An enamel coated steel dowel bar and a method of manufacturing said enamel coated steel dowel bar for use in joining together and stabilizing concrete slabs by drilling a first hole at a first end of an axis of the dowel bar, drilling a second hole at a second end of the axis of the dowel bar, configuring a first end plug into the first hole of the dowel bar, configuring a second end plug into the second hole of the dowel bar, attaching a first end cap over the first end plug and the first hole, and attaching a second end cap over the second end plug and the second hole, wherein a pin is removably attached to the first hole and the second hole to mount the dowel bar during an enamel coating process and wherein the dowel bar is slidably attached to the first end cap and the second end cap.

Electro-active vitreous enamel coated dowel bar

A system and method for de-watering porous material, e.g., concrete. In select embodiments, durable, dimensionally stable anodes (DDAs), preferably configured as arrays on a strip, are impressed into the concrete and a pulsed signal is provided by a DC power supply to the DDAs and cathode rods inserted in soil. The DDAs comprise a valve metal substrate mesh having a semi-conductive coating of a precious metal, cement or ceramic. In select embodiments, conducting grout of a hydraulic cement-based mineral-aggregate may be used to emplace the DDAs. In select embodiments, a single cycle of the signal comprises a pulse train consisting of an initial positive pulse followed by a shorter duration negative pulse and ending with a short off period before re-cycling. The cycles continue until the porous material has been sufficiently treated.

Electro-osmotic pulse (EOP) treatment method

An Electro-Osmotic Pulse (EOP) system is used to dewater structure, both natural and manmade. Preferably, the system employs durable, dimensionally stable anodes affixed to structure in a configuration designed to maximize electrical contact with the structure and minimize electrode gas generation. The anodes and cathodes are attached to a DC power supply that provides a voltage potential between them. DC power is cycled until the structure has been sufficiently treated. Select embodiments employ perforated metal pipes as cathodes for the purpose of transport and drainage of fluids. In select embodiments of the present invention, the cathodes are connected to variable resistors designed to reduce opportunity for corrosion of buried metal objects in the vicinity of the EOP system. Select embodiments employ a pre-specified pulse train of DC voltage pulses to migrate water from under a crawl space while moving available cations in the soil. Select embodiments also protect large structures such as concrete dams.

A configuration for use with a processor that incorporates a suite of agents in a 'flat' hardware architecture and superimposes thereon a self-forming, self-healing, hierarchical architecture implemented in software. Embodiments may be employed in various applications, such as maintaining network integrity. In one embodiment a building security monitoring network provides for automated network agents to each be capable of communication with any other automated agents on a network at network startup. Shortly after network initialization, the software architecture is superimposed on the flat hardware architecture, re-arranging communication links to provide an efficient hierarchy of control and substituting working agents for compromised agents as necessary in the network. All of this is done in a 'live' network, not requiring shutdown, or even reduced operation to accomplish. This &#x201c;dual&#x201d; architecture (hierarchical software and flat hardware) provides excellent reliability in those &#x201c;layered&#x201d; network applications requiring near total reliability, such as security surveillance.

A barrier to fluid passage is embedded within, instead of atop, porous material to retain the durability of the surface of the porous material. In one embodiment, a thin set mortar is applied to a concrete slab. A pleated metal foil is pressed into the wet mortar and a bond is established. The mortar is allowed to set and a top, or finish, section of concrete is then poured over the foil and finished conventionally. Provisions are made for sealing expansion joints in concrete slab floors and at the juncture of floor and wall. The foil may be provided in multiple layers to provide a mechanical bond via mortar oozing through perforations or along pleats in each of the top and bottoms layers, while providing a solid layer through which a fluid will not pass, at least in one direction.

A system and method for dewatering particulate materials employs an improved dewatering probe generally including a single non-conducting pipe having a plurality of holes or slots, an anode mounted on the pipe adjacent one end of the pipe, and a cathode mounted on the pipe adjacent the opposite end of the pipe. The pipe serves as both a sonde for mounting the anode and cathode and as a well for extracting water that collects around the outside of the pipe and flows into the interior of the pipe through the holes or slots via gravitational and electro-osmotic forces. A pump may be used to extract both collected water and accumulated electrolytic gases from the pipe's interior. In embodiments, an array of guide electrodes is mounted on the pipe in addition to the anode and the cathode in order to deflect the major current flow out into the body of surrounding particulate materials. The guide electrodes also facilitate rapid depolarization of the probe. An array of probes according to the present invention may be employed as a system to dewater a volume of particulate.
