Abstract: An automatic bag opening apparatus for sequentially opening at least one bag, preferably a mesh bag, comprising a frame, a wicket for holding the bag wherein the mesh bag adjacent the forward end of the wicket is the outermost mesh bag, a first clamp disposed adjacent the forward end of the wicket, an air dam slidably mounted to the frame, an opener clamp slidably mounted to the frame, and a nozzle or other means for directing a pressurized fluid through at least a portion of the first, or outer, side of the outermost mesh bag adjacent its open end and onto the air dam. In operation, the first clamp is positioned in contact with the outermost mesh bag, the air dam is located adjacent the open end of the first side of the outermost mesh bag the pressurized fluid is directed through a portion of the open end of the first side of the outermost mesh bag adjacent its open end and onto the air dam, which causes the portion of the mesh bag through which the pressurized fluid is directed to move towards the air dam.

Abstract: A one-handed soldering apparatus comprises a solder dispensing unit and a solder melting unit mounted in a cooperating manner to provide for one-handed dispensing and melting of solder from a single combination device. A unique solder discharging device provides for the controllable flow of a solder paste which flow is begun and halted upon command with a minimum of unwanted oozing of excess paste.
