  • Patent number: 5723424
    Abstract: The invention pertains to a cleaning mixture for use in cleaning concrete pads. The mixture consists of two components and each of the two components has two ingredients. The first ingredient of the first component consists of an OIL-DRI -type all purpose absorbent clay material while the second ingredient is a cat litter or an addapolgite-type clay. Both of the ingredients of the first component are of a granular material. The second component also has two ingredients, the first is a Kaolin-type clay and the second ingredient is a finely ground clay dust. The first component, when applied to the surface of a contaminated concrete, will loosen and break up the hardened oil or grease deposit while the ingredients of the second component, when applied to the concrete surface after the the residue of the first component has been removed will absorb the oil from the pores and crevices of the concrete and apply a whitening effect to the concrete and also will seal the pores and the crevices of the concrete.

  • Patent number: 5714484
    Abstract: Cysteine protease inhibitors which deactivate the protease by covalently bonding to the cysteine protease and releasing the enolate of a 1,3-dicarbonyl (or its enolic form). The cysteine protease inhibitors of the present invention accordingly comprise a first portion which targets a desired cysteine protease and positions the inhibitor near the thiolate anion portion of the active site of the protease, and a second portion which covalently bonds to the cysteine protease and irreversibly deactivates that protease by providing a carbonyl or carbonyl-equivalent which is attacked by the thiolate anion of the active site of the cysteine protease to sequentially cleave a .beta.-dicarbonyl enol ether leaving group.
