A vehicle power steering control device including a reaction assembly which applies a reaction force on the steering wheel that depends on both steering effort and vehicle speed. The device comprises a vehicle speed responsive modulator valve for controlling or modulating a pressure of fluid from a fluid pump in response to a signal from a vehicle speed sensor. Since the pressure of fluid from the fluid pump is proportional to the steering effort on the power cylinder, the output pressure of the...

An electromechanical power train system for an automotive vehicle having a driving engine with a torque converter in which an electric-generating and motor means having operation as a generator and/or motor for generating electric energy for storage supply when driven by the engine and for driving a driven shaft when energized by the storage supply, is accommodated therewith together with an electronic controller for controlling the operation of the components with speed reduction gear. The driv...

The machine embodying the mechanism is of low silhouette frame construction so that it reduces the weight of the machine and the space required for its use. The means for operating the needle carrier is an oscillating arm which serves to shift the needle carrier back and forth along a straight line. One end of said arm is positioned in a slideway in said needle carrier so as to be free for both rotational and translational movement relative thereto. Provision has been made for adequate lubricati...

The invention pertains to a barrier which can be raised and lowered to permit only authorized parking within a given parking space. The barrier is pivotally mounted on a base plate which is fixed in the ground, and the barrier is in the form of a post having an internal locking member and a lift mechanism which is reinforced by the post against bending or other distortion. A lift handle is located transversely within the post and extends on either side for a sufficient distance so that conventio...

A carpet cleaning apparatus comprising a cylindrical brush rotating in contact with the floor and at least one brush reciprocatory in the direction of travel of the apparatus in contact with the floor and mechanically connected to the rotary brush, and a vacuum cleaner nozzle associated with said reciprocatory brush.

A hydrofoil system for water-craft consisting of a bow hydrofoil and a stern hydrofoil of a surface-piercing transversely stabilizing type is described which does not require adjustment or trimming means when the craft is running. Each hydrofoil is approximately V-formed in both front and top views such that the pointed ends of the two V-forms face away from each other, pointing downward ahead and downward astern, respectively.

A solid electrolytic capacitor including a first electrode having formed an oxide film on its outer surface, a second electrode disposed opposite to the first electrode and a solid electrolyte composed substantially of granular manganese dioxide of gamma type and disposed in contact and between the first and second electrodes. The solid electrolyte has a high film-forming ability and is prepared by electrolyzing manganese sulfate dissolved in an aqueous solution of sulfuric acid. The solid elect...

The illustrated embodiments include an exciting generator and a power generator. Each of the generators includes a common tubular rotor. The armature of the exciting generator is maintained within the rotor and is fed through a control rectifier to the field of the power generator, which is also maintained within the rotor. The output voltage of the power generator is sampled for modulation of a radio transmitter which delivers power to a transmitting antenna. A receiving means maintained within...

A hay bale vehicle is described having the capability of picking up hay bales from a field one at a time and stacking the hay bales on a bed. The vehicle further has the capability of unloading the stacked hay bales as a stack or unstacking the hay bales and discharging the bales one at a time from the vehicle.
