Processes for the conversion of hydrocarbons boiling in the temperature range of from about 80\xb0 F. In one embodiment, the head comprises a body defining a vent head chamber and having a vent head outlet. The packages also contain thermal pads which operate as a heat sink. The light emitting unit is disposed on the circuit board for emitting a visible light. Thereafter, the waveform modified signal lights is secondarily multiplexed, secondarily amplified, and secondarily demultiplexed with a waveform of amplified signal light being compensated for waveform distortion of the signal light along a transmission path of the signal light and providing an output of a waveform modified signal light. The flexible diaphragm seals a pressure chamber from the first and second outlet orifices when in the closed position and opens the first and second outlet orifices to the pressure chamber when in the open position.
