Patent number: 9234596Abstract: A valve with a valve housing for controlling the liquid flow in a plant for central heating is provided. The valve includes an insert part with valve parts for controlling a liquid flow through the valve: a first part and a second part being mutually rotatable. The first and the second parts are provided with complementary through-flow openings that combine to define a common opening area and are configured such that, upon mutual rotation of those valve parts, a larger or a smaller total opening area is provided. The valve includes a closure part which is disposed such that, upon axial displacement, the closure part is capable of completely or partially closing off the total opening area through the through-flow openings.Type: GrantFiled: July 6, 2012Date of Patent: January 12, 2016Assignee: FlowCon International ApSInventors: Gitte Pedersen, Mille Sveje Bøjgaard, Carsten Møller, Bjarne Wittendorff Ibsen

Publication number: 20150198258Abstract: A control valve (1) for controlling liquid flow in a heating and/or cooling installation under command from an actuator. The control valve (1) comprises a flow regulator with a first annular valve member (20) and a second annular valve member (40) that have an axial overlap. The first valve member (20) is manually rotatable relative to the second valve member (40). The axially overlapping portions of the valve members (20,40) define a first inlet opening (52) with a variable circumferential extent and a second inlet opening (53) with a variable circumferential extent. The first inlet opening (52) is axially offset relative to the second inlet opening (53). A third valve member (24) is axially displaceable by the actuator relative to the first- and second inlet openings (52,53) and defines a first control edge (26) associated with the first inlet opening (52) and defines a second control edge (27) associated with the second inlet opening (53).Type: ApplicationFiled: January 7, 2015Publication date: July 16, 2015Applicant: FLOWCON INTERNATIONAL APSInventors: Bjarne Wittendorff IBSEN, Carsten Enøe MØLLER, Gitte PEDERSEN, Mille Sveje BØJGAARD

Patent number: 8851109Abstract: A detachable handle for adjusting a valve by rotation of a rotatable adjustment element. The handle is provided with a body including a front side having an angular scale, an opposite rear side and a circumferential gripping face. The handle is also provided with a coupling element configured to detachably and operably connect to the rotatable adjustment element. At least a portion of the body along an edge of the angular scale is transparent or open so that an operator can see through the portion of the body. An assembly of a valve and the detachable handle is also provided. The valve is provided with a rotatable adjustment element for adjusting the valve. The valve has a face from which the rotatable adjustment element protrudes. This face is provided with a fixed marker.Type: GrantFiled: September 5, 2013Date of Patent: October 7, 2014Assignee: FlowCon International ApSInventors: Bjarne Wittendorff Ibsen, Mille Sveje Bøjgaard, Gitte Pedersen

Publication number: 20130261813Abstract: The invention relates to a valve system, in particular for controlling the liquid flow in a plant for central heating. The system may comprise one or more valve housings with at least two associated distinct inserts having different flow characteristics. The inserts comprise two types of means with regulable openings that serve as inlet and outlet, respectively, said means being provided with means for regulating the liquid flow, the differential pressure over the openings of that first means being changeable, whereby the area of the openings of the other means is changed to the effect that the differential pressure is regulated. The inserts are furthermore provided with means for the applied change in area by means of an activator that comprises an end which is exposed to the surroundings. A programmable regulator unit provided with motor can be coupled to the end of an activator on the insert.Type: ApplicationFiled: August 30, 2011Publication date: October 3, 2013Applicant: FLOWCON INTERNATIONAL A/SInventors: Bjarne Wittendorff Ibsen, Gitte Pedersen, Mille Sveje Bøjgaard

Patent number: 5855621Abstract: The transfer of a textile dye from a dyed fabric to another fabric during washing or rinsing is inhibited by adding an enzyme exhibiting peroxidase activity or an enzyme exhibiting a suitable oxidase activity to the wash liquor in which said fabrics are washed and/or rinsed. Peroxidase is produced extracellularly by some strains of Bacillus pumilus. The novel peroxidase preparation from B. pumilus is a microperoxidase, i.e. it contains hemopeptide as an active component. The preparation has improved stability at high temperature, at high pH and at high concentrations of hydrogen peroxide. It can be produced without undesired catalase activity.Type: GrantFiled: May 23, 1995Date of Patent: January 5, 1999Assignee: Novo Nordisk A/SInventors: Ture Damhus, Ole Kirk, Gitte Pedersen, Manuel Garcia Venegas

Patent number: 5405414Abstract: In textile printing using a printing paste containing a dye and a biological polymer (or modified polymer) as thickener, removal of the thickener and excess dye is made much more efficient by washing the printed textile in the presence of a suitable enzyme. The enzymatic breakdown of thickener decreases process time as well as the amount of energy and water needed to achieve a satisfactory quality of the textile.Type: GrantFiled: September 9, 1993Date of Patent: April 11, 1995Assignee: Novo Nordisk A/SInventors: Gitte Pedersen, Hans A. Hagen, Lars Asferg, Ebbe Sorensen

Patent number: 5356437Abstract: Dye leached from dyed or printed textiles in an aqueous solution can be decolorized by adding enzymes that utilize hydrogen peroxide or molecular oxygen for the oxidation of organic or inorganic substances, including colored substances, together with a source of H.sub.2 O.sub.2 or O.sub.2. Such enzymes are usually termed peroxidases and oxidases, respectively. This treatment reduces the risk of back-straining (redeposition of dye onto textile) even when less water is used. The enzymatic bleaching of released dyestuff will decrease process time as well as the amount of energy and water needed to achieve a satisfactory quality of the textile, and the color of the waste water is reduced.Type: GrantFiled: October 7, 1993Date of Patent: October 18, 1994Assignee: Novo Nordisk A/SInventors: Gitte Pedersen, Michael Schmidt
