摘要： An inspection device for use in scanning the interior of a pipe at a remote location is accurately centered within the pipe at the required location by two spiders. Each spider has three sickle-shaped arms which can be extended and retracted between operative and inoperative positions. The six spider arms are interconnected by a crank mechanism which ensures that all the arms move in unison between their limit positions.

摘要： A multi-use projectile launching apparatus that includes a single piece body and attached elastic propulsion band to propel an object through a portion of the single piece body. The single piece body consists of a handle for supporting the apparatus, a projectile tube through which the propelled object travels, a funnel for receiving the propelled object and passing it to the projectile tube, and one or more attachment nodes for connecting an elastic propulsion band to the single piece body. Together these components form a device capable of launching several kinds of projectile objects at high speed by propelling the projectile object with elastic force.
