  • Patent number: 5594211
    Abstract: A split solder sleeve is provided with a conductor channel extending between open opposite ends of the sleeve and a longitudinal slot extending through the side wall of the sleeve into the channel and between the ends of the sleeve. The improvement includes a hole extending through the side wall of the sleeve into the conductor channel. The hole allows solder to be poured into the sleeve and around the conductors directly on the ends of the conductors. The hole allows greater visual inspection of the spliced solder joint both during and after pouring of the solder.

  • Patent number: 5583317
    Abstract: A controlled oxygen content copper clad laminate product. In accordance with one aspect of the present invention, there is provided a laminate having a first layer of oxygen-free copper joined to a second layer of oxygen-rich copper by the steps of (i) cladding the first layer to the second layer at a relatively low speed to minimize rolling friction, (ii) finish rolling the laminate to substantially increase its thickness tolerance, (iii) slitting the laminate to increase its width tolerance, (iv) profiling a groove at a selected location in the laminate, (v) finish slitting a plurality of ribbons from the laminate, (vi) tension leveling the laminate to straighten and flatten its shape, (vii) stamping the laminate into sections each of a selected configuration, (viii) cleaning laminate surfaces, and (ix) direct bonding the laminate to a substrate material such that the first layer is annealed to the second.

  • Patent number: 5583316
    Abstract: A cooling device mounting a fan unit (3) above a heat sink (2) mounted on a heat-generating element (1) or buried therein, which produces an effective air flow and achieves a uniform cooling action by having the heat sink (2) comprised in various shapes. Further, a cooling fan disposed away from the heat sink (2) or to the side of the same is used for effective cooling through an air conduit passage formed by pipes or a cover.

  • Patent number: 5576514
    Abstract: In order to provide a coil type high-voltage resistive wire having a lower resistance than and a noise preventing performance similar to a prior art resistive wire while maintaining an inductance level without increasing a diameter and a winding pitch of a resistance wire, a core (3) consists essentially of a center reinforcing core (1) which is obtained by twisting three aramid fibers of 1000 denier and a ferrite core (2) having an outer diameter of 1.3 mm or smaller which is obtained by extruding a mixture of resin or rubber base and ferrite powder around the center reinforcing core (1). A resistance wire 5 made of a copper-nickel alloy wire having a diameter of 35 to 55 .mu.m and an electrical resistivity of 5 to 35 .mu..OMEGA..cm is wound around the core 3 at a pitch of 10000 winds/m or larger in a direction normal to the longitudinal axis of the core (3), so that the resistance value of the resistance wire (5) as a conductor can be set at 4 to 7 k.OMEGA./m.

  • Patent number: 5567914
    Abstract: An article such as a conduit or cable, or a splice closure for a cable, is provided with improved resistance to animal damage by applying a layer of abrasive material to the article. The abrasive material is not only sufficiently hard and thick to act as a physical barrier, but its abrasive nature creates such a harsh, unpleasant grating effect that the animal tends to not attack it at all. The preferred embodiments of the article use either a plurality of granules to form the abrasive material, or a mesh substrate having an abrasive coating thereon. The material should have an effective grit value of no more than 325, and preferably no more than 100. The abrasive material may be applied using an adhesive or, where the conduit/closure is a thermoplastic polymer, various methods are provided for embedding the abrasive material in the polymeric wall.

  • Patent number: 5561269
    Abstract: A cable splice enclosure (10) including a pair of cover members (12,14 ) joined along a flexible hinge (62,64) and rotatable together about the hinge to enclose a cable splice (150) and secure to each other with latches along both side edges (16,18;92,94 ). Sealant material (120) disposed within central regions (32,34) of both covers environmentally seals the surfaces of the splice connection (154,158,160) upon full closure. Embossments (44,46 ) on both sides of the cable-receiving channels (20,22) in associated pairs (40,42,48) proximate the cable exits include resilient flange portions (52,54) cooperate to press into the cable insulation upon full closure to define a strain relief. The enclosure (200) may be used to splice aerially suspended cable (202) by grooves (208) between the hinge (216) and the latches (218) proximate the hinge (216), receiving thereinto a length of suspension wire (206) spliced to suspension wire (204) thus securing enclosure (200) to cable (202).
