Abstract: 690,389. Hydraulic infinitely variable transmission gear. WEHINGER, R., KLADEK, K., and CHOWANETY, K., (trading as MASCHINENFABRIK EISENGIESSEREI WEHINGER & CO.). May 30, 1950, No. 13515/50. Class 69 (ii). The invention relates to an hydraulic infinitely variable transmission gear comprising an inner and an outer rotor each coupled for rotation with a different one of a driving and a driven shaft both the rotors being provided with radially disposed slots wherein are lodged vanes which are adjustable in the radial direction and which protrude into the intervening space between the two rotors, the space being filled with a viscous working medium. In Figs. 1 and 3 a driving shaft 1 carries a drum 2 and a cooling fan 29 and a driven shaft 22 is driven by a drum 12 through a bolt 24 and a slide block 25 which works in a radial groove 23 in a drum 21. As best shown in Fig. 3 the drums 2 and 12 carry respectively vanes 4, 14. The vanes are indicated by chain dotted lines in Fig. 1. They are held in place by rings 17, 19 respectively. The shaft 1 carries an eccentric 5 and the eccentric 5 carries a cylinder 6 in turn eccentrically mounted thereon. The eccentric on cylinder 6 has mounted thereon a guide sleeve 7 and a guide disc 9 carrying a guide cylinder 10 is concentricallv fastened to the sleeve 7. An eccentric 8 carries the outer drum 12. The eccentrics 5, 6 which are rotated in opposite directions are adjusted by means of a lever 46 which acts through a shaft 45, sprocket wells 31, 42, 33, 44, chain 41 and crossed chain 43. The eccentric 6 is driven through projections 34. The sleeve 7 is prevented from rotation by projections 38. A viscous medium, e.g. oil or grease, is contained in the space 50 between the drums 2 and 12. When the vanes 4 all protrude the same distance into the annular space 50 no torque is transmitted. Fig. 3 shows the gear set to give maximum ratio of transmission. This position is obtained by actuating the lever 46 so as to rotate each of the eccentrics 5, 6 through 90 degrees.

Abstract: 846,743. Degassing metals. STAUFFER CHEMICAL CO. May 3, 1957 [July 27, 1956], No. 14110/57. Class 72 [Also in Groups XI, XII, XXII and XL(a)] A process for vacuum-melting and degassing materials supplied in divided form comprises the steps of continuously feeding the divided material through an opening at a rate sufficient to maintain said opening completely filled with material, applying heat e.g. by means of an electronic discharge, or arc, or induction heating, to the material filling the opening to cause said material to melt and form a liquid seal across said opening and continuously extracting the gases released by the heated material from the material supply side of the liquid seal. As shown, a vacuum tank 1 houses a hopper 23 and a vibrating feed mechanism 25 from which material 22 passes into a duct 29 containing a feed screw 31 which forces the material into the forward end 39 of the duct to be heated and melted by a thermionicallyemissive cathode structure 44 mounted parallel to the discharge opening 39d of the duct 29. The duct 29 may be horizontal, as shown, but may slant upwardly or downwardly, and is preferably of copper, fluid cooled as for example, by a water jacket 41. The discharge end of the duct is slanted to form a pouring lip to guide molten metal from the fusion zone to drop into, for example, a water-cooled ingot mould 54 positioned within the tank 1 immediately below the pouring lip and having an open bottom so that an ingot 57 formed within the mould can be continuously withdrawn through a seal 55 without breaking the vacuum in the tank 1. In operation, gas released from the heated material, being blocked by the liquid seal at the discharge end of the duct, diffuses backward through the interstices of the divided material, is discharged into the tank 1 at the input end of the duct and is withdrawn by the vacuum system which should have sufficient capacity to reduce the base pressure in the tank 1 to a fraction of a micron Hg and to maintain the operating pressure where gas is being evolved to about two or three microns Hg so that an ionizable gas residue is left such that the space-charge is partially neutralized by positive ions.
