Abstract: ABSTRACT OF THE DISCLOSURE           A device for conducting the electric current from the cathode of a hooded, transverse electrolytic cell to the anode of a neighbouring cell via cathodically polarised carbon blocks in the pot of a cell, cathode bars and individual conductor bars wherein the current from each cathode bar is passed under a cell to a compensating conductor bar which runs around the neighbouring cell.          This compensating conductor bar is connected to each anode of the cell it runs around via a flexible conductor strip; each anode is provided on its uppermost side with a yoke which is inserted and firmly secured in place, together with the conductor strip, in a notch or recess provided in a device for holding the anode in place, the anode holding device remains in place during anode changes and can be adjusted vertically by means of a motor or the like as a function of the voltage or the desired interpolar distance between anode and cathode.

Abstract: Docket No. P-5479 APPLICATION FOR LETTERS PATENT             OF NORMAN B. MOORE       FOR COMPOSITE HEAVY METAL DRILL COLLAR                  ABSTRACT OF THE DISCLOSURE        A composite drill collar for drilling bore holes in earth formations including a structural steel outer jacket having a lower end secured to a lower coupling connectable to a drill bit and an upper end secured to an upper coupling connec-table to an adjacent drill collar thereabove.  An annular heavy metal core of depleted uranium or sintered tungsten is disposed in the jacket and is held in compression therein as by shrink fitting it to the jacket.  The structural steel jacket has a heavy wall thickness to carry the bending, torsion, compression, tension and impact loads encountered in the drilling operation, so that such loads are not carried through the core, which has the purpose of increasing the density and mass of the composite drill collar, lessening considerably the tendency for a deviated well bore to be produced.

Abstract: Abstract of Disclosure A catheter assembly is described in which a catheter within a package can be extracted and utilized in a sterile manner which is particularly useful for a self-catheteriza-tion procedure.  As described with reference to one embodi-ment, the catheter assembly is formed with a bottom layer and a top layer between which the catheter is located in a sterile manner.  The top layer is provided with a backing so as to form a pocket in which one can place a hand and grip the catheter through the top layer.  Sterile packets of lubricating jelly and antiseptic wipe may be placed here.  The bottom and top layers are joined along a tear zone so that the layers can be separated from each other while gripping the catheter through the top layer and pulling the bottom layer away so that upon separation, one holds the catheter in a sterile manner.  In one form, the bottom layer is in the form of a bag to which one end of the catheter is connected so that the urine may drain into it.

Abstract: ABSTRACT OF THE INVENTION     The present invention is directed to an integrated circuit device comprising a lead frame having a ceramic capacitor mounted thereon and forming the support for a silicon chip bearing a multiplicity of circuits, including at least two power supply circuits namely a main power supply circuit and a secondary circuit.  The capacitor is shunted across the terminals of the main power supply and the main power terminals of said IC chip.  A conductive layer disposed atop the ceramic uppermost layer of the capacitor defines with the uppermost electrode of the capacitor, a second capacitive load of lesser value than the main capacitor, the said second capacitive load being shunted across the terminals of the secondary power supply and a secondary set of power terminals of said chip.  The provision of internal capacitive shunting for the plurality of power supplies for the chip enables lead length to the capacitors to be maintained at a minimum thereby minimizing inductive reactance and thus enabling small capacitances to effectively dampen noise and pulses in the circuit.

Abstract: REAR BAGGER ATTACHMENT FOR LAWN MOWER      Abstract of the Disclosure A bagger attachment for a tractor has a bag frame that includes a pair of upright brackets fixed to the rear end of the tractor which support, for vertical sliding action, a pair of plates fixed to respective bag rims.  There is provided, on the lawn mower, an upwardly and rearwardly projecting grass duct that has its upper discharge end positioned over the bag rims and which directs the grass clippings in a transverse direction.  Flexible bags are provided on each of the rims and depend therefrom.  A bagger lid receives the discharge end of the tube.  The lid is mounted on an axis that is substantially perpendicular to the portion of the duct that extends through the opening in the lid so that as the lid is raised, the duct will slide through the opening.  For discharging the bag, the rims may be raised to cause the horizontal plates to slide free of the vertical brackets.  The lid has, at its lower edge, a rib that snaps under the respective rims and tends to rigidify the bag assembly, as well as to hold down the lid.  The rib may be used to retain plastic liners that have their upper ends draped over the rims.
