Abstract

399,654. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd., Blyth Road, Hayes, Middlesex, and WRIGHT, W. D., 69, Lakeside Road, Palmer's Green, London. Oct. 12, 1932, No. 28489. [Class 40 (iii).] Analysis or synthesis is carried out on an oblique section 3 of the solid angle swept out by the scanning-rays, and a rectangular object is so projected on the section that it fits the section, or a rectangular image is obtained from the section. The object 1 to be transmitted and the photo-electric plate 4, on which it is projected, are oblique to the axis, of the projecting-lens 2. When a large three-dimensional object 19 is to be transmitted, a reduced real image 18 is first formed, and then projected on the photo-electric plate by an obliquely inclined lens 2. At the receiver similar projecting arrangements are used to obtain a rectangular image from the image which is reconstituted on the inclined fluorescent screen 4 in the form of a regular trapezium.
