Patent EP-0294890-A3 (EP)
IPC: G06F15/16
Filed: 1988-06-06
Abstract: A data processing system including a host computer linked 
by a gateway to a parallel, general purpose computing system comprising 
a plurality of interconnected nodes. Each node includes a data processor 
and a communication processor. An information packet originated by one 
of the nodes is routed by one or more hardware linked communication 
processors in the other nodes until it reaches its destination node 
whereat it is transferred by the communication processor to its 
associated data processor thereby removing it from the communications 
network of the data procesing system. Deadlock and starvation are 
avoided by a technique termed class climbing. In class climbing an 
acyclic directed graph is superimposed on the physical communications 
network by assigning a direction to each of the physical links. The 
class of an information packet remains unchanged whilst it is travelling 
according to the direction of the acyclic directed graph associated with 
its class. However the class of a packet is incremented by one each time 
it has to change its travel from according to, or against, the direction 
of the acyclic directed graph associated with its class.  
     Another feature of the switching of information packets 
between the communication processors is that a communication processor 
receiving an information packet initiates a request for the delivery of 
the information packet from its neighbour rather than vice versa.

Title: Digital signal demodulation
IPC: H03D3/00
Filed: 1988-02-24
Abstract: A method of demodulating a high frequency carrier 
signal having at least one parameter modulated by a low 
frequency modulating signal comprises translating the 
signal to a low intermediate frequency, digitising the 
translated intermediate frequency signal at a 
correspondingly low sampling rate and applying terms from 
the resulting digital time series to a non-linear 
processor to produce an output representative of the 
instantaneous value of the modulated parameter. By 
deriving an instantaneous value of the modulated 
parameter removes the need to use a high intermediate 
frequency for the carrier and enables the signal to be 
sampled at a low sampling rate.

Title: Transfer system for electrophotographic printing apparatus
IPC: G03G15/16
Filed: 1989-03-13
Abstract: A transfer mechanism in a full color 
double transfer electrophotographic print engine including 
mechanisms at a photoconductor to transfer web 
transfer station, and a transfer web to final image receptor 
transfer station are shown. Relatively conductive developer 
materials having successively increasing triboelectric 
charge characteristics are used to develop sequential images. 
Conductive plates (36, 37), displaced away from the transfer station 
along the direction of travel of the transfer belt (20) are used as 
one electrode for applying an electrostatic field at each 
transfer station. A key parameter of the transfer 
mechanisms is a bulk resistivity of the transfer belt (20) in the 
range of 10⁷ to 10¹⁰ ohm centimeters and a surface 
resistivity for the belt in a range of 10⁷ to 10¹⁰ ohms per 
square. A selectively operable compression roller (45), 
compressing paper (35) paper and transfer belt (20) against a rubberized 
idling roller (59) at one of the transfer stations increases dwell 
time in the transfer station. The compression roller (45) 
automatically falls to a cleaning station and is rotated by 
another rotary member to clean it between transfers. The 
use of conductive developer materials also tends to eliminate 
halo problems common in color electrophotography.

Patent EP-0363716-A3 (EP)
IPC: B29C48/09
Filed: 1989-09-25
Abstract: The invention concerns an extrusion die 
assembly, especially for use where accurate centering 
of a mandrel is important. The assembly includes the 
first member having a mandrel (20) projecting therefrom and 
an extrusion passage (22) generally in line with the 
mandrel (20), which extrusion passage is, at one end, of 
cross-section to conform with a passage carrying 
extrudate for the extrusion head and which merges, 
over its length, into an extrusion passage at the 
other end, at least partially surrounding the root of 
the mandrel. This member (20) is adjustably located in an 
outer member (12), which together with the mandrel defines 
an extrusion nozzle. Since the extrusion passage 
passes through the first member, it is possible to 
provide positioning means for the first member and the 
mandrel without interfering with extrudate's flow.

