Abstract: 864,258. Control of A.C. motors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 19, 1957 [July 20, 1956], No. 22547/56. Class 38 (3). [Also in Group XXXV] In a closed loop system for an induction motor, rotor resistance is adjusted by a coil F in accordance with the difference between the output of a tachometer generator TG and a reference voltage and during dynamic braking the D.C. energization applied to stator WMS is controlled in accordance with the voltage drop across coil F. The field of generator G which is controlled by the voltage drop across coil F and through an amplidyne A1 has an energization voltage E 3 , E 4  applied to a separate field winding, the field of which is greater than the maximum field which can be produced by the winding in the amplidyne output, in order that the stator field is not reversed. The variable control field is limited by a resistor R, a part of which may be shunted by a rectifier to permit field forcing.

Title: Improvements in or relating to demodulators for frequency modulated waves
IPC: H03D3/00
Filed: 1964-06-01
Abstract: 1,059,393. Frequency demodulators. G. BATTAIL, and P. BROSSARD. June 1, 1964 [June 5, 1963], No. 22558/64. Addition to 960,807. Heading H3A. The analyser used in the frequency demodulator of the parent Specification to obtain an estimate of the modulation signal is modified whereby the output of each tuned circuit is applied via phase shift means to a synchronized detector and thence to an amplitude comparator to both of which reference signals are applied from the tuned circuit channel currently receiving the highest signal. Assume the tuned circuit 301 is in receipt of the highest signal, as a result gated amplifier 3111 is open and the received signal is applied to an amplifier 3010 which supplies it as reference signal to the synchronous detectors 3021-3024 in each channel and also to synchronous detector 3020. This latter detector to which the received signal is also applied directly develops a D.C. output signal which is used as a reference by amplitude comparators 3051-3054. Assume also that the signal received by circuit 301 subsequently decreases and that received by circuit 302 increases; this latter signal is applied to one input of gated amplifier 3112 and via amplifier 3012 to synchronizing detector 3022. The detector provides a D.C. output signal which is a function of the amplitude of the component of its input signal, which is in phase with the reference signal supplied via circuit 301, this output is applied to one input of amplitude comparator 3052. When the value of this increasing signal exceeds that of the decreasing reference signal the comparator provides an output which (a) triggers a monostable circuit which provides an inhibit signal for gate 3222, (b) provides an input for a differentiating amplifier which supplies via gate 3221 a return to zero output signal to comparator 3051, (c) a signal to open gated amplifier 3112 which now provides the reference signal to the detectors and comparators of all channels and (d) a signal to weighting addition network 3200 which delivers a voltage proportional to the rank member of the channel receiving the highest signal as described in the parent case. The damping on the tuned circuits and the phase shifts introduced by the phase shift networks are such that a signal having a frequency midway between the resonant frequencies of two adjacent tuned circuits produces output signals from the respective phase-shift networks which are in phase.

Abstract: 1472712 Heat-treatment furnaces for continuous strips VSES NI I PROEKT-KONSTRUKTOR INST METALLURGICHEMASHINOSTROENIA (SLAUYAN FILIAL) 23 May 1975 22643/75 Heading F4B In apparatus for heat-treating metal strip, the strip, after being heated in a furnace, is stored in an insulated soaking chamber 19 having an inlet 30 and an outlet 31 for the strip, heating elements 16a, a pair of parallel support drums 21, 22 for the strip, with driving means for rotating them in opposite directions and a guide roll 28, 29 on each side of the chamber, each movable on a carriage up and down sideguides 24, 25 for guiding the strip on to the drums. Each drum has gripping jaws pivoted at the outer ends and adapted to be opened and closed by external drives. In the closed position they grip the strip against a flat surface 43 of the drum. In another form, Fig. 12 each carriage has a pivoted arm 60 carrying a further guide roll 63, the arm having an extension which in one end position of the carriage engages with a drive for tilting the arm towards the adjacent drum. The operation of the drums is cyclic, starting for example with a two-layer reel on drum 21 as shown in Fig. 12. The strip 3 is in one continuous length between inlet 30 and outlet 31 being gripped in the middle by jaws of drum 21 and the greater part of the length being wrapped around drum 21. The other drum 22 is turned so that the guide rolls 28 and 63 can position the strip flat against the gripping surface of the drum, where it is gripped by closing the jaws. Drum 22 then rotates anticlockwise, Fig. 13, so as to wind on to itself the incoming strip and one of the layers of strip from drum 21. The other layer of strip from drum 21 leaves the chamber via exit 31. When drum 21 is empty, Fig. 14, the jaws open, releasing the out-going length of strip and the drum is turned to enable it to grip the incoming length, a new reel them being formed on drum 21 in the same way. The soaking chamber is followed by cooling, shearing and reeling units.

