Abstract
Abstract Apparatus for compensating the misalignment of a car for charging coal into a coke oven, wherein a central control roughly positions the car in response to pulses from a digital tachometer located on the car. Fine positioning of the car is performed by utilizing the stored pulses of a skew counter and an approach counter under control of signals produced by limit switches carried by the car and actuated by positioning elements on the oven.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
231 words
An apparatus for accurately stopping at a station a vehicle oriented obliquely with respect to its path of travel so that the effect of the obliqueness is compensated for, comprising: a. first and second actual actuating elements located on opposite sides of the path of travel of the vehicle; b. first and second sensors for cooperation with said actuating elements positioned on opposite sides of the vehicle, said sensors producing triggering signals, simultaneously only when the obliqueness of the vehicle is zero; c. means for generating pulses in proportion to distance traveled by the vehicle; d. an oblique counter connected to said first and second sensors and said pulse generating means for accumulating a count during the time interval between the triggering signals from said first and second sensors, said count being proportional to the obliqueness of the vehicle; e. a preset approach counter initially containing a count proportional to the distance between said actuating elements and the station measured along the path of travel; f. means for modifying said preset count by a predetermined fraction of the contents of said skew counter; g. means for applying the output of said pulse generating means to said approach counter following the trigger signal of said second sensor to reduce the count in said approach cOunter; and h. means responsive to a predetermined count in said approach counter to stop the vehicle. 2.

Claim 3
Dependent Claim
22 words
The invention claimed in claim 1 wherein said first and second sensors are vane limit switches and said actuating elements are vanes.
Claim 4
Dependent Claim
30 words
The invention claimed in claim 1 wherein said modification of said preset count in the approach counter is performed by subtracting half of the contents of the oblique counter therefrom.
Claim 5
Dependent Claim
61 words
The invention claimed in claim 1 wherein said modification of the preset count in the approach counter is performed by adding half of the contents of the oblique counter, and means for applying the output of said pulse generating means to a said approach counter following the trigger signal of said first sensor to reduce the count of said approach counter.
