Abstract: The invention pertains to a process for modifying gypsum, wherein a continuous feed of raw gypsum is provided; the water content of the raw gypsum is determined in the continuous feed by near infrared spectroscopy (NIR) measurement; the raw gypsum is calcined in a calcination unit at a fire rate to remove water from the raw gypsum and to obtain a continuous feed of calcined gypsum having a water content within a selected range; a water content of the calcined gypsum is determined by near infrared spectroscopy, and the fire rate is adjusted based on the water content of the raw gypsum and of the calcined gypsum. Further, the invention pertains to an apparatus for performing said process.

Abstract: The invention relates to a set of mechanical means specifically designed to be incorporated into a delta robot, forming a machine that can gum lids at a much greater speed than those traditionally used and with substantially greater efficiency. In some cases, the machine is defined by a pair of arms, the ends of which includes a rectangular machined zone housing a stop element that provides a connection with a bolt. In some cases, the bearings are inserted on both sides of the machined zone by means of a bore-hole characterised in that it extends from the inner portion outwards, such that the hole is not a through-hole along its entire length and the bearings abut against the outer wall of the arm.
