Patent number: 7364097Abstract: A water-saving type shower head operable to reduce flow volume while maintaining a high discharge pressure. A diameter-reduced water passage 19 of a flow control member 20 disposed in a head portion 22 of a shower head body 12 has a first and a second water passage portions 40 and 41 provided on an entry side and an exit side thereof, respectively. The first water passage portion 40 has a small diameter, and the second water passage portion 41 has an inside diameter which is 1.5 to 3 times that of the first water passage portion 40. On an upstream side of the first water passage portion 40, a tapered diameter-reduced portion 43 reduced in diameter in a flow direction is formed, and on a downstream side of the second water passage portion 41, a diameter-increased portion 45 increased in diameter in the flow direction is formed.Type: GrantFiled: November 18, 2005Date of Patent: April 29, 2008Inventor: Yoji Okuma

Patent number: 7360724Abstract: A nozzle is provided for use in a dynamic electrostatic air filter, in which the nozzle includes an internal electrode that charges a semiconductive liquid, and includes an external electrode that assists in breaking the liquid into droplets in a predetermined direction. Banks of multiple nozzles are also disclosed, which are separated by a charged “separation electrode” to prevent interference with spray patterns between adjacent banks. An electrostatic fountain is also disclosed which discharges a fragrance, or an inhalable medicine.Type: GrantFiled: October 20, 2004Date of Patent: April 22, 2008Assignee: The Procter & Gamble CompanyInventors: Alan David Willey, Vladimir Gartstein, Chinto Benjamin Gaw, John Rolland Shaw, William Richard Mueller, Krista Beth Comstock

Publication number: 20080073449Abstract: Rotating Relaxer Shower Head has a housing with multiple heads that rotate and a standard connection for use with piping in a bathroom. A user simply turns the shower on in the ordinary manner and positions his body underneath the housing with the multiple showerheads. Water enters the housing through the standard connection and spins the multiple showerheads, causing a rotating stream of water to be emitted through the plurality of holes in the heads. The water then contacts the user in a rhythmic, rotating manner that helps relax and cleanse a user.Type: ApplicationFiled: September 25, 2006Publication date: March 27, 2008Inventors: John L. Haynes, Mercedes Haynes

Patent number: 7316122Abstract: A tray assembly for use in feeding liquid composition to a freezing chamber is disclosed. The tray has a plurality of projections that are designed to provide regulated discharge of the liquid composition from the tray and to feed the liquid composition into the freezing chamber in uniformly sized drops. The projections area each downwardly disposed in relation to the tray. The tray has a bottom wall with a plurality of orifices, where each orifice is associated with a corresponding projection. These projections are uniform in size and can be formed using computerized welding techniques. An alternate embodiment in which the tray is pressurized is also disclosed.Type: GrantFiled: January 6, 2004Date of Patent: January 8, 2008Assignee: Dippin' Dots, Inc.Inventors: Curt D. Jones, Stan Jones

Patent number: 7225999Abstract: Spray array apparatus which includes a plurality of water and air carrying spoke members extending radially from a central fluid distribution assembly. The spoke members are connected to a plurality of water and air carrying strut members. The spoke members are divided into segments and the segments and strut members are detachably joined together by means of manifold joints which have water and air passageways allowing fluid communication between spoke segments and strut members. The apparatus is towed at the end of a boom of a tanker aircraft and is connected to the boom by means of a gimbal allowing two degrees of freedom to reduce bending moments and connection stresses. Selected fluid parameters are transmitted to the tanker aircraft to adjust fluid flow, if necessary.Type: GrantFiled: September 23, 2004Date of Patent: June 5, 2007Assignee: The United States of America as represented by the Secretary of the NavyInventors: Curt M. Foianini, Thomas H. Hane, Joseph E. Wolfe
