  • Patent number: 7517414
    Abstract: The application of a gel-like material is disclosed for cleaning a surface having foreign matter thereon, such gel-like material produced by magnetically treating and mixing two solutions, the first solution being comprised of water and sodium bicarbonate and the second solution comprised of water and sodium silicate. The first solution is passed through a positively charged magnetic field, and the second solution is passed through a negatively charged magnetic field. The two solutions are then mixed together to form a gel.

  • Patent number: 7473026
    Abstract: In a method of cleaning a rotary mixing device having a mixer portion and a driving shaft, a shield is located over at least the mixer portion. The mixing device is rotated, expelling material clinging to or trapped by the mixing portion, such as paint, from the mixer portion of the mixing device. This material is blocked or caught by the shield. In one embodiment, the shield is cylindrical in shape and has a base with an opening through which the shaft of the mixing device may extend, and an open second end leading to an interior area for containing the mixer portion of the mixing device.

  • Publication number: 20080289662
    Abstract: Compositions and methods for degreasing and lubricating objects, such as mechanical devices and the like. A composition comprised of a mixture of ethanol and food-grade mineral oil is applied directly to the substrate or objects sought to be degreased or lubricated. For degreasing applications, an amount of the composition is applied in an amount sufficient to penetrate and loosen grease-covered substrates, and is particularly well suited for hand wiping applications. Such methods can also be utilized to remove paint and ink. The compositions are substantially effective yet relatively non-toxic and biodegradable.
