Abstract: A container crane which can transport a container on a ship to a position on a land along the shortest route. The container crane comprises container transporting means for transporting a container, first and second detecting means for detecting the horizontal position and the vertical position, respectively, of a container on a ship, control means for calculating a route of movement of the container transporting means in response to information of the position of the container thus detected and for controlling the movement of the container transporting means in accordance with the calculated route of movement.

Abstract: A speed limiter device for an automobile vehicle having a combustion engine comprising an air intake manifold provided with a throttle member manual control of the accelerator pedal type which acts on the opening of the throttle member and a connecting member between these opening devices and the throttle member. The limiter device comprises apparatus sensitive to a speed parameter of the vehicle for producing a speed signal, a comparator to compare this signal with a predetermined limit, and an amplifier for the signal supplied by the comparator. The amplifier controls a drive which is sensitive to the suction in the intake manifold and acts on the throttle member so as to keep the value of the speed parameter at the predetermined limit when the limiter device is engaged. The connecting member between the opening control and the throttle member has a substantially constant length when the limiter device is not engaged and a variable length when the limiter device is engaged.
