Patent GB-2272348-A (GB)
Title: Broadcast relay transmission system
Inventor: FINNEY ANDREW BRANDON
IPC: H04N7/08
Filed: 1993-12-07
Abstract: A broadcast television relay transmission system comprises a relay station (16) which receives (17, 18) a Tv signal from a parent transmitter (14) and re-transmits it over a relay transmitter (20, 21). Local information e.g. a local weather map may be required to replace the signal from the parent transmitter. To this end a computer (22) has a non-volatile store (23) to store the various components of the weather map, background map and icons etc., and a local studio centre (30) transmits instructions identifying the required picture components and their desired locations. The signal may be transmitted by telephone link (32) and modem (34), or may be included in the signal transmitted by the parent transmitter (14) and downloaded via a receiver/decoder (26). It is thus not necessary to maintain a video bandwidth landline or similar link with the relay station. <IMAGE>

Title: Latch assembly for a fire door
Inventor: COHRS RICHARD B
IPC: E05B65/10
Filed: 1994-06-01
Abstract: A latch assembly (16, 18) for a fire door (10) includes a push pad (12) for emergency exit which is connected to a rod (15) to transfer motion of the push pad to the latch assembly. The latch assembly includes a platform attached to the fire door, a linkage assembly (131) attached between the rod and a latch bolt (158), and a deadlock arm assembly (160) attached to the platform. The deadlock arm assembly is movable between a first position to block movement of the linkage assembly and a second position to allow movement of the linkage assembly. A fire fuse assembly (182) is also attached to the linkage assembly to move the deadlock arm assembly out of its first position blocking movement of the linkage assembly at normal room temperature. The fire fuse assembly is configured to melt at temperatures substantially above normal room temperature to prevent engagement between the fire fuse assembly and the deadlock arm assembly, effectively preventing movement of the deadlock arm assembly. <IMAGE>

Title: Slew-rate limited bus driver
Inventor: FATTORI FRANK RAOUL
IPC: H03K19/003
Filed: 1994-08-31
Abstract: A driver amplifier for a bus feeds single polarity signals of controlled slew rate to the bus. The slew rate control is effected by a feedback capacitor C connected from the output to the input of the amplifier. A clamp Q8 is provided for selectively connecting the input of the amplifier to a reference voltage so that when the amplifier is quiescent signals on the bus cannot be fed through the capacitor to turn on the amplifier. A current source S1 and a switchable current sink S2 are connected to the input of the amplifier to charge the capacitor to produce the slew rate controlled transitions. Another driver amplifier of the same design but using components of the opposite conductivity type can be used to apply signals of the opposite polarity to the same bus. At turn-on, the circuit comprising Q4 - Q7 discharges node N25 rapidly to overcome the threshold voltage of Q2. <IMAGE>

Title: Video signal format for post-production
Inventor: GLASGOW PAUL ROBERT
IPC: H04N5/765
Filed: 1994-11-25
Abstract: For past-production purposes a real time video signal is converted into a "gateway" video signal whose format is 60 field/s at 1.25 or 1.2 times the real-time rate. The "gateway", video signal provides a number of advantageous possibilities, including: frame-locked transfer of material from real-time 24 frame/s and 25 frame/s film to the gateway format; frame-accurate post-production editing not requiring a 3232 relationship and retaining the gateway format; real-time post-production editing with a synchronised 3232 relationship between different sources and the product; and frame-locked transfer of material from the gateway format to real-time 24 frame/s or 25 frame/s film and 50 field/s video. <IMAGE>

Title: Tuning local oscillator frequency in PSK and OFDM digital broadcast.
Inventor: OHKUBO TADATOSHI
IPC: H04L27/26
Filed: 1997-02-07
Abstract: To control the oscillation frequency of a local oscillator 9, a digital broadcast receiver demodulates a phase-reference symbol contained in an orthogonal frequency-division multiplexed broadcast signal. The resulting frequency-domain data are modified by multiplication with complex conjugates of the known data encoded in the phase-reference signal, under different assumed frequency offsets between the frequency-domain data and known data. The results are converted to time-domain data 13, yielding one time series for each assumed frequency offset. One value is taken from each time series, these values are compared, and the oscillation frequency is adjusted according to the comparison results 15.

Title: Method of installing guttering and gutter runs for use therein
Inventor: DANIELS PATRICK IAIN
IPC: E04D13/064
Filed: 1997-04-28
Abstract: A method of fitting guttering with a predetermined drainage incline uses a length of base gutter which is fitted with its lower surface level. An insert 7 is present within the base gutter having a water carrying profile and fitted on its underside with spacer means 12-15 arranged to provide a uniform incline when lying on or attached to the supporting base gutter. Preferably the spacer means comprise support members located between the lower surface of the insert and the upper surface of the base gutter and the support members have an outer edge which matches the inner profile of the base gutter and the lower surface of the insert. The insert may be flat or downwardly convex. The support members are preferably fixed in position by adhesive and the space between the insert and the base gutter is filled with a rigid or semi-rigid polyurethane foam. The insert is held rigidly in position on the base gutter and the foam composition is injected into the space between in a manner that ensures both a correct uniform incline and also a watertight seal between the edge of the insert and the inner wall of the base channel. The insert and the base gutter are preferably fabricated from UPVC or a similar thermoplastic synthetic polymer.

Title: Suppressing unwanted amplitude modulations due to anti-stimulated Brillouin scattering modulation
Inventor: IMAI KEISUKE
IPC: H04B10/2537
Filed: 1997-06-20
Abstract: An optical transmitter comprises a light source 2 for outputting a carrier beam CB and an optical modulator 4 for modulating the carrier beam based on a main signal MS and sending out an optical signal OS into an optical fibre transmission line 6. To suppress stimulated Brillouin scattering (SBS) in the fibre 6 a circuit 10 frequency or phase modulates the carrier beam based on a low frequency signal LS from an oscillator 8. This broadens the bandwidth of the signal OS increasing the threshold at which SBS occurs. However such frequency/phase modulating causes unwanted amplitude modulations. These latter modulations are removed by way of a second circuit 14 which superposes an inverted signal IS, which is equal but of opposite phase to the low frequency signal LS, onto the main signal MS and supplies the resultant signal SS to the optical modulator 4. Thus SBS is suppressed without any loss of signal quality. Also disclosed is an embodiment using a variable gain optical amplifier in place of the optical modulator 4 and a reciever which acts to suppress the unwanted amplitude modulations.

Title: Half-bridge networks with loop prevention
Inventor: PASCOE DAVID JOHN
IPC: H04L45/18
Filed: 1997-12-01
Abstract: In order to enable utilisation of half-bridges 40 in networks in which a spanning tree algorithm is implemented, the priorities of the half-bridges are set such that generally the half-bridges select which of their ports should be blocked to break any communication loops which arise in preference to full bridges making the selection which may result in communication links via the backbone ports of the half-bridges being disabled. Further, a half-bridge is proposed in which more than one of its ports are available for configuring as the backbone port.
