Abstract: 1497059 Transistor switching circuits ENGINS MATRA 16 Dec 1974 [14 Dec 1973] 54299/74 Heading H3T A fail-safe circuit has two saturable cores T01,  T02 which are taken into saturation in one sense when an input signal X1, X2 is present by control means connected to a first winding B1, which control means here is a transistor T1 gated on and off by a clock H. A continuous, non-gated, signal 2 is applied to a second winding B3 to saturate the cores in the other sense. Output voltage signals appearing on a third winding are applied to an output circuit R5, C3, T3 so arranged that an output signal of the circuit U, T will be above a predetermined level only when there is no component failure and when correct input signals are applied. The capacitor C3 of the integrator R5, C3 has four connecting leads to enable the circuit to confirm it has not failed. In action, when Z is positive, say, an output is said to be obtained at T and when it is negative an output is obtained at U. By suitably winding and connecting the various windings B1, B3 on the two cores the presence of the clock signal H is checked.

Title: Improvements in or relating to Magnetic Store Read-Out Arrangements.
IPC: G11B20/14
Filed: 1966-12-09
Abstract: 1,150,309. Frequency and phase modulation recording. SIEMENS A.G. 9 Dec., 1966 [10 Dec., 1965], No. 55238/66. Heading G4C. Frequency or phase modulated information in a magnetic layer store is scanned to produce a reading signal which is evaluated independently of a reference pulse pattern recorded in a separate track, the evaluated signal being employed to form output signal pulses whose positions in time are determined by the reference pulse pattern, the time interval between successive voltage peaks of the reading signal being compared with a measuring time that is up to 70% of the reference pulse interval, and an evaluator pulse shorter than the pulse interval being formed if the distance in time between successive voltage peaks is larger than the measuring time. Binary data recorded on a magnetic tape, plate or drum store in frequency modulated form, i.e. one and two changes of magnetization for 1 and 0 respectively, when read is passed via a band-limiting reading amplifier (not shown), transformer 1 and symmetrical differentiator 2 to a bi-stable trigger 3. The trigger 3 is switched on and off when its input rises above a positive threshold and falls below a negative threshold respectively. The trigger outputs are differentiated and then mixed in an OR gate 4. Each pulse from gate 4 returns a ramp generator 5 to a low value from which it then rises. If the ramp reaches a high value before the next input pulse from gate 4 arrives, the arrival of this pulse produces a pulse from threshold device 6. This pulse sets a trigger 7 which is then reset by the next bit clock pulse from a timing track on the store. This clock pulse also causes a trigger 8 to take up the state trigger 7 had just before the clock pulse arrived. The output of trigger 8 thus represents the data bits 1 and 0 as the presence and absence of constant duration synchronized pulses. The thresholds of the trigger 3 may be automatically adjusted in accordance with the peak voltages encountered, or the reading amplifier may be a control amplifier. It is mentioned that a similar system can be used with phase modulation recording. Input to the store may be from an electronic further store.

It is desirable that the transform lens 90 have an f number no greater than 1À2. Whilst this can be achieved with a single lens it is desirable to use a three lens system 74 in which lenses 56', 88 have reducing f numbers, the final lens 90, being the transform lens.

The information stored in the modulator may be an array of bits, and the hologram formed to have a density of 3600 bits per m.m. square. The tape or microfiche may comprise a matrix of holograms. Where the modulator is reflective, 112 (Fig. 8), the modulator is angled to the incident beam 100 so that the reflected object beam 114 follows a different path. If desired the beam splitter may be used both to separate the illuminating and reference beams, as well as illuminating and reflected object beams. Read out may be on a projection screen or using T.V. cameras or other photo-electric devices. The micro-fiches may be part of a computer data processing system.
