Abstract: The invention concerns a watch with a striking work including a bottom plate and a gong including two ends, the gong being secured via a first end to the bottom plate. According to the invention, the second end of the gong is also secured to said bottom plate.

Abstract: The present invention relates to an earthquake alarm that functions as an awakening and early warning mechanism which provides an audio and visual warning to a possible earthquake. The device is comprised of a free-standing arm which rests against an adjustable rod which can be manipulated to make the arm more or less sensitive to vibrations, The arm, which is pivotally mounted within a case, swings downwardly through a slot in the case when vibrations comparable to the vibrations of an earthquake cause the arm to be dislodged from its upright position. The arm is entrapped between two tabs that extend outwardly from a rotatably attached beam. The beam comprises a third tab which is secured against one distal end of a rocker arm, the opposite distal end of the rocker arm being engaged in the extended teeth of a spring loaded wheel.

Abstract: A temperature-monitoring and -witnessing device has an at least partially transparent container forming a pair of adjacent chambers at least one of which is substantially closed and formed with a passage between the chambers, a valve including a metallic shape-memory element that deforms from one shape to another shape when cooled to a predetermined transition temperature for blocking the passage when the element is of the one shape and for unblocking the passage when the element is of the other shape, a body of liquid in the one closed chamber and confined therein when the shape-memory element is of the one shape, and a dye or the like in the other chamber capable of coloring the liquid. Thus the liquid will only be colored when the element has deformed to the other shape and the device is below the transition temperature. Normally the liquid has a freezing point generally at the transition temperature.

Abstract: An alarm bell assembly wherein the working parts are located beneath and protected by the gong, and preferably also a cover for the assembly, being secured by means comprising a detector such as a micro-switch by which alarm drive is actuable when the bell is tampered with. A rechargeable battery is connected to an external control circuit such that the battery remains fully charged and supplies the alarm drive if the control circuit connection is severed.

Abstract: A mechanism for supporting a conventional portable fire extinguisher wherein the support mechanism is modified or adapted to include an audible warning device such as a siren, whistle or bell. When a person removes the extinguisher from the support mechanism an audible warning sound is generated to alerted nearby individuals of the existence of a fire or the fact that the extinguisher may be in the process of being stolen. The individuals are thus alerted to the requirement for some action on their part.
