A street lighting assembly includes an LED lighting device and a printed circuit board disposed within the LED lighting device. The printed circuit board includes an LED light module and an LED driver, the LED driver being electrically coupled to the LED light module. An optical cover is disposed over the LED light module.

A joint exhibits high tensile strength. The joint includes a solid rod having a slit or opening into which a wedge is inserted. The rod and wedge are inserted into a fitting. The internal surface of the fitting has a contour which continuously and nonlinearly varies with distance along the fitting. The wedge has a dimension having a similar contour. The shape of the contour can be described by a polynomial of order two or higher. The joint can be used to construct a sucker rod for an oil well, or it can be used in other applications. The joint can support high tensile loads, over long distances, while occupying a very narrow tubing bore.

A connector (13) for coupling a first hollow elongate member to a second hollow elongate member, the connector comprising a linkage (15) having a first end region (17) and a second end region (19); a first expandable retainer (21) coupled to the first end region (17) of the linkage (15), and a second expandable retainer (23) coupled to the second end region (19) of the linkage (15).

A method of manufacturing a hydraulic plug. A shell with a circumferential wall, a sealed end, an open end and an axially extending cavity within is provided in which the cavity is defined by an internal surface with an inner diameter which narrows towards the open end. A head of an expander is inserted into the cavity, the expander further comprising a stem extending from the cavity for applying a tensile force (T) to the head. A sleeve is provided on a stem side of the head extending into the cavity, an end of the sleeve adjacent the head having an inner diameter which is less than a maximum outer diameter of the head. The sleeve is formed by expanding the sleeve by forcing the head into the end of the sleeve through urging the sleeve and/or expander towards the other in an axial direction.

An assembly includes first and second members connected via a connector that is axially insertable into a channel defined by passages of the first and the second member. The connector exhibits a length extending in a longitudinal direction of the channel and includes first and second expansion blocks, and one or more than one wedge between the first expansion block and the second expansion block, and is configured to be displaced longitudinally relative to the channel to thereby radially expand the connector relative to the channel. At a cross section halfway the length of the connector, a cross sectional area and a height of a first expansion block in a radial direction relative to the channel is smaller than a cross sectional area and a height of a second expansion block in said radial direction relative to said channel. A method of assembling such an assembly.

A bolt arrangement for connecting at least two mechanical elements. The arrangement providing a bolt including an outer circumferential peripheral surface extending in a longitudinal direction of the bolt, a sleeve presenting an outer circumferential peripheral surface and an inner circumferential peripheral surface extending in a longitudinal direction of the sleeve between a first and a second axial end of the sleeve. The inner peripheral surface provides a tapering profile in its longitudinal direction. A portion of the outer peripheral surface of the bolt provides a corresponding tapering profile matching the tapering profile of the inner peripheral surface of the sleeve. The sleeve further provides a portion extending radially outwards at one of the first and second axial ends. In addition, a coupling arrangement is disclosed.

An adapter for anchoring an object to an existing support structure comprises: a securing block comprising a first inner block, a second inner block complementary to the first inner block, the first and second inner blocks defining a channel therethrough when placed in opposition for receiving and securing to the existing support structure, the first inner block comprising a first securing means and the second inner block comprising a second securing means; and an outer sleeve for coupling to the securing block, having: an opening to receive the existing support structure; a sleeve channel for receiving the securing block; and an attachment arm attached to an outer surface of the outer sleeve for anchoring the object.

A linear drive assembly having a linear drive motor having a shaft, the shaft defining a first bore therein extending from the first end of the shaft, the shaft defining a tapering within the first bore, and the shaft defining a second bore therein connected with the first bore and extending to the second end of the shaft; a screw including a tapered end at the first end of the screw, the tapered end configured to substantially mate with the tapering within the bore, and the screw defining a threaded bore extending from the tapered end at least partially along a longitudinal axis of the screw; and a retaining screw having a head portion and a threaded portion, the threaded portion configured to extend through the second bore and mate with a threaded bore of the screw when the screw is mounted within the shaft.

A mechanical shaft insert/outsert apparatus and method has a receiver and a wedge where the wedge has a first dimension and a second dimension where the second dimension is larger than the first dimension wherein the receiver and wedge are configured to connect with a shaft. An extension configured to connect with the receiver and the wedge such that the connection draws the wedge and the receiver together causing the receiver to deform and contact the shaft.

A composite tube assembly may comprise a composite tube comprising a variable diameter portion comprising a first frustoconical portion and a second frustoconical portion, wherein a diameter of the composite tube at an interface between the first frustoconical portion and the second frustoconical portion is a maximum diameter value with respect to the first frustoconical portion and is a maximum diameter value with respect to the second frustoconical portion, a locking wedge disposed at least partially around a circumference of the first frustoconical portion, a locking collar nut disposed at least partially around a circumference of the locking wedge, and an end fitting disposed at least partially around a circumference of the second frustoconical portion, wherein the end fitting is coupled to the locking collar nut, wherein the first frustoconical portion and the second frustoconical portion comprise a metallic insert.
