Abstract: A power converter comprises an input port configured to receive a source of power, an output port configured to provide output power, and a bridge circuit coupled to the input port. The bridge circuit comprises a first switch coupled in series with a second switch, and a third switch coupled in series with a fourth switch. A first clamp rectifier is coupled in series with a second clamp rectifier, and the first and second clamp rectifiers are coupled in parallel with the first and second switches. A first clamp capacitor is coupled between the first and second clamp rectifiers, with the first clamp capacitor operative to reduce power loss in the first and second clamp rectifiers. A first resonant inductor is coupled between the first and second switches. The power converter also includes a transformer operatively coupled to the bridge circuit, with the transformer comprising a primary winding and at least one secondary winding.

Abstract: A spoked wheel spinner (20) that is used on an automotive wheel (22) that includes an adapter plate (24) that is mounted onto the automotive wheel (22) with a spinner bearing (26) retained within the adapter plate. A spinner shaft (30) is positioned onto the bearing with a bladed spinner (38) attached onto the spinner shaft. This arrangement permits the bladed spinner (38) to freely rotate independent of the automotive wheel. A cap bearing (50) is located on the spinner shaft (30) with a non-rotating cap (52) interfacing with the cap bearing. The non-rotating cap (52) includes a counter-weight (60) on the bottom edge so that when the automotive wheel (22) is rotating, the cap remains in a relatively fixed position without rotating. A cover (64) having indicia is attached to the cap permitting writing, symbols, designs and the like to be displayed.

Abstract: A method comprises (A) defining a first experimental space comprising factors of at least two mixtures with at least one common factor, (B) defining a second experimental space by deleting duplicate factor combinations from the first experimental space and (C) conducting an experiment on the second experimental space. A system comprises a processor that (A) defines a first experimental space comprising factors of at least two mixtures with at least one common factor and (B) defines a second experimental space by deleting duplicate factor combinations from the first experimental space. The system also comprises a reactor and evaluator to select a best case set of factors from the second experimental space by a combinatorial high throughput screening (CHTS) method to select a best case set of factors from the second experimental space.

Abstract: A photocurable composition, including (a) an epoxy resin component; (b) a (meth)acrylate; (c) a cationic photoinitiator; (d) a radical photoinitiator; and (e) a phosphite component. A method of making a 3-D object from such a composition, and the resulting 3-D object.

Abstract: A heat-transfer label suitable for use in decorating polyethylene-coated glass articles. In a preferred embodiment, the label is capable of withstanding pasteurization conditions on a polyethylene-coated glass article and includes (a) a support portion in the form of a sheet of paper overcoated with a release layer of polyethylene, (b) a skim coat of wax overcoated onto the polyethylene release layer and (c) a transfer portion, the transfer portion including a cross-linked phenoxy protective lacquer layer printed onto the skim coat, a polyester ink layer printed onto the protective lacquer layer, a first adhesive layer printed onto the ink layer and onto any exposed portions of the underlying protective lacquer layer, and a second adhesive layer printed onto the first adhesive layer.

Abstract: A heat-transfer label well-suited for use in decorating silane-treated glass articles. In a preferred embodiment, the label exhibits good scuff resistance, is capable of withstanding pasteurization conditions on a silane-treated glass article and includes (a) a support portion in the form of a sheet of paper overcoated with a release layer of polyethylene, (b) a skim coat of wax overcoated onto the polyethylene release layer and (c) a transfer portion, the transfer portion including a cross-linked phenoxy protective lacquer layer printed onto the skim coat, a polyester ink layer printed onto the protective lacquer layer, and an adhesive layer printed onto the ink layer, as well as onto any exposed portions of the underlying protective lacquer layer and onto a surrounding area of the skim coat. The cross-linked phenoxy resin comprises a solvent-soluble phenoxy resin of the formula ##STR1## wherein the solvent-soluble phenoxy resin is cross-linked by a melamine formaldehyde resin.
