Abstract: An automatic cooking machine includes a feeding device, a deep-fry device, stove device, a cooker transmission device, a serving device, a washing device, a stir-fry device and a panel each mounted on a base. A program logic controller corresponding with micro-switches and photoelectric sensors controls each of the devices to carry out an automatic cooking process. With such an automatic cooking machine design, the automatic cooking machine can stir-fry and deep-fry like a human cook and is easy to keep in good repair.

Abstract: An accessory (10) for a wrench socket (12) is disclosed including a generally cylindrical magnet (32) secured to a generally cylindrical, nonmagnetic, compressible disk (26) which snugly fits within the well (14) and magnetically insulates the magnet (32) from the socket (12). Specifically, the magnet (32) is received in a frustoconical recess (46) formed in the disk (26) while its temperature is elevated allowing the disk material to flex and stretch during the insertion of the magnet (32) into the recess (46). The magnet (32) is nickel-plated (43) and its corners are beveled (41) for ease of insertion of the magnet (32) into the recess (46). Air is received within a pocket (51) extending from the recess (46) and/or vented to the atmosphere through a vent hole (53) as the magnet (32) is forced into the recess (46).
