Patent number: 7258253Abstract: Devices, systems, and methods for the precise dispensation of small volumes of liquids are presented. A fluid microdispenser comprises a liquid-filled tube, an actuator coupled to the tube, and a tip at one end of the tube. When the actuator applies an actuation pressure, a precise volume of liquid is ejected from the orifice of the tip. The orifice is manufactured to control the volume of liquid ejected by each actuation and, therefore, may have a diameter smaller than that of the liquid-filled tube. The invention comprises systems, methods, and devices so that the inner diameter of the liquid-filled tube is decreased (tapered) to that of the orifice so as to maximize transmission to the orifice of the pressure generated by the actuation stimulus. This enables the volume of liquid ejected by each stimulus to be reproducibly controlled by the amplitude of the actuation stimulus.Type: GrantFiled: April 30, 2004Date of Patent: August 21, 2007Assignee: Aurora Discovery, Inc.Inventors: David Nicol, Binh Nguyen, Peter J. Coassin

Patent number: 7222645Abstract: An insulated duct-wrap insulating product for an air duct that incorporates a wicking media to transport condensed water on the duct surface to be evaporated into the atmosphere. A wicking fabric, or fibrous media, incorporated as part of the insulating duct wrap is in contact with the metal air duct surface. A portion of the wicking fabric extends into the interior of the air duct, typically through joints in the duct system. When water vapor condenses on the air duct surface it is transported by the wicking fabric and evaporated from the wick surface within the air stream being transported by the ducting system.Type: GrantFiled: October 31, 2003Date of Patent: May 29, 2007Assignee: Owens Corning Fiberglas Technology, Inc.Inventors: Roy Shaffer, Manoj K.

Patent number: 7207354Abstract: The present invention provides an improved tubular structure which uses the properties of different materials, such as stiffness, strength, and density are exploited in a manner which combines the most attractive characteristics of existing metal and composite tubes into a metal/composite tube which contains performance characteristics (stiffness, strength or weight) not possible with pure metal or composite materials. For example, an improved tube is suitably created with a conventional metallic tube structure (e.g., steel, aluminum, titanium or the like). The original tube is modified with a secondary operation such as machining, punching, laser cutting or the like to remove various portions of the original tube wall, resulting in a tube with some pattern of “holes” or “cutaway” sections, thus resulting in a lighter tube. The tube is then suitably “fused” with composite material.Type: GrantFiled: March 4, 2005Date of Patent: April 24, 2007Assignee: Vyatek Sports, Inc.Inventor: Howard A Lindsay

Patent number: 7163028Abstract: A multipurpose plumbing tool has a body at one end, a head at an opposite end and an intermediate neck portion connecting the body and head. The marginal end portion of the body is cut back to form a reduced section, a shoulder being formed at the junction of the reduced section and a non-reduced section of the body. The reduced section is internally and externally threaded. An inwardly tapered seat for an O-ring is formed in the shoulder. An O-ring positioned in the tapered seat is compressed and contained within the tapered seat to provide a water tight seal when the externally threaded end is threaded into a female fitting. The free end of the head is formed with an internally threaded socket. A washer seated at the bottom of the socket provides a water tight seal when the socket is screwed onto a male plumbing fitting.Type: GrantFiled: May 23, 2005Date of Patent: January 16, 2007Inventors: Manuel Diaz Atkinson, Mark Abraham
