摘要： Foam generating equipment for use in mines includes supply vessels for the resin and foaming agent located in a central stores location. An air compressor is also located there. A pair of pumps in a protective casing transportable by an operator have inputs receiving the resin and foaming agent and outputs connected to a foaming gun. The pumps have a common power supply connection coupled to the air compressor. The pumps in the casing are carried by the operator and deposited at a temporary location in proximity to the site where the foam is to be emplaced. The spray gun is then operated to emplace the foam at the site.

摘要： An adjustable mounting and driving device is disclosed for a polygonal mirror to be mounted on a drive shaft. The mirror is held at an axial end in a cup shaped cavity in a holder having a central bore for receipt of the drive shaft. The bore has a drive shaft contact area which is relatively axially short allowing the housing to tilt on the drive shaft. A plate is fixably mounted on the drive shaft axially adjacent the holder and has a plurality of axially adjustable set screws engageable with a back wall of the holder to control tilt of the holder on the shaft. A resilient member between a front wall of the housing and an extension of the plate urges the housing into contact with the set screws and rotatably drives the mirror.
