The present invention relates generally to motorized vehicles and more specifically to a three wheeled motorized vehicle providing a hybrid crossover between an automobile and a motorcycle that is able to take tight corners like a motorcycle by provision of a segment enclosing the operator that can lean into turns, The front segment contains two wheels for both steering and propulsion and is conventionally constructed like any typical front wheel drive vehicle. The rear segment contains the operator (and optionally passenger) supported on a single wheel, The two segments are joined together via a coupling that both supports the assembly and allows rotation of the rear segment about the longitudinal axis to perform the lean for operator and or passenger comfort, while transmitting critical control functions.

A payload lift and positioning system mounted to an airship for precisely positioning a payload being lowered from the airship to the ground. The payload lift and positioning system includes a support beam structure mounted to an underside of the airship, the support beam structure including load hoists and guide cable hoists mounted thereto. A payload supporting structure to carry the payload, the payload supporting structure being connected to support beam structure by the load hoists and guide cable hoists. A guide cable system includes a plurality of guide cables, each extending from the guide cable hoists disposed on the support beam structure. A positioning system includes a guide member that is mounted on the payload supporting structure to control the position of the payload being lowered from the airship to ground.

Core material is removed from a passage in a casting by exposing at least a portion of the core material in the passage to a leaching liquid. At least a portion of the core material in the passage is exposed to a gas. An opening to passage is exposed to a gas. At least a portion of the leaching liquid in the passage is boiled while the opening to the passage is exposed to a gas. At least a portion of the leaching liquid is expelled from the passage in the casting by the boiling action. To expose at least a portion of the core material in a passage to a leaching liquid, a flow of leaching liquid is conducted from a reservoir container to an operating container in which the casting is disposed. To expose at least a portion of the core material in the passage to a gas, a flow of leaching liquid is conducted from the operating container to the reservoir container.
