Abstract: A recirculating carbonator and beverage dispenser requires only one pump. The system's function can be enhanced by the use of a two position spool valve having a fresh water inlet port, a carbonated water inlet port, and a fluid outlet port commonly connected with a central bore. A spool member is slidably disposed within the bore to selectively interrupt fluid communication between the carbonated water inlet port and the liquid outlet port during the presence of a low water signal generated by a level sensing device within the system's carbonation tank. During the interruption, fresh make-up water is added to the system.

Abstract: Improved gas burner type apparatus for toasting bread-like articles is disclosed. The apparatus includes a housing providing a chamber including a toasting zone through which articles are carried by conveyor means. The toasting zone includes a pair of gas burners between which the articles are conveyed, and gas flow through the burners is controlled to provide, selectively, for toasting one or both sides of the articles.
