Abstract: A molded concrete member has two facings, respectively active and passive, spaced from one another by a preselected distance, and between which is embedded a reinforcing cage. The cage has, on either side of a neutral axis, two layers, respectively active and passive, which are separated by a spacing. Each layer has at least one longitudinal solid bar of preselected cross-section, the spacing and the cross-section of the bars being determined in relation to loads to be applied, the two layers are respectively parallel to both facings of the molded element and are connected by transverse linking armoring.

Abstract: An apparatus for limiting ice build-up in a gutter, the apparatus deployable in a gutter which has a bottom, the apparatus comprising a housing comprising sidewalls and a base comprising a top side, the sidewalls joined to the top side of the base with the side walls defining a salt block opening through which the salt block is loadable into the housing, with one of the side walls defining a flow opening for allowing frozen precipitation to pass therethrough and contact the salt block and melt.

Abstract: The present invention relates to a fastening technique for installing grille panels in frame sections that is faster and more secure and does not require tools. The grille is effectively secured against detachment from the frame, as the grille connectors are positively prevented from being pulled out of the grooves. Consequently, large pushing, pulling and detachment forces can be exerted on the grille without damaging the grille connectors.
