Abstract: In a computer aided design system, a method for converting a computer-generated symbol, or computer generated graphical entities, into an intelligent symbol involves identifying connection points to the computer-generated symbol and generating coordinates for the connection points. A symbol definition is built using the coordinates. The connection points are found by determining a perimeter substantially including the symbol and identifying graphical entities on or near the perimeter. Connectors joined to the symbol are also converted into intelligent connectors by finding coordinates for points on the connectors. A multi-symbol is generated from two or more symbols. The definition of one of the symbols forming the multi-symbol is maintained and linked to the multi-symbol such that changes in that symbol are reflected in the multi-symbol.

Abstract: In a computer aided design system, an intelligent symbol is made up of graphical entities. Connectors join the entities to other entities at connection points. When the symbol is moved, the connectivity between entities must be maintained. A connection point positioning symbol is generated, forming part of a definition of the intelligent symbol. The connection point positioning symbol has a position and an angle which describe the connection point. The connection point positioning symbol can be displayed and then hidden from view. The connection point positioning symbol allows the user to edit a connection to the intelligent symbol.

Abstract: A method and computer system for controlling an industrial process are disclosed. The industrial process has problems which adversely effect its performance. A personal computer is programmed with a database and a custom application. The database contains data describing the attributes and performance of the process to be controlled. The custom application calculates the financial value of each of the problems. The calculation of the financial value of each problem takes into account the impact of each problem on the process bottleneck. The financial values of the problems are used to prioritize the problems, allowing them to be remedied in accordance with their priority.

Abstract: A method and computer system for controlling an industrial process are disclosed. The industrial process has problems which adversely effect its performance. A personal computer is programmed with a database and a custom application. The database contains data describing the attributes and performance of the process to be controlled. The custom application calculates the financial value of each of the problems. The calculation of the financial value of each problem takes into account market conditions which affect the amount of product which could be sold if made and the marginal profitability of the product and how much optimum process time each problem takes up. The financial values of the problems are used to prioritize the problems, allowing them to be remedied accordance with their priority.

Abstract: A plumber's caddy is disclosed which provides a holder for plumbing tools, fittings and supplies. An arm permits the caddy to be secured to a member such as a ceiling joist. The arm is jointed in one or more places such that the holder can move relative to the fastener. A swivel joint is disclosed which permits rotation and tilting of the holder relative to the fastener. Hangers are provided for hanging tools from the holder.
