Abstract: An editor apparatus for programming industrial controllers in relay ladder language, the apparatus used to provide RLL logic to control a machine axis. The apparatus includes a display for creating an axis behavior profile that represents input devices, output devices, actuators, and required movements. The apparatus gleans information from the profile and, based on the information, creates modules that include logic required to provide a program section for controlling the axis. A compiler then compiles the modules to provide an RLL program section to control the axis.

Abstract: An editor apparatus and method for programming industrial controllers in relay ladder language, the apparatus or method used to provide RLL logic to control machine tool movements in a desired sequence. The apparatus includes a display for creating a bar chart image that represents all functions in a cycle and graphically illustrates all function contingencies. The apparatus gleans function, cycle and contingency information from the image and, based on the information, creates modules that include logic required to make each function contingent upon illustrated conditions. A compiler then compiles the modules to provide an RLL program section to control the cycle.

Abstract: The invention provides a large shuttlecock which can be used with a variety of bats or racquets for a game resembling badminton or a game combining the pleasure of badminton and tennis in that the spherical head portion has a size comparable to a standard tennis ball and is designed to bounce, the shuttlecock having a spherical or partially spherical head portion made from at least an outer layer of closed cell polymeric material of predetermined parameters relating to cell size, density, tensile strength and an elongation at break and having a skirt formation attached to it in association with a core unit which increases the average density of the spherical head portion to a predetermined value.
