Abstract: ABSTRACT OF THE DISCLOSURE:        A data processing system is disclosed for selecting the correct form of a garbled input word misread by an optical character reader so as to change the number of characters in the word by character splitting or concatenation.  Dictionary words are stored in the system, having characters which are flagged for segmentation or concatenation OCR misread propen-sity.  The OCR word and a dictionary word are loaded into a pair of associated shift registers, aligning their letters on one end. The dictionary word characters are inspected  for error propensity flags.  When a splitting propensity, for example, is found for a character, special conditional pro-bability values are accessed from a storage and a calculation is performed of the probability that the first character of the dictionary word was split by the OCR into the first and second characters of the OCR word   This regional context probability is compared with the probability of a simple substitution error for the characters.  If the probability of segmentation is larger, the OCR characters in the first shift register are shifted one space with respect to the dictionary word characters in the second shift register so that subsequent character pairs to be compared are properly matched.  The greater calculated probability is combined in a running product.  The dictionary word with the largest running product is output by the system as the most likely correct form of the garbled OCR input word.           In addition to optical character recognition, the system disclosed may be applied to correcting segmentation errors in ph?n?m?-characters output from a speech analyzer.

Abstract: ABSTRACT A vertically fired means for the combustion of waste gases in a noise-proof manner having a vertically oriented cylindrical furnace with burner insertion into the bottom of the furnace which s raised a selected distance above the surface grade.  The inlet air opening at the bottom of the furnace is of a cross section area of the combustion zone.  A cylindrical windshield encircling the bottom of the furnace provides limited access of air to the area below the inlet air opening at the bottom of the furnace to suitably isolate wind flow from the inlet air opening.  The cross-sectional area for air flow due to limited access is at least equal to a selected fractional area of the furnace, which is the inlet air opening.  Suitable isolation of air flow energies from the inlet air opening requires the limit-ed access area to be no greater than 2.5 times the air inlet area.  The inlet air opening is preferably not more than 85% of the furnace area.  One or more burners are provided from suitable manifolds so that the flame resulting from the combustion of the waste gases issues preferably in the inlet air opening to the furnace.  The inlet air opening area is preferably in the range of 0.2 to 0.85 of the cross section area of the furnace.

Abstract: Abstract of the Disclosure A frequency selector comprising a first control member for frequency preselection changing and a second control member for changing the preselec-tion frequency.  The first control member can be pushed manually to position successive screws, each representing a preselection frequency, at a particu-lar location in which the screw by abutment with a feeler rod sets a tuning member at the preselection frequency.  Each screw carries an extremely toothed nut which at the predetermined location can engage with a toothed wheel carried on the second control member.  Rotation of the second control member causes rotation of the nut and advancement or retraction of the screw to adjust the fine tuning.  A catcher member associated with the first control member engages the toothed wheel whenever the first control member is oper-ated and moves the toothed wheel away from the particular location to a second location at which the toothed wheel remains.  Thus, rotation of the second control, member has no effect on tuning until the toothed wheel is returned to the particular location and this may be done by pulling on the second control member.  The dual action required prevents unintentional changing of the preselection frequency.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to the use of methyl formate as an adjuvant in the formation of phenolic foam.  The addition of methyl formate to phenol-aldehyde resoles caused a substantial reduction in resole vis-cosity and thus allows for the processing of resoles which are otherwise too viscous to be foamed.  A further advantage of methyl formate as an adjuvant in the form-ation of phenolic foam is that it also functions as a blowing agent.  In its use as a blowing agent, methyl formate is employed in combination with 1,1,2-trichloro-1,2,2-trifluoroethane.  Depending upon the nature of the phenolic foaming resin, the use of methyl formate in combination with 1,1,2-trichloro-1,2,2-trifluoroethane as the source of blowing action further provides the advantageous result of allowing for the formation of a       phenolic foam of reduced friability.

Abstract: METHOD AND APPARATUS FOR PRINTING INDICIA          ON A CONTINUOUS, ELONGATE, FLEXIBLE THREE-DIMENSIONAL MEMBER                 Abstract of the Disclosure Electrical wires and other continuous, elongate, flexible members having a three-dimensional exterior printing surface are marked with alpha-numeric characters by longitudinally feeding the wire past an electronically controlled ink jet printing head assembly that forms the characters by directing a positionable jet of ink onto the exterior surface of the wire.  A wire feed transport receives the electrical wire from a storage reel and longitudinally feeds it through aligned guides establishing a wire guide path.  The guide path carries the wire past a printing station at which the printing head assembly ejects a jet of electrostatically charged ink drops which are selectively deflected in a dimension transverse to the wire and in synchronism with the rate of longitudinal travel of the wire as established by the transport so that the ink drops impinge on the exterior three-dimensional wire surface in patterns which form the desired characters.  The printing head assembly and wire guide are adjustably mounted for achieving precise registration between the ink jet and wire surface.  Control means including a drive for the transport, a wire travel encoder, a printing head control unit, a data input terminal and an interface circuit cooperate to receive predetermined alpha-numeric indicia and to automatically operate the transport and ink jet printing head assembly to repetitively mark the wire with an identifying, multi-character code, wherein the code is repeated at selected, longitudinally spaced intervals along the wire.  After being marked, the wire is automatically coiled in a coiling pan disposed at the discharge end of the wire guide path.  The wire is severed at a predetermined length by an automatic cut-off device operated by the control means in response to wire length data received by the control system through the data input terminal along with the alpha-numeric identification code.
