  • Patent number: 6255613
    Abstract: A revised structure of a distribution box of an on-line switch essentially comprised of a distribution box base, wherein four separated wire slots are formed and the left, right and base of the slot are in the shapes triangular of pyramid convexes, a box cover, wherein wire-pressing convexes which correspond to the convexes of the distribution box base are made, and a control element, which is inserted in the space created after the distribution box base and the box cover; after the electric wire being inserted in the wire slots and the distribution base and the box cover being assembled, the convexes can compress the electric wires in four directions and in turn grip the electric wires firmly, preventing the electric wires the risks form loosening, or even falling off, under improper pulling.

  • Patent number: 6133813
    Abstract: A relay has a leaf spring that is secured to a planar seating section of a yoke leg and/or to the planar seating section of the armature and has an unsecured spring section extending beyond the free end of the yoke leg or, respectively, the armature. In order to avoid a plastic deformation of the leaf spring given impacts, the planar seating section respectively merges into a convexly curved roll-off section of which the leaf spring rolls off given a blow without being bent permanently. The end of the roll-off motion is expediently limited by a detent and, in this way, it is assured that the relay does not suffer any permanent modifications of its characteristics, even given heavy blows.

    Abstract: An electromagnetic actuator includes an electromagnet having a yoke and an operating coil supported by the yoke and connectable to a controllable current supply for effecting a current flow through said operating coil. An armature is movable from a first position remote from the pole face of the electromagnet to a second, pole face-engaging position in response to a first electromagnetic force generated by a current flow through the operating coil. A resetting spring is coupled to the armature and opposes the first electromagnetic force. Further, a circuit is provided which is formed of a braking coil supported by the yoke and a switching element having open and closed states. The circuit is closed in the closed state of the switching element and is in the open state of the switching element.

  • Patent number: 5973280
    Abstract: A circuit breaker handle is provided with a curved bearing surface at its pivot point. The handle bearing surface has a substantially constant radius and is connected to the body of the handle with a necked down handle extension. The handle extension has a width that is less than the width of the curved bearing surface at the point of connection between the bearing surface and the necked down region. The handle pivot mates with a corresponding bearing surface on a notch in the side plate that it pivots within. The arc of the curved bearing surface in the side plate is greater than that of the corresponding bearing surface on the handle and captures the handle pivot within the notch in the sideplate, so the handle cannot lift off the bearing surface on the notch as it is moved.

  • Patent number: 5920248
    Abstract: A multipolar magnetic ring that generates a sinusoidal magnetic field has a cylindrical shape and two magnetic poles, north (N) and south (S), which are imbricated one in the other in such a manner that their widths (L.sub.p) are equal and constant. Two magnetic transitions between each of the two poles each follow a continuous curve that moves by one half pole width for each quarter of a turn of the magnetic ring, with the two curves being shifted by so that the magnetic field has a single period per turn of the magnetic ring. The magnetic field is implemented either along two spirals (s.sub.1 and s.sub.2) on one of the flat faces, or along two helixes (h.sub.1 and h.sub.2) on its cylindrical side. The magnetic ring may be used in absolute-position sensors, notably in bearings.

  • Patent number: 5804772
    Abstract: Apparatus and a method for aggregating a desired number of articles without individually counting out each article to achieve the desired number. A stream of the articles is discharged into a weigh hopper until substantially a predetermined weight of articles is in the hopper. The number of articles in the hopper is determined from the total weight of the hopper and the weight of a single article. Additional articles are caused to enter the hopper one-by-one until the desired total number of articles is contained in the hopper. The contents of the hopper are then packaged for distribution.
