Abstract: A method and device for displaying electronic text on a screen is disclosed, comprising presenting text as a single word display of a particular duration plus a non-text gap, and continuing this single word duration plus gap presentation until all desired text has been sequentially displayed; wherein the speed of the text display is created by repetition of the duration plus gap, and wherein varying the gap relative to the duration creates a different flow of text presentation. The speed of the display is controllable by the reader using a control pad. This method and device permits text to be easily read on a limited viewing area.

Abstract: A system is provided for automatically maintaining the drill steel on its proper path during drilling. The drill is mounted at the end of an extendable boom, the extension of which can be controlled hydraulically. The orientation of the drill steel with respect to the boom is also controlled hydraulically. The boom can be elevated by a hydraulic system to drive the drill steel into the strata above. The position of the drill is calculated by a controller by means of several sensors. The controller then controls the extension of the boom and boom angle as well as the orientation of the drill with respect to the boom in order to maintain the drill steel in the proper position throughout the drilling process.
