Abstract:
A filter assembly for a fuel delivery system for actuators and fuel control system of an aircraft engine includes a wash flow filter. Fuel flow velocity is increased through the filter through use of a recirculating passage that is effectively achieved through use of an ejector pump. A portion of the pressurized fuel delivered by the main fuel pump is diverted and serves as a motive fluid that scavenges unfiltered flow from downstream of the filter and recirculates or discharges the recirculated flow to an inlet of the filter. This provides increased velocity to maintain sufficient washing of the filter openings.
Abstract:
A manifold and filter assembly for use with a waste collection unit is provided. The manifold and filter assembly directs and filters medical waste flowing into the waste collection unit. The manifold and filter assembly comprises a manifold body defining a chamber and an outlet (19) for directing the medical waste into the waste collection unit. A manifold cap (46) is fitted to the manifold body to close the chamber. The manifold cap defines a plurality of inlets (48) for receiving the medical waste. A filter basket (20) having a bottom and a peripheral wall (30) defining a plurality of openings (42) is snap-locked to the manifold body. The filter basket (20) is positioned such that a fluid bypass (28) is formed between the filter basket (20) and the manifold body and between the filter basket (20) and the manifold cap (46). The fluid bypass (28) is in fluid communication with the outlet whereby the medical waste can flow over the peripheral wall (30) to the outlet (19) through the fluid bypass.
Abstract:
It is required to provide a gas hydrate dewatering device which performs dewatering and produces a gas hydrate with a low proportion of included water continuously at high efficiency, under conditions in which the gas hydrate is not decomposed and the water is not frozen into ice. This is achieved by providing a dewatering device (12) for gas hydrate slurry which eliminates the water from a slurry in which gas hydrate is dispersed in water, including a dewatering mechanism of a screw press type within an environment which is maintained at temperature and pressure conditions at which the gas hydrate does not decompose and the water does not freeze.
Abstract:
The invention relates to a storm water drain pit comprising: an inlet for storm water; a filter for removing particles from the storm water, comprising a cylindrical body comprising coherent man-made vitreous fibres (MMVF) bonded with a cured binder composition; wherein the cylindrical body has a hollow centre and an outer wall; a guide element for guiding water from the inlet into the cylindrical body; a sedimentation chamber for sedimentation of particles from the storm water, wherein the cylindrical body is positioned below the inlet and above the sedimentation chamber; an outlet for filtered water; wherein the outlet is positioned above the sedimentation chamber and below the inlet; and a separation element for separating the sedimentation chamber from the outlet; wherein the cylindrical body has a density in the range of 50 to 200 kg/m 3 , a binder content in the range of 2 to 5 wt% and the outer wall has a circumferential thickness in the range of 2 cm to 20 cm.
Abstract:
The present invention provides a filtering system including an impermeable extension for a filtering element. The filtering element includes a core, a filtering medium, a cap, and an extension. During installation, the filtering element is operable to be inserted into and secured in the vessel using the extension. During use, the pressurized gas enters the vessel through an inlet, passes through the filtering element, and exits the vessel through an outlet. During maintenance or replacement, the filtering element is operable to be removed from the vessel using the extension.
