Abstract:
A device (10) is disclosed for biocidal treatment of vegetation and/or pests, the device (10) comprising an inner tube (30) connectable to a source of one of heated pressurised gas and heated pressurised water, an outer tube (26) disposed over the inner tube so that a space is defined between the inner tube and the outer tube, and a wand (22) in communication with the inner tube (30) and the outer tube (26). The wand (22) has an outlet aperture and the outer tube (26) is connectable to a source of the other of heated pressurised gas and heated pressurised water. The heated air and water mix in the wand (22) immediately prior to passing through the outlet aperture.
Abstract:
The antipest mat protects vehicles against entry by small animals by giving the animals a deterrent electrical shock. The mat is made up of two sections joined together to form a closed shape with an open area in the middle. The sections are connected together at a pivot point that allows the mat to be opened so that it can be placed around a vehicle support point, such as a tire, and then closed to completely surround the vehicle support point. The upper insulative surface of the mat sections holds a pattern of closely spaced conductors. The conductors are arranged so that adjacent conductors are of opposite or differing polarities. The conductors are connected to one or more connectors. A source of electric power is provided to energize the conductors so that an animal contacting two or more adjacent conductors receives an electric shock.
Abstract:
A control device for marine animals comprises an electrical device that applies an electrical voltage directly to a marine animal in order to shock the marine animal, for control thereof. The device preferably comprises a pole or rod having electrical prongs at one end which my be applied to the marine animal, thereby applying and electrical signal having a voltage, amperage and frequency that stuns and/or shocks the animal. The character of the electrical signal is such that the animal is temporarily paralyzed, so that it may be safely handled by humans for bringing it into a watercraft without otherwise damaging the animal.
Abstract:
A system and process is provided for removing or treating harmful biologic and organic substances within an enclosure, such as a container, building or vehicle. Air within the enclosure is heated to a predetermined temperature to kill organisms and cause harmful substances in the structure to migrate into the ambient air. Boric acid in combination with the heat may be used to kill mold and similar undesirable organisms. Temperature and pressure levels are monitored. The heated air carrying the harmful substances is passed through a filter to remove the harmful substances, and the heated air is re-circulated to enhance efficiency. The system effectively kills insects, molds, viruses and bacteria and reduces the levels of allergens and volatile organic compounds in the structure.
Abstract:
A non-toxic fire ant extermination system providing probe injection of scalding water below ground level within a fire ant mound is disclosed. The system includes a propane fueled water heater and water circulating pump capable of heating water in the range of 200 to 210 degrees Fahrenheit and of delivering the same at a flow rate of least three gallons per minute which is effective to eradicate the insects within the core region of a fire ant mound. The injection probe features a cylindrical capture shield which is radially disposed about the probe and adapted for sliding attachment therewith being spring-biased in a downward direction against the surface of the ground during operation thereof to retain the intense heat generated by the process,to capture fire ants emerging from the mound, and to protect the operator from the backflow of scalding water as the treatment proceeds. The injection probe is inserted below ground level and a continuous flow of scalding water is introduced into the mound as the probe is inserted further and slowly withdrawn until the hot water has penetrated throughout the core region of the mound complex. The fire ant extermination system is adaptable for use with any natural source of fresh water by use of a suitable filter system. In the alternative the system is adaptable to any municipal water supply having adequate water pressure in the range of 40 to 60 pounds per square inch.
Abstract:
A pressure regulator apparatus and method for controlling the pressure in a pressure system is disclosed. The pressure regulator broadly includes a pressure transducer and a regulator control circuit. The pressure transducer measures the pressure of the pressure system, and the regulator control circuit controls the pressure in the pressure system in response to the pressure reading of the pressure transducer. The regulator control circuit compares the measured pressure to a predetermined set-point value for maintaining the pressure within a predetermined optimal pressure range.
Abstract:
A method for thermally treating fouling infestations of macroinvertebrates is disclosed. The inventive method includes treatments of both large structures in contact with relatively static masses of water and smaller structures, such as pipes, in contact with dynamic water masses and comprises the steps of heating the water in contact with the structure to be treated and maintaining an elevated temperature for a time sufficient to kill substantially all of the infesting organisms.
Abstract:
An in situ microwave insect eradication system (10) has a remotely deployed movable horn array subassembly (12), a proximity detector subsystem (14), a local control unit (16), and an energy absorbent backdrop (20). The horn array subassembly (12) can deploy a number of microwave horn units (32) in both horizontal or vertical arrays. The microwave horn units (32) are controlled by the local control unit (16) which determines the order, duration, and repetition of energy emitted. The proximity detector subsystem can immediately shut down the eradication system (10) upon detecting a body, such a human or pet. The backdrop (20) is deployed opposite the horn array subassembly (12) to absorb residual microwave energy.
Abstract:
The disclosure relates to a rodent exterminator wherein a box includes electrical wires at opposite sides of an entry opening thereinto with a hinged top for disconnectably providing power to the wires and permitting easy removal of an exterminated rodent with rapid availability for reuse. The box includes air vents in one side to permit the aroma of bait therein to permeate external to the box.
Abstract:
A method for repelling birds, especially woodpeckers from selected areas or surfaces which comprises applying isophorone to such areas or surfaces.
