(¿negocios en alemán?),
There were some mistakes and printer?s errors in the tables in the Yellow Book,and certain explanations were called for. The patent numbers in Table 1 were for methods of construction, such as metalstrips in slides, and not for design of scales etc. There was a big family of ?Disponent? SR: 1/22 for 10?; 4/22 for 20?,51/52 for the ?Scholar? types of the mid30?s, and then X/60 for short pocket types. Full production was resumed by 1948,and included the fully plastic 10? rule. The suffix ?a? indicated the hybrid presence of the Addiator on the back of the rule.The third family of Merchant rules was the Bivius, 1/27 and 1/28, not as successful as the Disponent. The 1/22 and 3/22had the ?upright? metal inserts of the first Faber-Castell SR Patent. 90/22 and 90/28 were Scholar types, a critical patentcoming in 1928, and the Bivius after the 1/27 had 2 LL scales. The 1/27 was a blend of the Rietz and the Disponent, theLL scales being on the reverse and in the 1/22/3 the interrupted £sd scale was converted to a single scale. Later there hadbeen shortening of the LL scales and addition and subtraction of ?ladderlines?.
..., pero sigo con la pregunta: ¿"Bibius" es "Disponent" en alemán?
