International Classification:

B60D 1/02

US Classification:

280515, 280504

Abstract:

A trailer hitch system for equalizing trailer loads and reducing trailer sway. The trailer hitch system may include spring bars that may be attached to a hitch head using a trunnion style connection. The spring bars may be attached to the trailer using rigid brackets that reduce swinging of the spring bars. The rigid brackets having a plurality of contact points may include an upward extending portion for attaching to the trailer tongue, and a lateral extending portion for receiving the spring bars thereupon. The rigid brackets may include a spacing member and an attachment member.

US Classification:

254423, 2807631, 254424, 29428

Abstract:

A system for supporting a vehicle. The system may include a vehicle jack in mechanical communication with a jack foot and a striker plate. The jack foot is rotatable relative to the vehicle jack on a rotation axis disposed on the vehicle jack and perpendicular to a long axis of the vehicle jack. The jack foot includes a base at a distal end of the jack foot. The jack foot also includes a cam surface at least in part at a proximal end of the jack foot. The cam surface is aligned with the striker plate and interacts with the striker plate to rotate the jack foot in response to movement of the vehicle jack from a lowered position to a raised position.

Abstract:

The present invention generally relates to a low temperature plasma probe for desorbing and ionizing at least one analyte in a sample material and methods of use thereof. In one embodiment, the invention generally relates to a low temperature plasma probe including: a housing having a discharge gas inlet port, a probe tip, two electrodes, and a dielectric barrier, in which the two electrodes are separated by the dielectric barrier, in which application of voltage from a power supply generates a low temperature plasma, and in which the low temperature plasma is propelled out of the discharge region by the electric field and/or the discharge gas flow.
