499. Electropolishing techniques for the preparation of zirconium and Zircalogy-2 specimens for transmission electron microscopy
Classified Abstracts 496--505 working with the discharge current density in the abnormal glow region. The tube can be run equally on d.c. or on unsmoothed, half-wave-rectified a.c. M.D.A. N. McLoughlin, D. Reaney and A. W. Turner, Electronic Engng, 32 (385), March 1960, 140-143. 31 : 18 A continuously operating laser.

36 501. Accelerated freeze-drying of foodstuffs. Australia. A survey is made of the historical developments in freeze-drying up to the time when the " accelerated freezedrying " technique became fully developed. The principles involved in this technique, and others, are shown to depend particularly on the method of heating. The freeze-drying plants that have been designed and constructed for carrying it out are discussed together with certain aspects pertaining to the properties and costs of freeze-dried foods. (Author) J. D. Mellor, FoodPres. Quart., 22, 1962, 41.
36 502. Engineering aspects of freeze-drying foods. Australia. A lecture, beginning on a historical note, which briefly surveys the development of freeze-drying over a period of twenty years to preserve biological products, and in recent years to prepare special food products. Methods of heating and removing water in freeze-drying, and the equipment and controls that are necessary in order to achieve this, are explained. Also the storage of freeze-dried foods, and the capital and operating costs of freeze-drying plants are discussed. (Author) J. D. Mellor, Refrig. J., 15, April 1962, 38 and 15, May 1962, 38.
