Abstract: A rope arresting apparatus for use with a rope having a first end and a weighted second end is disclosed. The rope arresting apparatus includes a cam portion for exerting frictional force on the rope and a pinching portion. The cam portion has a resting position and a pinching position. At the resting position, the cam portion is in frictional contact with the rope when the tension on the weighted second end of the rope is less than or equal to tension on the first end of the rope. A pinching point is formed when the cam portion at the pinching position engages the rope against the pinching portion.

Abstract: An embeddable breakaway utility pole comprises separate upper and lower aluminum pole pieces, wherein the lower pole piece is to be embedded below ground surface. The upper and lower pole pieces are interconnected by a weld which defines a breakaway zone enabling the upper pole piece to break off the lower pole piece in response to vehicular impact. The weld can be connected to a backer ring which provides a guide surface that axially aligns the pole pieces. Alternatively, the pole can be formed of a single pole piece which is welded between its ends to form a weakened region that defines the breakaway zone.

Abstract: A breakaway pole installation includes a vertical pole having an anchored lower section anchored to a foundation and including a breakaway device for fracturing upon an impact of predetermined force. A decorative cover extends around the pole's lower section. The cover includes a lower foot and an upper lip. The pole includes an outward bump-out situated within the cover. The bump-out includes an energy transfer portion spaced below the cover's lip and above the cover's foot for transferring impact energy from the cover to the pole. The energy transfer portion has a height extending at least 60 mm above and 60 mm below a point of impact disposed about 450 mm above the foundation. The energy transfer portion has a maximum horizontal spacing from the cover of up to about 6 mm.

Abstract: A highway lighting apparatus includes a lighting fixture, and a vibration damper. The vibration damper includes a housing having a ball chamber, the chamber being of square shape. One or two vibration damping balls are mounted in the chamber for independent free rolling movement therein. If two balls are used, the ball diameter is shorter than one-half of each of the four chamber sides. If the damper is used on a pole having a side-mounted light fixture, the housing would include a downwardly open socket receiving the top end of the pole, with a center axis of the pole coinciding with respective center axes of the chamber and the socket. In the case where the damper is used on a pole having a top-mounted light fixture, the damper would be mounted below the light fixture on a side of the pole.

Abstract: A breakaway transformer base for a lighting pole includes four upstanding corner members (preferably formed of aluminum castings), and four side sheets. Each side sheet is attached to two of the corner members, e.g., by welds or fasteners, thereby interconnecting the corner members. Each corner member forms bolt holes for enabling the base to be bolted to a lighting standard and to an anchored foundation.

Abstract: A pole vibration damping means includes an annular housing with internal radial pole encircling chambers in which lead spheres are provided for effecting damping of first mode harmonic vibrations with the assembly being attached to the upper end portion of the pole and operating in conjunction with a pole vibration damping device mounted medially for damping second harmonic mode vibrations.

Abstract: A hollow aluminum pole has access to its interior through a hand hole frame having an access aperture which can be blocked by a cover having a lower end pivotally attached to the hand hole frame by a pivot pin. The pivot pin is biased inwardly by a coil spring which permits outward movement of the cover to a position in which it can be rotated downwardly out of alignment with the access opening.

Abstract: The electromechanical device of the present invention is a low profile reed switch package for surface mounting on a printed circuit board. The reed device package includes a reed switch with two signal terminals emanating from opposing sides thereof. A leadframe is employed with signal conductors and ground conductors. The signal conductors are respectively attached to each of the signal terminals. A ground shield surrounds the body of the reed switch. The ground conductors are connected to the ground shield on a first side of the reed switch with the signal conductor on one side of the reed switch being positioned between the two ground conductors. Another pair of ground conductors are connected to the ground shield on the other side of the switch and are similarly positioned with the other signal conductor positioned therebetween.

Abstract: A magnetic rotational position sensor comprises a loop pole piece, at least one magnet, and at least one magnetic flux sensitive transducer. The magnet is disposed within an air gap of the loop pole piece to establish a magnetic field through the air gap and to enclose magnetic flux within the loop pole piece. A control shaft is rotatable about a first axis and the loop pole piece and the magnet are adjoined to the control shaft to synchronously rotate the magnetic field about a second axis. A working air gap area is defined within the air gap area of the loop pole piece between a pole surface of the magnet and an inner surface of the loop pole piece. A magnetic flux sensitive transducer is disposed within the air gap to sense a magnitude of magnetic flux density.

Abstract: A new board mounted electromechanical device is provided that mounts to a relay substrate to form a low profile reed relay. The reed relay is electrically connected to the electrical contacts via a signal traces and additional electrical traces located on the same side of the relay substrate which connect to the relay's signal and shielding. Additional traces on both sides of the signal traces of the reed relay provide a co-planar wave guide to maintain the desired impedance of the signal path. The reed relay is mounted in an inverted manner into a cut-out in the main circuit board so that the other portion of the reed relay itself is sits within the cut-out in the main circuit board. As a result, the reed relay component is recessed below the surface of the main circuit board resulting in an overall low profile circuit board.

Ground vias extend through the main body and respectively connect to the ground terminals. The grounds vias are on opposing sides of the signal via and lie in the same plane as the signal via. The signal and ground via exit at the bottom of the main body and are connected to a circuit via solder balls to provide a compact surface mount package with a controlled impedance environment.
