Abstract: 952,870. Axial-flow blowers and compressors. L. R. CORVISIER. March 31, 1960, No. 11481/60. Heading F1C. In an axial-flow blower, compressor or the like, impeller blades 4 and diffuser blades 6 are adjusted in pitch, simultaneously or separately, by means of an electric motor 59. The motor 59 drives a shaft 45 through either of two sets of double-reduction worm gearing 60 or 601, the latter providing a more rapid adjustment for emergency use; the set of gearing to be used is coupled to the shaft 45 by a dog clutch 50 actuated by a servomotor 54. Shaft 45 is connected through bevel gearing 421 and splines to a vertical shaft which can be moved axially by means of a servomotor 104, 105 to engage a dog clutch connecting it to a shaft 261 whereby the pitch-adjusting pinions 71 of the diffuser blades 6 are rotated by a common gear ring 69. To adjust the impeller blades 4, a bevel gear 24 concentric with the impeller shaft is brought up to the speed of the impeller shaft by means of a motor 41 connected through bevel gears 39, 39a, to the planet carrier 44a of a differential gear 44, a sun gear 47 of which is connected through bevel gears 42, 37, shaft 26 and bevel gear 25 to the bevel gear 24. Bevel gear 24 is then coupled by a servomotor-actuated dog clutch 88 to a gear wheel 19 carried by the impeller. Motor 59 is then started in the required direction to drive shaft 45 which rotates the other sun gear 48 of the differential gear 44 to vary the speed of gear wheel 19 to a value above or below that of the impeller shaft, whereby the gear wheel 19 is caused to rotate relative to the impeller, thereby causing the pitch-adjusting pinion 14 of each impeller blade 4 to rotate relative to the impeller. Shafts 26 and 261 may be arranged to be moved axially to bring bevel gears 24, 25 and 241, 251 into or out of mesh, the associated dog clutches then being omitted. The electric motors may be replaced by fluid-actuated motors.

Abstract: 1,115,687. Vibratory finishing. J. F. RAMPE. 14 March, 1967 [16 March, 1966], No. 11937/67. Heading B3D. A vibratory finishing machine includes: (1) a tub unit mounted on a support by resilient suspension means; (2) a pair of shafts mounted on the unit to rotate relatively thereto about spaced parallel axes, and each provided with eccentric means to cause it to exert on the unit a radial force rotating with the shaft to produce orbital movement of the unit about axes parallel to the shafts; (3) a tub mounted in the unit between the said axes for containing a shiftable load comprising articles to be finished and finishing medium; and (4) means for driving the two shafts in synchronism. A tub 6 has a top opening 6b and in one end wall an opening 6c closed by a sliding door 8; outside the opening 6c is a shoot 9. Horizontal channel members 11 are welded to the flat ends of the tub, and the ends of the members 11 are connected to uprights 3 of the supporting frame through elastomeric spacers 12, e.g. of neoprene, rubber &c. Horizontal channel members 16 are welded to the widest portion of the cylindrical wall of the tub. Each channel 16 carries two heavydutybearing mounts 17 having roller bearings 20 supporting a shaft 21 carrying a cylindrical eccentric weight 22. The weight 22 is enclosed in a tubular housing 23 interposed between the mounts 17 which are connected by tie rods 18. The weights are in phase. The shafts 21 are connected by flexible or self-aligning couplings 24 to the shafts of D.C. motors 26 controlled by a unit 30 preferably of the selenium rectifier type so as to run in precise synchronism. The motors are supported on platforms 33 mounted on support plates 32 welded to the ends of a channel member 31. Each plate 32 has vertical slots through which screws 36 project from fixed vertical guides 37, each screw carrying a locking nut for holding the support plate in desired relation to the guides.
