Title: Improvements in or relating to wired broadcasting systems
Inventor: GABRIEL RALPH PARTON
IPC: H04N7/10
Filed: 1958-02-04
Abstract: 823,506. Distributing music &c. COMMUNICATIONS PATENTS Ltd. Feb. 4, 1958, No. 3618/58. Drawings to Specification. Class 40 (4). In a wired broadcasting system, particularly one for television signals, a plurality of signals are distributed, in respect of the same programme material, in different portions of the frequency spectrum so as to enable the use by subscribers of either special receivers specific to the system or normal broadcast receivers. In a first embodiment a television picture signal modulated on a carrier wave of about 4.9 Mc/s. is distributed over a coaxial cable to which the special receivers may be coupled in any of the usual ways. To enable the use of broadcast receivers also, the picture signal is also distributed on a carrier wave of 45 Mc/s. To this end, the cable is equipped at intervals with low-pass filters which prevent the passage of the 45 Mc/s. sideband(s), thus providing portions of the cable which are electrically isolated from one another for those frequencies. For each such portion a frequency converter and amplifier receives the modulated 4.9 Mc/s. carrier from the cable and supplies to that portion of the cable, preferably at its centre, a correspondingly picture-modulated carrier of 45 Mc/s. The sound signals are dealt with in a similar manner. In a second embodiment two two-wire lines are provided, over the first of which the picturemodulated 4.9 Mc/s. carrier is distributed and to which the special receivers are coupled. The second two-curve line is divided into electrically-isolated portions, as far as the modulated 45 Mc/s. carrier is concerned, by low-pass filters, each such portion being supplied with modulated 45 mc/s. carrier by a frequency converter and signal amplifier taking its input from the first two-wire line. The sound signals may be distributed on the first line as audio-frequency signals, a modulator being provided in association with each frequency converter and signal amplifier to provide to the second line a correspondingly modulated carrier wave of 41.5 Mc/s., corresponding to the sound channel frequency of a broadcast receiver tuned to the 45 Mc/s. picture carrier wave.

Title: Intrusion detection system
IPC: G01S13/56
Filed: 1973-01-24
Abstract: 1388353 Intruder alarm systems AEROSPACE RESEARCH Inc 24 Jan 1973 [10 Feb 1972] 3621/73 Heading G4N [Also in Division H4] A Doppler intrusion alarm for detecting the presence of a moving target in the presence of interference comprises: means for producing, from a received signal, first and second signals which include Doppler signals representative of the moving target; means 32, 34, 36 for producing, from the first signal B, sampling pulses E which occur regularly due to a moving target, but randomly due to interference; means 24 for sampling the second signal A with the pulses E; means 26 for integrating the output from the sampler 24 to produce a signal which varies unidirectionally due to the moving target, but randomly due to the interference; a threshold 28 actuated to produce an output if the integrator output exceeds a predetermined level; and an alarm 30 responsive to the output from the threshold 28. The sampling pulses are produced by squaring the first signal in a limiter 32, differentiating the output at 34 and then amplifying the positive pulses. When low frequency Doppler signals with superimposed noise are present, the sampling pulses are inhibited by a bias derived from a filter 37. In a modification, Fig. 4 (not shown), both positive and negative pulses from the differentiator are amplified and are fed to separate sample and hold circuits (24, 42) so that the second signal is sampled at twice the rate. With signal due to a moving target the samples are always taken at the same point in a cycle so that the integrated output from 26 increases unidirectionally until it exceeds the threshold of 28 and operates alarm 30. Interference signals produce an output from integrator 26 which fluctuates about zero and does not reach the threshold.

Abstract: 539,242. Electric synchronous movements. TOLNAI, G. K., and AKTIEBOLAGET G. AREHNS MEKANISKA VERKSTAD. March 1, 1940, No. 3900. Convention date, March 1, 1939. [Class 40 (iii)] [Also in Group XXXVIII] In an arrangement for conveying angular or rotary movement from one shaft to another, each shaft carries a disc 2, 13 formed over one half with contact sectors 5 connected to progressively increasing voltages, these sectors being wiped over by pairs of synchronously driven brushes 10 which are interconnected as shown through relays 32, 33 and 37, 38. If the disc 2 is angularly displaced in relation to the disc 13, as indicated in Fig. 3, the interconnected brushes will periodically engage sectors at different potentials, viz. between points A, B of the disc 2, and a number of impulses will be transmitted to the relays 32, 33 and 37, 38. The latter operates a relay 34 to withdraw a holding pawl 35 and allow a shaft 21 to be driven by a motor 23, while the relay 32, 33 which is polarized connects up one or other of two relays 28, 29 to couple the shaft 21 to a shaft 19 for forward or reverse drive to bring the disc 13 into synchronism with the disc 2. If the discs 2, 13 are both rotating continuously, the arrangement will serve to correct lack of synchronism. The differential gearing shown in Fig. 5 may be employed to convert the intermittent correcting movements into continuous movement. The rotation of the shaft 19 is conveyed through epicyclic gearing 58, 39, 40 to a shaft 42, which, through gearing 43, 44 displaces a roller 48 from the centre of a friction disc 49, the rotation of which is thus transmitted through gearing 50, 41 to rotate the planet wheel 39 around the wheels 58, 40. This arrangement also speeds up the synchronizing movements.
