Title: Interference minimisation mobile radio system
Inventor: OHTERU YOUICHI
IPC: H04W16/10
Filed: 1990-05-29
Abstract: The system has a control station connected to a switched telecomms network 4 and base stations 2, each base station being capable of sensing power levels of signals received on idle channels. In response to a polling signal periodically sent from the control station, each base station returns a signal indicating the detected power levels, the identifications of the idle channels, the identification of a busy channel or no-busy channel indication, and the identification of each of the base stations. The control station derives an interference table, from the received signals which defines interference coefficients between all pairs of base stations in matrix form according to the identifications of the idle and busy channels and the identifications of the base stations. From the interference coefficients a plurality of interference estimations are derived for all possible combinations of channels and base stations. A minimum value of the interference estimations is detected and the channels associated with the minimum value are assigned to the base stations. The assigned channel identifiers are communicated from the control station to the base stations. <IMAGE>

Title: Method of detecting fluid influx in a borehole
Inventor: GROSSO DONALD SYLVESTER
IPC: E21B47/18
Filed: 1991-11-04
Abstract: The present invention concerns a method of detecting the fluid influx (e.g. a gas influx) in a borehole (10) by transmitting from downhole an input signal (20) through the annulus (16) defined between the drillstring (12) and the borehole (10) thus determining and monitoring the transfer function H(SA) of the annulus. When a fluid possessing different physical properties as the drilling fluid intrudes into the annulus its transfer function H(SA) will most likely change and this detected change can be used to predict the intrusion. <IMAGE>

Title: Audio transmission over a computer network
Inventor: BARRACLOUGH KEITH ROBERT
IPC: G06F3/16
Filed: 1993-10-19
Abstract: A computer workstation includes an audio adapter card for generating a sequence of digital audio data samples, aid accumulating them into audio data blocks. These are then transferred one at a time into a queue in the main memory of the computer workstation. A first program loop on the workstation receives an interrupt from the audio adapter card indicating the transfer of another audio data block, and maintains a record of the head of the queue.

Title: An egg processing system
Inventor: KERRIGAN DECLAN
IPC: A23B5/005
Filed: 1993-10-22
Abstract: At a loading station raw eggs are transferred from trays onto a conveyor which delivers the eggs to a breaking machine. Each egg is broken and the egg white is separated from the egg yolk. The egg white and egg yolk are delivered to collecting baths either separately or together and then pumped through filters to holding tanks. The raw egg material is then passed through a pasteurising plant comprising a preheater where it is indirectly heated by pasteurised egg and a main heater where it is heated to a desired pasteurising temperature and held at the pasteurising temperature for a preset desirable time period. Pasteurised egg material is then cooled and delivered to a storage tank from which it is pumped into sterilised containers. Preferably before delivery of raw egg material through the pasteurising plant, water is circulated through the pasteurising plant and the pasteurising plant is brought to a desirable operating condition for pasteurising the raw egg material.

Title: De-icing system for a butterfly valve
Inventor: GALLO CLAUDE
IPC: F16K49/00
Filed: 1994-08-05
Abstract: A butterfly valve (4), in the cold starting system for an aeroengine, is provided with automatic de-icing wherein valve control means is connected to shaft (8) of butterfly (5) by finger (11) which is coaxial with shaft (8). The finger and shaft have slots (13, 12) and are rotatable relative to each 31 other between two stops. In one of the stop positions the slots (12, 13) are aligned (figs. 3a, 3b) and in the other the slots (12, 13) are misaligned. When the butterfly is iced up and the control means is operated to open the butterfly, the initial movement of the control means moves the finger (11) relative to the shaft (8) to the stop position in which the slots (12, 13) are aligned, thereby allowing hot gas to flow from side (6) to side (7) of butterfly (5) thereby heating shaft 8. When the shaft and butterfly are de-iced, the control means is able to continue moving to open the butterfly. <IMAGE>
