    Publication Year: 1970, Page(s): 588
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (255 KB)

    IBM's manufacturing plants offer a valuable test ground for studying plant automation techniques. In looking for ways to improve production processes manufacturing engineers in the company's plants have experimented with many approaches to the structure and design of plantfloor computer systems. The structural solutions have ranged from dedicated stand-alone controllers scattered throughout a plan... View full abstract»

    This paper is divided into two main parts. The first is concerned with definitions of concepts and terms of importance to the architect of integrated manufacturing systems. It describes the operational environment, how the manufacturing systems are going to be used, and a variety of system requirements. Priorities are established and a set of guiding principles for system design are proposed. In t... View full abstract»

    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (647 KB)

    An integral part of a process control and testing system used in several IBM plants is the transmission control unit (TCU). This paper discusses the design of the TCU, which provides the communication link between as many as 512 satellite computers and a central computer. It uses a microprogrammed polling scheme to establish connection with the satellites that need service and it permits messages ... View full abstract»

  • PCOS: A Process Control Extension to Operating System/360

    Publication Year: 1970, Page(s):620 - 632
    Cited by:  Papers (2)  |  Patents (3)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1288 KB)

    This paper discusses the design and implementation of an extension to IBM Operating System/360 that is called PCOS and is intended specifically for use in “real-time” control of IBM manufacturing processes and testing. The most important part of PCOS is a Real-Time Control Program (RTCP) which is initiated at system start-up time as a “never-ending” task. The RTCP contr... View full abstract»

    Cited by:  Papers (2)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (826 KB)

    A data collection and analysis system has been developed to control magnetic tape head testing and provide data analysis for manufacturing process control. Data collection is achieved by a system of test terminals controlled by an IBM 1130 computer, which is a satellite of an IBM System/360 Model 50 computer. The data base made possible by this system provides a means of tracing recurring failures... View full abstract»

    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (951 KB)

    This paper reports the development of a computer-controlled machine for non-contact inspection of manufactured parts. The machine, called PAMM (Precision Automatic Measuring Machine), is capable of providing “on-the-fly” measurements accurate to within 100 microinches. The intersection of a rotating spiral slot with a stationary linear slot produces a moving aperture for scanning in ... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (895 KB)

    The recently announced IBM System/7 was developed for use in a broad range of data acquisition and control applications and provides the foundation for comprehensive plant automation applications. Its unique modular structure and broad spectrum of features satisfy the basic plant automation requirements described in the paper by Kinberg and Landeck in this issue. In the present paper the functiona... View full abstract»

    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (531 KB)

    A tandem connection of terminals for a data collection system has certain desirable advantages over the more common radial configuration. To make use of these advantages, high-speed transmission links are required. This paper describes the transmission capability necessary for a high-speed digital data repeater when it is restricted to an in-house environment. The transmission techniques discussed...

  • The Percus-Yevick Theory and the Equation of State of the 6:12 Fluid

    Publication Year: 1970, Page(s):668 - 676
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (727 KB)

    The Percus-Yevick theory can be used to calculate the pair distribution function and from this the equation of state. The conventional method is to calculate the pressure of compressibility directly, unfortunately yielding poor results for the 6:12 fluid at low temperatures. In this paper results are obtained using an indirect method, in which the energy is calculated from the pair distribution fu... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (336 KB)

    The iterated consensus method for obtaining prime implicants of Boolean functions has several advantages with respect to the conventional tabular method. However, when one attempts to apply the iterated consensus method to multiple-output functions using the rules set forth in the existing literature, it is possible that some of the prime implicants will not be produced. This communication present... View full abstract»

    Sets of waveforms called TPF's, which are products of trigonometric functions, may have application in communications technology, network analysis and signal processing. This communication briefly reviews the characteristics of TPF's and presents methods for calculating their cross-correlation coefficients when 1) all TPF's in a set have harmonic factors with the same set of values, and 2) the har...
