    摘要： An electric earth system (10), in particular for a motor vehicle body (15), comprising an earth stud (12), which can be connected to an electrically conductive earth base (14) and has a shaft (24) extending along a longitudinal axis (26) and a flange (18), wherein the earth stud (12) defines a contact surface (28) concentric with the shaft (24), and comprising a covering means (34), which can be connected to the shaft (24) and has a covering surface (42), which at least partially covers the electric contact surface (28) in the connected state. Here, a seal arrangement (46) is arranged between the contact surface (28) and the covering surface (42), such that a sealed-off region (52) is formed between the seal arrangement (46) and the shaft (12), within which region there is located at least part of the contact surface (42).

    摘要： The present invention pertains to a fixture (100) for holding elements (200) during coating operation. The fixture comprises a first member (10), having a front surface and a plurality of first holders (12), a second member (20), having a front surface and a plurality of second holders (22), and an attachment means (30) for removable attachment of the first edge (14) of the first member (10) to the second edge (24) of the second member (20) in a position in which the front surfaces of the first member (10) and the second member (20) are in alignment with each other. The respective first holder (12) is arranged opposite to a respective associated second holder (22) so as to form a holding portion (40) configured to hold the element (200).

    摘要： A mask (100) for an additively manufactured part (102) including a plurality of openings (106, 204) spaced in a surface (110) of the part (102), the mask (100) comprising:
    an attachment ligament (120, 220) configured to integrally couple to the part (102) between the plurality of openings (106, 204) in a cantilever fashion;
    a first cover member (130) including a proximal end (232) first proximal end integrally coupled to the attachment ligament (120, 220) and a first distal end (134) extending at least partially over a first portion (126) of the plurality of openings (106, 204), the first distal end (134) of the first cover member (130) separated from the part (102) by a first spacing;
    a second cover member (140) including a second proximal end (142) integrally coupled to the attachment ligament (120, 220) and a second distal end (144) extending at least partially over a second portion (126) of the plurality of openings (106, 204), the second distal end (144) of the second cover member (140) separated from the part (102) by a second spacing; and
    a detachment member (152, 252, 352) extending from each of the first and second cover members (130, 140),
    wherein the attachment ligament (120) is the sole connection to the part (102).

    摘要： Methods and masks (516, 616, 716) for manufacturing component of gas turbine engines (20) are described. The methods include applying a mask to a protected surface (512, 612, 712) of the component (500, 600, 700), the component having a designated surface (510, 610, 710) to be treated by a shot peen operation. The mask includes a full masking portion (528, 628, 728) configured to prevent a shot peen media from impacting the protected surface. A masking control region (526, 626, 726) is arranged around the designated surface. The masking control region is configured to control an amount of force imparted to the component by shot peen media during the shot peen operation, wherein the masking control region extends from the full masking portion to the designated surface. The designated surface is shot peened with shot peen media to form a compressive stress region (514, 614, 714) within the component proximate the designated surface and a tapering transition (522, 622, 722) of compressive forces within the component proximate the masking control region.
