Filed: 1974-04-25
Abstract: 1468579 Automatic control ROTARY CLUB GENEVE SUD 25 April 1974 [25 April 1973] 18162/74 Heading G3N [Also in Division G4] A coded control signal, given by a human operator, having successive long or short elements is transduced to electric signals and the elements compared with a reference signal having a value intermediate of the extreme values of the signals whereby the short or long elements are identified and subsequently decoded for controlling the operation of an electrically controllable apparatus. A shown, short or long control impulses i are selectively provided at a shaping circuit 9 from a micro-switch 7 or a microphone 4 responsive to whistling or fricatives through a high-pass amplifier 8. The output is of the shaping circuit is fed to miller integrators 10, 11 which are reset at the beginning of an element by a signal Z. Integrator 10 integrates the duration of the element of the signal and retains it during the interval between elements, whereas integrator 11 integrates the duration of the space between elements. The number of elements is counted by a ring counter 13 which controls the transfer of the contents d of the integrator 10, through field-effect switches S1-S6 into capacitive memory units 12a-12f To determine whether the level held in a memory unit is a dot or a dash, the output is passed to a comparator 14a-14f in which it is compared with a reference r common to all comparators which has been held in a store 15 from an n or <SP>1</SP>/ n  logic circuit 16 which compares all but the first element with the value of the first element. The states of comparators 14 and counter 13 are decoded by a diode matrix 17 to select the wanted letter, or operating function, before its performance by an electric typewriter, (not shown), through control circuits 22. A lag between decoding and operation is provided by a comparator 18 responsive to the output of integrator 11 and the reference r which controls a printing circuit 19. All circuits are set to zero by a circuit 21. A comparator 20 can be provided to cause the matrix 17 to order a space after a set time interval between code signals. The matrix 17 through switching equipment 24 can determine whether the electric typewriter or external operating circuits, such as TV, radio, lights &c. are controlled by decoded signals.

Title: Improved process for the recovery of chemical products from viscose rayon spinning baths
IPC: D01F13/02
Filed: 1945-07-18
Abstract: Chemical products, from viscose rayon spinning baths containing sulphuric acid, sodium sulphate and less than 2 per cent. of zinc sulphate in solution, are recovered by evaporating water from said bath while maintaining the temperature above 32 DEG C. so as to precipitate crystals of anhydrous sodium sulphate associated with complex salts containing sodium, zinc and hydrogen sulphates, separating the crystals from the mother liquor at a temperature above 32 DEG C. and then submitting the crystals to countercurrent lixiviation with an aqueous sodium sulphate solution at a temperature above 32 DEG C., the amount of water in said solution being insufficient to dissolve all the sodium sulphate contained in the crystals but sufficient to decompose the complex salts and dissolve substantially all the sulphuric acid and zinc sulphate contained therein.  The lixiviation may be effected in two stages, in the first of which sodium sulphate collected as drippings from freshly spun threads may be used, and a hot saturated solution of pure sodium sulphate for the last washing stage.  The acid mother liquor removed from the crystals and the washing liquor containing sulphuric acid and zinc sulphate may be returned to the spinning bath, while the crystals of sodium sulphate may be dried.  Specifications 298,639, [Class 1 (ii)], 384,726, U.S.A. Specifications 1,863,172, 2,374,004 and German Specification 356,103 are referred to.

[Class 110 (iii).] A machine driven by a wind engine, e.g. a dynamo or pump, is regulated so that the maximum power available at any speed may be utilized, or the wind engine may be regulated to a constant speed. A dynamo-electric machine geared to the wind engine and generating a voltage proportional to its speed is connected in series with a second dynamo driven by the wind at a speed proportional to its velocity and the difference between the two voltages effects the regulation by any known means. The second dynamo may be replaced by any device such as a magneto-anemometer giving a voltage proportional to the wind velocity or by a source of constant voltage, if the speed of the wind engine is to be constant. The Figure shows a wind engine M coupled to a generator G supplying a battery B and load C and the generator output is controlled by a solenoid operated resistance regulator R in the circuit of the field winding I. A dynamo D geared to the wind engine M is in series opposition with a dynamo D<1> driven by a second wind engine M<1> at a speed proportional to the wind velocity and with the solenoid S of the regulator. The voltage difference may vary the throw or port opening of a pump or compressor.
