Title: Improvements relating to separating apparatus
Inventor: MORRIS CHRISTOPHER PHILIP
IPC: A24B1/04
Filed: 1992-07-17
Abstract: The separation chamber (23, Fig 1, not shown) has an upper outlet (25, Fig 1) and a lower outlet (27). The lower portion of the chamber has a pair of plates (26) which are inclined downwardly towards the lower outlet and which have apertures arranged in zones. The apertures in adjacent zones are angled in opposite directions, one set being inclined to the surface of the plate in a direction away from the lower outlet and the apertures in an adjacent set being inclined in the opposite direction. The lower outlet (27) has a side wall (33) with a number of apertures inclined upwardly at an angle of 70 DEG  to the axis of the outlet. Air is fed through these apertures from plenum chambers to create a venturi effect negative pressure below the lower outlet, resulting in a zero pressure area in the outlet. This enables the heavier material to fall from the chamber under gravity. The apparatus can be used to separate tobacco leaf and stem, tea, cereal. <IMAGE>

Title: Time synchronization and demodulation of received digital signals
Inventor: JAMAL KARIM
IPC: H04L7/08
Filed: 1992-09-09
Abstract: A method for improving time synchronization of digital data signals in receivers in mobile telephone radio systems uses more than one known data sequence e.g. SYNC and CDVCC, to provide a plurality of timing recovery functions and based on these, one or more optimal sampling points for demodulation of the received signals. By using existing data sequences in each frame, the disclosed method provides improved time synchronization without increasing transmission overhead. A transversal filter generates the correlation function between a received signal and the known data symbols within that signal. This is used as the impulse response estimate in generating a timing recovery function. <IMAGE>
