Abstract: Recesses (14) for accommodating in each case a cutting-body carrier (16) are distributed at equal angular distances over the periphery of a disc-shaped body of a milling cutter. Each cutting-body carrier (16) is designed in an L-shape having a radial arm (18), which is accommodated in a radial part of the recess (14) allocated to it, and an axial arm (20) which is arranged in an axial part, open to the outside, of the recess (14) and is fastened to the cutting body (22). The radial arm (18) has a main contact surface (34) facing the body (10) of the milling cutter, and the recess (14) has a corresponding mating contact surface (36). A shim (38) of defined thickness can be inserted between the main contact surface (34) and the contact surface (36) opposite it in order to set the width of cut of the milling tool. <IMAGE>

Abstract: A regulated switched-mode power supply with high-voltage generator for a television receiver presents particular problems with respect to the suppression of interfering resonances of the high-voltage winding, to the stabilisation of the critical secondary voltages and to the efficiency. Due to the combination of features according to the invention, the interfering resonant oscillation is suppressed by means of an auxiliary winding, the critical secondary voltages are stabilised by special coupling ratios between the primary and secondary windings and the eddy-current losses are avoided by dividing the air gap into several individual air gaps. The switched-mode power supply according to the invention is particularly suitable for television sets in which the switched-mode power supply operates at a frequency independent of the line frequency and, in addition to the low-voltage operating voltages, also generates the high voltage. <IMAGE>

Abstract: A method and apparatus is disclosed for measuring the tension of an advancing yarn which is subject to interrup­tions of the yarn path, resulting for example from the severance of the yarn. During such interruptions, the zero setting of the tension sensor does not always return to zero, thereby providing an erroneous output reading during subsequent yarn advancing cycles. In accordance with the present invention, a circuit is provided which identifies such errors and sounds an alarm when the error exceeds a predetermined limit. Also, the erroneous output signal is input as the zero point signal for the subsequent yarn advancing cycle, and during such subsequent cycle, the tension is determined on the basis of the newly set zero point.

Abstract: 1. Process for the batch preparation of thermoplastic, high-molecular-weight copolyesters. 2.1 Whereas it is known in the preparation of poly-1,4-butylene terephthalate to reuse the distillate produced during the polycondensation, this measure is unknown in the preparation of copolyesters. There is therefore a need to also use this resource-protecting and economical measure in the preparation of copolyesters. 2.2 The invention describes a process for the preparation of thermoplastic, high-molecular-weight copolyesters by transesterification, esterification and polycondensation of the starting components in the presence of a catalyst in the melt in the absence of oxygen, with 5 to 30 % by weight of the pure diol component being replaced by the diol (mixture) produced in the polycondensation, and the unpretreated distillate containing the diol (mixture) being recycled into the esterification.
