Abstract: 1,068,637. Friction clutches; electromagnetic brakes. ZAHNRADFABRIK FRIEDRICHSHAFEN A.G. Sept. 4, 1964 [Sept. 11, 1963], No. 36357/64. Headings F2C and F2E. The air gap between a magnet body 32 and an armature plate 35 of a spring-engaged, electromagnetically disengaged multiplate friction clutch, or brake, may be externally adjusted through screw-threads 45, 46 on the magnet body 32, or in an annular member rotatably mounted and axially secured thereon, and on, or in, an outer friction plate carrier 39. In the clutch, as shown, the magnet body 32 and carrier 39 are adjustably screwed together and connected by an abutment flange 42 fast to a driven gear-wheel 43 rotatably mounted on a driving shaft 31, the unit surrounding an armature 35 biased, by a plate spring 37, into engagement with the clutch pack 40, 41. Tommy-bar or spanner holes 47 are provided around the periphery of the magnet body to operate the screwed air-gap adjustment after removal of a cover-plate 48, normally serving to secure the magnet body 32 and carrier 39 against relative rotation. In the brake arrangement of Fig. 1 (not shown) an annular member, rotatably mounted and axially secured on the magnet body, and outer plate carrier are adjustably screwed together and connected by a flange to a casing wall, the annular member having peripheral spanner holes for effecting the air-gap adjustment. The armature is biased to engage the friction pack by springs the force of which can be varied by means of threaded plugs to regulate the brake engagement pressure.

Abstract: 1,026,385. Panoramic cameras. CINERAMA CAMERA CORPORATION. Oct. 5,1962 [May 17, 1962], No. 37874/62. Heading G2A. A panoramic camera having a removable film cassette has a-bearing on which it can be rotated about a vertical axis passing through the lens, so that the image at the focal plane remains stationary in space, the camera also having a wheel displaced from said axis, the wheel being adapted to engage the film in the cassette and unwind it in a direction opposite to the direction of rotation of the camera. In the form shown, the camera comprises a housing 1 into which fits a removable cassette or magazine 14. The power derives from an electric motor 16, which drives via gears 18 and 20 a pinion 22 fixed at one end of a shaft 24. The other end of the shaft carries a pinion 26 which meshes with a large gear 28 held stationary at the end of a supporting column 30. Thus pinion 26 rolls round the stationary gear to rotate the whole camera on column-30 as axis. At the same time a pinion 32, fixed to gear 20, engages with a gear 34 rotating freely on shaft 24. Gear 34 has a pinion 36 engaging, via gear 38, a gear 42 coaxial with the large gear 28. Gear 42 meshes with a gear 48 fixed to a sprocket 44 which engages the perforations in the film. Thus gear 18 of the motor shaft drives one gear train to rotate the camera on support'30, and also another gear train to rotate the film-transporting sprocket 44. The ratios of the two gear trains are so correlated that as the camera moves, the film moves in the opposite direction with the same speed, so that it actually remains stationary in space. The axis of rotation of the camera is arranged to pass through the principal point of the lens, so that the image is stationary as well as the film.
