Abstract: A wind turbine journaled on a support for rotation about a substantially vertically positioned axis and employing trough-like vanes spacedly positioned around the axis and extending longitudinally thereof. A windshield is rotatively mounted on the support for surrounding and shielding at least a part of the vanes, which windshield is adjustively positioned relative to the wind to compensate for high wind speeds and resulting wind damage to the turbine.

Abstract: A four cycle rotary internal combustion engine employing two cycles of operation per rotation of the rotor and wherein an eccentrically mounted rotor with radial unbiased blades slidable therein form with the external wall of the rotor and the internal wall of the casing surrounding it, a plurality of chambers, the volumes of which vary constantly during rotation of the rotor.

Abstract: A wet cell storage type battery which may be quickly restored to a fully charged condition by the removal and replacement of its electrical generating elements or slowly recharged in the normal manner.

Abstract: Novel wall construction for frameless, multi-story buildings erected from interlocking multi-layer wall elements formed of aluminum or plastic extrusions which when snapped together in proper sequence form insulated, sound-proof inner and outer walls with ceiling and floor support for industrial, commercial and residential building purposes.
