A filtration element assembly for use with a cylindrical filter casing has a prismatic support body with a support body interior space. The side walls of the support body form a polygonal outer cross-sectional shape defining a circumscribed circle with a diameter less than or equal to the casing diameter. At least one side wall has an inlet flow passage with a receiving channel surrounding it. A porous filtration structure is disposed within the receiving channel so as to cover the inlet flow passage. A clamping member attached to each of the at least one side wall has a framing portion and a flange portion. The framing portion has a flow window formed there-through in registration with the inlet flow passage. The flange portion extends from the framing portion and is sized and configured for reception into the receiving channel to engage and retain the filtration element within the channel.

A linear compressor includes a compressor body configured to compress a refrigerant. The compressor body includes a cylinder, a discharge valve, a groove, a gas hole, and a flow restrictor. The cylinder receives a piston. The discharge valve is configured to open and close one side of the cylinder and define a compression space for the refrigerant together with the piston. The groove is defined in an outer circumferential surface of the cylinder and into which at least a portion of the refrigerant discharged through the discharge valve is introduced. The gas hole is defined in the groove to pass through the cylinder. The flow restrictor includes twisting wires made of different materials and is disposed to be wound around the groove.

Disclosed is a compact separation system suitable for separating components of a multiphase fluid stream. The compact separation system utilizes a cylindrical cyclone in conjunction with a filtration system. The filtration system incorporates filtration media having at least one of the following characteristics: hydrophilic-oleophobic characteristics or oleophilic-hydrophobic characteristics. The separation system is configured to substantially preclude gas under-carrying into the liquid conduit lines.

A clothes dryer including a device and space for fixing a dryer sheet inside a main body. The clothes dryer includes: a main body including a laundry inlet: a drum rotatably installed inside the main body; a discharge flow path configured to discharge inside air of the drum to outside of the drum; and a sheet receiver accommodating a dryer sheet for providing fragrance to inside of the drum, the sheet receiver positioned on the discharge flow path and detachably installed in the main body.

A system directed to providing a self-contained negative pressure environment (SCONE) to remove airborne particulates emitted from a patient. The system prevents exposure to pathogenic biological airborne particulates during triage, transportation, and treatment, including aerosol generating procedures (AGPs) and end of life care. This system is directed to a collapsible device having a flexible cover covering two support members, with openings in the flexible cover such that medical professionals can reach in and operate within. The present invention is further adaptable to patients and operating environments of various sizes.

A device for filtering air comprising a base, a fan functionally attached to the base, an air filter releasable attached to the base, and a substantially air impermeable outer sleeve is provided.

A laundry treatment equipment includes a cleaning device for cleaning a lint filtration device, and a control system adjusts a connection relation between the lint filtration device and the laundry treatment equipment according to the operating state of the laundry treatment equipment and/or the operating state of the cleaning devices. A vibration detection device or a position detection device are provided to detect a vibration state or a position state of the lint filtration device during the operation of the equipment, so that the control system can obtain vibration information or position information of the lint filtration device at every moment, and data support is provided for other applications. Through the laundry treatment equipment, a user can install and remove the lint filtration device and know the lint clearing condition more flexibly and conveniently with the cooperation of the control system.

The present invention is directed to a gladhand connector having multiple ports and an integrated filter. The connector has a base that includes an air hose connector clamp on a first surface, and a first access port extending from the first surface toward a second surface, and a second access port on a bottom surface. The access ports are in fluid communication with an intermediate conduit configured to direct air received from an air hose through the housing. The connector also comprises a receptacle adjacent the first access port and in fluid communication with one of the access ports. The receptacle is configured to receive a pressure sensitive, removable and replaceable filter assembly that is configured to filter debris. The filter assembly is displaceable by air pressure of received air. The connector further comprises a mounting bracket configured to be attached to a vehicle.

Air filter system includes a main housing, in which a primary filter cartridge can operably be installed, the housing includes a clean air outlet and a service opening through which the primary filter cartridge can be installed, a pre-separator assembly mounted onto and closing off the service opening, the pre-separator assembly having an inlet flow face receiving air to be cleaned from the outside, an outlet flow face through which pre-cleaned air exits, the outlet flow face positioned over the service opening of the main housing, such that pre-cleaned air is provided to the main housing, a dust discharge port, through which particles pre-separated by the pre-separator can be discharged, wherein the main housing comprises a connection port operable to sealingly connect to the dust discharge port on one side and sealingly connect a scavenge line on the other side, the connection port operable to connect the dust discharge port and a scavenge line.

The present disclosure provides three-dimensional (3D) printing processes, apparatuses, software, and systems for controlling and/or treating gas borne debris in an atmosphere of a 3D printer.
