Abstract: In the case of a transformer-supplied valve converter, a series circuit having a capacitor (4) and an inductor (5) which can be bridged is connected across the secondary winding (3) in order to use the method. The main valves (12, 13, 14, 15) are activated in each half-cycle of the supply voltage by phase-controlled control pulses, the control voltages being applied alternately to the valves at a time interval which corresponds to one half-cycle of the charging current of the capacitor (4). In the second half of the half-cycle of the supply voltage, the control pulses are also applied to the damping valves (20, 21) alternately, at a time interval corresponding to the half-cycle of the capacitor charging current. The method can be used for current transformers in the electrical industry, for supplying various DC and AC loads, especially for railways. The method allows a power factor of more than 0.95 to be achieved, the inductive voltage losses to be reduced and the interference effect of the railway power supply to be reduced. <IMAGE>

Abstract: For the purpose of carrying out an MMV-treatment (Mandatory Minute Volume) by means of a lung ventilator which includes a breathing-gas source from which a patient connected to the ventilator is able to breath spontaneously through an inspiratory line, and a ventilator unit which can be activated by means of a control signal so as to deliver to the patient through the inspiratory line a mandatory breath of determinable tidal volume from the breathing-gas source, the flow of breathing gas through the inspiratory line is continuously sensed by means of a flow meter. In a control unit there is generated a signal which is representative of the continuous integral of the difference between a reference signal and the flow signal from the flow meter. The value of the integrated difference signal is compared with a given limit value. Each time the value of the integrated difference signal reaches the limit value, the ventilator unit is activated to deliver to the patient a mandatory breath of given tidal volume. Alternatively, the ventilator unit may be arranged to deliver to the patient mandatory breaths of a constant given frequency and of a tidal volume, whose magnitude is determined with each mandatory breath, by the difference prevailing between the value of the integrated difference signal and the limit value.

Abstract: A large, e.g. oil-cooled, power transformer is assembled from at least two separately transportable units each comprising a magnetic circuit and associated transformer coils enclosed within a sealed tank. Parts of the magnetic circuit of each unit protrude from the associated tank via respective seals so that the protruding magnetic circuit parts of the two units can be releasably coupled together to provide a magnetic coupling between the two units. The invention has particular application to transformers which, due to their size and weight, would be impracticable to transport fully assembled. The self-contained transformer units of the invention can each be made of a conveniently transportable size for assembly at a user site into a larger multi-unit transformer while obviating the need to expose the working components of the transformer to the deleterious effects of draining and refilling the tanks with cooling oil as in existing systems. <IMAGE>

Abstract: The invention relates to a process and a device for the automated control of clothes from a laying-out table to a sewing machine for sewing on zip fasteners. The aim is to guide the garments and the zip fasteners to the sewing machine automatically in order to dispense with their manual introduction and guidance and so eliminate the stretching of the material. To achieve this, the edges 13 of the garment 11 along which the zip fastener is to be attached are placed next to each other essentially horizontally in an edge-to-edge arrangement. A gripping device 21 holds the garment along these edges a little further in the garment and essentially parallel to the edges, and it turns the garment in the vertically suspended position. The lateral parts of the garment 11 that are adjacent to the top and bottom gripping devices are separated from each other by a separating device 28 to assume a position essentially parallel to the grip rails 27 of the gripping device. The gripping device 21 and/or the separate pressing rails 37 press the edges 13 of the garment 11 against a transport device 23, which delivers the garment to a sewing machine 34. A zip fastener is introduced from above to a position in contact with the edges 13 of the garment. These edges, with the zip fastener over them, are taken to a position under the cloth presser 40 of the sewing machine for sewing the zip on. <IMAGE>

Abstract: A device for detecting metallic objects in a material flow, comprising as sensing member a scanning coil consisting of a primary coil and, for example, two oppositely connected secondary windings arranged symmetrically around the primary winding so that the voltage induced in the secondary winding becomes zero as long as no conducting objects appear in the scanning area. To eliminate irrelevant signals from conducting objects in the vicinity of the scanning coil but not in the material flow or from weakly conducting objects in the material flow, the primary winding is fed with at least two alternating currents having different frequencies. The corresponding secondary voltages are rectified in phase-controlled rectifiers, and in a calculating circuit the difference is derived between the output of one rectifier voltage and the output of another rectifier multiplied by a constant factor which includes the relation between the frequencies of the corresponding alternating voltages.
