Abstract: A device for manually opening a flexible package, in the form of a bag (1) made from plastics film which is closed by a weld line of closure (4) which is arranged at a filling mouth (2) in such a way as to leave a free skirt. The bag (1) has, at one side end of the filling mouth (2), a weakening line (3) of defined length which is located between the weld line of closure (4) of the filling mouth (2) and a free edge (5) of the filling mouth (2), with the weakening line (3) being directed in such a way as to be located in a contemplated trajectory of manual tearing of the bag (1). The trajectory intersects the weld line of closure (4) and extends across a corner (6) of the bag (1) immediately adjacent the weakening line (3), defining a delivery orifice (10). It is applied preferably to bags of the type for containing a plurality of articles which have to be maintained in a controlled environment and/or must be removed one by one through a small sized delivery orifice (10).

Abstract: A retainer device for conductors in an electrical raceway, which is applicable to raceways formed by the association of a U-shaped base section with a cover section. The base section is provided in the walls thereof with equidistant narrow transverse slots which define therebetween outstanding transverse tabs or strips which form a comb-like arrangement. The device is formed by an open narrow annular member of a right prismatic profile, the bottom portion thereof corresponds to the right internal cross section of the base section, of the raceway to which it is directed. The member has a bottom portion, two wall portions and two free end portions. The two free end portions are located at the level of the open side of the base section and face each other in an overhanging fashion and are partially overlapping. The two wall portions are provided with projections to interact with the walls and/or with the wall portion of an adjacent member.

Abstract: A box for installation of an electrical apparatus in a raceway for electrical cables. The box is fixed in the raceway which is formed by association of a base section and a cover section. The base section and the cover section are formed by the extrusion of a thermoplastic insulating material, wherein the base section is provided longitudinally on the inside of the edges of the walls thereof with shaped tubular beads, longitudinally forming an upper groove for the coupling of ribs of the cover section and a lower inverted spine opposite said groove. The box is formed by an upper portion and a lower portion, wherein the upper portion is attachable to the electrical apparatus and engageable in the groove of the shaped tubular beads. The lower portion is located with a slight clearance below the upper portion, and provided with a seating for the inverted spines of the shaped tubular beads.

Abstract: The device comprises: [a] a base member having a lower plate; an upper plate; a transverse wall extending between both plates; two first side walls, with a front portion attached to the lower plate and a rear portion associated with the upper plate and capable of being separated therefrom; and windows located in the upper plate and removable therefrom; and [b] a cover member having a front embouchure portion; a rear covering portion; second side walls and a rear wall. The cover member and the base member may be coupled together, defining an embouchure for communicating with an opening of an electrical apparatus; the removal of the rear portions of the first side walls opens a space in which a portion of a base section of a raceway containing electrical conductors may be housed.

Abstract: Each raceway stretch includes a base section, external walls; one or more compartment walls providing for the existence of sub-raceways, folds capping the walls and forming longitudinal slots and a cover section for each sub-raceway. The internal bottom surfaces of each base section are coplanar and have juxtaposable end cuts over the whole extension thereof. The elbow includes for each sub-raceway, an angled closing member having skirts engageable simultaneously in longitudinal slots of both raceway stretches, closing portions of a sub-raceway of each stretch; and a covering member which, in said active position, covers said angled closing members from above and is provided with means for engagement with said base sections.

Abstract: The device, in the active position thereof, provides for a connection between stretches of raceway, each of which includes: a base section with external walls and internal walls, providing for the existence of at least two sub-raceways, and a cover section. The internal surfaces of the bottom walls form between them a dihedral. For each sub-raceway, the device also includes a dihedral closing member, each provided with two end portions which, in the active position of the device, are respectively parallel to the internal surfaces of the bottom walls. Fixedly attached channel-like members project longitudinally from said end portions for connection to the walls of the base sections; and a covering member adapted to cover the closing members at least in part.

Abstract: The box is generally parallelepipedic and is provided with a bottom from which there extend major walls and minor walls. The major walls have first tabs of the same height, which are terminated by a suspension lip extending outwardly from the box. The minor walls are provided with two second tabs, between which there is a third tab having a reinforced lower region and a retaining tooth for engagement with an internal support frame of a raceway.

Abstract: A junction box for raceways applicable to a surface, formed by: an integral support base member including (i) a plate member, applicable to the surface and having an edge for fitting to a raceway; (ii) two tubular body members perpendicular to the plate member adjacent apexes having upper ends; (iii) adjustable members adapted to engage another raceway; and (iv) a first member for attachment to a lid member; a cable transfer member including: a structure holding removable sheet members and having a rear wall and a front wall; and being superimposable over the length of a raceway; and a lid member which is a hollow body having side walls and an upper cover and adjacent to house the base member and the cable transfer member.

Abstract: The device includes a support member; a casing; and a closing and covering member. The support member may be attached to an external member and may receive an electrical mechanism. The support member is provided with a coupling mechanism to the casing and this coupling allows access of conductors from a raceway device. The casing is prismatic in shape and is adapted to surround the support member and the electrical mechanism. The casing is provided with a bight in one side wall thereof. The closing and covering member has a wall portion and a hood portion. The wall portion may be attached to the edges of the bight to close it. The hood portion covers a portion of the raceway device. Where necessary, a guide member is attached to a portion of the raceway device and is covered by the hood portion.

Abstract: The device includes an inner frame to be situated on a base section of a tray, being attachable to grooves of the base section. The device also includes an electrical mechanism mounting plate being attachable to the inner frame, as well as being attachable to boxes containing the electrical mechanisms or to the electrical mechanisms themselves and with a retaining device to an outer frame. The latter is attachable to the inner frame which it completely covers and also is attachable to the grooves of the base section.

Abstract: The member or box includes: a slot under which ribs of the tray may be received and which has passages on one side and an aperture on the other side; a retaining member attached to the slot and which is provided with a fold-down tab and a tooth; fingers resiliently attached to the base portion and provided with teeth inserted through the passages and which may retain a rib; and resilient bridges extending on a higher plane above the base portion and facing the tab. The retaining member is movable between a normal inactive position and an active position in which the tooth is inserted through the aperture, retaining one of the free ends of the rib and the bridges retain the fold-down tab.

Abstract: A device for joining trays includes a transverse portion and a sheetlike buttstrap.
