  • Patent number: 5233294
    Abstract: A proximity sensor using the magnetic field of a single length of sensor wire. The sensor has a supply circuit for generating a magnetic field around the single sensor wire. The sensor also has a detection circuit for detecting when electrically conductive material intercepts the magnetic lines of flux of the magnetic field surrounding the single sensor wire. In a preferred embodiment the sensor wire is substantially straight and/or the detection circuit detects metal within a distance from the sensor wire approximately two or three times the main dimension of the cross section of the sensor wire. A plurality of sensor wires can be used and a passive actuator or scale can be used to intercept and alter the magnetic field surrounding the sensor wire. The scale can be formed of electrical short circuits aligned at constant steps. The sensor then detects the presence or absence or a short circuit in the magnetic field.

  • Patent number: 5224032
    Abstract: The present invention pertains to a process and a system for controlling the movements of an axis on program-controlled machines, especially industrial robots, comprising a position control unit and/or a velocity control unit and/or a power control unit. The loads acting on the axis from the outside during the operation are measured by one or several sensors. The load signal is fed back regeneratively in the sense of an increase in the position control variance and sent to the summation point of the position and/or velocity control unit. To increase or decrease the mechanical flexibility of the axis, a controllable amplifying or attenuating device is provided. The sensors may have different designs, corresponding to the loads to be measured. They are preferably directly associated with the axes.

  • Patent number: 5223069
    Abstract: With the splicing get started, braking becomes strong and the old core decelerates, when the capstan roll comes to be free run. The speed reference to the second motor is a summed-up speed of "line speed minus capstan speed" and compensated portion of the tension. At once when the old core starts deceleration, the accumulation roll unit starts moving. The capstan roll is accelerated at a certain rate, when the new core is drawn out, up until the speed reaches "line speed plus overrun speed". When the accumulation roll unit reaches the synchronous position, the overrun becomes "0" and the capstan roll synchronizes with the line speed.
