摘要:
The present invention provides a storage stable microemulsion formulation for modified lecithin as well as other materials. For modified lecithin, the microemulsion contains at least one metal chelate complex, at least one surfactant such as an anionic surfactant, modified lecithin, water, and optionally at least one alcohol. For other materials, the microemulsion contains all above plus one or more other materials wherein modified lecithin can be replaced by unmodified lecithin. Further provided are methods of making and using the above microemulsions.

The rectifier arrangement, preferably for a three-phase generator for a motor vehicle, has at least one power diode of positive polarity and at least one power diode of negative polarity assigned to respective half waves of each phase of the three-phase current and a cooling arrangement for the power diodes, the power diodes of like polarity being arranged on respective heat sinks in an electrically and thermally conductive fashion, and the heat sinks being sandwiched together with at least one electrically insulating part (32) which contains the electrical conductors between the diodes and the three-phase winding. The electrically conductive connections of the power diodes (12, 14) of positive and negative polarity to the phases (U, V, W) of the three-phase generator extend within the electrically insulating part (32) so that electrical contact is made with the power diodes (12, 14) of positive and negative polarities in respective cavities (40, 44) in the insulating part (32) via in each case one spring element. A punched grid (34) for each of the phases (U, V, W) extends in the cavities and includes conductor tracks (50) and spring elements (48, 49) for making electrical contact between pairs of power diodes of opposite polarity and each phase.

The invention is a bracket for installing a gutter cover for ducting rainwater to a rainwater gutter, where the gutter cover prevents debris from entering the gutter. The bracket is roughly shaped like three extended fingers, where each finger is a strut. The struts converge at a junction. The various struts are a lifting strut that supports the leading hooked frontal edge of a gutter cover, a stabilizing strut that has a hooked end that interlocks with the hooked edge of a frontal rim of a gutter trough, and a bracing strut that is a leg stemming from the junction to a bottom portion of the gutter.

摘要:
A structure for mounting a gutter cover on a new rain gutter or an existing rain gutter, wherein the gutter cover prevents debris from entering the gutter. The cover support structure is comprised of a lifting strut that supports the leading hooked frontal edge of a gutter cover, two stabilizing struts that interlock with the hooked edge of a frontal rim of a gutter trough, a connecting strut that connects the lifting strut to the stabilizing struts, and a junction where the lifting strut and stabilizing struts converge.
