TL;DR: In this article, a thin layer of an electrically conductive fibrous assembly having a rigid through-hole bearing current collector disposed on its outside surface is used for electrolyzing water or an aqueous solution using a cation exchange membrane.
Abstract: In a method for electrolyzing water or an aqueous solution using a cation-exchange membrane provided between an anode and a cathode, the improvement wherein one or both of the anode and cathode are composed of a thin layer of an electrically conductive fibrous assembly having a rigid through-hole bearing current collector disposed on its outside surface, and the electrolysis is carried out while maintaining the two electrodes, the cation exchange membrane and the current collectors in the integrally pressed state.

TL;DR: In this article, a secondary, high temperature electrochemical cell especially adapted for lithium alloy negative electrodes, transition metal chalcogenide positive electrodes and alkali metal halide or alkaline earth metal-halide electrolyte is disclosed.
Abstract: A secondary, high temperature electrochemical cell especially adapted for lithium alloy negative electrodes, transition metal chalcogenide positive electrodes and alkali metal halide or alkaline earth metal halide electrolyte is disclosed. The cell is held within an elongated cylindrical container in which one of the active materials is filled around the outside surfaces of a plurality of perforate tubular current collectors along the length of the container. Each of the current collector tubes contain a concentric tubular layer of electrically insulative ceramic as an interelectrode separator. The active material of opposite polarity in elongated pin shape is positioned longitudinally within the separator layer. A second electrically conductive tube with perforate walls can be swagged or otherwise bonded to the outer surface of the pin as a current collector and the electrically insulative ceramic layer can be coated or otherwise layered onto the outer surface of this second current collector. Alternatively, the central pin electrode can include an axial core as a current collector.

TL;DR: In this article, an electrically driven rail or track bound vehicle which can be supplied with electrical power from an overhead wire is described, which includes a current collector carrying at least one bow trolley, with the current collector being adjustable to varying levels.
Abstract: An electrically driven rail or track bound vehicle which can be supplied with electrical power from an overhead wire. The vehicle includes a current collector carrying at least one bow trolley, with the current collector being adjustable to varying levels. A width of the bow trolley is automatically variable in such a manner that, with the current collector being adjusted to a low level, the bow trolley is narrow and with the current collector being adjusted to a high level, the bow trolley has a wide width. The width of the bow trolley is variable continuously with height variations of the current collector.

TL;DR: In this paper, the parent patent describes a device for making a loadbearing, electrically insulating connection between two lengths of a trolley wire (overhead electrical conductor); the connecting device comprises two parallel glass fibre-reinforced, rod-type plastics insulators fixed to cross-beams, each insulator has a circumferentially grooved sleeve of highly electrically insulation material.
Abstract: The parent patent describes a device for making a load-bearing, electrically insulating connection between two lengths of a trolley wire (overhead electrical conductor); the connecting device comprises two parallel glass fibre-reinforced, rod-type plastics insulators fixed to cross-beams, each insulator has a circumferentially grooved sleeve of highly electrically insulating material. Metal skates act as guides, along the lower edge of which current collectors can slide. In this addition, the grooved zone of the sleeve on the rod insulators is restricted to those regions in which the lower face of the plastics rod insulators is higher than the slide track for the current collectors as defined by the lateral skates. Typical uses include a phase insulator or a section insulator. The current collectors do not slide over the grooved lower face of the rod insulators and therefore dirt does not tend to collect in the grooves. The insulators maintain their insulating capability over long periods.

TL;DR: In this article, the number of cycles, the position of the discharge curve on high rate discharge, and the electrode impedance were found to depend on the quality and size of the collector surface and on the compression acting upon the electrode group in the cell.

TL;DR: In this article, the current collectors are forced in the protruding direction by two compression coil springs 15 and the bottom part of the collector is formed in an arc shape, with a concave part at the center of the bottom.
Abstract: PURPOSE:To securely contact the current collectors to rails which have curvature in the vertical concave or convex direction slidingly by bearing the supporting member which supports the current collectors at the location over the central part of the current collectors so that the supporting member can be freely moved back and forth, and applying a force in the direction the current collectors are protruded by springs. CONSTITUTION:Current collectors 11a-11c are supported by the supporting member 12 at the location over the central part of the current collectors in the forward and rearward directions, and where the center of the rocking shaft of the supporting member 12 passes, so that the current collectors can be freely moved up and down. The front and rear ends of the bottom part of the current collectors are formed in an arc shape. A concave part is formed at the center of the bottom part thereof. Front and rear contact surfaces 23a and 23b are slidingly contacted with the power supplying rails 9a-9c. The current collectors are forced in the protruding direction by two compression coil springs 15. In this constitution, the contact surfaces 23a and 23b of the current collectors 11a-11c contact securely with the power feeding rails 9a-9c.
