Abstract: An improvement to conventional atmospheric gas burners particularly advantageously applied to the type used as surface heating units in gas cooking appliances such as ranges and cooktops, which typically comprise a burner head having a plurality of primary burner ports formed at port locations equally spaced about the periphery of the burner head. Improvement is realized by not forming primary burner ports at selected ones of the equally spaced port locations. The unused port locations are selected so as to separate the primary ports into groups. The reduction in the number of ports reduces the total port area thereby reducing the amount of primary air entrained in the air/gas mixture delivered to the burner. In addition the resulting spacing of the groups of ports has the effect of reducing the amount of secondary air per port relative to that which would be entrained by the same number of ports, if equally distributed about the periphery.

Abstract: A process for heating fluids to a relatively high temperature, such as sterilization temperature, in which the fluid, such as a liquid, is heated by direct contact with steam while it is in the form of a very thin, free-falling film or a continuous falling stream so that heating of the fluid is accomplished without the fluid coming into contact with any surface and particularly metal surfaces which are hotter than the fluid product being heated and with minimum agitation and turbulence of the fluid product. This procedure enables maximum and uniform heat penetration in a minimum time interval with the film or stream being maintained as thin as possible and unbroken by introducing steam at a relatively low velocity in a large volume vessel.
