Title: Improvements in or relating to control systems for the automatic actuation of control surfaces of moving craft
Inventor: FEARNSIDE KENNETH
IPC: G05D1/00
Filed: 1958-08-15
Abstract: 869,095. Automatic steering control systems. SMITH & SONS (ENGLAND) Ltd., S. Aug. 17, 1959 [Aug. 15, 1958], No. 26383/58. Class 38 (4). A servomotor operating a control surface of a craft is or is not, according to conditions, controlled automatically by signals acting in opposition to follow-up signals dependent on movement of the control surface, and the difference signals are effective through an integrator to operate a warning device when the integrator output exceeds a predetermined value. As shown, signals from a gyro compass 12 on an aircraft control through a mixer 13, amplifier 14, electromechanical transducer 15, electromagnetic clutch 16 and hydraulic actuators 8, 17, sections 9, 18 of a control surface so as to maintain, automatically, a desired course. Follow-up signals from a potentiometer 19 operated with the control surface are fed back to mixer 13. Signals from amplifier 14 are also applied to an integrator 24, the output of which operates an indicator 25 and, if it exceeds a predetermined value indicating a fault, operates an alarm 26 and a relay 23. The latter then deenergizes clutch 16 and energizes a clutch 31 so that automatic steering is disabled and a manual controller 32 engaged with hydraulic actuators 8, 17. The contacts of relay 23 may be locked manually so that, on operation of a changeover switch 30, a clutch 7 is energized to render a second gyro-compass 3 effective to control hydraulic actuators 8, 17 through a duplicate control system. This second control system is provided with an indicator 21, an alarm 22, and also controls relay 23 so that either control system may be engaged by switch 30 when both control systems are free of faults. Before the contacts of relay 23 are locked a fault in the control system not in use is also effective to disengage automatic control.

Title: Process of producing artificial threads and like articles from viscose
IPC: D01F2/10
Filed: 1955-09-15
Abstract: Regenerated cellulose filaments and like products consisting entirely of skin are made by extruding viscose containing 4-8 per cent of cellulose, 4-8 per cent of caustic soda, 30-50 per cent of carbon disulphide (based on the weight of the cellulose) and 0.2-4 per cent, preferably 0.5-2 per cent (based on the weight of the cellulose) of polyoxyalkylene glycol ethers of castor oil or of hydrogenated castor oil or of mixtures thereof, into an aqueous coagulating bath containing 10-25 per cent of sodium sulphate, 3-15 per cent of zinc sulphate (or at least 3 per cent of zinc sulphate and, in addition thereto, a water-soluble sulphate of a heavy metal other than zinc, the concentration of the sulphate of the metal other than zinc being such as to bring the total heavy metal sulphate content of the coagulating bath to not over 15 per cent, calculated as zinc sulphate) and sulphuric acid, the sulphuric acid content of the coagulating bath exceeding the slubbing point but being below the concentration at which neutralization of the caustic soda in the viscose is so rapid as to produce filaments consisting of skin and core.  The ethers may contain 20-200 or more, preferably 30-100, ethylene oxide units per molecule of castor oil or hydrogenated castor oil.  The ether may be added at any stage in the production of the viscose, and the salt test of the viscose at the time of spinning is preferably 6 or higher, particularly 8 or higher.  In an example, a viscose containing 7 per cent of cellulose, 6 per cent of caustic soda, 41 per cent of carbon disulphide (based on cellulose) and 2 per cent of a polyoxyethylene glycol ether of castor oil (containing about 40 ethylene oxide units per molecule of castor oil) is spun at a sodium chloride salt test of 9 into a coagulating bath which is at about 60 DEG  C. and contains 7.3 per cent of sulphuric acid, 8 per cent of zinc sulphate and 18 per cent of sodium sulphate.  The yarn is thereafter conducted through a bath of water at about 95 DEG  C. in which it is stretched about 82 per cent.  Small proportions of the ethers may also be added to the spinning bath.

Title: Proton precession magnetometer
IPC: G01R33/24
Filed: 1960-07-29
Abstract: 901,052. Magnetic testing apparatus. CANADA, MINISTER OF MINES & TECHNICAL SURVEYS. July 29, 1960 [Nov. 30, 1959], No. 26524/60. Class 37. [Also in Group XL (c)] A proton precession magnetometer in which there is a sample of matter of which some of the protons are capable of precessing in a magnetic field, whose intensity is to be measured, so as to produce a detectable signal whose frequency is the frequency of precession, includes a variable frequency oscillator whose frequency is controlled by a control signal, a counter responsive to the output of the variable frequency oscillator and which produces one cycle of output signal for each N cycles of oscillator output signal, and means for comparing the signal whose frequency is the frequency of precession with the output signal of the counter so as to produce the control signal thereby to cause the frequency of the output of the variable frequency oscillator to become N times the frequency of precession. A proton sample S, e.g. water; is surrounded by a coil A for polarizing the protons and also detecting the alternating current induced by the precession of the protons about thefield to be measured on removal of the polarizing field, the latter being carried out by a programmer B which when the polarizing current through the coil A has been reduced to zero allows the signal produced by the protons to be passed to amplifier C. A variable frequency oscillator D oscillates at frequencies which are N times the expected frequencies of proton precession and its output is fed to a counter E which gives one cycle of output for each N cycles of input. The full-wave phasesensitive detector F mixes the separate signals received from the amplifier C and the counter E to obtain a D.C. output which is fed through a low-pass filter G and stabilizing network H to a D.C. amplifier J, the output of this amplifier being fed back through feedback loop R to control the frequency of oscillator D. The effect of the feedback is to force the oscillator D to synchronize at a frequency of oscillation which is N times that of the proton precession signal. The output frequency of the oscillator D is measured by a counter P, the operation of which is controlled by the programmer B, a reset pulse from which at the beginning of each measuring interval causes the counter P to begin a new count. In order that a direct reading of the magnetic field strength may be obtained rather than a reading of the oscillator output frequency, a time-interval generator L controlled by a crystal oscillator K opens a gate M between the counter P and the oscillator D for a predetermined length of time so as to have the effect of multiplying the oscillator frequency by a constant in order to give a direct reading of magnetic field strength in appropriate units.
