Abstract: A radiant electric heater includes at least first (7) and second (11) adjacent heating zones. The first heating zone (7) includes a first heating element portion (5) and the second heating zone includes a second heating element portion (9). An electrical terminal (19) is provided at a periphery of the heater for connecting the first and second heating element portions to a source of electrical energy. The heating element portions (5, 9) are integral with conjoined ends connected to a first electrical connector (21), with one free end connected to a second electrical (23) connector, and with another free end connected to a third electrical connector (25). The first, second and third electrical connectors include means for connecting to the heating element portions in such a way that the heating element portions are not deflected from their intended path to any substantial extent.

Abstract: A sheet feeder has a supply station wherein signatures fresh from the printing press are stacked. The stack is supported such that the signatures are in an arched, non-planar configuration. A sheet stripper extracts signatures successively from the stack and feeds them in a constant stream to a transfer conveyor. The stripper grips the sheets with a suction device which applies a constant but locally intermittent vacuum. The transfer conveyor carries the signatures to a delivery station. The delivery station includes fingers which arch the signatures. Arching the signatures in the supply and delivery stations prevents rolling of the signatures.

Abstract: An improved composition and process for forming a corrosion-resistant complex oxide coating on a zinc or zinc alloy surface incorporates in an aqueous alkaline composition of pH value greater than 11 at least three complexed polyvalent metals, one of which is trivalent chromium.

Abstract: A composition and method are particularly suitable for applying a corrosion preventive and paint receptive coating to metal surfaces where immersing treatment is impossible or impractical. A brush-on aqueous composition free of reducing agent containing hexavalent and trivalent chromium and at least 5 g/l of silica or silicate together with an organic solvent and thickening agent is applied to the metal surface and dried.

Abstract: A new and distinct variety of Jonathan apple tree is provided which originated as a limb mutation of the Snyder cultivar of U.S. Plant Pat. No. 2,650. The new variety produces attractive red variable-sized fruit which colors approximately 10 to 14 days earlier than the fruit of the Snyder cultivar. Also, the fruit of the new variety exhibits a brighter red appearance and is formed more abundantly and more consistently than the fruit of the Super Jon cultivar of U.S. Plant Pat. No. 5,086.
