Abstract: ABSTRACT OF THE DISCLOSURE       The present specification discloses a method of selective dissolution of the non-ferrous metals such as copper, lead and zinc contained in pyritic ores.  The method invention is applicable especially to ores of solid pyrites which contain non-ferrous metals in the form of sulphides or of very finely crystallized sulpho-antimonides and sulpho-arsenides.  Such ores are characterised by fine crystals, which may be of the order of a few microns in size, and by the distribution of copper, lead and zinc ores in the pyrites,the matrix generally being of small volume.  The method according to the-invention can also be successfully applied in the treatment of other ores, for example cupriferous pyrites containing only a certain proportion of copper sulphide, or more complex pyritic ores containing in addition lead sulphide and zinc sulphide, which may or may not be associated with copper sulphides, or sulphurized concentrates obtained by flotation, such as blende, galenite or chalcopyrite.          The method for selectively dissolving non-ferrous metals contain-ed in pyritic ores, comprises crushing the ore, introducing the crushed ore, which being stirred and at a temperature above the ambiant temperature, into a reaction vessel containing a solution of chlorides of a metal having two valency states, and injecting gaseous chlorine into said reaction vessel.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention is directed to a photocompo-sing machine and method in which characters of several differ-ent type styles are arranged in concentric rows on a continu-ously spinning character matrix disc.  The disc is mounted on a carriage which is movable relative to a stationary photo-graphic film sheet, and a carriage supporting several projec-tion lenses is releasably secured to the disc carriage.  A flash lamp also is secured to the disc carriage in a position to flash light through the disc, through one of the lenses, and onto a sheet of photographic film which is located very near the lenses.  Characters are composed in lines on the film by first locking the lens and disc carriages together, and mov-ing the combination of those elements and the flash lamp, as a unit, across the film while selectively flashing the lamp to project character images onto the film.  Each of the lenses magnifies the image it receives by a different factor and thus produces characters of a different size on the film.  The lenses are arranged in a linear array in a holder releasably secured to the lens carriage.  The lenses are relatively small and in-expensive and the optical system is simple and compact because the focal lengths and apertures of the lenses are small.          Furthermore, all of the character images are transmitted pri-marily through the lenses in the direction of the axis so as to maintain high quality images and type composition.  The lenses and mounting means are relatively lightweight and thus can be moved relatively easily in order to maintain the opera-ting speed of the machine at a high level.

Abstract: DIGITAL REPETITION RATE CHECK CIRCUIT                 ABSTRACT OF THE DISCLOSURE         A pulse repetition rate check circuit of the type which detects when the second of two consecutive pulses from a pulse generator is early or late with respect to a predeter-mined repetition time period.  It includes an early pulse detec-tor, first and second early pulse detector enabling circuits and first and second clocks.  Each early pulse detector enabling cir-cuit enables the early pulse detector responsive to its associ-ated clock for a predetermined time so that a second pulse occurring within the predetermined time is detected as an early second pulse.  The early pulse detector enabling circuit includes an inhibit arrangement for preventing the enabling of the early pulse detector after it has been once enabled.  A steering circuit alternately directs the clocking signals from an oscillator to the clocks responsive to alternate pulses and a clock reset ar-rangement associated with each clock causes each clock to be re-set responsive to the other clock to assure that one clock is always conditioned to act upon the receipt of the next pulse.          The pulse repetition rate check circuit also includes first and second late pulse detectors which are coupled to the first and second clocks respectively for providing an error signal indicating that the second pulse is late should the second pulse fail to occur within the predetermined repetition time period.

Abstract: NOZZLE SEAL     A B S T R A C T     In an illustrative embodiment of the invention, a nuclear reactor pressure vessel, having an internal hoop from which the heated coolant emerges from the reactor core and passes through to the reactor outlet nozzles, is pro-vided with annular sealing members operatively disposed between the outlet nozzle and the hoop and partly within a retaining annulus formed in the hoop.  The sealing members are biased against the pressure vessel and the hoop and one of the sealing members is provided with a piston type pres-sure ring sealing member which effectively closes the path between the inlet and outlet coolants in the region about the outlet nozzle establishing a leak-proof condition. Furthermore, the flexible responsiveness of the seal assures that the seal will not structurally couple the hoop to the pressure vessel.

Abstract: ABSTRACT OF THE DISCLOSURE     This invention relates to a female electrical contact for use as an electrical connector or as one contact of a multi-contact electrical connector.  Prior art female contacts are generally configured in a U-shape with the arms of the U extending in a direction axially of the contact and bent toward one another for receiving a mating male contact pin.  Occasion-ally, the male contact pin may be incorrectly inserted so as to push one of the contact leaves away from the axis of the contact, and give rise to a faulty contact.  If the elastic limit thereof is exceeded, the contact becomes useless.  According to the invention, there is provided a single-piece female electrical contact formed from a single piece of sheet metal and which includes a pair of opposed contact leaves enclosed in the end of a tubular member of rectangular cross section.  The tubular member has a closed end with a small aperture at its center opening into between the two opposing contact leaves.  The base for the contact leaves is U-shaped and has a pair of tabs which are bent to retain one of the rectangular faces of the tubular member in firm fixed position.  The closed end may be concave to provide a camming action for the male pin to be inserted in the aperture therein.  Additionally, a terminal strip portion can be provided extending from the U-shaped face to provide connection for an external conductor.
