Abstract: A proportional flow control valve comprises a directional control valve having a valve spool, a servo actuator or servo means for operating said directional control valve, and manual override means for operating the valve spool. The servo means comprises a movable ram or piston for moving the valve spool to thereby operate the directional control valve and the ram has a pair of equally sized piston areas connected thereto. The servo actuator also comprises a pilot valve having a null position and is selectively operable to apply fluid alternately to either of said piston areas to effect ram and valve spool movement in one direction or another from a null position. Means including a proportional electromagnetic device such as a proportional solenoid or force motor are provided for selectively operating the pilot valve. Feedback means are connected between the ram and the pilot valve to maintain the ram and the valve spool in a position wherein they are moved. Orifice means are connected between the pilot valve and the piston areas for relieving fluid pressure on one piston area when fluid pressure is being applied to the other piston area. The orifice means also serve to relieve the fluid pressure on both piston areas whenever the signal to the proportional solenoid is zero and the pilot valve is in null position to thereby prevent ram movement. Biasing means are provided on the valve spool for maintaining the ram and the valve spool in null position whenever the proportional solenoid signal is zero. The biasing means exert a force on the valve spool which is less than the force exerted by fluid being applied to a ram area whenever an electric signal is applied to the proportional solenoid. The override means are manually operable to move the valve spool by means of a mechanical linkage to effect manual operation of the directional control valve.

Abstract: The invention is directed to a press having a crown member and a base member with support and tiedown means for maintaining the crown member at an operative predetermined work station relative to the base member, and operative press ram means operating between the crown and base means in direct or offset loading position on a workpiece, characterized in that the support and tiedown means comprises hollow columns characterized by greater resistance to the bending forces induced by offset loading than support and tiedown means comprised of solid columns composed of the same kind and amount of material as the hollow columns. These columns furthermore may comprise pressure fluid-actuated cylinders having cooperating pistons and piston rods. By rigidly affixing the base of these cylinders to one of the crown and base members and the free ends of the piston rods to the other, actuation of the piston rods to the outward throw or extended position moves the crown member away from the base member, and actuation to the inward throw or retracted position causes it to move toward the base member and, when so fully actuated, holds the crown member immovably at the predetermined work station. The hollow cylinders should optionally have a relative large length to breadth ratio and a relatively large bore.

Abstract: The invention relates to a method of recovering nickel from a spent fat hardening catalyst which consists of finely divided nickel metal on a carrier for example of infusorial earth and/or synthetic material and suspended in fat. The fat is saponified by means of an alkali solution to form a dissolved soap composition which is separated from the nickel metal and the carrier. The nickel metal is then leached out from the carrier and recovered in the form of nickel sulphate. Soap can be salted out of the dissolved soap composition and be used for cleaning purposes in industry, and the carrier can be washed and re-used. During the recovery waste solutions from the alkaline accumulator industry may appropriately be used so that only sulphuric acid is needed as a process chemical. The nickel sulphate solution recovered can be used, for example, as a raw material for the production of active nickel hydroxide mass for alkaline accumulators.

Abstract: For invention relates to a method of and a system for remote control of individual electronic equipments (R), which are spread out across a large geographical area. In particular it concerns activation of radio transmitters spread over the water surface and cooperating with hydrophones for taking up sound waves from submarines in order to localize these sub-marines. In order to achieve selective activation of the electronic equipments, electromagnetic waves or sound waves are transmitted with given relative time positions from at least three fixed stations (I, II, III) having known geographical positions. In each electronic equipment the waves are received and compared as regards their relative time positions at reception, activation of an equipment taking place only if a given criterion as regards said mutual time positions is fulfilled. Hereby activation of equipments will take place only within a given small zone of said large area. The position of said small zone is determined by the relative time positions of the transmitted waves, which can be varied in order to select different zones.
