Abstract: ABSTRACT      A filtration apparatus for removing undesirable components from a solution to be treated, comprising a module in which a number of hollow fibers fixed at one end thereof by cast-molding materials, opened at the end portion above described and closed at another end portion thereof, in which said solution to be treated can definitely be kept from leaking out of a mechani-cally sealed portion.  Also, any defect in said sealed portion can be detected from the outside by leading the leaked solution to the outside of the apparatus even if the defects were in said mechanically sealed portion.         This apparatus is preferably used for the manufacture of purified water free from bacteria, pyrogene and the like.  Ultra-purified water of remarkably high purity can be obtained when it is used as a check filter in a process for manufacturing ultra-purified water.

Abstract: Abstract of the Disclosure Pressure Transducer Assembly A pressure transducer assembly is disclosed for directly monitoring pressure in a fluid which flows through the assembly. The assembly includes a housing defining a chamber therewithin and having an inlet port and an outlet port in fluid-flow communication with the chamber. An electrically insulated body element is sealed within the chamber dividing the chamber into a first chamber and a second chamber. The first chamber is in fluid-flow communication with the inlet and outlet ports. The second chamber is separated from the first chamber by a fluid-tight seal such that any fluid present in the first chamber cannot enter the second chamber. A pressure transducer sensor is secured in the insulated body and exposed to the first chamber such that the sensor can determine the pressure in a fluid in the first chamber and convert the pressure into electric impulses. The sensor is separated from the fluid in the first chamber by an insulating medium across which fluid pressure can be determined. Connected to the sensor are electrical conductors which extend through the insulated body and into the second chamber. The second chamber provides an engagement site for an electrical connector which can interconnect with the electrical conductors and provide an electrical path through which the electric impulses generated by the sensor can be transferred to a monitor.

Abstract: ABSTRACT OF THE DISCLOSURE In a color printer in which a shuttle assembly con-taining a plurality of impacting print hammers is reciprocated in bidirectional fashion relative to an opposing platen to impact a print paper against the platen through the different color zones of an ink ribbon to print in color, the different color zones of the ribbon are arranged in a repeating pattern along the length thereof enabling the lightest color to be printed first followed by successively darker colors as the ribbon is advanced bidirectionally between the opposite ends thereof.  A pair of barrier zones having a blank ribbon zone therebetween are disposed between each adjacent pair of color zones on the ribbon to prevent ribbon contamination due to bleeding of ink between adjacent color zones when the ribbon is wound on a reel. Ribbon contamination is further prevented by the blank ribbon zones which absorb ink that rubs off onto the ribbon guides.  The various different color zones are identified by one or more strips which extend across the width of the ribbon adjacent each color zone and which identify the color therein in bar code fashion.  The color printer may be operated in a manner which provides multiple passes of each color zone through the print station between the shuttle assembly and the platen to prolong the life of the ribbon and to enable the printer to quickly advance to the next color zone with a minimum amount of search time.  The print paper which is driven bidirectionally by tractor drives above the print station is held in tension by an arrangement below the print station which employs a torque motor having an elasto-meric wheel engaging a side of the paper opposite an arrangement of non-ink absorbing rollers.

Abstract: ABSTRACT OF THE DISCLOSURE          The removal of radium from acid-leached uranium mill tailings has been difficult due to its strong retention as mixed sulfates and in adsorbed forms.  With this invention the leaching action of a complexing agent (reducing the free radium cation concentration in solution) is combined with that of a reducing agent.  Thus, high valency metal hydroxides and basic salts (notably Fe3+) which tend to retain radium are converted to the lower valency form which is much more soluble in the complexing agent.  The reducing agent employed is sodium hydrosulfite, in combination with various organic complexing agents;  the preferred complexing agent is EDTA.  Over 90% of the radium in uranium leach tailings from Elliot Lake can be removed in 1 hour contact at room temperature with a solution comprising 0.04M of both sodium hydrosulfite and EDTA, with 1.0M potassium chloride added as a surface charge depressant.  The gradual addition of the solids to liquid permits the use of low liquid/solid ratios.
