    Evaluating the true worth of computers as applied to assembly machines is a valid quest. Assuming computers have a place in the world of assembly machines, several questions naturally arise and should be pondered: In what areas are they applicable and why?; What is the real worth of computers to assembly machine systems?; What are some of the major conclusions to remember in their application?

    Active and passive infrared nondestructive testing (IRNDT) techniques were investigated to determine their limitations and potential military applications. Active IRNDT methods involved the use of various techniques, in which radiation from a conventional infrared heat lamp and a CO2 laser were used to heat a specimen. In these methods, a scanning infrared radiometer and an infrared camera were us... View full abstract»

    The measurement of radiation (ultra-violet, visible, or infrared) from a surface as a means of knowing the surface temperature has been found useful in many applications. One of the simpler types of instruments which uses this principle is a brightness pyrometer. The brightness pyrometer relates radiation to temperature on the basis of radiation magnitude, which is a function of temperature, but t... View full abstract»

    The conventional method to professional growth has been to climb up a commercial ladder by mostly hard work. Individuals need to be able to change from one ladder to another thus making their own opportunities for professional growth. Hard working geographic areas like Los Angeles, Boston, Houston, and Cleveland, to name a few, have made it possible for technical people to change ladders with very... View full abstract»

    The serious student of Process Control must recognize that one important facet of his education is the development of the mathematical sophistication required for him to approach the subject creatively. The transform methods commonly used in the solution of a control problem convert the dynamic analytical structure (differential equation) used to describe all dynamic processes into static algebrai...

    Transistorized alternating current servomechanism design offers a number of advantages over other types because of their small size, low weight, high reliability, precision accuracy, and wide range of control. These lecture notes describe a cryogenic oxygen flow control servomechanism subsystem typical for an auxiliary power unit fuel system. Three possible types of feedback for this type of subsy...

    This paper deals with the problem of selecting controllers and control valves for some of the most common chemical process control systems. Because a dynamic analysis can seldom be justified for most control systems, it is important to have some general rules for controller and control valve selection. An attempt will be made to present such general recommendations for flow, level, pressure and te... View full abstract»

    The equations required for analyzing the performance of imperfectly coupled transformers in dc-to-dc conversion applications are described. Results are shown for both the untuned and the tuned primary cases. Given the output power requirements and a reasonable set of limitations on the transformer parameters, the optimum transformer parameters can be detennined. An example is given of the optimiza...

    The problem of estimating the state of a linear system over a finite time interval in the presence of noise is considered. The expected value of the integral of the quadratic error is taken as the performance index. A configuration of the same type as the Kaiman filter is assumed with the restriction that the gain must be constant. An integral equation is obtained as a necessary condition for the ...

    The supply of electrical power to small, remote situations is usually carried out by means of a two-wire, single-phase connection. Frequently, this remote situation is developed and the electrical power consumption increases significantly. Not only is there an increased overall demand on this service, but the provision of three-phase supplies to run electric motors also becomes highly desirable. T... View full abstract»

    Cited by:  Papers (2)
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (957 KB)  

    A new mathematical model for permanent-magnet stepping motors is proposed which takes into account the effect of the saliency of the poles. A comparison of the predictions based on this model is made with those based on the earlier models and the specifications of the manufacturers. The results show that the new model is much more accurate and more suitable for applications in computer control. View full abstract»

    The paper deals with the bidirectional speed control of a split-field dc series motor by commutating the two fields alternately to the supply using SCR switches. The whole system is simulated on an analog computer to investigate the effect of system parameters on its static and dynamic performances. Optimum values for the components of the control circuit are also suggested. View full abstract»

    It is well known that magnetic-coupled monostable multivibrators have isolated and high-power outputs. These multivibrators which have been presented so far employ the operation of the major hysteresis loop. In these multivibrators, however, the output pulsewidth cannot be controlled over wide ranges and is severely influenced by variations in the source voltage. These problems can be solved by us...
