Abstract: 100,062. Krupp Akt.-Ges. Grusonwerk, F. Feb. 6, 1915, [Convention date]. Magnetic separators.-In separators of the kind in which the magnetic field is divided into several zones of increasing or decreasing strength, all the magnetic poles are situated on the same side of the feeding-device, and the strength of the zones can be regulated. In the rotary-drum type of separator shown in Fig. 1, the magnet can be adjusted about the spindle 6 and comprises four poles 1, 1<1>, 2, 3, of which three are provided with laterally adjustable shoes 5 and one is longitudinally adjustable. The poles 1, 1<1> are excited by coils 4; but excitation may be effected by one coil only on one of the four poles, or by coils on the poles 3, 1<1>. The drum 7 may be of magnetic or non-magnetic material, or both. In other rotary-drum separators, two zone fields and three poles are employed, two of the poles being adjustable laterally and vertically and the other only adjustable vertically; or the poles may be fixed, and provided with laterally adjustable pole shoes. Separators of the travelling-band type, Fig. 4, are provided with four zone fields in which the poles 19 are adjustable vertically and laterally, the poles 20 are adjustable laterally, and the members constituting the pole 21 are pivotally mounted. The magnetic material is carried away by a belt 24 travelling at right-angles to the delivery band 23, which may be divided into several belts running at different speeds. In the form shown in Fig. 8, vertically adjustable pole shoes 35 are made in the form of rings, which serve also for the removal of the magnetic material. The rings are connected to the rotary disk 36, which is partly composed of non-magnetic material. The magnet poles 32, 33, 34 may act upon the vertical side faces of the rings 35. The rings 35 may be fixed and the magnet poles 32, 33, 34 adapted to rotate.

Abstract: 535,271. Elastic yarns; cores covering by winding. UNITED STATES RUBBER CO. Jan 11, 1940, No. 637. Convention date, Feb. 11, 1939. [Class 120 (iii)] [Also in Group XXV] An elastic yarn comprising a twisted rubber core and a textile cover spun thereon is made by rotating a package of rubber thread, pulling the thread endwise from the package to twist it in one direction and tension it a predetermined amount simultaneously advancing the twisted rubber thread and a textile roving to a spinning means which spins the roving about the core in the opposite direction so as to form a cover to the core and reduce the twist in the core ; preferably half the twist in the core is removed. As shown the core thread 10 is drawn downwards from the rotating supply bobbin 11 at a definite speed by feed rollers 16, 18 which tension the core a predetermined amount, the roller 16 being driven by a gear 17 and the roller 18 being freely rotatable in a pivoted arm 19. The twisted core from the rollers 16, 18 then passes to rollers 23 where it meets a roving 38 which is spun on the twisted core by the ring spinning device 40. The roving is formed from two ends 27 and is drafted by rollers 23, 24, 25 before becoming combined with the twisted core. In a modification the supply bobbin is mounted in a horizontal position and the twisted core passes over an idle roller before passing to the rollers 16, 18 and in another form the core is drawn upwards from the rotating supply bobbin. Specification 461,931 is referred to.

IPC: H01H53/10
Filed: 1927-01-10
Abstract: 275,077. Hailes, W. D. Jan. 10, 1927. Induction relays.-In a relay of the type comprising a rotor or vane which derives its torque from the magnetic fields produced by two field windings carrying alternating currents which are displaced in phase with respect to one another, the vane is shaped and mounted so that the torque due to the magnet system increases as the vane swings to either of the extreme positions and so that when either of the relay windings is de-energized there is an electromagnetic restoring torque tending to swing the vane to its neutral position. The vane 1 is mounted between the poles 5, 6 of a core 4 and the poles 10, 11, 12 of a core 9 on a shaft 2 connected by a rod 15 to a pivoted carrier 16 with arms provided with spring fingers 20 the contact tips 21 of which are adapted to engage with stationary contacts 22. The vane is of substantially semicircular shape with a segmental portion removed opposite to the diameter and is pivoted above its centre of mass. It is thus symmetrically disposed with respect to the magnet system only when in a position intermediate of the extreme positions and as it moves from the intermediate position in either direction the area of the vane within the air gap, and consequently the torque, is increased. The lower edge being straight extends, in the neutral position, over equal partial areas of all the pole pieces.
