Wireless tuning-apparatus, adjustment devices for.-An adjustment device for inductance coils comprises a conoidal cam rotatable through 360‹, the slope of its peripheral surface varying throughout from a minimum to a maximum. In one construction, Fig. 1, the movable coil 6 is hinged to a base 1 and is pressed into engagement with the sloping surface of a conoidal cam 4, Fig. 4, by a spring 7. Minimum coupling between the coils 2, 6 is obtained when the holder 5 lies along the line a - - b, and maximum coupling when it lies against the vertical surface at b. A vernier adjustment can be obtained by making the angle of slope smaller. The axes of rotation of the operating-spindle and coil may be perpendicular to or parallel with each other and the coil may be moved in its own plane. In another arrangement, two movable coils are adjusted by concentric spindles each carrying a conoidal cam, and one of the cams may have a slope differing from that of the other.

Abstract: 218,635. Cerisier, C. July 7, 1923, [Convention date]. Rolling annular bodies.-Hand operated tools of the type comprising a removable hand-driven roller and a second roller movable towards the first for enlarging rings, such as jewelled or plain finger rings by subjecting them to a rolling operation over a part or the whole of their periphery have the rollers in direct moving connection with each other. A hand tool for enlarging a ring 10 consists of a pair of arms 1, 2, pivoted together at 3, the arms 1 having a pair of lugs 4, 5 which receive a plain roll 9 and a pinion 8 pinned thereto, both mounted on an axle pin 6. The pin 6 has a handle 7 and also a rib which is passed through a notch in the lug 4 into a similar notch in the pinion. The grooved roller 14 and pinion 15 are mounted on a removable pin 13 between lugs on the movable arm 2. With the movable arm in the open position the ring is placed over the roll 9 and the roll 9 and pinion 8 then assembled by the pin 6 between the lugs 4, 5 and the roll 14 and pinion 15 assembled in the arm 2. The handle 7 is then turned to rotate the rolls, pressure being applied by the operator through the arm 2 either direct or through a screw. For plain rings rotation is continuous in one direction but for jewelled rings the rotation is alternately in opposite directions. The teeth of the pinions are deep enough to permit of their use for rings of different thicknesses and the rolls 9, 14 are of different diameters and the pinions have a different number of teeth so as to prevent slipping between the ring and the rolls. A movable stop 20 is provided between the arms to. limit the pressure particularly when operating on rings of soft metal. A stem 22 on the stop receives interchangeable grooved rolls 23. The pinions may be replaced by chain and sprocket gear, and one of the lugs 4, 5 may be hinged so as to facilitate assembling of the roll 9. The arm 1 may be fixed to a table on a bench.
