Title: Influencing meteorological phenomena
Inventor: YING-CHEUNG CHEE
IPC: A01G15/00
Filed: 1986-02-25
Abstract: A lightweight container of rigid plastics material comprises two united hemispheres 10, 12, each having six apertures 14. The container is covered by a layer of brittle and water soluble gelatine which forms closure webs 16 over the apertures. The container holds lightweight polystyrene beads which are coated with a mixture of silver iodide, solid carbon dioxide and common salt in a volume ratio of 3:2:1. To diminish a typhoon, a load of charged containers is released by an aeroplane whilst encircling the periphery of the typhoon. The closure webs 16 are opened by fracture under the shock of discharge, by solution by atmosphere moisture or solution into water onto which they may fall. After opening, the coated beads are dispersed and are effective in diminishing the typhoon. On account of their light weight, the beads remain airborne or float on a water surface for a prolonged period during which they remain active. <IMAGE>

Patent GB-2189969-A (GB)
Title: Code tracking circuits for spread-spectrum receivers
Inventor: TRINDER JULIAN RICHARD
IPC: H04B1/707
Filed: 1986-04-30
Abstract: A code tracking circuit operates by cross-correlation of a received wideband signal against a locally generated tracking code sequence. When the local sequence is identical with the embedded sequence in the received signal, the correlation characteristic is the same as the code autocorrelation function. A local code sequence generator 40 includes delay elements 42, 44 to provide 'early', 'prompt' and 'late' phases of the local code sequence which are phase multiplexed by a phase sequencer 28 and switch 26C to provide the tracking code sequence. The cross- correlation is effected by a multiplier 14, a narrowband filter 16 and an AM demodulator (including an AGC amplifier 18 and a linear detector 20), and the cross-correlation output is applied via switches 26A and 26B respectively to a lock comparator 50 and to a loop integrator circuit including an amplifier 30. The three multiplexed samples ('early', 'prompt' and 'late') from the detector 20 are then used to provide a lock indication by the lock comparator and to control the code sequence generator 40 via the integrator amplifier 30 and a voltage controlled oscillator 38. <IMAGE>

Title: Controlling gain in speech-controlled telephones
Inventor: LANGSTED SVEN
IPC: H04M9/08
Filed: 1986-11-07
Abstract: A speech-controlled telephone comprises a transmit path having a microphone coupled to a communication channel output via a transmit amplifier (2) and a transmit attenuator (4) and a receive path having a loudspeaker coupled to a communication channel input via a receive amplifier (6) and a receive attenuator (7). The speech signal levels in each path are detected by detectors (8, 9) and the gains in each path are controlled via a differential amplifier (10) so that attenuation is decreased in a path with speech signals and increased in the other path. The total gain is kept below a maximum level, which maximum level is reduced when a comparator (12) detects high-level signals in each path indicating a howl-round condition. <IMAGE>

Title: Optronic speed measurement
Inventor: MOTZKO FRIEDRICH
IPC: G01S17/58
Filed: 1987-11-27
Abstract: The device, which measures optronically the mean relative speed of two objects, uses light pulses from a laser 10. A multi-gate device 16 (in detail in Fig. 2) samples returning pulses and produces a low frequency sinusoidal output whose consecutive nodes correspond to the object passing through consecutive range gates. By measuring the time between zero crossings of this, a measure is given of the relative speed.

Title: Spectrum analysis in a communications system
Inventor: KING KENNETH DAVID
IPC: G01R23/16
Filed: 1989-04-11
Abstract: In a communications ESM system wherein an incoming signal is converted to an intermediate frequency and then Fourier analysed (as in Fig. 2 not shown), the frequency spectrum (Fig. 3) for energy values above a detection threshold is analysed to determine whether observed peaks are merely side bands of other peaks, e.g. P and Q relative to A in Fig. 3, or whether they are independent signals, e.g signals (ii) and (iii). In use, the largest peak (A) is identified (20) and the frequency difference (v) between edge values (B,C) on either side of a below-threshold point is determined (22, 24, 26, 30) and is compared (32) with a pre-set value. If the difference (V) is greater than the pre-set value a new signal is assumed to start at edge value C. If it is not, a decision as regards whether a new signal is starting is made depending on the ratio of the peaks P:Q (as determined at 36, 38, 40). <IMAGE>
