  • Patent number: 5827922
    Abstract: Curable composition comprising a stable, water dispersible, curable polymer containing a sterically hindered alkoxylated silane group at 0.1 to 75 weight percent of the total composition; a water dispersible or water soluble, hydrolytically stable organotin catalyst, at 0.1 to 10 weight percent of the total composition; and water at 99.8 to 24.9 weight percent of the total composition are taught herein. These compositions are useful as adhesives, sealants and paints. The compositions have improved properties including solvent resistance, adhesion, hardness, abrasion resistance and mar resistance.Particular catalysts for use herein include mercaptoalcohol, mercaptide and sulfide forms of diorganotins having either a Sn--S or Sn.dbd.S bond, and include dibutyltin dimercaptide and dibutyltin bis(1-thioglycerol).

  • Patent number: 5547113
    Abstract: An automatic feed supply machine comprising a housing containing a feed container. The feed container has a flexible bottom wall and a pushing plate for moving feed to an outlet. The outlet is closed by a disk. A motor vibrates the flexible bottom and moves the pushing plate. A common actuating lever moves the disk to an open position and operates the motor to dispense feed through the opening and into and through a nozzle.

  • Patent number: 5393330
    Abstract: The present invention teaches masonry water repellents comprising aqueous emulsions of alkylalkoxysilanes with either a quaternary ammonium surfactant or a mixture of a quaternary ammonium surfactant with an amino and/or a nonionic surfactant. The alkylalkoxysilane is present at a level of about one to sixty weight percent of the final solution weight. The surfactants are present at levels of about 0.05 to 25 weight percent of the final solution weight. The useful quaternary ammonium surfactants are alkyltrimethyl or dialkyldimethyl ammonium compounds or quaternary ammonium modified dimethylpolysiloxanes. Amino and nonionic surfactants are used as additives to the quaternary surfactants. The types of nonionic surfactants contemplated herein are alkylamines and alkyl acetylenic alcohols.

  • Patent number: 4792566
    Abstract: There is disclosed a process for the in-vial deposition of 7-(dimethylaminomethylene)amino-9a-methoxymitosane in sterile unit dosage form. A solution of this compound is introduced into a sterile vial in a solution of tertiary-butanol. The tertiary-butanol is then removed, e.g., by evaporation or lyophilization, and the vial is closed by appropriate means. The thus deposited material can contain up to 0.5 mole equivalent of tertiary-butanol as a hemi-solvate and is very stable to heat.

  • Patent number: 4606939
    Abstract: The present invention is concerned with the simultaneous formation and encapsulation of small particles of organic compounds whose solubility in water is greater at a first pH than at a second pH by concurrently precipitating said organic compounds as small particles and forming a coacervate of an anionic (or cationic) surfactant and an amphoteric surfactant. The process is preferably used to prepare a readily soluble encapsulated pharmaceutically active compound.
