Abstract: 1483381 Automatic voltage control  INTERNATIONAL BUSINESS MACHINES CORP 29 Oct 1974 [17 Dec 1973] 46686/74 Addition to 1483382 Heading G3R [Also in Division H2] In a voltage reducer of the type in which a plurality of capacitors 12 ... 15 are successively both charged and discharged through a load 11 under control of transistor switching devices 17 ... 20, the circuit is arranged to have two modes of operation based on different sequences of conduction of transistor switching devices 17 ... 20 so as to provide two different reduction ratios and having a first retroactive voltage regulator 30, 31 operable in both modes and a further voltage regulator 34 ... 41 arranged to change the mode when the first regulator 30, 31 reaches lower and upper limits of its operation. As described, the voltage reducer has a first mode in which transistors 17, 20 are conductive during a first period and 18, 19 during a second period, giving 1/4V across the load 11 formed by a LSI computer. In a second mode, transistors 17, 18, 20 are conductive during a first period and 19 during the second period giving 1/3V across the load 11. The transistors 17 ... 20 are controlled from an oscillator 25 via a binary trigger 26. The trigger pulses for transistor 18 are supplied via two AND gates 39, 40 an OR gate 41 and an analogue gate 32. The voltage across load 11 is compared by an amplifier 30 with a Zener reference 31, the error voltage controlling the gate 32 so as to determine the magnitude or duration of conduction of transistor 18 and hence regulate the voltage across load 11. If the input voltage from source 10 falls excessively, transistor 18 is likely to reach saturation so that the voltage across it, when compared at 35 with a reference (not shown) provides an error which operates a AND gate 37 and a flip-flop 38 to change the mode of operation. Similarly, if the input voltage rises excessively, transistor 18 will tend to over-dissipate so that comparator 34 will return the operation to the original mode.

Abstract: 476,071. Light - current relays. BUTLER, Ltd., H., and JUPP, R. H. Sept. 11, 1936, Nos. 24788 and 33908. [Class 38 (v)] A light - current relay comprises a movable member such as a coil a responsive to small currents and carrying a contactmember c, a pair of fixed contacts d co-operatmg with the contact-member c for closing in succession a pair of circuits adapted to be supplied with current from a common source, e.g. a battery e, a resistance f in one of the circuits, and means, e.g. terminals g in the other circuit for receiving, or connection to, a lamp or other indicator h, the arrangement being such that under the action of a small current the contact-member c first engages the right-hand contact d to close the circuit containing the resistance f, whereupon a larger current traverses the coil and causes the contact-member c to engage both contacts d and close the indicator circuit. The invention is particularly applicable to gas detectors for use in mines, the coil a, which is mounted in the field of a permanent magnet, being connected to terminals b, connected to any device which, in the presence of the gas to be detected, causes a small current to flow. The contact-member c is resilient, and in common with the contacts d may be made of magnetic material to reinforce the contact pressure. A reversing switch k may be connected between the battery e and the circuits, in order that the current through the coil may be reversed when it is desired to separate the contacts. Alternatively the contacts may be separated by means of a cam arranged to act on the movable contact-member c. An additional pair of terminals l may be provided for operating a distant indicator m supplied with current from an independent source connected to terminals n.

Title: Tachometer System

Abstract: 1,152,806. Measuring angular speed electrically. WESTINGHOUSE ELECTRIC CORP. Oct.23, 1967 [Nov.14, 1966], No.48019/67. Heading G1N. In a tachometer system in which an A. C. signal is generated whose amplitude is indicative of the speed to be measured, the reference level (zero) of the signal is changed to a level dependant on the amplitude of the signal. The A.C. components of the signal are then removed to leave a D. C. signal whose level is indicative of the speed. The output from the secondary winding 16, Fig.1, of a two phase tachogenerator 12, whose primary winding 14 is energized by a sinusoidal signal E 1  shifted in phase by 90 degrees by capacitor 62, is fed to the primary winding 39 of transformer 32. Two secondary windings 36, 38, producing two sinusoidal voltages E 2 , E 3 , see also Fig.2 (not shown), having a phase difference of 180 degrees, are connected, one via capacitor 44, in opposition, to a pair of switching transistors 46, 48 normally biased in their off states. The transistors 46, 48 are -switched into their conducting states once per cycle of signal E 1 . During this period, capacitor 44 is charged to the voltage across winding 36, arranged to be the peak amplitude of the signal, so that, during the non- conducting states of the transistors the voltage at junction 42 from winding 36 is increased by the charge on the capacitor 44, i.e. its reference level is raised to a level equal to the peak amplitude of the signal. This signal is then combined with that appearing on winding 38 to remove the A.C. component of the signal and fed to a high input impedance buffer amplifier 28 to produce a high level D.C. signal whose amplitude is indicative of the speed to be measured. The transistors 46, 48 are switched to their conducting states by pulses E 4  from a transistor 52 produced when it becomes conductive. The base emitter circuit of this transistor is so connected via Zener diode 58 and an RC differentiating circuit 56 to the energizing voltage E 1  that the transistor 52 is rendered conductive momentarily at the beginning of each cycle of the voltage E 1 . By virtue of the phase shift produced by capacitor 62 these pulses occur 90 degrees after the beginning of a cycle of the voltage E 2  i.e. at a point of maximum amplitude.

Abstract: 1373521 Adaptive equalizers ROCKWELL INTERNATIONAL CORP 18 Oct 1971 48422/71 Heading H4R In an adaptive transversal equalizer successive samples of an input signal 30 are fed into a set of storage devices 26 via a commutator 100. A commutator 200 feeds each of the stored samples, once each band period of the input signal, to a multiplier 24 where they are each multiplied by a respective one of the factors g-m to gn and the products accumulated, in 40, to provide the equalizer output. The factors g-m to gn are up dated, to cater for changes in the impulse response of the transmission system, by feeding the sign of the input signal samples Sgn. Xitm to a shift register 31 and deriving from the output of the equalizer, in 44, an error signal by comparison of the product of the system impulse response l 0  and the detected digit di with the actual equalizer output yi. The error signal sign, Sgn. Yi, is mod-2 added to the outputs from the shift register 31 stages to provide incrementing signals for the factor counters g-m to gn, effectively cross correlating the error signal with the input signal so that the factors are adjusted to provide the desired impulse response of the overall system. The system impulse response l 0  which is proportional to the mean of the product of the signal yi and the detected digit signal di, can be a stored constant value or can be continuously updated, e.g. by incrementing a counter storing the value of l 0  in a direction determined by the sign of the equalizer output error relative the sign of the detected output digit, Fig. 3. Alternatively the factor l 0  used to determine the nominal equalizer output may be fixed and a "learn l 0 " device 42 used to provide a reference to a gain control circuit on the equalizer input to provide a standard output level, Fig. 4. Fig. 4 also includes a different method of determining the nominal equalizer output yig by addition of a series of previous digital decisions di  o  multiplied by stored response values l 0  to ln 0 . A further alternative, Fig. 6 (not shown) can be used where the error signal magnitude as well as sign is used in updating the multipliers in the transversal equalizer, the mod 2 adders 31a of Fig. 2 being replaced by multipliers Fig. 7 (not shown).
