Abstract: An oil well sealing device that is submergible for sealing under water oil wells and a method for sealing underwater oil wells are described. The device comprises a housing having at least one lower opening at a lower end of the housing and at least one upper opening at an upper end of the housing; a pump sucking oil through the lower opening into the housing and pushing the oil through the upper opening out of the housing; and a closing element movable to close or open the upper opening.

Abstract: An oil well sealing device that is submergible for sealing under water oil wells and a method for sealing underwater oil wells in such a fashion that oil production can be resumed are described. The device comprises a housing having at least one lower opening at a lower end of the housing and at least one upper opening at an upper end of the housing; a pump sucking oil through the lower opening into the housing and pushing the oil through the upper opening out of the housing; a connector allowing the lower end of the housing to be fixed to an oil well tube at an oil wellhead; and at least one valve at the lower end of the housing that is closable after the lower end of the housing has been installed to the oil well tube.

Abstract: A liquid insecticide solution comprising a 5% to 20% water solution of a disodium octaborate tetrahydrate (“DOT”) mixture comprising disodium octaborate tetrahydrate, colored pigment, and a bittering agent of either sucrose octa-acetate and denatonium benzoate, is provided. Preferably, the insecticide solution is prepared by stirring a powdered DOT mixture into water. Methods for treating wood surfaces and preparing bait stations with liquid insecticide solutions prepared with D.O.T. mixtures are also provided.

Abstract: A liquid insecticide applicator in the form of a trigger pump having a detachable, semirigid, tubular extended nozzle press fit into a recess within a nipple along the discharge end of the pump assembly is provided. When the extended nozzle is engaged to the pump assembly, the applicator is suitable for applying or injecting insecticides such as solutions of containing disodium octaborate tetrahydrate (D.O.T.) into holes or wall voids. When the extended nozzle is disengaged from the pump assembly, the applicator can deliver contents in a spray, suitable for treating larger surfaces, such as large areas of exposed wood. Preferably, the liquid insecticide solution used with the applicator is a 5% to 20% water solution of a DOT mixture comprising disodium octaborate tetrahydrate, colored pigment, and a bittering agent of either sucrose octa-acetate or denatonium benzoate.

Abstract: A method of applying a powdered insecticide directly to carpeting and other flooring includes using an applicator such as, for example, a paint roller, to evenly apply an insecticide powder to the flooring. The powdered insecticide is first deposited in a container. Then the paint roller's powder-attracting surface is first touched against the insecticide and subsequently contacted with the flooring. The paint roller is moved to distribute the insecticide evenly. If the flooring constitutes carpeting, a stiff brush may be used to brush the insecticide into the carpet fibers.

Abstract: An apparatus for simultaneously inspecting and treating a pet for the presence of unwanted insects by applying an insecticide or ointment directly to a pet's skin, hair, or fur. The apparatus comprises a blower to part the pet's hair or fur, a light to enhance visibility, a detachable pump sprayer to disperse the insecticide or ointment, and tweezers to grip and extract an insect.

Abstract: An insecticide comprising a mixture of powdered boric acid, sucrose octa-acetate or denatonium benzoate, magnesium stearate, silica gel or tricalcium phosphate, and a non-white powdered pigment.

Abstract: A method of preparing an insecticide containing boric acid which comprises milling boric acid to a particle size between about 100 to about 400 mesh; blending said boric acid particles with a member selected from the group consisting of magnesium stearate, silica gel, and tricalcium phosphate, with sucrose octa-acetate or denatonium benzoate, and with a non-white powdered pigment sufficiently soon after said boric acid is milled so that said boric acid particles remain smaller than about 100 mesh; and electrically charging said blend to induce an electrostatic charge on the discrete particles of the insecticide.

Abstract: A method of applying an insecticide, the insecticide containing a mixture of powdered boric acid, denatonium benzoate or sucrose octa-acetate, magnesium stearate, silica gel or triacalcium phosphate and a non-white powdered pigment.

Abstract: An apparatus for vaporizing wherein a vaporizer is positioned within a water closet so that the normal water level substantially fills a portion of the vaporizer. Upon discharging water from the water closet, the water level in the vaporizer falls thereby allowing air to enter the vaporizer. As the water level returns to its normal level within the water closet, the air in the vaporizer is forced into communication with a vaporizable compound and exits the vaporizer through an outlet into the atmosphere.

Abstract: An exothermic reaction is produced by the addition of water to a mixture of calcium oxide, an ammonium salt and pine oil. The mixture is included within a disposable container having means therein for receiving the water and controlling the progress thereof to the mixture. After the water is added to the container, the container is enclosed within an oven and the resulting exothermic reaction and the simultaneous liberation of ammonia from the ammonium salt causes ammonia gas, steam, and pine oil to exit from the container depositing on the oven walls ammonium hydroxide and the pine oil which exert a cleaning, dissolving, and saponifying action on grease and other foreign matter.
