Title: Improvements in and relating to deviation compensators
IPC: G01C19/36
Filed: 1950-06-06
Abstract: 685,480. Electric correspondence control systems. BRITISH THOMSON-HOUSTON CO., Ltd. June 6, 1950 [June 7, 1949], No. 14113/50. Class 40 (i). The signals from a compass-controlled directional gyroscope are automatically adjusted by corrective signals of the correct magnitude and phase derived from a preadjusted compensator. A conventional compass-controlled directional gyro system comprises a gyro 8 (Fig. 1) controlled by a flux-gate type compass 9 through a selsyn detector 10 and phase-sensitive amplifier 13, and includes a remote transmitter 12 and indicator 11. The angular position of the gyro is indicated by a shaft 19 geared to the gimbal 15 and connected to the rotor 27 of the selsyn detector 10 whose stator winding 28 receives the second harmonic output of the flux-gate compass 9. Error signals are thus produced in the detector rotor winding 31 which are amplified and rectified at 13 to energize field windings 34 of a torque motor to precess the gyro. The gyro shaft 19 is also coupled to the rotor 36 of the transmitter 12, thereby causing the rotor 42 and pointer 43 of the indicator 11 to repeat the angular position of the gyro. To the above is added a compensator 44 comprising a stator winding 45 (Fig. 2) similar to winding 23 of the flux-gate compass 9 and energized by the same source 39 as the remote transmitter stator winding 38. Thus the angular position of a Z-shaped magnetic rotor 47 will correspond with that of the transmitter rotor 36, and the gyro 8. Two annular stacks of laminations 48 are disposed around the rotor 47, and between the rotor and the laminations is a series of oppositely wound coils, 50, 51, all connected in series, and in series with the output of the detector rotor coil 31. The coils are mounted in pairs on brackets 63 slidable on shafts 64 adjustable by screws 65, so that for each angular position of the gyro 8 and rotor 47 a voltage is added to the output of the detector 10 adjustable in phase and magnitude to compensate for known errors. In a modification the rotor 47 is driven directly by the gyro shaft 19, obviating the need for the stator winding 45. The compensator may be applied to other types of selsyn systems for maintaining angular positional relationships.

Title: Improvements in or relating to the treatment of yarns or threads
IPC: D06M23/10
Filed: 1926-06-04
Abstract: 264,382. British Celanese Ltd., Addy, C. W., Billing, J., and Halkyard, H. June 4, 1926. Yarns, treating with liquids.-In a process for sizing and dressing yarns, applicable to yarns composed of or containing natural fibres or artificial filaments or fibres, the yarn packages, wound on bobbins, cops, pirns, tubes, spools or the like, are immersed in a solution of sizing or dressing agent in a volatile solvent and then dried by evaporation of the solvent and wound continuously on to hanking frames, bobbins, or the like. The drying may be effected during winding of the yarn on the final carrier or the original sized package may be partly dried before winding. As solvents, water, benzene, toluene, xylene may be used, and solvents that volatilize with difficulty, such as paraffin oil, may be added. As sizing or dressing agents, mixtures of resins or metallic resinates or naphthenates with non- drying oils, fats, waxes and fatty acids such as are described in Specifications 244,947 and 244,979, [both in Class 121, Starch &c.]. are suitable and the treatment may be effected in vacuum. Penetration may be aided by pressure or by vacuum and pressure alternately. The evaporation of the solvent may be effected at ordinary room temperature or by passing the yarn over a hot plate, and air currents may be used.

[Classes 39 (i) and 40 (iii)] An oscillation generator comprises a hollow electric resonator which is caused to oscillate simultaneously in a fundamental and a harmonic mode by an electron beam directed across it, and means are provided for tuning the harmonic frequency which do not affect the fundamental. The means may be a lumped capacity, but in the forms shown, a wave-guide is employed with a critical frequency above that of the fundamental. In Fig. 1, a coaxial resonator 1 is excited by a velocity-modulated beam 2, 3. The fundamental is tuned by a piston 4, while the harmonic is tuned by wave-guides 5, 6 containing " filter pistons " of the kind shown in Specification 586,122. A joint 11 ensures that the guides are in the correct nodal relationship to the electron beam. In Fig. 2, a resonator 13 is excited by a beam 14 passing through a gap formed by wings 15. The guide 17 and tuning piston 18 tune the harmonic. In Fig. 3, the tubular resonator 19 is tuned by pistons 24, 25 connected by a wave-guide 20 which will not pass the fundamental, piston 24 tuning the fundamental and piston 25 the harmonic. In another form, a toroidal resonator is tuned by a wave-guide joined to it at one side with its axis perpendicular to that of the resonator. Specification 537,490 also is referred to.

Abstract: 766,363. Electric indicating systems. SMITH & SONS (ENGLAND), Ltd., S. May 11, 1955 [May 14, 1954], No. 14252/54. Class 40(1). The D.C. output of a thermocouple 1 is fed to an amplifier 10 through a resistor 13, the output of the amplifier being fed back through the resistor 13 to maintain the input constant, the output current being measured by a moving coil meter 5. Thus any change in temperaure produces corresponding variations in thermocouple output and amplifier output, and is indicated on the meter 5. Ambient temperature variations are compensated by a bimetallic strip 16 in the meter 5 which automatically adjusts the meter zero. A transformer 8 couples the input and output of the amplifier to introduce into the input circuit a rate of change of output voltage to overcome hunting.
