In today's burgeoning electronics industry, quality control in the manufacturing process is of foremost concern. The application of vision technology to the inspection process as related to various stages of printed circuit fabrication is described. Application areas include bare board inspection, missing or misoriented components, and missing leads through the board. These are related to vision system performance requirements. Described is the design of an advanced vision processor and its application to turnkey printed circuit board inspection systems.

This paper presents a computer program called TUNES. TUNES is a very useful, friendly, software tool which substantially reduces the time required to design, implement, and maintain advancedcontrol strategies. TUNES does this by modeling dynamic processes with relatively simple models. What specifically is TUNES? Who can benefit using TUNES? Why is TUNES beneficial? How does the user work TUNES? There are the questions that the authors try to answer.

This conference proceedings contains 38 papers delivered at the advanced Composites conference. Main topics of this conference were developments of new advanced composite materials and their applications. Most of the papers present and discuss the results of the achievements in development of the plastics filament or fabric reinforced laminates. A few papers discuss the achievements in metallic matrix fiber reinforced composites. As a speciality the silicon carbide whiskers development and use as reinforcing fiber for metals' and ceramics' reinforcement is discussed. The use of computer aided engineering, design and processcontrol is also discussed. The automation of laminating, reaction injection molding and forming is also described, and the squeeze casting of fiber reinforced metals is described.

The IBM 1800 computer and associated 1070 multiplexors served Lima Refinery for more than 15 years. In 1982, an Applied automation Inc. OPTROL 7000 (Perkin-Elmer 3230) computer was installed for advancedcontrol applications. The OPTROL, combined with an existing Hewlett Packard 3000 administrative computer, provided a powerful yet economical MIS replacement alternative. The OPTROL performs both processcontrol and MIS data acquisition providing data base access for all real-time applications. Daily average information is passed from the OPTROL to the HP 3000 where it is combined with laboratory data and other management information to produce the various MIS reports. A new Aromatics Plant, constructed in 1984, was added to this network requiring both advanced computer control and MIS reporting.

This paper describes a new type of cooking analyzer. The basic idea behind the analyzer is to perform multiple measurements of inorganic and organic substances on a small process liquor sample. The measurements are carried out by means of a carrier flow principle in which the sample is handled and passed through measurement detectors in a constantcondition liquid flow. The method offers various advantages such as simple sample handling, optimal measuring conditions and independence of zero base-line drift. Optical and electric detectors produce a comprehensive view of the situation in the digester at any given moment. The results of mill trials at batch and Kamyr digester houses are referred to, and possible contributions to the improvement of control are discussed.

Computer-aided monitoring and control of distribution networks from control centres has been extensively employed since the early seventies. These systems optimize the data flow between control centres and individual substations. Extensions down to the station and feeder levels including protection function as well as advancedautomation schemes for the substation itself were rare. Only some pilot systems based partly on process computers and partly on micro-processors have been commissioned over the past decade. The availability of low-cost microprocessors with increased capability now allows the intelligence within the substation to be distributed both functionally and physically, thus forming a system consisting of autonomous units for individual functions, but connected together by serial data links for exchange of data. These autonomous units can also 'stand-alone' to replace existing equipment. This concept allows large scale production of the individual units, with unique software without sacrificing the benefits of an integrated system.

Examples of NDT automation research at Fokker are bond testing, ultrasonic C-scan and interference holography. With bond testing, the measuring process has been defined with a development system. Manually used correlation graphs have been transformed into polynoms suitable for computer calculation. Measuring procedures have been developed. Ultrasonic C-scan is suited for computerised data collection and image processing. Interference holography has been used as a method to detect mechanical deformations with the aid of coherent laser light. These deformations are created by thermally introduced stresses. The holographic fringe pattern is processed by image analysis techniques.

The Naval Undersea Warfare Engineering Station is responsible for the repair and testing of all major components for torpedoes and torpedo targets used by the United States Navy. It was desired that manual testing of various mechanical and electro-mechanical devices be automated to increase accuracy, repeatability, and data tracking. However, the low quantities of many items made the construction of dedicated test systems uneconomical. The solution was to provide a standardized package of automatic processcontrol and data acquisition equipment that could control testing of different mechanical and and electro-mechanical items on test beds tailored to the physical and functional characteristics of the items to be tested. This system had to provide common types of input signals, accept common output signals, be compact in size with the mobility to allow time sharing and interchangeability between test beds and be operable by a mechanic with little or no experience with computer systems.
