    Abstract: A utility cushion that includes a scenting agent disposed upon the cushion and a cover material. When the cover material encases the cushion, the cover material is made at least partially permeable to the scenting agent such that the application of pressure to the cushion will cause the scenting agent to permeate the covering material. Accordingly, a method for increasing the concentration of a scenting agent in the area proximal to the cushion is practiced.

  • Publication number: 20070246994
    Abstract: A method of producing hydrocarbon fluids from a subsurface organic-rich rock formation, for example an oil shale formation, in which the oil shale formation contains water-soluble minerals, for example nahcolite, is provided. In one embodiment, the method includes the step of heating the organic-rich rock formation in situ. Optionally, this heating step may be performed prior to any substantial removal of water-soluble minerals from the organic-rich rock formation. In accordance with the method, the heating of the organic-rich rock formation both pyrolyzes at least a portion of the formation hydrocarbons, for example kerogen, to create hydrocarbon fluids, and converts at least a portion of the water-soluble minerals, for example, converts nahcolite to soda ash. Thereafter, the hydrocarbon fluids are produced from the formation.

  • Publication number: 20070246996
    Abstract: The wheel of the present invention features a central hub enclosing recessed appendages. The appendages are preferable fin shaped or blade shaped. As the rotation of the wheel increases in speed, the appendages will extend out of the central hub due to centrifugal force. When fully extended, the appendages will extend to the outer-diameter of the tire. As the rotation of the wheel decreases in speed, the appendages will retract back into the hub. Tension from a spring or similar mechanism may be used to maintain the appendages in the recessed position when the wheel in not in motion. The present invention may also be in the form of wheel cover, such as a hubcap, wherein the recessed appendages are enclosed within the central portion of the wheel cover. The wheel cover is intended to be fastened to the wheel of an automobile in the same manner as hubcaps of the prior art. As the rotation of the wheel increases in speed, the appendages will extend out of the wheel cover due to centrifugal force.

  • Publication number: 20070247031
    Abstract: A piezoelectric actuator that can be operated in the d31 mode and which controls the potential energy of a spring is disclosed. The d31 mode of operation provides large actuator displacement and the potential energy of the spring significantly increases the force and work produced by the actuator. In a first embodiment, a single piezoelectric element, operating in the d31 mode, controls the potential energy of the spring. In another embodiment, two piezoelectric elements, both operating in the d31 mode, control the potential energy of the spring.

  • Publication number: 20070247032
    Abstract: An object of the present invention is to provide a crystal device that has stable vibration characteristics and that offers high reliability and high accuracy. The crystal device includes a first major face, which contains a portion of a base and a portion of a vibrating prong within a single plane, formed on the crystal plate, and a second major face, which contains another portion of the base and another portion of the vibrating prong within a single plane, formed on a crystal plate, wherein the first major face and the second major face have different outer shapes. The shapes of the first and second major faces can be produced by first forming mask layer patterns on a crystal substrate by exposure through different mask patterns and then etching the crystal substrate using the thus formed mask layer patterns.
