Title: Improvements relating to regulating systems for fluid supply
IPC: F23N1/00
Filed: 1926-09-23
Abstract: 288,118. Florez L. de. Sept. 23, 1926. Divided on 287,966. Gas and spray burners.-In fluid flow regulating devices for apparatus intended to operate at a desired temperature or under other desired conditions as described in Specification 287,966, the main fluid flow is subjected to temporary periodic corrections at definite time intervals, applied in the direction necessary to maintain the desired level of operating conditions. In the application to the control of a burner heating a still for cracking hydrocarbons, the oil pipe 11 in a furnace 13 is provided with a thermocouple 14 connected to an indicating system 15 whereby the temperature is indicated by a galvanometer needle 20 moving in a path indicated by the dotted lines. A bar 26 is continuously reciprocated vertically against the needle 20, whose mid position corresponds to the desired temperature. If the temperature has varied, the needle is caused to strike one of the bell crank levers 21, 22, the lower end of which tilts a bar 27 by striking against one of the pins 30 or 31, according as the temperature is too high or too low. A shaft 36 is continuously rotated, and carries cams 34, 35, one of which contacts with the end of the bar 27 if the latter is tilted. The period of contact of the cam with the bar varies with the tilting of the bar, which depends on the amount of deflection of the needle and thus on the temperature variation, or the cam may have a contact piece at its tip only, so that a constant time of contact is obtained. The burner 12 is supplied through a main pipe 40, 42, 45, and through branch pipes 43, 44. The pipe 42 is controlled by a main valve 46, the pipe 43 by a valve 48 normally open, and the pipe 44 by a valve 49 normally closed. Assuming that the temperature is too low, and that the cam 35 is thereby caused to make contact with the piece 33, the solenoid 51 is energized and the valve 49 fully opened as long as the circuit is complete, thereby adding a puff of fuel to the steady flow. This intermittent correction of the supply continues to operate as long as the needle 20 is deflected. The air supply is controlled by a main valve 58, and by an auxiliary valve 60 controlled by the solenoid 62 which is actuated at the same time as the solenoid 51 so that the opening of the valve 60 is varied intermittently.

[Also in Division G3] A battery charging system wherein a battery 2 is charged from a variable-speed A.C. generator 1 by way of a rectifying diode 3 includes a thyristor 7 in parallel with the generator 1 and a series circuit of resistors 5, 6 and Zener diode 4 in parallel with the battery 2. When the battery voltage is low the Zener diode does not reach its breakdown voltage, thus the thyristor is not triggered and all the generated current passes to the battery. As the battery voltage increases the Zener diode breaks down for increasing periods, the thyristor becomes conductive for increasing times and diverts more and more current away from the battery thus preventing the battery from overcharge and maintaining the battery voltage at a desired value. If desired the diode 3 may be replaecd by a full-wave rectifier bridge. In a further embodiment the Zener diode circuit is connected in parallel with the generator.
