Abstract

854,577. Electric ovens. PHILIPS ELECTRICAL INDUSTRIES Ltd. March 13, 1959 [March 17, 1958], No. 8781/59. Class 39(3). An electric oven has a U-shaped electric heating element 5 and the articles 20 to be heated are passed into the heating zone between the limbs of the U by a rotary member 3, the supports 19 for the articles 20 extending through slots 10, 14 in the inner and outer enclosures 1, 2. The inner enclosure 1 is of quartz, internally polished, and the outer enclosure 2 is double walled for the circulation of cooling water. Argon is supplied to the interior of the oven through a duct 24.
