Abstract: Dispositivo de limpieza manual. 
     Del tipo de los constituidos mediante la
combinación de un elemento de limpieza propiamente dicho (1) y un
palo o mango (2), pudiendo ser dicho elemento de limpieza (1) una
mopa, una bayeta u otro similar, la invención se centra en el hecho
de que un soporte de dicho elemento de limpieza (1) se acopla al
palo o mango (2) con libertad de giro sobre el imaginario eje de
éste último, materializándose dicho soporte en una rueda, polea o
similar. De esta manera al desplazar el elemento de limpieza (1)
sobre la superficie a limpiar, un accionamiento transversal con
respecto al eje del palo (2) se traduce automáticamente en un
movimiento giratorio del elemento de limpieza (1) con respecto al
palo (2) que se materializa a su vez en un movimiento giratorio del
elemento de limpieza (1) con respecto a la superficie a limpiar, lo
que potencia considerablemente la efectividad de la maniobra.

Granted: 2014-04-28
Abstract: Proceso integrado de recuperación de fibra de carbono a partir de tejido o cinta de carbono preimpregnada. El proceso permite la recuperación por una parte de fibra de carbono con un contenido en resina prácticamente despreciable, y por otra de la resina del tejido polimerizada; es decir, en forma de residuo inerte.#El proceso se fundamenta en eliminar la resina parcialmente polimerizada con un proceso simple energéticamente. El proceso se basa en aplicar calor para disminuir la viscosidad de la resina; y presión para lograr que la resina fluya. Al final del proceso se obtiene separada la resina polimerizada y la fibra reciclada. Con el fin de conseguir una eliminación más exhaustiva de la resina el proceso termina con una limpieza con disolvente como por ejemplo acetona.#El proceso es aplicable en aquellos casos que el material ha caducado pero que la resina ha sufrido poca polimerización de forma que puede fluir al ser sobrecalentada y al aplicar una ligera presión.#En aquellos casos que se requiera una eliminación más exhaustiva de la resina, el sistema permite el acoplamiento de una unidad de lavado con disolvente como por ejemplo acetona.
