Having Wedge Or Tapered Tightening Means Patents (Class 204/288.5)
  • Patent number: 8961751
    Abstract: A cell for direct treatment of liquid using electrolysis uses a modular construction of electrode plates and spacer assemblies positioned between end plates. Changes in the liquid flow capacity of the cell may be made by changing the number of module housing sections and electrode plate assemblies. The design includes electrode plates that lock into a mating module housing section to resist the pressure of the fluid being treated. The design further provides for multiple fluid flow paths and for automatic cleaning of the cell using standard clean-in-place methods.

  • Patent number: 7344625
    Abstract: The present invention relates to a handling device for an anode connector provided with at least two side trunnions and a tightening screw. The connector is generally capable of cooperating with attachment hooks of an aluminum production cell used in fused bath electrolysis production operations so as to enable connection of anodes onto the cell. The handling device has a tightening device capable of tightening the connector screw and affecting the tightness of the connector. The present invention also has a locking system that can lock the connector in a desired position in the handling device, by loosening the connector using the tightening device. The handling device also has at least one mobile member which typically has a support to support the connector in a closed position. The support can also displace the mobile member from its closed position to an open position, and vice versa.

  • Patent number: 7232507
    Abstract: An electrochemical cell design is disclosed for the particular application of the electrochemical treatment of contaminants in water. The cell is designed to allow the treatment of low concentrations of contaminants in low conductivity water efficiently, and to be simple to fabricate. The design incorporates tapered inlet and outlet fluid flow manifolds so that the cell pressure drop will be almost entirely due to fluid contacting the electrodes, thus maximising the effective use of the system pump power. A short anode to cathode distance and thin working electrodes are used to minimise resistive electrical power losses. The parallel slacked arrangement of the electrodes and the smooth inlet and outlet designs leads to relatively even distributions of current density and mass transfer resulting in maximal utilisation of the entire active electrode surface area.

  • Patent number: 6635159
    Abstract: The invention relates to a device for at least partly removing a deposit created in the electrolytic refining or electrowinning of metal from the surface of the mother plate used as an electrode in the refining or electrowinning process, said device comprising at least one member for removing the deposit and at least one member for controlling the removal member with respect to the deposit to be removed. According to the invention, the device comprises at least one gripping element that is used for creating a mechanical contact between the deposit and the removal member, said gripping element being connected to a control member, to which there are coupled both the shaft part of the gripping element and the deposit removal member.

  • Patent number: 6572760
    Abstract: Cathodic protection of a structure including a steel member at least partly buried in a covering layer, such as steel rebar in a concrete structure, is provided by embedding sacrificial anodes into the concrete layer at spaced positions over the layer and connecting the anodes to the rebar. Each anode is inserted into a drilled hole in the layer and is electrically attached to the rebar in the same or an adjacent hole by a steel pin which is attached to the reinforcement by arc welding or by impact. In the arrangement where the anode and the attachment are in the same hole, the pin passes into or through the anode so as to hold the anode rigidly within the hole. The hole is filled by a settable filler material.

  • Patent number: 6231730
    Abstract: A cathode frame for receiving and retaining a cathode plate for electrowinning and/or electrorefining processes is constructed as an integrally-formed frame body having a base member and side members which provide a continuous channel therethrough for retaining the peripheral edge of a cathode plate, and is further structured with a cross frame extending between the side members for receiving a cathode plate therethrough. The cross frame is sized and positioned to extend proud of the frame body thereby providing contact surfaces for striking when recovering the cathode plate from the frame. In an alternative embodiment of the invention, the cross frame is integrally formed with the side members and base member and the cathode frame is configured to retain a filter media thereagainst.
