Abstract: A temperature sensor for a radiant heater has a first tubular expansion element which is connected to its housing and contains a second rod-like expansion element, the two expansion elements having different coefficients of thermal expansion. The temperature sensor has two switching springs for different switching points. In order to adjust a second switching spring, which is fastened to a second switching spring base, the second switching spring base can be moved in the longitudinal direction of the rod and is then permanently fixed by bending or welding.

Abstract: The invention relates to a hydroxide aqueous suspension of at least one selected transition element of which the potential oxidation reduction is less than that of the pair CrO72?/CrO42? (?0.12 V) having a pH between 2 and 11, limits excluded, for reducing the content of chrome VI of cement to a value no greater than 2 ppm. The suspension is characterized in that it contains 0.5 to 80% by wt. of dry material of hydroxide of at least one transition element with regard to the quantity of water and in that it is stabilized by a hydrosoluble stabilizer. This suspension makes it possible to reduce the content of chrome VI of cements to a value no greater than 2 ppm.

Abstract: An electrical connecting device connects a conductor to a conductive strip carried by an insulating panel. The connecting device includes a base member having a mechanical attachment to a support, and a connector for electrically connecting the conductor to the base member. A conductive member is carried by the panel and is connected to the conductive strip. The conductive member projects along a rear face of the panel and has a surface for coupling to the base member. A mechanism mechanically attaches the conductive member in contact with the base member. The mechanism passes through the conductive member and includes a control region which is accessible from the front face of the plate.

Abstract: The electrical connecting device (16) is intended for connecting a conductor (18) to a conductive strip (12) carried by an insulating panel (10).

Abstract: The power distribution device comprises an insulating plate (12) and power conducting bars (14) carried by said plate (12). The device further comprises means for fixing the conducting bars (14) to a surface (18) of the plate (12). For at least some of the bars, the fixing means comprise a film of adhesive (20) interposed between the surface of the plate (12) and at least chosen zones on the surface of the bars (14) applied to the surface (18) of the plate (12).
