A brazing system includes a touch screen display and a controller circuit board having a processor and a memory. The controller circuit board is configured to be manually set by an operator to support a single torch configuration or a multiple torch configuration. The single torch configuration includes a first integrated software having first computer-executable instructions stored in the memory and configured to execute on the processor, and the multiple torch configuration includes a second integrated software having second computer-executable instructions stored in the memory and configured to execute on the processor. The multiple torch configuration supports the independent setting up of multiple brazing torches and the simultaneous use of the multiple brazing torches by multiple users during multiple independent brazing processes. The controller circuit board is operatively connected to the touch screen display and configured to allow user interaction with the controller circuit board via the touch screen display.

A switched reluctance motor is disclosed. The switched reluctance motor includes a rotor, a stator, an air gap between the stator and the rotor, and a plurality of conductive elements. The plurality of conductive elements are disposed on the rotor.

A fuel valve for regulating a flow of fuel to a combustion appliance includes a control module configured to determine fuel consumption based on a measure related to fuel flow through the fuel valve. The measure related to fuel flow through the valve may be determined using a known relationship between firing rate and the flow rate of fuel through the valve. Measurement accuracy may be enhanced by correcting for the excess air ration (also referred to as lamda).

An object of the present invention is to realize a combustion control device that reduces, when a pressure within a mixer is rapidly increased at the time of ignition of the combustion control device, the transmission of the temporarily increased pressure to a pressure sensor, that brings the pressure sensor into a non-operated state and that thereby can continue combustion in the combustion control device. Hence, a combustion control device is provided that includes: a combustion chamber which has a heat dissipation disc on a front surface and within which a combustion room is formed; a burner which is attached to the combustion chamber; a mixer which mixes a gas supplied to the burner with air; and a pressure sensor which is connected to the mixer through a pressure passage, where a pressure propagation delay means which reduces transmission to the pressure sensor caused by a temporary pressure increase within the mixer is provided partway along the pressure passage.
