  • Publication number: 20060235071
    Abstract: A method for repelling arthropods involving treating a subject or an object with an arthropod repelling composition containing an arthropod repelling effective amount of at least one clerodane of the formula in which R1 is H, halogen, formyl, a straight chain or branched C1-4 saturated alkyl, a straight chain or branched C2-4 unsaturated alkyl, or an aryl containing 6-10 carbon atoms in the ring skeleton thereof, wherein R1 is unsubstituted or substituted with one or more substituents, which are the same or different, selected from the group consisting of oxo (?O), OR2, CO2R2, and OC(O)R2, wherein R2 is H, a straight chain or branched C1-30 saturated alkyl, a straight chain or branched C2-30 unsaturated alkyl, or an aryl comprising 6-10 carbon atoms in the ring skeleton thereof; wherein R2 is unsubstituted or substituted with one or more substituents selected from the group consisting of halogen, amino, hydroxyl, oxo (?O), thio, cyano and nitro; optionally a carrier, optionally an arthropod repellant, an

  • Patent number: 6536686
    Abstract: The selector wheel is mounted to rotate about the axis of the nozzle cap, and a spray window and foaming sleeve are formed in the wheel offset from the axis. The window or sleeve is registrable with the offset spray orifice by rotating the wheel. Either window or sleeve can be brought into registry so that the discharge is spray or foam.

  • Patent number: 6494171
    Abstract: A two or four stroke internal combustion engine has a ported plate with a series of intake and exhaust ports connected respectively to an air intake and an exhaust system. A shaft is rotatable relative to the ported plate. the shaft carries a crank shaft with a crank axis oblique to the shaft axis. An array of one or more combustion chambers rotates about the shaft axis. Each combustion chamber includes at least one port which is brought into and out of operative communication with the series of intake and exhaust ports as the combustion chamber moves over the face of the ported plate. A piston reciprocates in each combustion chamber under the control of a wobbling member journalled onto the crank shaft. For each combustion chamber port an annular seal is located within an annular groove about the port and is biased toward the ported plate by combustion fluid pressure.

  • Publication number: 20020170511
    Abstract: An engine/pump having a crank shaft with a shaft axis and a crank axis oblique to the shaft axis which intersect with each other. Piston/cylinder assemblies rotate about the shaft axis and have a reciprocal axis between its top dead center and bottom dead center. The reciprocal axis midway between TDC and BDC being normal to a line projected from the intersection of the shaft axis and the crank axis. A cylinder head holds the cylinders in an array, The head includes at least one port per cylinder, and a port relative to which the cylinder head moves sealably to allow timed to the reciprocal movement of each piston in its cylinder and the rotational position, the opening and closing of each cylinder. Each cylinder is indexed at a predetermined rate to the relative rotation of the crankshaft through gearing.

  • Patent number: 6446882
    Abstract: The invention is a trigger sprayer comprising a tubular nozzle bushing and a nozzle cap rotatable on the bushing. The nozzle cap has an end wall with a first swirl chamber formed on the rear face thereof offset from the axis. Passages to a second chamber are diametrically opposite the first chamber. Both chambers have orifices directed out the front of the cap. The first orifices is surrounded by a foaming sleeve. The second orifice is positioned forward of the first orifice so that the spray cone emanating from the second orifice does not hit the foaming sleeve. The cap can be rotated to connect liquid from the delivery tube to the swirl chamber for one or the other orifices.
