Abstract: A cargo lock for aircraft cargo loading such as a pallet, designed for optional tension release, in which a detent and toggle detent are mounted for independent pivotal movement relative to a fixed mount and are connected together by a sheer pin for movement of the detent to cargo release position while the toggle detent remains in locked position. When locked, an over-center toggle device prevents releasing movement of the pivoted toggle detent, and a positive locking cam retains the toggle device in locking position. Step-by-step release is provided for a series of lock units upon incremental movement of an elongated control rod.

Abstract: A quick coupling apparatus is provided for interchanging any number of vehicle body units on a single vehicle chassis when each of the body units and the chassis has a pair of parallel longitudinal standardly spaced beams whereby the beams of the body unit will overlie and be supported by the chassis beams when the components are coupled. The coupling apparatus has a plurality of hook-type tabs spacedly positioned on the sides of the body beams and a corresponding number of coupling brackets mounted on the sides of the chassis beams. Each of the coupling brackets being capable of receiving a tab and securing the body unit to the chassis when the body is moved slightly in a longitudinal coupling direction. At least one of the coupling brackets having an enclosing outer plate which forms a retaining slot which can receive a wedge behind the tab for locking the tab and body in position with respect to the chassis.

Abstract: A track guided vehicle is provided which includes laterally projecting transverse guide rollers mounted on support arms extending in a direction parallel to a direction of travel of the vehicle. The guide rollers are adapted to be retractable and extendable to an operating position through a guide arrangement which is directed diagonally upwardly and inwardly with a bilaterally effective operating element being disposed concentrically within the guide arrangement. The transverse guide rollers are elastically flexible in a transverse direction and are adapted to utilize an on board compressed air system to displace the transverse guide rollers and fluidic operating or working element which is constructed for pneumatic pressure application.

Abstract: In an axial flow rotary separator, a transition zone between the infeed section and threshing sections is modified to serve as a stone trap or arresting and ejecting device. Radially aligned inner and outer stone collars carried by the separator rotor and casing respectively, obtrude into the annular space between rotor and casing to define between them an annular slot or gate, decreasing or limiting the annular space so as to arrest the downstream passage of stones greater than a predetermined size. The inside surface of the casing immediately upstream of the stone collars is smooth and free of guide vanes to provide a track over which arrested stones may be propelled by conveyor flights of the rotor. A permanently open outlet in the stone track allows the rotor to eject stones tangentially and centrifugally into a stone sump connected to the casing. The stone sump is easily emptied by opening a door accessible from outside the combine body wall.
