Patent number: 8671884Abstract: A method of attaching and/or removing a teat cup from an animal with a liner inflatable and deflatable by a pulsator which alternately introduces air and vacuum to a pulsation chamber surrounding the liner. The method comprising the steps of: setting the pulsator to constantly introduce vacuum to the pulsation chamber to open and maintain the liner in an open position for an attachment time period; attaching the teat cup to the animal during the attachment time period; setting the pulsator to alternate between introducing air and vacuum to the pulsation chamber during a milking time period to milk the animal; and removing the teat cup from the animal.Type: GrantFiled: April 27, 2011Date of Patent: March 18, 2014Inventors: Lanny Gehm, William Gehm

Patent number: 8408159Abstract: A portable apparatus for milking animals, that can be carried by a person to any location, preferably in a bag such as a hand bag, side bag or backpack. The portable apparatus includes a carrying device, a power unit including a vacuum pipeline, a milk pipeline having a milk reservoir, and a milking claw unit, having one or more teat-cups. The vacuum pipeline provides suction force to the teat-cups that operatively draw milk from the animal udder. The milk pipeline operatively connects the teat-cups to the milk reservoir. Vacuum force further creates partial vacuum in the milk reservoir, and along with gravity the drawn milk flows to the milk reservoir. The portable apparatus can be used to milk animals located at sites accessible only by foot. The portable apparatus can be used to milk colostrums after parturition, and to milk animals having infected udder/teat.Type: GrantFiled: April 26, 2009Date of Patent: April 2, 2013Assignees: TRM Tiram Import Agencies Ltd.Inventors: Moshe Uziel, Zvi Verfel

Patent number: 8397671Abstract: The invention relates to a milking device for milking animals, the required vacuum being, for example, generated by generating compressed air using a compressor and passing said compressed air through the system, the compressed air creating a vacuum at all required locations by means of the Venturi system. Because this vacuum differs at the various locations, the reduced pressure can be regulated precisely and adapted as required.Type: GrantFiled: February 8, 2008Date of Patent: March 19, 2013Assignee: Hanskamp Agrotech B.V.Inventor: Hendrik Jan Hanskamp

Patent number: 8356577Abstract: A combination of a teat cup and a flexible milk tube is shown. The flexible milk tube has a main duct and a plurality of secondary ducts for discharging milk from the teat cup and for applying vacuum in the teat cup. The main duct is confined by a duct wall extending around the main duct. The secondary ducts are included in the duct wall of the main duct. By including the plurality of secondary ducts in the duct wall of the main duct the flexible milk tube as a whole has a smaller cross-section than that of the known milk tube. The plurality of secondary ducts no longer need separate duct walls forming separate tubes either connected or not with the flexible milk tube comprising the main duct. This results in space saving.Type: GrantFiled: September 28, 2010Date of Patent: January 22, 2013Assignee: Maasland N.V.Inventor: Karel Van Den Berg

Patent number: 7975647Abstract: A milking apparatus that is used to extract milk from dairy animals includes a vacuum source, a milking liner cooperating with a shell to define a pulsation chamber; and a pulsator in fluid communication with the pulsation chamber and the vacuum source. The pulsator is configured to produce at least a four-phase milking cycle in the milking liner with the cycle including at least an A phase and a C phase. The A phase is wherein the liner is changed from a closed configuration to an open configuration during which the pulsator provides fluid communication between the pulsation chamber and the vacuum source. The C phase is wherein the liner is changed from an open configuration to a closed configuration during which the pulsator allows atmospheric air to flow into the pulsation chamber. A restrictor is disposed in the path of the fluid communication between the pulsator and the pulsation chamber with the restrictor slowing the C phase compared to the A phase.Type: GrantFiled: September 21, 2008Date of Patent: July 12, 2011Assignee: Lauren AgriSystems, Ltd.Inventors: Frank Saho, III, Daniel E.

Publication number: 20100121263Abstract: The invention provides a system and a method of eliciting milk from all mammals that possess teats, including but not limited to dairy animals and humans. A system may be comprised of an elastic system and a vacuum supply. A method may include a milk elicitation system comprised of an elastic system and a vacuum supply. Through the application of vacuum, the elastic system forms, differentiates, seals and adapts to a teat, from the area it ends until up to where the udder ends and it begins, without coming in contact with the teat-end sphincter/lactiferous duct(s). The elastic system interacts proportionately according to the tendencies expressed by teat physiology and dynamics according to the milk pressure change, blood flow, and the effects of applied vacuum, throughout the milk elicitation process, resulting in continuous and complete milk elicitation and supporting the physiological teat return, after the process.Type: ApplicationFiled: January 17, 2008Publication date: May 13, 2010Inventors: Elona Farka, Andrea Pappa, Georgios Pappageorgiou
