Abstract: Title:       "Redundant Control Actuation System - Concentric Direct Drive Valve"     ABSTRACT OF THE DISCLOSURE A redundant control actuation system for an aircraft including an electro-mechanically controlled, hydraulically powered actuator for driving a main control valve of a servo-actuator control system. The actuator includes a tandem piston connected to the main control valve and a force motor driven tandem pilot valve axially movable in the piston for simultaneously controlling the differential application of fluid pressure from respective hydraulic systems on opposed pressure surfaces of respective piston sections to cause movement of the piston in response to relative axial movement of the pilot valve as long as at least one hydraulic system remains operative. The piston pressure surfaces are sized and arranged to minimize force unbalance on the piston due to pressure variations in the hydraulic systems. Also, a pilot valve centering spring device may be provided to minimize undesirable transient motions during system turn on and shut down. Upon failure or shut down of both hydraulic systems, a shut off valve sleeve concentric with the pilot valve moves axially in the piston to render the pilot valve inoperative and release fluid pressure from opposed, corresponding pressure surfaces of the piston sections to respective returns therefor through centering rate control orifices as the piston is moved to a neutral position by a centering spring device acting on the main control valve.

Abstract: ABSTRACT A sieve machine, consists of a sieve box and a sieve mesh that is directly movable by means of bumpers distributed over its surface, and mounted on striker bars that are arranged beneath the sieve mesh.  The striker bars project from rods oriented transversely to the direction of movement of the material to be sieved and installed so as to be fixed in a frame.  The striker arms have pivot levers that are caused to oscillate through the medium of a common push rod driven by a vibrator.  In order to provide for an even better match between the sieve machine and the sieve behaviour of the material to be sieved, which also provides for simpler production, a)  the rods are mounted at their ends by means of elongated metal-lic plate springs (101) that are oriented along the length of the sieve mesh (2) and are arranged at least approximately  at the same level as the mesh, the plate springs being secured at one end on the sieve box and on the other to a rod (4); and b)  an electromagnetic vibrator (10) acting exclusively linearly and permitting adjustment by frequency and/or amplitude is used as a vibrator.

Abstract: Abstract of the Disclosure A small flip-top container which can be opened and shut using one hand is closed at one end by a stopper having a skirt which grips the inside of the container resiliently and a rectangular end wall with an aperture which extends for a certain distance from one of the minor sides.  The aperture is closeable by a flap which is hinged integrally to the end wall at the inner end of the aperture and is held shut by the snap-engagement of a transverse heel formed on a projection from the free end of the internal surface of the flap in a complementary transverse groove from in the minor wall of the skirt immediately below the outer end of the aperture.  In order that the flap can be snapped open and shut without excessive force, the frontal edge of the minor wall of the skirt defining the top of the groove has a central part which projects outwardly relative to its lateral parts, over which the heel must pass.  For strength, the internal surface of the flap has two lateral ribs which extend for about a third of its length from its free end.

Abstract: A STEERING SYSTEM AND COMPENSATING VALVE        Abstract of the Disclosure A hydrostatic power steering control system with variable feedback compensation employing a unique compensating valve. The steering control system includes first and second hydraulic cylinders, each having two internal chambers denoted as head and feedback chambers.  A piston is movably retained in each of the cylinders and is attached to a piston rod which extends outwards.  The pair of piston rods are connected to a pair of steerable wheels by a mechanical linkage.  Fluid contained in a reservoir is pressurized by a supply pump and is selectively passed to a head chamber of one of the cylinders by a control valve.  The control valve is actuated by pressure differences in two interconnected fluid passages which connect to the feedback chambers of the two cylinders.  A pressure difference in these passages is created by manually operating a steering wheel which actuates a metering pump positioned across the fluid passages. In order to alleviate pressure fluctuations between the two feedback chambers, a compensating valve and a pair of one-way check valves are connected across the fluid passages in a parallel relationship.  The compensating valve allows pressurized fluid above a predetermined pressure range value to be relieved from the system, but does not limit a pressure value generated by the metering pump.
