En el interior de la carcasa y montado sobre un chasis el mecanismo se desarrolla sobre un módulo o marco cuadrado de 10 mm de ancho por 0mm de altura, realizado en un material ligero de gran resistencia y revestido o forrado de hilos de cobre formando un solenoidε electromagnético -7- con una fuerza magnética de 1 100 gr En el hueco de dicho módulo o marco se encuentra un grupo de agujas finas -8- de acero duro que presentan caras planas y cuyas cabezas se han tratado con un baño de enzima sintética luciferasa de alta resistencia, de un grosor de 1 mm y un baño de estaño, también de 1 mm de grosor , contando en el extremo de su punta las agujas con un baño adicional de hierro duroInside the housing and mounted on a chassis, the mechanism is developed on a module or square frame 10 mm wide by 0mm high, made of a lightweight material with high resistance and coated or lined with copper wires forming a solenoidε electromagnetic -7- with a magnetic force of 1 100 gr In the hollow of said module or frame there is a group of fine needles -8- made of hard steel that have flat faces and whose heads have been treated with a bath of synthetic enzyme luciferase high resistance, 1 mm thick and tin plated, also 1 mm thick, with needles in the tip end with an additional hard iron plated
Este grupo de agujas -9- atraviesa otro marco o núcleo -10- de las mismas características que el anteriormente referido pero con una fuerza de atracción electromagnética de 1 000 gr , que se encuentra separado del otro núcleo por una distancia de 3 mm y conveniente aislado del mismo para evitar que se repelan La puntas de las agujas terminan en línea sobre una pantalla plana de goma -1 1 - montada sobre un bastidor -12 - y tratada con una aleación especial de una miera de grosor muy resistente y muy flexible, de alta duración y fácil recambio, que está situada en la parte trasera de la máquina de tal manera que las cabezas del grupo de agujas coincidan con e! objetivo de la cámara El objetivo de la cámara dispone de un cristal -13- colocado interiormente
respecto al objetivo - 2 - y separaαo de este a una distancia suficiente para ampliar la imagen filmada que pasara sucesivamente a través de otros cristales -1 -, -15- y -16- alojados en el interior αei objetivo hasta alcanzar el total αel grupo de las cabezas de las agujasThis group of needles -9- goes through another frame or core -10- with the same characteristics as the aforementioned but with an electromagnetic force of attraction of 1,000 gr, which is separated from the other core by a distance of 3 mm and convenient insulated from it to avoid repellation The needle tips end in line on a flat rubber screen -1 1 - mounted on a frame -12 - and treated with a special alloy of a very thick and very flexible thickness, Highly durable and easy to replace, it is located at the rear of the machine in such a way that the heads of the needle group coincide with e! camera lens The camera lens has a glass -13- placed inside with respect to the objective - 2 - and separate from it at a sufficient distance to enlarge the filmed image that would pass successively through other crystals -1 -, -15- and -16- housed inside the objective αei until reaching the total αel group of the needle heads
El funcionamiento es como sigue cuanαo el diafragma -17- abre y cierra la proyección de la luz movido por un mecanismo -18-, conectado a un pequeño motor - 19- a través de un eje en cruz -20- hasta alcanzar veinticuatro impactos de cierre y apertura por un interruptor -21 - que también es alimentado por la misma batería, los átomos de las cabezas de las agujas se excitan en parte, produciendo quimiiumiπisceπcia por la iuciferasa y el aislamiento del cuerpo de las agujas que el solenoide primero (7) retiene con la referida fuerza de 1. 00 gr Fuerza que no es capaz e! otro núcleo de soportar pero, una vez que la luz se proyecta con el mapa de la imagen o imágenes con sus frecuencias en Hz cromática en colores básicos y sus mezclas y según la intensidad absorbida por el objetivo con filtro de entraσa de luz para obtener más frecuencia Hz con vibración más intensidad luminosa Cd acentuando más brillo Sb coπtroi del flujo luminoso Im e intensidad de iluminación Ix El núcleo -22- soporta ei grupo αe agujas en cantidad eléctrica mínima y suficiente para cerrar la fuerza de atracción 1100 El segundo núcleo -10- tiene la misión de atraer las agujas hacia sí con fuerza de 1 000, que al entrar en e! campo de atracción a la distancia primaria magnética, las agujas que corresponden al mapa de la luz son liberadas por la excitación de la luz en el componente de su aleación y en el baño referido Así, en tanto las agujas liberadas se dirigen con gran fuerza hacia el núcleo receptor que tropiezan en la cara plana interna de la pantalla -1 1 - formando los relieves fotografiados en la cara externa de la pantalla, quedando retenidas las agujas que corresponden al mapa de oscuridad o negro sin luzThe operation is as follows when the diaphragm -17- opens and closes the light projection moved by a mechanism -18-, connected to a small motor -19- through a cross shaft -20- until reaching twenty-four impacts of closing and opening by a switch -21 - which is also powered by the same battery, the atoms of the needle heads are partially excited, producing chemilysis by iuciferase and the isolation of the needle body as the first solenoid (7 ) retains with the referred force of 1.00 gr Force that is not capable of! another nucleus to support but, once the light is projected with the image map or images with their frequencies in chromatic Hz in basic colors and their mixtures and according to the intensity absorbed by the objective with light input