A microfabricated sheath flow structure for producing a sheath flow includes a primary sheath flow channel for conveying a sheath fluid, a sample inlet for injecting a sample into the sheath fluid in the primary sheath flow channel, a primary focusing region for focusing the sample within the sheath fluid and a secondary focusing region for providing additional focusing of the sample within the sheath fluid. The secondary focusing region may be formed by a flow channel intersecting the primary sheath flow channel to inject additional sheath fluid into the primary sheath flow channel from a selected direction. A sheath flow system may comprise a plurality of sheath flow structures operating in parallel on a microfluidic chip.

A fluid-floated conveying device includes a multi-channel space conversion cabin. An upper channel port is provided with a floating ball outlet gate which is communicated with a water pipe filled with a liquid. A side channel port is provided with a floating ball inlet gate communicated with the external atmosphere. A lower channel port is connected to a water storage pressure cylinder or a water discharging pipe. A floating ball carries articles and enters the cleared space conversion cabin from the side channel. The floating ball inlet gate of the side channel is closed, the cabin is filled with water, the floating ball outlet gate of the upper channel is opened, the floating ball rises and enters from the upper channel port, the communicated water pipe filled with the liquid, the water buoyancy enables the floating ball to rise, and the carried articles are conveyed to a receiving platform.

The disclosure relates to a feeding device for guiding and providing one-piece ties, with a hose unit and a funnel unit. The hose unit is designed to guide a respective one-piece tie in a hose inner via an air flow along the hose unit towards an outlet end of the hose unit and subsequently in an outlet direction out of the outlet end of the hose unit to the funnel unit. The funnel unit is arranged at the outlet end of the hose unit on the hose unit and is designed to receive the respective one-piece tie guided through the hose unit.

A workstation includes a housing and a pneumatic tube port sized and shaped to connect to tubing of a pneumatic tube delivery system. The workstation includes a carrier dispatch and arrival mechanism coupling to the pneumatic tube port and having an outlet and a slide plate movable from a position opening the outlet to a position closing the outlet. The carrier dispatch and arrival mechanism further including a dispatch arm for loading an outbound carrier for transportation from the workstation through the pneumatic tube delivery system to a further workstation. The workstation further comprises an equipment storage compartment adjacent to the carrier dispatch and arrival mechanism and a bin at the bottom of the housing sized and shaped to receive and store the inbound carriers in combination with a user interface cabinet housing a user interface apparatus and a space for supporting stored carriers.
