Abstract
Abstract An electrical pulsing unit in the pusher ram drive emits a pulse for every preselected incremental distance traveled by the ram from the face of the oven at the start of the push to the completion of the push. The pulses are received in the quench car locomotive and are converted to signals that show the position of the ram during its travel. The quench car has a similar pulsing unit, and pulses from this unit are converted to signals that show the position of the quench car. The quench car locomotive operator can then coordinate the signals to achieve proper coke distribution in the quenching car.

Claim 1
Independent Claim
204 words
A SYSTEM FOR SYNCHRONIZING THE TRAVEL OF A PUSHER RAM IN A COKE OVEN CHAMBER WITH THE TRAVEL OF A COKE QUENCHING CAR RECEIVING HOT COKE FROM THE OVEN CHAMBER AND PROPELLED BY A LOCOMOTIVE RELATIVE TO SUCH OVEN CHAMBER, WHEREIN THE IMPROVEMENT COMPRISES: A. SWITCH MEANS ACTIVATED BY SAID PUSHER RAM AS IT MOVES TOWARD AND INTO AN OVEN CHAMBER TO BE PUSHED AND CLOSING AN ELECTRICAL CIRCUIT, B. A PULSE TRANSMITTER IN SAID CIRCUIT WHICH IS ACTIVATED WHEN SAID SWITCH MEANS CLOSES THAT EMITS PULSES, C. ELECTRICAL RECEIVER MEANS IN SAID LOCOMOTIVE THAT RECEIVES SAID EMITTED PULSES AND THEREAFTER ENERGIZES AN ELECTRICAL CIRCUIT WHEREIN THERE IS D. A FIRST STEPPING MOTOR THAT ACTUATES SAID PUSHER RAM IN A STEP-BY-STEP MANNER RESPONSIVE TO THE RECEIVED PULSES AND CIRCUIT ENERGIZATION, E. A PULSER IN SAID QUENCHING CAR THAT IS ENERGIXED BY A SIGNAL EMITTED BY SAID RECEIVER, F. A SECOND STEPPING MOTOR THAT IS ENERGIZED BY SAID PULSER AND THAT MOVES SAID QUENCHING CAR IN A STEP-BY-STEP MANNER IN SEQUENCE WITH SAID PUSHER RAM, AND G. INDICATOR MEANS IN SAID LOCO,OTIVE THAT IS RESPONSIVE TO THE ACTUATION OF SAID STEPPING MOTORS AND INDICATES THE RELATIVE POSITIONS OF THE PUSHING RAM AND THE QUENCHING CAR.

Claim 3
Dependent Claim
49 words
The invention of claim 1 including: a. means actuated by said pusher ram at the end of its stroke for de-energizing said circuitry; and b. a reset pulser energized by said means that sends electrical pulse signals to both of said indicators whereby they are reset to initial positions.
Claim 4
Dependent Claim
27 words
The invention of claim 2 including: a. switch means, actuated when said indicators return to the initial position, that de-energize a power circuit to said pulse transmitter.
Claim 5
Independent Claim
188 words
A system for synchronizing the travel of a pusher ram in a coke oven chamber with the travel of a coke quenching car receiving hot coke from the oven chamber and propelled by a locomotive relative to such oven chamber, wherein the improvement comprises: a. switch means activated by said pusher ram as it moves toward and into an oven chamber to be pushed that closes an electrical circuit; b. a first pulser energized when said switch closes that emits pulse signals as said pusher ram moves into said oven chamber; c. a first stepping motor actuated to turn in one direction responsively to said pulse signals; d. a second pulser that emits pulse signals as said quench car receives coke pushed from said oven chamber and moves relative thereto; and e. means sending electrical signals from said second pulser to said stepping motor whereby said stepping motor turns in a direction opposite to said one direction, said stepping motor being so constructed that it does not rotate when the pulse signals from said first and said second pulsers are equal in number during any period of time.
Claim 6
Independent Claim
188 words
A system for synchronizing the travel of a pusher ram in a coke oven chamber with the travel of a coke quenching car receiving hot coke from the oven chamber and propelled by a locomotive relative to such oven chamber, wherein the improvement comprises: a. switch means activated by said pusher ram as it moves toward and into an oven chamber to be pushed that closes an electrical circuit; b. a first pulser energized when said switch closes that emits pulse signals as said pusher ram moves into said oven chamber; c. a first stepping motor actuated to turn in one direction responsively to said pulse signals; d. a second pulser that emits pulse signals as said quench car receives coke pushed from said oven chamber and moves relative thereto; and e. means sending electrical signals from said second pulser to said stepping motor whereby said stepping motor turns in a direction opposite to said one direction, said stepping motor being so constructed that it does not rotate when the pulse signals from said first and said second pulsers are equal in number during any period of time.
Claim 7
Dependent Claim
103 words
The invention of claim 4 wherein: a. said stepping motor rotates in a direction to move said quench car at a faster rate of speed when the number or pulses received from said second pulser is less for said period of time than the number of pulses received from said first pulser; and wherein; b. said stepping motor, when it receives more pulses from said second pulser than from said first pulser, actuates a rotary cam limit switch to effect control of the speed of said quench car, to thereby effect a balance of position between the quench car and the pusher ram.
Claim 8
Dependent Claim
52 words
The invention of claim 4 wherein: a. said steping motor, when it receives more pulses from said first pulser than from said pulser actuates a rotary cam limit switch to effect control of the speed of the quench car to thereby effect a balance between the quench car and the pusher ram.
