Abstract: An improved insulated thermocouple having no asbestos insulation material. The improved thermocouple and a method for making it are described whereby individual conductors are wrapped with high temperature fiberglass insulation and are then coated with a fiberglass binder that may be a modified silicone liquid. The individual conductors are then assembled in a parallel configuration and an outer jacket of high temperature fiberglass is applied by a braiding process. The entire assembly having the exposed outer jacket is coated with a fiberglass binder that may be a polyurethane liquid, and then cured.

Abstract: A method of forming a thermometer structure, such as a low cost clinical thermometer, wherein the thermometer enclosure structure is formed of plastic as by molding. The capillary element of the thermometer is molded about a taut wire and is removed from the molding cavity by being urged along the wire to an exterior position. The thusly removed element is utilized as a pressure-applying means on the wire to hold the wire taught for subsequent molding of a subsequent element in the mold cavity. The subsequent element is then utilized to remove the previous element from the end of the wire and replace it as the means for holding the wire taut for molding a second subsequent element about the wire. A scale is located on the capillary element by accurately determining the top of the liquid column at a preselected temperature and coordinating the placement of the scale on the element relative to said determined level.

Abstract: A thermometer adapted to be subjected to temperatures above the normal reading temperature range thereof without adversely affecting the accuracy of the thermometer in subsequent use thereof at the reading temperatures. The thermometer is adapted for use as a clinical thermometer having a normal reading temperature range of below 100.degree.F. and is constructed to provided such maintained accuracy notwithstanding subjection of the thermometer to elevated temperatures such as 140.degree.F. or more.
