Abstract: A food sterilization tube includes a layer including a fluoropolymer, wherein the fluoropolymer includes a copolymer of tetrafluoroethylene and perfluoropropyl vinyl ether (PFA), a fluorinated ethylene propylene copolymer (FEP), polytetrafluoroethylene (PTFE), or combination thereof, wherein the fluoropolymer has a dielectric constant of less than 3 as measured by ASTM D150.

Abstract: A safety system for transfer of pressurized fluid between a cargo tank vehicle and a storage container. A pump or compressor on the cargo vehicle is in fluid communication with the cargo tank, the pump being powered by the vehicle. A pump valve on the vehicle between the tank and the vehicle pump will interrupt fluid passing into the pump. A delivery hose having a first end in fluid communication with the pump and a second end in fluid communication with the storage container transfers the pressurized fluid between the pump and storage container. A first pressure sensor senses pressurized fluid in the delivery hose near the hose second end. A first switch activated by the first pressure sensor closes the pump valve and interrupts the fluid flow. A second pressure sensor senses pressure near the hose first end. A second switch activated by pressure from the second pressure sensor closes the pump valve and interrupts fluid flow.

Abstract: A shortened electrical grounding system for use with a vertical antenna, particularly AM limited range information stations. The grounding system has a plurality of fractional wavelength electrically conductive members joined together and connected to the electrical ground of the transmitter associated with the antenna. The fractional wavelength electrically conductive members can be made of wire or metal panels both of which can be fanned out about the base of the vertical antenna in a substantially circular pattern. The electrical grounding system can be buried in the ground or can be used above ground as a counterpoise. The electrical conductors making up the ground system can also be incorporated into a mat made of plastic or other suitable material which can be positioned at the base of the vertical antenna.

Abstract: Improved apparatus useful in conjunction with a forage wagon to allow forage material to be removed from the wagon by dispensing it laterally toward the side of the wagon or, alternatively, to dispense the material directly out the front of the wagon to the area beneath the wagon such as in the filling of a trench silo. The improved apparatus includes a lateral feed conveyer affixed to the front end of the forage box by a removable attachment apparatus. Bottom and top collecting pans located beneath the lateral feed conveyer form a removable delivery surface and are constructed of discrete sections which are mounted on rail members for selective removal and replacement.
