  • Patent number: 4420917
    Abstract: A guyline tensioner for communication towers is provided wherein the towers are of the type having a plurality of nested sections which are raised and lowered by a telescoping action. The device of the present invention provides a guying means so that as the tower is raised or lowered, a single operator can maintain equal tension on all of the guys at the same time.

  • Patent number: 4133208
    Abstract: A heat sensitive probe has a tip having a semi-conductor unit mounted on good thermal conductng material assembled in a vacuum or by other means to insure good thermal contact with the outside of the probe and hence very quick response time. The semi-conductor is connected to a suitable voltage source and has an output related to ambient temperature. Conversion of the output current to a suitable voltage uses a very stable resistor which generates a compatible voltage charge with temperature acceptable to the indicating unit, which is preferably a digital display. To avoid inaccuracies from temperature variations of the display unit, a highly stable reference voltage source and suitable divider networks constructed of temperature stable resistors of the same material as the aforementioned stable resistor at the current to voltage stage are employed.

  • Patent number: 4121459
    Abstract: Temperature profiles of objects having large areas are measured and displayed by providing a plurality of radiometric sensors, each sensor having an established field of view and being directed toward the object whose temperature is being measured. Outputs of the sensors are processed to provide maximum sensitivity within a specified temperature range and little or no sensitivity outside of the specified range. Within a specified temperature range the temperature scale is divided into a number of increments, the number of said increments dependent on the desired degree of resolution of measurement. The processed and expanded output of each of the radiometric sensors is electronically compared and categorized into the selected divisions of the specified temperature range. Electrical signals derived from this comparison are provided to columnar displays associated with each radiometric sensor whereby the range of temperature is displayed and the output of each radiometric sensor is indicated.
