Abstract: An electrical measuring system of a six-port circuit includes a delay line and a arithmetic unit. In a first operating mode, an electrical signal can be on the one hand transmitted directly to a first input terminal and on the other hand via the delay line to a second input terminal of the six-port circuit. In an embodiment, the measuring system is configured such that, in the second operating mode, it does not supply a signal to the first input terminal of the six-port circuit and it supplies a reference signal to the second input terminal of the six-port circuit.

The latter (11) has a laminated structure (2) and a shape (30) such that power supply is not needed to cause a modification of magnetization in the sensor element (11) when the magnetic field passes in front thereof, and in that several such modifications can be stored.

Abstract: In the pneumatic pressing of textile strands in a drafting frame the pressure in the pressure line is monitored by a pressure sensor and/or a flowmeter and used to control a value between the pressure source and that pressure line. According to the invention a disturbance signal is outputted when the pressure in the line drops below a threshold, the control signal for the valve exceeds a threshold, the displacement of the value member exceeds a certain level and the flow rate exceeds a value so as to indicate leakage beyond a tolerance level.

Abstract: A spinning- or twisting-machine has an elongated spindle bank, a row of rotatable spindles supported on the bank, respective individual drive motors on the bank for each spindle, respective electrical control circuits connected to the respective motors and electrically energizable to power the respective motor, and a plurality of electricity-supply conductors extending along the bank past the spindles. A respective housing support part for each spindle carries the respective electrical control circuit and is provided with electrical-input contacts. A mount engaged between the housing part and the spindle bank allows movement of the housing part on the bank between a closed position in which it surrounds and protects the respective circuit and in which the contacts conductively engage the supply conductors and an open position in which it exposes the respective circuit and disengages the contacts from the supply conductors.

Abstract: An arrangement for mounting a suction tube on a fly frame, roving frame, ring spinning machine or the like for collecting broken ends of yarn at the outlet rollers of the machine. The suction tube has a suction end and an opposite end connected through a flexible sealing sleeve to a collection chamber, with the sleeve permitting the suction tube to pivot between different positions. A mounting rod is secured to and extends between the stanchions of the machine frame intermediate the collection chamber and the outlet rollers, and a support arrangement is mounted on the rod and includes a retaining mechanism for positioning the suction tube and releasably retaining it in an operative position in which the suction end is proximal the outlet rollers and an inoperative position in which the suction end is spaced from the outlet rollers. In one embodiment the suction tube is pivotally mounted on one arm of the support and releasably retained in a slot in another arm of the support.

Abstract: In the process and apparatus for loading a ring spinning machine with roving-supply bobbins at least two bobbins rows extending longitudinally on each side of the spinning machine supply roving to the work stations and a auxiliary bobbin row which can travel in with full bobbons and out with empty bobbins are provided. According to our invention an exchange process is provided comprising replacing the roving of the bobbins in one of the bobbins rows supplying the roving which is being consumed by the roving of the auxiliary bobbin row which has been brought in with full bobbins. Thus the auxiliary bobbin row becomes one of the bobbin rows dispensing the roving while the bobbin row being replaced now becomes the auxiliary bobbin row with empty bobbins and is taken away. A new auxiliary bobbin row with full bobbins is then brought in. The exchange process is repeated for each of the bobbin rows as the roving is exhausted. A simple space saving apparatus for performing this process is described.

Abstract: A suction tube for a fly frame, roving frame, ring spinning machine or the like for collecting broken ends of yarn at the outlet rollers of the machine. The suction tube is connected to a collection chamber through a flexible sealing sleeve that permits the suction tube to pivot between its operative and inoperative positions. The suction tube comprises a suction end disposed under the bottom roller of the outlet rollers that has a body portion formed with a suction opening therein, an opposite end connected to the flexible sealing sleeve, and a pair of side walls projecting upwardly from the suction end body portion toward the bottom roller and longitudinally beyond the suction opening on opposite sides of the yarn for confining the suction substantially to the bottom roller and the yarn path.

Abstract: The invention relates to a tangential belt drive for a plurality of similar work units of a machine for the production of twisted or twined yarn. These units are subdivided into sections each having at least approximately the same number of work units and each driven through a tangential belt by an electric motor. Thereby, the number of work units in each section is established taking into account the required power and permissible belt stretch, so that the tangential belts have a considerably reduced width and thickness, compared to the ones commonly used. Further, the guide rollers of the tangential belts of neighboring sections are corotationally connected to each other.In order to improve synchronization and power transmission between sections, the contact angle is increased at the guide rollers and the drive pulleys. This may be done through the corresponding spatial arrangement of the drive pulleys with respect to the guide rollers or through use of an intermediate belt arrangement.

Abstract: A coupler includes a transducer and an optical waveguide ending in front of the transducer, the fiber end of the optical waveguide is soldered into a guide sleeve by using a high-melting solder. To safeguard a sufficient adjusting clearance for the transverse displacements necessary for effecting the coupling, the guide sleeve in the wall of the housing of the encapsulated arrangement, passes through a borehole of larger diameter. This borehole is closed by a coverplate traversed as well by the guide sleeve, with this coverplate being connected to the guide sleeve and, simultaneously, to the housing by way of soldering and by the use of a low-melting solder. Due to the fact that the forces resulting during the cooling of the solder, act ring-symmetrically upon the guide sleeve, maladjusting transverse displacement vis-a-vis a previously adjusted position of the fiber end with respect to the transducer is prevented.

Abstract: A textile machine filter has its filter surface divided into zones which can be independently wiped by a stripper movable into juxtaposition with the zones or by respective strippers assigned to each one. A common collection space is provided beneath the filter surface to receive the contaminants from each zone.

Abstract: The invention relates to a tangential-belt drive for a plurality of work units of the same kind, arranged at least in one row next to each other, of a machine for the production of twisted or twined yarns. The work units are divided into sections with at least approximately the same number of work units, each driven with an endless tangential belt. At least one electromotor is assigned to each section for driving the thereto pertaining tangential belt and guiding means for the tangential belt.In order to reduce the energy losses of such a tangential-belt drive, the width and thickness of the tangential belt used is considerably reduced, particularly to a width between 7 and 14 mm and a thickness between 2 and 2.7 mm. Size reduction becomes possible because the number of working units in each section is selected by considering the working capacity required by this number of work units and the acceptable belt stretch factor.
