Abstract: Described herein are coiled tubes with improved and varying properties along the length that are produced by using a continuous and dynamic heat treatment process (CDHT). Coiled tubes can be uncoiled from a spool, subjected to a CDHT process, and coiled onto a spool. A CDHT process can produce a “composite” tube such that properties of the tube along the length of the tube are selectively varied. For example, the properties of the tube can be selectively tailored along the length of the tube for particular application for which the tube will be used.

Abstract: A lens and/or a view screen of an electronic device having at least one case can be cleaned by wiping the view screen with a cleaning component wherein the cleaning component is configured to selectively couple to the at least one case or some other substrate using a magnetic attractive force. The cleaning devices may have secondary applications such as securing fly fishing lures, activating or deactivating a device having a magnetic switch, or preventing sunglasses from sinking. They may also be manufactured without a cleaning component for use with the secondary applications.

Abstract: Embodiments of the present disclosure are directed to coiled steel tubes and methods of manufacturing coiled steel tubes. In some embodiments, the final microstructures of the coiled steel tubes across all base metal regions, weld joints, and heat affected zones can be homogeneous. Further, the final microstructure of the coiled steel tube can be a mixture of tempered martensite and bainite.

Abstract: The disclosed manufacture method for a length of tubing can produce a length of fatigue resistant tubing that has relatively high fatigue resistance and relatively low strip-to-strip welding length. The Fatigue resistance is calculated from experimental settings with controlled parameters and/or simulations reproducing similar material properties and loading conditions. A high fatigue resistance means certain product characteristics (e.g., low plasticization, low hydrostatic stress levels and free of imperfections welds) can be retained with an adequate bias weld design at low values after a specific test number of cyclic loading. The relatively low strip-to-strip welding length is an advantage for reducing probabilities of having cracks initiated and/or propagated at weld locations, where imperfections and localized differences of mechanical properties commonly cause failure. Low strip-to-strip welding length can also reduce the costs for welding.

Abstract: A baby stroller for transporting an infant at speeds faster than normal walking is disclosed. This baby stroller can be folded to make it easier to stow and transport. The folding mechanism, a unique feature of the design is directed toward compactness, ease of use, reliability, and reduction in manufacturing costs.

Abstract: A trailer with a protective enclosure, or roll cage, for a baby stroller frame with a seat. The trailer includes left and right wheels, a trailer frame, and a towing arm for connecting the trailer to a bicycle. The trailer frame has a bottom frame, front frame, and rear frame with each frame having a plurality of frame members that form a protective roll cage for a stroller frame mounted in the trailer frame. A stroller frame can be inserted into the trailer frame, without being modified or adapted, and secured within the trailer frame for towing.
