Title: Sending a communication unit parameter to a plurality of radio communication units; encryption key updating
Inventor: ROSAUER MATTHEW M
IPC: H04L9/08
Filed: 1996-09-13
Abstract: An updated communication unit parameter, particularly an encryption key or an encryption map index, is sent to a plurality of communication units during a first time period using either a group update method or an individual update method (step 401, Fig.4). A first set of communication units that did not receive the updated parameter in the first period is determined (402), eg. from the absence of an update acknowledgment by those units, and the updated parameter is then sent to the first set during a second period using only the individual update method (403). During a first subperiod of the second period the updated parameter may be sent to each unit of the first set based on a primary region of operation comprising a coverage area where the communication unit was last heard from or most likely to be currently operating (step 501, Fig.5). The subset of the first set which did not receive the parameter update in last step (501) is determined (502), and then during a second subperiod of the second period, the updated parameter is sent to each unit of that subset based on a secondary region of operation comprising a coverage area in which the unit is next most likely to be currently operating (503). During a third subperiod of the second period, the updated parameter is sent to a unit when an update opportunity occurs (504, 506), that is any event that indicates that a communication unit is active, such as a request for the parameter or an attempted communication.

Title: Centrifugal separator with repulsive magnetic thrust bearing
Inventor: SAMWAYS ANDREW LEONARD
IPC: B04B5/00
Filed: 1998-02-11
Abstract: A centrifugal separator (10, Fig 1) comprises a housing 11 through which extends a spindle on which is mounted a centrifuge rotor 20. The rotor is mounted on journal bearing bushes 31 and 32 that are lubricated by the liquid supplied at pressure to the rotor and the weight of the liquid-filled rotor is carried by magnetic repulsion thrust bearing 40 comprising permanent magnets 43, 46 secured one each to the housing and rotor. The spaced magnets run without contact noise and frictional losses, improving rotational speed available from the supply pressure, and lateral (radial) instability that is inherent between repelling magnets and normally disliked puts a radial bias on the journal bearings which may result in quieter running by inhibiting vibration, particularly when the journal bushes are starved of liquid supply during wind-down. Alternatively or additionally, supply pressure induced lift of the rotor may be borne by a magnetic repulsion thrust bearing (360, Fig 3). The magnets may be permanent and/or electromagnets.
