Abstract
Abstract In a training device having a television system for projecting a scene such as, for example, an outdoor view, the scene may be viewed by a trainee from a simulated craft which experiences roll, pitch and other movements. The scene is optically projected onto a display screen from an image on the face of a cathode ray tube. The invention provides electronic means for moving the image on the cathode ray tube to move the projected scene on the display screen and thus simulate roll and pitch movements of the simulated craft.

Claim 1
Independent Claim
359 words
In a television projection system wherein an image on the face of a cathode ray tube is projected onto a display screen, the improvement comprising: means for moving said image in a selected direction a selected distance on said display screen, said means comprising adjustable means for moving said image in a selected direction a selected distance on the face of said cathode ray tube, said means for moving said image on the face of said cathode ray tube comprising adjustable means for adjusting the electron beam centering voltages of said tube, said adjustable means for adjusting the electron beam centering voltages comprising a plurality of potentiometers, said plurality comprising two vertical potentiometers for adjusting the electron beam vertically and two horizontal potentiometers for adjusting the electron beam horizontally, mEans connecting each potentiometer of said plurality to a respective one of a like plurality of deflection means in said cathode ray tube, and means for adjusting said potentiometers, said screen being of a spherical configuration, a spherical reflector located inside said spherical screen, said cathode ray tube being positioned so that said image is reflected from the face of said tube to said spherical screen by said spherical reflector, said means for adjusting said potentiometer comprising a frame, a ball pivot in said frame, a control handle positioned in said ball pivot, a vertical slide positioned in said frame, a horizontal slide positioned in said frame, a horizontal slot in said vertical slide, a vertical slot in said horizontal slide, one end of said control handle projecting through said slots so that vertical movement of said handle causes vertical movement of said vertical slide and horizontal movement of said handle causes horizontal movement of said horizontal slide, means connecting said vertical slide to respective taps of said vertical potentiometers and means connecting said horizontal slide to respective taps of said horizontal potentiometers so that movement of said control handle adjusts said potentiometers to move said image on the face of said tube in a direction commensurate with and a distance proportional to the movement of said control handle to move the image on said screen in a similar manner.
