Abstract

In a horizontal coke oven battery with at least one coke receiving device movable along one longitudinal side of the battery and at least one coke driving device movable along an opposite longitudinal side of the battery, an apparatus for determining the relative position of the coke receiving device with respect to the coke driving device and for activating the coke driving device when its position corresponds with that of the coke receiving device, comprising, a first wheel mounted on the coke receiving device for rotation with the movement of the coke receiving device, a first angle encoder connected to the first wheel for producing a first signal corresponding to the location of the first wheel and the position of the coke receiving device along the coke oven, and an input storage in the form of a magnetic disc connected to the first angle encoder for recording and storing the signal. A second wheel is mounted on the coke driving device for rotation with the movement of the coke driving device and a second angle encoder is connected thereto for producing a second signal which corresponds to the rotation of the second wheel and the position of the coke driving device along the coke oven. A comparator is connected to the second signal encoder for receiving the second signal and a data link is provided between the comparator and the input storage of the coke receiving device so that the first signal from the coke receiving device can be impressed on the comparator. An activator is connected to the comparator for activating the coke driving device when the first signal corresponds to the second signal indicating a corresponding positional relationship between the coke receiving device and the coke driving device.
