IPC: A01G1/06
Filed: 1994-04-13
Abstract: PURPOSE:To provide a grafter which ensures automatic grafting because the positioning between the cross sections of the scion and the nursery stock is facilitated. CONSTITUTION:The working unit 10 having freely rotatable clamper 32 and cutter 11 is arranged between the conveyer 1 for the scions and the conveyer 2 for the nursery stocks. The working unit 10 holds and cuts young trees for the scion 88 and the nursery stock 98 in order to prepare the scion 89 and the stock 99 separately, then the grafting of them is automatically performed in sequence. At this time, one cutter 11 moves to cut both young trees at the same level from the base face, thus the positioning between both cut faces of the scion and the stock can be done easily in high accuracy by allowing the clamper 32 to move vertically in a prescribed distance. Moreover, as both young trees are cut at the same angle with the same cutter 11, the inclination angle and the shape of each cross section becomes equal to ensure these cross sections to be adhered to each other closely. In other words, the grafting operation becomes possible in increased rooting rate.

Filed: 1993-07-05
Abstract: Con frecuencia es importante una información precisa acerca de al posición de una interfaz de liquido-liquido (28,32) para el control y la automatización de procedimientos de refinación de metal fundido.  Por ejemplo, en un procedimiento electrolítico para remover magnesio de aluminio fundido, el conocimiento de la posición vertical de una interfaz (32) entre el electrólito y el magnesio, y una interfaz (28) entre el electrólito y el aluminio, facilita la remoción automática de los metales purificados. Las diferentes en la tensión superficial de las capas fluidas de una sal electrolítica fundida (30) y un metal fundido (29), produce diferentes presiones a medida que evolucionan las burbujas (57) desde las puntas verticalmente desplazadas (52)  de los tubos (34, 36), y presionan contra las capas de líquido sobre cualquier lado de sus interfaces (28, 32).  Estas presiones diferentes son detectadas por un transductor de presión diferencial (42), para limitar la cantidad de aluminio fundido purificado desde la escoria de aluminio-magnesio fundida, cuando se dirige a través de una compuerta (26) de un horno de reacción (10), sin riesgo de contaminar también el aluminio purificado con el electrólito (30) arriba de las interfaz.
