Abstract: A vehicle window assembly includes a cap that includes a rooftop section, which extends in a transverse direction of the vehicle, and a side wall that extends from the rooftop section generally in a normal direction. The side wall includes an opening. The window assembly also includes a rigid window that includes an interior surface and an exterior surface. Moreover, the window assembly includes a pivot coupling that pivotally connects the window to the cap for rotational movement between a closed position and an open position. The window covers the opening and the interior surface is operable to face the vehicle passenger compartment when the window is in the closed position. The window overlaps the rooftop section and the exterior surface faces the rooftop section when in the open position.

Abstract: A tubing rotator assembly that attaches to a casing head to suspend and rotate a tubing string in an oil well. The tubing assembly includes a rotation surface, such as a bearing, in which a tubing mandrel rests and allows one to rotate the tubing manually above the wellhead, and a mandrel bowl that rests inside the casing head. A tubing mandrel is partially contained within the mandrel bowl with one end exiting the bowl and attached to the tubing string, and the opposite end exiting the top of the bowl. A ledge of the tubing mandrel is supported on the bearing, which bearing rests on the interior ledge of the mandrel bowl. The assembly provides a low profile reducing the distance between the casing head and the pumping tee to eliminate the need to raise the pumping unit to fit on the rotator.

Abstract: The present invention relates to a tubing rotator assembly for attachment to an existing casing head for purposes of suspending and rotating a tubing string in an oil well. In the preferred embodiment, the tubing assembly includes a rotation surface, such as a bearing, in which a tubing mandrel rests and allows one to rotate the tubing manually above the wellhead. It provides a low profile reducing the distance between the casing head and the pumping tee, which may eliminate the need for one to raise the pumping unit to fit on the rotator. In addition, the conventional seals above the rotation surface have less chance of leaking fluids located between the casing and tubing due to the seals potentially installed in the present invention. In addition, if the conventional seals do start to leak, then one can change the packing rubber without having to remove the tubing rotator assembly or tubing string (thus, not requiring a rig to change the sealing elements).

Abstract: A portable machine for carbonating liquid contained in a bottle is adapted to support the bottle (5) by the neck (81) through a bayonet connection and for a seal (64) which closes the bottle neck to be driven into engagement with the bottle neck by a piston (60) actuated by the first burst of gas supplied to the injection nozzle (66). The bottle is loaded into the machine through a front opening (6) and a cover (7) for closing the opening is interlocked with a gas supply valve (12) so that gas can only be delivered to the nozzle (66) when the cover is closed. The cover is opened and closed by rotating a knob (23) which is depressed to open the gas valve. The knob (23) is coupled to the gas valve (12) through a device (27) which prevents the valve being opened if the machine is tilted at more than a given angle to the upright position.
