Patent ES-2043244-T3 (ES)
Inventor: AULBERS ANTONIUS PAULUS
IPC: E05B49/00
Filed: 1990-04-05
Granted: 1993-12-16
Abstract: An "electronic" lock has a thrower 5 for extending and retracting the bolt when turned by a key carrying a proper code. Turning of the thrower through a sufficient distance to shift the bolt is normally blocked by a dogging lever 20 with which the thrower lug 6 abuts. The thrower lug also sweeps a cam track 28 on a second lever 26 so as to pivot the latter during initial turning movement of the thrower away from its rest position. The second lever carries an electromagnet 30. While the electromagnet remains de-energized there is no interaction between the two levers so that the second lever 26 can pivot independently of the first 20 and turning of the thrower remains limited. When a correct key code is detected, however, the electromagnet is energized to hold the two levers together. Initial turning of the thrower thereby causes the second lever to carry the dogging lever away from its blocking position and thus free the thrower for 360 DEG  movement.

Abstract: SE DESCRIBE UN SISTEMA DE CONTROL MOTRIZ, QUE MANTIENE AUTOMATICAMENTE EL VOLTAJE MOTRIZ DE LA TOBERA DENTRO DE UN MARGEN ADECUADO. EL SISTEMA DE CONTROL MONITORIZA EL ESTADO DE LOS "SATELITES INTERMEDIOS" POSICIONADOS ENTRE GOTAS DE TINTA USADOS PARA IMPRIMIR. CUANDO ESTOS SATELITES NO ESTAN SOBRESALIENDO NI HACIA ADELANTE NI HACIA ATRAS, SE IDENTIFICA UN PRIMER PUNTO CARDINAL DESIGNADO C(L). SE DETERMINA UN SEGUNDO PUNTO CARDINAL C(H) CUANDO EL PUNTO DE INTERRUPCION DE LA GOTA DETIENE LA DISMINUCION, RESPECTO A TAL TOBERA, CON VOLTAJE MOTRIZ EN AUMENTO DE LA TOBERA. PARTIENDO DE LOS DOS VALORES CARDINALES, PUEDE CALCULARSE UNA ESCALA OPERATIVA PARA UNA TINTA PARTICULAR, Y AJUSTARSE AUTOMATICAMENTE EL SISTEMA DE CONTROL.

Abstract: This invention provides an improved process for the manufacture of 1,1,1,2-tetrafluoroethane by the reaction of HF and trichloroethylene in the presence of a catalyst to form a mixture comprising 2-chloro-1,1,1-trifluoroethane and 1,1,1,2-tetrafluoroethane and, optionally, other organic by-products. The improvement resides in conducting the reaction in a single reaction zone while recovering the 1,1,1,2-tetrafluoroethane from the mixture and recycling the 2-chloro-1,1,1-trifluoroethane and, optionally, other organic by-products from the mixture to the reaction along with trichloroethylene and HF.
