  • Patent number: 6401655
    Abstract: A milking claw having a barrel-type body and a pair of windows for enclosing a chamber therebetween includes a seal which prevents engagement between the windows and the body. The seal is preferably a rubber seal molded to the perimeter of the window. The seal includes a bead for receipt within an annular groove of the body, and a flange extending longitudinally therefrom. The window preferably includes a concave outer surface which is recessed relative to the longitudinally outwardly facing margin of the body. The outer surface of the window also preferably includes a relieved area centered thereon, permitting enhanced gripping of the claw. The relieved area may be provided by either a raised area molded into the window or a depression in the window.

  • Patent number: 6298807
    Abstract: A barrel claw of increased volumetric capacity without sacrificing ergonomics has a normally horizontally disposed, elongated hollow body having a generally cylindrical central portion and a pair of tapered, conical end portions on opposite sides of the central portion. Viewing windows at opposite ends of the body permit observation of the internal chamber from outside the body. Inlet openings from the teat cups are provided in the top wall section of the body in the tapered end portions thereof so that the inlets are properly angled toward the teats of the cow's udder during use of the claw. An integrated discharge spout and pulsation manifold unit is removably attached to the top of the body in any one of a number of rotative positions so as to most advantageously position the radially projecting spout of the unit relative to the observation windows and other equipment associated with the milking system.

  • Patent number: 4671435
    Abstract: A programmable, wide area insecticide (or other airborne chemical agent) dispensing system and method is disclosed in which a supply of a fluid insecticide is maintained and delivered under pressure to one or more spray heads which may be located remotely from the supply, as for example in various locations within a warehouse, dairy barn, or the like. A programmable controller effects the dispensing of the insecticide from the selected spray heads at predetermined times and in predetermined amounts so as to effectively control insects at various areas of the building at various times of the day so as to avoid indiscriminate spraying of the insecticide when it is not needed, or when it may interfere with activities within the building.
