Title: Arrangement for Suppressing Harmonics in Alternating Current Dynamo-Electric Machines.
Filed: 1905-06-07
Granted: 1906-02-15
Abstract: 11,931. Soc. Anon. Westinghouse, and Leblanc, M. June 10, 1904, [date applied for under Patents Act, 1901]. Armatures; field magnets.-For the purpose of suppressing the harmonics produced in the armatures of alternating-current machines or rotary converters, or in the primary windings of i nduct:on machines, the field magnets or the secondary windings are provided with special circuits of high resistance closed upon themselves or with circuits of low resistance closed through high resistances. In the arrangement shown in Fig. 1, metal rods of high resistance are disposed in grooves in the pole faces with their ends electrically connected on the two faces of the field magnet, and the field coils are closed on an external circuit possessing considerable selfinduction. A modification is described in which alternate pairs of poles are furnished with amortisseur windings of low resistance, the remaining poles being fitted with the harmonic-suppressor circuits. The rotor of a three-phase induction machine is shown in Fig. 3. The harmonic-suppressor is constituted by a squirrel cage made of rods of german silver situated in the same slots as the armature windings, which terminate in three collecting-rings allowing of their being closed through self-induction coils, or preferably, as shown in Fig. 5, through the rotor winding R of an auxiliary direct-current machine mounted on the same shaft. The rotor revolves within a laminated closed ring S, and, in a bipolar arrangement, the brushes a, b, c are set on the commutator at angles of 120 degrees apart, thereby producing a rotary field. If the rotor revolves at a lower speed than the field, the windings between the brushes bebave as if they had self-induction. If the rotor rotates faster than the field, the rotor circuits act as condensers. The speed of the rotor is adjusted so that it acts as a capacity for useful currents and as an inductance for high-frequency currents produced by the harmonics. In induction machines of the type shown in Fig. 3, the stator windings I, II, III may be connected to the brushes on the rotor R either directly, as shown in Fig. 6, or through self-induction coils 1, 2, 3, Figs. 7 and 8, to prevent the rotor circuits between the brushes from acting as a screen to the fluxes produced by the harmonics in the stator. In place of the squirrel-cage damper, high ohmic resistances may be connected in parallel with the self-induction coils 1, 2, 3 or in shunt with the brushes in Figs. 5 and 6.

Abstract: 5940. Stubley, C. H. March 12. Sifting. - Transverse angle: shaped strips are arranged above and below the sifting-surfaces of sieves to raise the larger particles and propel them forward, and to throw balls or the like against the sifting-material to prevent clogging. The sieve box may be inclined or horizontal, and may be reciprocated or rotated. Several boxes may be used in one machine, and the transverse strips may be perpendicular or inclined to the direction of motion of the material to be sifted. The upper strips B are arranged so that the small particles may pass below them. They are hollow below, and their upper surfaces make acute angles with the sifting-surfaces F and are oppositely inclined to that surface. The upper surfaces of the strips B<1> below the sieve are inclined in the opposite direction to the strips B so as to propel the balls C upwards towards a pipe J, through which they return to the lower end of the sieve. The shape, angle, and position of the strips B, B<1> may be varied. According to the Provisional Specification, the surface of the strips B<1> may be inclined so as to propel the balls in the same direction as the flow of the material; or the balls may be placed on the strips B, which are then inclined in the opposite direction to that shown.
