Abstract: An apparatus and method for joining pipes includes a plate for melting mating surfaces of the pipes to be joined. Additionally, the apparatus utilizes a vacuum in order to push the first and second pipes together in lieu of hand or mechanical pressure which may be inconsistent. Additionally, the vacuum allows the pipes to be joined to settle on each other in order to create a pressure about a periphery of the end of the pipe being joined to the other pipe. The consistent pressure creates a very strong joint between the first and second pipes.

Abstract: An electrical power unit is positionable in or along a work surface and includes a housing with a movable cover that is positionable in open and closed positions at an upper region of the housing. The cover defines an interior region in which a wireless power transmitter is mounted. A lamp unit is disposed in the housing or the cover.

The wireless power transmitter is operable to selectively illuminate the lamp unit when the wireless power transmitter is energized. Optionally, at least one direct-contact electrical or data receptacle is provided at the housing, and may be arranged or positioned so that it is accessible at least when the cover is in the open position.
