Abstract: A tread for a tire includes a first circumferential main groove, a second circumferential main groove, a third circumferential main groove, and a fourth circumferential main groove. The fourth main groove has a stabilizing structure for increasing tread stiffness. The stabilizing structure has a circumferentially extending wavy subgroove in a radially innermost bottom of the fourth circumferential main groove.

Abstract: Described is a solid wax mitigation barrier for a hearing aid that is cleanable via a simple wiping motion, is not a cause of irritation within the ear canal, and is acoustically transparent. In one embodiment, a wax barrier function is provided by a tube cap for fitting over the acoustic port tube of a hearing aid receiver. The tube cap may be constructed of an elastomeric high tear strength material so as create a small flexible acoustic tube cap that prevents direct ingress of wax into the hearing aid receiver. The design of the cap may also include a bridge that spans an acoustic port inlet so as to block direct material ingress.

Abstract: An apparatus, system and method for reliquefaction of previously regasified LNG are described. A natural gas reliquefaction method includes regasifying LNG onboard a FSRU to form high pressure regasified LNG (HP RLNG), delivering the HP RLNG to a natural gas pipeline that commingles with a natural gas grid, flowing the HP RLNG through a lateral, wherein the lateral diverts HP RLNG from the natural gas pipeline to an expander prior to commingling with the natural gas grid, expanding the natural gas with the expander to obtain low pressure regasified LNG (LP RLNG), liquefying the LP RLNG in a cold box of a nitrogen expansion loop to produce low pressure LNG, and transmitting the LNG to a cryogenic cargo tank onboard an LNG tanker truck.

Abstract: A hydraulic park system includes a spool valve linked to a park mechanism. In some circumstances, a hold-out-of-park mechanism is utilized to hold the spool in position. To avoid wear on the aluminum spool, a steel saddle is inserted onto the spool between two lands such that the hold-out-of-park mechanism engages the steel saddle. The steel saddle is inserted from the side of the spool. To ensure that the hold-out-of-park engages the correct side of the saddle, the saddle must be held in a predefined circumferential position about the bore axis. The saddle is constrained from rotation about the spool axis by abutting flat surfaces on the spool and the saddle. The spool is constrained from rotation relative to the bore by the park mechanism.
