Abstract: An apparatus is provided for the attachment of brushes to the drive system of rotary floor scrubbing machines. In one embodiment, the apparatus provides for a scrubbing plate assembly suitable for attachment to the drive system of a rotary floor scrubbing machine. The scrubbing plate assembly has a scrubbing plate and an adapter plate. When the adapter plate is aligned and in contact with a scrubbing plate, the adapter plate locks to the scrubbing plate by axial movement of said adapter plate relative to said scrubbing plate.

Abstract: A push broom head is provided having a substantially rigid base, leading edge, upper and lower surface, central vertical axis, plurality of rows of seats, and a plurality of tufts of bristles. The head includes a leading edge row(s) of tufts of a first type closest the leading edge and a plurality of rows of a second type. The length of the second type of tuft bristles is longer than the length of the first type and the number of rows of tufts of the second type exceeds the first type. The axis of each tuft forms an angle relative to the base's central vertical axis. Preferably, when not in contact with the sweeping surface, the angle of attack of the second type of bristles differs by row and/or the angle of the leading row of tufts exceeds 10 degrees in a forward direction relative to the central vertical axis.

Abstract: A food and beverage dispenser with a dispenser lid and a dispenser body. The dispenser body has four walls and a bottom. The dispenser lid seats on the dispenser body. The dispenser lid is secured to the body by cooperation of the lid with the body. Rotation of the lid causes a seal bead on the lid to seal against a seal bead on the body. The dispenser lid is a polyethylene shell, and the seal bead on the dispenser lid is an elastomeric gasket secured to the polyethylene shell.

Abstract: The food pan carrier has a pan carrier body and a pan carrier door. The pan carrier door is slidable relative to the pan carrier body from an open to a closed position. When the door is in the closed position, the food pan carrier will maintain food that has been heated to at least 185° at a minimum of 141° for an extended period of time. The pan carrier body has grooves in which the food pan door is received. The food pan door preferably has rails that are slidable in the grooves. The door slides in the grooves from a second end to a first end of the grooves. As the door slides from the open to the closed position, it moves toward a sealing surface that circumscribes an opening through which food pans are inserted and removed from the pan carrier body. In the fully closed position, the door sealingly engages the sealing surface that circumscribes the opening through which food pans are inserted and removed.

Abstract: A floor sign comprising two substantially similar panels and an engaged slidable locking bar. Each panel has a pair of closely spaced apart tabs with an aperture through each and a tab having a boss on both sides. The two panels engage each other at their upper end by interlocking the pair of tabs with the tab bosses. The upper portions of the panels are pivotably coupled. The locking bar has an upper horizontal section and a vertically depending section and is inserted between the two panels for maintaining the panels in a spaced apart deployed position or in a collapsed position. The floor sign is deployed by pressing downward on the locking bar to insert the bar between the panels, forcing them apart at a ridge on the inner face of each panel. The bar locks to maintain the lower ends of the panels in a spaced apart configuration. To collapse the sign a user lifts upward on the locking bar via a notch in the panels to release the locking bar and permit the panels to collapse toward each other.

Abstract: Methods and compositions are provided for making low temperature sintering ceramic bodies that have very low thermal expansion and low porosity.
