Title: Improvements in or relating to typesetting apparatus
IPC: B41B25/00
Filed: 1961-06-30
Abstract: 998,714. Strip-perforating machines; justifying type. HARRIS-INTERTYPE CORPORATION. June 30, 1961 [June 30, 1960], No. 23755/61. Heading B6W. A set indicator for typesetting apparatus comprises means for providing a first signal related in magnitude to the actual space occupied by characters in a line of predetermined length, means for providing a second signal related in magnitude to the number of interword spaces in the line, means for converting said second signal into another signal which is a function of said second signal and the point set, comparing means for receiving said first signal and said other signal and operative to determine the adjustment in length of each interword space required to justify the line, and means controlled from said comparing means for providing a visual indication of unused space in the line as the total space used approaches the available space in the line. In a strip-perforator unit of a phototypesetting apparatus, as described in Specification 989,626, the last nine stages of the line length counter actuate set indicator relays which control contacts from a line 170, Fig. 2, through resistors 161 to a meter 150. The word space counter actuates relays which control contacts from a line 188 through resistors 181 to the meter, there being also in the circuit a variable voltage supply control 195 settable to a predetermined word space width, and a potentiometer 192 for selecting the point size. The two currents flow in opposite directions, and there is also a biasing current through a resistor 173. When the meter reads zero, the line will be justified with spaces of the predetermined width. In another form, Fig. 5, stages of the line length counter LC actuate relays 225 which control the secondary windings of a transformer 235, producing a voltage on line 238 representative of unit width, which is transformed by a multi-tapped auto-transformer 240 into a voltage on line 248 representationof actual width. The stages of the word space counter actuate relays 260 which control the secondary windings of a transformer 267, producing a voltage on line 268 representative of the number of word spaces, which is converted by a space width potentiometer 270 into a voltage on line 273 representative of the number and width of the spaces. The voltage difference between the lines 248 and 273 is indicated on a voltmeter 275, representing the remainder not used for characters. A potentiometer 280 is driven by a reversible motor 284, and the voltage difference between the line 248 and the tap 282 of the potentiometer is applied to the primary windings of a transformer 287, the secondary windings of which are connected to a zero and phase-directing circuit 290, which controls the motor 284, the potentiometer 280 providing on a scale 300 a visible indication as composition of a line proceeds. Specification 998,716 also is referred to.
