Patent ES-8300036-A1 (ES)
Title: Method and means for removing the grinding dust from a grinding belt.
IPC: B24B55/08
Filed: 1981-11-11
Abstract: In this method and means the reciprocating grinding shoe is briefly lifted at certain time intervals from the surface of the profiled piece to be ground in such a way that an air cushion is built up between the profiled surface and the abrasive paper of the grinding shoe during lifting of the latter from the profiled surface, which air cushion is subsequently displaced abruptly and energetically out of the space between the workpiece and the grinding shoe during the renewed return movement of the grinding shoe in the direction of the profiled piece. The apparatus according to the invention has a lifting device, which is operatively connected to the reciprocating grinding shoe, and also a compressed-air source which is provided with feed lines and/or discharge nozzles for feeding compressed air between the surface of the profiled piece to be ground and the bottom surface of the grinding shoe accommodating the abrasive paper.

Title: Process and apparatus for measuring optical-fibre diameter.
IPC: G01B7/12
Filed: 1982-06-30
Abstract: An optical fiber, being drawn from a preform and wound upon a reel, passes between parallel plates of a capacitor connected in a measuring circuit which, from the capacitance variations due to changes in fiber diameter, controls a reel-driving motor to minimize these variations.

Title: Matrix conversion system for dynamically redefinable character sets in a video system.
IPC: H04N1/387
Filed: 1983-12-28
Abstract: A system for transcoding signals for a 12x10 dot matrix into signals for a 8x10 dot matrix uses a two phase conversion process. In the first phase, the pixels of each line are arranged in groups of three and in their natural order. Each group of three pixels is logically processed to obtain a group of two converted pixels. In the second phase, the configuration of the initial four pixel block which straddles the limit or interspace between two three-pixel groups are analyzed. Depending on the difference found during the analysis, the two pixels which are converted in the first phase are kept on either side of the limit, or are replaced by either the corresponding converted pixels of the former line or the pixels that are calculated in the second phase.
