Abstract: A valve lock has a body and a moveable jaw for releasably gripping a lever handle of the valve against the body. The jaw has a threaded shaft that extends through a hole in the body, and a locking cleat is slidable on the threaded shaft. An arm is attached to the shaft between the body and the locking cleat, and is rotatable about the shaft to abut either the valve or a pipe connected to the valve. A hand wheel is threaded onto the shaft and can be tightened against the locking cleat which then forces the arm against the body to inhibit rotation of the arm about the shaft. The locking cleat has an aperture for receiving the shackle of a padlock, and the hand wheel has a plurality of notches in an exterior surface with one of the notches receiving the shackle to restrict movement of the wheel along the shaft.

Abstract: A tooth flossing device for making the task of flossing teeth easier, neater, and more effective. A handle, designed for being gripped by a hand of a user, carries a removable, replaceable cartridge attached to one end. This cartridge contains a length of dental floss stretched between two pole pieces which are just far enough apart to pass a tooth between them. A user inserts the cartridge end of the flosser into his mouth, pressing the length of floss between two adjacent teeth, repeating the action until the spaces between all teeth have been cleaned. A used cartridge can be quickly and easily removed from the handle and replaced by a new one by pressing a detent and sliding the old cartridge from engagement with the handle. When the fresh cartridge is inserted, the detent automatically locks it into position.

The carrier (10) includes an enclosure (16) comprising forward and rearward side walls (18 and 20, respectively), and opposite end walls (20 and 24), and a bottom portion (26). The enclosure (12) is divided into a refrigeration housing (28) and a tool compartment (30) with a partition (32). Further, means are provided for releasably mounting the carrier (10) across the bed of a pickup truck (14). The carrier (10) further comprises a refrigeration unit (70) slidably received within the refrigerator housing (28), the refrigeration unit (70) defining a refrigeration compartment (71) for carrying items to be refrigerated. A door assembly is also provided for selectively accessing either the refrigerator housing (28) or the tool compartment (30).
