Abstract: A nickel based single crystal superalloy comprising 7-9 wt % cobalt, 3.5-4.5 wt % chromium, 0-2.4 wt % molybdenum, 4-8 wt % tungsten, 3.5-6 wt % rhenium, 5-6.5 wt % aluminium, 6.5-8.5 wt % tantalum, 0-0.2 wt % hafnium and the balance nickel plus incidental impurities. The nickel based single crystal superalloy is suitable for use as a gas turbine engine turbine blade or turbine vane. It is of particular us on cooled turbine blades and turbine vanes which have ceramic thermal barrier coatings, because the superalloy is compatible with the ceramic thermal barrier coating to minimise spalling. The superalloy has better mechanical properties than other second-generation single crystal superalloys and has better creep strength and oxidation resistance.

Abstract: A pin to plate joint and method of making the joint comprising a plate comprising an entry side and an exit side with the plate defining cutouts, and the pin movable through the plate from the entry side to the exit side and in doing so pushes tab members at angles to the exit side of the plate at bends. The bends in the plate define an opening in the plate, and flow spaces are defined between the pin sidewall and the bends in the plate, with the tab members being heated to form melted tab material and flowing the melted tab material into the flow spaces and cooling, forming a pin to plate joint.

Abstract: An electrochemical cell having plate electrodes housed inside mating “clam shell” casing components. is described. When mated together, the casing components are form fitting with respect to the internal battery structure so as to reduce the overall size of the electrochemical package. A one-piece header containing both a glass-to-metal seal opening for a terminal lead and an electrolyte fill opening is used in conjunction with the clam shell casing.

Abstract: The present invention is directed to an electrochemical cell having plate electrodes housed inside mating “clam shell” casing components. Also, the present casing design allows for indentation structures in the casing components by virtue of them being stamped metal parts. Such indentations are not possible with traditional cylindrical and prismatic casing designs. When mated together, the casing components are form-fitting with respect to the internal battery structure so as to reduce the overall size of the electrochemical package. This provides the cell with the greatest amount of energy per unit size.
