  • Patent number: 10793304
    Abstract: A system for reducing oxygen in a package of produce product using a lance manifold. The lance manifold has a first end adapted to receive an input gas flow and a second end adapted for placement in a partially-enclosed cavity containing the produce product. The second end of the lance manifold includes a plurality of exit ports adapted to produce an output gas flow and a sampling port for taking an air sample from the partially-enclosed cavity. The system also includes an oxygen analyzer for detecting oxygen content of gas inside the partially-enclosed cavity using the sampling port. The system is configured to produce an output gas flow with the following properties: a substantially oxygen-free composition; a flow rate of at least 100 standard cubic feet per hour (SCFH); and a flow direction substantially 90 degrees to a cavity opening of the partially-enclosed cavity.

  • Publication number: 20140202119
    Abstract: A system for reducing metal and product-in-seal contamination in a package of produce product is provided. The system includes a tube and a flapper gate assembly. The flapper gate assembly is connected to the top of the tube, and includes a pivot and a flapper gate. The pivot is positioned outside the tube. The flapper gate is positioned inside the tube and is connected to the pivot. The flapper gate is configured to regulate product flow in the tube by rotating around the pivot when the pivot is rotated.

  • Patent number: 7044445
    Abstract: A hydraulic-mechanical vehicle elevating system for providing a built-in jack assembly which elevates a vehicle so the vehicle may be maintained. The hydraulic-mechanical vehicle elevating system includes a plurality of hydraulic jacks and/or mechanical jacks secured to a frame of a vehicle, a hydraulic pump connected to a reservoir and a control panel which controls fluid flow to the hydraulic jacks, and a crank handle.

  • Patent number: 5406448
    Abstract: A hanger for a power factor capacitor and method of attachment by brazing reduces metallurgical changes that can lead to cracks in the tank wall from welding. The hanger has a base plate with a circular opening and a raised shoulder that provides a single ring of contact between the tank wall and hanger. A ring of brazing alloy is placed within the opening on the tank wall. Through induction of electric current, the brazing alloy melts and flows resulting in a complete braze between the hanger and the tank wall which is accomplished at a much lower temperature than other welding techniques.
