Title: Improvements in and relating to electrical phase discriminators
Inventor: WEAVER JOHN JAMES LAWRENCE
IPC: H03D13/00
Filed: 1956-02-10
Abstract: 850,646. Phase discriminators. ENGLISH ELECTRIC CO. Ltd. Feb. 8, 1957 [Feb. 10, 1956; June 4, 1956], Nos. 4242/56 and 17178/56. Class 40(5). [Also in Group XXXV] In a phase discriminator of the type in which the vector sum and difference of two frequency inputs at 11, 12 are rectified at 15, so that the difference of the D.C. outputs across a resistor 16 equals approximately the lesser amplitude of the inputs multiplied by the cosine of the phase difference, the output is biased by a D.C. voltage proportional to the amplitude of the weaker input 12 so that zero output occurs when the phase difference has a particular value and sense dependent on the bias. As shown the bias (positive or negative) is obtained from a rectifier bridge 19 and is adjustable by tappings on transformer secondary 18d to vary the phase difference corresponding to zero output. Further, a rectifier 50 and bias 51 of value proportional to the amplitude of input 11 may be arranged as shown so that, eyen when the input 12 across resistor 17 considerably exceeds one half the input at 11, the backing off bias across capacitor 23 does not exceed that of variable bias 51, due to rectifier 50 conducting, and the same phase difference for zero output still applies. If the input 11 is of constant voltage the bias 51 may be a Zener diode or discharge tube voltage stabilizer. The discriminator may be applied to stabilizing power factor of an electric furnace.

Title: Improvements in or relating to the production of yarns or staple fibre by the viscoseprocess
IPC: D01D5/22
Filed: 1949-02-28
Abstract: Viscose is extruded into a coagulating bath consisting of dilute sulphuric acid containing aluminium sulphate, and sufficient alkali-metal sulphate to convert the sulphuric acid into an alkali-metal bisulphate, and the filaments obtained are passed through a hot aqueous bath while being stretched by at least 50 per cent of their original length, and are then washed, and finally dried while in untensioned state.  Alternatively, the filaments may be dried under tension, re-wetted, and then re-dried without tension. The filaments may be cut to form staple fibre and the drying may be effected after cutting.  The coagulating bath may contain 30-120 grams per litre of aluminium sulphate and the viscose employed may have a Hottenroth salt value of at least 14.  The filaments, fibres, and yarns obtained have a strong set curl and low swelling characteristics.  In an example, viscose, containing 7 per cent of cellulose and 7 per cent of caustic soda and having a Hottenroth salt value of 15, is extruded into a coagulating bath containing 110 grams of sulphuric acid, 250 grams of sodium sulphate, and 100 grams of aluminium sulphate per litre.  The temperature of the bath is about 50 DEG  C.  The yarn of filaments obtained is led from the coagulating bath into a second bath consisting of 10 grams of sulphuric acid per litre at 85 DEG  C.  The yarn is subjected to a stretching of 90 per cent during its passage through this bath, the length of which is sufficient to ensure complete regeneration of the cellulose.  The yarn is collected, washed, and skeined.  It is then desulphurized, bleached, oiled, and then dried without tension. Specifications 260,681, 313,921, [both in Class 2 (ii)], 467,500, 481,565 and 570,159 are referred to.
