Abstract: An apparatus adapted to mix in a mixing chamber within the apparatus a waterless paint concentrate maintained in a reservoir within the apparatus. The concentrate is stored in the reservoir in a concentration unsuitable for application to a paintable surface. The concentrate is mixed with water received into the mixing chamber under external waterline pressure forming a paint suitable for application to a paintable surface. The paint is then discharged from the apparatus through a spray nozzle. Mixing occurs in the apparatus concurrently with discharge through the nozzle as water flows through the apparatus. The apparatus as largely a container of waterless paint concentrate with a simple mix and discharge spray head attached is disposable after consumption of the concentrate without need for cleaning.

Abstract: A steam-jacketed kettle for cooking food includes a combustion chamber below the steam jacket. The combustion chamber is provided with an atmospheric gas burner for heating water in the steam jacket. The burner is disposed in an offset location at one side of the combustion chamber and a series of flue gas outlets are provided at the opposite side of the combustion chamber so that combustion gases tend to wash across the bottom wall of the steam jacket, for even heating. The flue gas outlets communicate with respective flue pipes that extend back through the steam jacket to a common flue gas collector, so that additional heat can be transferred from the gases in the flue pipes to the steam jacket.
