  • Patent number: 11929641
    Abstract: A segment core and an axial flux motor. The segment core is formed by covering an SMC core (100, 100?) over an outer peripheral surface of a laminated core (200, 200?). An outer surface of the segment core, which can not be processed easily, is shaped by processing the easily shapeable SMC core (100, 100?). The entire structure of the laminated core (200, 200?) is relatively simple, and thus a mold for processing the laminated core (200, 200?) requires simpler specifications. Moreover, the mold can be used to perform processing easily, thereby reducing difficulties of processing the segment core. The segment core has better electromagnetic performance than a segment core solely using an SMC material, and has a higher core utilization rate than a segment core solely using a laminated core (200, 200?).

  • Patent number: 11835617
    Abstract: A method for determining an operational geographical zone relative to a sensor may include a step of simulating the position of said sensor; a step of determining a first zone of the region of interest; and a step of determining a second zone of the region of interest. The region of interest of the first zone may be constituted by points at each of which said object at that point traveling at a speed greater than or equal to said speed VT and in a given direction, would be seen by the sensor as having a radial speed greater than a threshold speed defined for that point. The operational geographical zone. may be defined by taking account of the intersection of the first zone and of a coverage zone of the sensor.

    Abstract: The invention relates to a double twisting twister machine with precision weave pickup, which is characterized in that the production modules are designed to work autonomously and independently and that it is especially designed with directly motorized spindles to work with threads having different diameters (titer) and both natural and synthetic materials wound in large size bobbins with precision weaving. The modules can work simultaneously at full capacity since all elements are independent.

  • Patent number: 6442922
    Abstract: Disclosed herein are a tire-reinforcing steel cord and a pneumatic radial tire using the same. The tire-reinforcing steel cord includes an inner layer consisting of 3 filaments and an outer layer consisting of 7 or 8 filaments and surrounding the inner layer. The inner layer and the outer layer are twisted in such a manner that they have the same twist direction and the same twist pitch length, whereby the number of the twisting steps in the manufacture of the steel cord is reduced, and also the penetration of rubber into the steel cord is improved such that the steel cord has an improved durability upon application to tires.

  • Patent number: 6378283
    Abstract: A process and apparatus for manufacturing multiple conductor cable having improved transmission parameters. The apparatus includes a rotatable alignment die having a plurality of apertures. At least one strand of the multiple conductor cable is caused to traverse an aperture of the rotatable alignment die. A rotation motor causes the strand to rotate about its elongate axis, and a translation motor causes the strand, or the cable, to traverse along its elongate axis. The multiple conductors are brought into a predetermined mutual mechanical alignment that is calculated to produce a cable having at least one improved transmission parameter. The cable can additionally include a support member adapted to maintain the conductors in the mutual mechanical alignment. A binder is applied to the cable to maintain the conductors in the predetermined mutual alignment.

  • Patent number: 6363705
    Abstract: A method for spinning fibers onto the free ends of the two threads of a yarn that is produced during an integrated spinning and twisting process and a two-for-one spinning and twisting apparatus for performing the method are provided. The method includes gripping a twisted yarn, separating two threads of the twisted yarn in a manner such that the twist which was originally present in each individual thread prior to the doubling of the thread with the other thread returns to the now separated thread portion, and forming a thread loop of each separated thread portion. Each thread loop is clamped and respective portions of the two branches of the thread loop extend to a spinning rotor and the spindle hollow axle. Spinning is commenced in coordination with winding and the thread loop is dissolved as the now joined thread is drawn into the spindle hollow axle.

  • Patent number: 6327843
    Abstract: A cord comprising at least a first pair and a second pair of wires (2a, 2b) of different diameter randomly disposed in transverse cross section thereof, is obtained by arranging in a nacelle (7) of a double-twisting laying machine, a twister (16) operating upstream of a preformer (15). The twister (16), rotating in a direction opposite to that of the impeller (5) and at a speed which is twice that of the impeller, neutralizes the internal torsional stresses induced in the wires (2a, 2b) by effect of the double twisting carried out upon the action of the impeller itself. Thus, a better control of the preforming operation executed on the wires (2a, 2b) disposed parallel in respectively coplanar axes is enabled.

  • Patent number: 6318062
    Abstract: A wire twisting machine and method provide a randomly varying lay to pairs of twisted wires forming a cable. A pair of wires are fed into a motor driven bow mechanism which twists the wires at a given rate of speed. The bow winding speed is sensed to provide a signal to a control system employing a computer which generates a randomly varying signal between a selected minimum and maximum range. The random signal is applied to an oscillator which provides a varying frequency signal to a power supply unit. A pulsed direct voltage signal then controls a stepping motor which applies the randomly varying lay signal to vary the speed of the capstan winding the wires with respect to the independent bow speed. This varies the length of lay of the twisted wires within controlled limits.
