Abstract: An apparatus and method for removing contents from an envelope are disclosed. In the apparatus a front envelope wall is severed from a rear envelope wall along three of the folding edges, the envelope is separated from its contents and finally the separated envelope is removed along an exit track (6). The exit track passes along the outer side of the apparatus and is at least in part externally visible. The envelope is transferred to said exit track in an unfolded condition and transported along the exit track with its former inner surfaces of the envelope walls turned away from the apparatus. The invention provides a possibility to check visually in a simple and efficient manner whether the contents of an envelope have been removed completely.

Abstract: In a process for the hydrodynamic drawing of a synthetic monofilament or multifilament yarn, the yarn, if it is a multifilament yarn, is made into a ribbon and pulled through a brake fluid. Within the brake fluid, the yarn is heated to a temperature which corresponds to the glass transition point of the filament material and braked in such a way that the yarn tension at one point in the brake fluid corresponds to the drawing tension which is necessary to draw the filament or filaments. To be able to match process and apparatus to various materials and to various yarn speeds and to optimise process and apparatus in respect of the quality of the drawn product, the braking effect of the drawing arrangement is set and/or controlled via the length of travel of the ribbon in the brake fluid, the viscosity of the brake fluid, additional mechanical braking and/or the flow ratios in the drawing arrangement. The apparatus consists of a quasi-sealed main chamber (1) within which a brake fluid is circulated. The brake fluid also acts as a heat transfer medium. The main chamber (1) can have a prechamber (7) with a variable liquid level (14). The chambers are formed by two mutually fold-back parts, so that there is no problem with introducing the yarn. …<IMAGE>…

Abstract: According to the invention, the actual position of a servo head is calculated by converting servo signals (PosN, PosQ) read out from a servo head (31) to digital signals every predetermined time and by making a digital operation circuit (50) operate on the basis of converted digital values. The method of calculating a predicted position of a servo head which is necessary for calculating the actual position of the servo head, is charaterized in that the moving speed of the servo head is calculated from the previous position and the current one, and a predicted next position of the servo head is calculated from the calculated moving speed and the time interval until the next time of calculating. Also, this invention is characterized in that when the actual position of the servo head calculated from its predicted position and the digital-converted servo signals is largely different from the predicted position used as the calculating basis, noise in the servo signals is considered as the cause and the predicted position is assumed to be the actual position leaving as it is, without using the calculated values as the actual position. Further, this invention is characterized in that the period of the servo signal read out from the servo head is measured in a state in which the servo head is moved at a predetermined speed by feeding a predetermined driving current to a motor after the power supply for driving a disc is switched on, and that the moving speed of the servo head is calculated from the measured period and the known distance corresponding to the period of the servo signal.
