Abstract: A multi-compartment bird shelter that may be assembled with a minimum of mechanical fasteners and which may be assembled as a multi-tiered structure is disclosed. The shelter is supported, by a support flange, on a vertical pole and includes a plurality of individual compartment modules that are pie shaped with vertical divergingly spaced walls and a bottom surface. A spacer element place coaxially over the pole is larger than the pole so as to define a gap between the pole and the spacer element. The spacer element rests upon the support flange, and individual compartment modules are coupled to the pole by inserting a hook structure of the module into the gap defined between the pole and the spacer element. A plurality of like sized and shaped modules are arranged around the pole in side-by-side fashion and are similarly coupled to the pole so as to define a tier of compartments. Subsequent tiers of compartments may be similarly assembled atop existing tiers.

Abstract: A solid state double layer capacitor includes an organic electrolyte doped with a soluble salt to render the electrolyte ionically conductive.

Abstract: Double layer capacitors incorporate electrolytes having relatively high pH whereby reduced leakage current is attained as well as greatly extended back-up times.

Abstract: Novel sulfide, polysulfide, selenide and polyselenide compositions are provided which are useful as ionic conducting solid electrolytes. Electrical energy storage devices utilizing such electrolytes are also provided.
