Abstract: An emergency intercommunication system for an elevator has an interphone unit and an intercommunication command switch located in an elevator car. A telephone number input apparatus for inputting the desired telephone number is provided in an elevator hall, in connection with a register apparatus for storing the input telephone number. An intercommunication command detecting section for detecting the actuation of the switch is provided in connection with an emergency call apparatus for automatically dialing the stored telephone number to connect the interphone unit with a telephone having the telephone number when the actuation of the switch is detected by the detecting apparatus. Preferably, an identification number input apparatus is provided in the elevator hall so that the register apparatus stores the telephone number only when it is input together with a predetermined identification number.

Abstract: An apparatus for controlling a hydraulic elevator in which a bias pattern signal for operating an electric motor at such a low speed that the cage will not move is superposed on a running pattern signal for running the cage, and the electric motor is controlled by the thus superposed pattern signals. Therefore, the amount of oil flowing into or out of the cylinder increases nearly in synchronism with the start of the running pattern, and the cage moves smoothly without generating vibrations.
