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.

Abstract: This invention applies to an electrolytic cell busbar construction for the purpose of the electrolytic recovery of metals. The construction is formed so that the gap between the electrodes can be changed easily. All parts of the construction are in the form of an integral profile longitudinally to the cell and the support lugs of the electrodes in the cell are unnotched.

Abstract: The invention relates to a separating member for separating the bottom part of an electrolytic tank from the rest of the tank space in connection with the removal of solids (6) settled onto the bottom of the electrolytic tank (1). According to the invention, in the electrolytic tank (1) there are installed support and control members (10), which form the trajectory of the separating member (11, 21, 31), so that the separating member (11, 21, 31) can be inserted in the electrolytic tank (1) and removed therefrom via a space left in between at least one rear wall (7, 32) of the electrolytic tank (1) and the electrode (2) located nearest to said rear wall (7, 32).

Abstract: The invention relates to an electrode for electrolytic refining or electrowinning, said electrode (1, 21, 41) being provided with a hanger bar (3, 23, 43) attached to the edge of one plate-like mother plate, and the edges (4, 5, 6; 24, 30, 31; 44, 49, 50) of said electrode, apart from the edge to which the hanger bar is fastened, being protected with an edge strip (11, 12, 13; 29, 32, 33; 48, 51, 52) made of some insulating material, in which electrode at least part of the edge strips is at least partly placed in a groove (7, 25, 45) made in the electrode edge. According to the invention, at least in one electrode edge (4, 5, 6; 24, 30, 31; 44, 49, 50), there is formed a groove (7, 25, 45) for the electrode edge strip (11, 12, 13; 29, 32, 33; 48, 51, 52) made of some insulating material; the front end of said groove, located at the electrode edge (4, 5, 6; 24, 30 31; 44, 49, 50), being essentially equal in width with the rear end (10, 28, 53) of the groove placed inside the electrode.

Abstract: The invention relates to an anode used in the electrolytic refining of copper, said anode (1) comprising two support parts (2), whereby the anode (1) is suspended during the electrolytic process against the electrolytic tank walls. According to the invention, in the anode support parts (2) there are formed brackets (3) for gripping the anode (1) and for supporting the anode (1) when it is being transferred from one position to another.

Abstract: Apparatus for transferring sheet-like objects from one position to another comprises a control frame including a vertical control member and a gripping device within the control frame and including a control member counterpart engaging the vertical control member of the control frame in a manner permitting relative movement of the control frame and the gripping device over a predetermined vertical range. A loading member is coupled to the gripping device for lowering the gripping device from an upper position to a lower position and for raising the gripping device from the lower position to the upper position, and a positioning member is attached to the gripping device for engaging a complementary member when the gripping device is at the lower position.

Abstract: The invention relates to a method for producing a mother plate used in electrolytic cleaning and to the mother plate which plate comprises a metal plate (1), a plate support member (2) and a plastic edge strip (6) provided on at least one of the sides (3,4,5) of the metal plate (1). According to the invention, in order to form the edge strip (6), in the mother plate (1) there is attached a mold (7) provided with an extruder (11) for extruding the edge strip material (12), so that the extruder (11) is made to proceed, with respect to the mold (7), essentially along the whole length of the mold (7), and that prior to detaching the mold (7) from the mother plate (1), the edge strip material (12), such as ethylenic acid copolymer, is rendered in an essentially solid form. Moreover, according to the invention at least two opposite sides (3,4) of the mother plate (1) are provided with an edge strip (6).
