  • Patent number: 6194659
    Abstract: A cable insertion device comprising a seat having an opening, and an engagement portion extending peripherally around the opening axis, the engagement portion having an outer surface and, recessed relative thereto, an inner surface. The engagement portion is circularly segmented into grip jaws capable of elastic deformation by slots extending right up to the seat. At their connection with the seat, the grip jaws are each fixed therein along a fixing zone tangent to a circumference centered on the seat opening axis, and, with the engagement portion, which is made of relatively rigid material, is associated a sealing member, extending globally transverse relative to the seat opening axis, concealing at least partially the opening, and the sealing member is made of a relatively flexible material. The invention is useful, in particular, for equipping any chamber, such as a cabinet or the like.

  • Patent number: 6060793
    Abstract: An electronic switch has an input terminal, an output terminal and an electronic switch unit between the input terminal and the output terminal controlled by a control circuit which extends from its anode to its trigger and is under the control of an actuator which the user can operate directly or indirectly. There is a current limiter resistor in series with said control circuit. The value of the current limiter resistor is less than the value of the voltage on triggering of the electronic switch unit divided by the minimal trigger current needed by the electronic switch unit for such triggering. It is in the order of 40 ohms at most, for example. Applications include controlling a load without generating spurious harmonics which are a problem on the mains supply.

  • Patent number: 6057654
    Abstract: In a method of automatically controlling a lighting load to which are delivered alternately forced turning on instructions and forced turning off instructions, according to the result of comparing the brightness measured in a given area and particular brightness thresholds, the brightness threshold used to deliver a forced turning on instruction, hereinafter called the comfort threshold, is left for the user to determine. In a normal operation phase, i.e. after an initiation phase, the brightness threshold used for delivering a forced turning off instruction is the sum of this comfort threshold and the brightness difference between the brightness measured before the previous forced turning off instruction and the brightness measured immediately after that forced turning off instruction. Applications include automatic control of fluorescent tubes with a non-electronic ballast.
