Title: Method for producing coke and apparatus therefor
Inventor: SATO YOJI
IPC: C10B47/10
Filed: 1993-09-30
Abstract: PURPOSE:To reduce the variation in the qiality of coke by charging a semicoke formed by carbonizing a coal charge and contg. remaining volatiles into a prechamber of a dry quenching apparatus and heating and baking the semicoke uniformly in both the radial and circumferential directions. CONSTITUTION:A coal charge is carbonized in a chamber oven to give a semicoke contg. 1-5% remaining volatiles derived from the coal charge. After pushed out of the oven at 600-900$0C, the semicoke is charged into a prechamber 10 of a dry quenching apparatus. Then, air is supplied uniformly over the entire surface of the semicoke layer from air supply pipes 14a, 14b, 14c, and 14d connected to an air-supply-pipe connection port installed from near the periphery of the top space 11 to the periphery of the lower part of the prechamber 10 while changing the height of a zone supplied with air. Thus is burned a combustible gas comprising the remaining volatiles to heat and bake the semicoke layer uniformly in the radial and circumferential directions.

Title: Digital timing signal generator and voltage regulating circuit
Inventor: CHIYAARUZU ROORENSU DEIBISU
IPC: G05F1/46
Filed: 1987-10-23
Abstract: A digital timing signal generator and voltage regulator circuit is provided. In one embodiment the circuit includes a delay line. The delay line operating voltage is derived from digitally encoded power/timing signals transmitted by an isolated logic control circuit. The delay line receives and propagates the digitally encoded signals. Outputs of selected stages of the delay line are tapped to provide multiphasic timing signals for use by associated logic circuits. A plurality of gates having inputs connected to various stages of the delay line receive selected timing signals as they propagate along the delay line. Increases in the operating voltage cause the selected timing signals to sequentially activate the gates. The output of each activated gate then goes high and current flows through an associated load resistor connected between the output of the gate and ground to continuously load the supply voltage and thereby regulate it. In variations of this embodiment, two and three levels of gates and load resistors are provided to progressively load the supply voltage and thereby provide additional regulation thereof. In another embodiment, a ring-oscillator comprised of CMOS inverters generates the timing signals. The ring oscillator consumes current in approximately a square relationship with increases in its supply voltage and thereby regulates the voltage.
