[Classes 120 (ii) and 120 (iii)] [Also in Groups XXIII and XXV] Twisted rovings or slivers of glass or other artificial fibrous material such as glass fibres, and coverings for electric conductors and other cores are formed by depositing the fibres in a mass on a support or collector 13 and withdrawing them therefrom by a rotating spindle 18 so as to form an interlaced and partly helical wrapping which is withdrawn endwise from the 'spindle to form' the roving or the covering for a core passing through the spindle; the spindle may be tapered and it has a peripheral speed greater than the speed of movement of the support. As shown the support 13 is a foraminous drum connected with a suction box, and the hollow tapered spindle 18, through which the core 21 passes, is positioned beside the drum with the adjacent portion of its surface parallel to the drum; the glass collected on the drum may be produced as described in Specification 428,720, [Group XXIII]

Balancing-apparatus for adjustable suspension.-A balancing device for rising and falling bodies such as window sashes comprises spring controlled drums and means for regulating the force exerted thereby to maintain a constant balancing force on the sash. The sash 7 as shown in Fig. 2 is balanced by a cord 11 passing over a fixed stud &c. 12 and connected at its ends to a differential spindle 10 supported by bearings secured to the bottom of the sash. The spindle is controlled by spring drums 14 and cords 13 wound on tapered rollers 16 fixed to the spindle, the taper being so chosen that a, constant lifting force is exerted. In a modification, the cords 11 may be wound on tapered drums fixed to the spindle 10 which is controlled by spring drums thereon connected by cords to fixed points. To give increased control the tapered members 16 may be made of elliptical or other eccentric cross-section so that a, varying movement is exerted thereon by the springs. Ratchet devices may be provided for adjusting the spring tension.

Abstract: 570,488. Secret transmission. PATELHOLD PATENTVERWERTUNGS- & ELEKTRO-HOLDING AKT.-GES. March 16, 1943, No. 4286. Convention date, Dec. 20, 1941. [Class 40 (iv)] Secrecy is obtained by attenuating at least a substantial part of the speech band, the attenuation being dependent on frequency and variable with time. The speech band may be divided into sub-bands of equal or different widths, the attenuation over a sub-band being constant or varying with frequency ; some or all of the sub-bands may be displaced in frequency, with or without inversion. The speech frequencies may be equalized initially. In the arrangements shown, original speech Zo is divided by filters into 5 sub-bands which are displaced, by modulation and selection of lower side bands, to a common range 3000-3500 #. The outputs of the modulators M are connected by a permutation switch R to selected attenuators W which may be greater in number than the number of sub-bands, the selection being changed from time to time. The outputs of the attenuators are connected over a further permutation switch Q to devices C providing different delays and connected by a third permutation switch P to modulators N which displace the sub-bands from the common range so that they are distributed over the whole of the speech range. The delay stage may precede the attenuation stage or the delay stage may be omitted. The receiver, which performs corresponding restoring operations, has its permutation switches synchronized with those at the transmitter. The permutations preferably occur at a frequency greater than syllable frequency. The attenuators may comprise valves or other elements controlled by variable voltages which may be differently phased voltages derived from a common source.
