Appl. No.:

D/108889

Inventors:

Jack Walker - Veedersburg IN

International Classification:

0805

US Classification:

D 8107

US Patent:

40677648, Jan 10, 1978

Filed:

Mar 15, 1977

Appl. No.:

5/777762

Inventors:

Jack S. Walker - Sylmar CA
Wilfred C. Kittler - Pasadena CA

Assignee:

Sierracin Corporation - Sylmar CA

International Classification:

H01L 3104

US Classification:

156267

Abstract:

There is described a solar cell panel consisting of an outer rigid transparent faceply of glass or plastic material to which are applied at least two layers of plastic such as polyvinyl butyral between which are positioned a plurality of solar cell wafers. A thin flexible film of polyethylene terephthalate forms the other outer surface of the panel. The panel is manufactured by laminating the materials together and allowing the margins of the plastic film to extend beyond the polyvinyl butyral layers so that the film can be brought into direct contact and sealed to a rigid base plate, forming a fully encapsulating structure. The assembled structure is then evacuated to withdraw air and to squeeze the layers together to promote adhesion. The evacuated laminated structure is then placed in an oven for applying heat and pressure to the laminated structure for permanent bonding. After cooling, excess film is trimmed from around the edges of the rigid face plate.

International Classification:

F04B 43/12
F04B 43/00

Abstract:

A pump for use with a tube, having a rotor having an axis of rotation and a plurality of rollers configured to define an orbital path about the axis of rotation, the orbital path defined by a radius, and a roller bed having a surface adapted to support the tube for peristaltic compression by one or more rollers, wherein the surface has a predetermined profile comprising a circular arc segment and at least one side segment, the arc segment having a first curvature defined by the radius, and the at least one side segment having a second curvature lesser than the first curvature.
