Abstract

1402137 Double glazing unit RESEARCH FRONTIERS Inc 24 July 1972 [26 July 1971 (2)] 34600/72 Heading E1R [Also in Division H4] In a seabed cell of the type comprising two planar plates 2, 3 connected to their edges to define a volume 1 occupied by a liquid or liquid suspension, the amount of deformation of the plates when the cell is vertical, caused for example by hydrostatic pressure, is reduced by controlling the amount of liquid (and other liquid, if present) in the cell before it is sealed. Thus if a vertical cell is initially filled with liquid via a tube 6, Fig. 3, a hypodermic syringe or rubber bulb may be used to suck out liquid until the pressure at a point somewhat below the cell centre is substantially atmospheric. Some inward and outward bowing may remain, above and below the point. The liquid may also be removed by squeezing the plates 2 and 3 until they are flat. If the volume of liquid initially supplied corresponds to the undeformed volume, it is merely necessary to remove excess air by sucking or squeezing. The cell may be filled when in the horizontal position. Inward bowing of the cell may be prevented by the provision of spacers (beads or parallel elongate members) between the plates, making it possible for the pressure throughout volume 1 to be below atmospheric so that the beads are gripped between the plates. The beads, preferably of the same density as the liquid may be mixed with the liquid prior to its introduction into the cell. As particularly described, the cell is a light valve, at least one of plates 2, 3 being transparent (the other may be reflective), containing a suspension of particles in a liquid. Application of an electric field via conductive coatings 11 on the plates aligns the particles to increase the transmissivity of the suspension. If the plates were bowed as in Fig. 3, the transmission would be non-uniform due to the increased thickness and reduced field strength at the cell centre. Reference is also made to alignment of the particles by a magnetic field, but without details. When plates 2, 3 are both transparent, the cell may be useful as a window.
