7. The projectable pointer
The projectable pointer, also known as laser pointer, is based on the shadow produced by an opaque body that moves near the projected plate, this shadow is the one that it would use as a pointer. To this end, it designed an articulated system that allowed to move, at the will of the speaker, a point or points next to the projection plate, which allowed to indicate the areas of interest in the transparency. Torres Quevedo expresses the need for this invention: 'Well-known are the difficulties encountered by a teacher to illustrate his speech, using luminous projections. You need to stand in front of the screen taking care not to hide the projected figure to draw the attention of your students on the details that interest them most and show them with a pointer '.
6. Airships
In 1902, Leonardo Torres Quevedo presented at the Academies of Sciences of Cantabria and Paris the project of a new type of airship that solved the serious problem of suspension of the nacelle by including an inner frame of flexible cables that gave rigidity to the airship by effect of the internal pressure. In 1905, with the help of Captain Alfredo Kindelán, Torres Quevedo directed the construction of the first Spanish airship in the Army Military Aerostat Service, created in 1896 and located in Guadalajara. They finish with great success, and the new dirigible, the 'Spain', performs numerous exhibition and test flights. Perhaps the most important innovation in this airship was to make the balloon three-lobed, so that it increased safety. As a result of this fact begins the collaboration between Torres Quevedo and the French company Astra, who came to buy the patent with a cession of rights extended to all countries, except Spain, to enable the construction of the airship in the country. Thus, in 1911, the manufacture of the airships known as Astra-Torres began. Some copies were acquired by the French and English armies from 1913, and used during the First World War, in many different tasks, mainly of protection and naval inspection. In 1918, Torres Quevedo designed, in collaboration with the engineer Emilio Herrera Linares, a transatlantic airship, which they called 'Hispania', which reached patent status, in order to carry out the first Atlantic aerial crossing from Spain. Due to funding problems the project was delayed and it was the British John William Alcock and Arthur Whitten Brown who crossed the Atlantic nonstop from Newfoundland to Ireland in a twin-engine Vickers Vimy biplane in 16 hours and 12 minutes.
