A distributer head 8, which is fixed against rotation, has spaced ports communicating, through orifices in the plate 6, with the plates 5. The plates 5 are maintained in the radial direction by springs 17. The juice to be filtered enters the distributing pipe 24 under pressure and passes through the cloth covering the plates 5, the insoluble suspensions being deposited on the surfaces of the plates. Each plate 5 is successively brought into communication, through the ports in the head 8, with decreasing counter-pressures, simultaneously with the increase in thickness of the deposit. The deposit is stripped from the plate 5 by back-flushing filtrate, via a port in the head 8. The deposit falls into a hopper 9 having an agitator mounted on a shaft 10, which is provided with apertures 16 and is rotated so that the deposit passes several times through the apertures while being carried to the outlet 25. Decantations at the bottom of the tank 1 are returned to the hopper 9 by an arm 11 rotating on the shaft 3. During the back-flushing operation the plates are moved apart by engagement with the cam surface 12. Removal of the deposit may be aided by jolts imparted to the filter plates by a cam surface or may be aided by stripping strings which are stretched across the plates and carried in a frame which is moved vertically by a cam surface. The filter plates may be covered by a wide mesh net which strips the deposit by the relative movement between the net and the filter cloth when the latter is inflated by the internal counter pressure.

Filed: 1938-10-18
Abstract: 520,290. Packeting - machines. GEE, H. T. P. (Soc. Anon. Lanificio Rossi.). Oct. 18, 1938, No. 30169. [Class 94 (i)] The machine packs articles such as shuttles, cartridges, and the like in rows in a box, which is moved in steps to accommodate the successive rows, and the movement of which is reversed when a layer has been inserted.' The shuttles are fed by a conveyer 1, Fig. 1a, past a counting device to a position where an ejection fork transfers them seriatim, into a collecting box 9, Figs. 1 and 7. The side walls of the box are formed by pivoted pieces 11, Fig. 7, curved to extend beneath the ends of the shuttles to support them. The sides are normally spring- urged into the supporting position. A temporary bottom for the box is formed, while it is in the loading position, by an endless band 12, held in position by pivoted arms carrying the rollers. The band is not positively driven, but is moved by the engagement of a projection 36. thereon by the foremost shuttle which, when the collecting-box is full, strikes a stop 13 and releases a rod 14 for movement by a spring 15. The rod controls a system of levers associated with a friction-clutch 16 and connects a cam-shaft 19 with its motor 17. Cams are provided on the shaft for stopping the motor driving the conveyer when the collecting-box is full, for causing the belt 12 to be swung away from its temporary position at the bottom of the collecting-box, and for starting the motor 23. The motor 23 operates a shaft 25 having pinions 26 engaging racks 27 which support the box, which is thereupon lowered into the packing-case c. When the box reaches a position in which it presses upon the bottom of the packing-case, or upon a previously deposited row of shuttles the pressure is transmitted through the shuttles to the inner cover 49, Fig. 7, causing the sides 11 to be moved outwards to disengage the shuttles, which are laid in a row in the case. The pressure also operates a reversing mechanism to cause the box to be raised to its upper position to receive another row. The truck 33 supporting the packing-case c is displaced by a distance equal to the length of the shuttles. When a complete layer has been deposited, the truck is held stationary while the first row of a new layer is deposited on the last row of the previous layer. The movement is then reversed, and the deposition of the layers proceeds in the reverse direction.
