Ulrich Steffen has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20240071162
    Abstract: An automated transaction machine (“ATM”) can include a note input/output port, an escrow unit, and an upper transport. The escrow unit can receive and hold currency notes. The upper transport can transport currency notes among the note input/output port and the escrow unit. The escrow unit can include a drum and first and second web-supply spool assemblies. The drum collects and releases currency notes relative to the upper transport, is rotatable about a first axis, and has a variable radius including minimum and maximum radii. Each web-supply spool assembly includes a spool and a web and can rotate about respective second and third axis parallel to and spaced from the first axis. A fourth axis can extend normal to and intersect both of the second and third axis and can be closer to the first axis than the maximum radius of the drum.

  • Patent number: 4357445
    Abstract: A process for the production of cross-linked graft copolymers by the radically initiated precipitation copolymerization of an ethylene/vinyl ester copolymer as graft base and a mixture to be grafted of one or more aromatic monovinyl compounds, acrylonitrile and/or methacrylonitrile, a cross-linking agent containing two or more carbon-carbon double bonds, and, optionally, another monoolefinically unsatured copolymerizable monomer wherein the ungrafted base is precipitated by the addition of a precipitating agent simultaneously with the precipitating cross-linked graft copolymer.

  • Patent number: 4329267
    Abstract: A process for the preparation of dispersions of optionally cross-linked ethylene-vinyl ester graft polymers wherein an ethylene-vinyl ester copolymer is used as graft substrate and a vinyl ester of a C.sub.1 -C.sub.18 carboxylic acid and/or a C.sub.1 -C.sub.10 -alkyl ester of acrylic and/or methacrylic acid are used as a graft monomer which is polymerized, optionally together with a cross-linking agent having two or more C--C double bonds, in organic solution until at least 25% by weight of the graft monomer has been reacted, the reaction product is converted into a stable finely divided dispersion by the addition of a precipitating agent under the action of shearing forces and polymerisation is completed before, during or after the formation of the dispersion.

  • Patent number: 4241197
    Abstract: Graft copolymers consisting ofA. from 10 to 80% by weight of an ethylene/vinyl ester copolymer containing from 1 to 75% by weight of vinyl ester; andB. from 90 to 20% by weight of a grafted monomer mixture ofI. from 5 to 50% by weight of acrylonitrile and/or methacrylonitrile;II. from 94.9 to 35% by weight of one or more aromatic monovinyl compounds, andIII. from 0.1 to 15% by weight of (meth)acrylic acid or a (meth)acrylic acid alkyl ester;the sum of components A and B and of components I to III amounting respectively to 100% by weight.
