A ring seal (11) adapted for installation in an annular recess (13) between a housing (15) and a rotating or reciprocating shaft (17). The seal (11) consists of a resilient ring cup member (19) having a ring wedge member (21) inserted in the center recess (25) of the cup member (19) to wedge the opposing lips (29) and (31) of the the cup member (19) outwardly into a sealing relationship. A spring (23) maintains the force against the wedge member (29).

The invention relates to the utilization of wind energy and increasing the effects thereof for power generation. Amplified wind turbine apparatus is disclosed wherein ambient inlet air is prerotated in a first air rotation chamber (B) having a high pressure profile increasing the turbulence and Reynolds number thereof and a second rotation chamber (C) adjacent and downstream of the turbine has a low pressure core profile whereby flow across the turbine is accelerated and thereafter exits the turbine apparatus through a draft anti-interference device (D) which eliminates interference with ambient winds at the outlet of the turbine apparatus. Pivotable vanes 12 controlled in response to prevailing wind direction admit air to the chambers and aid in imparting rotation. A central core 20 may be utilized for creating the desired pressure profile in chamber B.

The invention relates to apparatus for collecting solar radiation rays and for converting the radiation rays into a concentrated beam of parallel rays having a fixed orientation. The apparatus includes an optical system for collecting and concentrating the solar radiation rays and for converting the rays into concentrated beam of parallel rays. A system of mirrors is utilized to provide a concentrated beam of parallel rays which remain fixed in orientation as the optical system is rotated around a tracking axis. The concentrated beam of fixed orientation is then utilized for supplying thermal energy to a stationary solar appliance.

A spherical bearing including an inner ball having an opening for receiving a shaft and a spherical outer surface. A circular outer race including a plurality of circumferentially spaced sections extending around the inner ball for snugly receiving the inner ball. A groove extends circumferentially around the race producing a thin wall portion therebelow which permits the opposed side portions to flex relative to the ball for maximizing the physical contact between the inner surface of the race and the spherical outer surface of the ball.

This invention relates to a solar appliance apparatus for utilizing solar thermal radiation to supply heat to a heating and cooking surface. The apparatus includes a housing permanently stationed inside a residential structure and the like. The housing contains a heat transfer medium and a radiation receiver carried in heat exchange contact with the medium. A heating and cooking surface is carried by the housing in heat exchange relationship with the heat transfer medium. A radiation pipe extends through the exterior wall of the building structure to deliver a concentrated beam of solar radiation rays to the radiation receiver.

Solar heating and cooking apparatus

An apparatus is provided for converting thermal energy such as solar energy into mechanical motion for driving fluid pumps and the like. The thermal motor comprises an inner concentric cylinder carried by a stationary core member having a cylindrical disc plate fixed adjacent a lower portion thereof and extending radially therefrom, and an outer concentric cylinder rotatably carried on the disc plate defining a space between the inner and outer concentric cylinders. A spiral tubular member encircle the inner concentric cylinder and is contained within the space between said inner and outer cylinders having a first portion connected to the inner concentric cylinder and a second portion connected to the outer concentric cylinder. A heated fluid is conveyed through the tubular member and is periodically cooled causing the tubular member to expand and contract, thus causing the outer concentric cylinder to reciprocally rotate on the base plate accordingly. The reciprocating motion of the outer concentric cylinder is then utilized to drive a pump member in a pump chamber.
