A powered converter trolley for movement and attachment of trailers is provided. The trolley comprises a conventional converter trolley having a drawbar. The trolley has a power supply and operates as a towing device. The trolley connects to a freight trailer and can be raised or lowered from a stored position to a ground-engaging, working position. Alternatively, the wheels of the trolley may be powered for providing motion to the trolley. The trolley further comprises several attachment devices for securing the trolley to an intermodal railcar, including alternative hydraulic, mechanical, and electrically-powered tie down devices. A trolley movable along a railcar is provided for securing the trolley or trailer to the railcar and includes a hitch component for selectively interconnecting to a hitch component on the trolley or trailer.

The intervertebral disc is avascular. With aging, calcified layers occlude the capillaries at the cartilaginous endplates, reducing diffusion of nutrients and oxygen from capillaries into the avascular disc. Under anaerobic condition, excessive production of lactic acid decreases intradiscal pH and irritates surrounding nerves, causing persistent back pain. Antacid is injected into the painful disc to increase pH and alleviate back pain.

A powered converter dolly for movement and attachment of trailers is provided. The dolly comprises a conventional converter dolly having a retractable landing gear assembly mounting wheels attached to the drawbar. The dolly has a power supply and operates as a towing device. The landing gear assembly provides steering for the dolly as well as motive power from a motor connected to the landing gear wheels. Alternatively, the wheels of the dolly may be powered for providing motion to the dolly. The dolly further comprises several attachment devices for securing the dolly to an intermodal railcar, including alternative hydraulic, mechanical, and electrically-powered tie down devices. A trolley movable along a railcar is provided for securing the dolly or trailer to the railcar and includes a hitch component for selectively interconnecting to a hitch component on the dolly or trailer.

An exercise device has a two-part telescoping elongate bar with a first rod and second rod. The first rod includes a weighted collar affixed to each end that can hold additional weights. The second rod is received within the first rod and engages via a coupling for axial sliding movement outward from an open end of the first rod for telescoping operation such that the device is extensible. A person holds the device using hand grips attached to one end of the first rod and an opposing end of the second rod.

A rotor that includes a rotor core assembly secured to a shaft. The rotor core assembly includes a magnet and an end cap secured to an end of the magnet. Each of the magnet and the end cap has a bore into which the shaft extends. The end cap forms an interference fit with the shaft. The magnet forms a clearance fit with the shaft and an adhesive is located in the clearance between the magnet and the shaft. Additionally, a method of manufacturing the rotor. The method includes inserting the shaft into the bore of the end cap. An adhesive is then introduced into the bore of the magnet and the shaft is inserted into the bore of the magnet so as to cause adhesive to be drawn into the clearance defined between the magnet and the shaft.

A rotor core assembly that includes a magnet, a first end cap located at an end of the magnet, a second end cap located at an opposite end of the magnet, and a sleeve that surrounds the magnet and the end caps. The sleeve forms an interference fit with each of the end caps, and an adhesive is located between the magnet and the sleeve. Additionally, a method of manufacturing the rotor core assembly.

The invention provides an apparatus and a method of deploying a tubular along a predetermined path. The method includes the steps of: coiling a tubular; accommodating the tubular in a deployment unit such that at least a portion of the coiled tubular is biased radially outwardly against the deployment unit; and deploying the tubular from the deployment unit along the predetermined path. The tubular can be deployed in a fluid along a predetermined path by: independently suspending the deployment unit in the fluid; and moving the deployment unit adjacent the predetermined path and simultaneously deploying the tubular along the predetermined path. The apparatus for deploying a tubular can comprise a deployment facilitator for facilitating deployment of the coiled tubular. The tubular can be arranged to feed into the deployment facilitator in use, and the deployment facilitator can be adapted to substantially reverse the coil bend of the tubular.

An IDT connector (1) is provided which includes: a base housing (3) having a terminal (19) to which a wire (21) is press-fit; a cover housing (5) mounted to the base housing (3) and having a wire insertion hole (29) into which the wire (21) is inserted; a wire holder (31) which is provided to the cover housing, for pressing the wire that is to be press-fitted to the terminal; and an IDT contact slot extending orthogonal to the wire insertion hole and formed adjacent to the wire holder with respect to the longitudinal direction of the wire insertion hole.

A collapsible cycle for use by a rider over a terrain surface comprises a frame having front and rear portions and a seat attached to the frame. A front wheel is rotatably attached to a steering member, the front wheel rotatable in a first plane about a primary axis, and the steering member being pivotally attached to the front frame portion for rotation about a secondary axis orthogonal to the primary axis. A user-operable steering mechanism is coupled to the steering member. A rear wheel is rotatably attached to the rear frame portion and rotatable in a third plane about a tertiary axis. A drive mechanism is operatively coupled to the front and / or rear wheel. The cycle is collapsible from an erect riding configuration to a collapsed configuration by repositioning the front and rear wheels into mutually closer proximity.

The present trailer hitch assembly addresses the problem of lost tongue weight support and towing capacity when a person adds an extension to a trailer hitch for adding a slide-in camper to a truck or for moving a trailer back a little to increase the turning radius. Generally, when such an extension is utilized, the towing capacity of the vehicle to which the extension is attached is downgraded, due to the lengthening of the overall trailer hitch assembly and lack of structural support. Disclosed herein is a trailer hitch assembly that addresses this problem by providing extra structural support to boost this lack of structural support.

A card edge connector includes an elongated housing, a plurality of contacts retained to the housing, and a retainer located at one end of the housing along an elongated direction of the housing. The housing has a pair of side walls and a central slot between the side walls. The retainer has a resilient retention arm and a rigid stop arm diverging from the retention arm along a transverse direction perpendicular to the elongated direction. The retention arm has a locking section extending along the elongated direction to lock a daughter board and an operating section obliquely extending from the locking section along a third direction different from both elongated direction and transverse direction. The stop arm has an abutting section behind the operating section along a fourth direction perpendicular to the operating section to limit a deflection of the operating section.

The present invention is directed to a novel heat moldable gel and foam composition and the process for making the gel and foam composition.
