摘要： A press for expressing liquids from solids or for forming moulded blocks comprises a frame including a facing pair of upper and lower platens, a filter cloth extending across the lower platen, and a fluid expansible bellows device located between the platens and serving to press material against the filter cloth. The bellows device is comprised by the novel arrangement of a first flexible diaphragm connected to the upper platen and forming a fluid chamber with the upper platen, and an inflatable bag member between said first flexible diaphragm and the lower platen. The inflatable bag has an upper diaphragm wall back-to-back with said first diaphragm and a lower diaphragm wall for pressing material on the filter cloth, the inflatable bag and the fluid chamber being in fluid communication; and the bellows device includes an inlet for pressure fluid.

摘要： 1,271,494. Press filter. L. B. HOLLIDAY & CO. Ltd. 2 May, 1969 [9 May, 1968; 24 Oct., 1968], Nos. 22009/68 and 50525/68. Heading BID. A hollow, perforate, cylindrical core 1 is covered by sheet filtering medium and is axially movable into and out of a cylindrical housing 2 which is lined by an inflatable sleeve 5. Slurry pumped or flowing under gravity into space 13, between the medium and diaphragm, is first allowed to drain through the medium, then the inlet valve is closed and sleeve 5 inflated by compressed air or water, forcing more of the liquid content of the slurry through the medium to outlet 23. The sleeve is deflated, the pressure fluid being returned to its storage tank, and the core 1 is withdrawn from the housing by ram 24, carrying the adhering filter cake, which is then removed. In Fig. 1, ram 24 moves the core and end plate 17, to which it is secured by struts 25 which extend through slots 27 in hollow shaft 3 along which the core slides. Ram 24 is pressurised to hold the core in its inserted position in Fig. I, but Figs. 10 to 13 (not shown) illustrate an arrangement of latches which lock plate 17 to the housing, after which the ram pressure need not be maintained. Figs. 4, 5 (not shown) illustrate the annular seals which close the two ends of space 13 when the core is inserted. Fig. 6 (not shown) illustrates a preliminary screen across slurry inlet 22, and Figs. 7, 8, 9 (not shown) illustrate the construction of the core, which is covered by a rubber sleeve (64) having external, axial and circumferential grooves to drain the filtrate to openings (19). The filtration may be preceded by applying a filter aid of carbon or diatomaceous earth to the filtering medium, and the filter cake may be washed and dried by passage of hot gas before withdrawing the core. The filtering medium may be cleaned by backwashing. Fig. 14 (not shown) illustrates the circuits for slurry, filtrate and pressure fluid. The housing may be metal lined with rubber or chlorinated polyester. The filtering medium may be cloth, secured to the core body by rubber rings or plastics braiding. Various applications are suggested, particularly recovery from suspension of Acid Yellow 17 and 2 naphthol-3, 6-disulphonic acid.

摘要： An arrangement for pressing materials containing liquid has mobile press container with an container interior that is divided by a press membrane into a pressure medium chamber and a pressing medium chamber. A filling and emptying opening, which can be closed in a pressure-tight manner, allows material to be pressed to be added to the pressing medium chamber. At least one drainage element is arranged in the pressing medium chamber. An interior of the drainage element communicates with a juice discharge of the press container. A turning device, in which the mobile press container is temporarily received can be rotated during a pressing operation from a filling position, about an angle of less than 360°, more particularly of less than 270°, in mutually opposing directions of rotation about an axis of rotation. There is also described a method for pressing liquid-containing materials.

摘要： An in-situ double vacuum debulk (DVD) composite repair system designed to produce partially or fully cured autoclave-quality hot-bond composite repairs on contoured structures. The system provides vacuum pressure for hot bond repairs to be performed on flat and contoured structures using one set-up capable of debulking (partially curing) and then fully curing composite repairs on composite and metallic aircraft structures. The use of in-situ DVD also eliminates handling of the patch/adhesive when transferring from an off-aircraft DVD chamber to the repair site on the aircraft. This can increase the probability of successful repairs because the possibility of contaminating and misaligning the adhesive and repair patch are eliminated.

摘要： System and method for compacting a composite ply layup comprising a forming tool comprising a top surface and a composite ply layup laid up along the top surface of the forming tool. A single release film comprising a top surface and a bottom surface, wherein the bottom surface of the single release film comprises a first non-planar bottom surface. The first non-planar bottom surface placed over a top surface of the composite ply layup. A venting port operatively coupled directly to the top surface of the single release film. A vacuum source operatively coupled to the venting port and configured to generate a vacuum to the single release film, such that the first non-planar bottom surface of the single release film defines a breather path for the vacuum generated by the vacuum source to distribute over the top surface of the composite ply layup.
