Abstract: A vehicular power steering system is provided with a steering effort control system which controls the degree of power assistance by controlling the supply of hydraulic fluid to the hydraulic power actuator unit. The steering effort control system monitors the speed of the vehicle and the angular velocity of the steering wheel, and controls the quantity of the fluid supply in accordance with the monitored variables. The fluid supply quantity is determined so as to satisfy the following three conditions: (1) The steering must become heavier as the vehicle speed increases; (2) however, a sufficient amount of the fluid must be supplied even when the steering wheel is turned rapidly; and (3) the driver must be given a feel about the lateral acceleration of the vehicle during a turn.

Abstract: A process for treating wash water from the manufacture of terephthalic acid, wherein the wash water includes terephthalic acid, metal catalyst, and organic acid byproducts. The process includes the steps of passing the wash water through a filter medium to remove undissolved terephthalic acid solids, passing the filtered water through a cation exchange resin in hydrogen ion form to remove the metal catalysts, and passing the water through an anion exchange resin to remove dissolved terephthalic acid and dissolved organic acid byproducts. The treated water and certain components removed from the wash water are recovered and reused in the manufacture of additional terephthalic acid. An apparatus in which the process is practiced is also described and, after a quantity of wash water has been treated, the apparatus is regenerated with regenerants that are also recovered and reused in the manufacture of additional terephthalic acid.

Abstract: A swing arm suspension for automotive vehicle has a suspension arm pivotably connected to a suspension member for rotation about a substantially horizontal pivot axis. A lateral rod is connected to the suspension arm at one end thereof via a bushing and to a suspension member at the other end via another bushing. The position where the lateral rod is connected to the suspension member and to the vehicle body are offset from the pivot axis of the suspension arm. The position is chosen such that the lateral rod serves to provide roll compensating force for the suspension to satisfactorily and successfully restrict roll or compliance steering effects in the toe-out direction and to prevent positive camber. The lateral rod is adapted to be connected to the suspension member at such a position as to cause toe-in and/or negative camber.

Abstract: An oscillating displacement pump particularly adapted for pumping a viscous and abrasive fluid medium or one loaded with solid particles. The pump includes a connecting space located outside of a displacement unit and directly connecting a suction valve space with a pressure valve space so that the geodetic height of pumped medium increases. The connecting space defines a suction valve side connecting channel and a pressure valve side connecting channel connected at any given time with each other through the displacement unit space independent of the position of the displacement unit. The pumped medium can thus be moved through the pump from the suction valve to the pressure valve without diversion in a separate connecting space reducing abrasive wear on the pump.
