Abstract: A method and system are disclosed for providing fuel and air to a furnace. The furnace includes a plurality of burner assemblies, each with its own air valve for controlling the flow of combustion air therethrough. A sensing instrument for each burner assembly senses a condition reflecting the individual performance of that particular, separate burner assembly. A controller is coupled with the sensing instruments and with the air valves of the burner assemblies for controlling each individual air valve in response to the performance reflecting condition sensed by each sensing instrument. This results in individual control of the performance of each burner assembly of the set of burner assemblies feeding fuel and air to the furnace.

Abstract: Cartoning apparatus for packaging sealed bags containing loosely packed discrete articles in board cartons comprises a carton transfer and erecting mechanism which withdraws a collapsed carton sleeve from a magazine and deposits it in erected condition on a carton conveyor which advances the erected carton sleeve with step-by-step motion through a plurality of work stations. A form, fill and seal machine delivers a sealed bag containing a product to a vacuum conveyor which accelerates the bag through a guide shroud and into the near open end of an associated carton sleeve supported on the carton conveyor at a carton filling station. A rail disposed at the far open end of the associated carton sleeve arrests the bag within the sleeve. The carton conveyor advances the carton sleeve and bag to further work stations where the carton end flaps are closed and sealed.
