Abstract

1,217,111. Magnetic printing. CREED & CO. Ltd. 17 April, 1969, No. 19604/69. Heading B6C. Magnetizable powder 4, of the kind used to develope magnetic images for display or for printing purposes, is transported along channel 1, which is of non-magnetic material, by passage of permanent magnets 5 along the exterior surface of channel 1. A magnetic image may be made by selective magnetization of a magnetizable surface, such as the surface of a drum or belt, and the image is developed by dusting with the powder 4. The powder image so produced may be displayed directly, or may be transferred, e.g. to a paper tape or sheet.
