Inventions Early on, Marin devised several labor-saving devices, including a device that improved the functionality of a watermill on the Arandilla river; one that improved the working of a fulling mill; and another used to improve the cutting of marble in the quarries of Espejón. He also came up with a device used to whip horses during the process of threshing, and another that made cloth pads.

Fan (implement)
A handheld fan, or simply hand fan, is a broad, flat surface that is waved back and forth to create an airflow. Generally, purpose-made handheld fans are folding fans, which are shaped like a sector of a circle and made of a thin material (such as paper or feathers) mounted on slats which revolve around a pivot so that it can be closed when not in use. Hand fans were used before mechanical fans were invented. Fans work by utilizing the concepts of thermodynamics. On human skin, the airflow from hand fans increases the evaporation rate of sweat, lowering body temperature due to the latent heat of the evaporation of water. It also increases heat convection by displacing the warmer air produced by body heat that surrounds the skin, which has an additional cooling effect, provided that the ambient air temperature is lower than the skin temperature, which is typically about . Next to the folding fan, the rigid hand screen fan was also a highly decorative and desired object among t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
