摘要： A compensating plate for a pressure filtration cell including a generally cylindrical liquid-feeding vessel and a base removably connected to the feeding vessel by means of a flanged joint, the removable base forming a filter holder, in which an outer edge of the plate is engaged in a flange between the liquid-feeding vessel and the filter holder and, on its upper side, the outer edge of the plate is sealed against the liquid-feeding vessel by means of a circumferential seal. The compensating plate has a central opening corresponding to the size of a filter placed in the filter holder, the plate having a slight conical depression toward the said opening. The opening passes into a downwardly extending cylindrical frame whose bottom edge presses the filter or a filter packing against the filter holder in a sealing manner when the filter holder and the liquid-feeding vessel are forced axially toward one another such that the compensating plate functions as a seal between the liquid-feeding vessel and the filter holder formed by the removable base.

摘要： A syringe is adapted to overcome a pressure resistance at its outlet as may be provided, for instance, by a filter in communication with the outlet and through which the syringe is to pump a medium, particularly a liquid medium, for filtration. The syringe comprises a first cylinder containing a piston and a piston rod. The piston rod is fixed to a second piston sliding within a longitudinal bore in the first-mentioned piston. The bore and the second piston cooperate to define an air-filled pressure chamber connected to a first cylinder chamber, defined by the first piston and the first cylinder, by a valve. Inward movement of the piston rod produces an over-pressure (e.g. 16 atmospheres) in the pressure chamber to open the valve to apply the over-pressure to the liquid or other medium in the cylinder chamber to overcome the pressure resistance of the filter and enable the liquid to be forced through the filter.

摘要： A pressure filtration cell includes a reservoir for liquid to be filtered, a filter at the bottom of the reservoir, and a manually actuable pump for supplying compressed air. The pump is detachable from the reservoir. The air is introduced near the bottom of the reservoir closely adjacent the filter so as to create turbulence in the liquid and across the filter. The turbulence is of a pulsating nature due to the intermittent operation of the pump. Thus, the pump is easily portable for use anywhere and creates a "dynamic" filtration process even without a mechanical stirrer. If used in a laboratory, the cell can be provided with a rotary, magnetically operated stirrer mounted on a relatively short axle.
摘要翻译：压力过滤单元包括用于要过滤的液体的储存器，在储存器底部的过滤器，以及用于供应压缩空气的可手动致动的泵。泵可从储存器拆卸。空气在靠近过滤器的储存器的底部附近引入，以在液体中并跨过过滤器产生湍流。由于泵的间歇操作，湍流具有脉动性质。因此，即使没有机械搅拌器，该泵也易于携带以便在任何地方使用，并产生“动态”过滤过程。如果在实验室中使用，电池可以设置有安装在较短轴上的旋转式磁力搅拌器。

摘要： A syringe of the slide piston pump type is adapted to overcome a pressure resistance at its outlet as may be provided, for instance, by a filter in communication with the outlet and through which the syringe is to pump a medium, particularly a liquid medium, for filtration. The syringe comprises a cylinder containing a piston, and a piston rod. The piston rod is fixed to a second piston sliding within a longitudinal bore in the first-mentioned piston. The bore and the second piston cooperate to define an air-filled pressure chamber connected to a cylinder chamber, defined by the first piston and the cylinder, by a valve. Inward movement of the piston rod produces an over-pressure (e.g. 16 atmospheres) in the pressure chamber to open the valve to apply the over-pressure to the liquid or other medium in the cylinder chamber to overcome the pressure resistance of the filter and enable the liquid to be forced through the filter. A safety pressure release is provided to prevent bursting or inadvertent release of the liquid medium.
