摘要： A program controlled dishwasher in which magnetic sensors provided adjacent to the dishwasher door respond to magnetic fields of predetermined polarization provided by permanent magnets in a catenulate magnetic key mounted on a dishwasher caddy in a position adjacent the magnetic sensors when the caddy is in the tub of the dishwasher, for generating a verifiable code pattern readable against dishwasher stored programs for the selection and actuation of a program specific to the articles which are stored in the caddy for washing. The polarization patterns on the caddies are specific to the kind of articles stored therein and may be readily altered to accommodate different articles.

摘要： A two-piece body high pressure membrane test cell is disclosed with a tangential feed into the interior pressure chamber in which a central distributor element is mounted with the lower frusto-conical end thereof at a critical spacing above a filter membrane. The membrane is supported on an annular land of a filter support disc which has a peripheral edge zone compressed in a sealed fit between the lower and upper pieces of the cell body. The edge zone is machined to a precise thickness to provide a reproducible and accurate spacing between the filter membrane that rests on the support and the lower end of the distributor.

摘要： A housing for single-use pressure filtration units comprises upper and lower parts. A filter element is to be clamped between the housing parts. The upper housing part, preferably molded in one piece of synthetic material, includes a plurality of radial ribs which hold the filter element down, and a baffle disk supported solely by the ribs. The disk is spaced beneath the axial inlet duct to prevent direct impingement of axially incoming pressurized fluid against the filter element. Only some of the ribs support the disk, the remaining ribs terminating short of the disk to promote uniform radial distribution of fluid deflected by the disk. Radially inner ends of the disk support ribs are inclined downwardly and inwardly and act in funnel-like fashion on the inflowing fluid.

摘要： A pressure filtration apparatus including an upper portion with an inflow channel and a discharge channel for the concentrate and a lower portion with a filter support and a discharge channel for the filtrate, the upper and lower portions being releaseably connectable with one another while forming a pressure space. The apparatus contains a distributor plate whose underside is disposed parallel to the upper side of the filter and snugly above the latter while forming an intervening space, and in the center of which is an opening for the concentrate discharge channel. The outer edge of the distributor plate forms a small annular opening which extends all around closely against a basically vertically interior of the pressure space. The top side of the distributor plate has a peripherally raised outer edge which while forming a narrow annular clearance extends to close up against a downwardly pointing horizontal interior wall of the upper portion. The distributor plate has an annular distributor ring surface which grows steadily deeper from the outer edge toward the center of the distributor plate and in the center has a short connecting bushing by way of which the distributor plate is secured to the upper portion and through which the discharge channel for the concentrate runs. The apparatus also includes an inflow channel which opens up in the upper portion in the region of the deepest point of the distributor ring surface above the latter, and at least along a length disposed in front of the opening determining the direction of flow of the emerging inflow current, slopes toward the horizontal at an angle of about 35.degree. to about 55.degree., preferably about 45.degree., and relative to the vertical projection of its axis runs basicaly tangentially to the vertical projection of the distributor ring surface.In preferred embodiments of the invention, the upper portion, lower portion, the distributor plate, the inflow channel, the inflow channel bushing, the filter support, the filtrate discharge channel, and the filtrate discharge bushing may be made of polytetrafluoroethylene (PTFE). If all are made of PTFE, the inflow, the concentrate and the filtrate will be in contact only with PTFE.

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 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： 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.

摘要： A pressure filtering device includes a cylindrical center part, an upper part, a lower part, a first connecting means for detachably connecting the upper part to the upper end of the center part with a fluid-tight connection and a second connecting means for detachably connecting the lower part to the lower end of the center part with a fluid-tight connection. An inlet is provided on the upper part, an outlet and a filter support are provided on the lower part, and a filter element is disposed on the filter support. A disc plate is formed integrally in the center part which can support a magnetic stirring means, the filter element being disposed between the filter support and the disc plate and being spaced from the disc plate so that the inlet side of the filter element does not contact the disc plate during assembly and operation of the pressure filtering apparatus, the first and second connecting means being constructed and arranged to provide for connecting of the upper part to the lower part with a fluid-tight connection, thereby providing for use of the pressure filtering apparatus with or without the center part.
