    摘要： A quantitative ion exchange process for preparing modified clay is disclosed. Clay such as montmorillonite is converted (1) to an acid-free hydrogen-clay by use of an anion (hydroxide) exchange resin; or (2) to another cationic form such as lithium-clay by use of an anion (hydroxide) exchange resin and an equivalent amount of the exchanging cation.

    摘要： There is provided a method for the determination of the fertile and infertile periods in the monthly cycle of females, and a device for carrying out the measurements and evaluations of this method. The method is based on the measurement of changes of characteristics of the cervical mucus and of polarization impedance. Furthermore, additional auxiliary information can be obtained by daily temperature measurements. A device is provided for effecting the required measurements, and for the evaluation of these.
