Patent number: 6596670Abstract: The use is disclosed of at least substantially water-insoluble ethers which are fluid and/or at least plastically deformable at working temperature and have flash points of at least 80° C., of mono- and/or polyfunctional alcohols of natural and/or synthetic origin or corresponding solutions of such ethers in ecologically acceptable water-insoluble oils as the dispersed oil phase of water-based O/W-emulsion drilling fluids which are suitable for the environmentally acceptable development of geological formations and which contain, if desired, insoluble, finely particulate weighting agents for the formation of water-based O/W-emulsion drilling muds and/or further additives, such as emulsifiers, fluid-loss additives, wetting agents, alkali reserves and/or auxiliary substances for the inhibition of drilled rock of high water-sensitivity.Type: GrantFiled: March 3, 1993Date of Patent: July 22, 2003Assignees: Cognis Deutschland GmbH & Co. KG, Baroid LimitedInventors: Heinz Mueller, Claus-Peter Herold, Stephan von Tapavicza, Gerhard Stoll, Rainer Jeschke, Johann Friedrich Fues

Patent number: 6165946Abstract: The invention relates to a process for facilitating the disposal of flowable and pumpable working fluids based on emulsifiers containing W/O invert emulsions--more particularly corresponding auxiliaries of the type used in geological exploration, such as oil-based w/o invert drilling muds--and for the simplified cleaning of solid surfaces soiled therewith, if desired using flowable spraying aids, the process being characterized in that, by selecting and adapting the emulsifiers/emulsifier systems to the oil phase of the invert emulsion, temperature-controlled phase inversion is achieved at temperatures below the in-use temperatures of the w/o invert emulsions, but above the freezing point of the aqueous phase and in that disposal and cleaning are carried out at temperatures in and/or below the phase inversion temperature range.Type: GrantFiled: April 30, 1999Date of Patent: December 26, 2000Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Heinz Mueller, Claus-Peter Herold, Thomas Foerster, Stephan von Tapavicza, Johann-Friedrich Fues

Patent number: 6022833Abstract: The invention relates to flowable and pumpable multicomponent mixtures based on a multiphase mixture of water and oil containing emulsifiers and, if desired, other soluble, emulsifiable and/or dispersible auxiliaries for their use in exploration by drilling and/or for the further treatment of the wells thus drilled. The invention is characterized by the use of emulsifiers or emulsifier systems which, in the particular multicomponent mixture in question, lead to temperature-controlled phase inversion at a phase inversion temperature (PIT) in a temperature range of which the upper limit is so far below the working temperature of the multicomponent mixture in geological exploration that the water-based part of the multicomponent mixture is present as a disperse (invert) phase in the continuous oil phase (w/o invert emulsion) while the lower limit of this temperature range enables the multicomponent mixture to be converted into an o/w emulsion with a continuous aqueous phase.Type: GrantFiled: September 18, 1997Date of Patent: February 8, 2000Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Heinz Mueller, Claus-Peter Herold, Thomas Foerster, Stephan von Tapavicza, Johann-Friedrich Fues, Marcus Claas

Patent number: 5858169Abstract: A process for separating a multi-component mixture containing solid or liquid organic components by treating the mixture with a gaseous entraining agent comprising a superheated carrier fluid containing a lower monohydric alcohol or a lower monohydric alcohol and water to cause constituents of the multi-component mixture to become entrained in the gaseous entraining agent, and separating the gaseous entraining agent containing constituents of the multi-component mixture from the multi-component mixture.Type: GrantFiled: May 23, 1996Date of Patent: January 12, 1999Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Wilfried Raehse, Johann-Friedrich Fues, Karl-Heinz Buettgen, Ovidiu Dicoi

Patent number: 5552454Abstract: The invention relates to at least partly resorbable materials for replacing and/or joining bones and auxiliaries for implanting prosthesis material in living bone tissue which contain as their essential components body-compatible ceramic materials in admixture with body-resorbable oligomers and/or polymers of lower hydroxycarboxylic acids, more particularly glycolic acid and/or lactic acid (resin component) and which are characterized in that the resin component is produced using molecular-weight-regulating co-reactants from the class of mono- or polyfunctional carboxylic acids or corresponding alcohols and is substantially freed from free carboxyl groups.Type: GrantFiled: November 4, 1994Date of Patent: September 3, 1996Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Josef Kretschmann, Wolfgang Ritter, Johann-Friedrich Fues
-
Patent number: 5537759Abstract: A process for the drying of water-containing materials which are suitable for use as wetting agents, detergents or cleaning products. An aqueous solution, emulsion or suspension of the materials is dried using superheated steam as the drying gas wherein the drying gas is recycled to the drying zone after removal therefrom of evaporated water and the energy required for the evaporation of water is supplied to the superheated steam by heat exchangers.Type: GrantFiled: October 12, 1994Date of Patent: July 23, 1996Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Wilfried Raehse, Johann-Friedrich Fues, Otto Koch, Joerg-Martin Schmidt

Patent number: 5482717Abstract: The invention is a resorbable, viscous to solid wax for the mechanical staunching of blood on hard body tissue, particularly bones, based on oligomers of glycolic acid and/or lactic acid and derivatives thereof with monofunctional and/or polyfunctional alcohols and/or corresponding carboxylic acids. The new waxes are characterized by containing body-compatible salts of organic and/or inorganic acids which are formed by corresponding reaction of any free carboxyl groups present in the oligomer wax and/or are incorporated in the wax in homogeneous distribution as added salts.Type: GrantFiled: March 10, 1994Date of Patent: January 9, 1996Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Johann-Friedrich Fues, Wolfgang Ritter

Patent number: 5318956Abstract: The use is disclosed of water-dispersible esters, which are fluid or at least plastically deformable at working temperature and have flash points of at least 80.degree. C., from saturated and/or unsaturated carboxylic acids with up to 36 carbon atoms and mono- and/or polyhydric alcohols, as at least the main constituent of the dispersed oil phase of water-based O/W-emulsion drilling fluids which are suitable for the environmentally friendly development of geological formations and which contain, if desired, insoluble, finely particulate weighting agents for the formation of water-based O/W-emulsion drilling muds and/or further additives, such as emulsifiers, fluid-loss additives, wetting agents, alkali reserves and/or auxiliary substances for the inhibition of drilled rock of high water-sensitivity.Type: GrantFiled: April 29, 1993Date of Patent: June 7, 1994Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Heinz Mueller, Claus-Peter Herold, Stephan von Tapavicza, Johann Friedrich Fues
