An oven (20) includes an oven enclosure (24) having a conveyor (40) mounted therein for transporting food products through the oven. A plurality of ribbon burners (100) are mounted within the oven interior (32) adjacent the path of the conveyor to heat the interior of the oven. Heated gases generated by operation of the ribbon burners are received through inlet plenums (140) under operation of a circulation fan (146) and are discharged through discharge tubes (154) extending adjacent portions of the conveyor (40) remote from the locations of the ribbon burners (100). Exhaust gases are removed from the oven interior through discharge ports (180) by exhaust blower assemblies (184) which are operated to remove exhaust gases from the oven interior at a rate proportional to the flow rate of combustion air and gaseous fuel into the ribbon burners.

A sorting switch comprising a plurality of pallet support members mounted for movement around a course including an upper article sorting portion comprising spaced, parallel article conveying paths. Pallets are slidably supported on the pallet support members and have switch engaging members depending therefrom. Switching mechanisms are provided for selectively allowing each pallet to remain aligned with the article conveying path normal thereto or for diverting the pallet into alignment with the opposite article conveying path. The pallets are alternately arranged with each pallet that is normally aligned with one of the article sorting paths being followed by a pallet that is normally aligned with the other article sorting path, and vice versa.

Conveyor and sorting switch

A grouping system (10) includes parallel conveyor belts (28) for conveying the objects from an unloader system (14) to an oven-ready conveyor (24). A group end sensor (64) is moveable along the grouping system (14) between the conveyor belts (28). The sensor includes both forward and rearward sensors (128, 130) for sensing the proximity of pans at a predetermined separation in the direction of travel. The group end sensor moves longitudinally until the forward sensor senses an object representing the last stopped pan. The conveyor operates at full speed until the rearward sensor senses the following pan. The conveyor speed is then reduced so that the pan contact does not damage the dough.

Disclosed is an automatically variable transmission of the planetary type in which the planet gears of the main or power gear train are carried on a rotatable power cage but are not bounded by an internally toothed ring gear. The transmitted torque and speed (relative to input speed) are functions of the rate of rotation of the power cage. Power cage rotation is controlled by driving it through a second or control planetary gear train having a similar rotatable control cage, the source of power being the input shaft of the transmission. The speed ratio of the main gear train decreases from input to output, while that of the control gear train increases. In operation, the rotational speeds of the power cage and the control cage adjust automatically upon variations in load to values appropriate for delivery of the amount of torque required at the required speed.
