Abstract: A steering assembly or system for vehicles such as a car comprises a speed increasing gear for the turning movement of the car steering wheel located under the steering wheel, at least one flexible shaft having the inner end connected to the speed increasing gear mechanism, and a transmission mechanism connected between the outer end of the flexible shaft and the steered road wheels of the car for transforming and transmitting the turning or rotary movement to a swinging movement of the steered road wheels. In one embodiment, the transmission mechanism includes a speed reduction gear mechanism at the terminal output end of the flexible shaft.
Abstract: The present invention relates to a method for producing metal from metal oxides, especially iron from iron oxides by a pre-reduction as well as final reduction wherein the pre-reduced oxidic material as well as optional slag formers and optional recirculated gas are injected at the bottom through tuyeres or the like by means of a carrier gas, inert or reducing of a reactor resembling a shaft furnace filled with solid reducing agent during simultaneous supplying of energy, e.g. in the form of oxygen gas and hydrocarbon, the oxidic material being blown against a pillar of solid reducing agent at such a level that essentially all injected solid material is retained (e.g. by galling) on the lower end of the pillar to bring the oxidic material to instantaneous final reduction, melting and possible alloying of the reduced metal.
Abstract: A power assisted steering system for a vehicle including a steering wheel operatively connected to steered wheels comprising a housing, a nut-and-screw mechanism comprising a nut member and a screw member, an input shaft mounted in said housing, at least one flexible shaft connected at one end to the steering wheel and at its opposite end to said input shaft, intermeshing gear means carried by said input shaft and one of said members of said nut-and-screw mechanism, means operatively connecting the other member of said nut-and-screw mechanism to the steerable wheels, the members of said nut-and-screw mechanism being of a configuration to preclude rotation relative to one another whereby upon rotation of one of said members, the other member is actuated in a rectilinear direction to thereby effect movement of the steered wheels, hydraulic circuit means including a double-acting servo-cylinder and a control valve including a slide member for controlling flow of hydraulic medium to and from said servo-cylinder,
