| Number | Title | Issue Date |
| 4179926 | Multiple signal thermoparticulating coating A composition is disclosed of a solution of a resinous carrier and at least two compounds which thermoparticulate at different temperatures between 60° and 200° C. A coating is made by applying the composition to a portion of an electrical apparatus exp... | 12/25/1979 |
| 4133036 | Method and system for monitoring a physical condition of a medium A method and system for approximately indicating the temperature of molten steel is described. A temperature sensor is immersed in the molten steel and produces an output signal which indicates the temperature sensed by the sensor. The temperature output ... | 01/02/1979 |
| 4086805 | Apparatus for evaluating measurement signals Apparatus for evaluating a measurement signal having an initial transient issuing into a more stationary value include equipment for monitoring the rate of change of the measurement signal. This monitoring equipment issues a control signal when that rate ... | 05/02/1978 |
| 4065758 | Alarm detector responsive to rate of change of a monitored condition A physical quantity such as temperature, infrared radiation or smoke is detected by means of a conversion device for emitting an alarm signal whose amplitude is representative of the intensity of the physical quantity. The detector comprises a unit for me... | 12/27/1977 |
| 4019364 | Method and apparatus for testing welds between dissimilar metals by using the seebeck effect To test certain structural characteristics of a weld formed between two dissimilar metals in order to test the quality, or structural integrity, of the weld, the emf generated at the weld bond interface during welding, as a result of the Seebeck effect (t... | 04/26/1977 |
| 4009615 | Self contained electronic digital thermometer A self-contained electronic digital thermometer is in the form of an elongated probe has a temperature transducing thermistor at a front end and an electronic digital display at a rear end. Circuitry housed within the probe converts the voltage across the... | 03/01/1977 |
| 3975240 | Process and system for determining the end of a coking process Separate temperature measuring elements are positioned on the outer wall surface of the riser of at least one oven chamber of a coke oven. During production of coke, the temperatures measured will be different. Upon completion of the coking process the di... | 08/17/1976 |
| 3938386 | Method and apparatus for monitoring temperatures during catalytic regeneration from a continuously moving infrared scanning and detection unit fixedly mounted aboard an aircraft Careful and accurate indication of regeneration temperatures of catalysts associated with the refining of hydrocarbons such as occurring in catalyst-aided hydrocracking and catalyst-aided reforming processes--in real time--occurs by monitoring--from an ov... | 02/17/1976 |
