Abstract: The disclosure relates to any improved display system for holding display panels, photomurals, banners, signs or the like and in a generally upright, but angularly adjustable, position and particularly to a collapsible lightweight system that is easily assembled with the item to be displayed or collapsed for transport or storage. The display system can be used indoors as a stand alone support or outdoors with a stake-down system or stabilizing counter weights.

Abstract: Methods of manufacturing a liquid crystal display ("LCD"); specifically, a multi-color LCD, e.g., a red-green-blue ("RGB") LCD. The methods include the steps of: (1) depositing a twist agent on a first substrate, the twist agent becoming an in situ twist agent, (2) bringing a second substrate into proximity with the first substrate to form at least one interstitial region between the second and first substrates, (3) introducing liquid crystal ("LC") having an initial pitch into the at least one interstitial region proximate the in situ twist agent and (4) stimulating the LC and the in situ twist agent to cause the LC and the in situ twist agent to mix in situ, the in situ twist agent changing the initial pitch of the LC.

Abstract: A cholesteric liquid crystal display ("LCD") and methods of operating and manufacturing the LCD. The LCD includes: (1) a controllable cholesteric liquid crystal (CLC) located between first and second substrates, the controllable CLC selectively exhibiting an "on" state and an "off" state and having a circular polarity of a predetermined handedness when the controllable CLC is in the "on" state and (2) a circular polarizer, located proximate the first substrate and having a circular polarity of a particular handedness, that cooperates with the controllable CLC to increase the difference between the relative brightness of the "on" state and the "off" state, whereby a contrast ratio of the cholesteric LCD is increased.

Abstract: Surfactant-containing multistable cholesteric liquid crystal displays exhibit ultra fast response times with both video speed and gray scale capability.

Abstract: A light modulating apparatus containing cholesteric liquid crystals capable of indefinite zero field retention of optical images, including full color and complete gray scale capability, is described. This invention is predicated on establishment of zero field multistable liquid crystal domains representing a continuous distribution of states ranging from the highly reflective planar to the light-scattering focal-conic structures. The zero field multistable domain structure stability is achieved by controlling solid surface-liquid crystal boundary interactions to provide essential equalization of the total system energy of each of the domain structures. This is the first time this equalization, and thus zero field multistability, has been achieved without the use of a polymer gel addition to create rigid polydomains in the liquid crystal mix.

Abstract: A structurally stabilized bistable cholesteric display. The display has a back plate and a front plate with a liquid crystal material disposed therebetween. The liquid crystal material is homeotropically aligned at least at the substrate and is held in alignment by a securement matrix forming agent. The material is thermally annealed to align the helix axis of the liquid crystal molecules parallel to the substrates and a polymer may be used to secure the molecules in this position.

Abstract: A merchandise display assembly comprising a plurality of modular sections adapted to be assembled stacked relationship. The assembly is of tubular design and each section has a plurality of elongated side members, the lateral ends of which are secured together. The upper and lower edges of the side members are provided with portions for interfitting the modular section with subjacent and superjacent modular sections when the sections are stacked. Ribs extend outwardly from the outer surfaces of the side members to which merchandise display cards or holders may be attached for displaying the merchandise. The ribs may differ in number, size and spacing to accommodate different types of merchandise display cards and holders.

Abstract: A process for making a decorative panel uses a backboard made of polycarbonate plastic material having a pair of substantially parallel spaced apart walls secured by a plurality of parallel spaced apart ribs disposed between the walls. A decorative laminate is glued to the backboard. In lieu of the decorative laminate, a plurality of profiles may be used to make an exhibit panel of slatwall construction.

Abstract: A spectacle display device wherein the nose piece (12) is removably mounted to an acrylic rod by clip (4) and the interaction between the serrated back (22) of the nose piece and the ridge (20) along mounting face (8) permits relative angular placement therebetween.

Abstract: A display wall assembly including a slatwall panel which comprises the baseboard to which a plurality of elongated profiles are affixed in spaced, parallel relationship, thereby forming a horizontal groove therebetween, a shelf inserted into the horizontal groove, and provided with friction means interposed between the shelf and a portion of the profile to effect the bonding engagement of the shelf with the profile. Stop means engaged with the shelf move into abutting engagement with the slatwall profile to prevent accidental disengagement of the shelf from the slatwall panel.

Abstract: A forwardly and downwardly sloping display of tender, delicate, loose exposed produce or the like, which is continually bathed in a current of cool air, is partially covered by open-ported transparent domes which permit physical access to the produce for inspection, selection and withdrawal without need for opening or removal of the domes. An important effect of use of the domes is to significantly reduce moisture loss from the produce, while permitting sufficient interchange of air through the dome port to maintain desired coolness and restrict the growth of spoilage microorganisms.

Abstract: A cholesteric guest-host liquid crystal composition having a positive dielectric anisotropy and consisting of a positive nematic host component, an optically active cholesteric component, and a tetra-azo dichroic dye guest component having a dichroic ratio of at least 0.72.

Abstract: An electronic timepiece including timekeeping means, an electro-optical time display, and a circuit for setting the display is disposed within an electrically conductive case and an electrically conductive, optically transmissive face cover. A battery is coupled to energize the timekeeping means continuously and the display setting circuit selectively. The electrically conductive face cover and the electrically conductive case are insulated from one another and constitute electrodes of a switching circuit for selectively connecting the battery to energize the display circuit. The battery is electrically connected in series with the conductive case and display circuit, and the display circuit is electrically connected in series with the conductive face cover and battery, whereby the display circuit may be selectively energized by simultaneously contacting the exterior conductive surfaces of the face cover and case with a conductive body disposed outside of the case.

Abstract: The preparation of a semiconductor substrate for epitaxial deposition and the deposition of a solution from which the epitaxial film is formed is carried out at room temperature. The solution is deposited on the condensing surface in two discrete layering operations, the first of which ensures complete wetting of the condensing surface, the second of which ensures junction formation at a prescribed depth. The procedure is particularly useful in forming P Type epitaxial films on N-Type gallium phosphide substrates.
