Title: Routing of network traffic
Inventor: KELLY FRANCIS P
IPC: H04Q3/66
Filed: 1986-12-15
Granted: 1991-05-14
Abstract: ABSTRACT OF THE DISCLOSURE:         TELECOMMUNICATIONS NETWORK AND METHOD      A method and apparatus for routing traffic in a circuit switched network.  A call between two nodes interconnected by a direct link is first offered to the direct route, and if that is blocked it is offered to a currently nominated two-link alternative route between the two nodes.  If that route is busy, the call is lost, and a randomly chosen two-link route is assigned to be the new current nominated alternative route.  The strategy is particularly effective because it is simple, available routes are quickly located and once one available route is found, that same route is used for rerouting further calls until it is full.  Trunk reservation protection is applied on alternative routes.

Abstract: TITLE     "A Method of Separating Carbonaceous Coal From An Aqueous Coal Slurry"     INVENTORS             Charles E. Capes Kevin A. Jonasson William L. Thayer ABSTRACT OF THE DISCLOSURE :      In a method of agglomerating carbonaceous coal comprising first agglomerating impurity liberated carbonaceous coal, from an impurity liberated coal slurry, with agglomerating oil to form open structured, chain-like, micro-agglomerates and then forming relatively larger, less open structured more robust agglomerates from a portion of the slurry to provide a mixture of micro-agglomerates, relatively larger, more robust agglomerates, water and any inorganic impurities that may be present.  The relatively larger, more robust agglomerates are screened and then the micro-agglomerates are separated using an aerating, skimmer tank leaving an inorganic impurity laden waste water.  The micro-agglomerates are rendered buoyant by the aeration and are thus rendered separable from the inorganic laden waste water which may be further treated to remove the inorganic waste to provide water for recirculation.

Abstract: ABSTRACT (ref Fig 2) TRANSMITTER AND TRANSCEIVER FOR A COHERENT OPTICAL SYSTEM   An optical transmitter having a single optical source (10) coupled to a modulator (14) for providing an information modulated signal and an optical amplifier (13) for providing an amplified phase reference signal which signals are combined by a coupler (15) for onward transmission.  Duplex operation of a travelling wave optical amplifier 13 facilitates the implementation of a coherent optical transceiver 22 with a single optical amplifier (13). A separate reference signal oscillator, therefore, is not required at a remote receiver.  The bi-directional amplifier 13 also amplifies the incoming signal, removing the need for a separated dedicated amplifier before the receive (11).  The transceiver may be adapted for homodyne or heterodyne operation.           Figure 2

Granted: 1991-07-09
Abstract: Abstract A sensible and latent heat exchange media comprises a gas  permeable  matrix.  The  gas  permeable  matrix  provides passageways therethrough through which an air stream can flow through the sensible and latent heat exchange media.   The gas permeable matrix is formed of a sensible heat exchange material that  is  capable of absorbing  sensible heat  from a warm air stream and releasing the absorbed sensible heat into a cool air stream as the air streams flow through the sensible and latent heat  exchange  media.  A  layer  of  a  coating  composition comprising a molecular sieve is applied to at least a portion of  the  surface of  the  sensible heat  exchange  material.  The molecular sieve has a plurality of pores of a  substantially uniform  size  such  that  the  molecular  sieve  is  capable  of adsorbing moisture from a humid air stream flowing through the sensible  and  latent heat  exchange  media,  and  is  capable  of releasing the adsorbed moisture into a dry air stream flowing through the sensible and latent heat exchange media, but is not capable  of  adsorbing  contaminants  from  either  of  the  air streams.    The  sensible  and  latent  heat  exchange  media  is extremely efficient  in transferring both  sensible and latent heat between air streams.
