Abstract: A safety device for an industrial boiler (CHA) including electromechanical relays (REn, RS), which are connected in series in order to form an electromechanical safety chain (CH1), and at least one shunt relay (RTn) which is normally open and mounted in parallel to one of the electromechanical relays (REN). The shunt relay is controlled by an automaton (AP1) so that it is closed during a time delay. The shunt relay (RTn) is provided with a contact that is connected to an electronic circuit (CEn) and said electronic circuit (CEn) opens an electromechanical relay (RS) which is mounted in series in the safety chain when the shunt relay (RTn) is closed for longer than the time delay. Given the arrangement, in the event of an automaton failure, the time delay is ensured by the electronic circuit so that a satisfactory level of safety is guaranteed in relation to the installation.

Abstract: A steam generator device has a first and a second chamber, and walls mutually isolating the two chambers. Reagents which react together to generate steam when in mutual contact are mutually separated by a barrier, and disposed in the first chamber. An opening member forms a first opening between the chambers and a second opening through the barrier. Hence the reagents come into contact via said second opening, the reagents react thereby generating steam, and the steam flows through the first opening into the second chamber.

One version of the holder has a cylindrical sleeve fit over a wick clip holding the lower end of the wick. The cylindrical holder is well adapted for use in pillar-type candles.

Abstract: The flexible exothermic medium of this invention is composed of an exothermic agent which generates heat in contact with air, and a water-absorptive polymer and/or a second polymer other than the water absorptive polymer. The mixture thereof is pressed at a pressure of 100-8000 kg/cm2 with alcohol, a cross-linking agent or a plasticizer. This results in producing flexible united mediums. The flexibility of the exothermic medium is also obtained by irradiating it with light or heating the mixture. The exothermic medium thus prepared is so flexible as to fit any curved part the body and has excellent exothermic characteristics compared with the prior art. The heating element using these exothermic mediums is fit for various uses such as thermotherapy, body warmers, cosmetics and the like.

Abstract: An apparatus comprising a switch, a fuse, and a sensor that is capable of detecting the presence of flammable vapors and responsively changing in resistance, wherein the sensor enables the switch to supply current to the fuse which opens to shut down an appliance burner. The fuse is connected in series with a control circuit that enables a gas valve to supply gas to the burner. 65 The apparatus comprises a voltage divider circuit that includes the sensor, which upon exposure to flammable vapors, increases in resistance to provide a voltage input to the gate of a FET 100. The FET switches on and conducts a current that blows the fuse to interrupt the appliance burner control circuit and shut down burner operation.
