Title: Method and apparatus for decorating wood veneer
Inventor: ROBERTS JOHN JOSEPH
IPC: B41M1/38
Filed: 1988-11-28
Abstract: A method and apparatus for decorating wood veneer in which a composite is formed of a wood veneer bonded to a flexible backing sheet. An inked design of pre-determined configuration is then applied to the wood veneer's exposed surface using an ink under pressure such that the ink penetrates the surface and is held in the grain of the veneer. The design can be applied using rollers to force ink through a printing screen, ink-jet printing or air brush techniques. The flexible barking, e.g. of paper, fabric or plastics, provides support for the veneer and prevents the veneer from breaking up or cracking under the printing pressure.

Title: Wide area nodeless distributed synchronisation
Inventor: HULBERT ANTHONY PETER
IPC: H04J13/00
Filed: 1991-07-10
Abstract: A radio communication system comprises a plurality of radio transceivers which are mutually synchronised to define a synchronised group or partition by means of data transmitted on a synchronisation channel, which synchronisation channel is additional to a channel used exclusively for the transmission of traffic data. The synchronisation channels are monitored on a time division multiplex basis using synchronisation monitoring time slots and 2/3 the traffic channel data is redundantly coded. The synchronisation channel monitoring operations by the radio transceivers of the group or partition are arranged to operate in interdependence such that a predetermined proportion of the radio transceivers are at all times monitoring the sync channel. Any station which detects that its synchronisation monitoring time slot is unused by another station, retains that slot. Should it be used by another station or stations, a random reselection of slots takes place. <IMAGE>
