Abstract: 472,719. Ball and like mills. SCHIEFERSTEIN, G. H. Aug. 27, 1936, No. 23542. Convention date, June 16. [Class 59] The apparatus comprises a receptacle b, containing the grinding bodies and material to be ground, resiliently mounted by elastic members c within a vibratable mass or outer casing a to form a two mass system and means such as an eccentric x<1> for agitating at least one of the masses b to perform circular oscillations and to cause both masses to oscillate relatively, the oscillatory characteristics of the system being varied by varying the frequency of the circular oscillations or by the initial tension of the elastic members c so as to give optimum results. As shown in Figs. 1, 2, the outer casing a is resiliently suspended at h and supports an axial shaft y on which the eccentric x<1> is resiliently connected by springs f to the inner casing b. The shaft y passes through a tube e in the casing b, the latter being supported from the casing a by rubber blocks c which may be mounted on levers pivoted to the casing a and adjusted toward the casing b by screws. The shaft y is rotated by a pulley and the eccentric x<1> vibrates the casing b which in consequence also rotates slowly on its axis. In a modification the tube e is extended through the casing b to form a bearing for a ring carrying a crank-pin which is engaged by a crank on the shaft y. In Fig. 5, the shaft y is cranked at the ends and carries cylindrical or conical pulleys k', k2 which engage the casing b by resilient members f, the casing b being connected to the outer casing a by resilient members c. The vibrations may be obtained by the rotation of an eccentric mass m<1>, Fig. 7, mounted on the shaft y which is carried in bearings in the casing b. In Fig. 8, the drum b is vibrated through lever arm k<1> of T-shape, the ends of the T forming elliptical bearings v', mounted in a ring r pivoted on elliptical bearings at right-angles to the bearings v<1>, in the manner of a cardan joint, the free end of the T engaging in a block s which may be slidable in a slot in a driven-member u at the end of the shaft y. In a modification, the ends of the T are fixed to the casing a and the free end engages in the block s slidable in the member u. The material may be ground in the outer casing a, and the casing may consist of separate rings, the shape of the casing b may also be varied.

Filed: 1925-09-30
Abstract: 240,843. Compagnie pour la Fabrikation des Compteurs et MatÚriel d'Usines Ó Gaz. Sept. 30, 1924, [Convention date]. Induction relays are arranged to produce their maximum torque when supplied with current of a predetermined frequency by providing in the circuit of one of the parallel connected actuating electromagnets a condenser adjusted so that the two fields actuating the pivoted member are almost in quadrature. In the relay shown in Fig. 1 having two parallel connected coils E1, E2 on cores A1, A2 the coil E2 has a suitable capacity C in series with it in order that it shall respond to a given frequency. To make the ratio of the potential at the relay terminal to the supply voltage as high as possible an additional capacity C, may be placed in series with the relay as shown in Fig. 5. For high frequencies the gap d, Fig. 1, between the magnet poles is made large compared with the air gap in which the disc D is situated so that flux leakage is reduced. The Specification as open to inspection under Sect. 91, (3) (a) also describes a single-winding induction relay having a suitable condenser in series with this winding and short-circuited coils or shading rings on the divided pole-pieces of the electromagnet. This subject-matter does not appear in the Specification as accepted.
