Abstract: System for carrying cargo in a passenger aircraft having containers, floor panels, seat tracks, and cargo locks. Containers are dimensioned to pass through a passenger door of an aircraft, fit under the overhead luggage racks of the aircraft and, when one container is positioned on each side of the passenger cabin of the aircraft, leave sufficient space between the containers to permit an aisle of the minimum size required by aviation safety regulations. The containers are sufficiently strong that, when loaded with cargo and fastened in place by the seat tracks and cargo locks, the containers will contain the cargo when subjected to accelerations which containers in passenger compartments must withstand under aviation safety regulations.

Abstract: A kitchen article having a body, the body having a bottom sidewalls, a supporting structure formed in the body for supporting a kitchen implement over a top of the body, a bowl formed in an upper portion of the body, a spout formed at one location in an upper portion of a wall of the bowl and extending to a lip in the exterior of the body, and a chamber below a lower surface of the bowl and above the body. The body has provision therein for access to the chamber, the chamber being large enough to accommodate an implement of the proper size to fit on the supporting structure.

Abstract: A holder for grater boards and the like includes a hollow body having a top wall, a bottom wall, a side wall, and an interior partition wall, the side wall, the bottom wall and the partition wall defining a main chamber having an opening in one side thereof, a planar surface formed in the side wall of the body opposite to the opening, elements on the edges of the opening for removably securing a grater board over the opening, a handle in an upper portion of the hollow body, a rubber foot attached to the exterior of the hollow body at the bottom thereof, and a window in the main chamber extending substantially the height thereof.

Abstract: A method for drying articles flowing through a drying chamber by introducing heated air into the drying chamber. In normal steady-state operation, the inlet and outlet temperatures of the air are monitored, and the inlet temperature is maintained at a normal operating inlet temperature. When the inlet and outlet temperatures approach each other, a stoppage or reduction of the normal steady-state flow of the articles is indicated, in response to which the inlet temperature is reduced to an energy saving temperature. After the inlet temperature is reduced to the energy saving temperature, monitoring of the inlet and outlet temperatures continues. When the difference between the energy saving inlet temperature and the outlet temperature increases, resumption of the normal steady-state flow of the articles is indicated, and in response thereto the inlet temperature is increased from the energy saving temperature to the normal operating inlet temperature.

Abstract: An introducing needle having two lumens is disclosed. The lumens originate at the sharpened end of the needle in a parallel relationship. The first lumen is rectilinear along the entire longitudinal length of the needle and is adapted to engage a syringe barrel at the needle's hub end. The second lumen is rectilinear along the substantial longitudinal length of the needle and diverges from the first lumen at the needle's hub end. In operation, after a blood vessel is punctured by the sharpened end of the needle, a "flash" of blood is drawn through the first lumen and a guidewire is thereafter inserted through the diverging second lumen without disengaging the syringe barrel from the first lumen. In this manner, manipulation of the needle during insertion of the guidewire is substantially reduced, thereby reducing patient discomfort, trauma to the vein, and the possibility of movement of the needle from the initial puncture location.

Abstract: The invention discloses a novel head closure apparatus for shell and tube-type heat exchangers. The disclosed apparatus is substantially resistant to thermal stress cracking in that it has an internal closure chamber configured to withstand and dissipate thermal stresses caused by rapidly changing thermal gradients. The apparatus also provides for full access to the entire interior volume of the head closure and to the entire area of the head closure inner tubesheet surface in order to facilitate maintenance and repairs. The invention also discloses a compact and efficient retaining key apparatus for constraining the end-cover of a cylindrically-shaped head closure member against internal working pressures. The apparatus enables substantial reductions in the masses of the retaining keys, the head closure member, and the end-cover, which results in the head closure apparatus being simpler and more economical to manufacture and maintain.
