Abstract: A skin layer of a superconducting tape has a woven mesh structure and is disposed on a surface of a superconducting tape. The skin layer of a superconducting tape solves the problem where a vapor layer generated when a superconductor is in a normal resistive state greatly reduces the efficiency of a heat exchange between the superconductor and liquid nitrogen. Further provided are the superconducting tape and a superconducting coil.

Abstract: A power tool includes a housing that encloses a motor, and a collet configured to be driven to rotate by the motor. The collet defines a drill axis about which the collet is configured to rotate. The power tool also includes a sensor assembly having a front wall with a wall contact surface. The front wall includes a first wall portion and a second wall portion that define a gap therebetween. An object sensor is secured to the front wall proximate the gap. A support member includes a first end portion attached to the front wall and a second end portion attached to the housing. The support member extends from the housing to position the front wall forwardly of the collet such that the drill axis intersects the gap.

The power tool chuck also includes a locking member movable between a fifth position whereat the locking member locks the collar in the third position and a sixth position whereat the locking member does not lock the collar. The power tool chuck also includes a button movable between a seventh position whereat the locking member is forced into the fifth position and an eighth position whereat the locking member is free to move into the sixth position.

Abstract: A corkscrew assembly includes a housing a worm screw assembly, a first gripper, and a second gripper.

The housing includes a sidewall extending from the first opening to the second opening. The sidewall defines a first gripper passage and a second gripper passage. The interior space is interposed between the first gripper passage and the second gripper passage. The worm screw assembly is rotatable in relation to the housing and includes (i) a worm screw member having a pointed first end portion and a second opposite end portion and (ii) a drive member fixed in relation to the second opposite end portion.

Abstract: A battery label having a black appearance and exhibiting flame retardancy properties is described.

Abstract: A process for preparing mist, which includes micro/nano solids or liquids, and a process for forming new materials by mist gas discharge, and also an apparatus for forming new materials. The advantages are: as compared to common gases, mists exhibit broader selection range of elements and compounds and broader range of suitable temperature and pressure. Due to the presence of mist AI(m), in a sealed container, the concentration of A in unit volume of mist is far higher than the concentration of A in unit volume of gas. Under specific conditions, the physical/chemical reactions can be carried out more easily, and new materials can be formed with higher efficiency.

Abstract: A recliner mechanism (10) includes a first member (40) rotatably supported with respect to a second member (60). The recliner mechanism (10) also includes at least one locking arm member (140) movably located between the first and second members. The locking arm member is configured to lock the position of the first and second members with respect to one another. The recliner mechanism further includes an inner ring member for establishing the range of relative motion between the first and second members. The inner ring member is located on either the first or second member. The recliner mechanism further includes at least one disc member (200) located between the locking arm member and a cam member (180). Actuating the cam member engages or disengages the locking arm member to lock and unlock the first and second members. The first and second members have a plurality of stop members formed therein for engagement with a portion of the inner ring member to define the limits of travel of the recliner mechanism.

Abstract: A proton-exchange composite includes a polymer matrix formed from a proton-exchange polymer and ionomer particles distributed therein. The polymer has side chains with ionic groups. The particles have an average particle size of less than 20 nm and include an oligomeric ionomer that interacts with the polymer and attracts the ionic groups on its side chains. The composite may be formed by a method in which an initiator is bonded to silica particulates. The initiator is used to initiate polymerization of a precursor monomer to form a salt form of the oligomeric ionomer bonded to the silica particulates, which is then reacted with an acid to produce the oligomeric ionomer, thus forming the ionomer particles. The ionomer particles are dispersed in a solution containing a solvent and the polymer dissolved therein. The solvent is removed. The residue is cured to form the composite.

Abstract: A latch mechanism includes a latch hook and an anti-chuck latch, the latch mechanism being connected to a removable seat assembly having a seat back movable between an upright and a folded position. When the seat back is in a folded position, the anti-chuck hook of the latch rotates such that the seat may be removed from a striker in the floor of the vehicle. When the seat back is moved from the folded position, a cam is driven to engage a pawl to lock the anti-chuck hook in a position such that the seat may not be removed from the striker bar even when the latch hook is released.
