The present invention is directed to a porous concrete system comprised of a porous concrete slab and one or more cast-in conduits, with at least one conduit including an adapter capable of connecting to a hose. In addition, the present invention is also directed to a porous concrete system comprising a plurality of porous concrete slabs, wherein each porous concrete slab contains one or more conduits embedded therein and at least one conduit in each porous concrete slab has an adapter that is connectable to a hose and wherein the porous concrete slabs are arranged in a manner where the conduits in one porous concrete slab are adjacent to the conduits in the neighboring porous concrete slab.

Coaxial video push-cables are disclosed. One embodiment includes a central conductor and a multi-dielectric stack of multiple concentric tubular layers disposed around the central conductor having one or more structural layers and one or more impedance tuning layers where the thickness of materials of each layer are selected to provide a pre-defined elastic modulus and electromagnetic impedance, an electromagnetic shielding layer, and a jacket enclosing the shielding layer, multi-dielectric stack layers, and central conductor.

An integrated enhanced water faucet system comprising a faucet assembly and a water treatment assembly; wherein the faucet assembly comprises a multi-channel hose fluidly coupled to a spray head, and a valve cartridge configured to control flow of untreated water; and the water treatment assembly comprises an enhanced water generator and a treatment valve associated with a treatment valve actuator; and wherein the valve actuator is configured to open and close the treatment valve, the system is configured to deliver enhanced water upon actuation of the treatment valve, and untreated water and enhanced water are configured to be delivered to the spray head via separate channels of the multi-channel hose.

The process of forming a blowable flexible innerduct contains the steps of forming an inner innerduct structure comprising at least one inner longitudinal chamber, where the at least one inner longitudinal chamber comprises an inflatable tube and forming a textile. Concurrently forming an outer innerduct structure from the textile having at least one outer longitudinal chamber and inserting at least one inner longitudinal chamber into at least one of the outer longitudinal chambers. The inflatable tube has a wall thickness of less than about 0.5 mm. The inner longitudinal chamber alone has an air permeability of less than about 1 cfm, outer longitudinal textile chamber alone has an air permeability of greater than about 100 cfm, and the outer and inner longitudinal textile chambers together have an air permeability of less than about 1 cfm.

Tubing bundle supports comprise body parts clamped around split rotatable sleeves. In one embodiment, spring mounted peripheral shoes and rotatable tubing bundle support sleeves allow metal tubes and tubing bundles to be routed inside a conduit in spaced apart positions and resistant to vibration. In another embodiment, split pillow block sections are clamped around a split rotatable sleeve. In an embodiment, the split pillow block support is held to a strut channel by a strut channel nut.

A line connector with two mutually separate flow paths for the connection of a pipe-in-pipe line. The line connector has an inner connecting element for connecting to an inner pipe of the pipe-in-pipe line, an outer connecting element for connecting to an outer pipe of the pipe-in-pipe line, a first attachment element for attachment of the first line to the inner pipe, and a second attachment element for attachment of the second line to the outer pipe. The inner connecting element and the first attachment element are integrally formed on a separate attachment part. The outer connecting element is integrally formed on a separate pipe adapter part. And, the second attachment element is integrally formed on a separate connecting sleeve. The connecting sleeve permits at both sides, in the unassembled state, being pushed over the outer pipe. The invention also relates to a line set including the line connector.
