Abstract: A wheel converting mechanism for a child vehicle having a wheel includes an elongate body having a first portion, a second portion, and a third portion, wherein the third portion of the elongate body is configured to be coupled to the wheel of the child vehicle. The first portion and second portion are coupled together through a pivot joint that allows the second portion to pivot relative to the first portion about a pivot axis defined by the pivot joint. Additionally, the second portion and the third portion are coupled together through a swivel joint that allows the third portion to rotate relative to the second portion about a swivel axis defined by the swivel joint. A method of moving a wheel of a child vehicle is also disclosed.

Abstract: The present invention relates to methods of detecting an increased likelihood of virus infection in a subject. In particular, the present invention relates to methods of detecting an increased likelihood of virus infection in a subject by detecting an altered level of at least one microRNA (miRNA), as well as methods of treating or preventing virus infection. The present invention also relates to nucleotide arrays, oligonucleotides and kits useful for the detection of miRNAs associated with an increased likelihood of virus infection in a subject.

Abstract: A foldable tricycle includes a first frame, a second frame movably coupled to the first frame, and a seat for supporting a rider, wherein the seat operates as an actuator for moving the first and second frames relative to each other. Additionally, a method of handling a foldable tricycle movable between a first position and a second position includes applying a force to the seat of the tricycle, wherein the applied force on the seat causes the tricycle to move from the first position to the second position.

Abstract: An assembly for use on a wellhead includes a tree body including an internal main bore arranged in use to be aligned with the bore of a wellhead housing; the tree body including a lateral bore extending through the tree body from the internal bore; the tree body further including means for connecting to a connector so as to align the internal bore of the tree body with an internal bore in the connector, in use the tree body and the connector together forming a horizontal tree. The tree body may include one or more integrally formed bores and valves to provide fluid flowpaths for the annulus and/or cross-over functions. A wellhead assembly including the tree assembly is also provided.

Abstract: A method of manufacturing a flow block for use as a T-Block, tree block, manifold block or valve block, the method including: machining a main bore in a body; forming an opening in the body in a side wall of the main bore; providing an insert including a first bore intersecting with a second bore and being in fluid communication with each other; forming a substantially curved surface on at least part of the intersection between the first bore and the second bore; and inserting the insert into the opening, such that the first bore is substantially aligned with the main bore in order to provide a fluid flow path between the main bore and the second bore.

Abstract: A multiple envelope control system and method expands the operating capabilities of a lift vehicle. The vehicle includes a platform mounted to a telescoping main boom. The main boom is configured for lift/lower function and telescope function. The multiple envelope control system includes a selector switch for selecting between a plurality of capacity modes including at least a low load mode and a high load mode. A plurality of sensors are strategically positioned on the main boom to cooperatively define position zones of the platform. A control system determines in which position zone the platform located according to signals from the plurality of sensors. The control system controls an envelope of the platform based on a position of the selector switch. By strategically positioning the sensors to define the position zones, inexpensive switches, such as limit switches or the like, can be used, thereby reducing manufacturing costs of the machine.

Abstract: A boom lift vehicle includes a tower boom pivotally coupled at one end to a vehicle base for tower lift function and rotatable relative to the vehicle base for swing function. A main boom is pivotally coupled to an opposite end of the tower boom for main lift function. A tower boom elevation angle is defined as a maximum allowable tower boom angle relative to the vehicle base for transport. When the tower boom is below the tower boom elevation angle, the main boom angle relative to gravity is maintained at a set point angle, which is determined as the main boom angle (1) at the start of the swing function or vehicle drive, or (2) at a conclusion of the main lift function when combined with at least one of the swing function or vehicle drive. Additional control of the tower boom is effected when the tower boom is above the tower boom elevation angle.
