Title: Memory disc addressing device
IPC: G11B21/08
Filed: 1980-02-15
Abstract: A device is provided for determining, notably in a disc memory system, a complete track number of a track on a disc-shaped record carrier D on which the numbers of tracks are laid down in groups. The area on the disc occupied by addresses can be reduced if each track only carries its address within the group and not the group address as well. The device comprises means for combining a track number Sm within a group as read with a trial group number g which can be varied in an increasing or decreasing sense to achieve the correct complete track number. The difference between said combination and a value of the complete track number S' which is estimated on the basis of the displacement speed V of a positioner P is determined. If the absolute value of this difference is smaller than half the number of tracks in the group Sg, the combination of the track number in the group and the group number then obtained is the value of the correct complete track number. The implementation of the device by means of a programmed digital signal processor is also covered by this application. <IMAGE>

Title: Evaluating Notes by X-ray Fluorescence
IPC: G01N23/223
Filed: 1980-09-30
Abstract: To determine whether a bank note (2) is valid, either in a note sorter or in a separate unit, part of the note is illuminated with X-rays (10) and the resultant fluorescent X-rays (13) are detected and counted. A marker element such as barium in the form of barium sulphate is incorporated in place of part of the filler in intaglio ink used in bank notes. Different note denominations can have different combinations of markers to produce different fluorescent X-ray energies, which can be detected and analyzed to control sorting of the notes into the respective denominations at high speed. This arrangement also permits detection of worn notes and notes which are stuck together. An X-ray tube or radio-active source (8) has a fail safe shutter (11) and collimating shield (9). Alternatively the source may be annular with an intrinsic Germanium detector positioned on its axis. The presence of a note over the lead back-plate 6 is detected by photocells 7. <IMAGE>

Title: A technique for reducing the effect of reflections from the sea or other surface on radar and other electromagnetic receiving/transmitting apparatus
IPC: G01S7/28
Filed: 1980-11-24
Abstract: The efficiency of radar and other microwave equipment is sometimes reduced because of reflections of the sea or land surface. Where the equipment includes an array of antenna elements it is possible to change the beam shape, (or, in the case of a receiver, the angular sensitivity distribution) and the invention proposes doing this in response to changes in a reflective property of the surface so as to reduce the adverse effects of the reflections. For example, in very smooth sea conditions it may be desirable to broaden the beamwidth so that the reflected image arrives at the antenna at a node in the sensitivity pattern; whilst in rough sea conditions the reflected image, being diffuse, may not cause such a problem, making it desirable to narrow the beamwidth in order to reduce the effects of, for example, clutter.

Title: Radio communication systems
Inventor: HARRIS ANDREW JOHN
IPC: H04B7/155
Filed: 1983-02-02
Abstract: A communications single carrier frequency repeater includes a transmit- ter circuit 10 and a receiver circuit 12 connected to a common antenna 14 via a switch 16. The circuits 10 and 12 are connected by a delay circuit 18. A logic processing circuit 20 is provided to control the operation of the repeater. The radio frequency carrier is switched on and off at such a high rate that in effect a receiver of the interrupted signal receives signals as a continuous carrier. The bandwidth of the receiver is such that the first sideband of the amplitude modulated switching waveform does not fall within the passband of the receiver filter. Thus, if the carrier being interrupted is either frequency or amplitude modulated, the receiver can still extract the audio signals therefrom without being affected by the interruptions of the carrier. <IMAGE>
