  • Patent number: 9216368
    Abstract: An apparatus for filtering and/or purifying water flowing through a water distribution system has a water filtration/purification cartridge mounted inside a housing. The apparatus provides for water boiler expansion pressure relief, while guarding against any water contaminated downstream of the apparatus backflowing into contact with the outlet side of the filtering and/or purifying matrix of the cartridge to prevent possible contamination of the outlet side of the matrix from such backflow and thereby cause water exiting the outlet port apparatus to be contaminated.

  • Patent number: 9109721
    Abstract: An apparatus for filtering water has an interface and a filtration/purification canister removably mountable onto the interface. Connecting the canister to the interface automatically opens a check valve in the interface to permit water to flow from the interface into and through the canister, and then back to and through the interface to an outlet port. Disconnecting the canister from the interface automatically closes the check valve, stopping the flow of water. The interface provides for water boiler expansion pressure relief, while guarding against any water contaminated downstream of the apparatus from backflowing into the filtration/purification canister and contaminating the portion of the filtration/purification canister downstream of the filter/conditioning/purifying medium held within the filtration/purification canister and thereby causing water exiting the outlet port of the filtration/purification canister to be contaminated.

  • Publication number: 20150047516
    Abstract: A method and system for compacting waste materials in a collection container. The container can be a freestanding waste container, a self-container compaction container, or a container on a waste collection vehicle. A hydraulically operated compactor blade is positioned in the raised upper portion of the container with its bottom edge a distance above the floor. A platform with a hinged portion can be included to divide the container volume into two separate compartments in order to collect different types of waste materials.

  • Publication number: 20140374339
    Abstract: An apparatus for filtering and/or purifying water preferably comprises a canister having filtration chamber formed therein and a matrix mounted in the filtration chamber for filtering and/or purifying water that passes through it. Shock absorbers preferably are provided for guarding against damage to the matrix if the apparatus is dropped. Preferably, the apparatus is provided with an inlet port to the filtration chamber, a first outlet port from the filtration chamber, and a second outlet port from the filtration chamber. Water may be pumped into the filtration chamber from the inlet port to wash away dirt and debris that may build up in the filtration chamber and then exit the filtration chamber with the dirt and debris via the second outlet port when open, thereby accomplishing removal of dirt and debris from the filtration chamber without having to backwash the apparatus for filtering and/or purifying water.

Connecting the canister to the interface automatically opens a check valve in the interface to permit water to flow from the interface into and through the canister, and then back to and through the interface to an outlet port. Disconnecting the canister from the interface automatically closes the check valve, stopping the flow of water. An end cap may be substituted for the canister to permit fluid to flow through the interface when the canister is not mounted on the interface. The outlet port may be directly connected to an appliance that uses water, to eliminate possible contamination that may occur when water is brought indirectly form the outlet port to the appliance instead. A flapper valve is provided in the canister to prevent back flow of fluid from the inlet port of the canister when the canister is not mounted on the interface.
