Abstract: A process for coding a set of access cards adapted to control an apparatus for opening, locking or releasing a processing device and for the ultimate determination of the validity of a card when it is presented in the apparatus, the coding being effected by the formation on the cards of at least one diffraction grating whose recognition is effected by projection of a luminous beam on the grating and analysis of the diffracted beams. The grating is formed by means of a machine having a kinematic drive which is intentionally irregularized to produce at least one deviation in the spacing of the lines of the grating which varies periodically with a determined period and maximum amplitude. The modified grating will produce a supplementary satellite diffraction beam when illuminated by the luminous beam and whose angular position and intensity is measured to establish the validity of the grating.

Abstract: A new method of purification of human prostatic acid phosphatase has been provided. The starting point for the purification process is constituted by a solution containing acid phosphatase and having its origin in a sample derived from a human body. If required, said sample is subjected to a pretreatment so as to draw the phosphatase into solution and to remove any solid tissues. The solution is then treated by means of affinity chromatography, whereby the phosphatase in question is separated from other proteins. The chromatographic step is performed in a column packed with an agarose gel coupled with tartrate groups. A sodium acetate buffer containing tartrate may be used as an eluent and the eluate is collected as successive fractions. Those fractions containing the phosphatase are further treated by means of isoelectric focusing so as to separate the different isoenzymes of the phosphatase from each other. The isoelectric focusing may be performed either in a column or on a disc covered with a gel.
