Abstract: ABSTRACT     ARRANGEMENT OF BUSBARS FOR ELECTROLYTIC REDUCTION CELLS            An arrangement of busbars leads the direct electric current from a transverse electrolytic cell (10) - in particular such a cell for producing aluminium - to the anode beam (38) of the next cell (12).     The self consistent magnetic field of the cell (10) is almost completely compensated if, at the upstream cathode bar ends (16), at least two individual or groups of cathode busbars (18) and connecting busbars (20, 22) lead to a busbar (28,42) connected to the downstream cathode bar ends (30) or to a riser (36, 40).     A part of the connecting busbar (20) runs completely under the cell at the middle; the other part likewise runs under the cell until it is in the region of the longitudinal axis (L) where it follows this axis until it projects out beyond the end wall (24) of the cell (10), and finally runs along the cell.

Abstract: INVENTORS:  IMRE BAJKA and ROBERT FURRER            INVENTION: APPARATUS FOR APPLYING SOLDER TO A PRINTED-CIRCUIT             BOARD     ABSTRACT OF THE DISCLOSURE             The solder applying apparatus enables applying solder to both sides or faces of printed-circuit boards travelling essentially in horizontal direction through a production or manufacturing line, and which circuit boards are not yet equipped with electrical components or the like.  The apparatus contains a solder applicator means or device where liquid solder is pumped from a supply container in such a quantity that a solder wave forms over an outlet or discharge opening of the applicator device.  This solder wave extends beyond the feed or transport plane of the printed-circuit boards.  At the side walls of the applicator solder device there are mounted guide elements formed of metal plating or sheet metal which extend beneath the feed plane, the solder flowing-off by means of such guide elements.  The angle of inclination of the metal guide elements is adjustable with respect to the feed plane.  Also the spacing between the discharge opening of the applicator solder device and the feed plane is variable.  Directly above or below, as the case may be,  the  feed  plane  there  are  arranged  substantially cylindrical-shaped elements at the inlet side and the outlet side where the printed-circuit boards respectively inbound and outbound  from  the  solder  applying  apparatus.   These cylindrical-shaped elements are disposed at the regions of the ends of the guide elements and extend transversely with respect to the direction of feed or advance of the printed-circuit boards.  These cylindrical-shaped elements function, on the one hand, as solder strippers or scrapers and, on the other hand, as limiting means for the solder blanket which during the through-passage of a printed-circuit board tends to spread-out at the upper surface or face thereof.

Abstract: ABSTRACT          A hand knife 20, 120, 220 of the type having a ring-like rotary driven blade 26, useful for cutting meat and the like; a blade housing 24, 124, 224 for a hand knife; and an improved circular blade 26.  The blade housing has a generally circular groove 38, 138, 238 in one axial end 40, 140, 240 of the housing.  The groove is as wide at the open end as inwardly to allow the blade to be inserted and removed in an axial direction.  The housing receives and fully encloses a ring gear portion 56 of the blade while a cutting portion 60 extends from the groove.  A blade re-tainer 28, 228 secured to the handle acts against a radial flange 62 of the blade when tightened, to retain the blade within the groove, and when loosened allows removal of the blade from the housing without removing or loosening the housing from the handle.     *

Abstract: Abstract A catalyst for use in the production of linear low density polyethylene is prepared by contacting a silica carrier with an organomagnesium compound in a carrier liquid so that magnesium is transferred onto the carrier by precipitation and reaction with surface hydroxyl sites on the carrier.  The resultant solid supported magnesium compound is then treated with a tetravalent titanium compound in a carrier liquid.         On activation, the catalyst is found to be effective in producing linear low density polyethylene having a density of 0.930 and below by polymerization of ethylene with hexene in the gas phase.

Abstract: APPARATUS AND METHOD FOR REDUCING       CHANNEL POWER LOADING Abstract of the Disclosure A conventional telephone system including terminal equipments interconnected by a communications channel typically employs a supervisory tone transmitted by each terminal equipment to indicate its idle condition. When the friction of idle terminal equipments is high, the total energy carried over the channel is determined substantially by these tones.  The apparatus of the type disclosed herein, employed in association with each terminal equipment, effects a reduction in the channel power loading due to those tones.  The apparatus includes circuit means for generating a control signal during the presence of the idle state supervisory tone being transmitted from or received by the associated terminal. Other circuit means respond to the control signal to cause the supervisory signal transmitted by the terminal into the channel to be attenuated by a fixed power ratio and to cause the supervisory signal received by the terminal from the channel to be amplified by the same fixed power ratio.

Abstract: ABSTRACT OF THE DISCLOSURE           A process for separately recovering zinc and lead values from zinc and lead containing sulphidic ore which also contains iron comprises subjecting ground ore to a first flotation step to float an initial lead concentrate containing zinc and produce zinc and iron containing tailings.  The zinc and iron containing tailings are subjected to a second flotation step to float an initial zinc concentrate containing iron and also produce tailings.  The initial zinc concentrate is subjected to a third flotation step to float a further zinc concentrate containing iron and also pro-duce zinc and iron containing tailings.  The zinc and iron containing tailings from the third flotation step and at least a lead and zinc containing portion of the initial lead concentrate are leached in a first leach step under oxidizing conditions at a temperature in the range of from about 130 to about 170°C in aqueous sulphuric acid solution with a stoichiometric excess of sulphuric acid relative to the zinc content of from about 50 to about 150% so as to give a terminal acidity of from about 50 to about 80 g/L to produce a lead-containing residue and a first leach solution containing zinc and iron.  The lead con-taining residue is separated from the first leach solu-tion and the first leach solution is treated with the further zinc concentrate or calcine produced therefrom by roasting to dissolve zinc therefrom and precipitate a substantial amount of dissolved iron, thereby pro-ducing an iron containing residue and a second leach solution containing zinc.  The iron containing residue is separated from the second leach solution, and the second leach solution is treated to recover zinc.

Abstract: ABSTRACT          An improved seal assembly is shown for use in an oil well packer of the type having a packer body having a longitudinal bore, a packer carried on the body for sealing off the annular space between the body and a surrounding well conduit, a mandrel slidably disposed within the body longitudinal bore, the mandrel being spaced-apart from the body to define a fluid flow path between the mandrel exterior and the interior of the body, and wherein the mandrel is slidable between an open, running-in position in which the fluid flow path communicates the annular space above the packer with the mandrel longitudinal passage-way and a closed, set-position in which the fluid flow path is sealed off.  The improvement comprises a face seal housing as a part of the mandrel which has a weight loading shoulder and a deformable seal portion. The weight loading shoulder is engageable with the packer body when the mandrel is in the closed, set-position to thereby support the weight of the mandrel from the body.  A pressure biased seal compressor is carried between the mandrel and the body for contacting the deformable seal portion when the mandrel is in the closed, set-position to seal off the fluid flow path.          The weight loading shoulder supports the large compressive loads often encountered in service work without increasing the compressive stress on the deformable seal.
