A device for guiding a flexible elongated element such as a cable or the like, designed to guide the element during a drawing process, and comprising several rollers mounted pivoting about an axis and arranged such that they define a space for receiving the element and whereof the contour is substantially closed, the shafts of the rollers being borne by a support capable of opening into two parts whereof one is mounted articulated relative to the other; a first part is a bent flat iron such that it is formed by three abutted U-shaped brackets, two brackets being arranged facing each other and coupled each with the end of the wing of the other bracket whereof the web extends perpendicular to the parallel webs of the two brackets and the second part is a flat iron bent so as to form a bracket similar to the brackets of the first part but whereof the ends of the wings, not coupled to the web of the U-shaped bracket, are prolonged along two lugs extending outwards of the U parallel to the U web.

A bracket for cable tray type conduit carriers constituted by three principal perpendicular walls forming a trihedron, a dorsal wall, a fixing wall for fixing conduit carriers and a lateral wall. The bracket is mounted to a U-shaped rail via a rod passing through a perforation in one side member of the rail, a hole in the lateral wall, bearing on a projection in the dorsal wall and finally passing through a facing perforation of a second side member of the rail. The fixing wall is provided with a system of notches out across the edge between the fixing wall and the lateral wall, the notches dividing the fixing wall into separate islets and being surmounted by tongues provided in the fixing wall over a fraction of the length of the notches. Notches constitute housings for longitudinal wires of wire mesh cable trays, the tongues being able to be bent down onto the wires.

A suspension bracket can be mounted on a rod, such as a screwthreaded rod, and has a metal body including a hook-shaped support part and, opposite the support part, a substantially plane fixing part including a notch. At the entry of the notch, a retaining lug upstanding from one of its edges extends obliquely to the plane of the notch at a distance from the opposite edge of the notch, enabling the rod to pass between them.

The invention is a coupling assembling first and second wire cable tray unit sections. The coupling is an elongate rigid strip divided into two arms with each arm provided with mounting means. The mounting means on the first arm alone rendering the coupling solid with the first tray unit section without permanent deformation of the mounting means. The mounting means on the second arm resiliently latching the second arm to the coupling without permanent deformation of the mounting means on the second arm.

A supporting element for lattice structures comprises at least one channel shaped structural section including an endwall flanked by obliquely oriented adjoining wings. Regularly longitudinally spaced securement notches are provided for securing lattice or wire cable trays the supporting element. The notches comprise longitudinally extending cutouts in each of the wings. The cutouts are defined by longitudinal and lateral edges in the wings. Regularly spaced lands extend between successive notches. Tongues longitudinally extend from the lands and partly overlying the notches. Gaps are defined between free edges of the tongues and adjacent lands. The tongues are bendable from a position generally in alignment with associated lands to a deformed position extending into the notches for restraining a section of the components between an underface of the tongues and the edges in the wings. According to a preferred embodiment two such channels shaped structural sections are joined by a common basewall to define a one-piece omega-shaped section. An X-shaped beam is also provided comprising omega-shaped sections fixed together at their basewalls.

The present invention relates to installations for supplying the burners of boilers with an emulsion of fuel, water and if desired soluble oil, intended to ensure the elimination of 95% of the solid unburnt material in the combustion gases of boilers and hot air generators and to eliminate the liquid residues by incineration. The installation includes a reserve tank fed by an electrovalve controlled by a level-electrode provided in the tank so as to maintain a constant level of liquid, a pump, an emulsifying device and at least one burner, together with a regulating valve acting on the flow of liquid to be treated in dependence on the temperature of the mixture after its passage through the emulsifier, this valve being mounted between the pump and the emulsifier.

A workpiece-supporting table of an electro erosion machining equipment is provided with a mechanism for subjecting the workpiece to a circling motion of continuously variable radius during operation from zero to a maximum value. The same tool electrode can be used, without withdrawal from the work, for coarse machining at first and fine machining under circling movement immediately thereafter.
摘要:
The invention concerns a wire cable rack (10) for supporting and fixing electric cables (16), locally equipped with at least a fixing accessory (18), including fastening means (20, 21) through which it is made integral with the wire cable rack (10) panel which is equipped therewith, and with at least a hole (22, 23) which runs right through it, and by which it can receive any fixing element, such as a clamp fitting (17), bolt or the like.

The invention concerns a coupling for assembling wire cable tray unit sections. It comprises two arms (55, 56). Means (57, 58) for mounting the first arm (55) can independently catch the coupling on the first unit section (51, 52). Means for mounting the second arm (56) on a second unit section (53, 54) comprise at least one resilient catch means (60) which can co-operate with a transverse wire of the second unit section (54) during assembly of the two unit sections. The invention also concerns a cable tray unit section comprising pre-mounted couplings.
