Abstract: An electrical device including a heat sensing circuit interrupter to enable a load to be selectively coupled to or disconnected from a power source in accordance with a level of a sensed temperature includes a relay assembly operable between a closed state when the sensed temperature is below a predetermined limit temperature, thereby enabling the coupling of the load to the power source, and an open state when the sensed temperature is above the predetermined limit temperature, thereby electrically disconnecting the load from the power source. The device further includes a sensor assembly including a light source operatively associated with a light sensor. The light sensor is configured to be sensitive to specific levels of the sensed temperature and the light source is configured to emit light along a plurality of optical paths at any one of a plurality of wavelengths sensitive to temperature.

Abstract: A terminal assembly for a device configured to indefinitely retain material therein includes a terminal shaft having a terminal head defined on an end thereof and at least one shaft including a handle and a pin member defined at opposed ends thereof. The handle includes a cam surface configured to bias the terminal head upon operation of the handle, thereby causing the pin to bias at least one compression plate within a compression area defined between the handle and the pin. The handle is configured to operate in a first position wherein the at least one compression plate is biased towards the compression area and a second position wherein the at least one compression plate is retracted from the compression area. The assembly further includes a spring component configured to retain the at least one compression plate within the compression area, wherein the material is retained within the compression area.

Abstract: An electrical receptacle has an outlet and senses the operating temperature and automatically turns off when the temperature rises above a predetermined threshold. The receptacle has a reset button that must be manually operated to enable operation of the outlet to resume.
