Abstract: A report generation control system for operating a text processor to produce output reports containing inter-report summary data from data processing-type files. The system is compatible with text pagination functions and is useable by a text entry/revision operator with no programming skills. The system permits the operator to describe the desired report by keying an example page of the report in the exact desired format and then editing the example page by replacing the required variable file data examples with descriptive instructions and by inserting summary instructions. The system scans the edited example page for instructions, breaks it down into logical components and compiles the components into program routines which will produce the desired output report.

The related linguistic expressions in the vocabulary are concatenated and displayed for operator review.

Abstract: A process automatically generating topology data for fabricating large scale integrated circuits. Technology data, a logic function description and logic circuit components are generated and input to a data processing system together with geometric dimension data descriptive of the basic elements of the logic circuit components. The geometric dimension data is assembled into a plurality of intermediate level geometric topology patterns under control of the logic function description and the intermediate level geometric topology patterns are assembled into a prime level geometric topology representative of the logic function description. The logic circuit components are merged with the prime level geometric topology to produce a grid array to be fabricated into a large scale integrated circuit.

Abstract: A system for automatically adjusting text codes and control codes stored in a memory into text blocks having variable formatting parameters and variable line counts. The detection of a code signal causes the system to enter a non-playout adjust mode. The operator is then prompted to enter a line count for the text block to be formatted. After the line count is entered, the system proceeds to adjust in memory the number of lines of text equal to the line count to the predetermined formatting parameters with no external output of the text. An interrupt of the adjust mode occurs upon the detection of any one of a number of predefined special conditions including the end of text, mode-measure codes in memory, special codes (e.g. stop, edit, error, page end), hyphenation requests, forced line overflow, or upon completion of the text block line count.

Abstract: A system for reducing storage requirements and accessing times in a text processing machine for automatic spelling verification and hyphenation functions. The system includes a method for storing a word list file and accessing the word list file such that legal prefixes and suffixes are truncated and only the unique root element, or "stem", of a word is stored. A set of unique rules is provided for prefix/suffix removal during compilation of the word list file and subsequent accessing of the word list file. Spelling verification is accomplished by applying the rules to the words whose spelling is to be verified and application of the said rules provides, under most circumstances, a natural hyphenation break point at the prefix-stem and stem-suffix junctions.

Abstract: A system for reducing the computation required to match a misspelled word against various candidates from a dictionary to find one or more words that represent the best match to the misspelled word. The major facility offered is the ability to computationally discern the degree of apparent match that exists between words that do not perfectly match a given target word without requiring the computationally tedious procedure of character by character positional matching which necessitates shifting and realignment to accommodate for differences between the candidate and target words due to character differences or added and dropped syllables.

Abstract: Apparatus for rotating a cathode ray tube (CRT) which is operated as a graphic display through 90 degrees such that different size pages of data may be displayed while minimizing the control circuitry required. The display deflection yoke is fixedly attached to a support frame for the display. The CRT is rotatably mounted within the yoke and held by annular thrust bearing which allows the CRT to be rotated 90 degrees. A switch is actuated by the rotation of the CRT to select between sets of control resistors to control the raster scan of the CRT in accordance with its orientation.

The apparatus includes at least one rotatable cylindrical member having tapered slots disposed therein 180 degrees apart for receiving the leading edge of the sheet to be flipped, and a clamping member which permits the slots to remain open during the sheet insertion, clamp the sheet during rotation of the cylindrical member, and again permits the slots to open at the release point such that the flipped sheet may be released. The location and angle of the slots in the cylindrical member are such the initial force for rotating the cylindrical member is imparted thereto by the entry of document sheet into the slot.

Abstract: Disclosed is a method and apparatus for establishing, verifying, and correcting tab settings and indexing parameters for text to be printed by a word processing system. The apparatus includes logic and related control networks for establishing a line of codes in memory indicative of the location and status of such tab settings and indexing parameters, for setting an electronic tab rack, for verifying and correcting such settings and parameters by, and responsive to, the advancement and backspacing of the printer carrier, and for producing a hard copy printout, during entry and playback, of such tab setting and indexing mode status.

Abstract: The aesthetic characteristics of adjacent characters are used to enhance the quality of output in a proportional spacing printer and to provide right margin justification for composing. Spacing between characters is determined on the basis of the character being printed and the preceding character already printed on the page. An intercharacter displacement memory contains a list of ideal spacing for all combinations of characters to be printed. As each character is typed, it and the previously stored preceding character address the intercharacter displacement memory. The output of the intercharacter displacement memory is the ideal value of escapement for this combination of characters and font style. The printer positions the print head prior to printing the next character, rather than positioning the print head after the previous character is printed.

