Abstract: ABSTRACT OF THE DISCLOSURE         A super-radiant light source having an output with a low temporal coherence well suited, for example, to optical inertial sensor applications, includes a single mode optical waveguide such as an optical fiber having its core doped with an active laser material, such as neodymium.  Pump light is coupled into the optical fiber at an intensity sufficient to produce a significant amplification of the spontaneous emission. The reflectivity at the exit end of the fiber is low enough so that even with a high gain for the light in one traverse through the fiber, the fiber is operated well below threshold for laser oscillation.  The result-ing emission is of high intensity, but has a low temporal coherence.  In one form, the pump light is coupled into one end of the fiber and a dichroic filter is interposed in the light path between the pump light and the optical fiber to pass pump light into the core and reflect the spontaneous emission of the active material back into the core and toward the output.

Abstract: METHOD OF RECOVERING HYDROCARBON FROM OIL SHALE      ABSTRACT OF DISCLOSURE                           (D# 79,008-F) Hydrocarbons may be recovered from crushed and ground oil shale by contacting the oil shale material with a free oxygen containing gas such as air in a fluid environment at a tempera-ture range from 30 to 43 °C to remove organic fragments from the polymeric kerogen component of oil shale by oxidative scissions.          The oxidation is conducted using a liquid phase solvent for the organic fractions removed from the kerogen.  Preferred solvents are naphthalene, tetralin and phenanthracene.  The solvent-organic fraction solution is then separated into solvent and organic fraction by sublimation with the solvent being recycled.          The residual solids comprising oil shale material and unoxidized kerogen is then subjected to a bake-off to recover additional organic material from the kerogen.  In addition to recovering a portion of the organic content from the kerogen, the oxidative scission reaction increases the susceptibility of the kerogen to recovery by pyrolysis under milder conditions than the unoxidized oil shale material.  The pyrolysis is conducted at a temperature from 400°F to 750°F for a time period from 0 to 2 hours.

Title: Load balancing for cellular radio telephone systems

IPC: H04W16/06
Filed: 1986-02-04
Granted: 1988-04-19
Abstract: ABSTRACT OF THE DISCLOSURE Balancing of loading of cells in a cellular mobile radio telephone system is performed by periodically determining the channel utilization of each cell, computing a representative voice channel occupancy level, and attempting to hand-off calls from cells with higher voice channels occupancy levels to adjacent cells with lower voice channel occupancy levels.  Voice channel occupancy levels of cells are measured and compared with threshold values, and the results of the comparisons are used to direct cells to enter predetermined states.  In one state, complete cell blockage is prevented by directing cells to hand-off calls to adjacent cells.  In another state, voice channels are preserved for incoming hand-offs by directing the cell to deny access to mobile transceivers initiating new calls.  Cells may assume a combined stage wherein both of these functions are performed simultaneously.  Cells are selected as hand-off candidates for hand-offs initiated to more evenly distribute loading throughout the cellular system in accordance with cell state (i.e., voice channel occupancy level) and measured signal strength at the cells of the calls attempted to be handed off.                           - i -

Abstract: Abstract A mass flow meter on the Coriolis principle comprises two parallel straight measuring tubes (2, 3). An oscillator (11) drives the measuring tubes in opposite senses at a fundamental oscillation and a superimposed harmonic. Sensors (14, 15) receive measuring signals from which an uncorrected mass flow (Q1) is derived. A frequency determining circuit (30) determines from a measuring signal (U1) the values of the resonance frequencies (f1,  f3) of the fundamental oscillation and harmonic for the purpose of deriving therefrom a correcting value (k) which takes axial stresses in the measu-ring tubes (2, 3) into account to determine a corrected mass flow (Q2).   In this way, a mass flow meter can be made which has slight lateral deflec-tion and gives accurate measuring results despite the occurrence of axial stresses.            Fig.1

Abstract: BURST-SWITCHING COMMUNICATIONS SYSTEM            ABSTRACT:      A distributed-control burst-switching communications system with fully integrated voice and data services, and with processing capacity sufficient to support T1 or higher transmission rates. The system may include a high-speed hub switch located at a point of high-traffic concentration in the network and a plurality of link switches.  The switches are interconnected by time-division multiplexed communications links.  Each switch includes one or more ports.  Each port provides access to the system for a control processor, an end-user, or another communications system.  Within each switch, there is switching intelligence for routing a burst toward its destination port.  A burst is a variable-length sequence of bytes which represents, for example, a block of data or a spurt of voice energy as sensed by silence/voice detectors located at voice ports.  Within a communications link, a burst is transmitted one byte at a time in an assigned channel of sequential frames of the time-division multiplexed link.  The routing intelligence at each switch employs dynamic allocation of bursts to channels within communications links such that any channel of a communications link is allocated only when a burst is being transmitted therein and such channel is otherwise available for transmission of another burst.

Abstract: ABSTRACT   Magnetic resonance imaging (MRI) method and device for reducing movement artefacts.     Images obtained by means of known MRI measurements contain artefacts such as blurring and ghosting due to, for example breathing, cardiac or stomach movements of a patient under examination. An MRI method is proposed where the starting instant of a number of measurement cycles during a movement cycle is translated in time with respect to a reference point of time of a movement cycle during successive movement cycles. The above-mentioned movement artefacts are thus avoided.

Abstract: Abstract of the Disclosure Fluid-flow control apparatus and method are disclosed by which magnetically-positionable elements within a rigid body can be externally manipulated using a controlling source of magnetic flux.  The relative attractive forces which bias internal magnetic elements into normally-closed sealing engagement are substantially altered by repositioning the magnetic elements in response to the controlling magnet flux. Complete sealing or isolation against back flow through the valve under conditions of net positive outlet pressure is inhibited by the internal double-acting sealing elements which respond in unified manner to the controlling magnetic flux.

Abstract: VERTICAL BLENDER WITH TAPERED HELICAL-STIRRER                 ABSTRACT OF THE DISCLOSURE     The present  invention  is directed to mixing apparatus having a relatively large diameter tapered screw flight which decreases in diameter to one-half of that diameter at the top portion of the screw, while maintaining constant pitch between such screw flights.    The  mixing  screw  is  disposed  within  a container  structure  having  an  input  feed  at  the bottom thereof.  The material to be mixed is carried in the center of the container from the bottom to the top thereof in a column, while forging the material in a downward motion circling down the sides of the vessel.   Because each flight of the screw decreases in diameter, the material to be mixed is forced from the central column for intermixing into the downward flow  at  different  speeds  creating  a  gentle  and turbulent mixing action.
