  • Patent number: 6782927
    Abstract: A can filler valve wiper mechanism for use with a can filler machine is disclosed. The can filler machine includes mechanism for moving a can along a predetermined can travel path, and a movable filler valve which moves along a predetermined filler valve travel path above at least a portion of the can travel path. A can wiper mechanism comprises a rotating wiper, which can be a common paint roller. The rotating wiper is disposed at a location between a moving can and a moving can filler valve located above the can so that the wiper engages and collects material located between the valve and can. Preferably, the wiper engages the bottom of the filler valve itself as the valve passes the wiper.

  • Patent number: 6717285
    Abstract: A wind powered generating device comprises a tube cluster, a collector assembly, and a turbine assembly. The collector assemblies utilize sails that can be rotated to direct wind down through an inlet tube to a central outlet tube. The central outlet tube is narrowed at a portion, and a turbine is mounted at this narrowed portion to take advantage of the Venturi effect that accelerates the air as it passes the turbine. This permits reliable and efficient operation in areas that were not formerly considered windy enough to be economically feasible for the deployment of wind powered generating devices. Alternative embodiments of the invention include mechanisms for dealing with violent weather conditions, a first of which allows excess wind to bleed off beneath and between the sails, and a second which collapses and covers the sail with a protective sheath/sock.
