Abstract: A cleaning implement including a foot, a motor, and an eccentric mass. The foot has a foot plate and an oscillation plate movably coupled to the foot plate. The motor is coupled to at least one of the foot plate and the oscillation plate. The motor rotates about a motor axis extending at a non-perpendicular transverse angle relative to the surface. The eccentric mass is coupled to the motor to generate an oscillating force between the foot plate and the oscillation plate upon operation of the motor. The oscillating force has a planar component parallel to the oscillation plate and a perpendicular component perpendicular to the oscillation plate.

Abstract: Provided herein is technology relating to polymerization and producing polymers and particularly, but not exclusively, to methods, systems, and compositions for producing articles using three-dimensional printing and for improving control of polymerization using a polymerization photoinhibitor having fast back reaction kinetics such as hexaarylbiimidazole compounds and bridged hexaarylbiimidazole compounds.

Abstract: A cutting tool includes a housing, a motor positioned within the housing, a pipe holder formed in the housing, a blade pivotally coupled respective to the pipe holder at a pivot point for movement relative to the pipe holder during a cutting motion, a drive mechanism including a first gear, and a quick-change mechanism rotationally coupling the blade to the first gear. The quick-change mechanism is operable to selectively de-couple the blade from the first gear to remove the blade for replacement.

Abstract: A fastener driver includes a housing, a magazine coupled to the housing containing fasteners therein, and a nosepiece at least partially defining a fastener driving track into which fasteners from the magazine are individually received. A driver blade is movable from a retracted position toward an extended position during which a fastener in the fastener driving track is discharged from an opening in the nosepiece. A work accessory including a guide portion is configured to align an article with the nosepiece opening prior to attaching the article to a workpiece during a fastener driving operation, and a separate puller portion configured to apply a tensile force to an article to be attached to a workpiece during a fastener driving operation. The work accessory is adjustable relative to the nosepiece to selectively position the guide portion or the puller portion proximate the nosepiece opening.

Abstract: An apparatus and methods are disclosed for retrofitting a manual benchtop milling machine utilizing servo controls and/or stepper motors. The present disclosure provides a retrofit kit for the modification of a milling machine by incorporating ball screws and ball nuts without removing or replacing the original acme nuts, which inherently have been properly configured and aligned to the machine on which they were originally installed. The retrofit kit of the present disclosure allows for the modification using the alignment of the original acme nuts in their proper location and alignment obviating the need for custom machining or alignment.
