摘要： The oven cooking cavity has a perforated top wall above which there is a substantially full width plenum chamber which receives from a rear exterior duct heated air and gases under pressure for discharge of the same downwardly through the cavity top substantially uniformly over the area of the same. The heated air and gases exit from the cavity at the bottom and comingle with newly heated air and gases from a bottom forward gas burner in passage therewith to motor-driven impeller means which discharges into the delivery duct. In such gas embodiment, a small portion of the circulation within the cavity is vented to the atmosphere at the top front of the oven and compensating make-up room air supplied. The heat source can also be electric, with full instead of substantially full recirculation as in the gas embodiment.

摘要： The gas burner and blower powered oven includes a mixing chamber of appreciable length that receives bottom outflow air from the oven and, in general opposition, an input from the burner which includes make-up room air. A substantial flame is produced in the chamber for combusting volatiles in the oven outflow and the latter is mixed in the chamber before proceeding to the inlet of the blower, the latter discharging the hot air into the oven through a multiplicity of holes in a top manifold for downward substantially uniform flow throughout the oven.

摘要： A slidable support system is formed of two rails having opposed channels. The rails have flat mounting surfaces adapted to be affixed to a support and an element to be slidably mounted, and at least two bearings are provided extending into the channels of both of the rails. The bearings have generally cruciform cross sections, and may be affixed to one of the respective rails, or free-floating with respect to both of the rails.
