1,144,081. Photographic type-composing; strip-perforating. HARRIS-INTERTYPE CORP. 11 March, 1966 [12 April, 1965], No. 10892/66. Heading B6W. Strip-perforating; justifying type.-The keyboard machine is of the general construction described in Specifications 998,714 and 1,075,782 but contains the following additional mechanism. A dial (40, Fig. 1) controls a switch (333, Fig. 9B) to insert a " point size change " signal in the tape, and to set a selector switch (325) to insert a signal indicating the new point size. A lever (42) controls switches (350, 351, 360, 361) to insert a signal for selecting one of two matrix discs in the photographic machine and to select one of two fonts on the selected disc. An end-of-line-code, which may be " accept line " (carriage return key), " reject line " (reject key on auxiliary keyboard), or " non-justify " (key on auxiliary keyboard). These signals control a stepping switch (428, Fig. 14). If the line contains less than ten code units, a stepping switch (400) acts to insert " skip tape codes to make up a desired minimum length between end-of-line signals. The circuit illustrated in Fig. 14 then controls the insertion of five more signals, namely (1) fractions of points, if any, in desired line spacing, under control of a printed circuit switch (445, Fig. 1), (2) full points in line spacing, under control of a second printed circuit switch (455), (3) number of interword spaces to be justified, under control of a counter (125, Fig. 5), (4) piclets available for justifying, under control of the stages LC1-LC32 of a second counter (118), and (5) pieces available for justifying, under control of the stages LC64-LC2048 of the second counter (118). Three " skip tape " signals are then inserted to leave a length of tape available for spacing. Record tape.-The tape, Fig. 4, perforated by the keyboard machine, comprises eight code channels (a-h), channel (h) having a perforation in the case of function signals and not in the case of character signals. The end-of-line code comprises nine code signals, namely, the " end-of-line " signals, the five more signals referred to above, and the three " skip tape " signals. Photographic type-composing.-The general construction of the composing-machine is is disclosed in Specifications 912,202, 998,771, 1,008,146 and 1,073,088, but additional mechanism in disclosed. The space computer (725, Fig. 15) is shown in detail in Fig. 36. An energy absorbing brake is provided in the stepping motor dr
