Patent GB-805919-A (GB)
Abstract: 805,919. Automatic speed control systems. IGRANIC ELECTRIC Ltd. March 7, 1955 [March 19, 1954], No. 6605/55. Class 38 (4). The speed of a motor 10 is controlled by comparing the output of a tachometer 16 driven by it with a voltage representing the desired speed taken from a potentiometer 14, and feeding the error signal to magnetic amplifiers 18 and 26. The signal applied to magnetic amplifier 18 controls the current in winding 44 of a two-phase induction motor 20 having windings 38 and 44, so that the displacement of the rotor 53 and hence of the slider 22a of potentiometer 22 is proportional to the time integral of the error signal. To the potential between points 22a and 54a, which is thus proportional to the time integral of error, is added the voltage induced in this circuit by transformer 24, which voltage is proportional to the time differential of error since the current in its primary 24a is proportional to the error; hence the signal applied to terminals 35, 36 and 57, 58 of amplifier 26 are proportional to the error, and to the sum of terms proportional to the time integral and differential of error, respectively. The output of magnetic amplifier 26 is fed to the field winding 60 of generator 61 supplying the motor 10 and driven by motor 63.

Patent GB-2074152-A (GB)
Title: Coating method
IPC: H05K1/05
Filed: 1981-03-09
Abstract: A method of coating a material comprising blending the coating substance with a binder, applying the blend onto a surface and drying to form a sheet, removing the sheet from the surface and fixing the sheet to the material by fixing in, for example, printed circuits used in microelectronics, a mild steel substrate is coated with a glass which is devitrified to a glass ceramic. Relative to conventional electrically insulating coatings of porcelain enamel, the glass ceramic has a relatively high refractoriness and low mobility of alkali ions, resulting in a relatively low rate of change of the electrical characteristics of the coating with increase of temperature. A lithia- based glass may be blended with an organic binder including a silk-screen binding medium and a slurry is formed. The slurry is then applied under controlled conditions to a backing paper and dried to form a sheet. The sheet when dry is removed from the backing paper and fixed to the substrate by firing. By controlled cooling the glass devitrifies to the glass ceramic.
