This paper aims to optimize the weighing control system and compensate weighing error for weighing control system of coal mine paste-filling weighing control system.

The process of the paste-filling weighing control system is analyzed and the mathematical model of the paste-filling material weight is established. Then, the back-propagation (BP) neural network is used to optimize the control system and compensate the weighing error.

Without the BP neural network, the weighing error of the paste-filling control system is more than 3 per cent, whereas after optimization with the BP neural network, the weighing error is less than 1 per cent. With the simulation results, it is seen that the weighing error of the paste-filling control system decreases and the accuracy of the weighing control system improves and optimizes.

The method can be further used to improve the control precision of the coal mine paste-filling system.

Production of cationic resin at International Paint's Ladywood plant in Birmingham is now being achieved with the use of Bofors' computer controlled electronic weighing system.

A new, digital, weigh filling control system installed at Swift Adhesives in Cambridgeshire has enabled the Company to fill boxes of its hot melt glue produet more efficiently than a previous, pneumatic based system.

Beneath the glossy jet‐set glitter, air transport is a desperately sick industry. Since 1966 the net profit on revenue of the world's schedule airlines has slipped from 6% to near vanishing point.

Rexson Systems,a leading company in dispense valve design, have claimed a first for the paint industry with the commissioning of a high accuracy gravimetric system designed to dispense and blend finished paints and drier solution directly into the end user's can.

Controlling paint production. Paint users are placing higher demands on the manufacturer. All paint producers should now consider data acquisition — and possibly automated paint manufacturing if the volumes of certain products will justify it.

This paper aims to study a modular method for designing a paste filling station (PFS) for a coal mine (CM) to reduce the PFS’s input cost and achieve reutilization.

Modular design criteria for the PFS are proposed and a modular division (MDiv) model and an evaluation method are established. The correlation-strength matrix of the PFS parts expressed in the form of rough numbers is transformed into a fuzzy equivalent matrix. The theory of rough sets and the fuzzy clustering method are introduced for PFS MDiv. The evaluating method is established for the PFS MDiv scheme based on the principle of fuzzy comprehensive evaluation.

Taking a particular CM PFS as an example, the above method is used to modularize the PFS, and the optimal division of the PFS is finally determined via the above evaluation system. Applying this method solves the problem of high cost investment in the initial stage of PFS construction.

The theory of rough sets and the fuzzy clustering method are introduced for PFS MDiv. An evaluating method is established for the PFS MDiv scheme based on the principle of fuzzy comprehensive evaluation, thereby providing new ideas for PFS transformation and reutilization.

The latest technology in high solid paints and their application by high speed electrostatic disc or bell was discussed at a symposium organised by Tl Drynamels at the Post House Hotel, Nottingham, on April 7th. Papers were given by equipment manufacturers, an industrial user, as well as Tl Drynamels specialists. Delegates came from several industries, but particularly the domestic appliance manufacturers.

The purpose of this paper is to review the most recent innovations in sensor technology for better quality in packaging. Checking for container seals, damaged product, contaminates as well as tracking product to meet government requirements.

In-depth interviews with both the exhibitors and integrators of sensors at the recent PackExpo show.

Sensor technology continues to address an ever increasing number of packaging applications including quality, safety, product tracking, correct labeling as well as counting, weighing and other more traditional applications.

Sensor technology advances with greater use of X-ray, magnetic detection and remote chemical monitoring that are addressing an ever increasing number of packaging applications including quality, safety as well as counting, weighing and other more traditional applications.

Customers will learn about the latest in X-ray, magnetic sensing and the application of vision, weighing and counting technologies for improved products as they pass through the packaging phase of production.

IT is difficult to imagine the world of Work Study without the urbane ubiquity of Russell Currie, whose death on 28 August we deeply regret to record. Although he had been officially in retirement for a year or two his presence was immanent in any important gathering of those who had so long looked to him for the leadership that was always forthcoming. We can fittingly borrow an epigram he coined at the London Congress in 1963 as apt at this time. ‘The sun shone to greet your arrival; the skies weep for your departure.’
