Abstract: A security gate actuator includes a main ball screw, a main ball nut, and a drive shaft stage. The main ball screw may further include a circular channel disposed on an outer surface of the main ball screw and at least one drive ball disposed in the circular channel. The main ball nut may be disposed on the main threads of the main ball screw and configured to translate rotational motion of the main ball screw to linear motion of the main ball nut. The drive shaft stage may include a drive shaft end and a drive shaft tube attached to the drive shaft end, the drive shaft end coupled to the main ball nut. The drive ball may push against the drive shaft tube to translate the rotational motion of the main ball screw to rotational motion of the drive shaft tube.

Abstract: A method and materials for screen printing a substrate with raised designs. The raised designs allow for a lenticular effect through the printing of substantially parallel lines with varying heights in differing portions of the lines. The lenticular effects achieved include anticounterfeiting markings in bar codes and in the appearance of different colored images depending on the angle of view.

Abstract: Phenyl trichloro-ethanes can be prepared by reacting chloral with a phenol compound, such as phenol itself or 2,6-xylenol in HF, which acts both as a catalyst and solvent medium.
