Abstract: ABSTRACT OF THE DISCLOSURE    A process of producing a potassium sulfate salt comprising reacting sulfuric acid with potassium chloride at an equivalent ratio of sulfuric acid to potassium chloride of 1.07 to 1.40 at a temperature of from the melting point of potassium bisulfate to about 500°C while allowing the resulting solid-liquid mixture at the final reaction stage to be substantially in a state of wet cake, said potassium bisulfate being present in the reaction system until the termination of the reaction because of the excess sulfuric acid.   In such a process, the reaction proceeds smoothly at a relatively low temperature and is completed in an extremely shortened period of time to produce a potassium sulfate salt with an extremely low chlorine content which is useful as a raw material for the production of potassium-containing chemical manures to be suitably applied onto the farmland of tobacco etc. which are apt to have their growth hampered by chlorine values.  In the present process, when the reaction mixture is kneaded, the rate of reaction is extremely accelerated, and as a result, the reaction period of time needed for lowering the chlorine content of the product to a limited level is markedly shortened.

Abstract: ABSTRACT OF THE DISCLOSURE      The disclosed apparatus for extracting mean of small crustaceans comprises a mechanism for breaking up the shell of the crustaceans including a diffuser, and a mechanism for separating the meat from other components of the crustaceans. The separating mechanism includes a vertical vessel filled with a working fluid, communicating with a chamber for feeding the mixture of the  meat with other components of the crustaceans, a line for removing the meat of the crustaceans and means for removing the rest of the components. The upper zone of the ver-tical vessel flares upwardly. The conduit connecting the mix-ture feed chamber with the vertical vessel is preferably loca-ted in the latter's upper zone. Preferably, a working fluid supply conduit is arranged at the central zone of the vessel. The lower zone of the latter, narrows downwardly and is con-nected with the meat removal line incorporating liquid-type ejector. The outlet end of the line is situated above the top leve of the working fluid in the vertial vessel. The mixture feed chamber has in the upper portion thereof a device for feeding the working fluid, with the diffuser underlying this device above the top level of the working fluid. The apparatus enables to obtain the meat of small crustaceans in the form of an integral lump of the muscular tissue, devoid of the shell, liver, lipids gastrointenstinals tract and other com-ponents. The apparatus offers the simple and economically efficient technology of processing antarctic krill directly in the fishing ares, to obtain the unconventional kind of food.

Abstract: Abstract:       Aqueous, colloidal dispersions of fluorinated polymers can be concentrated, after adding a stabilizing emulsifier, to high solids contents by ultrafiltration over customary semi-permeable membranes if pulps which keep the dispersion free from contact with components which cause frictional forces are used for conveying the dispersio       A considerable proportion of the stabilizing emulsifier added and high proportions of the fluorine-containing emulsifier originally contained in the fluorinated polymer dispersion from the emulsion polymerization can be removed via the aqueous permeate. The fluorine-containing emulsifier can be recovered by a downstream basic anion exchanger and the stabilizing emulsifier contained in the filtrate flowing out of the anion exchanger can be concentrated in this filtrate by reverse osmosis and optionally recycled into the ultra-filtration process.     Fluorinated polymer dispersions which, in addition to having a high solids content, are distinguished by particularly low contents of fluorine-containing emulsifier and of stabilizing emulsifier can be obtained.     The process can be applied to all known aqueous, colloidal dispersions of fluorinated homopolymers and copolymers.

Abstract: Abstract of the Disclosure A truck for wheeled vehicles, particularly intended for rapid transit railway vehicles, consists of two parallel side frame members connected together by a transom that is rigidly fixed to one side frame and pivoted to the other side frame about a horizontal axis, so that the two frames can swivel pitch to reduce wheel unloading as much as possible.  Preferably the swivel has the characteristic of a ball joint to permit yaw and tilt between the two side frames, such a bearing comprising for example, a tube of resilient material between a  pin and cylinder. The primary suspension between the wheels and axle units and the frame members may be by resilient pads, while the secondary suspension of the vehicle body is on the frame by vertical springs on the side frame members.  The transom is connected to the vehicle body by a bearing that permits pivoting while carrying the traction load.  There is no bolster or centre plate and the transom does not carry the car body weight.  Preferably the adjacent ends of the two frame members are connected by rigid rods that are connected at their ends to the frame members by ball joints so as to maintain the frame members parallel.

Abstract: ABSTRACT A rod guide for a suspension strut has a bearing sleeve, outer sleeve and a resilient elastomeric sleeve bonded therebetween.  The outer sleeve is fixed to the top portion of the strut body.  The bearing sleeve has an aperture therethrough sized to slidably receive the piston rod of the strut such that side loads exerted on the body and piston rod of the strut flexes the elastomeric sleeve to maintain alignment of the bearing sleeve with respect to the piston rod extending therethrough.  This structure decreases static friction occurring between a sliding piston rod and the rod guide fixed to the strut cylinder.

Abstract: HIGH PRESSURE FEEDER PIVOTAL CENTER SCREEN            ABSTRACT OF THE DISCLOSURE          A high pressure transfer device and a method of continuously conveying a liquid suspension of particulate material utilizing the transfer device are provided.  The device includes a pocketed rotor rotatable in a housing, with a center screen mounted in each rotor.  The screen is mounted within each pocket interior so that as liquid under pressure enters the pocket through its inlet the screen will move to enlarge the volume between the inlet and the screen.  This is accomplished by forming each screen as two screen portions and mounting the screen portions for pivotal movement with respect to a center post extending in the pocket coextensive with the rotor axis of rotation. Stops are provided extending from the pocket walls to prevent the screen portions for pivoting into alignment with the pocket inlet or outlet, and each pocket preferably has a substantially circular cross-sectional internal configuration.  The rotor portions are constructed so that they may be machined, allowing accurate and relatively inexpensive construction thereof.

Abstract: BATTERY FEED CIRCUIT            Abstract of the Disclosure The battery feed circuit provides a balanced dc feed current to a 2-wire telecommunications path.  The dc current in each conductor is generated by a bidirectional current source which is responsive to one of a complementary pair of first control signals along with a second control signal.  The complementary pair of first control signals is generated by a feed-back circuit which monitors the differential mode voltage across the path.  To reduce power consumption, the complementary pair of first control signals is a nonlinear function of the differential mode voltage. The resulting battery feed profile reduces the current on short path lengths.  Longitudinal balance is provided by the second control signal which varies the currents generated by each bidirectional current source by equal amounts.  This second control signal is generated by a second feedback circuit which monitors the common mode voltage across the path.  The above described circuit can also provide a number of features, such as feed current reversal and shutdown required in many telecommunications applications.
