Abstract: A control system of a water heater apparatus with a combustible gas burner is presented where the apparatus includes a pilot burner with an intermittent-type pilot flame, a main burner, a pilot valve and a main valve, a control unit, a flame detection electrode, introduced into the flame of the pilot burner, and which is configured to conduct an ionization current. The control unit is configured to measure/detect a variation involving increase/decrease of the intensity of ionization current detected, the variation in intensity of ionization current being generated during the change between a first condition, in which the ionization current identifies the ignition state of only the pilot burner, and a second condition, in which the ionization current identifies the simultaneous ignition state of the pilot burner and the main burner so that, by detection of the measurement/variation of ionization current, the effective ignition of the main burner is recognized.

Abstract: A method for modulating a valve regulating the flow rate of gas towards a burner is presented. The valve with the associated closure member configured to operate with a predetermined characteristic curve, the flow rate delivered being proportionally related to the strength of a first current signal sent to the modulator such that the flow rate can be modulated, using the proportionality, within a range of modulation between a maximum flow rate and a minimum flow rate. To deliver controlled gas flow rates that are below the minimum flow rate, the modulator is driven with a second PWM voltage signal capable of generating a particular second PWM current signal, to move the closure member of the valve according to the second signal. First and second time intervals correspond to successive durations of high signal and low signal, respectively, the sum being equal to a period of the second signal.

Abstract: Pincers for removing residual dental roots by the application of a contrary force on the mandible and maxilla on a pre-fixed screw. It is constructed in such a manner as to enable the strength of the operator to be multiplied and the final movement of the pincers to be reduced. The operator will need to apply minimal force and thus the procedure becomes simple and safe, thereby preserving the underlying bone structure and facilitating implant osseointegration. Likewise the device can be easily sterilized and assembled/dismantled easily because of the small number of moving parts. Further, there is no need for the mouth to be opened so widely, which results in less movement and less trauma caused by excessive opening of the patient's mouth, and it adapts to the irregular profile of support on the dental arch.
