Title: Response system of a terminal to an incoming call
Inventor: MURATA HATSUHO
IPC: H04M11/00
Filed: 1987-05-07
Granted: 1991-08-27
Abstract: ABSTRACT         A problem with communication terminal response systems in general is that, should a particular one of multiple terminals always return a connect request message before the others, all incoming calls would arrive at that particular terminal and, there-fore, a calling user would be incapable of communicating with a desired terminal even though it might repeat origination of a call a number of times.  The system of the present invention  causes a calling party number and attribute values of a call of the in-stant when a communication was unsuccessful to be stored in a terminal and, when a message which arrives thereafter is identical in content with the stored one, delays the return of a connect request message from the terminal to thereby allow another terminal to accept the call.  The response system of the invention varies the period of time by which the return of a connect request message is delayed, every time the terminal receives a message, so that connect request messages from several terminals are prevented from conflicting, i.e., the connect request messages are received by a network at different times.

Title: Toxic gas absorbent and process for making and using same
Inventor: NELSON SIDNEY G
IPC: B01J20/04
Filed: 1988-01-22
Granted: 1993-02-09
Abstract: Toxic Gas Absorbent and Process for Making and Using Same Abstract Solid sorbents (acceptors) for noxious components, eg. SOx, NOx and HX, from gases below about 250°, specifically water-containing acceptors that have a divalent metal oxide and/or hydroxide, eg. MgO and/or CaO, coated onto an exfoliated or expanded mineral sup-port, are improved by heating them before use at a tem-perature of 400-650° for a conditioning period of at least a few minutes.  So conditioned pulverulent MgO coated onto water-laden exfoliated vermiculite (alter-natively expanded perlite) is preferred because of sorbing capacity and the ability of the magnesia-based acceptors to be regenerated at a moderately elevated temperature that precludes substantial deterioration of acceptor or equipment.  To insure immediate activity the conditioned acceptor is moistened for use. Advantageously the gas and/or the acceptor is humidifed during their contact.

Title: Viscosity reduction processing at elevated pressure
Inventor: BAIN RICHARD L
IPC: C10G9/00
Filed: 1988-01-29
Granted: 1991-12-03
Abstract: ABSTRACT      A method is disclosed for improving the transpor-tability of a hydrocarbon composition by passing an in-fluent feed stream of composition into a downcomer to provide a hydrostatic column of fluid.   The influent stream is heated by heat exchange with an effluent product stream wherein at least one of the streams is in turbulent flow.   The feed stream is pressurized by the hydrostatic pressure head to a reaction pressure of at least about 1000 psi.   The heated and pressurized feed stream is contacted with an active heat source in a reaction zone to increase the temperature of the feed stream to a reaction temperature of between about 300°C and the coking temperature of the hydrocarbon composi-tion.  The temperature differential between the active heat source and the feed stream in the reaction zone is maintained at less than about 30°C to provide a treated effluent stream which is brought  into heat exchange contact with the influent stream.  The treated composi-tion has a lower viscosity than the feed composition.

Title: Low noise magnetically tuned resonant circuit
Inventor: DIBIASE ROBERT
IPC: H01P1/218
Filed: 1988-03-28
Granted: 1991-04-02
Abstract: Abstract of the Disclosure A magnetically tuned resonant circuit having improved noise performance includes a ferrimagnetic or gyromagnetic body such as a YIG sphere which is disposed within a r.f. structure.  The r.f. structure is disposed between a pair of pole pieces of a biasing magnet and flux return path.          Several techniques are described for reducing fluctuations in magnetic fields through the gyromagnetic body.  The gyromagnetic body is isolated from conductive surfaces, or the bulk of conductive surfaces in the region adjacent to the magnetic body are reduced.  Further, a technique is also described which provides a break in the electrical continuity around the r.f. structure.  Each of these tech-nique reduce the magnitude of thermally induced eddy current flow in conductive regions adjacent to the resonant body.          It is believed that such eddy current flow produce random magnetic field variations which produce random variations in the frequency characteristics of conventional magnetically tuned resonant circuits.

Granted: 1991-07-16
Abstract: METHOD FOR ENHANCING THREE-DIMENSIONAL          INTERFERENCE CHECKING            Abstract of the Disclosure Method for use in a CAD system whereby three-dimen-sional interferences among space-oriented objects can be rapidly determined by storing a reduced granularity of the design space in the form of a three-dimensional matrix having elements which represent identification numbers of objects which occupy the design space in the subcontinuum represented by the element.  The element can be multidimensional or the element can refer to a table if more than one object occupies the associated subcontinuum.  As objects are added to the drawing, the new objects are assigned unique index numbers which are stored in all the matrix elements corresponding to all the subcontinuums occupied by the object.  Calculations for interference among pairs of objects need only be made between objects having their index number in a same element of the matrix.
