20090293214DRAIN CLOG REMOVER AND SHAFT USABLE THEREWITH - An apparatus for removing drain clog material from a drain pipe assembly. The assembly has: (a) a container, and (b) a shaft. The container defines a reservoir adapted to receive a drain cleaning composition. The container also has an outlet. The shaft is attached to the outlet of the container and is in fluid communication with the container. The shaft also has an X-direction, a Y-direction perpendicular thereto, and a Z-direction perpendicular to both the X- and Y-directions, in addition to a plurality of barbs extending outwardly. The barbs have a force to remove of less than 20 lbs.; and a peak bend force of less than 4 lbs.12-03-2009
20110088153NON-CONTACT SPRAY TOILET BOWL CLEANING DEVICE - A device for spraying an inner surface of a toilet bowl with a cleaning fluid is disclosed. The device includes a container for the fluid, a fluid spray bar through which the fluid can be sprayed on the wall of the enclosure, a pumping apparatus for delivering fluid from the container to the fluid spray bar, and a controller. The fluid spray bar includes spray nozzles with different configurations and nozzle bodies to effectively spray the inner surface of the enclosure.04-21-2011
20110088154RELATIVELY COMPACT NON-CONTACT SPRAY TOILET BOWL CLEANING DEVICE - A device for providing cleansing composition to the inner surface of a wall of an enclosure with a fluid, the device having: (a) a first fluid spray bar having an interior space for receiving fluid from a source of the fluid and for spraying the inner surface of the wall of the enclosure. The first fluid spray bar has at least a first spray hole through which cleansing composition may be sprayed, the first spray hole being in fluid communication with the interior space of the spray bar. Additionally, the first spray hole provides a first tangential spray.04-21-2011

20090032049Ventilated Device for Delivery of Agents to and through the Human Scalp - A method and device for administering minoxidil and other topical solutions to the scalp. The method entails administering a minoxidil preparation through a manifold that fits over the scalp of a patient, and placing a moisture barrier over the scalp for a period of time effective to enhance absorption of the minoxidil preparation by the scalp.02-05-2009
20090036800Hair Densitometer - A hair densitometer measures the number of hair shafts in a fixed area and measures the diameters of the counted hair shafts. This is done for two different areas of the head and the comparison results in a quantified measure of the thinning of a persons hair on their head.02-05-2009
20090036845Device For Delivery Of Agents To And Through The Human Scalp - A method and device for administering minoxidil and other topical solutions to the scalp. The method entails administering a minoxidil preparation through a manifold that fits over the scalp of a patient.02-05-2009
20090037280Method of Diagnosing Hair Thinning and Business Method for Promoting Sales of Hair Treatment Products - A method of business uses a hair and or scalp scanner such as a hair densitometer to raise awareness of the prevalence of hair thinning. Incentives provided to hair care providers for using the hair scanner increases the likelihood that clients of the hair care provider will be exposed the hair scanner. Sales of hair regrowth products may also be discounted for clients of hair care providers.02-05-2009
20100106077Methods, Compositions and Apparatus for Treating a Scalp - A phototherapy light cap is a flexible, generally hemispherical cap having a light source to supply suitable dosage requirements of current and future light therapies. The phototherapy light cap may also include a rechargeable battery source, a light source or an array of light sources, a light diffuser and an interface to a recharging source that may be a docking station. A phototherapy light cap may alternatively be an insert for any commercial head dressing, preferably adapted for convenient recharging. Combining the use of a phototherapy light cap with gelatinized therapeutic agents provides a suitable treatment technique for a scalp utilizing phototherapy, heat and any suitable combination of active ingredients such as minoxidil.04-29-2010

20100096879Serviceable fabric assembly for convertible of a motor vehicle - The present invention is a serviceable fabric assembly for a convertible roof of a motor vehicle having a retainer connected to a fabric cover and slidably engaged within a channel formed in a first bow member. The first bow member has an upper panel and a lower panel configured to form the channel substantially along the longitudinal length of the first bow member. The channel is configured to laterally receive a compressible portion of the retainer which prevents the retainer from exiting the channel in a direction transverse to the longitudinal axis of the first bow member. A gap is formed near at least one end of the channel on the outboard side of the channel and is sized such that an operator can slide the retainer out of the channel through the gap for servicing and replacing the fabric cover without having to disassemble the first bow member.04-22-2010
