[Class 78 (i)] Means for distributing granular material to a plurality of positions comprises a stationary feeding hopper, a plurality of hoppers mounted upon a carrier and arranged to move in succession past the feeding hopper, and closures for the outlets of the hoppers which are opened automatically by the movement of the carrier when each hopper reaches its predetermined delivery point. The hoppers 13, 14, 15, ..., Fig. 1, are carried by rings 16, 17 which are rotated about a circular furnace 10 by a driving chain 25. The outlet from the stationary hopper 46 is closed by a pivoted member 49 carrying a roller 52 which depends into the path of an upstanding projection 14a on each of the hoppers 13, 14, 15, .... As each projection encounters the roller, the member 49 is moved about its pivot 50 to permit the discharge of the contents of the hopper 46 into one of the moving hoppers, and is retained in the open position until the projection passes from beneath the roller. Each travelling hopper has a similar closure 44 which is actuated by the engagement of a, depending projection 14b with an upstanding projection 54b on a fixed shoot 54. A pipe 54a leads from each shoot to the bed of the furnace. The projections 14b, 54b are so arranged on the hoppers and shoots, respectively, that any particular projection 14b will engage only one of the projections 54b. Complete discharge of each hopper is ensured by arranging a rod 62 in the paths of all the projections 14b adjacent to a hopper 60. Any residue in the hoppers falls into this hopper and is returned to storage by a pipe 61. The rings 16, 17 may be replaced by a flexible or articulated structure.

Filed: 1937-06-15
Abstract: 484,860. Making metal foil. DEMEL, F. June 15, 1937, No. 16591. Convention date, June 15, 1936. [Class 83 (ii)] Gold leaf is produced by rolling between two protecting plates of a metal or metals other than gold, the plate on one face being then removed while that on the opposite face is only partially removed, the remainder being removed in a subsequent operation. A plate of gold 10 is rolled between plates 11, 12 of copper to reduce the gold to the thickness of foil required. The composite foil is then passed through a bath 16 of nitric acid to remove the thinner layer 12 completely, the remainder of the layer 11 being removed in a subsequent bath 20. The foil then passes through a bath 21 of water and a bath 22 of alcohol, and is wound with a paper strip 23a as it passes over a roll 24. The feeding rolls 31 and conveyers 29, and the roll 24, are driven by worm gearing from a common shaft 30. The plates 11, 12 may be of different metals, such as zinc and copper, instead of being of different thickness, so that part of one layer is left by the first dissolving bath due to the different rates of solution of the two metals.

Title: Method of growing quartz single crystals
IPC: C30B7/00
Filed: 1955-06-09
Abstract: <PICT:0807304/III/1> A quartz single crystal is grown on an elongated quartz crystal seed having its length extending substantially perpendicular to an X crystal axis and transverse to the Z crystal axis.  The length of the seed extends at an angle greater than 55 degrees to the Z axis of the crystal, preferably perpendicular to the Z axis. A seed crystal 40 (Fig. 1) which is small in cross-sectional dimensions perpendicular to its length, is cut so that it is elongated in the direction of the Y axis (perpendicular to a pair of <PICT:0807304/III/2> parallel opposite primary prism faces 13 and 16), its length being perpendicular to the X and Z axes.  A crystal is then grown on the seed, such as by exposing it to an alkaline aqueous solution in contact with silica under conditions of elevated temperature and pressure.  The crystal grows equally on opposite sides of the seed 40 in the direction of the Z axis (see Fig. 3), at a rate twice as fast on one side of the seed in the X axis direction as on the other side, and almost not at all on the primary prism faces 13a and 16a.  The crystal growth is stopped when it has a shape as shown in Fig. 3.  Piezo-electric plates may be cut along parallel planes at 35 degrees to the Z axis, or additional seed crystals may be cut from the bar.  Specification 761,643 is referred to.
