Abstract: In order to gather information on the reception of video channels in a household or other location equipped with a television receiver, partinent data such as identification and viewing time are injected into an assigned minor area of the TV picture at the receiving location. The injected data, appearing in digitized form in the assigned area where the TV picture has been blocked out, are picked up by a photosensor juxtaposed with the CRT screen of the receiver, or possibly from a video output thereof, and are fed to a processor for transmission over a telephone line with or without intermediate storage to an evaluation center. A data injector inserted between an antenna and an input terminal of the receiver blanks the incoming video signal of a selected channel during a small fraction of a frame-scanning cycle, while the CRT beam sweeps the assigned area, and replaces it with the digitized data. Alternatively, the blanking of the assigned area and insertion of channel identification may take place at the transmitting station.

Abstract: The highly lithium exchanged forms of zeolite X, particularly the low silica forms of zeolite X which contain more than ninety equivalent percent lithium cations, have been found to exhibit extraordinary capacities and selectivities for nitrogen adsorption. Such adsorbents are to a surprising degree effective in separating nitrogen from gas streams such as air and mixtures of nitrogen with less polar substances such as hydrogen, argon and methane. Pressure swing adsorption separation processes are well suited to take advantage of the exceptional properties of these adsorbents.

The process according to the invention makes it possible to fabricate anti-reflection layers having extremely low reflectivity compared with known layers; as a result, it is possible to fabricate structures with high dimensional accuracy in materials with metallically polished surfaces, in particular aluminium, tungsten or silicides. The process is used in photolithographic processes in structuring metal conductor tracks for highly integrated semiconductor circuits. <IMAGE>
