Abstract: A process for producing titanium metal sponge from an exothermic reaction between titanium tetrachloride vapor and molten magnesium vapor, and reclaiming reactive metals from by-products of the exothermic reaction.

Abstract: A rotary type lubrication pump for a vehicle transfer case and a method of producing the lubrication pump, the lubrication pump having an inner gear and an outer gear produced by molding a synthetic polymer, and a pump body and a pump cover produced by stamping steel.

Abstract: A speed sensor tone wheel has a plurality of serrations formed on an inner periphery for engagement with an axially extending annular surface formed on a wheel bearing seal support. The tone wheel is mounted on the support and an outwardly facing surface of the serrations is coined to force the inner ends of the serrations into contact with the annular surface to prevent relative rotation between the tone wheel and the support. Tabs can be formed in the outer periphery of a radially outwardly extending flange of the wheel bearing seal support for extending through open spaces between the serrations and engaging a surface of the tone wheel to trap the tone wheel between the support flange and the tab. Alternatively, an indentation can be formed in the flange to project into an associated one of the serrations.

Abstract: A process for producing titanium metal sponge within a closed cell system involving the electrical decomposition of molten magnesium chloride into magnesium metal and chlorine gas within a closed cell to form said magnesium metal as a molten layer upon said magnesium chloride; terminating said electrolytic decomposition, and subsequently; directly contacting titanium tetrachloride with said layer of magnesium metal for effecting a reduction reaction therebetween within the same closed cell to form titanium metal sponge and magnesium chloride and removing said titanium metal sponge from said closed cell. The chlorine gas by-product can be used to form titanium tetrachloride from a titanium ore/coke mixture.

Abstract: An apparatus including a single electrolytic/reaction cell, for extraction of titanium sponge from rutile ore. Magnesium chloride is electrolytically separated into magnesium metal and chlorine gas within the cell. The chlorine gas produced is reacted with rutile ore and coke to produce titanium tetrachloride in a separate chlorinator and the product is directed to the cell subsequent to completion of electrolysis. Titanium tetrachloride is reacted with magnesium metal in the same cell where the magnesium is produced to form titanium sponge and magnesium chloride. The titanium sponge is separated within said cell with the magnesium chloride being recovered and recycled. Major impurities are separated by distillation. Plural electrolytic cells can be coupled to a single chlorinator in a continuous process. Very pure titanium sponge is produced with this self-replenishing process.

Abstract: A ventilator hatch assembly for vehicles, watercraft and the like, which is characterized by having a hatch member, which is interconnected to a mounting frame restable within a ventilation hatch opening for pivotal movements between alternative open ventilating and closed, latched, non-ventilating positions. The hatch cover and mounting frame are interconnected by separable hinge means and separable flip-action or snap-action latch means which operably cooperate to accommodate rapid opening and closing movements of the hatch cover and also to facilitate complete and rapid removal of the hatch cover from the hatch opening to permit the latter to serve as an emergency exit from the vehicle or craft.
