A bench-top dust collector has a front or intake side where air is directed by a cowling into a pre-filter and then a final filter that are held in a frame. A rear compartment holds an array of small high velocity fans that pull the air through the filters to a plenum in the rear compartment. The filtered air in the plenum is discharged through a grill in a downward and rearward direction. The unit is compact and configured to be about the size and shape of an attaché case.

An implantable drainage device is provided. The device is adapted to move body fluid from one part of the body of a patient to another part of the body.

A blood clot removal device for removing blood clots from the vascular system of a patient is implantable in the patient's body. The blood clot removal device comprises a blood flow passageway to be connected to the patient's vascular system to allow circulation of the patient's blood through the blood flow passageway, a filter provided in the blood flow passageway for collecting blood clots occurring in the blood flowing through the blood flow passageway, and a cleaning device for moving blood clots collected by the filter out of the blood flow passageway. By means of such blood clot removal device, the risk of blood clots reaching sensitive areas of the patient's body, such as the brain, is reduced.

A collection device includes a container that retains a collection liquid and that has a channel through which intake gas travels above the collection liquid retained, and a rotating body that is provided inside the container and that rotates around a rotation axis extending in a direction intersecting an up-down direction. The rotating body has a first blade that protrudes in a direction intersecting the rotation axis. The first blade has a filter that captures a target object included in the intake gas. The filter moves, along with rotation of the rotating body around the rotation axis, from a position inside the channel to a position immersed in the collection liquid. Thereby, the collection device collects, into the liquid, the target object included in the intake gas.

The present disclosure relates generally to air intake filter assemblies, and more particularly to air intake assemblies for an outdoor portion of a heating, ventilation, and/or air conditioning (HVAC) system. In an embodiment, a filter assembly is configured to filter an airflow entering an air intake of a HVAC unit. The filter assembly includes a first layer of a first coarse mesh, a second layer of a second coarse mesh, and a fine filter disposed between the first layer and the second layer. Additionally, the fine filter includes an upper level and a lower level with respect to the airflow, and wherein the lower level facilitates accumulation of fine debris captured from the airflow entering the air intake of the HVAC unit.

A particulate collector includes a housing having an air intake port and an exhaust port and a flow channel, in the housing, connecting the two ports, a fan rotatable about an R-axis to generate airflow in the flow channel, a spray unit that sprays first liquid into a first portion in the flow channel, a first filter located between the first portion and the exhaust port and supported rotatably about the R-axis, a power source that rotates the first filter, a first collection port for collecting a first particulate covered with liquid contained in the first liquid from the flow channel through a second portion in the first filter, and a second collection port for collecting a second particulate covered with liquid contained in the first liquid from the flow channel through a third portion in the first filter. The second portion is located between the first and third portions.

A self-cleaning magnetic filter for removing ferrous contaminates from a natural gas process stream including a housing through which the process stream follows for removing ferrous contaminates in the process stream by magnetic attraction with a plurality of magnetic bars that are removably disposed in a plurality of non-magnetic sleeves disposed within the housing. A recirculating washing solution is used to flush contaminates that adhere to the exterior surfaces of the non-magnetic sleeves and from the housing. A bag filter is used to remove contaminates from the washing solution to allow recycling the washing solution.

The present invention relates to a filtering device for removing particles from a bodily fluid of a patient, the filtering device being implantable in the patient's body. The device has a tube forming a main fluid passageway for bodily fluid, through which the bodily fluid of the patient passes when the tube is implanted in the patient, a filter connected to the tube and a filter cleaning device for cleaning the filter by moving particles collected by the filter out of the fluid passageway, wherein the filter cleaning device is adapted to replace the first filter in the fluid passageway with a second filter, thereby moving the particles collected by the first filter out of the fluid passageway.

The present invention relates to a method of implanting a blood clot removal device in a patient's body, by cutting the skin of the patient's body, dissecting an area of the patient's vascular system, placing the blot clot removal device at the dissected area, and connecting a blood flow passageway of the blood clot removal device to the patient's vascular system to allow circulation of the patient's blood through the blood flow passageway.

A filtering device for removing particles from a bodily fluid of a patient is disclosed. The device is implantable in the patient's body and comprises a tube forming a main fluid passageway for bodily fluid, through which the bodily fluid passes when the tube is implanted, wherein the tube is sized and adapted to be fluidly connected to the bodily fluid. The device further comprises a filter connected to the tube, and a filter cleaning device for cleaning the filter.
