Abstract: A floor finishing machine includes a base frame, a movable frame movably mounted to the base frame, and a plurality of floor finishing units carried by the movable frame, and being pivotable about a generally longitudinal pivot axis and a generally transverse pivot axis. The machine may also include a jack operatively coupled between the base frame and the movable frame, and a vacuum tank carried on the movable frame and straddling the jack.

Abstract: A floor finishing apparatus includes a chassis, a housing pivotably mounted to the chassis and having a mounting surface and at least partially defining a chamber, and a plurality of floor finishing units mounted to the mounting surface of the housing. The apparatus may include a rolling device carried by the housing and adapted to contact the ground to assist the housing in being pivoted with respect to the chassis.

Abstract: The system for providing calling party privacy during subscriber call screening for a central office switching system enables a subscriber to monitor and intercept the last forwarded, active call to the Voice Messaging System, while providing the calling party with privacy as the voice messaging system provides the prerecorded instructions/message to the calling party. The calling party privacy feature delays call screening alerting to the subscriber to prevent the subscriber from monitoring the call connection until the calling party is recording their message on the voice messaging system. Depending on the method used, once the calling party privacy feature requirements are satisfied, the subscriber call screening system notifies the subscriber of the presence of a calling party who is recording a message for the subscriber on the Voice Messaging System.

Abstract: A solid-steel anvil of symmetrical configuration, having a top head, depending intermediate web and a base, and with the anvil being of light weight that a person can manipulatively grasp the anvil's top head with one hand to easily carry the anvil with his grasping hand, is produced by the method of providing a rectilinear elongated section, appropriately disposing the elongated section preparatory to successive cross-cuttings of the section, and cross-cutting successive lengths from the section to thereby provide a plurality of separate anvils.

Abstract: Processes are disclosed for recovery and purification of dibasic aromatic acids from waste polyester film, fiber, bottles, manufacturing residues, and other manufactured articles. The processes comprises: depolymerization of polyester resin in a molten polyester resin containing solvent with superheated stem, and vaporization of the aromatic carboxylic acid and other volatile products of hydrolysis to obtain a vaporized mixture containing aromatic acid, dihydric alcohol, other volatile products of hydrolysis, and water. This vapor mixture is, advantageously, substantially free of less volatile and non-volatile impurities including metals, and many colored and color causing compounds, which are, typically, found in post-consumer polyester resins.
