An article of footwear, lacing engine, and method includes a motor, a transmission operatively coupled to the motor, and a lace spool. The lace spool is operatively coupled to the transmission and includes a top lace groove in a top surface of the lace spool and a circumferential channel, wherein the lace is configured to be inserted in the top lace groove and be taken up around the circumferential channel based on a turning of the lace spool from action by the motor and transmission. A fastener is configured to couple the lace spool to the transmission and is inserted into the lace spool via the top surface, the fastener having a head having a head width sufficient to partially cover the top lace groove, leaving a top gap having a gap width less than a thickness of the lace.

A system for producing a vehicle body assembly in a manufacturing facility is provided. The system includes a forming station configured to form a vehicle body member from a metal material; and an assembly station configured to assemble the vehicle body member with at least one additional vehicle body member to form the vehicle body assembly. The forming station and the assembly station are disposed, in the manufacturing facility, at a predetermined distance from each other, and wherein the predetermined distance is in the range of 0-50 feet.

A composite multi-axial impact protection liner for a helmet is provided that reduces rotational acceleration, rotational strain rate, and rotational strain that cause concussions. In a protective helmet so equipped, one or more layers of fluid polymer, including strain thinning and strain thickening polymers, are positioned between the wearer's head and a hard helmet shell. The liner offers greater injury protection, performance, and personal comfort using the rate dependent and combined effect of strain thinning and strain thickening of fluid polymer layers.

A method protects a field joint of a pipeline, where chamfered edges of thermally-insulating parent coatings on conjoined pipe lengths are in mutual opposition about a longitudinally-extending gap. The method includes manufacturing an hourglass-shaped inner layer around the pipe lengths, which layer may be moulded. The inner layer extends longitudinally along the gap between the chamfered edges and at least partially overlies the chamfered edges. A thermally-insulating solid insert is assembled from two or more parts to lie in the gap surrounding the inner layer, and pressure is applied radially inwardly from the insert to the inner layer. An outer layer of molten material is manufactured around the insert to form a watertight barrier and to form one or more melted interfaces with the inner layer. Corresponding field joint arrangements are also disclosed.

A different material joining structure has: a first panel made of a first metal material; a second panel made of a second metal material that has a higher conductivity than that of the first panel, is different from the first metal material, and at least a part of which faces the first panel; and a rivet for joining the first panel and the second panel, wherein the rivet is made of the first material, and includes a head portion that is embedded in the second panel in a non-penetrating manner and a bottom portion that abuts on the first panel, and wherein a nugget portion as a joint portion is disposed between the first panel and the bottom portion, the nugget portion being formed by resistance welding the rivet to the first portion with the rivet disposed between the first panel and the second panel.

A method may be used to produce a component that includes at least two different materials. The method may involve providing a hardenable planar or preformed steel sheet or steel profile, completely or partially heating the steel sheet or steel profile to the austenitic temperature, inserting the heated steel sheet or steel profile into a first tool for hot forming and/or press hardening the steel sheet or steel profile to give a completely or partially hardened steel workpiece. In the course of the hot forming and/or press hardening at least one jog is made in the steel sheet or the steel profile. The jog may serve for fastening at least one second material thereto.”

An iron-based sprayed coating for coating a bore inner surface of a cylinder block for an internal combustion engine. A coating surface contains pits, its pit amount is within a range of 0.01% to 2.1%, and an average roughness Ra of this coating surface is within a range of 0.01 μm to 0.15 μm. The cylinder block for an internal combustion engine includes a bore having this iron-based sprayed coating on its inner surface, and a cylinder block body having the bore. A sliding mechanism for an internal combustion engine includes this cylinder block for an internal combustion engine and a piston slidable with the bore of this cylinder block. The piston has a piston ring, and the piston ring has a chromium coating, a chromium nitride coating, or a diamond-like carbon coating at a sliding part with the bore.

A tool aligns a snap-ring with a sink-flange tailpiece of a garbage disposal, and is used to slide the ring up along the tailpiece outer surface to a groove. The tool expands the snap-ring, prior to installation on the tailpiece, by an expansion mechanism, to a diameter that is slightly larger than the outer diameter of the tailpiece. The tool receives a stack of conventional disposal components on the tool top end, so the user with one hand can raise the tool and the stack to the tailpiece, and the fingers and thumb of the one hand can push the expanded snap-ring upward to reach and snap into the groove. The expansion mechanism may be a tapered tool bottom end, an expander tab, and/or an adaptation wherein the tool is reduced in diameter to fit inside a relaxed snap-ring and then increased in diameter to expand the snap-ring.

A method of manufacturing a bridge-type ball screw (1) with a bridge member (5) fit into a nut bridge window (6). The bridge member (5) has a linking groove (5a) with a rolling track that acts as a circulating path. After the bridge member (5) is fit into the nut bridge window (6), a cylindrical mandrel (8), with projections (9), is inserted into the nut (3). An upper die (10) restricts the upper surface of the bridge member (5) and is lowered while the nut (3) is held between the upper die (10) and the mandrel (8). A connection part is subject to plastic working by the projections (9) of the mandrel (8). The bridge member (5) is simultaneously deformed by the upper die (10) to secure the bridge member (5) into the nut bridge window (6).
