Drawings to Specification. Heading H2A. A system of pole-changing by pole-amplitude modulation which is especially useful for wide ratios, employs chording to eliminate the unwanted pole-number. In order to obtain the wide ratio, the pole-amplitude modulation wave has three complete cycles or a multiple of three complete cycles in the machine perimeter. This means that the unmodulated pole-number cannot be a multiple of three (otherwise the same phase would be repeatedly modulated by the modulation wave). The unwanted polenumber is eliminated by using a coil-pitch equal to an even number of pole-pitches of that polenumber. The higher pole-number, providing the shortest pole-pitch is the more easily eliminated. The use of a modulation wave having three cycles or a multiple thereof, means that the modulating effect is symmetrical for all three phase-windings provided the unmodulated pole-number is not a multiple of three. Thus the effect produced is of an overall modulation of the three-phase winding as a whole. Specifications 900,600 and 926,101 are referred to.

Abstract: 402,376. Wireless receiving systems. WESTINGHOUSE BRAKE SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London.-(Assignees of Place, W. P. ; 442, Rebecca Avenue, Wilkinsburg, Pennsylvania, U.S.A.) Aug. 24, 1933, No. 23535. Convention date, Aug. 25, 1932. [Class 40 (v).] A wireless receiver comprising a dry-surface contact rectifier fed from a preceding high or intermediate frequency amplifying valve, is converted into an amplifier for gramophones in which the high or intermediate frequency amplifier serves as an audio frequency amplifier. The dry-surface contact rectifier 3 is fed from a high frequency amplifier 1 and feeds an audio frequency amplifier 4. The inductance 10 passes audio-frequencies, the capacity 11 compensates for the capacity of the rectifier 3 and the resistance 12 dissipates direct current due to the rectified carrier wave. To convert the circuit to a gramophone amplifier, switch 24 is opened and switch arm 23 is moved from contact A to contact B. As a result resistance 12 is placed across earth and the plate circuit of valve 1 since the inductance 10 has small resistance to audio-frequencies and inductor 16 has a low direct-current resistance and a high alternating-current reactance. An autotransformer may be included in lead 25 (Fig. 2 not shown). The invention is also applicable to the intermediate frequency amplifier and second detector of a super-heterodyne receiver (Fig. 3 not shown).

The determination of the above yarn properties is described, where lateral coherency is a measure of the resistance to the transverse pulling apart of two groups of yarn filaments, and where the increase in yarn bundle diameter is determined from the difference in diameter of the yarn bundle and the diameter of yarn tufts after the yarn has been given a defined tufting and steaming treatment. The filaments may have different properties. The yarns may have a denier of 500 to 5000, for upholstery or carpet pile fabrics, and may be made of polyamide, polyester, polypropylene, acrylic, modacrylic and triacetate materials. To make the yarn, continuous filaments 6. having at least 158 crimps per metre, are fed into chamber 12, and overfed by 2 to 15% into entangling means 14 (Fig. 3, not shown) fed by steam or gas hot enough to plasticise the filaments. Means 14 comprises at least three fluid jets. The yarn is false twisted at 22, e.g. by a fluid torque jet, and heat set at 20, e.g. by radiation or by steam- or hot gasimpingement, where the heat sets the latent twist in the surface filaments without disentangling the inner filaments. Chamber 12 or roll 10 may be heated. When the yarn is tufted, Fig. 2A, and heat treated, Fig. 2B, the tufts twist, shorten, expand due to crimp development, and remain coherent due to inner entanglement and the twist. The yarn may be used for cut pile or loop pile fabrics.
