Abstract: Procedimiento e instalación para la generación
de energía eléctrica a partir  de fuentes de energía renovables. 
     Procedimiento para la generación de energía
eléctrica a partir de fuentes  de energía renovables que comprende
una etapa de conversión de la radiación  solar directa en energía
térmica a través de un fluido térmico que es calentado  al circular
por los tubos absorbentes de unos captadores solares de un  circuito
primario; una etapa de intercambio de calor entre el fluido térmico 
del circuito primario y el agua de un circuito secundario para
generar  vapor de agua; y una etapa de turbinado donde el vapor
generado en la etapa  anterior acciona un
turbo-alternador, generándose de este modo energía 
eléctrica, en el que el vapor generado en la etapa de intercambio de
calor,  previamente a la etapa de turbinado, es sobrecalentado en
una etapa de  sobrecalentamiento con el calor producto de la
combustión de un gas de  síntesis obtenido mediante la gasificación

Title: Sistema controlador del estado de los amortiguadores en vehiculos automoviles.
Inventor: PEREZ SANZ FEDERICO
IPC: G01M17/04
Filed: 2007-04-11
Granted: 2009-12-29
Abstract: Sistema controlador del estado de los
amortiguadores en vehículos automóviles. 
     Sistema controlador basado en el empleo de una
máquina controladora, un cable de transmisión y unos medios de 
fijación a la carrocería del vehículo, de tal manera que tras la
aplicación de un impulso lineal sobre la parte de la  carrocería
sobre la que se quiere comprobar el estado de los amortiguadores
produce una oscilación que es recogida  por un "encoder"
asociado a una polea que recoge por acción de un muelle en espiral,
contando con unos medios de  lectura e impresión de los resultados.
Gracias al sistema controlador, se evita el desmontaje de los
amortiguadores, se  obtiene un sistema de medición independiente del
estado de otros elementos, rápido, sencillo y fácil de desplazar a
otra  ubicación, no precisando su verticalidad con relación a los
medios de fijación a la carrocería del vehículo.
