Patent ES-484075-A1 (ES)
Title: Single needle selection device for flat knitting machines
IPC: D04B15/70
Filed: 1979-09-11
Abstract: In a flat knitting machine, each needle 7 in needle bed 1 is selected to knit by being pushed leftwards as shown Fig. 3 by movement of push-rod 8 when its foot 9, in a raised working position engages a cam groove 14 on a carriage traversing the machine. Each push-rod 8 is engaged by auxiliary push-rod 10 provided with feet 11 and 12 in bed 2. As the carriage passes, firstly a cam 15 thereon acts on foot 12 to depress push-rod 10 which lowers push-rod 8 and foot 9 to a lower working position below cam groove 14. Depression of push-rod 10 causes foot 11 to displace a pawl 17 axially rightwards against a spring. This pawl movement pivots the lever near to an electromagnet which, if energised, holds the lever to lock the displaced pawl 17 so it cannot prevent push- rod 10 rising under action of spring 23 when cam 15 has passed. Foot 9 is thus lifted to the raised working position to be moved leftward by cam groove 14. If the electromagnet is not energised, pawl 17 is returned by its spring leftwards to engage above foot 11 and so hold down push-rod 10. Thus foot 9 remains in the lower working position and is not moved by the cam groove 14.

Title: Method and apparatus for automatically spacing characters during composition.
IPC: G09G1/00
Filed: 1984-04-09
Abstract: In a computer implemented system for composing lines of text the spacing between each adjacent pair of characters is uniquely determined by processing, in accordance with a pregiven program, a number of digital "space" values related to the shapes of the facing sides of the involved characters. Starting with a uniform or near-uniform fundamental spacing between all adjacent pairs of characters the processing of the space values of a given pair of adjacent characters results in possible adjustments in this fundamental value to achieve a more aesthetically pleasing line of text. For each pair of adjacent characters the processing is a two-stage one with the first stage making an adjustment in the fundamental spacing if it is possible to overlap portions of the two characters and with the second stage making an adjustment which, aside from the possibility of overlapping, is dependent on the degree of openness or empty space present between the characters when fundamental spacing is used.
