Abstract: The present invention relates to aerial power transmission lines, and more particularly to devices for suppressing the galloping of aerial conductors, specifically to an aerodynamic aerial conductor vibration damper.The essence of the invention resides in that an aerodynamic aerial conductor vibration damper comprising an elongated plastic plate and a member clamping said plate to the conductor is such that said clamping member is also made of plastic and forms an integral part of said elongated plastic plate. Said member clamping the elongated plastic plate to the conductor is made in the form of a split sleeve the internal diameter whereof is less than the external diameter of the conductor so as to be interference-fitted thereon covering more than 180.degree. of its circumference, and said clamping member is so disposed with respect to said elongated plastic plate that its generatrix is directed along the latter.

Abstract: In an elevator including weight-compensating ropes having their respective one end connected to the lower end of a car and the other end thereof connected to the lower end of a counterweight, an oscillation-absorbing device is provided closely adjacent to at least one of a first connecting portion of the main ropes to a car or the counterweight and a second connecting portion of the weight-compensating ropes to the car or counterweight, thereby absorbing oscillation energy from ropes.

Abstract: A spacer-damper for overhead transmission lines of at least three subconductors comprising arms, one for each subconductor, mounted by resilient damping means to a rigid frame. Each arm has a cable clamp at one end and at least two of the arms extend from the frame so that a line between the clamp and the other end of the arm is in a direction generally perpendicular to a plane including the axis of the bundle and the center line of the subconductor engaged by the clamp.

Abstract: There is disclosed a spacer-damper for electrical transmission cables or the like. A rigid spacer composed of mating half-sections has defined at its extremities hollow spherical sockets for receiving the spherical end portions of individual cable connector structures. The opposite ends of the connectors are fashioned for effecting a gripping connection with a cable. A resilient damping material is interposed between the spherical connector end portions and their associated receiving sockets and the damping material is secured to both the ball and the socket so that on pivoting of the connector arm attendant cable vibration or oscillation the damping material is placed in shear to effect a damping action.

Abstract: A seismic damper device is provided between the supporting plate adjacent the bottom of an upstanding piece of electrical apparatus and the lower main frame support members, supporting said upstanding electrical equipment, so that any relative motion between the upstanding column structure and the main lower-disposed frame support structure is restricted. Preferably, a liquid-filled dash-pot assembly, or energy-absorbing device, is utilized at one or more locations extending between the lower supporting plate member of each upstanding column structure and the lower-disposed main supporting framework.In one form of the invention there are provided three equally-spaced radially-extending support arms extending outwardly from the main supporting plate disposed adjacent and fixed to the lower end of each upstanding column structure.

Abstract: An ultra light weight, frameless damping spacer for spacing three parallel, overhead conductors, the damping spacer comprising three rigid spacer arms and conductor clamping members, with the clamping members being respectively located at one end of the spacer arms, and integral housings respectively located at the other ends of the arms. Each housing is provided with an opening and a damping spring wholly contained within the opening and housing. The spacer arms are disposed together to form an internal triangle (the spacer arms) and an exterior triangle (the conductor clamps). A rigid pin connects together a pair of the arms adjacent the corners of the structure.

Abstract: A spacer-damper for a sub-conductor bundle of two or more sub-conductors of an overhead power transmission line comprising an arm for each sub-conductor, each arm having provided at one end a clamp for attachment to a sub-conductor and at the other end a resilient connection connecting said other end of the arm to a lever means extending between one arm end and another arm end wherein the lever means comprises at least two levers interconnected by resilient means to act in series between the connected arm ends whereby sub-conductor movement causes displacement of the resilient connections and of the resilient means.

Abstract: A spacer-damper for overhead power transmission lines wherein a rigid arm is provided for each sub-conductor mounted on a rigid frame by a damped resilient connection member which provides damped resilient movement in all directions of arm movement.

Abstract: A damper for an overhead transmission line comprising a torsional bar disposed in a spaced and parallel arrangement with conductor means of an overhead transmission line; a fixture spacer to fix one of the ends of said torsional bar to said conductor means of the overhead transmission line; at least one bearing spacer to bear the other end of said torsional bar on said conductor means of said overhead transmission line so that said torsional bar is allowed to be twisted; and a pair of weights having an equal inertia moment and secured to said torsional bar adjacent to the torsional end and on either side thereof.

Abstract: This invention carries a power cable from a floating power plant to a fixed connection from which the power cable can transmit to a distributing system on shore. The cable support distributes the bending of the cable over a length of cable so that no deterioration of the cable occurs as the result of successive bending and unbending with the tidal motion of the floating power plant. A jointed cover protects the cable support from exposure to the weather and from icing.

Abstract: A device for spacing overhead, parallel subconductors of a conductor bundle and for damping vibrations of the subconductors. The device comprises rigid, elongated arms pivotally connected together at one end of each arm and having a clamp at the other end of each arm for attaching the arms to respective subconductors. A resilient, viscoelastic pad or disc is disposed between the arms in opposed recesses provided in the arms at the location at which the arms are pivotally connected together, the pad or disc providing the primary damping mechanism for the device.

Abstract: A device for spacing overhead, parallel subconductors of a conductor bundle and for damping vibrations of the subconductors. The device comprises rigid, elongated arms pivotally connected to each other by a rigid means at one end of each arm, with the other end of each arm being radially spaced from the rigid means and provided with a clamp for attaching the arm to a subconductor. Resilient damping devices, such as close coil springs, are secured in the arms at a location adjacent the rigid means pivotally connecting the arms to each other.
