Title: Magnetic recording and reproducing system for document signals
IPC: G09B5/06

Abstract: 1,143,268. Magnetic tape recording of document signals. SONY CORP. 3 Nov., 1966 [4 Nov., 1965], No. 49353/66. Heading G5R. A magnetic recording and reproducing system for document signals comprising a magnetic tape and means for moving a magnetic head along a magnetic track oblique with respect to the lengthwise direction of the tape is characterized in that an index signal for each track is magnetically recorded on the tape, and that means are provided for stopping the travel of the tape in accordance with the number of the index signal counting from a reference position. Recording and playback take place while the tape is stationary. As shown in Fig. 2, magnetic tape T is at rest on a guide G during recording or playback of a signal representing a film or a page of a book or the like; a recording head H is moved for this purpose along guide rods L by an endless belt V driven by a motor M3, and makes contact with the tape above an oblique groove gL in the guide G. A reference signal is recorded at an appropriate point by a fixed head QH and index signals, one for each track, are recorded on the opposite edge of the tape by a pair of fluxsensitive heads FRH1 and FRH2, preferably of multi-gap type. Movement of the tape in either direction is effected by reel motors M1, M2, but fine control of tape position is effected by motors M1<SP>1</SP>, M2<SP>1</SP>, which drive rollers RL1<SP>1</SP> RL2<SP>1</SP> respectively, engaged with rollers RL1, RL2 respectively, when appropriate, by plungers MPL1, MPL2, respectively. Controlling and monitoring.-The apparatus of Fig. 2 is represented by outline 4 in Fig. 1. During recording, the image of a document 1 is picked np by a unit 2, and the resulting signal passes through a transmission system 3 to the recording apparatus 4 under the control (not detailed) of a circuit 6. For playback and display of a particular document, a request signal RQ is applied to a comparator 11 forming part of circuit 6. A reference signal detecting circuit 9 detects the output of magnetic head QH and sets a counter 10 which counts the pulse output from an index signal detecting circuit 8 which detects the outputs from heads FRH1 and FRH2. The output of counter 10 is compared with request signal RQ in the comparator circuit 11, and the output of the latter controls the reel motors M1 and M2 through a processing circuit 12. When agreement is reached the tape is stopped. Part of the output of the index signal detecting circuit 8 is fed to a circuit 13 for finely controlling, by motors M1<SP>1</SP>, M2<SP>1</SP>, the position of the track to be scanned by head H. Thereafter, head motor M3 is driven under the control of circuit 6 and the reproduced signal is stored on a rotating magnetic sheet MS, and repeatedly reproduced therefrom at a display device 7 (e.g. a television receiver).

A device for locating faults on a transmission line comprises a trigger unit 1 connected to the protective relay circuits of the line, a control unit 2 connected thereto and controlling the number of pulses transmitted along the line, a synch.-pulse unit 4 connected to the control unit and arranged to operate a pulse generator 5 following and a dark trace tube 3 displaying transmitted and reflected pulses together with calibration markers, the tube 3 having a modulator receiving the output of the control unit 2. At the incidence of a fault on the transmission line, the protective relays cause the trigger unit 1 to produce a trigger pulse. This is fed to the record-duration control unit ) 2 which comprises two mono-stable circuits pulse output pulses add, producing a delayed pulse of length To, Figs. 2, 4 (not shown). This pulse is fed to the modulator of a dark trace tube 3 which produces a trace for time T o  During this time the control pulse causes the sync. generator 4 to produce n pulses which trigger n sweeps of the tube time base 7, n pulses from the pulse generator 5 which pulses are transmitted down the line and n sets of calibration markers. These markers and the transmitted and reflected pulses are fed to the vertical deflection plates of the dark trace tube which is of long persistence. The distance along the line to the fault can then be read directly. The trace may be removed by  heating the substrate film of the tube, e.g. by passing an electric current.

Abstract: 1,255,827. Speed adjustment of labelling machine. H. KRONSEDER. 14 Oct., 1969 [16 Oct., 1968], No. 50503/69. Heading B8F. The rate of throughput of articles in a labelling machine is controlled by monitoring devices 2, 12 which are sensitive to the accumulation of articles at the inlet and outlet regions of the machine, and which actuate an article blocking device 6 at the inlet region. Articles such as bottles or cans are fed by a conveyer 5 and worm 7 through a labelling device (not further disclosed) driven by an infinitely variable speed gear comprising double coned pulleys 9, 15, a belt 29 and motor 10. The effective diameter of pulley 15 is varied by a pneumatic cylinder 18. A rack 16 and gear-wheel 17, operable manually by lever 24, set the maximum speed ratio. When the labelling device is idling and the blocking device 6 is operable, a switch 2 senses any accumulation of articles at the inlet and actuates valve 1 so that a pressure cylinder 4 is rapidly evacuated through a pneumatic circuit to withdraw the blocking member 6. Simultaneously, the pressure cylinder 18 is slowly evacuated to alter the effective diameter of pulley 15 and increase the speed of the labelling device. If an output switch 12 senses article accumulation, the control valve 11 slowly activates pressure cylinder 4 through the pneumatic circuit to operate the blocking device 6, and rapidly activate pressure cylinder 18 to idle the labelling device. A manual switch 20 can be used to operate the blocking device 6 and speed control at any time; the automatic control provided by the monitoring devices 2, 12 can be shut off by a switch 22. An hydraulic or electrical control circuit may alternatively be employed.
