Abstract: A method of properly aligning a sliding side door on a vehicle includes first preparing a prototype vehicle and determining how far out of alignment the door is to the body of the prototype vehicle. This amount of misalignment is then used to adjust the attachment position of an anchor plate to a sliding side door of the vehicle, so that the anchor plate is attached at a desired position to the production vehicle, which causes there to be no misalignment between the sliding side door and the body of the production vehicle. A jig is used to hold the anchor plate at the desired location while welding the anchor plate to the door. A roller assembly is then attached to the anchor plate and to a rail on a body of the vehicle.

Abstract: A seat ring assembly in a ball valve or a gate valve provides a primary metal-to-metal seal and a secondary metal-to-synthetic resin seal. The primary seal is accomplished by direct contact between the valve body and the interior conical surface of the seat ring. The secondary seal is made by contact between the valve body and a synthetic resin seat ring insert. The synthetic resin seat ring insert is slidably inserted into an annular groove cut into the conical surface of the seat ring. A compressible seal member is inserted between the bottom surface of the annular groove and the synthetic resin seat ring insert to urge the seat ring insert into contact with the valve body. An additional compressible seal member is inserted into an annular space defined by an inner cylindrical surface of the valve casing and a facing cylindrical surface of the seat ring.
