Abstract: Disclosed herein are systems and methods for measuring and controlling a flow rate through a particle counter or active air sampler. As disclosed herein, a fluid flows through a venturi tube and an orifice in the system at a predetermine velocity. A pressure differential between an inlet of the instrument and a throat section of the venturi tube is measured. The flow rate through the system can be determined based on the pressure differential and an intensive property of the fluid. An alarm can be activated when the flow rate is outside of a flow rate range.

Abstract: Disclosed herein are systems and methods for measuring and controlling a flow rate through a particle counter or active air sampler. As disclosed herein, a flow is created within a conduit fluidly connected to an instrument at a first velocity. An inlet pressure at an inlet of the instrument and an ambient pressure proximate the instrument are measured. The flow rate through the instrument is determined based on a pressure differential between the inlet pressure and the ambient pressure. The flow rate is increased or decreased when the flow rate is outside a flow rate range.

Abstract: An axial piston device configuration that includes a drive shaft, a piston block, pistons, a constant velocity joint assembly, a drive plate coupled to the constant velocity joint assembly, a swash plate, shoes, and piston rods may be provided. The piston block has an interior that is coupled to the drive shaft via a first torque transmitting mechanical interface. The constant velocity joint assembly includes multiple components, at least one of which is coupled to the drive shaft via a second torque transmitting mechanical interface.

Abstract: A telecommunications cable management system includes trough elements including a planar top surface and sides for cable routing and management. The trough elements are made from separate parts assembled together with a mating arrangement. The mating arrangement allows assembly of the system on site, such as by snapping the parts together. The trough elements are then assembled together to form the cable management system.

Abstract: A cable seal assembly includes a sealing member, a first housing member, and a second housing member. The sealing member defines a passageway that extends from a center opening of the sealing member through the periphery of the sealing member. The first housing member is disposed in the passageway and the center opening of the sealing member and defines a cutout portion. The second housing member is disposed in the center opening of the sealing member and engaged with the cutout portion of the first housing member. The first housing member and the second housing member cooperatively define a central axial passage having an inner surface.