Title: Process for the preparation of porous polymer beads
IPC: C08J3/12
Filed: 1989-10-25
Abstract: Isotropic porous polymer beads having a high 
controllable surface porosity and large pore diameters 
from about 0.002 to about 5 microns are produced from 
solutions of an acrylonitrile polymer or a copolymer by 
a thermally-induced phase separation process including 
intensively shearing the polymer solution into small 
droplets. The use of mixed solvent non-solvent 
combinations as solvents for the polymers, and 
preferably reducing the polymer content in solution to 
below 10 percent produces high pore content, 
substantially spherical beads having a morphology 
ideally suited to the chromatography of large molecules, 
such as proteins, and for enzyme-binding.
Patent EP-0367138-A3 (EP)
Title: Matrix interconnection system
IPC: G11C11/4097
Filed: 1989-10-27
Abstract: The described embodiment of the present invention utilizes the 
regular nature of a large number of arrays by providing a grid 
scheme In the array to provide a low impedance point to point 
interconnection. In the described embodiment of the present 
invention a DRAM includes a number of leads (52, 54, 56) running 
perpendicular to the sense amplifier (30, 32, 34, 36) layout. For 
a given signal, each lead is interconnected to a bus lead (52) 
running parallel to the layout of the sense amplifiers. Thus each 
lead in the parallel array carries a portion of the current. In 
addition, in this scheme it can be assured that a substantial 
number of leads will be near any particular sense amplifier which 
is drawing on the signal provided on the grid array scheme. 
Because of the close proximity of the parallel conductors, the bus 
lines to the sense amplifiers need not be as wide as feeder lines 
in the prior art. Because the parallel grid leads and the bus 
leads may be much smaller than the leads in the prior art, they 
may be more compactly arranged in the array.

Patent EP-0335563-A3 (EP)
IPC: H04L12/00
Filed: 1989-03-21
Abstract: A high capacity metropolitan area network (MAN) is described. Date 
traffic from users is connected to data concentrators at the edge of the network, 
and is transmitted over fiber optic data links to a hub where the data is switched. 
The hub includes a plurality of data switching modules, each having a control 
means, and each connected to a distributed control space division switch. 
Advantageously, the data switching modules, whose inputs are connected to the 
concentrators, perform all checking and routing functions, while the 1024x1024 
maximum size space division switch, whose outputs are connected to the 
concentrators, provides a large fan-out distribution network for reaching many 
concentrators from each data switching module. Distributed control of the space 
division switch permits several million connection and disconnection actions to be 
performed each second, while the pipelined and parallel operation within the 
control means permits each of the 256 switching modules to process at least 
50,000 transactions per second. The data switching modules chain groups of 
incoming packets destined for a common outlet of the space division switch so 
that only one connection in that switch is requied for transmitting each group of 
chained packets from a data switching module to a concentrator. MAN provides 
security features including a port identification supplied by the data concentrators, 
and a check that each packet is from an authorized source user, transmitting on a 
port associated with that user, to an authorized destination user that is in the same 
group (virtual network) as the source user. Distributed control of the space 
division switch is implemented by dividing that switch into disjoint sets of 
connection and switching elements and controlling each such set with a different 
controller. These controllers communicate via a separate control network with the 
data switching modules which request circuit connections.

IPC: G01N29/14
Filed: 1989-11-07
Abstract: A method and apparatus for monitoring the 
structural acoustic signature of a structural member 
in response to a transient load, corresponding to 
detected vibration frequencies transmitted by the 
structural member including the fundamental and 
harmonic frequencies of the structural member, to 
determine changes in structural integrity and to 
determine the nature and type of transient loads. 
The structural acoustic signature of the structural 
member in a first condition in response to a first 
transient load is compared to a structural acoustic 
signature from a second transient load whereby 
differences in the signatures correspond to the 
occurrence of changes in the elastic qualities or 
condition of the structural member. The signatures 
are preferably evaluated in the frequency domain. 
The nature and type of transient load can be deter­
mined by evaluating the waveform shape of B struc­
tural member in response to the unknown load against 
a history of waveform shapes corresponding to known 
loads. A plurality of remote structural members 
such as highway bridges may be monitored by a central 
station.
