The coating composition includes (1) a polymerizable compound with an unsaturated bond, and (2) a free radical photoinitiator. The dispensed coating composition is then subjected to actinic radiation for a duration of less than 0.7 seconds.
US10574013B2	Brush cage for motor vehicle starter, and corresponding brush holder, electric motor and motor vehicle starter The invention relates mainly to a brush cage (13) for a brush holder (10) of an electric motor comprising:—two lateral walls (26) and a connecting wall (28) connecting the two lateral walls (26),—in which cage at least one of the lateral walls (26) has an opening (43) for the passage of a spring arm,—the lateral wall (26) comprising the opening (43) having a length (L0) measured between a first end (51) intended to be furthest from a commutator and a second end (52) intended to be closest to the commutator, wherein the opening (43) comprises at least a first portion (431) between the two ends (51, 52) which widens out towards the second end (52).
US10574006B2	Multipolar connector with circular contacts Connector comprising a base (1) of substantially cylindrical form and a plug (2), connectable to the base in a removable manner to the base (2), in which are disposed a plurality of contacts (3); the base (1) comprising a conducting face (4) on or in which is disposed at least one conducting track (5) forming at least one arc of a circle whose centre (6) is substantially coincident with the centre of the conducting face (4); said track (5) furthermore being disposed in such a way as to permit a mechanical electrical coupling with one of said contacts (3).
US10574003B2	Electrical connectors with reinforced structure A pair of locking arms unitarily extends forwardly from opposite inner edges of the transverse bar in a perpendicular manner and are spaced from two opposite side edges of the shielding plate but abutting against the corresponding side edge of the tongue portion. A front end region of each locking arm further grasps a front edge of the tongue portion and optionally connected to the corresponding grounding terminals. The two opposite ends of the transverse bar are also optimally mechanically and electrically connected to the corresponding grounding terminals. The pair of locking arms may extend from two opposite side edges of the shielding plate or from two opposite end regions of the front edge of the shielding plate alternately.
US10574000B1	Grounding structure for an electrical connector An electrical connector includes a front housing and a contact module received in a cavity of the front housing having a frame assembly including a dielectric holder holding signal contacts. Each signal contact has a mating end and a terminating end. A ground shield is coupled to the dielectric holder for shielding the signal contacts. The ground shield has a ground pad at the mating end, mating beams extending forward from the ground pad for mating with corresponding header ground shields and tie bars extending between corresponding mating beams.
