Abstract: A well seal and split packer for a well seal. The well seal includes a split packer having interconnecting lips to allow the packer to be slipped around one or more installed drop pipes while providing an essentially leakproof seal after installation without the use of adhesives or adhesive-type flexible sealants.

Abstract: Process for replacing a cartridge in a housing of a freeze proof hydrant. A plunger within the cartridge is urged against a roller pin lodged in the cartridge. A first end of the cartridge is deformed away from a ridge in the housing. The cartridge is slid out of the housing and the first end of the replacement cartridge is deformed. The replacement cartridge is slid into place within the housing. The first end of the replacement cartridge expanded to capture the ridge in the housing.

Abstract: Freeze-proof hydrants having a housing, the first end thereof having a fitting for flow communication with a pressurized liquid source. There is a passageway in the housing for liquid flow, a back flow preventer in the passageway and a drain in the housing. A removable cartridge is located in the passageway between the back flow preventer and the first end of the housing. The cartridge has a casing having a passageway therein, a drain therein with a drain channel and at least one hole in the drain channel which extends through the casing, arrangement for retaining the removable cartridge in the passageway, and a plunger in the passageway which can be moved from an open or liquid flowing position to a closed or liquid draining position, and vice versa. The plunger has a plunger head which blocks the passageway in the closed position and which allows liquid flow in the passageway in the open position.

Abstract: A flashlight holder includes a C-shaped clamp that holds a flashlight by friction. The clamp is attached by an angled arm to a tripod that supports the arm in a fixed position of choice. Magnet assemblies in the legs of the tripod are mounted so as to swivel, allowing the flashlight holder to be secured by magnetic force to a ferromagnetic surface. The flashlight holder is preferably made of low-density polypropylene, which is both inexpensive to buy and easy to mold in molds that require little or no relief. The angled arm makes it easy to set a flashlight at any orientation with respect to an iron or steel surface to provide light to work on car and truck engines and the like.
