  • Retaining clip for trunking, in particular trunking for electrical devices
    Patent number: 6513289
    Abstract: A retaining clip for trunking includes a fixing base attached locally to a longitudinal wall of a base section of the trunking, such as an internal partition thereof, and a retaining flap which is articulated to the fixing base and can move from a standby position, in which it allows unrestricted access to the underlying interior volume of the base section, to a service position, in which it closes that interior volume at least partly, extending substantially transversely relative to it. The retaining clip includes, independently of any member or component of the base section or of the trunking, a releasable locking system for locking the retaining flap in its service position.

  • Control device for an appliance adapted to assume a level selected from a range of levels, method of controlling a roller blind using the device, and user module for the device
    Patent number: 6512338
    Abstract: A control device for an appliance which can assume a level selected from a range of levels includes a keypad representative of the range of levels to enable a user to select a level, an “off” key for switching off the appliance, and a processor unit connected to the keypad and to the “off” key. If the appliance is off and the keypad is operated to select a target level, the processor unit causes the appliance to assume the selected target level. If the appliance is off and the “off” key is operated, the processor unit leaves the appliance off. If the appliance is on and the keypad is operated to select a target level, the processor unit causes the appliance to assume the selected target level if that level is different from its current level. If the appliance is on and the “off” key is operated, the processor unit switches off the appliance.
