Abstract: 1,258,112. Transistor logic circuits. GENERAL INSTRUMENT CORP. 14 Feb., 1969 [15 March, 1968], No. 8264/69. Heading H3T. In, for example, a 4-phase logic system comprising basically F.E.T.'s Q1, Q3, Qa operating on phases # 3  and # 4  and F.E.T.'s Q1a, Q2a, Q2 operating on # 1  and # 2 , one logic stage Q1, Q3, Qa feeds over a line 20 a switch circuit such an invertor Q4, Q5; and erroneous signals on line 20 due to clock pulse edges of the one stage being fed through interelectrode capacitances are compensated by the injection of clock pulses of opposite polarity, derived from # 2  and fed through C1. The F.E.T.'s Q1 and Q3 in the first stage 10 of the 4-phase system receive # 3  and # 4 , and the data input F.E.T. Qa has F.E.T.'s Qb to Qn in series to constitute a NAND ate; F.E.T.'s Qa to Qn and a similar arrangement of F.E.T.'s Qa<SP>1</SP> to Qn<SP>1</SP> in parallel therewith form a NOR input. A similar stage 14 includes Q1a, Q3a receiving # 1  and # 2 , and an input F.E.T. Q2 receiving the stage 10 output 16; a further NAND input at Q2a, and NOR inputs at Q6 etc. are provided. The gate capacitance of Q2 of stage 14 and of Q5 of invertor 12 is charged via Q 1 during the # 3  period, and discharged or not during the second part of the 94 period according to the inputs L1-Ln<SP>1</SP>; similarly the output of stage 14 is charged by Q1 a  during the # 1  period and discharged or not during second part of # 2  period according to -the inputs (not all shown). The F.E.T. Q4 of the inverter charges the gate capacitance of Q6 of the output stage 14-during # 4  period, and this is discharged or not at the end of # 4  according to the voltage level at Q5 gate. The gate voltages of Q2 and Q6 are thus opposite. Erroneous operation of Q5 may follow, however, from the storing at its.gate of positive steps (27, 29, Fig. 3, not shown) arising from the positive-going edges 26, 28 of # 3  and # 4  transmitted through the source-gate capacity of Q1 and the drain-gate capacity of Q3: a negative level at Q5 gate may thus become a zero level. This is offset by introducing through a capacity voltage divider C1, C2 the # 2  negative-going edge 36. A ratio of C1 to C2 of 1 to 8, for example, ensures that a desired zero-level at Q5 gate, due to discharge of its capacitance through Q3 etc. according to the inputs L1 to Ln<SP>1</SP>, is not made negative by more than a permissible amount (35, Fig. 4d, not shown). The inverter operates as a NOR gate when inputs 1N2 to 1N-N are applied to F.E.T.'s Q12, Q13, Q n .

The phase of the output signal of a photo-electric head K reading an optical grating varies in accordance with position of a machine tool member and is compared at U with the phase of a fixed reference signal from a potentiometer L. The difference signal controls the frequency of a nominal 1 Mc/s. generator G whose output is passed to the head K either via division circuits I and P (¸ by 100) for an inches readout or via W and P (¸ by 254) for a metric readout. A reference generator passes an accurate 1 Me/s. through similar division circuits to a potentiometer L. Actually circuits P and Q provide four signals each to the head K and potentiometer L. The output of frequency generators G and H are counted in respective counters A and B, A when full gating the output of B to display tubes F, which displays the number of cycles added to, or subtracted from the output of generator G to alter the phase of the signal to the head K to compensate for the change of phase introduced by the change in position of the machine tool member.

As shown the tongue 60 has members 62, 64 which define forwardly converging exterior lateral surfaces which co-operate with forwardly converging interior lateral surfaces in the socket 72 of the other dolly to prevent relative lateral or vertical movement between the coupled dollies. The dolly has a fifth-wheel coupling comprising a plate 38 (Fig. 5) longitudinally adjustable relative to and securable to chassis side members 30, 32. The plate 38 supports a fifth wheel 48 to which a king-pin of the loadcarrying body can be secured by a retainer 52. The coupled dollies may be mounted to the load-carrying body in tandem fashion either by way of kingpins engaging with the fifth wheels of the dollies (Fig. 6, not shown) or by a pneumatically actuable coupling (Fig. 7, not shown) locating with the eye of the forward of the two dollies. In each of these arrangements the dollies form the rearward running gear of the body. In the former arrangement a third dolly can additionally be provided. This dolly, like the second dolly of the arrangement of Fig. 7, has no kingpin secured to its fifth wheel. The coupled dollies may also form the forward running gear of the body (Fig. 8, not shown).

The oscillator may be used as a nerve locator/stimulator and consists of a blocking oscillator VT 1  producing a square wave output such as 30 pulses/sec with push button PB 1  pressed and a lower frequency such as 1 pulse/2 sec with PB 2  pressed. As capacitor C 1  has to charge on pressing PB 1  the output pulse occurs after a delay time required for C 1  to charge sufficiently to make VT 1  conduct. However as C 2  is charged by R 2  when PB 2  is pressed transistor VT 1  conducts immediately and an output pulse is obtained. Diode D 1  conducts for positive going pulses from W 3  which are limited by the zener diode D 2 . However on negative going pulses from W 3 , D 1  is reverse biased, D 2  is forward biased and most of the output voltage is across gas discharge lamp LP 1  which lights. In an alternative output circuit (Fig. 2, not shown), a further zener diode (D 3 ) may be connected in circuit between the diode D, and the potetiometer R 5  by opening a switch (S 2 ) so that the output voltage is reduced to the difference between the breakdown voltages of the zener diodes (D 3 ) and D 2 . The resistor R 6  stabilises the firing point of VT 1  and compensates for variation in Cl. The oscillator may be mounted in a plastics container marked with suitable indicia and apertured to mount the lamp LP 1  and to take a connectable probe or electrode lead plug. Electrodes for use with the oscillator may be in the form of needle electrodes or probes.
