Title: Method and apparatus for separating slurry-state liquid into solid and liquid components
IPC: C13B15/00
Filed: 1971-08-10
Abstract: 1342756 Rotary drum filters KANEGAFUCHI BOSEKI KK 10 Aug 1971 [17 May 1971] 37554/71 Heading BID A rotary filter device comprises, as shown in Fig. 1, a rotary drum 1 and porous sheet filter material 2a which receives treated slurry from supply 3. Cake which forms on the filter is transferred to a belt 5, or roll 20, Fig. 2, by virtue of pressure and the smoothness of the belt's surface. A brush 8 and wash nozzle 9 remove any untransferred cake and a pressure drum 4 or applied vacuum removes the liquid. The belt may be adjustable in its spacing from the drum 1 which may be perforated whereupon the filter sheet material is made from a plurality of sheets adjacent ends of which are slotted into the perforations and nipped together. The adjacent portions of the sheets externally of the drum may be separated by suplementary sector shaped filter elements. Fig. 3-5 (not shown). Fig. 2 shows an auxiliary porous filter material 16 arranged around the porous sheet material 2a and tensioned by a roller 17. Nozzles 18, 19 are provided to wash the filter materials 2a, 16 respectively. If a plurality of sheets are used the point of contact between the upper surfaces of adjacent sheets may be bridged by a sector shaped filter element, Fig. 4 (not shown). The filter material 2a, which is elastic in the wet state and which may be superimposed on wire netting or perforated metal sheet, may be of polyvinyl acetal foam, optionally reinforced with resins or cottons, woven or non-woven webs, resinous fibres or metal wires; sponge; or porous non-woven sheet or felt. The auxillary filter material 16 may be of felt, filter cloth, perforated metal plate or wire net. The belt 5 on roll 20 may be of natural or synthetic rubber, polyvinyl chloride, polyurethane alone or with a woven or non-woven sheet material, or a metal sheet.

Abstract: 1,072,757. Endless moving sieves and bands. WEIMAR-WERK VEB. Sept. 16, 1964, No. 37799/64. Heading B2H. A device for separating potatoes from leaves and earth comprises an inclined frame 9 pivotably mounted at 10 for adjusting its inclination; a deflector 15 connected to the frame, an inclined separating apron 3 passing over reversing wheels 11 mounted on the upper end of the frame, and agitating wheels 12 connected to the frame and engaging the apron 3. The apron 3 comprises a pair of endless chains between which are secured transversely extending, parallel bars having tines 7 affixed thereto. Potatoes, leaves and earth are fed on to the apron 3 by an endless conveyor 1. Some loose potatoes tend to roll down the apron and are guided by a deflector 5 into a ring elevator or on to a transverse endless conveyor 6. The remainder of the potatoes with the earth and leaves are entrained by the tines 7 towards a guide wheel 8 which may be circular or elliptical. The inclination of the run of the apron between the wheel 8 and the reversing wheels 11 is adjustable by pivoting the frame 9 which carries, in addition to the elliptical wheels 12, spring-tined rakes 13, 14 extending over the entire width of the apron. Between the wheels 8 and 11 the apron is vibrated by the wheels 12 and the potatoes, small leaves and fine earth are thereby separated from the large leaves and clods of earth together with the aid of the rakes 13, 14 and fallthrough the apron, being then guided by the deflector 15 on to an endless belt 17 pivotably mounted at 16. The potatoes roll over the projections of the belt 17 onto the conveyor 6 while the fine earth and small leaves are entrained by the projections.

[Also in Division F2] In a bearing as claimed in the parent Specification for supporting the body of a motor vehicle, the spherical member A is subject to the effect of a magnetic field. The member A may be mounted in a housing C which receives a member B carried by a flow D. An electromagnet E, having alternate North and South poles, surrounds the member A which is made of paramagnetic material. The quantity of pressurized air supplied through a pipe F to form an air-cushion between the members A, B is decreased, owing to lines H of flux which, when the current is switched on, pass from the electromagnet E and through the member A. In a modification as shown in Fig. 2, the member B is free to slide in the housing C and a spring G may be positioned between the floor D and the member B. In other modifications, the member B may be made of paramagnetic material and the member A may or may not be of paramagnetic material, a face of the member B is recessed to receive one end of a spring, the electromagnet E may be replaced by a permanent magnet.

A device for the intermittent advance of a conveyer belt 1 of a film printing machine (not shown) has two pairs of belt driving elements each in the form of parallel rails 2, 2a, and 3, 3a, guided by rails 4. The driving elements are longitudinally reciprocated by a motor 7, gearing 8, and chain drives 9, 10 such that the movement of the pair of rails 2, 2a will be synchronous but oppositely oriented to the reciprocating movement of the pair of rails 3, 3a and vice versa. To establish a driving connection between the belt and the driving rails the latter are each provided with a suction channel 11 connected to a pump 14 via a reversing valve 13. Undesirable rubbing of the underside of the belt during the non- driving return movement of the driving rails is avoided by supporting each guide rail 4 on "pendulum" suspensions 16 secured to frame elements 17, 18. Longitudinal movement necessary to raise or lower the guide rails 4 is provided by hydraulic motors 39 connected in pairs to a reversing valve 42. A device 32 controls the raising and lowering of the rails 4, reversal and switching of the motor 7, and switching of the reversing valve 13 of the suction system.

In a method of making a die set for blanking out metal wherein a die member 20 comprises at least two compressible die blocks 23, 25 having compressed between them a die rule 28, the inner surface 31 is made parallel to the direction of movement of the die member and the free edge of the die rule is provided with a plane land 32 at 90 degrees to the surface 31, the free edge being spaced from the die blocks a distance such that an angle A, Fig. 6, is at least 10 degrees where tan A = T/E+M, T being the thickness of the die rule, E being the distance the free edge is located beyond the die blocks and M being the thickness of the metal to be blanked. The thickness of the die rule is that dependent upon the thickness of the work and the amount of projection beyond the face of the blocks. The width of the land varies according to the material to be cut, being relatively wide for hard or thick material and narrow for soft or thin material. The end of the blade is chamfered at 34 on the side remote from the die 44 by an amount to suit the width of the land. The included angle between the chamfer 34 and the land 32 is 135 degrees. The rear edge 36 of the die rule 28 is flush with the back of the compression blocks and bears against a rigid die backing-plate 21 attached to an upper bolster 12 which also carries bank plates 15 which compress the female die-member 20 and hold it in position. A stripper-plate may be inserted in the space between the blade 28.

[Also in Group XXIX] A valve has an opening in the form of a non-rectangular parallelogram controlled by slides having edges parallel to adjacent sides of the opening. A number of such valves may be employed to control the flow of fluids to be mixed from separate tanks whereby the proportions may be varied and the total flow may also be varied without altering the proportions. As shown in Fig. 3 three tanks 27, 28, 29 have openings 30, 31, 32 controlled by individually adjustable slides 60, 61, 62 for varying the proportions and by slides 70, 71, 72 which are moved together for varying all the openings simultaneously. In a modification, involving only two tanks, the two slides for controlling the total flow extend in the same direction from the openings as the proportion-varying slides, which move in parallel paths, and are linked to a common actuating shaft. Two sides of an opening may be initially adjusted by two further slides. A further modification is shown in Fig. 8 in which an opening 96 in a fixed cylinder 95 is controlled by edges 101, 103, of openings 97, 98 in axially or rotatably slidable cylinders 99, 100. A similar arrangement with openings in the slides may be embodied in plane form.
