An oven for cooking with light having wavelengths in the visible, near visible, and infra-red spectral ranges uses one or more quartz halogen tungsten lamps or quartz arc bulbs positioned above and below the food item. Uniform cooking of the food item is achieved by positioning the lamps asymmetrically with respect to the midline of the oven and by rotating the food item on a rack during the cooking cycle.

Apparatus and method for uniformly cooking food with asymmetrically

An apparatus for automatically handling food cooked in an oven comprises a tray which is positioned inside an oven and which is automatically slidable into a position in which it extends partially out of the oven. During its outward travel, the tray pushes against an oven door to open the door. The tray has an automatic pulley assembly which, when the tray is positioned inside the oven, engages with a motor assembly located in the oven. When the pulley assembly and motor assembly are engaged, the pulley assembly rotates a grill positioned on the tray.

Apparatus is provided for beveling or rounding the edge of thin, disc-like workpieces, such as silicon wafers integrated circuit masks and the like and includes a rotatable holder for receiving and releasably holding such a workpiece and rotating the workpiece with its edge free of obstruction. A rotating grinding wheel axially parallel to the workpiece and holder and having a V-shaped circumferential groove is urged against the edge of the workpiece by resilient biasing means so that the grinding wheel will be maintained in grinding engagement with the workpiece edge during the rotation of the workpiece.
