Abstract: Self-cleaning electrochemical cells, systems including self-cleaning electrochemical cells, and methods of operating self-cleaning electrochemical cells are disclosed. The self-cleaning electrochemical cell can include a plurality of concentric electrodes disposed in a housing, a fluid channel defined between the concentric electrodes, and an electrical connector positioned at a distal end of a concentric electrode and electrically connected to the electrode. The electrical connectors may be configured to provide a substantially even current distribution to the concentric electrode and minimize a zone of reduced velocity occurring downstream from the electrical connector. The electrical connector may be configured to cause a temperature of an electrolyte solution to increase by less than about 0.5° C. while transmitting at least 100 W of power.

Abstract: Apparatus for handling documents comprises an inlet 30 for receiving documents, a transfer means for transferring documents from the inlet to a secure or securable location and deposit means, wherein the transfer means is operable, in use, to transfer documents between the inlet and a deposit position adjacent the securable location, said deposit means comprises a plunger 50 and movable members 523b, 523c wherein the movable members 523b, 523c are arranged to move along the plunger 50 as the plunger 50 urges documents into the securable location.

Abstract: A helmet with large vent openings includes a vent shield to prevent the penetration of foreign objects and a vent airflow regulator positioned over the vent shield so as to regulate the amount of airflow allowed within the interior of the helmet. The vent shield is attached to the foam liner during the in-mold process, while the vent airflow regulator is positioned behind the vent shield after the in-mold process in a post-applied manner. A foam insert is positioned behind the vent airflow regulator and also has vent openings.

Abstract: An adjustable ski pole having a clamping mechanism for locking the pole in a desirable position. An outer shaft telescopically receives an inner shaft which is engaged by a clamping mechanism. The clamping mechanism includes a housing having a first portion attached to the outer shaft and a split portion defining a longitudinal gap. A circumferential slot separates the split portion from the first portion along about half the circumference. The split portion has a first lug on one side of the gap and a second lug on the other side. A lever is pivotably connected to the first lug. A link is pivotably connected to the lever to define an off-center linkage. A pivot rod engages the second lug, and a threaded connector adjustably connects the link to the rod. When the lever is pivoted from the release position to the clamping position, the gap width is reduced.
