Pharmaceutical compositions substantially free of impurities are provided comprising a therapeutically effective amount of aminopterin, or a pharmaceutically acceptable salt thereof. Relative to the teachings of the prior art, the disclosed methods and compositions provide unexpecte...

A laminated glass comprising a plurality of glass sheets laminated one on another with an interliner provided between the respective adjacent glass sheets, wherein said laminated glass has at least a first region and a second region, as viewed from the front, and at the second region, said laminated glass has an infrared transmittance higher than the infrared transmittance at the first region.

Electrochemical cells including secondary batteries and fuel cells are provided employing polyanilines having improved reversibility, stability and electrochemical properties. In accordance with a preferred embodiment polyaniline is employed as a cathode active polymer in a secondary battery at a pH between about 1 and 11. In accordance with other embodiment, fuel cells employing polyaniline are provided as are batteries wherein polyanilines are used as anodes.

An electroerosion process and apparatus are used to produce crude electrodes which are shaped thereafter into finished form by wire cutting erosion. The finished electrodes are used in subsequent countersinking of workpieces by electroerosion.

When impedance elements such as FETs are used in attenuators, the elements have linear responses only when the signals attenuated are below certain signal levels. When signal conditions causing the element to operate non-linearly are detected, bootstrapping is applied to reduce the voltage across the element so that the element will operate linearly. The control signal at the gate of the element is then modified to compensate for the increase in effective impedance of the element caused by boots...

An insole employing a sheetlike battery is formed in conformity to the sole of a foot, and includes a positive electrode in the form of sheet densely containing carbon fibers or fine carbon particles, a negative electrode of a metal foil such as aluminum or zinc, and an electrolyte interposed between the two electrodes.

A packaging assembly adapted for labeling includes: (a) a computer printout sheet having through holes in two parallel rows, (b) a flexible plastic sheet extending flatly adjacent one side of the printout sheet and locally bonded to the printout sheet along elongated bond zones extending at least partly about at least one pocket zone located between said two rows of holes. The printout sheet may comprise a paper sheet and a plastic film attached to the paper sheet and in turn heat bonded to the ...

A package includes a container having an upper finish with inner and outer surfaces. The outer surface includes threads adjacent the top of the finish, and the inner surface includes a lower sealing section located solely in a section of the finish spaced downwardly from the upper margin of said finish. A closure for the container includes an inner valve having an outer sealing surface for frictionally engaging only the lower sealing section of the inner finish surface to provide a leak-proof se...

An apparatus, such as a fuel cell powerplant 10 or a boiler 168, having a flow path for an aqueous solution and a method for operating the apparatus are disclosed. The aqueous solution includes water, iron based compounds, and ferric hydrous oxide of a character that retards the deposition of iron based compounds on the interior of the conduit.
