  • Rake attachment
    Patent number: 4514970
    Abstract: A rake attachment for combining two conventional rakes to be used as a pick-up rake. The attachment provides two handle clamps, which may be substantially identical, each clamp to be attached to the free end of a rake handle. One rake handle is attached to its clamp to prevent rotational and longitudinal movement of the handle with respect to the clamp. The second handle is fastened to its clamp so as to allow rotation of the rake handle. The two clamps are then detachably and hingeably connected. The second rake may be rotated to bring its tines in opposition with the tines of the first rake, for use as a pick-up rake. Alternately, the second rake may be rotated so as to nest its tines with those of the first rake, allowing use of the apparatus as a conventional rake. Further, the clamps may be detached from one another, allowing each rake to be used for conventional raking.

  • Aqueous coating compositions and process for their preparation from epoxy acidic acrylic polymer and polyfunctional amine
    Patent number: 4501831
    Abstract: Aqueous compositions suitable for use as sanitary container coatings are prepared by reacting epoxy resin and a carboxyl containing acrylic resin in the presence of a polyfunctional tertiary amine. The compositions made with polyfunctional amine have lower viscosities than those made with monofunctional amine, an advantage in preparing high solid coatings for roll application, for example.
