Patent GB-2078388-A (GB)
Title: Passive electro-optic display cell and method of manufacture thereof
IPC: G02F1/1337
Filed: 1980-06-19
Abstract: A passive electro-optic display cell comprises two glass plates 1 each of which is covered with a protective layer 3, for example of silicon dioxide, over which are electrodes 4. A bonding layer 5 is placed between each plate (1) so treated and a liquid crystal alignment layer 6. The bonding layer is of a transparent organic substance, for example a silane or an aluminate and the alignment layers are composed of a polymerizable material, for example a polyimide. A sealing frame 2 which surrounds the liquid crystal 7 between the plates is likewise composed of a polymerizable material, for example a formaldehyde phenol resin. After warming the cell construction to adjust the plate spacing, further heat is applied to produce polymerization of, and copolymerization between, the materials of the sealing frame and the two alignment layers, so that there is formed a casing which encloses the liquid crystal and protects it against contamination and from external influences. The protective layer 3 on each plate prevents ions from the plate diffusing within the cell. <IMAGE>

Title: Seismic vibrator
Inventor: ANSTEY NIGEL ALLISTER
IPC: G01V1/153
Filed: 1981-01-20
Abstract: A swinging-weight vibrator (1, 2) is driven by energy stored in a freely decelerating fly-wheel (10). The phase of the vibrator, as a function of time, is measured (at 12) to define a master (reference) sweep signal whose amplitude is made a function of the thus determined sweep rate. The use of a free downsweep provides a measure of automatic compensation for resonance in the vibrator-ground coupling. Supplementary output at low and/or high frequencies is obtained by controlled variation of the eccentricity (57-62). A plurality of vibrators may be arranged to have complementary acceleration (54, 55) and deceleration (51, 52) periods, or to be optimized for different parts of the frequency range, or for simultaneous use at spaced-apart frequencies. <IMAGE>
