Abstract
Un aparato perfeccionado de rayos X, que comprende un dispositivo de compensación de peso que está suspendido de un techo y que incluye un carro que es desplazable a lo largo del techo bajo la influencia de un motor eléctrico, estando suspendido de dicho carro un componente desplazable por medio de un miembro de conexión flexible, caracterizado porque el motor eléctrico está conectado a una salida de señales de un circuito de control que está conectado a un dispositivo transductor que genera una señal de salida en el circuito de control en respuesta al desplazamiento relativo del carro con respecto al componente suspendido del carro, aplicando dicha salida de señales una señal de salida al moto eléctrico en tanto que el desplazamiento relativo del carro y del componente se desvíe de un valor de referencia.
