Abstract: The invention relates to a cooking vessel (1) comprising a cap (2) equipped with an end wall (3). According to the invention, the end wall (3) comprises a housing (6) accomodating at least one bimetallic element (30a, 30b) that adopts a cold stable first position when the temperature is below a predetermined temperature and toggles into a hot stable second position when the temperature is above the predetermined temperature, and vice versa, the transition from the first stable position to the second stable position generating an audible signal designed to be perceived by a user or by an external device.

Abstract: A monitoring cooking thermometer includes a shape memory alloy activated probe for entering into food being cooked. A clockwork mechanical mechanism in a body fits to the top of the probe. When the food reaches a predetermined temperature a mechanical bell is sounded and a flag is exposed outside the body.

Abstract: A triggering device for fire and smoke alarms in which a biased pin member is held in armed position by a latch element which is releasable when a bimetallic disc senses and responds to a selected temperature condition. The response of the disc is transmitted through a ball or antifriction element to which is imparted a lateral force for moving the latch element out of engagement with the pin member. The pin member is spring biased to urge the pin member against a member serving to cause actuation of the alarm.

Abstract: A temperature change sensing device which is adapted to be used in conjuction with an audible or visual warning device, comprising a temperature sensitive means for rotating a first disc, having disposed about its surface at least one of a first cooperative coupling means. These first cooperative coupling means coincide with a second cooperative coupling means located on a second disc. When the ambient temperature reaches the preset temperature of the sensing device, the temperature sensitive means rotates the first disc such that the first cooperative coupling means aligns with the second cooperative coupling means on the second disc. The second disc is then thrust toward the first disc by a biasing means, which has attached to it a means for tripping a visual or audible warning device.
