Abstract: A fish hook assembly that includes a substantially hemispherical or polyhedron head with an eye and a weed guard extending from the head. A round bead is in physical contact with at least the weed guard so that underwater obstructions that would normally get snagged on the eye and/or weed guard will roll away over the bead.

Abstract: A fish hook assembly that includes a rounded bead affixed in the notch between the eye of the hook and an intermediary object, such as a weed guard, fish attractor component, weighted head, or bend. Underwater obstructions that would normally get snagged in the notch will roll away over the bead.

Abstract: The present invention is a leak detection and location system that includes a waterproofing membrane; an underlayment disposed directly below the waterproofing membrane, wherein the underlayment is non-conductive and will become conductive only when saturated; a conductive layer disposed below the underlayment; a voltage source attached to the upper side of the waterproofing membrane and the lower side of the underlayment; a test set with two handheld poles and an indicator that indicates a difference between voltages detected by the handheld poles; and a device that creates an electrical field across the waterproofing membrane.

Abstract: The system of the present invention is used for detecting and locating leaks in a roofing envelope that includes an insulation package. The system includes at least two contacts disposed within the roofing envelope, where at least one contact is active and at least one is passive. The active contact is capable of emitting an electric signal of a known voltage, and the passive contact is capable of reading voltage at the location of the passive contact. All contacts are in electrical communication with a computer.

Abstract: The present invention is a method and system for detecting and locating leaks in a roofing membrane. The mean net voltage from an emitting electrode activated by and connected to the positive side of a power supply, when a conductive mesh disposed beneath the membrane is connected to the negative side of the power supply, is compared with the mean reference voltage from the emitting electrode when a reference electrode is connected to the negative side of the power supply in place of the conductive mesh. If the mean net voltage is greater than or equal to the mean reference voltage, then a leak is indicated.

Abstract: A system for detecting and locating a leak through a membrane that includes a detector array, a signal generator, a flexible sheet over-membrane, a conductive felt, and a computer. The detector array includes a boundary wire loop and sensors. The signal generator applies voltage to the boundary wire loop. The conductive felt is applied on top of the detector array.

Abstract: A system for detecting and locating a leak through a membrane that includes a detector array and computer. The detector array includes a boundary wire loop, sensors, and leads. The boundary wire loop surrounds the area to be tested and generates electrical tension on the surface of the membrane. The sensors are laid out in a sensor array and are placed on top of a membrane and within the boundary wire loop. The sensors are encased in a plastic covered cable or individual wires which have open ends for their terminations forming a cable so that the sensors made by the open terminations form a chain. Each sensor communicates individually with the computer and the signals from the sensors are used by the computer to perform vector mapping that detects and locates leaks through the membrane.

Abstract: A concrete barrier having a plastic cladding that provides protection for the concrete against chemical deterioration. A cap assembly enables the barrier to be fitted with standard anchor sheets and made in standard jersey barrier forms. The cap assembly has a large radius so that anchor sheets can be easily bent and will fit snugly within the form to prevent wet concrete from leaking between the anchor sheet and the form. The invention can be used with all standard jersey barrier forms, both horizontal and upside-down type, for either full or half barriers.
