Abstract: A pattern information memory, provided with a font memory having a total bit capacity of n.A and comprising a number A of circulating memories each having a rewritable n-bit capacity, each bit being capable of storing one dot obtained by dot decomposition from each unit pattern. A minimum unit of designated addresses in the font memory is switched in accordance with a value of a number m (m = 1, 2, 3, . . . less than the number A) to provide a memory capacity of (n.sup.. A)/(n.sup.. m) patterns in combination of a number m of said circulating memories per each pattern of n.sup.. m dots. Writing and reading-out are performed by making once access to a number m of said circulating memories within a unit access time for one bit in a case : m=1. Accordingly, the writing and the reading-out for each pattern information are performed in a constant period of time irrespective of the value of the number m.

Abstract: A unit for interconnecting otherwise independently operable data processing systems. When one data processing system addresses the interconnecting unit, the unit acts like a peripheral device. It converts the address to a physical memory address for the other data processing system. Furthermore it interrupts the other system to effect a data transfer either to or from the other system.

Abstract: An automatic text processing system, wherein a text is printed by a typewriter and simultaneously recorded line by line in corresponding blocks of a magnetic tape. The system automatically prints the address of the block in which each line is stored, whereby an operator can cause the system to print selected lines of the text by posting the corresponding addresses on the typewriter. The lines or paragraphs of a text can be cancelled or added and their succession can be changed, by posting the addresses of the lines which are to be cancelled, added or shifted in the text. The fair copy is then automatically printed with the lines justified according to a format selected by the operator. According to another embodiment the system can be used to automatically search the information recorded on the magnetic tape.

Abstract: A program-controlled microprocessor of the microprogramming type adapted to be incorporated in a system including external circuit devices. The microprocessor is provided with an interface arrangement for connecting the microprocessor to the external circuit device wherein the interface arrangement includes data buses which are an extension of at least a portion of the data buses of the arithmetic section in the microprocessor. The interface arrangement also includes a control bus arrangement adapted to provide outputs relating to the contents in a read-only-memory register for microprogramming and an address bus arrangement which is adapted, when the external circuit device receives a microprocessing instruction through the control bus arrangement, to provide the external circuit device connected thereto with means for designating an address of the next micro-programming instruction to be executed.

Abstract: A high volume mailing installation is disclosed in which the output of a programmable high speed electronic digital computer provides destination and postage amount information, a high speed chain printer driven by the computer prints the destination information on address labels, and an authorized postage printing meter is mounted piggy-back fashion on the chain printer and responds to the same computer for automatic printing of authorized postage impressions of the calculated amount on the same mailing labels. The meter includes a fast, rugged solenoid-actuated segmented flat bed postage printer unit and fixed-program electronic digital postal accounting circuitry, with appropriate security features to prevent or detect postal fraud.

Abstract: A system for mechanically reproducing language characters in a cursive form in accordance with the natural style calligraphy of the language. Written letters are characterized by "links" with preceding and following characters, and mathematical rules describe the cursive script in terms of the form each letter takes dependent upon the preceding and following characters. The system includes input means for inserting characters, one at a time, and for providing coded representations of the characters. The coded representations are fed to decoder means which has as an output a selected combination of concatenation properties applicable to the character. Analyzer means analyzes variables dependent on the concatentation properties of a successive string of characters which comprise a character under consideration, a preceding character and a following character.

Abstract: Increasing the through-put rate of data processing in an electronic printer by accepting incoming data at a rate which varies inversely with the variable print density of the incoming data being received. The processing of non-printable or non-graphic characters, such as SPACE, associated with the performance of control functions is carried on at a higher rate than is the case for printable or graphic characters.

Abstract: The potential errors introduced by contact bounce are eliminated by a system which accepts applied key data. The system will accept key data provided first, that it is a proper logic code; second, that the system is in a state to accept new data; and, finally, that it is either different than the previous acceptable logic code or that it is preceded by a no key period measurably exceeding the contact bounce time and shorter than the normal human response time of the typist.

Abstract: A terminal device is disclosed which includes a typewriter and a keyboard in which the actuation of each key generates a signal in a first code which signal is temporarily stored. Also included is a code converter which translates the signal into a second code suitable for actuating the typewriter so as to print a character, corresponding to each actuated key, in a first location. Provision is also made for typewriting a message from a remote computer in a second location.

Abstract: A method for the application of data to a workpiece wherein the determination of the data occurs at a testing machine, and the data is transmitted to a marking device and applied by such marking device to the workpiece. According to the invention for the application of the data to the workpiece the workpiece is removed from the testing location of the testing machine and mounted at the marking device and the determined data remains stored after removal of the workpiece from the testing machine. The apparatus for the performance of the aforesaid method aspects is manifested by the features that the marking device is arranged externally of the testing location of the testing machine and a storage stores the data which has been determined at the testing machine.
