Abstract: A method is disclosed for determining whether to transmit from a first unit to a second unit, where the transmission is one of a first type and a second type. In the method, a signal from the second unit is received at the first unit, and the strength of the signal as received at the first unit is measured. A determination is made of whether the transmission is of the first type or the second type, and a first threshold is selected if the transmission is of the first type, or else a second threshold is selected if the transmission is of the second type. The measured signal strength is then compared to the selected threshold, and the transmission proceeds only if the measured signal strength exceeds the selected threshold.

Abstract: Method for automatically determining whether a communication trunk is operating properly without having to take the trunk out of service and without the need of a craftsperson to initiate the testing of the communication trunk. The communication trunk is tested for continuity and integrity on a periodic or aperiodic basis.

Abstract: A medical support system intended to centrally manage medical information generated by more than one hospital and permit medical information interchange among hospitals with easy operations. The system includes a plurality of storage units for storing medical information about patients, an entry unit for entering identification information for identifying a specific patient, an identifying unit for identifying storage units that store medical information about the specific patient on the basis of the identification information from the entry unit, and an access unit for accessing the storage units identified by the identifying unit by storage units identification information to read the medical information about the specific patient.

Abstract: A liquid distributor for a packed liquid-vapor contact column includes a header tank; a liquid distribution plate having vapor riser passages and a multiplicity of discrete reservoir cells each having an aperture for flow of liquid therefrom into the column; and conduits for feeding liquid from the header tank into each cell. The liquid distribution plate preferably has a uniform criss-cross structure with alternating vapor riser passages and reservoir cells of identical shape and size. The conduits may have two or more sections each feeding a discrete group of reservoir cells from a location of the header tank at an elevation spaced from that of the other section(s). The distributor compensates for column sway or tilt when mounted on, for example, a ship.

Abstract: A dielectric resonator antenna having a resonator formed from a dielectric material mounted on a ground plane. The ground plane is formed from a conductive material. First and second probes are electrically coupled to the resonator for providing first and second signals, respectively, to or receiving from the resonator. The first and second probes are spaced apart from each other. The first and second probes are formed of conductive strips that are electrically connected to the perimeter of the resonator and are substantially orthogonal with respect to the ground plane. The first and second signals have equal amplitude, but 90 degrees phase difference with respect to each other, to produce a circularly polarized radiation pattern. A dual band antenna can be constructed by positioning and connecting two dielectric resonator antennas together. Each resonator in the dual band configuration resonates at a particular frequency, thereby providing dual band operation.

Abstract: A liquid-vapor contact column is packed with at least one layer formed of a plurality of structured packing sheets orientated to provide liquid-vapor contact in the axial direction of the column and arranged so that, viewed in the axial direction of the column, packing sheets in the body of the layer are in one or more sections in which at least one band surrounds a central core, said band being formed of segments in which the packing sheets in each segment extend rectilinearly in a different direction to those in the adjacent segments in the same band. The packing sheets in the body of the or each layer can be arranged in a plurality of abutting sections or in a single section.

Abstract: In the purification of air to remove water and carbon dioxide and other contaminants prior to cryogenic separation of oxygen and nitrogen, water and carbon dioxide are adsorbed on a solid adsorbent and are periodically desorbed to regenerate the adsorbent by the passing of a heated regenerating gas such that the quantity of heat added to the regenerating gas to produce desorption is no more than 90 percent of the heat of adsorption liberated during the adsorption of the water and carbon dioxide. The process is applicable to removing other contaminants from other gas streams also.

Abstract: A process is set forth for the selective removal of water, CO.sub.2, ethane and C.sub.3 + hydrocarbons from gas streams, particularly a natural gas stream comprising primarily methane. The process comprises contacting the gas stream with an adsorbent material consisting exclusively of one or more compounds which are basic (i.e. compounds which, when contacted with a pH neutral aqueous solution, cause such solution to have a pH greater than 7.0) and which are mesoporous (i.e. compounds which have moderately small pores providing a surface area less than 500 m.sup.2 /g). The key to the present invention is the use of a single homogenous adsorbent without sacrificing performance. Typical mesoporous adsorbents which are useful in the present invention include zinc oxide, magnesium oxide and, in particular, activated alumina.

Abstract: A dual-band octafilar helix antenna operational at two frequencies, while maintaining a relatively small package size. The dual-band octafilar antenna is manufactured by disposing radiators and a feed network onto a flexible substrate and forming the substrate into a cylindrical shape to obtain the helical configuration. The dual-band octafilar helix antenna includes four active radiators which are matched to a first frequency and disposed on a radiator portion of the flexible substrate. Four additional radiators, which may be either passive or active radiators, are matched to a second frequency, are also disposed on the radiator portion of the substrate and interleaved with the active radiators. At least one feed network is provided on a feed portion of the substrate that provides 0.degree., 90.degree., 180.degree., and 270.degree. signals to active radiators.

Abstract: In a medical data managing system, a plurality of medical data are first classified based on a classification item such as sorts of medical examinations. Thereafter, the classified medical data are stored in the same optical disk, or the same clustered data recording region of the optical disk in order to effectively search/retrieve desirable medical data from a plurality of optical disks based upon the classification item covering this desirable medical data.
