Abstract: ABSTRACT OF THE DISCLOSURE A Cr (V1) ions-containing chlorate cell liquid containing an alkali metal chlorate and an alkali metal chloride produced in electrolysis step is acidified to a pH 1 to 5,  and then passed through an anion exchange resin bed, by which most of thc Cr (VI) ions are separated.  Then an aqueous alkali metal chloride and/or alkali metal chlorate solution containing a barium salt soluble in water is added to the effluent to precipitate barium chromate.  The pre-cipitate is filtered and a substantially Cr (VI) ion free chlorate cell liquor is obtained.  The filtered precipitate of barium chromate is dissolved in an aqueous hydrochloric acid solution, which is, then, passed through a cation ex-change resin bed which adsorbs only barium ions and an aqueous hydrochloric acid solution containing Cr (VI) ions is obtained.  The anion exchange resin bed which has  absorbed Cr (VI) ions is regenerated more efficiently with an eluent containing an aqueous alkali metal hydroxide, an alkali metal chloride and an alkali metalchlorate.  The aqueous hydrochloric acid solution passed through the cation exchange resin bed and the aqueous alkali metal hydroxide solution from thc regeneration state of the anion exchange resin bed are mixed and returned to the electrolysis step.  The cation exchange resin bed which adsorbs the barium ions is regen-erated and the barium ions are refused for precipitating barium chromate.

Abstract: COAL GASIFICATION POWER GENERATION PLANT     Abstract of the Disclosure A combined cycle coal gasification power plant includes a coal gasifier which generates low BTU coal gas for consumption by a gas turbine.  Before being applied to the gas turbine, the coal gas is passed through a clean-up system which removes undesirable constituents from the coal gas.  Efficient operation of the clean-up systme requires that a predetermined discharge pressure of clean coal gas leaving the clean-up system must be maintained.  A control system controls the coal gasifier according to either one of the discharge pressure of clean coal gas and the turbine power output requirement while maintaining the clean coal gas discharge pressure and power output at predetermined values.

Abstract: PARISON HANDLING ASSEMBLIES & METHODS FOR HANDLING PARISONS                 ABSTRACT OF THE DISCLOSURE     A parison handling assembly receives tubular plastic parisons from a random bulk storage, orients the parisons, and feeds the parisons in a controlled manner to one or more blow molding machines. Parisons are stored in the random bulk storage and fed at a controlled rate by a metering apparatus to a parison orienter which orients the parisons into a closely grouped arrangement wherein the parisons are both upright and side-by-side, The parisons are fed from the parison orienter to a parison escapement mechanism which holds the parisons temporarily. The escapement mechanism is actuated to release parisons into a parison transporter depending on the production demands of the individual blow-molding machines. Released parisons, from the parison escapement mechanism, move along the parison transporter to be pushed axially into stuffer tubes. The stuffer tubes hold the parisons in properly oriented, end-to-end relationship for delivery to the actual loading station of the blow-molding machine.

Abstract: ABSTRACT        Glucose-containing products can be manufactured in apparatus comprising a continuous screw conveyor member-rotatable in a continuous press cylinder having three regions in cascade arrangement between an intake opening and an output opening.  The regions comprise an intake region for the rapid and economical intake of different kinds of products, a compression region for building up a very high pressure of from about 20 to 300 bars for disintegrating the products and for heating the product by intensive shearing thereof to a temperature of up to 250°C, and a catalyst injection region for intensive action on and mixing or hydrolysis of the cellulosic substances with trifluoroacetic acid or the like injected through nozzles.  Thus glucose-containing products can he hydro-lysed by the action of trifluoroacetic acid, in apparatus in which all the working steps to be carried out can be performed continuously, without having to use individual pieces of equipment such as soaking containers, boilers, refiners and corresponding connecting ducts and valves.

Abstract: ABSTRACT OF THE DISCLOSURE       A twin wire former of a paper making machine in which one of the wires is supported on a surface of each of a number of forming shoes longitudinally spaced along the extent of the wires.  Each forming shoe has a number of longitudinally spaced grooves in the surface contacted by the one wire, each of the grooves extending in a direction at an angle to the longitudinal direction less than 90°, such that scraping pressure applied to the raw material liquid guided between the two wires, by the surface between the grooves is released into the grooves.  This arrangement of grooves creates a pressure difference in the raw paper material liquid in a direction transverse to the longi-tudinal direction of the wires to produce a transverse flow of the raw paper material liquid, thereby reducing the machine-direction to cross-machine-direction ratio of the fibers of the paper being formed.

Abstract: ABSTRACT A hydrodynamic power transmitting construction, such as a clutch, has a pump-wheel connected with the axle of a driving machine, a turbine-wheel connected with the axle of a working machine and a closed working space for these and the working liquid.  An axle sleeve fixed to the turbine-wheel is carried in bearings provided with protecting packing.  The space between the working space and the packing is connected to an - atmospheric or other -buffer space, the pressure of which in any working condition is less than or equal to the pressure causing a pressure decrease through the bearing.  Con-sidering the changes in the physical characteristics due to possible irregular temperatures during working the construction has at least one protection fitting, comprising a threaded pin arranged in a space communicating with atmospheric space and projecting into the vicinity of the rotation axis of the power transmission construction.  In this pin a well-known cracking disc is arranged, and operates to fracture, and relieve overpressure in the closed working space.
