Abstract: 902,155. Electromagnetic brakes. BREVETS AERO-MECANIQUES S.A. Jan. 19, 1961, No. 2206/61. Class 103 (1). A device 17 for maintaining a constant gap in an axially-applied electromagnetic brake comprises a spacer E having limited axial movement with respect to one magnet member 13 and a screw-and-nut unit A, B, in abutment between the spacer and the other of the magnet members 16, spring means 18 producing an axial thrust on the unit A, B to cause axial shortening and compensate for brake wear. An extension 1 of an electric motor shaft 4 carries a fan 3 and a double-sided brake disc 2, axially slidable on pins 10. The disc 2 is interposed between a carrier 8, rigid with the motor casing, and a pressure-plate 11 secured to an armature 13, the carrier and the plate being urged to grip the disc by spring units 12. The device 17 acts as a thrust-member to separate the carrier and the plate when an electromagnet 15 is energized on current being supplied to the motor. Manual release of the brake is provided by a lever 19 having camming balls 24 between the magnet member 16 and an abutment nut 25. The device 17 comprises a screw A mounted on the plate 8 and having a quick-pitch thread co-operating with a nut B having a domed cap C rotationally borne in a recess in the plate 16. The face of the nut B carries a friction ring D against which bears the flanged end of a spacer sleeve E having a collar F and nut G providing predetermined axial clearance, substantially equal to the desired magnet gap, with respect to the plate 13. A spring 18 prevents the sleeve E turning and provides an axial thrust to hold the cap C against plate 16. When wear occurs the relative movement of the plate 13 and carrier 8 is greater than the clearance in the collar and nut F, G and the flange E moves away from the friction-ring D. The spring 18 urges the nut axially causing it to move along the screw A until the ring D and flange E abut and the desired clearance is restored.

[Also in Group XV] A machine for labelling cylindrical articles comprises a rotatable label carrier 1 adapted to receive labels 8 in succession, means for rendering each label adhesive while still on the carrier, pressing means 16 for bearing against the non- adhesive side of each label, and means such as a belt or a roller for rolling the article over the label which is in contact with the pressing means. Each flat 2 on the wheel 1 has two suction openings 3 communicating with a head 4, the latter being non-rotatably supported by a bracket 48 and being urged by a spring into sealing contact with the wheel. The pairs of openings 3 lead to ports 46 which communicate successively, as the wheel rotates, with ports 51, 52, 53 in the head 4. A conduit 59 from port 62 leads to a suction pump, and conduits 54, 56 lead from ports 51, 53 to valves 58, which are opened and closed at appropriate moments by cams 68, on a shaft 69, driven by gearing from a main shaft. A conduit 60 leads from the valves to the suction pump. The label magazine 7, Figs. 4 and 5, is mounted on a platform 81 which is slotted for the passage of the wheel 1. The labels are withdrawn by suction nozzles 83 on arms 84 which are caused to transfer the labels to the wheel by cams 91 via cam followers 89 on arms 88 linked at 87 to arms 86 forming extensions of the arms 84. The cams are mounted on a shaft 92 driven from the shaft 69, the shaft 92 carrying another cam 101 serving to rock an arm 98 linked to an oscillating arm 94 carrying a roller 96 adapted to hold each label on the surface of the wheel.
