Patent number: 4542258Abstract: The present invention includes a method for applying bus bars to a solar cell by one single solder dipping operation. The bus bars are first temporarily spot attached to the pre-metallized surface of a solar cell by means of a high temperature adhesive. The solar cell and bus bars are then solder dipped allowing the solder to flow between the bus bars and solar cell surface by capillary action, adjacent the adhesive.Type: GrantFiled: May 28, 1982Date of Patent: September 17, 1985Assignee: Solarex CorporationInventors: Robert W. Francis, Joseph D. Napoli, Hsue C. Tsien

Patent number: 4521359Abstract: This invention pertains to a method of producing a composite sheet of plastic materials by means of coextrusion. Two plastic materials are matched with respect to their melt indices. These matched plastic materials are then coextruded in a side-by-side orientation while hot and soft to form a composite sheet having a substantially uniform demarkation therebetween. The plastic materials are fed at a substantially equal extrusion velocity and generally have substantially equal viscosities. The coextruded plastics can be worked after coextrusion while they are still hot and soft.Type: GrantFiled: December 4, 1981Date of Patent: June 4, 1985Assignee: Exxon Research & Engineering Co.Inventor: Hsue C. Tsien

Patent number: 4201691Abstract: An apparatus is disclosed for generating a multiple phase dispersion and distributing said multiple phase dispersion as globules in a suspension phase. The apparatus comprises a conduit for introducing a first fluid under pressure into a first zone including a porous fluid dispersing layer. This first zone is in fluid communication with a second zone through the porous fluid dispersing layer. The second zone has introduced into it a second fluid under pressure through inlets. The first fluid is dispersed as bubble-like micro droplets in the second fluid by passage from the first zone through the fluid dispersing layer into the fluid in the second zone. An outlet zone is in contact with the second zone and comprises a perforated nonporous layer having an outer and inner surface and includes a porous flow distribution layer substantially in contact with the inner second zone facing surface of the nonporous layer.Type: GrantFiled: January 16, 1978Date of Patent: May 6, 1980Assignee: Exxon Research & Engineering Co.Inventors: William J. Asher, Hsue C. Tsien

Patent number: 4169816Abstract: This invention provides an electrically conductive polyolefin composition which contains a balanced mixture of fillers which increase the extrudability of the polyolefin composition into shaped articles of improved flex strength and resistance to shrinkage. The amounts of constituents of compositions of this invention, expressed in parts by weight, are as follows: 100 parts of polypropylene-ethylene copolymer, 15.30 parts of carbon black, 0.25 to 1 part of silica, and 1-10 parts of a fiber-reinforcing agent selected from carbon fibers or mixtures of carbon and glass fibers; and when the fiber-reinforcing agent is a mixture of carbon and glass fibers, then the composition shall contain from 1 to 5 parts of glass fibers and from 1 to 5 parts of carbon fibers.Type: GrantFiled: March 6, 1978Date of Patent: October 2, 1979Assignee: Exxon Research & Engineering Co.Inventor: Hsue C.

Patent number: 4164068Abstract: A novel multicell electrochemical device having a plurality of bipolar carbon-plastic electrode structures and a novel method of making the device are described. A plurality of bipolar carbon-plastic electrode structures are formed by first molding thin conductive carbon-plastic sheets from heated mixtures of specified carbon and plastic, and then establishing frames of dielectric plastic material around the sheets and sealing the frames to the sheets so as to render the resulting structures liquid impermeable. A plurality of electrochemical cell elements in addition to the electrode structures, e.g. separators, spacers and the like, are also formed with dielectric plastic frames. The frames of both the electrode structures and the additional elements have projections on at least one surface. The electrode structures and the additional elements are stacked to form a group of items in an electrochemically functional arrangement.Type: GrantFiled: December 19, 1977Date of Patent: August 14, 1979Assignee: Exxon Research & Engineering Co.Inventors: Joseph A. Shropshire, Hsue C. Tsien

Patent number: 4124478Abstract: A thin sheet apparatus is described as having a front and a back and having a central area and a frame area disposed around the central area. The central area is made of a fluid impermeable material having substantially planar surfaces. The frame area contains two sets of supply orifices and drainage orifices which are opposite one another. The frame area also contains a plurality of channels for each orifice which connects the orifice with the central area. The pluralities of channels for the first set of supply orifices and drainage orifices are located on the front of the frame area while the pluralities of channels for the second set of supply orifices and drainage orifices are located on the back.Type: GrantFiled: February 7, 1977Date of Patent: November 7, 1978Inventors: Hsue C.

Patent number: 4117065Abstract: A method of forming a conductive carbon-plastic material having increased surface area and enhanced surface conductivity characteristics is described. A conductive carbon-plastic material is molded from a mixture containing particulate conductive carbon and plastic material. The surface of the resulting conductive carbon-plastic material is simultaneously abraded and embedded with carbon particles by the projection of a dry mixture of compacted carbon and metal particles against the surface by means of propulsion. This dry mixture of compacted carbon and metal particles is obtained by ball milling a mixture of specified amounts and sizes of carbon and metal particles. Zinc metal particles are preferred.Type: GrantFiled: May 2, 1977Date of Patent: September 26, 1978Assignee: Exxon Research & Engineering Co.Inventors: Hsue C. Tsien, Agustin F. Venero

Patent number: 4087862Abstract: A bladeless mixing device for use in a mixing system to mix streams of the same or different composition, for example, liquid/liquid, gas/gas, solid/solid, or any combination thereof. In the mixer device streams are tangentially directed into an inlet mixing chamber comprising a convergent conical cavity wherein a converging vortex is created, which is passed through an orifice into an outlet mixing chamber comprising a divergent conical cavity wherein a diverging vortex is developed, which is extracted from the outlet cavity tangentially for subsequent passage through further stages of the mixing system. The streams are combined, separated and recombined several times during the course of their passage through the mixing system which comprises a plurality of stages, until the desired mixing is obtained. The orifice size may be varied, depending upon the extent of mixing and velocity required for thorough mixing of the streams.Type: GrantFiled: October 26, 1976Date of Patent: May 2, 1978Assignee: Exxon Research & Engineering Co.Inventor: Hsue C.
