摘要： A trailer hitch accessory with a lighted sign, auxiliary brake lights, and a protective cover for a trailer hitch. A rectangular enclosure equipped with lights is fastened to a trailer hitch by a trailer hitch connection. The trailer hitch connection encloses and protects the trailer hitch from damage from the elements. The rectangular enclosure has lights contained therein, which are connected to the trailer hitch electrical connection by an electrical connector. A removable translucent sign may be placed within the enclosure to be backlit by one or more lights within the enclosure. When the operator of a vehicle activates his headlights, then lights within the enclosure come on lighting the sign for viewing at night. When the operator of the vehicle applies his brakes, it lights not only the brake lights on the vehicle, but also the auxiliary brake light panels on the enclosure.

摘要： An optical filter arrangement comprises at least two optical filter elements including a transparent substrate and an optical coating typically comprising at least two overlying optical thin films. The coating defines a first patterned area and a second surround area bordering the first area. The first area has substantially the same optical transmittance characteristics as the second area and different optical reflectance characteristics over at least a portion of the visible spectrum. The distinction between the first area and the second area is visually perceptible when viewed from one side of the optical filter arrangement and is substantially visually imperceptible when viewed from the opposite side of the optical filter arrangement. As a result, a coloured pattern or logo is only visible when viewed from one side of the filter arrangement. The invention extends to a method of forming such an arrangement.

摘要： A decorative lamp assembly includes an enclosure body having a cover portion and an electric bulb unit fixed in the enclosure body. A bowl-shaped transparent rotary member is mounted rotatably in the enclosure body and is located between the bulb unit and the cover portion. A pattern unit is indicated on the rotary member. A plurality of transparent rotary disks are formed with pattern units and are mounted rotatably within the rotary member between the bulb unit and the cover portion so that rays of light emitted from the bulb unit pass through the rotary disks and the rotary member and penetrate partially the cover portion to display silhouettes of the pattern units of the rotary disks and the rotary member on the external surface of the cover portion. A driving unit rotates the rotary disks and the rotary member.

摘要： A marquee false front consists of a sheet of pennant cloth of one color, e.g. yellow, of dimensions equal to those of the desired marquee false front. The front surface of the sheet, except for letters-defining areas, is coated with matter which inhibits light passage through it. The matter's color is one, contrasting with the pennant cloth's color. Pockets are formed around the sheet's periphery about its back side. These pockets accept interlocking rods, which together form a frame, used to taut the pennant cloth sheet as well as to attach it to a marquee to form its false front.

摘要： A display device comprises a pair of transparent substrates sandwiching therebetween a liquid crystal material which is reversibly switchable between transparent and forward light scattering states. Disposed behind the device, between it and a source of illumination, is a louver means comprising a plurality of elongated vanes of a dull black, light absorbent color. The louver is so disposed relative to a viewer of the device and the source of illumination as to provide a continuous, black background for the device.

摘要： A visual indicator, such as an exit sign, having a display panel which is a closure for the front of a housing containing a light source. The panel includes means for providing both a first transmitting visual image such as the word ''''Exit,'''' and an area for a second light transmitting visual image such as an arrow. A mask-like means is mounted on the panel for movement between a plurality of positions, and has a plurality of visually different images which can be selectively registered with the second image area providing different second images. The panel and mask-like means have releasable means, accessible only when the panel is at least partially removed from the housing, to fix the mask-like means in each of the plurality of positions.

摘要： In this specification, the gist of the technical disclosure resides in a thin-wall, light message-transmitting element which can be masked, peeled, cut, punched or molded in selected patterns and placed over a glass or plastic reflector, or over a glass or plastic lens, or over a translucent or light-diffusing element to convey a message from a light reflector or a backlighted device. The element is constructed of a piece of opaque material or light-transmitting or filtering material, such as thin-wall acrylic, styrene, butyrate, polycarbonate or other type of material having the properties of light blockage, transmission or filtering. The element is constructed in such a way as to include preformed designations of outlines such as squares, rectangles, triangles, diamonds, circles and the like which a user may mask, peel, cut or punch in selected sequences to form symbols such as an arrow, numerals such as house numbers, and letters to form words such as ''''Caution,'''' ''''Stop,'''' ''''Slow, '''' a person''s name or initials, and the like. Such a light message-transmitting element is constructed with tabs or other fastening devices corresponding with receiving inserts on the glass or plastic reflector, lens or translucent or diffusing light element, for attachment and detachment for the purpose of readily detaching the light message-transmitting element to perforate the marked portions in whatever selected sequence desired to form the indication or message desired to convey upon light being either reflected from the front or transmitted from behind, depending on whether used with a reflecting element, a lens, or translucent or light-diffusing element being backlighted. There are obviously many other ways in which the element can be attached and detached to the light reflector or backlighted device, such as adhesives, heat-sealing, solvents, sonic welding and the like. Once the desired indication or message has been made on the element by masking, peeling, cutting or punching the selected marked portions, the element is then placed by whatever attachment means selected over the reflecting element, lens or translucent or light-diffusing element, to form either a reflective device or backlighted device having a directive sign or message. It is also possible to make the message-transmitting element a permanently assembled part of the reflector or backlighted device by solvent cementing or sonic welding to the faces thereof. The membranes would be punched out in place without removing the element from the reflector or backlighted device.
