Abstract: A collapsible golf cart comprises a frame member, a handle, and a carriage. The handle is pivotably coupled to the frame and the frame is pivotably coupled to the carriage. The carriage has a pair of front wheels and a pair of rear wheels. The golf cart is moveable between an extended configuration in which corresponding ones of the front wheels and rear wheels are offset with respect to one another, and a collapsed configuration in which corresponding ones of the fronts wheels and rear wheels are substantially aligned with respect to one another.

Abstract: A golf cart including a frame having a first portion and a second portion. A front wheel mount is pivotally connected to the first portion of the frame and is pivotable about a first axis. A front wheel is rotatably connected to the front wheel mount, allowing for rotation of the front wheel about a second axis that is generally perpendicular to the first axis. The front wheel mount further allows for arcuate movement of the front wheel about the first axis. There is a pair of rear wheel members, each rear wheel member having a first end and a second end, the first end of each rear wheel member is pivotally connected to the second portion of the frame. There is a pair of rear wheels, each rear wheel is rotatably connected to the second end of one of each of the rear wheel members. A handle is connected to the second portion of the frame. A collapsing mechanism is moveable between a first position and a second position.

Abstract: An articulated seal for use with polished rod and rotary drive head assemblies is described. In particular, an articulated seal assembly or system 10 is described which seals a rotating drive head and polished rod between high pressure internal fluids within a well 12 and the exterior while absorbing the normal wobble motion of a rotating polished rod.

Abstract: An insertable progressing cavity pump is taught. The pump is insertable in a bore of a tubing string by carriage on a drive string, the insertable progressing cavity pump includes a stator, a helical rotor locatable in the stator and including a coupling for connection to the drive string, a tubular housing for accommodating the stator therein and sized to be insertable into the tubing string, a pump hold-down arrangement in communication with the housing and disposed above the stator for engaging the pump into the tubing string, and a torque transmitting arrangement acting between the rotor and the housing to transmit torque from the rotor to the housing in both the clockwise and counter-clockwise direction, when the housing is carried on the drive string. The insertable progressing cavity pump in another aspect includes a hold down assembly disposed above the stator on the pump housing.
