  • Patent number: 6701708
    Abstract: A Stirling cycle engine comprises a substantially sealed engine block that defines a working fluid space, a hot path and a cold path. A heat source and a heat sink are configured to keep the hot path and the cold path at different temperatures. The engine includes a valve chamber that is communication with the working fluid space, the hot path and the cold path. A valve is moveably positioned within the valve chamber between at least a first position and a second position. The valve defines a passage that, in the first position, places the working fluid space in communication with the hot path and, in the second position, places the working fluid space in communication with the cold path. A regenerator positioned within the passage.

  • Patent number: 4999246
    Abstract: A glass laminated structure includes a core of curable flowable material sandwiched between first and second glass panels. A pair of frame members sealed to the panels with an ultraviolet curing adhesive overlap marginal portions of the panels so that an overlapping portion of the core abuts the peripheral edges of the panels to absorb stress and inhibit delamination. The laminating apparatus includes platens with vacuum ports for securing the panels to the platens without excessive panel deformation, recessed portions for proper frame member alignment, and elastomeric seals supplanting the usual vacuum grease. The methodology proceeds by retaining the glass panels and frame members in position using the platens, and sealing the frame members to the panels. Then, the curable flowable material is introduced so that it flows between the frame members to abut the peripheral edges of the glass panels.

  • Patent number: 4439392
    Abstract: A method of making a glass laminated structure comprising retaining first and second glass panels against first and second platens respectively, using differential fluid pressure. The panels are held in spaced, generally parallel relationship and a curable flowable material is introduced into the space between the panels. The flowable material is then cured to provide the glass laminated structure.
