Abstract: ABSTRACT OF THE DISCLOSURE       A communication system is disclosed for transmitting digital information between a central station and a large number of remote stations. Digital information is identified by the relationship between A simple pulse marking signal and a time reference signal which is common to all stations, that is, the time reference signal synchronizes the operation of all the stations. The relationship of the marking signal, which does not in itself carry any digital information, to the time reference signal is initially determined by the content of the digital information. Thus, this digital information can only be subsequently determined by evaluating the relationship between the marking signal and the time reference signal. In this communication system, digital radio wave transmission is used to transmit marking signals between stations and the power lines of the power distribution system are used as the source of the time reference signal. The marking signals transmitted by radio waves are used to start and stop digital counters located at each of the stations in the communication system. The operation of these digital counters is synchronized by the time reference signal transmitted over the power lines of the power distribution system. Since the relationship between the radio wave marking signals and the power line reference signal is identified by these digital counters, the digital information is transferred from one station to another and vice versa simply by the controlled operation of these digital counters. This communication system is primarily intended for use in a power distribution system for transmitting digital information from a plurality of remote stations each having a watt-hour meter associated therewith to a central station which uses this digital information for load management and control. The central station is capable of requesting a particular one of the plurality of remote stations to transmit digital information by actuating the digital counters in the manner described above. In response to the request from the central station, the particular remote station responds by transmitting the digital information contained therein to the central station which identifies the responding remote station.

Abstract: ABSTRACT OF THE DISCLOSURE         A door seal arrangement for application to a high-frequency heating apparatus comprising a heating chamber having an access opening and an oven door for openably closing the access opening, for preventing leakage of electromagnetic waves through the peripheral area of the oven door.  In this door seal arrangement, a plurality of reactance elements of a conductive metal material or a dielectric material having a high dielectric constant are disposed between the flat surfaces of the parallel plate transmission line constituted by the oven door and the heating chamber to extend along the access opening of the heating chamber thereby forming a series resonance circuit connected in parallel with the parallel plate transmission line provided by the oven door and the heating chamber.  This series resonance circuit provides a high-frequency electromagnetical short-circuit plane at the disposed location of the reactance elements so that the electromagnetic wave components emerging from within the heating chamber to be incident at an arbitrary incident angle upon the parallel plate trans-mission line and tending to leak toward the exterior of the high-frequency heating apparatus can be reflected back toward the heating chamber.

Title: Self-regenerating method and system of  removing oxygen and water impurities from  hydrogen gas
Inventor: SIMONS HAROLD M
IPC: F17C11/00
Filed: 1978-12-19
Granted: 1982-06-15
Abstract: ABSTRACT     Oxygen and water impurities are cleaned from hydrogen, which is to be stored in tanks containing a hydride-forming metallic alloy, using a novel, self-cleaning filter system. The impurity-containing hydrogen gas is first passed through a catalyst bed comprising a catalyst which is adapted to convert oxygen in the presence of hydrogen to water. The gas then passes through an adsorbent capable of adsorbing water from the gas stream, thereby substantially removing water impurities from the hydrogen gas. The purified hydrogen gas is charged into a storage tank containing a hydride-forming metallic alloy which adsorbs the hydrogen by reacting therewith to form hydrogen-loaded metallic hydride. When the storage tank is to be discharged, the hydrogen-loaded metallic hydride in the tank is treated to release hydrogen gas therefrom. The released gas is passed back through the adsorbent, thereby cleaning the adsorbent of water impurities deposited therein when the tank was being charged with hydrogen. The hydrogen gas containing water impurities is then forwarded to a hydrogen utilization unit for further use of the hydrogen.

Abstract: ABSTRACT        A method for fabricating multiple layer interference optical films by ion beam sputtering, said films being used for mirrors in a ring laser apparatus.  An ion beam strikes a target material obliquely, dislodging molecules of the target so that they can be deposited on 2 surface serving as a base for a multiple layer interference coating.  The thickness of the coating is monitored so that the proper thickness of a given layer can be optimized to obtain the type of reflectance desired for a given light wave length.  The surface to be coated is rotated during the deposition of the layers of target material.  A stack of layers of alternating indices of refraction comprises the optical interference film.  The coating process occurs inside of a vacuum chamber where the partial pressures of the gases are carefully controlled to insure the proper ion beam intensity and optimum stoichiometry of the deposited optical films.  Prior to beginning the deposition of optical films, the ceramic substrate comprising the mirror base is bombarded by the ion beam at an oblique angle to remove surface anomalies and clean it.

Abstract: ABSTRACT OF THE DISCLOSURE           Quaternary ammonium salts are used as adjuncts to the primary catalyst of an alkali metal pyrrolidonate in the polymerization of 2-pyrrolidone using SO2, CO2 or MoO3 as initiator.  The catalysts may be recovered and recycled by washing the resultant polymer with a solvent.  The structural formula for the quaternary ammonium salt is   wherein R1, R2, R3 and R4 are alkyl, aralkyl, or aryl radicals, n is 1 or 2 depending on the valence of X, and X is a sulfate, hydrogen sulfate or halide.  Such quaternary ammonium salts reduce conversion time for polymerization and also act as color suppressors when sulfur dioxide is used as an activator at higher temperatures.  Also disclosed is the use of a cesium or rubidium pyrrolidonate as a color suppressor in the SO2 activated 2-pyrrolidone polymerization.
