  • Patent number: 5157853
    Abstract: A C-shaped support for cable marking has a lengthwise straight or S-shaped slit and at least one of its ends has one or more oblique surfaces running counterclockwise or clockwise with respect to the longitudinal central axis and with respect to the position of the slit. Before its installation on the cable, the support is positioned so that the oblique surface can be rotated clockwise or counterclockwise to widen the slit which will then close again progressively.

  • Patent number: 5035048
    Abstract: A marking machine for marking cable markers has a frame bearing a plurality of strips of ring shaped marking elements, a tab mounted on a reciprocating carriage, and devices for positioning a ring-shaped marking element of each strip in the travel path of the tab. The tab automatically seizes the selected element and introduces it in a recess of a cable marrier.

  • Patent number: 4899474
    Abstract: This open sleeve support is consisting of a central flat or slightly curved part (1), preferably of constant thickness, provided with two lateral branches (2) growing more narrow downwards, the latter being connected through a small fillet, to the two flat and parallel flanges (4) bent inwards and almost reaching the center of the sleeve, so that the support can be easily fitted on cables of various size (7) by slipping the sleeve on laterally, without risk of failure, while remaining firmly in place.

  • Patent number: 4876810
    Abstract: This open support has the configuration of a "C" shaped sleeve (1) provided along the free ends of the "C" with two opposed lateral shapes (3) connected by weakened zones (2); each shape being provided with an inwards directed upper thin triangular projection (4) and a lower convex projection (5) so that during the assembly of the support (1) on the cable (6) the sleeve (1) is subjected to elastic strain and the shapes (3) begin to oscillate around the weakened zones (2) so that, due to an elastic thrust of the shapes (3) acting on the external lower semicircumference of the cable (6), the latter is pushed inwards and will snap into the sleeve (1) causing a further oscillation of the shapes (3) until they reach their end position while pushing the cable (6) inwards by boundary pressure.

  • Patent number: 4861280
    Abstract: This terminal is consisting of two elements, one of which is formed by a metal coupling mechanism (1) a first ring (2) connected to the coupling mechanism (1) and a second ring (6) connected to the first ring (2) by means of a narrow lower link (5), so that the second ring (6) is externally projecting beyond the first ring (2), whereas the other element is formed by a hollow, tubular insulating envelope or sleeve internally featuring various subsequent shapes, i.e. a flaring or bellmouth (8) forming an initial step (9), followed by an annular recess (10), a second step (11) almost centrically located with respect to a cylindrical end section (12), so that the terminal to be used by the operator is obtained by introducing the second ring (6) in the sleeve (7) until it is positioned in the annular recess (10) and resting against the first step (9). After connection to the lead by crimping the first ring (2), the sleeve is moved axially so as to uncover the coupling zone, i.e.

  • Patent number: 4603924
    Abstract: A support for multiple strips, comprising a casing having identical upper and lower faces with transverse grooves and an alignment hole therein, lugs are provided on at least one side of the casing, the lugs forming female hinge parts, and walls are provided for covering each face of the casing, the walls each having a plurality of transverse webs forming a plurality of slits therebetween, the webs having a T-section along part of their length and a square section along another part of their length, the webs extending into the grooves, the walls having a pin arranged to enter the alignment hole to obtain registry of the wall with its associated casing, the female hinge parts of one casing being operable to cooperate with the female hinge parts of another casing to hingedly connect one casing to another casing.

  • Patent number: 4586671
    Abstract: This invention relates to dispensers comprising one or various interconnected holders, the or each holder being formed by two box-shaped components with an outlet opening in which a rotary drum is housed. A flexible strip or elements of any suitable nature is wound around the drum, to be used together with elements of other strips for marking of wires, cables, electrical equipment and systems. These strips of elements protrude from the hole in each holder and can be cut to any length and removed progressively by turning the drum. A multiple holder dispenser provides for tidy and methodical arrangement of the marking elements and for easy and safe utilization.
