Abstract: A liquid-filled electro-optic display cell employs an elastomeric diaphragm (25) to seal a filling orifice (24) in the cell side wall. The orifice is surrounded by a rim (51) and the diaphragm is retained over the rim in such a way as to seal the orifice while remaining free to flex over central portions of the orifice. This retention may be effected by means of an annular washer (55) and clamping pin (56). In this way, sealing is effected and thermal expansion accommodated. The cell is filled by turning it until the orifice is uppermost and filling it until a convex meniscus (52) is formed above the rim to ensure that the diaphragm seals the orifice without introduction of bubbles.

Abstract: A parabolic collapsible rooftop microwave antenna (12, 13) for direct satellite-to-consumer TV transmission pivots in the direction of the aperture axis about a horizontal pivot axis (29'a, b) in response to excessive wind forces. The antenna has a cross-head theodolite-type mount (28) adjustable for azimuth and elevation, with a horizontal pivot that provides axial displacement if the axial wind force exceeds a predetermined threshold force. This limits the torque transmitted to the roof on which the antenna is mounted to a reasonably low level. Various torquesensitive horizontal pivots are described including a torqued pivot bolt, torqued slide bolts (43a, b) disposed in arcuate slots (42) for limit-stop action, shear pins for quick release action, and biased springs for collapse and self-restoration to the initial vertical position in response to transient wind force exceeding a threshold force set by the spring bias.