Abstract: A method and apparatus associated with word processing equipment for producing a preliminary printout of accessible lines of intermixed text characters and code characters representative of the format of such text. The apparatus includes logic controlled gates for selectively gating text codes, instruction codes, and reference line number codes to a print control coupled to, and controlling the printing by, a printer. Specific networks enable the printing of "font change" instructions and identifications and characteristic identifier symbols indicative of the presence of an instruction code. Audit print codes representing material ones of the instruction codes are substituted for the usual printer functional response to those instruction codes, that is, a code representation of the instruction code is printed instead of the printer executing the instruction.

Abstract: A control system for randomly accessing the contents of a recirculating shift register memory under the control of a processor. The processor provides to the control system an address equivalent to the number of positions the operating point (defined by an operating flag) is to be moved in the shift register memory to access the information desired by the processor. The control system decodes the address, removes the operating flag from the memory character stream and reinserts the operating flag in the memory at the point desired by the processor during a single revolution of the memory.

Abstract: Spelling errors in a word processing system are detected and presented to the operator for correction at the end of a document page. A dictionary memory contains representations of the correct spellings for words most frequently used. As each word is typed, it is stored in a word queue where it is compared to the contents of the dictionary memory. If the compare is unequal, then the word and its location on the page are stored in an error memory. When an end of page indicator is set the printer automatically repositions the print head at the ending character of the first word in the error list. When the operator keys in the correct spelling, the printer is caused to remove the misspelled word from the page and type the correct spelling. The corresponding word in the error memory is also corrected. As each misspelled word in the error memory is corrected, the remainder of the memory is scanned and repetitions of the same spelling error are automatically corrected.

Abstract: A memory control structure for a pipe-lined mini-processor which allows the processor to work with relatively slow memories without degradation of performance. The memory structure includes a memory selector which provides an interface between the processor output and the inputs of a plurality of memories of different types and speeds. The memory selector receives address and control information from the processor and generates the timing and selection signals for the memories. The memory structure also includes fan-in circuitry connected to the outputs of all the memories. The fan-in circuitry includes latches for sampling the output of each memory and multiplexing the memory outputs onto a single data bus for transfer of data from the memories to the processor.

Abstract: Improved hyphenation apparatus is combined with word verification apparatus to automatically provide hyphenation points for input words from a keyboard or other input device. The spelling of each word input to the system is verified by the digital reference matrix section of the apparatus by calculating a vector magnitude and angle for the word which is compared to the contents of a storage dictionary of words. Each cell of storage in the storage dictionary, in addition to containing a unique angle representation of the input word, contains a byte of data representing the valid hyphenation points for the input word. When an input word is verified to be correctly spelled, the hyphenation byte is read out of dictionary and used by the hyphenation section to reassemble the word in hyphenated form. The hyphenated word is then displayed to the operator for appropriate action.

A plurality of unidirectional busses are provided to interface the processor and memory and a bidirectional buss is provided to interface with the input/output devices. The logic circuitry provides a control function to steer data over the proper buss structures interconnecting the processor, the memory and the input/output devices and provides those interconnections in a manner which allows the processor to overlap input and output functions.

Abstract: Apparatus for automatic hyphenation of input words from a word processing system. The apparatus includes a digital reference matrix memory containing a vector representation of all legal hyphenations for each dictionary word in the form of a calculated magnitude and associated unique vector angles. The vector magnitude constitutes the address data for accessing the memory. When an input word is received for hyphenation, a hyphen is added to the word and its magnitude is calculated. The memory is accessed for an address which equals the calculated magnitude. If the address is not found, a signal is generated indicating that the word cannot be legally hyphenated. If the address is found, then the corresponding angles, representing legal hyphenations of the input word, are compared with test words generated by sequentially inserting hyphens in the input word. All equal compares are flagged and the corresponding hyphenated input words are gated onto the output line.

Abstract: A digital reference matrix apparatus is disclosed for verifying input alpha words from a keyboard, character recognition machine, or voice analyzer as valid linguistic expressions. The organization of the digital reference matrix is based upon the character transfer function of the input apparatus. The digital reference matrix contains a vector representation for each dictionary word in the form of a calculated vector magnitude and unique vector angle. The set of magnitudes and angles is stored in the digital reference matrix using a form of run length coding by storing a single magnitude pointer followed by the chain of unique angles for words having the same magnitude. The vector magnitude so calculated constitutes the address data for accessing the digital reference matrix.
