摘要:
A system and method for evaluating responses to broadcast programs, such as television programs, includes an instructional signal modulated onto a signal transmitted concurrently with the television program, or time-multiplexed with television signals. At each of a plurality of remote receiving stations, one or more members of a remote audience has the opportunity to respond to a task or situation presented in the television program by entering a response vocally or on a keyboard. The system may include a video game machine suitable for playing commercially available games such as an NINTENDO game or a SEGA game, and wherein such game may be played back from a recording. The system includes response evaluation circuitry, a memory responsive to the instructional signal for storing acceptable responses, a comparison circuit for comparing responses entered at the keyboard with those stored in the memory, circuitry for scoring responses in accordance with commands from the instructional signal, and a recording device for providing a permanent record of the audience score at the remote station. Electronic circuitry for evaluation and scoring purposes may be located at a remote station and/or a central location. Multiple players at a common game may be ranked in their performance, and games may be interrupted for a sponsor's message, and wherein a response to the message may serve as a basis for an enhanced score.
摘要:
In an illuminating apparatus having an electric light source housed in a container permitting light to escape upwardly towards an object supported above and in close proximity to the light source, the improvement comprising two horizontal, vertically spaced sheets having apertures in vertical register disposed above the light source, said sheets acting as light baffles, so that light escapes upwardly in the shape of spreading light beams. The neck surfaces of the apertures are minimized and made non-reflective, so that observers are protected from the glare of the light source and from reflections of light from components of the apparatus.
摘要:
Glare-free illumination of three-dimensional objects in a rock garden setting is disclosed. Artificial light is generated in a void space in a man-made rock, below and in close proximity to the object to be illuminated, shielding the eyes of observers from a direct view of the light source. Light shines upwardly in the shape of an inverted light cone enveloping the object and is only indirectly visible by its reflections from the illuminated objects, such as plants, trees and sculptures. The minimal light path reduces scattering of light, power consumption and lamp size. A flexible and adjustable suspension system is disclosed, ensuring the horizontal position of the supports for the objects placed thereon, thereby ensuring the vertical position of the illuminated objects, irrespective of surface configuration of the simulated rock garden or the angle of the ground upon such multiple-rock garden may be placed.
摘要:
A substantially glare-free, directional lighting of three-dimensional objects is provided which artificial light is generated at a central point which is recessed, in close proximity to, and below the object to be illuminated. The light shines both directly upwardly, as well as downwardly against a reflective surface and then upwardly in the direction of such object in the shape of a predetermined light cone penetrating the underside of and substantially enveloping the object without significant scattering of light. A compartmentalized grille above the light source surrounds the lower end of the object and shields the eyes of observers from direct view of the light. The upwardly reflected light is centripetally and indirectly visible by its reflections from the illuminated object. The disclosed arrangement of components permits multi-directional centripetal viewing, and particularly the glare-free viewing by a plurality of juxtapositioned observers, for instance persons grouped around the illuminated object in a circle. A tree holder and illuminating apparatus having similar characteristics is disclosed.

Articles of manufacture are disclosed for the controlled delivery of pest controlling substances. Methods for producing such articles and utilizing them in pest control programs are also described. Laminated articles are provided which comprise one or more layers containing active pest control and pest attractant substances and which allow the controlled release of the pest controlling substance from within the laminate to the surface of the laminate so as to maximize efficiency against target species in the surrounding environment. The laminated structure also permits prolonged, controlled release of pest controlling substances and properly timed combinations of such substances that might otherwise be prematurely dissipated, decomposed or inefficiently applied. Various combinations of polymers materials and active agents and a number of different laminated structures are utilized to optimize efficient use of the pest controlling substance against a variety of target species.
摘要:
Disclosed are devices and systems for the indirect, substantially glare-free, directional lighting of three-dimensional objects, such as plants and outdoor sculptures. Artificial light is generated at a central point which is recessed, in close proximity to, and below the objects which may be exposed to rain or other sources of water. The light is directed upwardly through transparent areas in a water-tight housing in the shape of a predetermined light mantle substantially enveloping the object without significant scattering of the light, which is indirectly visible by its reflections from the illuminated object. When illuminating objects such as a flower arrangement, a disclosed device permits lighting the inside of such flower arrangement, as well as its outer reaches. The devices permit substantially glare-free viewing by a plurality of observers grouped around the illuminated object in a circle.
摘要:
Disclosed is a method permitting above-ground heap leaching of metal bearing ores in below-freezing temperatures by utilizing one or more insulating layers deposited on the principal ore body to be leached. One of said layers is an insulating ore layer covering multiple leach liquor outlets positioned above said principal ore body. Other insulating layers may be comprised of a flexible sheet and a crust of frozen leach liquor.
摘要:
Disclosed is a hollow, elongated heap leaching device for use in above-ground leaching of metal bearing ores. The device has an annular cross-section, an inlet opening near its upper end, a restriction or closure at or near its lower end and narrow slits in its walls above the restriction or closure. The cross-sectional area at its lower end must be sufficiently large to allow it to unsupportedly rest vertically on a leach pad or layer of ore while ore is piled against it.
摘要:
An improved leaching method for metal bearing ores, wherein removable, void-forming members are placed near the bottom of the ore body and removed during the leaching process, causing partial internal collapse and shifting of the ore, thus exposing additional ore surfaces to the effect of the leaching solution.
