  • Patent number: 4231828
    Abstract: A machine and method comprising a stack of cards, a stripping feeder for stripping the bottom card from the stack and moving a series of such cards with an intermittent motion to a series of feed rollers which convert such intermittent motion into a constant velocity and for spacing the cards one from another. A tape coated with magnetic material is laid on the surface of each card by a guiding device after the card has passed through the feed rollers and the combination is fed between a heated roller and a reaction roller which are driven synchronously with the cards. The heated roller is pressed against the cards at a constant pressure exerted by an air cylinder to seal a portion of the magnetic coating to each card.

  • Patent number: RE31151
    Abstract: Solar cells are manufactured by a simplified method in which a single protective layer acts as an anti-reflection coating and an encapsulation. In cases where the junction is formed by ion implantation techniques, the same layer also serves as the implantation oxide. In addition, this multi-purpose layer may also serve as a mass analyzer, allowing the desired species of ions to reach the surface of the semiconductor but blocking the heavier undesired species. The necessary contacts may be formed prior to implantation, and the use of alloyed aluminum contacts with aluminum oxide passivation permits a simplified contacting procedure. A fully automatic contacting method and configuration for linear materials is also disclosed.
