Abstract: The method of assembling banks of battery electrodes, comprises the steps of sorting electrodes into an odd number of groups of different thicknesses (thin, medium, thick) where the thickness of two medium electrodes is equal to the sum of thicknesses of one thin electrode and one thick electrode which are equidistant from the medium electrode. Installing in alternating polarity piles of medium electrodes in any number, whereas the piles of equidistant thin and thick electrodes, are installed in pairs only. The electrodes, each of alternate polarity, are taken simultaneously, one from each pile, and moved in a horizontal plane, and are then deposited consecutively into a bank or pack of a preset or desired thickness.

Abstract: There is proposed a method of impregnation of cermet electrodes of an alkaline storage battery, which comprises the steps of reeling a sintered band stock together with a spacer element arranged throughout the entire length and width of the band stock and providing an appropriate space between the turns of the band stock, and placing said reeled band stock together with the spacer element into active solutions.

Abstract: Disclosure is made of an apparatus for applying paste upon blank strips for cermet electrodes of alkaline storage batteries. The backing strip is advanced by a drive through a bin filled with the paste. This bin is made in the form of two autonomous reservoirs having in their respective lower portions, in the walls thereof facing each other, ports with edges through which the paste can leave the reservoirs. The upper edges of these ports define, upon said reservoirs having closed upon the backing strip, an application nozzle having centering lugs made on the edges of the ports, to center the backing strip with respect to the application nozzle.

Abstract: The device or apparatus for assembling banks of battery electrodes comprises a bed which mounts feeders with electrode-containing holders, and the feeders incorporating a mechanism for maintaining automatically the upper level of the electrode pile in the holders. Disposed above the feeders is an assembling mechanism comprising a shaft, one end of which is connected to a drive ensuring its vertical reciprocating motion in alternation with a full revolution around its axis, whereas the other end of the shaft carries radially-mounted grips made with a provision for being disengaged at a certain working stroke of the assembling mechanism by a readjustable kinematic linkage which can disengage part of the grips during the preset working stroke of the assembling mechanism.

Abstract: Disclosure is made of an apparatus for winding strips, preferably in longitudinal cutting of a tape of separating material for storage battery electrodes, wherein at least two drawing rollers are connected to a drive for their rotation so as to provide for the tape movement through a cutting mechanism; at least two receiving shafts are coupled to said drive by means of a friction clutch, the shaft axes running in parallel with the axes of said drawing rollers; said receiving shafts are provided with a set of spools for winding adjacent strips on said spools of different receiving shafts; said receiving shafts are also provided with longitudinal slots extending along the entire length thereof, and spool is provided with a stop received in the longitudinal slots of the receiving shafts to provide for tensioning of the tape upon slacking.

Abstract: An apparatus for effecting impregnation of cermet electrodes of an alkaline storage battery, according to the invention, comprises a tank with active solutions which accommodates a member from which electrode stock members are suspended. The stock members are made as a set of forms, each being used for a band stock to be reeled thereon together with a spacer element. The spacer element is adapted to form an appropriate space between the turns of the band stock.The spacer element is made of individual interconnected frames forming a chain of a specified length and provided with projections on both sides of longitudinal and transverse strips constituting a frame, so as to provide circulation of an active solution between the turns of the band stock.

Abstract: Disclosure is made of a device for packing flat articles, mainly battery electrodes into a separating material, wherein a bed supports a grip which moves the article to be packed jointly with the material. Installed in line with said grip on said bed is a material feeding mechanism in the form of two reels mounted on parallel axles. The grip is linked kinematically with the carriage of the material feeding mechanism, said carriage reciprocating jointly with the grip. A guide with a slot receiving the article to be packed, is mounted on the carriage, the slot being limited by a fixed stop on the side opposite to the grip.

Abstract: A method of forming cermet electrodes for alkaline accumulators, includes the step of winding a band stock together with a counterelectrode into a roll, connecting the ends of the band stock and the counterelectrode to the opposite poles of a power source, and forming cermet electrodes by anode and cathode polarization of the band stock in an electrolyte, the band stock being assembled together with the counterelectrode and insulated therefrom.

Abstract: A device for a piece-by-piece delivery of storage-cell electrodes is described which includes a table on which a stack of electrodes is disposed. Located close to the table is a manipulator made as a swivel bar with a holder at a end of which a gripper is provided. The swivel bar is mounted in sliding bearings coaxially with a pushrod which is capable of vertical reciprocations so as to lift the bar and dro it freely under its own weight. Provision is made in the middle portion of the bar for the double-arm lever with the rollers, the lever being kinematically associated with the link of a step-by-step conveyor. The link has a right-angular recess the outside working edge of which is shorter than the inside working edge thereof, thus providing for the link to engage one of the rollers of the double-arm lever in the course of swivelling of the bar.

Abstract: An automatic device for sorting flat articles comprises a casing with a vertical sorting drum in the center, said drum being provided with posts arranged around the periphery of said drum which are intermittently turned by a drive. Each post has a manipulator sliding freely over said post and having a catch for fixing said manipulator in the uppermost position.

Abstract: A device for longitudinal cutting of a thermo-softening material into strips, such as strips of a separating material for battery electrodes comprising a roll holder, two pulling rollers having their rotation drive installed parallel and near to said roll holder, and said rollers moving the band in the course of cutting and delivering the cut strips onto the receiving shafts of a wind-up mechanism. A common shaft parallel to the pulling rollers is located under a cutting mechanism and carries electric cutters secured on arms; the hubs of said arms are fastened with the aid of intermediate sleeves on said common shaft. Both the hub and the intermediate sleeve are provided with segment teeth which interact with each other during the turning of the common shaft thereby lifting automatically the electric cutters.

Abstract: An automatic device for fixing the edge of a moving band, wherein the roll holder that feeds the band over at least one bar, is controlled by the band roll cross-traverse mechanism. This mechanism is made as an air cylinder whose chambers communicate with a system of compressed gas through a number of pipings and throttle valves provided in each of said pipings, whereas connected with their inlets between each of the throttle valves and the respective chamber of the air cylinder are nozzles adapted to provide a uniform gas discharge from both air cylinder chambers at a time. At least one of said nozzles is provided with a closure adapted to interact with the band edge, and thus serves as the band edge position detector capable of effecting control over the air cylinder operation.
