Abstract: WARDLY OF THE SPRAY WHEREBY THE HEAD IS MAINTAINED IN A COAXIAL POSITION RELATIVE TO THE PIPE AS IT IS DRAWN THROUGH THE LATTER.
DISCLOSED IS A MOTOR DRIVEN DRUM FOR DRAWING A SUPPLY HOSE AND AN APPLICATOR HEAD THROUGH A PIPE. THE HOSE COMMUNICATES THROUGH THE DRUM WITH A RESERVOIR CONTAINING COATING MATERIAL AND SUPPLIES THE LATTER TO THE APPLICATOR HEAD FOR COATING THE WALL OF A PIPE. THE APPLICATOR HEAD HAS A PLURALITY OF NOZZLES MOUNTED FOR ROTATION UNDER CENTRIFUGAL FORCE TO PROVIDE A CONICAL SPRAY FOR APPLYING THE COATING TO THE WALL AS THE HEAD IS DRAWN THROUGH THE PIPE. A PLURALITY OF CENTERING VANES ARE CARRIED AT CIRCUMFERENTIALLY SPACED POSITIONS ABOUT THE HEAD AND ARE SPRING BIASED TO ENGAGE THE INNER WALL FOR-

Abstract: A modular ladder assembly includes at least two ladder assemblies, each assembly having first and second parallel stiles and a plurality of spaced apart rungs disposed between the first and second stiles, the plurality of rungs being perpendicular to said first and second stiles. The first stiles of the at least two ladder assemblies are mechanically connected together and at least one adjustment assembly is mechanically connected to the second stile of one of the at least two ladder assemblies and a second end of at least one adjustment assembly is mechanically connected to a second stile of a second of the at least two ladder assemblies so that the at least two ladder assemblies and the at least one adjustment assembly have a triangular shape when viewed from a plane perpendicular to the first and second stiles of the at least two ladder assemblies.
