Abstract: An improved elevator control system for maintaining a properly controlled interval between a plurality of elevator cars. The system includes means for detecting the time interval or spatial interval between a preceding elevator car, an intermediate elevator car and a succeeding elevator car. When the interval between the preceding and intermediate elevator cars is more than the interval between the intermediate and succeeding elevator cars, the intermediate elevator car is accelerated, while when the former interval is less than the latter interval, the preseding or succeeding elevator car is accelerated for maintaining a reasonable interval between these elevator cars.

Abstract: A system for controlling a plurality of elevator cars in which a hall call originating means is disposed at each floor landing so that passengers standing at the floor landing can designate the floors to which they want to be transferred, and a target floor memory is provided for each elevator car to store information as to the floors at which such elevator car has already been instructed to stop. In the system, means are provided to detect the coincidence between the floor numbers designated by a hall call originating from one of the floors and the floor numbers stored already in the target floor memory for each elevator car so that the elevator car for which the coincidence occurs in a greater number can be preferentially selected to be stopped at the specific floor.

Abstract: A circuit breaker having an actuating system comprising a signal responsive valve member of large diameter and a making force imparting valve member of small diameter connected to each other by an actuating rod so that a first differential force relationship can be established therebetween. A movable valve seat of diameter smaller than that of the making force imparting valve member is movable toward and away from the signal responsive valve member so that a second differential force relationship can be established between the two valve members when the movable valve seat engages the signal responsive valve member to limit the effective area of the latter. The movable valve seat is moved toward and away from the signal responsive valve member and fluid under pressure applied to the signal responsive valve member is suitably controlled so as to selectively bias the actuating rod in one of the making and breaking directions. A control valve member is disposed in proximity to the movable valve seat so that it moves in response to the movement of the actuating rod in the breaking direction for controlling the application of the fluid pressure to the signal responsive valve member. This control valve member acts to reduce the moving distance of the movable valve seat following the movement of the signal responsive valve member so that the movable valve seat can take a floating position ready to move in the making direction.
