Title: Telecommunication system
IPC: H04Q3/52
Filed: 1972-10-06
Abstract: 1404780 Automatic exchange systems INTERNATIONAL STANDARD ELECTRIC CORP 6 Oct 1972 [8 Oct 1971] 46113/72 Heading H4K An automatic exchange system includes an array of cascaded switching matrices, a shift register per matrix arranged to store the busy/ free states of the crosspoints of that matrix and a marker arranged to interrogate selected shift registers, to select a useable path through the array and to control the crosspoints associated with that p th, the arrangement being such that the shift registers associated with matrices in the path are updated. As described the matrices are of the type described in Specification 1,287,374 and comprise MOS field-effect transistor crosspoints, the substrate capacitance of which is sufficient to maintain the operation state of that crosspoint for short periods. The shift registers also comprise field effect transistor stages, and have one binary stage per crosspoint. The binary bit in each stage normally supplies maintaining potential to the corresponding crosspoint and also functions as a busy/free store. Without interfering with the states of the crosspoints of a selected matrix the contents of the associated shift register can while the matrix has an inhibit signal applied to it be cycled through a marker for a path search operation. If it is required to operate or release a crosspoint of that matrix changing the relevant bit of the shift register content will following removal of the inhibit signal and after a delay due to the crosspoint capacitance cause the crosspoint to make the desired change. As shown the network comprises three switching stages Ta, Tb and Tc for connecting subscribers Ta 0 to Ta 63 to local junctors J001 to J301 and outgoing/incoming junctors J07 to J37, and an auxiliary stage Td for connecting the junctors to tone sources TN0 to TN3. The inputs and outputs of the shift registers (not shown) associated with the matrices of a stage are combined as at Ba and Sa for stage Ta it being possible to select the individual registers by inhibit/enable inputs EaO to Ea3. These latter inputs for the last two stages are combined as the fourth stage matrices are always associated with the adjacent third stage matrices. To effect a route search, a subscriber termination and a junctor termination are marked. There is one possible route through the network for each matrix of the second stage and each route is associated with a particular crosspoint in the first and third stage matrices. The marker includes means to compare the states of these crosspoints for each possible route until a free route is found.

Title: Multiplex communication system
IPC: H04L27/00
Filed: 1974-11-04
Abstract: 1450350 Mulitplex communication RAYTHEON CO 4 Nov 1974 [3 Dec 1973] 47636/74 Heading H4M At the transmitter of a multiplex communication system a first signal 36 created by modulation of a carrier (e.g. by data from telephone channels 26) but having a spectrum with substantially no carrier component, is mixed with a second signal 46 consisting of a modulated carrier and having a spectrum which does contain a carrier component, to provide the signal to be transmitted. The bandwidth of the modulating signal 44 (e.g. multiplexed service data) for the second signal is very much less than the bandwidth of the first signal. At the receiver the mixed signal 124, Fig. 2, is inversely modulated (at 72) with demodulated signal information representing the first signal, to produce the second. The carrier from this second signal is then filtered out, (74) and this carrier applied to demodulating arrangements (76, 78) which also receive the mixed signal to provide the demodulated information representing the first signal, which is fed back to the inverse modulator.  The first signal (36) represents multiplexed telephone channel data, the channels being sampled in time division (at 28) and fed as delta modulation (in individual time slots) to a quadrature phase shift key modulator 32 supplied with a 70 MHz carrier 34. The carrier is eliminated from the output spectrum of this modulator, which provides the first signal 36. The second signal 46 represents multiplexed service data 48 for the telephone system, which is sampled in time division and fed as delta modulation 44 to modulate an X band oscillator 42 (of frequency near 11 GHz). The modulated X band frequency providing the second signal is fed to a mixer 38 where it is combined with the first signal and thereafter transmitted. The mixed signal detected by the receiver 60 is fed via a delay 70 (Fig. 2) to an inverse modulator 72, wherein it is applied to phase and quadrature demodulators 94, 96, which receive phase and quadrature demodulated versions of the first signal on lines 116, 118, and the demodulator outputs are combined to provide on line 110 the second signal. This passes to a tracking filter 74 wherein the X band carrier is separated and passed via line 114 to in phase quadrature detectors 76, 78, which receive the recovered mixed signals (on line 62), at their other inputs. The detector outputs, after filtering, provide in phase and quadrature versions of the first signal. These are fed back to the inverse modulator and also supplied to a demultiplexer 88 from which the original telephone signals are recovered. The second signal modulating signals are derived on line 112 from the tracking filter and applied to a demultiplexer 90, from which the service data is recovered.

Title: Smoke detector
IPC: G01N21/53
Filed: 1977-11-16
Abstract: An alarm device (K) is actuated by an integrator (T) only if a photocell (C) receives a plurality of successive light pulses, reflected by smoke. In the disconnected mode, a light source (LED) is fed by a pulse generator (P) with low frequency. A first light pulse reflected by smoke occurring triggers via the photocell (C) a flip-flop (F), the output signal of which closes a switch (S1) in order to reduce the distance from the next pulse emitted by the pulse generator (P). Thus, if smoke persists, the number of pulses which the integrator (T) requires to set off the alarm is received in a shorter time. In another embodiment, the pulse frequency is increased by the first light pulse reflected by the smoke for the duration of a predetermined number of pulses or for the duration of a predetermined period of time. In both embodiments, the time required for the alarm to be set off is thus reduced, without increasing the power consumption of the detector device in the disconnected mode and without reducing the service life of the pulsating light source. <IMAGE>
