Abstract: An attachment mechanism for a gas turbine engine component includes an elongated body having at least first and second ends. A first attachment feature is formed at the first end. A second attachment feature is formed at the second end. The first and second attachment features define attachment points configured to attach a first gas turbine engine component to a second gas turbine engine component. A fan section for a gas turbine engine and a gas turbine engine are also disclosed.
Abstract: A thermal barrier attachment seal for a gas turbine engine component includes a spine having a first surface and a second surface facing opposite the first surface. A first layer of insulation is provided on the first surface. A second layer of insulation is provided on the second surface to provide a thermal barrier seal between a first gas turbine engine component and a second gas turbine engine component. A fan section for a gas turbine engine is also disclosed.
Abstract: An anchor bolt bolt does not easily jump up even if a tire hits a bumping post. A through hole for inserting the anchor bolt into the bumping post is formed by embedding a cylindrical anchor holder. The anchor holder has a cylinder for receiving the anchor bolt and a head for containing the head of the anchor bolt. A plurality of projecting parts, forming a protruding line, prevent the head of the anchor bolt from jumping up. The projecting parts are positioned at the head of the holder. Since the head of the bolt is pressed down from above by the protruding line, the head of the bolt will not jump up over the projecting parts.
Abstract: A manhole cover apparatus including a collar defining an opening with an inner perimeter is provided with a pivotally mounted cover having an outer perimeter greater than the inner perimeter of the collar. A seal is provided to seal between the cover and the collar. Closure structure is provided to secure the free end of the cover to the collar. A threaded bolt is provided to close the cover. A pivotally mounted lever arm is mounted to the bolt for turning of the bolt. An adjustable threaded hinge is provided to adjust the cover in a longitudinal direction relative to the collar. The manhole cover apparatus is useable on pressure containers, such as those used to pneumatically handle particulate material.
Abstract: Each dual wheel assembly on a tractor or trailer system includes outer and inner wheels mounted on a plurality of studs projecting from a hub. The inner wheel is held in place on the studs by a number of flanged cap nuts and the outer wheel is held in place by a number of wheel nuts. When unthreading the wheel nuts to remove the outer wheel, some of the cap nuts invariably remain engaged with the wheel nuts whereas the cap nuts should all remain engaged with the threaded studs during this step. The device disclosed herein is in the form of a ring having a number of hexagonal holes therein corresponding to the number of wheel nuts so that the ring can be placed over those wheel nuts remaining engaged with their cap nuts to prevent rotation of the wheel nuts when each cap nut is individually spun out through the back side of the removed outer wheel.
Abstract: An anti-rotation locking device for threaded fasteners which secure rotating parts subject to vibration, shock and the like. The device comprises a strap member and one or more retainer members. The strap member is positioned under the fasteners and the retainer members each have a toothed opening which is installed over the matching wrenching surface of the fastener. Each retainer member also has an arcuate slot which is positioned above an arcuate tang on the strap member. The tang is lifted, passed through the slot, bent about the bottom of the slot and folded back over the top surface of the retainer member to thereby restrain the loosening of the fastener.
