Abstract: The filtration device enables the separation and collection of dust and particles produced by the pads of a brake assembly. A first separation unit having an air filtration medium, typically annular, is provided in the housing of the device, in order to define an upstream zone where air is admitted, for example tangentially, and a downstream zone in communication with an outlet of the housing for discharging the purified air. The upstream zone is in communication with a lower stage situated lower down, in which a second separation unit is located in order to separate water from particles that have fallen from the upstream zone. A filtration by the second unit is intended to collect clean water and possibly to discharge this water by gravitational flow. The fallen particles remain trapped inside the device, under the first unit.

Abstract: This document provides a dual flask for laboratory use, methods of using a dual flask, and systems including a dual flask. A dual flask can include a first flask structure and a second flask structure. Each flask structure can include a body and a neck. The first body and the second body in a dual flask provided herein can be connected together and have a filter there between such that fluids can be filtered between said first and second bodies.

Abstract: A liquid block apparatus integrated into a sample probe that is inserted into the pressurized process to prevent entrained liquids from entering the probe and being extracted for sampling. The present invention enhances sampling of pressurized process fluids for on-stream and spot sampling of pressurized process fluid such as natural gas or the like, particularly pressurized process gas having liquid entrained therein, or otherwise referenced as multiphase or “wet”.

Abstract: Disclosed is a drain discharge apparatus comprising a float provided displaceably in response to drain stored at the inside of a filter case, a handle formed with a drain discharge port for discharging the drain stored in the filter case to the outside, and a swinging mechanism for operating a valve plug for opening and closing the drain discharge port by the aid of a lever linked to displacement of the float.

Abstract: In a reducing valve assembly having a fluid inlet port and a fluid outlet port with a main valve for controlling flow between the inlet and outlet port, the main valve includes a main valve member which is actuated by an operating piston including a piston rod. In order to improve the flow characteristics of the assembly, a movable wall of the piston which transmits displacement through the piston rod to the valve member is connected with the piston rod by shaping the wall extending therebetween with a spherically curved configuration outwardly in a diametral direction from the piston rod.

Abstract: In a reducing valve assembly including a vapor-liquid separator, a valve casing, having therein a valve mechanism defining a valve orifice and defining inlet and outlet openings having the reducing valve mechanism interposed therebetween, is arranged with the valve casing extended below the reducing valve to define a sump chamber, the extended portion of the casing extending from a part thereof which surrounds the valve orifice. An annular partition is provided at the upper part of the sump chamber to form an annular space between the partition and the extended portion of the valve casing, the annular space being arranged to communicate with the inlet opening from above and with the sump chamber from below.

Abstract: The specification discloses a medical suction apparatus including a canister for receiving and containing fluid and a lid for sealably covering the canister. A patient port and a vacuum port extend through the lid, and a vertically slidable overflow plunger is provided for selectively blocking the vacuum port. A plunger guide directs the plunger towards the vacuum port, and a float is attached to the bottom of the plunger. When the fluid within the canister is below a predetermined level, the plunger and the float are supported at their lowermost position. As the fluid level rises, the float causes the plunger to be moved upwardly to close the vacuum port. An outer sleeve downwardly depends from the lid and partially encompasses the float for providing a tortuous path for air and fluid through the vacuum port to prevent direct migration of aerosol droplets, fluid droplets and condensation through the vacuum port.