Title: Improvements in or relating to adding/subtracting circuits for digital electronic computers
Inventor: KILBURN TOM
IPC: G06F7/50
Filed: 1958-07-18
Abstract: 897,425. Digital electric-calculating apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 13, 1959 [July 18, 1958], No. 23107/58. Class 106 (1). A circuit for adding or subtracting two binary numbers in the parallel mode comprises a carry signal line connecting the several stages, each stage including a device which is rendered conductive if carry through the stage is possible, whereby carry through successive stages may be effected with substantially no delay. Fig. 3 shows the nth stage of a binary adding circuit, to which the digits xn, yn are applied. If xnyn transistor T1 is triggered by a negative signal applied to its base. If a carry pulse from the preceding stage arrives it passes through T1 without delay because T1 is already conducting. If xn = yn = 1 transistor T2 generates a carry pulse which is applied to the suceeding stage. Fig. 4 shows a 3-stage adder with a carry line 11 and an inverse carry line 12. T15 passes carry pulses if x 1 y 1  and T16 propagates carry pulses if x 1  = y 1  = 1. Similarly, T19 passes inverse carry pulses on line 12 if x 1 y 1  and T20 propagates inverse carry pulses if x 1  = y 1  = 0. As described, a carry "1 " is positive with respect to a carry " 0," but an input "1 " is negative with respect to an input " 0." A reversed logic is therefore applied to producing the sum outputs on terminals S 1  and S 2 . Thus T17 and T18 produce an output at S 1  if there is carry from the first stage and x 1 y 1 , while T21 and T18 produce an output at S 1  if there is inverse carry and x 1  = y 1 .

Title: Method for the regeneration of spent pickle liquor
IPC: C01G49/14
Filed: 1965-06-01
Abstract: Spent pickle liquor containing FeSO4 and diluted H2SO4 is regenerated by adding crystalline FeSO4.H2O to the liquor to form a slurry containing 20 to 50% weight FeSO4 and maintaining the slurry between its freezing point and 130 DEG  F. for a sufficient time for the formation of FeSO4.7H2O which is then removed. The H2SO4 concentration in the liquor although increased by this procedure may further be increased by adding conc., e.g. 66 DEG  B<\>ae, H2SO4 whereby FeSO4.H2O is precipitated an this is removed.  The FeSO4.7H2O may be heated to 100 DEG  to 200 DEG  C. to form FeSO4.H2O and water, the heating being under such pressure to maintain the water in liquid form, e.g. 60-100 p.s.i.g. and the monohydrate is separated from the water, at least some may be recycled.  The FeSO4.H2O precipitated may be recycled.  The filtrates may be recycled. The liquor after removal of FeSO4.&H2O is preferably maintained at 27-49 DEG  C. during the addition of conc. H2SO4 and the resultant liquor generally has less than 5% FeSO4 and more than 40% H2SO4.  FeSO4.H2O formed from the heptahydrate may be used to form H2SO4 by roasting to give SO2 which is converte to SO3 thence to H2SO4.
