Abstract: An elongated pipe tower extends upwardly at an acute angle from vertical with snow making nozzles in an upper end portion of the tower. Supply connections are provided at the lower end of the tower for connection to remote sources of air under pressure for supplying air and water under pressure to the nozzles for discharge into ambient atmosphere for manufacturing snow in sub-freezing conditions. The upper end portion of the tower protrudes upwardly at an angle from the tower and the nozzles are positioned on the outer side of the tower upper end portion facing outwardly away from the tower and the tower base. The nozzles are positioned such that the combined resultant thrust of the suspended weight of the tower itself and the thrust of discharged air and water under pressure through the nozzles is caused to be in substantial alignment with the tower, thereby preventing application of undue stress on the tower and permitting the use of a lightweight pipe tower.

Abstract: An automated system to draw detailed networks for use in various types of engineering analysis and simulations. Nodes can be activated from a set of available node sites. Elements between nodes are automatically drawn by specifying the node start and node end of each element and selecting a draw command and utilizing stored data arrays and graphical software system for input and display of network based computations. A speed draw command can alternatively activate the next node site for the direction command selected and connect the starting and ending nodes with the next available element in a single command. Elements can also contain various attribute types that are displayed and edited on an element toolbar when elements are selected. Values stored in unique data arrays are then available for use in engineering computations.
