  • Patent number: 4743473
    Abstract: The invention is a method for pressure treatment of wood using compositions comprising aqueous solutions of one or more lanthanide derivatives. Wood is immersed in a pressure vessel containing a lanthanide derivative composition, and hydrostatic pressure is applied. The treatment is carried out at temperatures not exceeding about 95.degree. C., and more preferably at between about 20.degree. C. and about 30.degree. C. Pressure should be greater than about atmospheric, and preferably about 10 psi to about 300 psi.

  • Patent number: 4647401
    Abstract: A process is provided for preparing colloidal dispersions of ceric dioxide in inert organic media which comprises(1) heating(a) ceric dioxide comprising ammonium nitrate or ammonium and nitrate ions in an amount within the range from about 3 to about 14% by weight of the ceric dioxide and a member selected from the group consisting of water, methanol, acetic acid and mixtures thereof in an amount usually from about 10 to about 60 g per mole of CeO.sub.2, sufficient to effect reaction with(b) an organic acid having from about ten to about forty carbon atoms(c) an organic solvent selected from the group consisting of(i) aliphatic and aromatic hydrocarbons, such as petroleum spirits, benzene, toluene, chlorobenzene, chlorotoluene, etc.(ii) aliphatic and cycloaliphatic ethers, such as isopropyl ether or dicyclohexyl ether(iii) aliphatic and cycloaliphatic ketones, such as diisobutylketone or cyclohexanoneat a temperature within the range from about 60.degree. to about 200.degree. C.

  • Patent number: 4365797
    Abstract: A speed compensated timing circuit which detects the velocity of a moving sheet which is to be cut or otherwise processed and which automatically calculates the time delay for actuating a mechanically operating device which controls the cut sheets and which correctly considers and compensates for the delay time of the actuator.
