Each of the one or more modules may include a plurality of electrochemical cells electrically coupled to one another, each one of the plurality of electrochemical cells including an oxygen evolution electrode (OEE), an anode, a gas diffusion electrode (GDE), an electrolyte, and a vessel and, within the vessel, the OEE, the anode, and the GDE at least partially immersed in the electrolyte.

Abstract: According to an aspect, an electrochemical cell may include a vessel, at least two instances of an anode assembly, at least two instances of an oxygen evolution electrode (OEE), and a gas diffusion electrode (GDE). In the vessel, the GDE may be disposed between mirrored arrangements of the at least two instances of the OEE and the at least two instances of the anode assembly.

Abstract: In some embodiments, a method can include delivering an electrically conductive coil into a lumen of a subject. In certain embodiments, the method can further include delivering at least a portion of an endoprosthesis into a lumen of the electrically conductive coil. In some embodiments, the method may enhance the MRI visibility of material within a lumen of the endoprosthesis.

Abstract: A stent is adapted to be implanted into the lumen of a vessel. The stent includes struts and a resonating circuit tuned to the resonating frequency of a magnetic resonance imaging system. The resonant circuit is constructed of at least one inductor and at least one capacitor. The inductor is wound about at least one of the struts.

Abstract: A gate includes a gate panel mounted on a post which provides a horizontal pivot where the pivot axis is at right angles to the gate panel and adjacent or at a bottom corner of the gate panel. The gate is carried on one side of the post so that the gate can be pulled in pivotal movement around the horizontal pivot axis so that the gate raises and folds inwardly beyond the mounting pivot to a retracted position standing up alongside the post. A winch assembly attached to the support beyond the post provides a cable which attaches to the panel at a position spaced outwardly and upwardly from the pivot so as to pull the panel to the raised position. A spring coiled at the pivot biases the panel to a mid point of its movement.

Abstract: A self cleaning screen particularly for an engine cooling system comprises a housing having a screen front wall and a rear wall in which there is provided a circular opening. The housing is divided by divider plates connecting between the front and rear walls and extending outwardly from the circular opening to outer side edges of the housing. A baffle is mounted at the center of the opening and is rotatable by a fin or an electric motor. The baffle includes a triangular front plate for closing off a part of the screen aligned with the opening together with a side plate portion which closes off the area defined between the divider plates. As the baffle rotates therefore a portion of the screen extending radially from the centre of the opening to the side edge is closed off so that air does not flow through that area allowing filter debris to fall from the screen.

Abstract: A pick-up header for a combine is designed to improve the control of the material from a windrow as it is picked up from the ground and transported to the feeder housing of the combine. Immediately rearwardly of the pick-up fingers is provided an air transportation device including a plurality of openings through which air is forced to carry the material rearwardly toward the feeder housing while allowing the escape of stones. Rearwardly of the air transportation device is a sheet which inclines downwardly toward the curved feeding surface of the feeder housing with the pick-up, air transportation device and guide sheet all pivotally mounted relative to the feeder housing. A feed roller includes a plurality of fingers which rotate with the roller about an eccentric axis so that the fingers project outwardly at the front of the roller to a length extending just to the rear of the pick-up fingers and then retract at the rear of the roller.

Abstract: A swath pick-up for a harvester provides a drive for the transverse toothed members which acts to rotate the toothed members about a transverse axis while moving them longitudinally of the axis. The drive comprises a pair of plates arranged at opposed ends of the transverse member each supporting a plurality of pairs of bevel gears mounted such that one bevel gear rotates with the plate while the other is rotated by rotation of the first to rotate the respective transverse member on a crank. The bevel gears are inter-connected either by a shaft or by an elbow casing. The first bevel gear is either fixed to the plate for rotation therewith or is rotated by an internal cam track provided on a cam plate parallel to the rotatable support plate.

Abstract: A swath pickup includes a pair of spiders one on each end of a frame and angulated with respect to the direction of travel. A forked inwardly offset arm is pivotally secured to blocks on the outer ends of each arm of the spiders in the form of a universal joint and a transversely extending member from which pickup teeth extend, extends between each offset arm on one spider and the corresponding offset arm on the other spider. The spiders are rotated by a motor and the angular relationship of the spiders causes the members and the pickup teeth to reciprocate transversely as they rotate. The offset arms enable a pickup of reduced diameter to be provided which increases the efficiency of the pickup action yet provides sufficient room at the spiders for the installation and operation of the universal joints and arms to the spiders.
