Abstract: A stowage compartment to be mounted in an overhead supporting structure of an aircraft includes a lower compartment section for receiving articles to be stowed and an upper compartment section serving as an outer cover for the lower compartment section. One of the compartment sections is fixed to the supporting structure, and the other is pivotal to a closed position or to an open position with respect to the fixed compartment section. The compartment further includes an inner pivotal cover between the lower compartment section and the upper compartment section, and an inner cover locking mechanism having a handle which is manually accessible to a user, for releasing the inner cover locking mechanism to permit pivoting the inner cover with respect to the lower compartment section, only when the outer cover is in its open position.

Abstract: A chair construction for passenger vehicles having a table pivotally mounted to the backrest to either a folded vertical position against the backrest or to an operative horizontal position for use by the occupant of the seat directly behind the respective seat in the line, characterized in that an article storage compartment is carried by the table such that the article storage compartment minimizes interference with the occupant of the behind seat in the folded vertical position of the table thereby providing more comfort and/or enabling closer spacing of rows of the chairs one behind the other.

Abstract: Transfer apparatus for transferring an article holder, particularly a cart carrier, from one location to another location in a compartment, includes a carriage movable longitudinally of a framework in the compartment, a drive for the carriage, a coupling device carried by the carriage, a locking device carried by the framework, and an actuator which actuates the coupling device and the locking device to either a locking position or to a released position with respect to the article holder. The actuator includes an actuator member movable to a plurality of positions when actuated, including: (a) a first position wherein the locking device is in its locking position and the coupling device is in its released position; (b) a second position, wherein the locking device is in its locking position and the coupling device is in its coupling position; and (c) a third position, wherein the locking device is in its released position, and the coupling device is in its coupling position.

Abstract: A vehicle cabin construction includes a storage Compartment in the space between the ceiling and outer cabin wall extending longitudinally of the vehicle cabin for storing article holders, an elevator for lowering the article holders from the storage compartment to the deck, and for raising the article holders from the deck to the storage compartment, and longitudinal transfer means engageable with the article holders for moving them longitudinally from or to different locations in the storage compartment on a plurality of roller transfer members.

Abstract: An aircraft cabin construction includes a cart-storage compartment in the space between the ceiling of the passenger compartment and the upper fuselage wall for storing food-serving wheeled carts; and an elevator having a platform and a drive for lowering the carts from the cart-storage compartment to the deck of the passenger compartment, and for raising the carts from the deck to the cart-storage compartment.

Abstract: An aircraft fuselage construction includes a track overlying and parallel to the aisle, a food carrier having wheels on its bottom engageable with the deck, and a guiding member engageable with the track for guiding the movement of the food carrier along the aisle.

Abstract: A food storage and delivery system for passenger vehicles having a plurality of seats separated by at least one aisle includes a rail mounted to the top of the vehicle and extending parallel to the aisle along its length, a carriage suspended from the rail, a food container on the carriage and movable along the length of the aisle, and a horizontal platform laterally of the rail for holding a plurality of the food containers, each alignable with the carriage for transferring the food container thereto.

Abstract: A method and apparatus are described for diagnosing the condition of oil-wetted parts subject to wear, wherein a specimen of the used oil from the part is extracted, and a plurality of samples are separated according to the different mobility rates of its particles through a liquid medium during the centrifuging of the specimen through the liquid medium for a predetermined period of time. The samples are then analyzed to determine their compositions, thereby providing an indication of the identities of the wearing parts and their rates-of-wear. In one described embodiment, the specimen is centrifuged for a sufficiently long predetermined time to stratify the particles according to size and density; and in a second described embodiment, the specimen is centrifuged for a plurality of short predetermined time periods during each of which a sample of the particles passing the complete length of the liquid medium is removed and analyzed.
