Les chaînes YELLOW et YELLOREX

[Ebykr summary; the article’s text is not reproduced. At the Salon du Cycle, bicycle and motorcycle dealers (Vélocistes et Motocistes) were particularly interested in the stand of the Compagnie des Transmissions Mécaniques Sedis. The stand gave an ingenious demonstration of the qualities of the Yellow and Yellorex chains by means of experimental devices in operation. First, the suppleness of the links was shown, together with their perfect straightness, by a sprocket and a chainwheel holding their place in a vertical plane on a chain turning at 2,000 revolutions a minute. Second, resistance to wear was proved by a device (the sentence continues in the next column).]

[A text-only passage in the magazine’s own column. The heading stands at the head in upright roman type with wide letter spacing, with the names YELLOW and YELLOREX in heavier capitals, and the line runs out to the right margin. Beneath it the running text is set in italic roman type, twelve lines in all, with the firm’s name in upright roman among the italics, Sedis in small capitals within it, and the chain names Yellow and Yellorex likewise in upright roman. The last line breaks off mid-sentence at the foot of the crop. No drawing, photograph, signature or agency mark appears in this part.]

[Ebykr summary, continuing the sentence from the previous column; the article’s text is not reproduced. The wear-resistance device made a chain turn under a pull of 100 kg for hundreds of hours. The notice adds that the stand also showed the fine Yellow challenge, which for more than 20 years has rewarded the effort of the country’s greatest champions.]

[A text-only opening of two italic lines, then a halftone photograph, centered in the column and wider than it is tall, without a ruled frame, showing a trade stand at an exhibition. A large pale panel at the center carries the word YELLOW in dark letters at upper left and a shaded oval ring with the name SEDIS drawn inside it, with YELLOREX in dark letters at lower right. A small sign above reads “SEDIS” in quotation marks, and other signs at the left and right edges carry further names, partly cut off by the frame and only partly readable. In the foreground a low table holds small objects and a small standing statuette, and white pedestals at the left and right each carry a vertical test rig with a looped chain. Below the photograph three lines of italic type follow, with the word Yellow in upright roman, and a single star of a three-star break mark shows at the foot of the crop. No caption, signature or agency mark appears.]