filter to obtain more Hz frequency with vibration plus luminous intensity Cd accentuating more brightness Sb coπtroi of the luminous flux Im and intensity of illumination Ix The core -22- supports the group αe needles in a minimum electrical quantity sufficient to close the attraction force 1100 The second core -10 - It has the mission of attracting the needles towards itself with a force of 1,000, which when entering the e! field of attraction at the primary magnetic distance, the needles that correspond to the light map are released by the excitation of light in the component of its alloy and in the referred bath Thus, while the released needles are directed with great force towards the receiving nucleus that stumbles on the internal flat face of the screen -1 1 - forming the reliefs photographed on the external face of the screen, the needles corresponding to the dark or black map being retained without light
Las agujas correspondientes al mapa de la somDra, penumbra y color, son frenadas en su recorrido con menos brusquedad y presión según son liberados sus átomos por la menor y leve luz que en la escala supone la totalidad del relieve por reacciones fotoquímicas de regeneración en cadena Con ello se consigue la perfección y la copia real de lo fotografiado porque las agujas pueden estar unidas en grupo y luego individualmente cada una de ellas, quedando pocos poros entre ellas, más la pantalla de gema elimina esa pequeña distorsión gracias a les impactos de veinticuatro impulsos por segunde que se pueden medir En la fotografía de la figura 2, una pequeña máquina que trabaja solamente con
una sola aguja según lo descrito anteriormente pero esta pequeña maquina es mucho más sencilla con menos mecanismos y sin diafragma que tal como esta o reducida al tamaño de un reloj es αe utilidad para las personas invidentes que, al situar el objetivo micro hacia ios monitores de los semáforos distingue los colores de las luces notando el interesado las mismas frecuencias en Hz como los videntes lo que se traduce en entrada y salida de la aguja por el orificio de tal manera que no necesita de pantalla de goma que, por el tacto y la presión y/o tocando otra parte del cuerpo el invidente distingue los impulsos de cada color en su cuerpo, tanto los tres colores situados en los semáforos como el resto de los siete colores básicos del espectro y sus mezclas La fotografía de la figura 3 es el prototipo de pruebas de experimentación descrito anteriormente La figura 4 es la misma inventiva descrita al principio pero cambian algunos mecanismos por la perfección y variedad de la idea que, cambiándose los cristales que aumentan la imagen por un micro procesador -23- similar y a modo σe ejemplo como es un teclado que en lugar de disponer de las letras para informar, son un grupo de finos caDles que distinguen la luz, la sombra, la oscuridad y los colores lo mismo que las agujas relatadas y, que esta base es de tamaño que abarca el recuadro interior de la toma de la imagen por mediación del zoom, esta información pasa a un microordenador -24- que dispone de la entrada para un disco -25- con un programa especial con memoria pasando la información a un bloque de agujas -26- que realiza la misma función de la formación de relieves, quedando el resto de mecanismos dispuestos y ubicados sobre el bastidor que el modelo anterior
The needles corresponding to the map of the shadow, penumbra and color, are braked on their way with less abruptness and pressure as their atoms are released by the slightest light that on the scale represents the entire relief by photochemical reactions of chain regeneration With this, perfection and the real copy of the photographed are achieved because the needles can be joined in a group and then individually each of them, leaving few pores between them, plus the gem screen eliminates that small distortion thanks to the impacts of twenty-four impulses per second that can be measured In the photograph in figure 2, a small machine that works only with a single needle as described above, but this small machine is much simpler with fewer mechanisms and no diaphragm, such as this one or reduced to the size of a watch, it is useful for blind people who, when placing the micro lens towards the monitors of the traffic lights distinguish the colors of the lights, noting the interested party the same frequencies in Hz as the clairvoyants, which translates into entry and exit of the needle through the hole in such a way that it does not need a rubber screen that, by touch and By pressing and / or touching another part of the body, the blind person distinguishes the impulses of each color in his body, both the three colors located at the traffic lights and the rest of the seven basic colors of the spectrum and their mixtures. The photograph in Figure 3 is the experimentation test prototype described above Figure 4 is the same inventiveness described at the beginning but some mechanisms change for the perfection and variety of the id ea that, changing the crystals that increase the image for a similar microprocessor -23- and as an example such as a keyboard that instead of having the letters to inform, are a group of fine strings that distinguish light, shadow , the darkness and the colors as well as the related needles and, since this base is of size that encompasses the inner box of the image taking by means of the zoom, this information passes to a microcomputer -24- that has the input for a disc -25- with a special program with memory passing the information to a block of needles -26- that performs the same function of the formation of reliefs, the rest of the mechanisms being arranged and located on the frame as the previous model
