Abstract: An improved surge arrester includes metal oxide varistors in series with spark gap assemblies arranged such that the MOV elements conduct the low magnitude, steady-state current through the arrester along a path that is separate and distinct from the path through which impulse current is conducted during an overvoltage.

Abstract: A system and method for packaging a plurality of substantially rigid sheet-like members. The system includes apparatus for carrying out the method steps of applying a liquified material to a selected location on a surface of each of the plurality of sheet-like members, cooling the liquified material to form a removable solid element adhering to the selected location on the surface, and stacking the plurality of sheet-like members for packaging such that the solid elements act as interleaving spacers therebetween protecting the sheet-like members from handling and shipping damage.

Abstract: A vehicle seat assembly having adaptability for use as both a side facing seat positioned along the side walls of various model vehicles and as a front facing seat along the rear wall of various model vehicles. The assembly has a plurality of seat modules, the combination being any mix of the single occupant or double occupant variety. Each of the seat modules has a shell-like structure with a back portion and a seat portion, both of which have a concave outer contour configured to receive a human body. Side flanges are integrally formed along the edges of the seat and back portions. A plurality of end arm members are provided and each has a panel section and inwardly extending flanges for supportably contacting the side flanges of the seat module. The arm member flanges have a back portion support flange and a seat portion support flange. Interlocking structure is formed on the rear of the end arm members for engaging interlocking structure on the front of seat mounting adaptor members.

Abstract: A method of compression testing resilient articles comprising the steps of cutting a sample to desired predetermined dimensions, placing the sample in a preflexing machine to provide preflexing at test specifications, and testing the preflexed sample in a sophisticated compression testing machine. The preflexing machine uses a fluid operated cylinder to move a pressure foot member into and out of the sample to compress same the desired number of times, at the desired rate of deflection and desired number of compressions at a fixed total proportion of compression. The machine is automated through a stepping switch driven in steps by a pulse operated drive mechanism which receives pulses from limit switches associated with the movement of the pressure foot. The stepping switch controls the cylinder through solenoids operating a switching valve means to alternately supply fluid pressure on each side of the piston in the cylinder.

Abstract: A corrosion test cell suitable for determining the electrochemical corrosion parameters of metals in corrosive liquid environments. The cell comprises an electrically non-conductive vessel with a plurality of metallic rods connectable to test electrodes, which electrodes extend into the liquid environment contained therein.
