Abstract
1423934 Slide rule with electronic calculator A W FABER-CASTELL 8 April 1974 [10 April 1973] 15552/74 Headings G4B and G4A A slide rule that includes an electronic digital calculator 3 comprises a stock 1 having a slide 2 and scales (13) on its front side (not shown) and the keys 6 and 12 of the calculator projecting from its reverse side, Fig. 1. Strips 15 on the edges 4 and 5 (possibly integral with them) form a support to prevent the keys being depressed when the rule is placed on a surface. The calculator 3 is preferably mounted on a plate 19 that is held in the stock by tongues 18 and grooves 17 so that it may be slid out, e.g. to change batteries. The electronic components all lie within the cavity 14 of the stock, only the keys protruding from the plate; these components may be encapsulated in plastics material to form a slide the size of the cavity 14. Visual displays 11 (and 16, Fig. 3, not shown) indicate the computer output on both sides of the rule.
