Patent number: 4453930Abstract: A method and instrument for placing an implant in the teat duct and udder of an animal, as a milk cow. The instrument has an elongated tubular member having a passage accommodating the implant. The tubular member is adapted to be inserted into the milk duct through the discharge end thereof. A head having finger gripping ears is attached to the tubular member. The implant is moved from the passage with a piston connected to a rod extended through the head. A hand engaging member secured to the rod is used in cooperation with the ears to apply force to the rod to move the piston in the passage to move the implant into the teat duct and udder. The implant has a core of an elongated flexible plastic string. A plurality of bands are clamped about the core. Alternate bands are coated with a first metal, as silver. The remaining bands are coated with a second metal, as gold. All of the bands may be coated with the same metal, such as silver.Type: GrantFiled: December 11, 1980Date of Patent: June 12, 1984Assignee: Child Laboratories Inc.Inventor: Francis W. Child

Patent number: 4385633Abstract: A dilator for a teat of a dairy cow operates to facilitate the flow of fluid from the teat. The dilator has a body having a passage adapted to be positioned in communication with a duct of the teat. An elongated tubular member extends from the body into the duct. The tubular member has a passage allowing the flow of fluid through the dilator. A one-way valve mounted on the body allows the flow of fluid out of the dilator and restricts the entrance of external foreign substances back into the passage and duct of the teat. The valve has flexible side walls terminating in normally closed lips. A slit mouth is located between the lips. The slit mouth can be opened to facilitate the dispensing of medicinal compounds into the teat and udder of the mammal. An inserter having a rod extended through the one-way valve and tubular member is used to place the dilator in the teat duct and duct outlet, with the one-way valve located at the terminal end of the teat.Type: GrantFiled: June 25, 1981Date of Patent: May 31, 1983Assignee: Child Laboratories Inc.Inventor: Francis W.

Patent number: 4344404Abstract: An apparatus for supplying aerosol fuel particles uniformly mixed with air to utilizer, as an internal combustion engine or burner. The apparatus has several fuel mixing and atomizing nozzles operable to mix one or more liquid hydrocarbon fuels and discharge the fuels through orifices in small fuel particles of uniform size. The fuel particles are mixed with air and flow through a pair of venturi throats with converging inlet walls and diverging outlet walls. The velocity of the air and fuel particles flowing through the venturi throats is at or above the speed of sound. The fuel particles are finely divided into particles between 0.5 and 1.5 micron in diameter as they move through the turbulent inlet and outlet interfaces of the air flowing through the nozzle throats at sonic and supersonic velocities and are evenly distributed into the air. The length or major dimension of one of the venturi throats is regulated with a baffle in accordance with the speed requirements of the engine.Type: GrantFiled: December 21, 1979Date of Patent: August 17, 1982Inventors: Francis W. Child, Richard O. Bartz

Patent number: 4301796Abstract: A dilator for use in a bovine animal's teat for controlling the flow of fluid from the teat is packaged in an envelope containing a disinfectant solution. A collapsible dispensing bag containing material, as antibiotics, is located within the envelope. An elongated dispensing tube connected to the bag carries the material from the bag to the teat duct accommodating the dilator. The envelope has releasable seals which permit the envelope to be opened to expose the dilator. The envelope is used as a cover to maintain the dilator in a sterile condition as it is inserted into the duct of the teat. The material in the bag is moved from the bag by applying a squeezing force to the envelope and bag. After all of the material is squeezed from the bag, the dispenser and envelope are removed from the teat and dilator.Type: GrantFiled: July 26, 1979Date of Patent: November 24, 1981Assignee: Child Laboratories Inc.Inventor: Francis W.
