Disclosed are an article of safety footwear, a method of making the same, and a safety toe cap assembly adapted to be used in making such footwear. The article of safety footwear has a rigid, crush-resistant toe cap located in its toe region and having its outer surface bonded to the interior of the upper of the footwear article, a cushioning layer of resilient, compressible cellular (open-celled or closed cell or having both open and closed cells) cured elastomeric polymeric material, typically...

Photomasks and method of fabrication thereof, whereby a thin layer of germanium is deposited to a substrate which may be then etched in a pattern to provide a photomask or information storage device. In the fabrication method, a substrate is carried by belt through a first inert gas curtain into a furnace containing a mixture of suitable gases for causing the deposition of germanium onto the heated substrate, and there outward through a second inert gas curtain into a cooling region. The use of ...

An electrode coating having the formula A.sub.2 BO.sub.6, where A represents trivalent elements having anionic radius comprised between 0.50 and 0.73 Angstrom and where B represents hexavalent elements having an ionic radius comprised between 0.50 and 0.70.

A candle having a shaped, thermoplastic blend with a wick extending therethrough. The thermoplastic blend includes ethylcellulose and at least one glyceride. Preferably the blend is transparent and preferably it also incorporates a minor amount of an additive, such as an oxa- or oxo- group containing compound, or even a heavy petroleum hydrocarbon.

A pilot operated three-way diaphragm valve having a vent valve including a closed end metal cylinder having an open end to receive the three-way valve exhaust. The cylinder has holes through it. A rubber tube is assembled over the cylinder. The cylinder and tube have an interference fit. The tube seals the cylinder holes shut until the differential pressure across the vent valve to cause venting rises to a predetermined pressure. The tube also has holes which do not lie in registration with thos...

Building constructions are disclosed in which the framework comprises preformed, reinforced concrete columns, beam modules having angularly disposed beam portions, and intermediate beam members. Means are provided to interconnect the reinforcements of vertically aligned columns through the module supported by one column and in support of another column.
