  • Patent number: 5720825
    Abstract: This invention relates to a method for cleaning bituminous asphalt- and tar-coated equipment, using combinations of alkyl esters with terpene cosolvents and/or surfactants. The specific invention is the use of ester solvents in combination with terpene solvents, optionally with emulsifiers and other additives. The combination of the two is found surprisingly to exhibit the excellent solvency of terpene solvents, but with the slower evaporating rate and higher flashpoint properties of ester solvents.

  • Patent number: 4113273
    Abstract: A multiple implement folding hitch designed to permit a plurality of implements to be pulled in a side-by-side relationship during field operations and adapted to permit the effective width of the implements to be reduced for transport purposes. The hitch comprises a transversely extending frame comprising a plurality of frame members pivotally secured together in an end-to-end relationship. First and second spaced apart trailing implements are operatively secured to opposite ends of the frame. A first tubular member extends forwardly from the transversely extending frame and has its forward end adapted to be connected to the prime mover. A second tubular member is telescopically received by the rearward end of the first tubular member and has a third trailing implement connected thereto which is positioned between the first and second implements. First and second elongated members are pivotally connected at their forward ends to the first tubular member and extend rearwardly and outwardly therefrom.
