Abstract: A fastening arrangement is provided for attaching components such as headliners, overhead consoles, or the like to vehicles. The arrangement includes a shaped slot in a first member which has a retaining end, a releasing end, and a neck with inclined protrusions therebetween, and a fastener attached to a second member and having an engaging leg portion constructed to be securely inserted directly and normally into the retaining end of the slot. Once installed, the fastener is securely held in the slot, but is releasable by forcing the engaging leg portion of the fastener past the inclined protrusion into the releasing end of the slot, whereat the component can be removed for servicing or repair. Also, a headliner is provided including a central portion with a perimeter, and a folded edge portion connected to the perimeter that presents a finished side along the perimeter so that the headliner can be installed into the vehicle roof without subsequent parts required to cover the perimeter.

Abstract: A weight-balancing system for a farm implement, such as a disk harrow with foldable wings operated by wingfold cylinders, includes a selective control valve for controlling fluid communication to the head and rod ends of the wingfold cylinders. A pair of pressure-reducing/relieving valves permit individual adjustment of the pressures in both the head and rod ends to achieve the desired balance. In a preferred embodiment, a pilot-operated, two-position valve is connected between the rod ends and one of the pressure-responsive valves. The two-position valve is operated by pressure signals generated by a flow-responsive switching valve connected between the two-position valve and the selective control valve. The switching valve and the two-position valve cooperate to block the pressure-controlled outlet of the one pressure-responsive valve and the rod ends and to bypass return fluid flow from the rod ends to sump when the cylinders are being extended.
