submergence from the surface or from an adjacent level with one point of the pipeline being secured near to the surface so that the pipeline on being submerged comprises a section descending from this point towards the bed and connected by a curved section to the part of the pipeline already laid on the bed, in which weights are suspended from the pipeline at intervals thereon, at least at the time of its submergence, such that the assembly has a slightly negative buoyancy and the pipeline sinks slowly in the water until it is slowed down and stopped when the weights contact the bed, the weights thus acting as a guide rope.  The invention is applicable both to the case in which the sections of the pipeline are assembled on a floating device and the pipeline is lowered into the water as assembly proceeds while the floating device is moved along the laying course, and to the case in which the pipeline, previously constructed by the assembly of a certain number of sections, is towed along the laying course and is associated with floats which maintain the pipeline on the surface of the water or a short distance there-beneath and which can be put out of action to allow the pipeline to sink.

Abstract: COMBINED MULTIPLE SOLVENT AND THERMAL      HEAVY OIL RECOVERY METHOD          (D#73,910-F) ABSTRACT OF THE DISCLOSURE  Petroleum may be recovered from viscous petroleum-containing formations including tar sand deposits by a process involving injecting into the formation a multiple-component solvent for the petroleum and a thermal fluid.  At least one solvent component is gaseous at the temperature and pressure of the petroleum reservoir such as carbon dioxide, methane, ethane, propane, butane or pentane, and at least one component is liquid at the reservoir conditions, such as hexane and higher molecular weight aliphatic hydrocarbons or aromatic hydrocarbons such as benzene.  The multiple solvent injection is continued with no production until the pressure is from 50 to 250% above the vapor pressure of the solvent, at which pressure the solvent mixture is substan-tially all in the liquid phase.  Recovery of petroleum and solvent is from a remotely located well by reducing the pressure in the portion of the formation contacted by the solvents to a value from 5 to 100% above the vapor pressure of the gaseous solvent.  A fluid heated to a temperature above the boiling point of the solvent, such as steam, is then injected into the same well as was used for solvent injection.  The heated fluid raises the temperature of the solvent on contact therewith, causing vaporization of the gaseous component, which gaseous solvent expands to force viscous petroleum with liquid solvent dissolved therein toward the production well.  In formations having oil satura-tion greater than 50%, this oil saturation should first be reduced to a value below 50% to prevent plugging.     I
