Filed: 1960-11-11
Abstract: 915,212. Time alarm signals. STANDARD TELEPHONES & CABLES Ltd. Nov. 11, 1960 [Nov. 17, 1959], No. 38876/60. Class 118. [Also in Group XXXIX] A telephone subscriber wishing to be called at a predetermined time may gain access to alarm equipment at the exchange which records the desired time as represented by dialled digits and also the subscriber's number, so that the call may be initiated in due course under time control. As shown for a PABX the alarm equipment is reached by the dialling of a particular number. The subscriber's number is identified and recorded on relays CR, and after receiving fresh dialling tone WT he dials four digits representing the time he wishes to be called, these being recorded on switches StZ, StE, MiZ, MiE. An acknowledgment tone QT may be sent, or the time may be repeated back acoustically from apparatus ZG. The contacts of the storage switches are connected to those of similar switches which are stepped from a clock, and when coincidence occurs a relay An operates and starts an alarm selector WW which is set under the control of the relays CR. The subscriber is called and upon reply receives from ZG a time announcement which may be followed if desired by a short message previously recorded by himself. If the subscriber is found engaged, the call may be repeated until it is successful, and the time announcement is then corrected. The subscriber may cancel the time record without releasing if he has misdialled, or he may recall the alarm equipment in order to cancel the alarm call. The alarm equipment may be located at another exchange, in which case the subscriber's number is transferred thereto in code form.

Title: Markers for telecommunicatios systems
IPC: H04Q3/42
Filed: 1975-09-23
Abstract: 1519213 Automatic exchange systems SOC ITALIANA TELECOMUNICAZIONI SIEMENS SpA 23 Sept 1975 [29 Oct 1974] 38924/75 Heading H4K A translator comprises a first memory which determines whether the number of digits supplied by a register relate to a valid translation and if so the memory supplies an address for accessing a second memory at a position corresponding to the first junction of a particular routing direction. The second memory output is used to determine whether this junction is free and if not the memory is caused to step to its next position and so on until a free junction is found. If the dialled digits correspond to a non-existent code or if there are no free junctions, as is determined by the second memory having stepped through all its positions which are associated with the first position, busy tone is reverted. As the second memory steps through its positions, alternative routes are taken into consideration. A register R applies with all the digits so far received to the translator each time it has recorded a digit but in general of course first digit has no effect. If say, the register supplies the code 373, the device TR accesses the memory M at a cell corresponding to the initial digit 3. The cell contains a number e.g. 21 which is fed back to TR and added to the second digit i.e. 21 + 7 = 28. This serves as the address for a next cell which may contain the number e.g. 81. Again this number is fed back and now added to the third digit i.e. 81 + 3 = 84. The latter cell contains a digital address code for accessing a second memory M2. If the code is in fact for a non-existent number, decoder D recognizes it as such and causes busy tone to be reverted (the examination involves a logical assessment of the digital word using AND and OR gates). The second memory seizes a circuit PI which tests the junction whose identity is supplied by M2. If it is free, the junction is seized and the register advised to out pulse thereover. If it is busy, PI causes scanner SC to step the memory M2 to the next cell associated with the requested route. This repeats until an idle junction is found or all junctions test busy. The memories may be of the ROM type being preprogrammed as re-programmable.

Abstract: 1477183 Optical playback of magnetic recordings EASTMAN KODAK CO 12 Sept 1974 [12 Sept 1973] 39849/74 Heading G5R A magnetic record 5, Fig. 1, is reproduced by a method in which a beam of polarized light is directed towards the record 5, the plane of polarization of the beam being angularly oscillated by a modulator 3 either before or after the beam impinges on the record 5, and in which a signal corresponding to the beam polarization modulation due to the record 5 is separated from a combined signal a, Pig. 2, including said signal and a signal corresponding to the modulation due to modulator 3, the separation being achieved by comparing the widths #t 2  of pulses formed from even-numbered halfwaves of the combined signal a with the widths #t 1  of pulses formed from oddnumbered positive halfwaves of the combined signal, each pulse having a width equal to that of the positive halfwave from which it is formed. A magnetic tape 5 is driven so that its magnetization vector has a component along the axis of the beam from laser 1, polarizer 2 and modulator 3 which modulates the polarization plane at a frequency N, e.g. 100 KHz. The Faraday effect adds a rotation #, dependent on the signal on tape 5, to the polarization plane of the light beam transmitted through the tape via analyser 7 to a silicon photodiode 8 the output of which passes via amplifier 10 to a filter 11  which separates the signal components at frequencies N and 2N, these components being amplified by frequency-selective amplifiers 12, 12<SP>1</SP> respectively and summed by adder 13 to give signal a in Fig. 2 from which comparator 14 yields signal b, Fig. 2, which is acted on by flip-flop 15 and a circuit 16, formed by NAND gates 17, 17<SP>1</SP> and NOT gates 18, 18<SP>1</SP>, to produce pulse trains e, f, Fig. 2, with pulse widths #t 1 , #t 2  corresponding to the lengths of the odd and even positive half waves of signal a, a differential amplifier 19 therefore giving signal g Fig. 2, which is integrated at 20 to give the playback signal since (#t 1 -#t 2 ) is proportional to #, i.e. to the recorded signal. Modulator 3 may comprise a quarter-wave plate 3<SP>11</SP> and a deuterated KDP crystal 31 energized by an oscillator 31<SP>11</SP>, or this crystal may be replaced by an electrically birefringent material or a piezoelectric material energized by an acoustical wave, or a material exhibiting the Faraday effect in an alternating magnetic field, or a mechanically oscillated polarizer. The magnetic Kerr effect on a reflected beam may be utilized instead of the Faraday effect on a transmitted beam.
