  • Electric relay having multiple operational thresholds
    Patent number: 4224588
    Abstract: Electric relay comprising flexible-blade switches having multiple operational thresholds. In this relay, the most sensitive switches are within the coil whereas the least sensitive switches are located outside the coil, the magnetic circuit being directed toward the outside switches by the use of magnetic flux detectors. Moreover, the operational thresholds of the switches are adjustable by the use of magnetic shunts disposed in the coil and in the flux detectors, one of the shunts being constituted by a material chosen for its Curie point.
    Type: Grant

    Inventors: Gerard Holvoet, Michel Nicolas
  • Control circuit for pneumatic phase
    Patent number: 4205700
    Abstract: The invention provides the functional reliability of an automatic device, constituted by the association of phase cells comprising, for each phase, a pneumatic AND gate and bistable memory, which is ensured by the interposition of a threshold relay between the feedback interrupter associated with a phase all and the control input of the memory.

  • Radar for short range measurements
    Patent number: 4014021
    Abstract: In a radar installation for measuring distances by transmitting and receig signal modulated by sequences of pseudo-random bits, generation both of the sequence of pseudo-random bits and of corresponding sequences with which the received radar signal is correlated, is controlled by a variable frequency clock. The frequency of the clock is varied to maximize the peak of the correlation function and the resulting frequency used to indicate the radar-target distance.

  • Swivelling coupling for fluid
    Patent number: 3980324
    Abstract: This coupling comprises a rotary cylindrical portion which is recessed and an outlet opening whose lower edge is placed level with the lowest point of a surface which is inclined relative to the rotation axis, whereby the said surface is placed adjacent to the axis and the side opposite to the said opening.This coupling is more particularly intended to be used on the inlets and outlets of pneumatic automatic control modules.
