Abstract: This invention is a flexible heater or cooler which includes a flexible, conformal, thermally conductive container filled with thermally conductive material. A thermal element within the container or in contact with the outside of the container provides heat to the container or removes heat from the container. The thermal element is powered by a low voltage direct current electrical source. A sensor for determining the temperature of the thermally conductive material is also included. The thermal element, electrical source, and sensor are in communication by connectors with a solid state continuous temperature controller. In operation, the electrical source provides power to the thermal element, thereby heating or cooling the thermally conductive material within the container. The temperature in the container is determined by the sensor and the controller controls the power delivery to the thermal element in response to the setting on the controller and the temperature in the container.

Abstract: A laminated tubular connector for splicing or terminating electric conductors, comprising an outer layer of a heat shrinkable dielectric material, e.g., polyethylene terephthalate, and an inner layer of relatively soft, self-adhesive, low temperature flowable thermoplastic material, preferably a polyvinyl acetate composition. When heat is applied to the connector, the outer layer shrinks and the inner layer functions as a sealant and a cushioning agent. In some applications, the adhesiveness of the inner layer may be used to hold the connector in place during subsequent operations by pinching the connector so that the depressed portions of the tube adhere to each other prior to heating the connector to shrink the outer layer.
