1,186,252. Typewriters; selective printers. AMERICAN CYANAMID CO. 1 Feb., 1967 [9 Feb., 1966 (5); 14 Oct., 1966], No. 47107/69. Divided out of 1,186,251 Heading B6F. [Also in Division C4] A typewriter or selective printer is provided with type bars or type carriers which encode a selected alpha-numeric character in a binary code, the bits of which are impressed in different photo-luminescent inks, which for retrieval of the printed character are exposed to irradiation with u.v. light. Type bar machines; types and printing surfaces; inking pads; electric input signals.-A typewriter is provided in addition to its usual type bars (not shown) with coded type bars 110b, Fig. 4, including a head 110a, having a number of projections 112, 114 arranged in a binary combination and co-operating with a respective ink ribbon band (101 . . . 106, Fig. 2) impregnated with different photo-luminescent ink. In another embodiment the coded type bars may be replaced by a reciprocated hammer 312, Fig. 10, actuated by output signals from a decoding matrix and co-operating with a rotary disc 304 sub-divided into six segments (305 . . . 310, Fig. 11) each of which is impregnated with a different photo-luminescent ink. In a further embodiment an adding machine is modified in that the type bars 70 . . . 74, Fig. 8, are provided with spring biased slugs 1 . . . 10 associated with anvils 2211 and impelled by hammers 2221 into contact with a record medium 79 to impress the selected numeric character in a respective photo-luminescent ink contained in an inking pad 75 sub-divided into a number of different reservoirs by partitions 76 of plastics material or metal to prevent intermingling of the different photo-luminescent inks. Matrix printing heads; electric input signals; dies and printing surfaces; inking arrangements.-The code type bars 110b, Fig. 4, may be replaced by a matrix head 424, Fig. 14, comprising six rods 431 . . . 436, Fig. 13, arranged in two vertical columns and actuated by a decoding matrix 426 whose output signals are applied to transducers 437 the cores 441, 443 displace the rods 431 . . . 436 into contact with a record medium (420, Fig. 12). The rods are porous and ink with different photo-luminescent inks from associated reservoirs 428. In a modification the matrix head may have four rods (572 . . . 575, Fig. 15) extending in the letter spacing direction and co-operating with respective ink-ribbons (582 . . . 585) or extending in the line spacing direction (Fig. 17) and co-operating with an ink ribbon having four bands each of which is impregnated with a different photo-luminescent ink.
