摘要： An apparatus and method for making electrical resistance measurements of individual powered electrodes within a glass heating furnace is disclosed. The powered electrodes are energized in pairs with electrical power supplied at a relatively low frequency, causing electrical currents flow between the pairs of powered electrodes through a pool of molten glass so as to generate heat therein. A single reference electrode is also provided within the furnace. Each of the powered electrodes is sequentially paired with the reference electrode to permit voltage and current measurements to be made. To accomplish such measurements, a relatively small high frequency electrical signal is supplied to the powered electrode, in addition to the relatively low frequency heating power supplied thereto. As a result, a measurement current flows between the selected powered electrode and the reference electrode. By selecting the high frequency measurement signal to be unrelated as a harmonic to the low frequency heating power, the effect of the heating power electrical signals on the measurement electrical signal can be greatly reduced. A current feedback circuit is provided to maintain a constant value for the high frequency measurement signal.

摘要： A bushing balance controller senses the temperature of each section of a multiple section glass fiber forming bushing by thermocouples or resistance (voltage drop) measuring techniques and injects electrical energy to all but one of the individual bushing sections and adjusts the supply of electrical energy to the entire bushing assembly thereby controlling the temperature of each individual section of the bushing. When thermocouples sensors are utilized, standard thermocouple driven temperature controllers may be utilized to provide a signal to a plurality of power packs, a primary power pack providing electrical energy to the entire bushing and smaller power packs controlling the injection of electrical energy to all but one of the bushing segments. A similar power pack and bushing control scheme accompanies the use of resistance (voltage drop) measurement techniques. Here, however, the control signal is generated by an error signal representative of the present, sensed temperature versue the set point temperature. In order to eliminate the interference between the voltage drop sensing and the injected current, an interleaving technique is utilized to sense voltage drop and inject electrical energy during alternate cycles of the applied power.

摘要： This invention proposes a method of controlling the melting rate of a glass furnace to obtain substantially constant molten glass throughput. The furnace contains a pool of molten glass and a relatively thin layer of unmelted glass batch on the surface of the pool. The furnace contents are weighed, and the batch feed is controlled by the measured weight. In essence, the melting rate is determined by the thickness of the lighter, thermally insulated batch layer, since a thinner batch layer results in more heat loss through the batch and less batch melted by the cooler molten glass. Thus, a decrease in weight indicates more molten glass withdrawal and a lower melting rate, and batch is added to increase the molten glass temperature and to melt more glass batch. In the preferred embodiment, the furnace is electrically heated at a constant rate, and only the rate of batch feed is controlled to maintain substantially constant glass throughput.

摘要： A method of detecting electrode displacement in an opaque melt of heat softenable material heated by Joule effect through said electrode by monitoring the current, voltage and electrical displacement characteristics of a body of heat softenable material and the electrodes. A relatively rapid change in monitored resistance is an indication of and often characteristic of given changes in the geometric relationships between an electrode the heat softenable material and other electrodes which can accelerate the failure of a system if corrective action is not taken. Alarm indicators, instruction print out, and/or process controls can be actuated in response to a given current voltage or resistance change. Slumping of electrodes and the direction of the slumping is indicated by the nature and magnitude of changes detected on a long term basis at least of the order of days in length. Plural electrodes and electrode pairs are monitored by multiplexing to provide a repetitive cyclic scan of the parameters between pairs. Distortion of current and voltage values is minimized, where selective portions of regular power pulses are gated for control of heating, and complex waveforms result by employing true r.m.s. values of current and voltage developed in true r.m.s. to d.c. converters. An approximation circuit for producing a d.c. voltage which is approximately proportional to the r.m.s. values of current and voltage resulting from phase controlled firing of controlled rectifiers into the electrode melt load.

摘要： A method for simultaneous compensation of a plurality of thermocouple signals where the thermocouple leads are terminated to dissimilar metals without using individual ice junctions for compensation of each thermocouple signal is disclosed. The thermocouple leads are all terminated to individual connectors as reference junctions which are held at the same temperature by a block of metal which stabilizes thermally with its environment. The temperature of the metal block is measured by an integrated circuit temperature transducer which produces an analog electrical signal proportional to the temperature detected. This signal is digitized and a microprocessor calculates the temperature of the metal block which is placed on a first data bus. Additional microprocessors are connected to the individual thermocouple leads. These microprocessors convert the thermocouple signals into an uncorrected digital temperature. The microprocessors read the temperature of the metal block from the data bus, adds this temperature to the digitized thermocouple temperature signal, retransmits the corrected digitized temperature signal on a second data bus to a central computer, converts the corrected digital temperature signal to an analog signal and transmits this signal to external devices.

摘要： A supplemental controller for a fiber glass bushing actively performs heating and cooling of a connected segment of the bushing which is otherwise controlled by a primary controller. In one embodiment, the supplemental controller performs heating by means of current injection into a connected bushing segment and cooling by means of current diversion from or around the connected bushing segment. Initial start-up and balancing operations can be performed without activation of the supplemental controller. In another embodiment of the invention, the supplemental controller heats a bushing segment by injecting current in-phase with current from the primary bushing controller and cools the bushing segment by injecting current out-of-phase with current from the primary bushing controller.
