Abstract: 1452488 Pulse shaping circuits INTERNATIONAL BUSINESS MACHINES CORP 19 Dec 1973 [26 Jan 1973] 58932/73 Heading H3T In a circuit for processing signals read out by a transducer from a magnetic record medium, the signals including positive and negative pulses with peaks corresponding to opposite sense transitions in magnetization on the medium, a pulse shaper 18 including a delay line 22 narrows the pulses and portions of the signals from the pulse shaper 18 below a certain amplitude are removed by a circuit 20. An output from a magnetic head (14, Fig. 1, not shown) which acts as a differentiator at low frequencies is amplified at (16) and is applied as a data read out signals 2A (Fig. 2, not shown) to a delay line 22 which modifies the input signal by the delay and reflected delay to provide a desired narrow pulse output 2B from the output of emitter followers 40, 42 connected to the outputs of a differential amplifier 28, 30. A variable resistor 26 adjusts the gain to trim the sides of the pulse and aid in the narrowing action. A variable resistance network 32 adjusts the gain to bring the signal within a range that will enable centre slicing or clipping of the narrowed pulse signal. This output 2B includes the positive and negative peaks and low amplitude h.f. noise and is fed to a centre slicing amplifier 20 that includes non- linear diode matrices 44, 46 which remove signal portions below a certain amplitude so as to leave emphasized narrow peaks at 2C and also limit noise. This data signal 2C is separated into two channels 68, 74, 80 and 82, 84, 80 for processing positive and negative data. A positive peak exceeding a predetermined threshold cause a bi-stable multivibrator 68 to generate a positive pulse (2E) at 70 which operates a bistable flip-flop 74 when a delay clock (2D) occurs from a clock drive 76 which is coupled to an adjustable delay 78. When bi-stable 74 is operated it generates a positive pulse which resets the bi-stable 68 and also passes via OR gate 80 to the output (21). The next clock trigger (2D) from clock 76 resets the bi-stable 74. The other channel 82, 84, 80 operates in a similar manner to detect data pulses of negative polarity, also representing binary "ones" in NRZI coding.

Sleeve 1 may be of stainless steel, the heater may be a pair of resistors R16, R17 in parallel, and the thermally responsive elements may be a pair of thermistors, the resistors and thermistors being encapsulated within the sleeve. As shown in Fig. 2, the thermistors and resistors R12, VR2, R11 form a bridge circuit which is connected between the heater power line 23 and line 21. The bridge unbalance is detected by amplifier Al, the output of which controls transistors T 2 , T 1  which control the potential of line 23 to maintain a constant temperature difference between the thermistors TH1, TH2. The current supplied to the heater to maintain the constant temperature difference is sensed by differential amplifier A2 connected across resistor R7 in the line 23 and the output of A2 operates a relay RL1 via transistor T 4  according to whether the heater current is above or below a predetermined value. Transistor T3 may be mounted on the probe and may be replaced by two transistors in cascade.

Abstract: 677,355. Electric measurements. GENERAL ELECTRIC CO., Ltd., and MATTHEWS, A. Dec. 8, 1950 [Dec. 15, 1949; Aug. 8, 1950], Nos. 32234/49 and 19740/50. Class 37. [Also in Group XXXVIII] In apparatus wherein the mutual inductance between the primary 1, 2, and secondary windings 3, 4, Fig. 4, of a transformer is altered in dependence on a variable being measured, e.g. the thickness of a non-magnetic coating on magnetic material, a small displacement or a variable such as pressure, torque, &c., readily translatable into a displacement, the magnitude of the variable is indicated by a dynamometer type meter, Fig. 3, having a magnetic core 17, its field winding 19 being fed from the same source 24 as the transformer primary and its moving coil 18 series connected with the transformer secondary 3, 4. The meter has substantially no mechanical restoring torque acting on the moving coil. It also has an auxiliary coil 20 series connected with the moving coil 18 and is so constructed that the voltage induced in the moving coil 18 by the field winding 19 varies linearly with the angular position of the coil 18, being zero at the position shown of half scale deflection. If the transformer secondary voltage varies linearly with the variable being measured, it is shown in the Specification that the meter deflection also varies linearly with the variable but is also dependent on the frequency of the transformer primary current. For zero adjustment of the meter a variable resistor is shunted across the auxiliary winding 20, Fig. 5 (not shown). To make the device sensitive also to the sense of the variable, i.e. to measure both +ve and - ve variations on a centre zero scale, the auxiliary winding is disconnected, Fig. 6 (not shown), and by removing the resistive component of the transformer mutual reactances the deflection may be made independent of frequency. This is effected, e.g. as shown in Fig. 7, by connecting the transformer primary 1, 2 in series with a resistor-capacitor combination 28, 29, across the A.C. supply in parallel with the field winding 19. Another arrangement is disclosed in Fig. 8 (not shown). The above noted circuit arrangements are described as used with a measuring head, Fig. 1, in which linear displacements of a spindle 7 move the magnetic core element 6 to vary the air-gaps 10, 11 differentially, whereby, the output from the transformer secondary coils 2, 3 connected in opposition give an output varying in magnitude and phase sense according to displacement of the block 6 from a central position. The circuit arrangements disclosed may also be used with a known form of head, Fig. 2 (not shown), for measuring the thickness of a non-magnetic coating on a magnetic base.
