A filter press apparatus comprises a series of press units arranged side by side in parallel relation, each press unit having a rail or rails on which filter plates are individually supported for movement to and from a discharge position and a common slurry source; and a traversing platform having an extension rail or rails and capable of being aligned with individual units for discharge thereof. The filter plates are withdrawn for discharge by means of a control device on to the rails of the platform. In Figs. 1 and 2, a series of filter press units 1 have the individual filter plates suspended from rails 2. The traversing platform 3 moves along guide rails 4 and has a rail 5 which may be aligned with rail 2 when a filter press unit is to be discharged. A power operated carriage 7, suspended from raid 5, withdraws the filter plates to position 6 where they are discharged and their contents emptied on to a conveyer 8 which passes the material to conveyer 9. In another embodiment, Figs. 3-5 (not shown), the filter press units are arranged one above another and the movable platform moves up and down to facilitate discharge of the press units. The material discharged is retained in a trough mounted on rollers on the platform and is passed to a conveyer belt situated at the bottom of the apparatus when the platform is in its lowest position.

Title: Tobacco smoke filters
Inventor: SHEPHERD THOMAS HUGH
IPC: A24D3/08
Filed: 1969-08-27
Abstract: 1,255,564. Tobacco-smoke filters. NATIONAL PATENT DEVELOPMENT CORP. 27 Aug., 1969 [29 Aug., 1968], No. 42590/69. Heading A2C. [Also in Division C3]  A tobacco-smoke filter comprises a substantially cylindrical charge of a hydrophylic polymeric compound, said polymeric compound being highly porous and having a high surface area and being a polymer of a hydroxy lower alkyl acrylate, a hydroxy lower alkyl methacrylate, a hydroxy lower alkoxy lower alkyl acrylate, a hydroxy lower alkoxy lower alkyl methacrylate, acrylamide, methacrylamide, methylol methacrylamide or diacetone acrylamide; the highly porous, high surface area characteristics being produced either by preparing the polymeric compound in the presence of a blowing agent to foam it, or freeze drying a mixture of the polymer and water. Many suitable monomers, foaming agents and free radical catalysts are specified. Ultra violet or gamma radiation may replace the catalyst. Preferably the polymer is crosslinked, and many suitable agents therefor are specified. The monomers may advantageously be copolymerized with an ethylenically unsaturated mono or polycarboxylic acid, or less preferably with a partial ester of an ethylenically unsaturated polycarboxylic acid, and many such comonomers are specified. The smokefiltering material may be used as a carrier for humectants such as glycerine, propylene glycol, ethylene glycol, sorbitol, mannitol or corn syrup, and may be impregnated with flavours such as menthol, peppermint, or natural or artificial tobacco flavour. In the examples, 2-hydroxy ethyl methacrylate was polymerized in bulk, together with ethylene glycol dimethacrylate as cross-linking agent or with itaconic acid as comonomer, using tertiary butyl peroctoate as catalyst and sodium bicarbonate as foaming agent, to produce a foamed polymer which was then pelleted and used as a tobacco-smoke filter material in a cigarette. The pelleted polymer was also used with the addition of a 50% aqueous glycerine mixture with and without the further addition of tobacco flavour or tobacco flavour plus menthol. In further examples, 2-hydroxy ethyl methacrylate was polymerized in aqueous solution, with and without ethylene glycol dimethacrylate, with ammonium persulphate as catalyst, using sodium bisulphite as foaming agent either alone or together with sodium bicarbonate and citric acid, and the resultant foam polymer that precipitated was then frozen and freeze dried and the dried product granulated and used as a tobacco-smoke filter. The filter may be employed in cigarettes, cigars, pipes &. alone or in combination with other filters such as activated carbon, plasticized cellulose acetate fibres, corrugated paper or polyethylene particles or fibers.

Abstract: 1,240,371. Bag feeding; opening and filling. W. R. GRACE & CO. 11 Sept., 1968 [11 Sept., 1967], No. 43250/68. Heading B8C. A bag feeding, opening and filling apparatus comprises a support table and tape pulling unit 15 to feed a continuous chain 130 of imbricated bags, e.g. 131, to a loading position which are then opened by inflation with air and filled. The chain of bags are adhered to a pair of parallel, sticky tapes which are pulled from container 143 over rollers 73, 74 over the support table 21, twisted to run over knurled rollers 63, 64 and are crimped together by gear-wheels 30, 56. These gear-wheels are actuated to pull the tapes and bags when spring 51 is released on to valve (47, Fig. 2, not shown) starting motor 43. Air blower unit 16 operates to open and inflate bag 131 through shoot 113. Inlet 111 is closed by piston-operated gate 117, in response to cooperation of cam 125 and lever 124 on movement of tray 12. Support table and tape pulling unit 15 is pivoted at 82 and actuated by cylinder 84 in response to switch 86. The article to be loaded is placed on tray 12 which is pushed into the inflated bag, shutting off the air supply in so doing. The article is pushed from the tray 12 into the bag 131, which is thereby simultaneously stripped from the tapes, releasing spring 51 to cause the tapes to pull the next bag into position as tray 12 is retracted to allow air supply to recommence. To change the size of bags or the tape, unit 15 may be pivoted by switch 86 and the tapes released by means of toggle (57, Fig. 2, not shown) so that the chain of bags and the tapes may be withdrawn and replaced in container 143 so that a new chain may be connected. In another embodiment (Figs. 8-10, not shown), the support table and tape pulling unit (215) is fixed and the tray and blower assembly (315) is pivoted manually to facilitate application of the tapes to the front face (224) of unit (215). Tray (212) is not reciprocated, blower (210) being actuated either by spring (251) or separately. In a further embodiment (Figs. 11-13, not shown), a cartridge (400) enclosing a rotatable spool (403) is clipped on to the front face of the tape pulling unit (415) and effects the pulling of the tapes and chain of bags by means of shaft (431) and couplings (401-402).

When coal or a similar material falls down an overflow shoot (not shown) associated with the output of an elevator (not shown) microswitches A1, A1, are opened. This results in the de-energization of a solenoid C and consequent opening of a contactor C1 controlling the motor driving the elevator. The solenoid C at the same time closes a contactor B6 so as to energize a motor B1 driving a cam B4. The latter comprises a timing device which after a predetermined period results in the closing of a contact B. This has the effect of re-energizing the solenoid C, thus closing the contactor C1 and opening the contactor B6. The elevator motor is thus restarted and the cam B4 is returned to its initial position by a spring B5. A solenoid B2 operates when the motor B1 is energized to engage a clutch between the motor Bland the cam B4. There may be a single micro-switch instead of the two shown. Each switch A may be operated by a probe which may carry a striking plate on it.
