Abstract: The iron-based piping element (1), in particular made from cast iron, for a buried pipeline, includes an outer coating (9) including: a first layer (11) having at least one porous layer of zinc/aluminum alloy containing 5 to 60 wt % of aluminum; a second layer (13) of adhesive situated on the first layer (11); and a third layer (15) situated on the second layer (13) and including a synthetic organic material. The method for manufacturing such a piping element is also described.

Abstract: A feeding and aligning device for a folder-gluer of blanks of folded and pasted cardboard boxes has at least one thrust to stop the blanks in order to crosswise align the angles between the various fold-pasted parts thereof before introducing them into a delivery area where these blanks are pressed. A mechanism introduces the blanks into the delivery area. The thrust has a driving mechanism that defines a moving trajectory for the thrust above the blanks, forming an acute angle with the conveying direction of these blanks which are moved by a conveyor that moves it along the conveying direction.

Abstract: An electric switch assembly including a multipolar quick-assembly appliance and a quick-connect appliance, wherein the body of an appliance, or its power terminal strip, is directly fixed and interlocked with to the body of an adjacent appliance. The interconnection between the various appliances is rapidly performed by multipolar blocks capable of being pressed on the front surfaces of appliances and being elastically plugged into their terminals.

Abstract: The invention relates to an electromechanical contactor, comprising a mobile push-piece which is connected to the contact support and can be accessed via a front face. A cover in the form of a plate is removably mounted on the front part (10a) of the housing (10), on fastening elements (17,19) provided for mounting an additional bloc. Said cover provides a means of masking the mobile push-piece (16) and has a transparent section (21) in front of the push-piece which prevents it from being activated manually without altering the ability of the device to display the state of the contactor.
