Abstract: A method for moving a stack of products by a robot. The robot has an articulated arm and at least one gripper disposed on the articulated arm for gripping the stack of products. The stack of products is turned, before being moved by the robot, with a pivoting device that is separate from the robot. The stack of products is turned about a horizontal axis and the stack of products, while out of the horizontal orientation, is aligned and/or straightened in one direction and/or straightened in two mutually orthogonal directions and/or vibrated and/or aerated and/or modified from a fanned-out stack of products to become an unfanned stack of products. The robot then takes the stack from the pivoting device and subsequently moves the stack.

Abstract: A method moves a stack of products by a robot. The robot has an articulated arm and at least one gripper disposed on the articulated arm to grip the stack of printed products and the stack of products selectively being turned. The method includes pivoting the stack of products through an effective angle ?1< >180° and subsequently pivoting the stack through an effective angle ?2=180°??1 or pivoting the stack back through an effective angle ?2=??1. This method of moving stacks of products is performed in an automated way and in particular of depositing them in a turned or unturned arrangement.

Abstract: The present invention provides an auditory test and compensation method for an audio system comprising an audio device coupled to an audio output means and a listener of the audio device. The method comprises the steps of: delivering a series of audio stimuli through the audio output means; capturing a listener's response to the audibility of the stimuli; calculating a compensation print from the frequency response; deriving a filter from the calculated compensation print with respect to the frequencies associated with the frequency response and applying the filter to an audio signal of the audio system.

Abstract: In a process for decontaminating radioactively polluted lubricant oil, (a) the lubricant oil to be decontaminated is mechanically filtered, (b) an acid solution of the salts of the elements, the radionuclides of which are to be removed, is added, and (c) a dose of a precipitating agent that cooperates with the elements, the radionuclides of which are to be removed, producing a salt of low solubility, is added, (d) the acid salt solution is intimately mixed with the lubricant oil after step (b), (e) the depositing aqueous phase is discharged after step (b), before step (c), (f) additional intimate mixing is carried out after the dosed admixture of step (c), and (g) finally the precipitation products are separated by centrifugation from the lubricant oil.
