Title: Telecommunication Switching System
IPC: H04M15/08
Filed: 1966-12-09
Abstract: 1,152,616. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 9 Dec., 1966 [13 Dec., 1965]. No. 55216/66. Heading H4K. In an exchange in which calls are set up with the assistance of a register RE, adaptor circuits AS are associated with the line circuits of certain subscribers, such adaptors having a store ZO, Fig. 2 (not shown), for recording the calling and called numbers, the latter in permanent form. When one of these subscribers is called, a comparison circuit OK conditions the register to receive the calling number, preferably in VF form, which in response to a signal from the adaptor is obtained from an identifier IK in the same exchange or from the register at the originating exchange. The calling number is then transferred to the store ZO. The adaptor also serves to supply ringing current and tone. If the called subscriber finds the call is a malicious one, he dials the digit 1, which causes the adaptor to initiate a call to an operator's position at the same or another exchange, while holding the original connection, and to deliver the recorded numbers thereto. The arrangement may be used also for the benefit of traders receiving orders by telephone, in which case the calling number is sent from the adaptor to an indicator at the called party's station. In either case VF transmission from the store ZO is employed.

Abstract: 1,172,505. Information storage arrangements. ELEKTRONISCHE RECHENMASCHINEN WISSENSCHAFTLICHER INDUSTRIEBETRIEB KARL - MARX - STADT. 14 Dec., 1966, No. 56015/66. Headings G4C and G5R. In an information store for digital or analogue data the storage medium comprising dispersed particles, or at least one tape or filament, is carried by a fluid vehicle medium and is moved successively past respective means for the recording and read-out of information. In a first embodiment (Fig. 1) a liquid 18 is pumped around a closed loop comprising a tube 2, a calming chamber 19 and a reservoir 4 by a pump 3, the arrangement being such as to maintain laminar flow at least in the region 12. Particles 5, which may be influenced reversibly or otherwise by magnetic or electric fields or by radiation, are injected into the liquid at the same velocity as the liquid through tubes 6 whereby lines 5 of particles are formed in the liquid. Information may be recorded by a transducer or radiation source 10 and read-out by a transducer or other known means 11, a feed-back amplifier being shown at 13. Data may be erased by a high-frequency field. A magnetic or electric field may be maintained axially along the region 12 to prevent turning of the particles. A magnet or other means may be provided at 8 to direct the particles into guide channels 6b through the reservoir 4. The particles may be coated and the liquid may have substances dissolved therein so as to obtain suitable densities. Crystalline liquids or colloids may be used as vehicle liquids. The particles may be of filament shape. The tube 2 may be wholly or only partly filled with liquid. The particles may float on the liquid surface or may be submerged. The tube 2 may be of capillary dimensions with a single path 9 therethrough or may be larger with a plurality of paths. Reference is made to the use of a gas in place of the liquid and to films of liquids covering the surfaces only of the tube 2. In place of separate particles these may be formed into bands or tapes 17 which may be endless and circulate in closed loops as illustrated in Figs. 2 and 3 (not shown). Fig. 4 (not shown), illustrates a suitable transducer with hollow cylindrical polepieces.

Abstract: 1422456 Rolling mills; joining strip WEAN UNITED Inc 6 Dec 1973 [16 March 1973] 56496/73 Headings B3M and B3A In a continuously operating tandem strip rolling mill, the trailing end of a coil 22 being rolled is joined to the leading end of a subsequent coil 20 in a spot welding or stitching apparatus 38, and the work rolls of the stands 10 are opened as the join passes through the stands. During a joining operation, the mill is slowed down, and a strip accumulator allows the stands to continue working while the joining takes place. The mill is operated at its normal speed when the join has passed through the mill. A flying shear 58 performs a cut on either side of the join, the first strip length being wound on coil 64, while the new strip length is directed to a coil 62. The strip join is in the form of a simple overlap between the adjacent strip lengths, and the shear 58 crops on either side of the join. The stands of the mill may be opened sequentially as the join passes, using sensors 46, 49, or may be opened simultaneously. Tensiometers 48 detect and control the strip tension between adjacent stands. When tension is established between the final stand and the appropriate coiler 64 or 62 after a joining and shearing operation, the speed of the mill is increased to its normal level.

Abstract: 1374293 Dropout compensation SONY CORP 7 Dec 1971 [11 Dec 1970] 56886/71 Heading H4F In a video signal reproducing system provided with dropout compensation, compensation is prevented when dropout occurs in proximity to a vertical synchronizing signal. Video signals reproduced from tape 4 by magnetic heads 8, 9 are passed alternately by switch 25 to limiter 26 and demodulator 27. The signals also pass through a dropout detection circuit 40 including an envelope detector 42 and waveform shaper 43. The output from circuit 40 is passed through gate 55 to control switch 32 to pass the demodulated video signal either directly or through a delay line 34 with a delay of one horizontal line period to output 36, in known manner. Mounted on tape guide drums 10, 11 is a pulse generator 45 producing two pulses per rotation of the drums. The pulses produced are passed through a variable delay circuit 53 to a monostable vibrator 54. The delay is adjusted so that gate signal S thus produced starts just before the vertical synchronizing signal. The gate signal closes gate 55 just before the vertical synchronizing signal is due and holds it closed. until it has passed. The gate signal may be derived from a control signal or an independent gate signal on the tape, or from an oscillator.
