  • Patent number: 4826777
    Abstract: An array for sensing the relative intensity of electromagnetic radiation at a plurality of locations employs a network of photodiodes and non-photoresponsive diodes. A first terminal of each photodiode, e.g. the anode, is electrically connected to a common point which is one terminal of the array. The non-photoresponsive diodes are connected in like-polarity series. The second terminal of each photoresponsive diode is connected to a different connection of non-photoresponsive diodes in the string. The array is scanned with a voltage ramp signal and each change in current flow indicates an illuminated diode. The particular voltage at which current flow changes discloses which photodiode is illuminated. Embodiments of the novel array can be made monolithically without a significant number of conductor cross overs.

  • Patent number: 4823326
    Abstract: Vibrator seismic sources are operated concurrently to reduce the time required for acquiring the data for a seismic survey. Separate seismic records are produced for each of the concurrently operated vibrator seismic sources. Frequency sweeping pilot signals are generated for each of the separate vibrator seismic sources concurrently in a sequence of at least four sweeps. The pilot signals for each vibrator source have a plurality of separate phase angles during the sweeps. The seismic signals produced by the concurrently operated vibrator seismic sources are detected for each of the sweeps. The detected seismic signals are correlated separately with each of the corresponding pilot signals which were used to drive the vibrator seismic sources that produced the detected seismic signal. The correlating process produces first and second separate correlated records for each of the sweeps.

  • Patent number: 4822679
    Abstract: A thermal insulation is formed by simultaneously spraying ceramic fibers and a binder at a surface to be covered. An aqueous binder is prepared prior to application to the fiber during the spraying operation. The binder includes an organic component which provides necessary wet and green adhesion to the substrate surface and wet and green cohesion to the newly formed lining prior to firing of the sprayed-on layer. The binder also includes an inorganic component which functions at and after exposure to a high temperature to secure the ceramic fibers to the substrate and to one another. Drying and firing of the layer develops strength in the inorganic binder. Known ceramic fibers such as alumina-silica amorphous fibers, alumina-silica-zirconia fibers, polycrystalline mullite fibers, alumina fibers, mineral fibers, or combinations thereof, and the like may be employed. The fiber may be precoated with the organic binder.

  • Patent number: 4816120
    Abstract: A method of electrodepositing a doped compound semiconductor film including tellurium and a metal selected from Group IIB of the Period Table of Elements by adding an effective concentration of dopant ions to the electrolyte bath. Cadmium telluride, mercury cadmium telluride and zinc cadmium telluride may be doped with copper, silver and gold.
