  • Patent number: 11890559
    Abstract: A liquid recovery filter assembly for recovering filtered liquid trapped within a core or downstream side of a filter element. Multiple embodiments each include a recovery port and a recovery filter in fluid communication with the core or downstream side of the filter element. The recovery port is opened following filtration operations to permit and to facilitate filtered liquid to flow from a downstream or outlet port, thus allowing recovery of liquid remaining in the filter core or downstream side following filtering operations. The recovery filter permits the introduction of pressurized gas to force the filtered liquids from the filter assembly without compromising the sterility and/or non-contaminant condition of the liquid.

  • Patent number: 11691097
    Abstract: A transmission filter includes two outlets. One outlet, adapted to feed an engine-driven pump, protrudes diagonally from the front of the filter. The first outlet is sealed to the inlet of the engine-driven pump by a radial seal. The second outlet is arranged in a rear extension and is sealed to the inlet of an electric pump by a compression seal. The differing types of seals and relative orientations of the outlets make the assembly less sensitive to dimension variation due to production and assembly tolerances. The relative locations of the outlets also mitigate any flow interactions between the pumps when both operate simultaneously.

  • Patent number: 8857627
    Abstract: A blood processing filter including a flexible container (having an inlet and an outlet and a sheet-like filter member that is assembled in the flexible container) has a seal part that seals the flexible container and the filter member to form an effective filtration portion of the filter member and a partition part that seals the flexible container and the filter member to partition the effective filtration portion into a plurality of areas. The seal part and the partition part cooperate with the filter member to divide inside of the flexible container into three or more internal spaces including an inlet space that communicates with the inlet, and an outlet space that communicates with the outlet, and also form, as a blood channel, a channel that passes through each of three or more of the internal spaces and also passes multiple times through the filter member.

  • Patent number: 8858794
    Abstract: A waste/sediment collecting container has a front vertical wall, a back vertical wall, two side vertical walls, and a sloped bottom surface. Along the lowest portion of the sloped floor surface lays a debris grate which allows water and pieces of sediment to pass through (but prevents larger pieces of waste from passing). The collection container includes a sump directly beneath the debris grate for collecting heavy sediment which passes through the grate. Sloped walls along the sides of the sump lead to U-traps on both sides of the container that allow liquid to pass through but prevent any solid waste from leaving the sump. Solid waste may be removed from the sump by removing the threaded service cap from the drain hole. Located beyond the traps are filter chambers having drain holes for inserting sediment filters which liquid passes through and exits the container.

  • Patent number: 8840787
    Abstract: A filter device, in particular a return line suction filter, has at least one filter housing (3) receiving a filter element (17) defining a longitudinal axis. The filter element has an end cap with an enclosure at one filter element end enclosing an end edge of the filter material (39) and fixed to an element receptacle (5) connected to the filter housing (3) for fixing the location of the filter element (17) in its functional position. The element receptacle (5) and the associated end cap (21) of the filter element (17) have design irregularities (63, 65) adapted to each other at their parts (23, 47) engaging each other in the functional position of the filter element (17). The irregularities enable the engagement in a positional alignment to each other.
