Title: Battery
Inventor: RAJLAKSHMI PURKAYASTHA
IPC: H01M50/562
Filed: 2016-11-08
Abstract: A battery 16 has electrodes of a first type (10a, 14a, figs 1 and 2) in an electrochemical zone within pouch (housing) 18 and electrode regions 10b and 14b of a second type ("protrusions") which protrude from the electrochemical zone. The battery also has contact tabs 22 (22a and 22b) electrically connected to the protruding regions 10b and 14b wherein the width of the protruding regions are larger than the width of the tabs. The protrusions extend beyond the electrochemical zone but are contained within a seal 20 in pouch 18 and they may be kept away from contact with the surrounding atmosphere. The contact tab connected to the protrusion 10b of the anode may be formed of nickel, while the contact tab connected to the protrusion 14b of the cathode may be formed of aluminium. The contact tabs may be ultrasonically welded to the protrusions. When a current is drawn into the battery, the temperature of the anode, cathode and contact tabs rise, typically because of Joule heating. By controlling the width of the protrusions relative to the width of the contact tabs, the rate of heat removal out of the electrochemical zone via the protrusions may be controlled. The battery may be a lithium sulphur battery.

Title: Protecting aircraft inpingement surfaces from adhesion of surface contaminants
Inventor: STEPHEN ROLSTON
IPC: B64F5/40
Filed: 2017-05-25
Abstract: An aircraft impingement surface 12 is coated with a material 20 having Bingham plastic properties, including a yield stress, to protect it from surface contaminants 52, such as insects or airborne debris or dirt. The yield stress may be greater than the shear stress experienced by the coating during pre-take-off manoeuvres of the aircraft. The material acts as a solid and may be adhesive or have low surface tension to capture and bind the insects or dirt. The yield stress of the material may be less than the shear stress experienced by the coating during take-off or climb of the aircraft. This results in the material flowing as a viscous liquid, carrying the insects or dirt away from a leading edge 12 or leading edge slat (fig.4B,14), for example. The benefit is reduction of turbulent flow, and therefore aerodynamic drag, arising from surface imperfections caused by the contaminants, improving fuel efficiency of the aircraft.
